The table for translating pcre_compile() error codes into POSIX error codes + was out-of-date, and there was no check on the pcre_compile() error code + being within the table. This could lead to an OK return being given in + error. + +2. Changed the call to open a subject file in pcregrep from fopen(pathname, + "r") to fopen(pathname, "rb"), which fixed a problem with some of the tests + in a Windows environment. + +3. The pcregrep --count option prints the count for each file even when it is + zero, as does GNU grep. However, pcregrep was also printing all files when + --files-with-matches was added. Now, when both options are given, it prints + counts only for those files that have at least one match. (GNU grep just + prints the file name in this circumstance, but including the count seems + more useful - otherwise, why use --count?) Also ensured that the + combination -clh just lists non-zero counts, with no names. + +4. The long form of the pcregrep -F option was incorrectly implemented as + --fixed_strings instead of --fixed-strings. This is an incompatible change, + but it seems right to fix it, and I didn't think it was worth preserving + the old behaviour. + +5. The command line items --regex=pattern and --regexp=pattern were not + recognized by pcregrep, which required --regex pattern or --regexp pattern + (with a space rather than an '='). The man page documented the '=' forms, + which are compatible with GNU grep; these now work. + +6. No libpcreposix.pc file was created for pkg-config; there was just + libpcre.pc and libpcrecpp.pc. The omission has been rectified. + +7. Added #ifndef SUPPORT_UCP into the pcre_ucd.c module, to reduce its size + when UCP support is not needed, by modifying the Python script that + generates it from Unicode data files. This should not matter if the module + is correctly used as a library, but I received one complaint about 50K of + unwanted data. My guess is that the person linked everything into his + program rather than using a library. Anyway, it does no harm. + +8. A pattern such as /\x{123}{2,2}+/8 was incorrectly compiled; the trigger + was a minimum greater than 1 for a wide character in a possessive + repetition. The same bug could also affect patterns like /(\x{ff}{0,2})*/8 + which had an unlimited repeat of a nested, fixed maximum repeat of a wide + character. Chaos in the form of incorrect output or a compiling loop could + result. + +9. The restrictions on what a pattern can contain when partial matching is + requested for pcre_exec() have been removed. All patterns can now be + partially matched by this function. In addition, if there are at least two + slots in the offset vector, the offset of the earliest inspected character + for the match and the offset of the end of the subject are set in them when + PCRE_ERROR_PARTIAL is returned. + +10. Partial matching has been split into two forms: PCRE_PARTIAL_SOFT, which is + synonymous with PCRE_PARTIAL, for backwards compatibility, and + PCRE_PARTIAL_HARD, which causes a partial match to supersede a full match, + and may be more useful for multi-segment matching. + +11. Partial matching with pcre_exec() is now more intuitive. A partial match + used to be given if ever the end of the subject was reached; now it is + given only if matching could not proceed because another character was + needed. This makes a difference in some odd cases such as Z(*FAIL) with the + string "Z", which now yields "no match" instead of "partial match". In the + case of pcre_dfa_exec(), "no match" is given if every matching path for the + final character ended with (*FAIL). + +12. Restarting a match using pcre_dfa_exec() after a partial match did not work + if the pattern had a "must contain" character that was already found in the + earlier partial match, unless partial matching was again requested. For + example, with the pattern /dog.(body)?/, the "must contain" character is + "g". If the first part-match was for the string "dog", restarting with + "sbody" failed. This bug has been fixed. + +13. The string returned by pcre_dfa_exec() after a partial match has been + changed so that it starts at the first inspected character rather than the + first character of the match. This makes a difference only if the pattern + starts with a lookbehind assertion or \b or \B (\K is not supported by + pcre_dfa_exec()). It's an incompatible change, but it makes the two + matching functions compatible, and I think it's the right thing to do. + +14. Added a pcredemo man page, created automatically from the pcredemo.c file, + so that the demonstration program is easily available in environments where + PCRE has not been installed from source. + +15. Arranged to add -DPCRE_STATIC to cflags in libpcre.pc, libpcreposix.cp, + libpcrecpp.pc and pcre-config when PCRE is not compiled as a shared + library. + +16. Added REG_UNGREEDY to the pcreposix interface, at the request of a user. + It maps to PCRE_UNGREEDY. It is not, of course, POSIX-compatible, but it + is not the first non-POSIX option to be added. Clearly some people find + these options useful. + +17. If a caller to the POSIX matching function regexec() passes a non-zero + value for nmatch with a NULL value for pmatch, the value of + nmatch is forced to zero. + +18. RunGrepTest did not have a test for the availability of the -u option of + the diff command, as RunTest does. It now checks in the same way as + RunTest, and also checks for the -b option. + +19. If an odd number of negated classes containing just a single character + interposed, within parentheses, between a forward reference to a named + subpattern and the definition of the subpattern, compilation crashed with + an internal error, complaining that it could not find the referenced + subpattern. An example of a crashing pattern is /(?&A)(([^m])(?))/. + [The bug was that it was starting one character too far in when skipping + over the character class, thus treating the ] as data rather than + terminating the class. This meant it could skip too much.] + +20. Added PCRE_NOTEMPTY_ATSTART in order to be able to correctly implement the + /g option in pcretest when the pattern contains \K, which makes it possible + to have an empty string match not at the start, even when the pattern is + anchored. Updated pcretest and pcredemo to use this option. + +21. If the maximum number of capturing subpatterns in a recursion was greater + than the maximum at the outer level, the higher number was returned, but + with unset values at the outer level. The correct (outer level) value is + now given. + +22. If (*ACCEPT) appeared inside capturing parentheses, previous releases of + PCRE did not set those parentheses (unlike Perl). I have now found a way to + make it do so. The string so far is captured, making this feature + compatible with Perl. + +23. The tests have been re-organized, adding tests 11 and 12, to make it + possible to check the Perl 5.10 features against Perl 5.10. + +24. Perl 5.10 allows subroutine calls in lookbehinds, as long as the subroutine + pattern matches a fixed length string. PCRE did not allow this; now it + does. Neither allows recursion. + +25. I finally figured out how to implement a request to provide the minimum + length of subject string that was needed in order to match a given pattern. + (It was back references and recursion that I had previously got hung up + on.) This code has now been added to pcre_study(); it finds a lower bound + to the length of subject needed. It is not necessarily the greatest lower + bound, but using it to avoid searching strings that are too short does give + some useful speed-ups. The value is available to calling programs via + pcre_fullinfo(). + +26. While implementing 25, I discovered to my embarrassment that pcretest had + not been passing the result of pcre_study() to pcre_dfa_exec(), so the + study optimizations had never been tested with that matching function. + Oops. What is worse, even when it was passed study data, there was a bug in + pcre_dfa_exec() that meant it never actually used it. Double oops. There + were also very few tests of studied patterns with pcre_dfa_exec(). + +27. If (?| is used to create subpatterns with duplicate numbers, they are now + allowed to have the same name, even if PCRE_DUPNAMES is not set. However, + on the other side of the coin, they are no longer allowed to have different + names, because these cannot be distinguished in PCRE, and this has caused + confusion. (This is a difference from Perl.) + +28. When duplicate subpattern names are present (necessarily with different + numbers, as required by 27 above), and a test is made by name in a + conditional pattern, either for a subpattern having been matched, or for + recursion in such a pattern, all the associated numbered subpatterns are + tested, and the overall condition is true if the condition is true for any + one of them. This is the way Perl works, and is also more like the way + testing by number works. + + +Version 7.9 11-Apr-09 +--------------------- + +1. When building with support for bzlib/zlib (pcregrep) and/or readline + (pcretest), all targets were linked against these libraries. This included + libpcre, libpcreposix, and libpcrecpp, even though they do not use these + libraries. This caused unwanted dependencies to be created. This problem + has been fixed, and now only pcregrep is linked with bzlib/zlib and only + pcretest is linked with readline. + +2. The "typedef int BOOL" in pcre_internal.h that was included inside the + "#ifndef FALSE" condition by an earlier change (probably 7.8/18) has been + moved outside it again, because FALSE and TRUE are already defined in AIX, + but BOOL is not. + +3. The pcre_config() function was treating the PCRE_MATCH_LIMIT and + PCRE_MATCH_LIMIT_RECURSION values as ints, when they should be long ints. + +4. The pcregrep documentation said spaces were inserted as well as colons (or + hyphens) following file names and line numbers when outputting matching + lines. This is not true; no spaces are inserted. I have also clarified the + wording for the --colour (or --color) option. + +5. In pcregrep, when --colour was used with -o, the list of matching strings + was not coloured; this is different to GNU grep, so I have changed it to be + the same. + +6. When --colo(u)r was used in pcregrep, only the first matching substring in + each matching line was coloured. Now it goes on to look for further matches + of any of the test patterns, which is the same behaviour as GNU grep. + +7. A pattern that could match an empty string could cause pcregrep to loop; it + doesn't make sense to accept an empty string match in pcregrep, so I have + locked it out (using PCRE's PCRE_NOTEMPTY option). By experiment, this + seems to be how GNU grep behaves. + +8. The pattern (?(?=.*b)b|^) was incorrectly compiled as "match must be at + start or after a newline", because the conditional assertion was not being + correctly handled. The rule now is that both the assertion and what follows + in the first alternative must satisfy the test. + +9. If auto-callout was enabled in a pattern with a conditional group whose + condition was an assertion, PCRE could crash during matching, both with + pcre_exec() and pcre_dfa_exec(). + +10. The PCRE_DOLLAR_ENDONLY option was not working when pcre_dfa_exec() was + used for matching. + +11. Unicode property support in character classes was not working for + characters (bytes) greater than 127 when not in UTF-8 mode. + +12. Added the -M command line option to pcretest. + +14. Added the non-standard REG_NOTEMPTY option to the POSIX interface. + +15. Added the PCRE_NO_START_OPTIMIZE match-time option. + +16. Added comments and documentation about mis-use of no_arg in the C++ + wrapper. + +17. Implemented support for UTF-8 encoding in EBCDIC environments, a patch + from Martin Jerabek that uses macro names for all relevant character and + string constants. + +18. Added to pcre_internal.h two configuration checks: (a) If both EBCDIC and + SUPPORT_UTF8 are set, give an error; (b) If SUPPORT_UCP is set without + SUPPORT_UTF8, define SUPPORT_UTF8. The "configure" script handles both of + these, but not everybody uses configure. + +19. A conditional group that had only one branch was not being correctly + recognized as an item that could match an empty string. This meant that an + enclosing group might also not be so recognized, causing infinite looping + (and probably a segfault) for patterns such as ^"((?(?=[a])[^"])|b)*"$ + with the subject "ab", where knowledge that the repeated group can match + nothing is needed in order to break the loop. + +20. If a pattern that was compiled with callouts was matched using pcre_dfa_ + exec(), but without supplying a callout function, matching went wrong. + +21. If PCRE_ERROR_MATCHLIMIT occurred during a recursion, there was a memory + leak if the size of the offset vector was greater than 30. When the vector + is smaller, the saved offsets during recursion go onto a local stack + vector, but for larger vectors malloc() is used. It was failing to free + when the recursion yielded PCRE_ERROR_MATCH_LIMIT (or any other "abnormal" + error, in fact). + +22. There was a missing #ifdef SUPPORT_UTF8 round one of the variables in the + heapframe that is used only when UTF-8 support is enabled. This caused no + problem, but was untidy. + +23. Steven Van Ingelgem's patch to CMakeLists.txt to change the name + CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE is + included within another project. + +24. Steven Van Ingelgem's patches to add more options to the CMake support, + slightly modified by me: + + (a) PCRE_BUILD_TESTS can be set OFF not to build the tests, including + not building pcregrep. + + (b) PCRE_BUILD_PCREGREP can be see OFF not to build pcregrep, but only + if PCRE_BUILD_TESTS is also set OFF, because the tests use pcregrep. + +25. Forward references, both numeric and by name, in patterns that made use of + duplicate group numbers, could behave incorrectly or give incorrect errors, + because when scanning forward to find the reference group, PCRE was not + taking into account the duplicate group numbers. A pattern such as + ^X(?3)(a)(?|(b)|(q))(Y) is an example. + +26. Changed a few more instances of "const unsigned char *" to USPTR, making + the feature of a custom pointer more persuasive (as requested by a user). + +27. Wrapped the definitions of fileno and isatty for Windows, which appear in + pcretest.c, inside #ifndefs, because it seems they are sometimes already + pre-defined. + +28. Added support for (*UTF8) at the start of a pattern. + +29. Arrange for flags added by the "release type" setting in CMake to be shown + in the configuration summary. + + +Version 7.8 05-Sep-08 +--------------------- + +1. Replaced UCP searching code with optimized version as implemented for Ad + Muncher (http://www.admuncher.com/) by Peter Kankowski. This uses a two- + stage table and inline lookup instead of a function, giving speed ups of 2 + to 5 times on some simple patterns that I tested. Permission was given to + distribute the MultiStage2.py script that generates the tables (it's not in + the tarball, but is in the Subversion repository). + +2. Updated the Unicode datatables to Unicode 5.1.0. This adds yet more + scripts. + +3. Change 12 for 7.7 introduced a bug in pcre_study() when a pattern contained + a group with a zero qualifier. The result of the study could be incorrect, + or the function might crash, depending on the pattern. + +4. Caseless matching was not working for non-ASCII characters in back + references. For example, /(\x{de})\1/8i was not matching \x{de}\x{fe}. + It now works when Unicode Property Support is available. + +5. In pcretest, an escape such as \x{de} in the data was always generating + a UTF-8 string, even in non-UTF-8 mode. Now it generates a single byte in + non-UTF-8 mode. If the value is greater than 255, it gives a warning about + truncation. + +6. Minor bugfix in pcrecpp.cc (change "" == ... to NULL == ...). + +7. Added two (int) casts to pcregrep when printing the difference of two + pointers, in case they are 64-bit values. + +8. Added comments about Mac OS X stack usage to the pcrestack man page and to + test 2 if it fails. + +9. Added PCRE_CALL_CONVENTION just before the names of all exported functions, + and a #define of that name to empty if it is not externally set. This is to + allow users of MSVC to set it if necessary. + +10. The PCRE_EXP_DEFN macro which precedes exported functions was missing from + the convenience functions in the pcre_get.c source file. + +11. An option change at the start of a pattern that had top-level alternatives + could cause overwriting and/or a crash. This command provoked a crash in + some environments: + + printf "/(?i)[\xc3\xa9\xc3\xbd]|[\xc3\xa9\xc3\xbdA]/8\n" | pcretest + + This potential security problem was recorded as CVE-2008-2371. + +12. For a pattern where the match had to start at the beginning or immediately + after a newline (e.g /.*anything/ without the DOTALL flag), pcre_exec() and + pcre_dfa_exec() could read past the end of the passed subject if there was + no match. To help with detecting such bugs (e.g. with valgrind), I modified + pcretest so that it places the subject at the end of its malloc-ed buffer. + +13. The change to pcretest in 12 above threw up a couple more cases when pcre_ + exec() might read past the end of the data buffer in UTF-8 mode. + +14. A similar bug to 7.3/2 existed when the PCRE_FIRSTLINE option was set and + the data contained the byte 0x85 as part of a UTF-8 character within its + first line. This applied both to normal and DFA matching. + +15. Lazy qualifiers were not working in some cases in UTF-8 mode. For example, + /^[^d]*?$/8 failed to match "abc". + +16. Added a missing copyright notice to pcrecpp_internal.h. + +17. Make it more clear in the documentation that values returned from + pcre_exec() in ovector are byte offsets, not character counts. + +18. Tidied a few places to stop certain compilers from issuing warnings. + +19. Updated the Virtual Pascal + BCC files to compile the latest v7.7, as + supplied by Stefan Weber. I made a further small update for 7.8 because + there is a change of source arrangements: the pcre_searchfuncs.c module is + replaced by pcre_ucd.c. + + +Version 7.7 07-May-08 +--------------------- + +1. Applied Craig's patch to sort out a long long problem: "If we can't convert + a string to a long long, pretend we don't even have a long long." This is + done by checking for the strtoq, strtoll, and _strtoi64 functions. + +2. Applied Craig's patch to pcrecpp.cc to restore ABI compatibility with + pre-7.6 versions, which defined a global no_arg variable instead of putting + it in the RE class. (See also #8 below.) + +3. Remove a line of dead code, identified by coverity and reported by Nuno + Lopes. + +4. Fixed two related pcregrep bugs involving -r with --include or --exclude: + + (1) The include/exclude patterns were being applied to the whole pathnames + of files, instead of just to the final components. + + (2) If there was more than one level of directory, the subdirectories were + skipped unless they satisfied the include/exclude conditions. This is + inconsistent with GNU grep (and could even be seen as contrary to the + pcregrep specification - which I improved to make it absolutely clear). + The action now is always to scan all levels of directory, and just + apply the include/exclude patterns to regular files. + +5. Added the --include_dir and --exclude_dir patterns to pcregrep, and used + --exclude_dir in the tests to avoid scanning .svn directories. + +6. Applied Craig's patch to the QuoteMeta function so that it escapes the + NUL character as backslash + 0 rather than backslash + NUL, because PCRE + doesn't support NULs in patterns. + +7. Added some missing "const"s to declarations of static tables in + pcre_compile.c and pcre_dfa_exec.c. + +8. Applied Craig's patch to pcrecpp.cc to fix a problem in OS X that was + caused by fix #2 above. (Subsequently also a second patch to fix the + first patch. And a third patch - this was a messy problem.) + +9. Applied Craig's patch to remove the use of push_back(). + +10. Applied Alan Lehotsky's patch to add REG_STARTEND support to the POSIX + matching function regexec(). + +11. Added support for the Oniguruma syntax \g, \g, \g'name', \g'n', + which, however, unlike Perl's \g{...}, are subroutine calls, not back + references. PCRE supports relative numbers with this syntax (I don't think + Oniguruma does). + +12. Previously, a group with a zero repeat such as (...){0} was completely + omitted from the compiled regex. However, this means that if the group + was called as a subroutine from elsewhere in the pattern, things went wrong + (an internal error was given). Such groups are now left in the compiled + pattern, with a new opcode that causes them to be skipped at execution + time. + +13. Added the PCRE_JAVASCRIPT_COMPAT option. This makes the following changes + to the way PCRE behaves: + + (a) A lone ] character is dis-allowed (Perl treats it as data). + + (b) A back reference to an unmatched subpattern matches an empty string + (Perl fails the current match path). + + (c) A data ] in a character class must be notated as \] because if the + first data character in a class is ], it defines an empty class. (In + Perl it is not possible to have an empty class.) The empty class [] + never matches; it forces failure and is equivalent to (*FAIL) or (?!). + The negative empty class [^] matches any one character, independently + of the DOTALL setting. + +14. A pattern such as /(?2)[]a()b](abc)/ which had a forward reference to a + non-existent subpattern following a character class starting with ']' and + containing () gave an internal compiling error instead of "reference to + non-existent subpattern". Fortunately, when the pattern did exist, the + compiled code was correct. (When scanning forwards to check for the + existencd of the subpattern, it was treating the data ']' as terminating + the class, so got the count wrong. When actually compiling, the reference + was subsequently set up correctly.) + +15. The "always fail" assertion (?!) is optimzed to (*FAIL) by pcre_compile; + it was being rejected as not supported by pcre_dfa_exec(), even though + other assertions are supported. I have made pcre_dfa_exec() support + (*FAIL). + +16. The implementation of 13c above involved the invention of a new opcode, + OP_ALLANY, which is like OP_ANY but doesn't check the /s flag. Since /s + cannot be changed at match time, I realized I could make a small + improvement to matching performance by compiling OP_ALLANY instead of + OP_ANY for "." when DOTALL was set, and then removing the runtime tests + on the OP_ANY path. + +17. Compiling pcretest on Windows with readline support failed without the + following two fixes: (1) Make the unistd.h include conditional on + HAVE_UNISTD_H; (2) #define isatty and fileno as _isatty and _fileno. + +18. Changed CMakeLists.txt and cmake/FindReadline.cmake to arrange for the + ncurses library to be included for pcretest when ReadLine support is + requested, but also to allow for it to be overridden. This patch came from + Daniel Bergstrm. + +19. There was a typo in the file ucpinternal.h where f0_rangeflag was defined + as 0x00f00000 instead of 0x00800000. Luckily, this would not have caused + any errors with the current Unicode tables. Thanks to Peter Kankowski for + spotting this. + + +Version 7.6 28-Jan-08 +--------------------- + +1. A character class containing a very large number of characters with + codepoints greater than 255 (in UTF-8 mode, of course) caused a buffer + overflow. + +2. Patch to cut out the "long long" test in pcrecpp_unittest when + HAVE_LONG_LONG is not defined. + +3. Applied Christian Ehrlicher's patch to update the CMake build files to + bring them up to date and include new features. This patch includes: + + - Fixed PH's badly added libz and libbz2 support. + - Fixed a problem with static linking. + - Added pcredemo. [But later removed - see 7 below.] + - Fixed dftables problem and added an option. + - Added a number of HAVE_XXX tests, including HAVE_WINDOWS_H and + HAVE_LONG_LONG. + - Added readline support for pcretest. + - Added an listing of the option settings after cmake has run. + +4. A user submitted a patch to Makefile that makes it easy to create + "pcre.dll" under mingw when using Configure/Make. I added stuff to + Makefile.am that cause it to include this special target, without + affecting anything else. Note that the same mingw target plus all + the other distribution libraries and programs are now supported + when configuring with CMake (see 6 below) instead of with + Configure/Make. + +5. Applied Craig's patch that moves no_arg into the RE class in the C++ code. + This is an attempt to solve the reported problem "pcrecpp::no_arg is not + exported in the Windows port". It has not yet been confirmed that the patch + solves the problem, but it does no harm. + +6. Applied Sheri's patch to CMakeLists.txt to add NON_STANDARD_LIB_PREFIX and + NON_STANDARD_LIB_SUFFIX for dll names built with mingw when configured + with CMake, and also correct the comment about stack recursion. + +7. Remove the automatic building of pcredemo from the ./configure system and + from CMakeLists.txt. The whole idea of pcredemo.c is that it is an example + of a program that users should build themselves after PCRE is installed, so + building it automatically is not really right. What is more, it gave + trouble in some build environments. + +8. Further tidies to CMakeLists.txt from Sheri and Christian. + + +Version 7.5 10-Jan-08 +--------------------- + +1. Applied a patch from Craig: "This patch makes it possible to 'ignore' + values in parens when parsing an RE using the C++ wrapper." + +2. Negative specials like \S did not work in character classes in UTF-8 mode. + Characters greater than 255 were excluded from the class instead of being + included. + +3. The same bug as (2) above applied to negated POSIX classes such as + [:^space:]. + +4. PCRECPP_STATIC was referenced in pcrecpp_internal.h, but nowhere was it + defined or documented. It seems to have been a typo for PCRE_STATIC, so + I have changed it. + +5. The construct (?&) was not diagnosed as a syntax error (it referenced the + first named subpattern) and a construct such as (?&a) would reference the + first named subpattern whose name started with "a" (in other words, the + length check was missing). Both these problems are fixed. "Subpattern name + expected" is now given for (?&) (a zero-length name), and this patch also + makes it give the same error for \k'' (previously it complained that that + was a reference to a non-existent subpattern). + +6. The erroneous patterns (?+-a) and (?-+a) give different error messages; + this is right because (?- can be followed by option settings as well as by + digits. I have, however, made the messages clearer. + +7. Patterns such as (?(1)a|b) (a pattern that contains fewer subpatterns + than the number used in the conditional) now cause a compile-time error. + This is actually not compatible with Perl, which accepts such patterns, but + treats the conditional as always being FALSE (as PCRE used to), but it + seems to me that giving a diagnostic is better. + +8. Change "alphameric" to the more common word "alphanumeric" in comments + and messages. + +9. Fix two occurrences of "backslash" in comments that should have been + "backspace". + +10. Remove two redundant lines of code that can never be obeyed (their function + was moved elsewhere). + +11. The program that makes PCRE's Unicode character property table had a bug + which caused it to generate incorrect table entries for sequences of + characters that have the same character type, but are in different scripts. + It amalgamated them into a single range, with the script of the first of + them. In other words, some characters were in the wrong script. There were + thirteen such cases, affecting characters in the following ranges: + + U+002b0 - U+002c1 + U+0060c - U+0060d + U+0061e - U+00612 + U+0064b - U+0065e + U+0074d - U+0076d + U+01800 - U+01805 + U+01d00 - U+01d77 + U+01d9b - U+01dbf + U+0200b - U+0200f + U+030fc - U+030fe + U+03260 - U+0327f + U+0fb46 - U+0fbb1 + U+10450 - U+1049d + +12. The -o option (show only the matching part of a line) for pcregrep was not + compatible with GNU grep in that, if there was more than one match in a + line, it showed only the first of them. It now behaves in the same way as + GNU grep. + +13. If the -o and -v options were combined for pcregrep, it printed a blank + line for every non-matching line. GNU grep prints nothing, and pcregrep now + does the same. The return code can be used to tell if there were any + non-matching lines. + +14. Added --file-offsets and --line-offsets to pcregrep. + +15. The pattern (?=something)(?R) was not being diagnosed as a potentially + infinitely looping recursion. The bug was that positive lookaheads were not + being skipped when checking for a possible empty match (negative lookaheads + and both kinds of lookbehind were skipped). + +16. Fixed two typos in the Windows-only code in pcregrep.c, and moved the + inclusion of to before rather than after the definition of + INVALID_FILE_ATTRIBUTES (patch from David Byron). + +17. Specifying a possessive quantifier with a specific limit for a Unicode + character property caused pcre_compile() to compile bad code, which led at + runtime to PCRE_ERROR_INTERNAL (-14). Examples of patterns that caused this + are: /\p{Zl}{2,3}+/8 and /\p{Cc}{2}+/8. It was the possessive "+" that + caused the error; without that there was no problem. + +18. Added --enable-pcregrep-libz and --enable-pcregrep-libbz2. + +19. Added --enable-pcretest-libreadline. + +20. In pcrecpp.cc, the variable 'count' was incremented twice in + RE::GlobalReplace(). As a result, the number of replacements returned was + double what it should be. I removed one of the increments, but Craig sent a + later patch that removed the other one (the right fix) and added unit tests + that check the return values (which was not done before). + +21. Several CMake things: + + (1) Arranged that, when cmake is used on Unix, the libraries end up with + the names libpcre and libpcreposix, not just pcre and pcreposix. + + (2) The above change means that pcretest and pcregrep are now correctly + linked with the newly-built libraries, not previously installed ones. + + (3) Added PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, PCRE_SUPPORT_LIBBZ2. + +22. In UTF-8 mode, with newline set to "any", a pattern such as .*a.*=.b.* + crashed when matching a string such as a\x{2029}b (note that \x{2029} is a + UTF-8 newline character). The key issue is that the pattern starts .*; + this means that the match must be either at the beginning, or after a + newline. The bug was in the code for advancing after a failed match and + checking that the new position followed a newline. It was not taking + account of UTF-8 characters correctly. + +23. PCRE was behaving differently from Perl in the way it recognized POSIX + character classes. PCRE was not treating the sequence [:...:] as a + character class unless the ... were all letters. Perl, however, seems to + allow any characters between [: and :], though of course it rejects as + unknown any "names" that contain non-letters, because all the known class + names consist only of letters. Thus, Perl gives an error for [[:1234:]], + for example, whereas PCRE did not - it did not recognize a POSIX character + class. This seemed a bit dangerous, so the code has been changed to be + closer to Perl. The behaviour is not identical to Perl, because PCRE will + diagnose an unknown class for, for example, [[:l\ower:]] where Perl will + treat it as [[:lower:]]. However, PCRE does now give "unknown" errors where + Perl does, and where it didn't before. + +24. Rewrite so as to remove the single use of %n from pcregrep because in some + Windows environments %n is disabled by default. + + +Version 7.4 21-Sep-07 +--------------------- + +1. Change 7.3/28 was implemented for classes by looking at the bitmap. This + means that a class such as [\s] counted as "explicit reference to CR or + LF". That isn't really right - the whole point of the change was to try to + help when there was an actual mention of one of the two characters. So now + the change happens only if \r or \n (or a literal CR or LF) character is + encountered. + +2. The 32-bit options word was also used for 6 internal flags, but the numbers + of both had grown to the point where there were only 3 bits left. + Fortunately, there was spare space in the data structure, and so I have + moved the internal flags into a new 16-bit field to free up more option + bits. + +3. The appearance of (?J) at the start of a pattern set the DUPNAMES option, + but did not set the internal JCHANGED flag - either of these is enough to + control the way the "get" function works - but the PCRE_INFO_JCHANGED + facility is supposed to tell if (?J) was ever used, so now (?J) at the + start sets both bits. + +4. Added options (at build time, compile time, exec time) to change \R from + matching any Unicode line ending sequence to just matching CR, LF, or CRLF. + +5. doc/pcresyntax.html was missing from the distribution. + +6. Put back the definition of PCRE_ERROR_NULLWSLIMIT, for backward + compatibility, even though it is no longer used. + +7. Added macro for snprintf to pcrecpp_unittest.cc and also for strtoll and + strtoull to pcrecpp.cc to select the available functions in WIN32 when the + windows.h file is present (where different names are used). [This was + reversed later after testing - see 16 below.] + +8. Changed all #include to #include "config.h". There were also + some further cases that I changed to "pcre.h". + +9. When pcregrep was used with the --colour option, it missed the line ending + sequence off the lines that it output. + +10. It was pointed out to me that arrays of string pointers cause lots of + relocations when a shared library is dynamically loaded. A technique of + using a single long string with a table of offsets can drastically reduce + these. I have refactored PCRE in four places to do this. The result is + dramatic: + + Originally: 290 + After changing UCP table: 187 + After changing error message table: 43 + After changing table of "verbs" 36 + After changing table of Posix names 22 + + Thanks to the folks working on Gregex for glib for this insight. + +11. --disable-stack-for-recursion caused compiling to fail unless -enable- + unicode-properties was also set. + +12. Updated the tests so that they work when \R is defaulted to ANYCRLF. + +13. Added checks for ANY and ANYCRLF to pcrecpp.cc where it previously + checked only for CRLF. + +14. Added casts to pcretest.c to avoid compiler warnings. + +15. Added Craig's patch to various pcrecpp modules to avoid compiler warnings. + +16. Added Craig's patch to remove the WINDOWS_H tests, that were not working, + and instead check for _strtoi64 explicitly, and avoid the use of snprintf() + entirely. This removes changes made in 7 above. + +17. The CMake files have been updated, and there is now more information about + building with CMake in the NON-UNIX-USE document. + + +Version 7.3 28-Aug-07 +--------------------- + + 1. In the rejigging of the build system that eventually resulted in 7.1, the + line "#include " was included in pcre_internal.h. The use of angle + brackets there is not right, since it causes compilers to look for an + installed pcre.h, not the version that is in the source that is being + compiled (which of course may be different). I have changed it back to: + + #include "pcre.h" + + I have a vague recollection that the change was concerned with compiling in + different directories, but in the new build system, that is taken care of + by the VPATH setting the Makefile. + + 2. The pattern .*$ when run in not-DOTALL UTF-8 mode with newline=any failed + when the subject happened to end in the byte 0x85 (e.g. if the last + character was \x{1ec5}). *Character* 0x85 is one of the "any" newline + characters but of course it shouldn't be taken as a newline when it is part + of another character. The bug was that, for an unlimited repeat of . in + not-DOTALL UTF-8 mode, PCRE was advancing by bytes rather than by + characters when looking for a newline. + + 3. A small performance improvement in the DOTALL UTF-8 mode .* case. + + 4. Debugging: adjusted the names of opcodes for different kinds of parentheses + in debug output. + + 5. Arrange to use "%I64d" instead of "%lld" and "%I64u" instead of "%llu" for + long printing in the pcrecpp unittest when running under MinGW. + + 6. ESC_K was left out of the EBCDIC table. + + 7. Change 7.0/38 introduced a new limit on the number of nested non-capturing + parentheses; I made it 1000, which seemed large enough. Unfortunately, the + limit also applies to "virtual nesting" when a pattern is recursive, and in + this case 1000 isn't so big. I have been able to remove this limit at the + expense of backing off one optimization in certain circumstances. Normally, + when pcre_exec() would call its internal match() function recursively and + immediately return the result unconditionally, it uses a "tail recursion" + feature to save stack. However, when a subpattern that can match an empty + string has an unlimited repetition quantifier, it no longer makes this + optimization. That gives it a stack frame in which to save the data for + checking that an empty string has been matched. Previously this was taken + from the 1000-entry workspace that had been reserved. So now there is no + explicit limit, but more stack is used. + + 8. Applied Daniel's patches to solve problems with the import/export magic + syntax that is required for Windows, and which was going wrong for the + pcreposix and pcrecpp parts of the library. These were overlooked when this + problem was solved for the main library. + + 9. There were some crude static tests to avoid integer overflow when computing + the size of patterns that contain repeated groups with explicit upper + limits. As the maximum quantifier is 65535, the maximum group length was + set at 30,000 so that the product of these two numbers did not overflow a + 32-bit integer. However, it turns out that people want to use groups that + are longer than 30,000 bytes (though not repeat them that many times). + Change 7.0/17 (the refactoring of the way the pattern size is computed) has + made it possible to implement the integer overflow checks in a much more + dynamic way, which I have now done. The artificial limitation on group + length has been removed - we now have only the limit on the total length of + the compiled pattern, which depends on the LINK_SIZE setting. + +10. Fixed a bug in the documentation for get/copy named substring when + duplicate names are permitted. If none of the named substrings are set, the + functions return PCRE_ERROR_NOSUBSTRING (7); the doc said they returned an + empty string. + +11. Because Perl interprets \Q...\E at a high level, and ignores orphan \E + instances, patterns such as [\Q\E] or [\E] or even [^\E] cause an error, + because the ] is interpreted as the first data character and the + terminating ] is not found. PCRE has been made compatible with Perl in this + regard. Previously, it interpreted [\Q\E] as an empty class, and [\E] could + cause memory overwriting. + +10. Like Perl, PCRE automatically breaks an unlimited repeat after an empty + string has been matched (to stop an infinite loop). It was not recognizing + a conditional subpattern that could match an empty string if that + subpattern was within another subpattern. For example, it looped when + trying to match (((?(1)X|))*) but it was OK with ((?(1)X|)*) where the + condition was not nested. This bug has been fixed. + +12. A pattern like \X?\d or \P{L}?\d in non-UTF-8 mode could cause a backtrack + past the start of the subject in the presence of bytes with the top bit + set, for example "\x8aBCD". + +13. Added Perl 5.10 experimental backtracking controls (*FAIL), (*F), (*PRUNE), + (*SKIP), (*THEN), (*COMMIT), and (*ACCEPT). + +14. Optimized (?!) to (*FAIL). + +15. Updated the test for a valid UTF-8 string to conform to the later RFC 3629. + This restricts code points to be within the range 0 to 0x10FFFF, excluding + the "low surrogate" sequence 0xD800 to 0xDFFF. Previously, PCRE allowed the + full range 0 to 0x7FFFFFFF, as defined by RFC 2279. Internally, it still + does: it's just the validity check that is more restrictive. + +16. Inserted checks for integer overflows during escape sequence (backslash) + processing, and also fixed erroneous offset values for syntax errors during + backslash processing. + +17. Fixed another case of looking too far back in non-UTF-8 mode (cf 12 above) + for patterns like [\PPP\x8a]{1,}\x80 with the subject "A\x80". + +18. An unterminated class in a pattern like (?1)\c[ with a "forward reference" + caused an overrun. + +19. A pattern like (?:[\PPa*]*){8,} which had an "extended class" (one with + something other than just ASCII characters) inside a group that had an + unlimited repeat caused a loop at compile time (while checking to see + whether the group could match an empty string). + +20. Debugging a pattern containing \p or \P could cause a crash. For example, + [\P{Any}] did so. (Error in the code for printing property names.) + +21. An orphan \E inside a character class could cause a crash. + +22. A repeated capturing bracket such as (A)? could cause a wild memory + reference during compilation. + +23. There are several functions in pcre_compile() that scan along a compiled + expression for various reasons (e.g. to see if it's fixed length for look + behind). There were bugs in these functions when a repeated \p or \P was + present in the pattern. These operators have additional parameters compared + with \d, etc, and these were not being taken into account when moving along + the compiled data. Specifically: + + (a) A item such as \p{Yi}{3} in a lookbehind was not treated as fixed + length. + + (b) An item such as \pL+ within a repeated group could cause crashes or + loops. + + (c) A pattern such as \p{Yi}+(\P{Yi}+)(?1) could give an incorrect + "reference to non-existent subpattern" error. + + (d) A pattern like (\P{Yi}{2}\277)? could loop at compile time. + +24. A repeated \S or \W in UTF-8 mode could give wrong answers when multibyte + characters were involved (for example /\S{2}/8g with "A\x{a3}BC"). + +25. Using pcregrep in multiline, inverted mode (-Mv) caused it to loop. + +26. Patterns such as [\P{Yi}A] which include \p or \P and just one other + character were causing crashes (broken optimization). + +27. Patterns such as (\P{Yi}*\277)* (group with possible zero repeat containing + \p or \P) caused a compile-time loop. + +28. More problems have arisen in unanchored patterns when CRLF is a valid line + break. For example, the unstudied pattern [\r\n]A does not match the string + "\r\nA" because change 7.0/46 below moves the current point on by two + characters after failing to match at the start. However, the pattern \nA + *does* match, because it doesn't start till \n, and if [\r\n]A is studied, + the same is true. There doesn't seem any very clean way out of this, but + what I have chosen to do makes the common cases work: PCRE now takes note + of whether there can be an explicit match for \r or \n anywhere in the + pattern, and if so, 7.0/46 no longer applies. As part of this change, + there's a new PCRE_INFO_HASCRORLF option for finding out whether a compiled + pattern has explicit CR or LF references. + +29. Added (*CR) etc for changing newline setting at start of pattern. + + +Version 7.2 19-Jun-07 +--------------------- + + 1. If the fr_FR locale cannot be found for test 3, try the "french" locale, + which is apparently normally available under Windows. + + 2. Re-jig the pcregrep tests with different newline settings in an attempt + to make them independent of the local environment's newline setting. + + 3. Add code to configure.ac to remove -g from the CFLAGS default settings. + + 4. Some of the "internals" tests were previously cut out when the link size + was not 2, because the output contained actual offsets. The recent new + "Z" feature of pcretest means that these can be cut out, making the tests + usable with all link sizes. + + 5. Implemented Stan Switzer's goto replacement for longjmp() when not using + stack recursion. This gives a massive performance boost under BSD, but just + a small improvement under Linux. However, it saves one field in the frame + in all cases. + + 6. Added more features from the forthcoming Perl 5.10: + + (a) (?-n) (where n is a string of digits) is a relative subroutine or + recursion call. It refers to the nth most recently opened parentheses. + + (b) (?+n) is also a relative subroutine call; it refers to the nth next + to be opened parentheses. + + (c) Conditions that refer to capturing parentheses can be specified + relatively, for example, (?(-2)... or (?(+3)... + + (d) \K resets the start of the current match so that everything before + is not part of it. + + (e) \k{name} is synonymous with \k and \k'name' (.NET compatible). + + (f) \g{name} is another synonym - part of Perl 5.10's unification of + reference syntax. + + (g) (?| introduces a group in which the numbering of parentheses in each + alternative starts with the same number. + + (h) \h, \H, \v, and \V match horizontal and vertical whitespace. + + 7. Added two new calls to pcre_fullinfo(): PCRE_INFO_OKPARTIAL and + PCRE_INFO_JCHANGED. + + 8. A pattern such as (.*(.)?)* caused pcre_exec() to fail by either not + terminating or by crashing. Diagnosed by Viktor Griph; it was in the code + for detecting groups that can match an empty string. + + 9. A pattern with a very large number of alternatives (more than several + hundred) was running out of internal workspace during the pre-compile + phase, where pcre_compile() figures out how much memory will be needed. A + bit of new cunning has reduced the workspace needed for groups with + alternatives. The 1000-alternative test pattern now uses 12 bytes of + workspace instead of running out of the 4096 that are available. + +10. Inserted some missing (unsigned int) casts to get rid of compiler warnings. + +11. Applied patch from Google to remove an optimization that didn't quite work. + The report of the bug said: + + pcrecpp::RE("a*").FullMatch("aaa") matches, while + pcrecpp::RE("a*?").FullMatch("aaa") does not, and + pcrecpp::RE("a*?\\z").FullMatch("aaa") does again. + +12. If \p or \P was used in non-UTF-8 mode on a character greater than 127 + it matched the wrong number of bytes. + + +Version 7.1 24-Apr-07 +--------------------- + + 1. Applied Bob Rossi and Daniel G's patches to convert the build system to one + that is more "standard", making use of automake and other Autotools. There + is some re-arrangement of the files and adjustment of comments consequent + on this. + + 2. Part of the patch fixed a problem with the pcregrep tests. The test of -r + for recursive directory scanning broke on some systems because the files + are not scanned in any specific order and on different systems the order + was different. A call to "sort" has been inserted into RunGrepTest for the + approprate test as a short-term fix. In the longer term there may be an + alternative. + + 3. I had an email from Eric Raymond about problems translating some of PCRE's + man pages to HTML (despite the fact that I distribute HTML pages, some + people do their own conversions for various reasons). The problems + concerned the use of low-level troff macros .br and .in. I have therefore + removed all such uses from the man pages (some were redundant, some could + be replaced by .nf/.fi pairs). The 132html script that I use to generate + HTML has been updated to handle .nf/.fi and to complain if it encounters + .br or .in. + + 4. Updated comments in configure.ac that get placed in config.h.in and also + arranged for config.h to be included in the distribution, with the name + config.h.generic, for the benefit of those who have to compile without + Autotools (compare pcre.h, which is now distributed as pcre.h.generic). + + 5. Updated the support (such as it is) for Virtual Pascal, thanks to Stefan + Weber: (1) pcre_internal.h was missing some function renames; (2) updated + makevp.bat for the current PCRE, using the additional files + makevp_c.txt, makevp_l.txt, and pcregexp.pas. + + 6. A Windows user reported a minor discrepancy with test 2, which turned out + to be caused by a trailing space on an input line that had got lost in his + copy. The trailing space was an accident, so I've just removed it. + + 7. Add -Wl,-R... flags in pcre-config.in for *BSD* systems, as I'm told + that is needed. + + 8. Mark ucp_table (in ucptable.h) and ucp_gentype (in pcre_ucp_searchfuncs.c) + as "const" (a) because they are and (b) because it helps the PHP + maintainers who have recently made a script to detect big data structures + in the php code that should be moved to the .rodata section. I remembered + to update Builducptable as well, so it won't revert if ucptable.h is ever + re-created. + + 9. Added some extra #ifdef SUPPORT_UTF8 conditionals into pcretest.c, + pcre_printint.src, pcre_compile.c, pcre_study.c, and pcre_tables.c, in + order to be able to cut out the UTF-8 tables in the latter when UTF-8 + support is not required. This saves 1.5-2K of code, which is important in + some applications. + + Later: more #ifdefs are needed in pcre_ord2utf8.c and pcre_valid_utf8.c + so as not to refer to the tables, even though these functions will never be + called when UTF-8 support is disabled. Otherwise there are problems with a + shared library. + +10. Fixed two bugs in the emulated memmove() function in pcre_internal.h: + + (a) It was defining its arguments as char * instead of void *. + + (b) It was assuming that all moves were upwards in memory; this was true + a long time ago when I wrote it, but is no longer the case. + + The emulated memove() is provided for those environments that have neither + memmove() nor bcopy(). I didn't think anyone used it these days, but that + is clearly not the case, as these two bugs were recently reported. + +11. The script PrepareRelease is now distributed: it calls 132html, CleanTxt, + and Detrail to create the HTML documentation, the .txt form of the man + pages, and it removes trailing spaces from listed files. It also creates + pcre.h.generic and config.h.generic from pcre.h and config.h. In the latter + case, it wraps all the #defines with #ifndefs. This script should be run + before "make dist". + +12. Fixed two fairly obscure bugs concerned with quantified caseless matching + with Unicode property support. + + (a) For a maximizing quantifier, if the two different cases of the + character were of different lengths in their UTF-8 codings (there are + some cases like this - I found 11), and the matching function had to + back up over a mixture of the two cases, it incorrectly assumed they + were both the same length. + + (b) When PCRE was configured to use the heap rather than the stack for + recursion during matching, it was not correctly preserving the data for + the other case of a UTF-8 character when checking ahead for a match + while processing a minimizing repeat. If the check also involved + matching a wide character, but failed, corruption could cause an + erroneous result when trying to check for a repeat of the original + character. + +13. Some tidying changes to the testing mechanism: + + (a) The RunTest script now detects the internal link size and whether there + is UTF-8 and UCP support by running ./pcretest -C instead of relying on + values substituted by "configure". (The RunGrepTest script already did + this for UTF-8.) The configure.ac script no longer substitutes the + relevant variables. + + (b) The debugging options /B and /D in pcretest show the compiled bytecode + with length and offset values. This means that the output is different + for different internal link sizes. Test 2 is skipped for link sizes + other than 2 because of this, bypassing the problem. Unfortunately, + there was also a test in test 3 (the locale tests) that used /B and + failed for link sizes other than 2. Rather than cut the whole test out, + I have added a new /Z option to pcretest that replaces the length and + offset values with spaces. This is now used to make test 3 independent + of link size. (Test 2 will be tidied up later.) + +14. If erroroffset was passed as NULL to pcre_compile, it provoked a + segmentation fault instead of returning the appropriate error message. + +15. In multiline mode when the newline sequence was set to "any", the pattern + ^$ would give a match between the \r and \n of a subject such as "A\r\nB". + This doesn't seem right; it now treats the CRLF combination as the line + ending, and so does not match in that case. It's only a pattern such as ^$ + that would hit this one: something like ^ABC$ would have failed after \r + and then tried again after \r\n. + +16. Changed the comparison command for RunGrepTest from "diff -u" to "diff -ub" + in an attempt to make files that differ only in their line terminators + compare equal. This works on Linux. + +17. Under certain error circumstances pcregrep might try to free random memory + as it exited. This is now fixed, thanks to valgrind. + +19. In pcretest, if the pattern /(?m)^$/g was matched against the string + "abc\r\n\r\n", it found an unwanted second match after the second \r. This + was because its rules for how to advance for /g after matching an empty + string at the end of a line did not allow for this case. They now check for + it specially. + +20. pcretest is supposed to handle patterns and data of any length, by + extending its buffers when necessary. It was getting this wrong when the + buffer for a data line had to be extended. + +21. Added PCRE_NEWLINE_ANYCRLF which is like ANY, but matches only CR, LF, or + CRLF as a newline sequence. + +22. Code for handling Unicode properties in pcre_dfa_exec() wasn't being cut + out by #ifdef SUPPORT_UCP. This did no harm, as it could never be used, but + I have nevertheless tidied it up. + +23. Added some casts to kill warnings from HP-UX ia64 compiler. + +24. Added a man page for pcre-config. + + +Version 7.0 19-Dec-06 +--------------------- + + 1. Fixed a signed/unsigned compiler warning in pcre_compile.c, shown up by + moving to gcc 4.1.1. + + 2. The -S option for pcretest uses setrlimit(); I had omitted to #include + sys/time.h, which is documented as needed for this function. It doesn't + seem to matter on Linux, but it showed up on some releases of OS X. + + 3. It seems that there are systems where bytes whose values are greater than + 127 match isprint() in the "C" locale. The "C" locale should be the + default when a C program starts up. In most systems, only ASCII printing + characters match isprint(). This difference caused the output from pcretest + to vary, making some of the tests fail. I have changed pcretest so that: + + (a) When it is outputting text in the compiled version of a pattern, bytes + other than 32-126 are always shown as hex escapes. + + (b) When it is outputting text that is a matched part of a subject string, + it does the same, unless a different locale has been set for the match + (using the /L modifier). In this case, it uses isprint() to decide. + + 4. Fixed a major bug that caused incorrect computation of the amount of memory + required for a compiled pattern when options that changed within the + pattern affected the logic of the preliminary scan that determines the + length. The relevant options are -x, and -i in UTF-8 mode. The result was + that the computed length was too small. The symptoms of this bug were + either the PCRE error "internal error: code overflow" from pcre_compile(), + or a glibc crash with a message such as "pcretest: free(): invalid next + size (fast)". Examples of patterns that provoked this bug (shown in + pcretest format) are: + + /(?-x: )/x + /(?x)(?-x: \s*#\s*)/ + /((?i)[\x{c0}])/8 + /(?i:[\x{c0}])/8 + + HOWEVER: Change 17 below makes this fix obsolete as the memory computation + is now done differently. + + 5. Applied patches from Google to: (a) add a QuoteMeta function to the C++ + wrapper classes; (b) implement a new function in the C++ scanner that is + more efficient than the old way of doing things because it avoids levels of + recursion in the regex matching; (c) add a paragraph to the documentation + for the FullMatch() function. + + 6. The escape sequence \n was being treated as whatever was defined as + "newline". Not only was this contrary to the documentation, which states + that \n is character 10 (hex 0A), but it also went horribly wrong when + "newline" was defined as CRLF. This has been fixed. + + 7. In pcre_dfa_exec.c the value of an unsigned integer (the variable called c) + was being set to -1 for the "end of line" case (supposedly a value that no + character can have). Though this value is never used (the check for end of + line is "zero bytes in current character"), it caused compiler complaints. + I've changed it to 0xffffffff. + + 8. In pcre_version.c, the version string was being built by a sequence of + C macros that, in the event of PCRE_PRERELEASE being defined as an empty + string (as it is for production releases) called a macro with an empty + argument. The C standard says the result of this is undefined. The gcc + compiler treats it as an empty string (which was what was wanted) but it is + reported that Visual C gives an error. The source has been hacked around to + avoid this problem. + + 9. On the advice of a Windows user, included and in Windows + builds of pcretest, and changed the call to _setmode() to use _O_BINARY + instead of 0x8000. Made all the #ifdefs test both _WIN32 and WIN32 (not all + of them did). + +10. Originally, pcretest opened its input and output without "b"; then I was + told that "b" was needed in some environments, so it was added for release + 5.0 to both the input and output. (It makes no difference on Unix-like + systems.) Later I was told that it is wrong for the input on Windows. I've + now abstracted the modes into two macros, to make it easier to fiddle with + them, and removed "b" from the input mode under Windows. + +11. Added pkgconfig support for the C++ wrapper library, libpcrecpp. + +12. Added -help and --help to pcretest as an official way of being reminded + of the options. + +13. Removed some redundant semicolons after macro calls in pcrecpparg.h.in + and pcrecpp.cc because they annoy compilers at high warning levels. + +14. A bit of tidying/refactoring in pcre_exec.c in the main bumpalong loop. + +15. Fixed an occurrence of == in configure.ac that should have been = (shell + scripts are not C programs :-) and which was not noticed because it works + on Linux. + +16. pcretest is supposed to handle any length of pattern and data line (as one + line or as a continued sequence of lines) by extending its input buffer if + necessary. This feature was broken for very long pattern lines, leading to + a string of junk being passed to pcre_compile() if the pattern was longer + than about 50K. + +17. I have done a major re-factoring of the way pcre_compile() computes the + amount of memory needed for a compiled pattern. Previously, there was code + that made a preliminary scan of the pattern in order to do this. That was + OK when PCRE was new, but as the facilities have expanded, it has become + harder and harder to keep it in step with the real compile phase, and there + have been a number of bugs (see for example, 4 above). I have now found a + cunning way of running the real compile function in a "fake" mode that + enables it to compute how much memory it would need, while actually only + ever using a few hundred bytes of working memory and without too many + tests of the mode. This should make future maintenance and development + easier. A side effect of this work is that the limit of 200 on the nesting + depth of parentheses has been removed (though this was never a serious + limitation, I suspect). However, there is a downside: pcre_compile() now + runs more slowly than before (30% or more, depending on the pattern). I + hope this isn't a big issue. There is no effect on runtime performance. + +18. Fixed a minor bug in pcretest: if a pattern line was not terminated by a + newline (only possible for the last line of a file) and it was a + pattern that set a locale (followed by /Lsomething), pcretest crashed. + +19. Added additional timing features to pcretest. (1) The -tm option now times + matching only, not compiling. (2) Both -t and -tm can be followed, as a + separate command line item, by a number that specifies the number of + repeats to use when timing. The default is 50000; this gives better + precision, but takes uncomfortably long for very large patterns. + +20. Extended pcre_study() to be more clever in cases where a branch of a + subpattern has no definite first character. For example, (a*|b*)[cd] would + previously give no result from pcre_study(). Now it recognizes that the + first character must be a, b, c, or d. + +21. There was an incorrect error "recursive call could loop indefinitely" if + a subpattern (or the entire pattern) that was being tested for matching an + empty string contained only one non-empty item after a nested subpattern. + For example, the pattern (?>\x{100}*)\d(?R) provoked this error + incorrectly, because the \d was being skipped in the check. + +22. The pcretest program now has a new pattern option /B and a command line + option -b, which is equivalent to adding /B to every pattern. This causes + it to show the compiled bytecode, without the additional information that + -d shows. The effect of -d is now the same as -b with -i (and similarly, /D + is the same as /B/I). + +23. A new optimization is now able automatically to treat some sequences such + as a*b as a*+b. More specifically, if something simple (such as a character + or a simple class like \d) has an unlimited quantifier, and is followed by + something that cannot possibly match the quantified thing, the quantifier + is automatically "possessified". + +24. A recursive reference to a subpattern whose number was greater than 39 + went wrong under certain circumstances in UTF-8 mode. This bug could also + have affected the operation of pcre_study(). + +25. Realized that a little bit of performance could be had by replacing + (c & 0xc0) == 0xc0 with c >= 0xc0 when processing UTF-8 characters. + +26. Timing data from pcretest is now shown to 4 decimal places instead of 3. + +27. Possessive quantifiers such as a++ were previously implemented by turning + them into atomic groups such as ($>a+). Now they have their own opcodes, + which improves performance. This includes the automatically created ones + from 23 above. + +28. A pattern such as (?=(\w+))\1: which simulates an atomic group using a + lookahead was broken if it was not anchored. PCRE was mistakenly expecting + the first matched character to be a colon. This applied both to named and + numbered groups. + +29. The ucpinternal.h header file was missing its idempotency #ifdef. + +30. I was sent a "project" file called libpcre.a.dev which I understand makes + building PCRE on Windows easier, so I have included it in the distribution. + +31. There is now a check in pcretest against a ridiculously large number being + returned by pcre_exec() or pcre_dfa_exec(). If this happens in a /g or /G + loop, the loop is abandoned. + +32. Forward references to subpatterns in conditions such as (?(2)...) where + subpattern 2 is defined later cause pcre_compile() to search forwards in + the pattern for the relevant set of parentheses. This search went wrong + when there were unescaped parentheses in a character class, parentheses + escaped with \Q...\E, or parentheses in a #-comment in /x mode. + +33. "Subroutine" calls and backreferences were previously restricted to + referencing subpatterns earlier in the regex. This restriction has now + been removed. + +34. Added a number of extra features that are going to be in Perl 5.10. On the + whole, these are just syntactic alternatives for features that PCRE had + previously implemented using the Python syntax or my own invention. The + other formats are all retained for compatibility. + + (a) Named groups can now be defined as (?...) or (?'name'...) as well + as (?P...). The new forms, as well as being in Perl 5.10, are + also .NET compatible. + + (b) A recursion or subroutine call to a named group can now be defined as + (?&name) as well as (?P>name). + + (c) A backreference to a named group can now be defined as \k or + \k'name' as well as (?P=name). The new forms, as well as being in Perl + 5.10, are also .NET compatible. + + (d) A conditional reference to a named group can now use the syntax + (?() or (?('name') as well as (?(name). + + (e) A "conditional group" of the form (?(DEFINE)...) can be used to define + groups (named and numbered) that are never evaluated inline, but can be + called as "subroutines" from elsewhere. In effect, the DEFINE condition + is always false. There may be only one alternative in such a group. + + (f) A test for recursion can be given as (?(R1).. or (?(R&name)... as well + as the simple (?(R). The condition is true only if the most recent + recursion is that of the given number or name. It does not search out + through the entire recursion stack. + + (g) The escape \gN or \g{N} has been added, where N is a positive or + negative number, specifying an absolute or relative reference. + +35. Tidied to get rid of some further signed/unsigned compiler warnings and + some "unreachable code" warnings. + +36. Updated the Unicode property tables to Unicode version 5.0.0. Amongst other + things, this adds five new scripts. + +37. Perl ignores orphaned \E escapes completely. PCRE now does the same. + There were also incompatibilities regarding the handling of \Q..\E inside + character classes, for example with patterns like [\Qa\E-\Qz\E] where the + hyphen was adjacent to \Q or \E. I hope I've cleared all this up now. + +38. Like Perl, PCRE detects when an indefinitely repeated parenthesized group + matches an empty string, and forcibly breaks the loop. There were bugs in + this code in non-simple cases. For a pattern such as ^(a()*)* matched + against aaaa the result was just "a" rather than "aaaa", for example. Two + separate and independent bugs (that affected different cases) have been + fixed. + +39. Refactored the code to abolish the use of different opcodes for small + capturing bracket numbers. This is a tidy that I avoided doing when I + removed the limit on the number of capturing brackets for 3.5 back in 2001. + The new approach is not only tidier, it makes it possible to reduce the + memory needed to fix the previous bug (38). + +40. Implemented PCRE_NEWLINE_ANY to recognize any of the Unicode newline + sequences (http://unicode.org/unicode/reports/tr18/) as "newline" when + processing dot, circumflex, or dollar metacharacters, or #-comments in /x + mode. + +41. Add \R to match any Unicode newline sequence, as suggested in the Unicode + report. + +42. Applied patch, originally from Ari Pollak, modified by Google, to allow + copy construction and assignment in the C++ wrapper. + +43. Updated pcregrep to support "--newline=any". In the process, I fixed a + couple of bugs that could have given wrong results in the "--newline=crlf" + case. + +44. Added a number of casts and did some reorganization of signed/unsigned int + variables following suggestions from Dair Grant. Also renamed the variable + "this" as "item" because it is a C++ keyword. + +45. Arranged for dftables to add + + #include "pcre_internal.h" + + to pcre_chartables.c because without it, gcc 4.x may remove the array + definition from the final binary if PCRE is built into a static library and + dead code stripping is activated. + +46. For an unanchored pattern, if a match attempt fails at the start of a + newline sequence, and the newline setting is CRLF or ANY, and the next two + characters are CRLF, advance by two characters instead of one. + + +Version 6.7 04-Jul-06 +--------------------- + + 1. In order to handle tests when input lines are enormously long, pcretest has + been re-factored so that it automatically extends its buffers when + necessary. The code is crude, but this _is_ just a test program. The + default size has been increased from 32K to 50K. + + 2. The code in pcre_study() was using the value of the re argument before + testing it for NULL. (Of course, in any sensible call of the function, it + won't be NULL.) + + 3. The memmove() emulation function in pcre_internal.h, which is used on + systems that lack both memmove() and bcopy() - that is, hardly ever - + was missing a "static" storage class specifier. + + 4. When UTF-8 mode was not set, PCRE looped when compiling certain patterns + containing an extended class (one that cannot be represented by a bitmap + because it contains high-valued characters or Unicode property items, e.g. + [\pZ]). Almost always one would set UTF-8 mode when processing such a + pattern, but PCRE should not loop if you do not (it no longer does). + [Detail: two cases were found: (a) a repeated subpattern containing an + extended class; (b) a recursive reference to a subpattern that followed a + previous extended class. It wasn't skipping over the extended class + correctly when UTF-8 mode was not set.] + + 5. A negated single-character class was not being recognized as fixed-length + in lookbehind assertions such as (?<=[^f]), leading to an incorrect + compile error "lookbehind assertion is not fixed length". + + 6. The RunPerlTest auxiliary script was showing an unexpected difference + between PCRE and Perl for UTF-8 tests. It turns out that it is hard to + write a Perl script that can interpret lines of an input file either as + byte characters or as UTF-8, which is what "perltest" was being required to + do for the non-UTF-8 and UTF-8 tests, respectively. Essentially what you + can't do is switch easily at run time between having the "use utf8;" pragma + or not. In the end, I fudged it by using the RunPerlTest script to insert + "use utf8;" explicitly for the UTF-8 tests. + + 7. In multiline (/m) mode, PCRE was matching ^ after a terminating newline at + the end of the subject string, contrary to the documentation and to what + Perl does. This was true of both matching functions. Now it matches only at + the start of the subject and immediately after *internal* newlines. + + 8. A call of pcre_fullinfo() from pcretest to get the option bits was passing + a pointer to an int instead of a pointer to an unsigned long int. This + caused problems on 64-bit systems. + + 9. Applied a patch from the folks at Google to pcrecpp.cc, to fix "another + instance of the 'standard' template library not being so standard". + +10. There was no check on the number of named subpatterns nor the maximum + length of a subpattern name. The product of these values is used to compute + the size of the memory block for a compiled pattern. By supplying a very + long subpattern name and a large number of named subpatterns, the size + computation could be caused to overflow. This is now prevented by limiting + the length of names to 32 characters, and the number of named subpatterns + to 10,000. + +11. Subpatterns that are repeated with specific counts have to be replicated in + the compiled pattern. The size of memory for this was computed from the + length of the subpattern and the repeat count. The latter is limited to + 65535, but there was no limit on the former, meaning that integer overflow + could in principle occur. The compiled length of a repeated subpattern is + now limited to 30,000 bytes in order to prevent this. + +12. Added the optional facility to have named substrings with the same name. + +13. Added the ability to use a named substring as a condition, using the + Python syntax: (?(name)yes|no). This overloads (?(R)... and names that + are numbers (not recommended). Forward references are permitted. + +14. Added forward references in named backreferences (if you see what I mean). + +15. In UTF-8 mode, with the PCRE_DOTALL option set, a quantified dot in the + pattern could run off the end of the subject. For example, the pattern + "(?s)(.{1,5})"8 did this with the subject "ab". + +16. If PCRE_DOTALL or PCRE_MULTILINE were set, pcre_dfa_exec() behaved as if + PCRE_CASELESS was set when matching characters that were quantified with ? + or *. + +17. A character class other than a single negated character that had a minimum + but no maximum quantifier - for example [ab]{6,} - was not handled + correctly by pce_dfa_exec(). It would match only one character. + +18. A valid (though odd) pattern that looked like a POSIX character + class but used an invalid character after [ (for example [[,abc,]]) caused + pcre_compile() to give the error "Failed: internal error: code overflow" or + in some cases to crash with a glibc free() error. This could even happen if + the pattern terminated after [[ but there just happened to be a sequence of + letters, a binary zero, and a closing ] in the memory that followed. + +19. Perl's treatment of octal escapes in the range \400 to \777 has changed + over the years. Originally (before any Unicode support), just the bottom 8 + bits were taken. Thus, for example, \500 really meant \100. Nowadays the + output from "man perlunicode" includes this: + + The regular expression compiler produces polymorphic opcodes. That + is, the pattern adapts to the data and automatically switches to + the Unicode character scheme when presented with Unicode data--or + instead uses a traditional byte scheme when presented with byte + data. + + Sadly, a wide octal escape does not cause a switch, and in a string with + no other multibyte characters, these octal escapes are treated as before. + Thus, in Perl, the pattern /\500/ actually matches \100 but the pattern + /\500|\x{1ff}/ matches \500 or \777 because the whole thing is treated as a + Unicode string. + + I have not perpetrated such confusion in PCRE. Up till now, it took just + the bottom 8 bits, as in old Perl. I have now made octal escapes with + values greater than \377 illegal in non-UTF-8 mode. In UTF-8 mode they + translate to the appropriate multibyte character. + +29. Applied some refactoring to reduce the number of warnings from Microsoft + and Borland compilers. This has included removing the fudge introduced + seven years ago for the OS/2 compiler (see 2.02/2 below) because it caused + a warning about an unused variable. + +21. PCRE has not included VT (character 0x0b) in the set of whitespace + characters since release 4.0, because Perl (from release 5.004) does not. + [Or at least, is documented not to: some releases seem to be in conflict + with the documentation.] However, when a pattern was studied with + pcre_study() and all its branches started with \s, PCRE still included VT + as a possible starting character. Of course, this did no harm; it just + caused an unnecessary match attempt. + +22. Removed a now-redundant internal flag bit that recorded the fact that case + dependency changed within the pattern. This was once needed for "required + byte" processing, but is no longer used. This recovers a now-scarce options + bit. Also moved the least significant internal flag bit to the most- + significant bit of the word, which was not previously used (hangover from + the days when it was an int rather than a uint) to free up another bit for + the future. + +23. Added support for CRLF line endings as well as CR and LF. As well as the + default being selectable at build time, it can now be changed at runtime + via the PCRE_NEWLINE_xxx flags. There are now options for pcregrep to + specify that it is scanning data with non-default line endings. + +24. Changed the definition of CXXLINK to make it agree with the definition of + LINK in the Makefile, by replacing LDFLAGS to CXXFLAGS. + +25. Applied Ian Taylor's patches to avoid using another stack frame for tail + recursions. This makes a big different to stack usage for some patterns. + +26. If a subpattern containing a named recursion or subroutine reference such + as (?P>B) was quantified, for example (xxx(?P>B)){3}, the calculation of + the space required for the compiled pattern went wrong and gave too small a + value. Depending on the environment, this could lead to "Failed: internal + error: code overflow at offset 49" or "glibc detected double free or + corruption" errors. + +27. Applied patches from Google (a) to support the new newline modes and (b) to + advance over multibyte UTF-8 characters in GlobalReplace. + +28. Change free() to pcre_free() in pcredemo.c. Apparently this makes a + difference for some implementation of PCRE in some Windows version. + +29. Added some extra testing facilities to pcretest: + + \q in a data line sets the "match limit" value + \Q in a data line sets the "match recursion limt" value + -S sets the stack size, where is in megabytes + + The -S option isn't available for Windows. + + +Version 6.6 06-Feb-06 +--------------------- + + 1. Change 16(a) for 6.5 broke things, because PCRE_DATA_SCOPE was not defined + in pcreposix.h. I have copied the definition from pcre.h. + + 2. Change 25 for 6.5 broke compilation in a build directory out-of-tree + because pcre.h is no longer a built file. + + 3. Added Jeff Friedl's additional debugging patches to pcregrep. These are + not normally included in the compiled code. + + +Version 6.5 01-Feb-06 +--------------------- + + 1. When using the partial match feature with pcre_dfa_exec(), it was not + anchoring the second and subsequent partial matches at the new starting + point. This could lead to incorrect results. For example, with the pattern + /1234/, partially matching against "123" and then "a4" gave a match. + + 2. Changes to pcregrep: + + (a) All non-match returns from pcre_exec() were being treated as failures + to match the line. Now, unless the error is PCRE_ERROR_NOMATCH, an + error message is output. Some extra information is given for the + PCRE_ERROR_MATCHLIMIT and PCRE_ERROR_RECURSIONLIMIT errors, which are + probably the only errors that are likely to be caused by users (by + specifying a regex that has nested indefinite repeats, for instance). + If there are more than 20 of these errors, pcregrep is abandoned. + + (b) A binary zero was treated as data while matching, but terminated the + output line if it was written out. This has been fixed: binary zeroes + are now no different to any other data bytes. + + (c) Whichever of the LC_ALL or LC_CTYPE environment variables is set is + used to set a locale for matching. The --locale=xxxx long option has + been added (no short equivalent) to specify a locale explicitly on the + pcregrep command, overriding the environment variables. + + (d) When -B was used with -n, some line numbers in the output were one less + than they should have been. + + (e) Added the -o (--only-matching) option. + + (f) If -A or -C was used with -c (count only), some lines of context were + accidentally printed for the final match. + + (g) Added the -H (--with-filename) option. + + (h) The combination of options -rh failed to suppress file names for files + that were found from directory arguments. + + (i) Added the -D (--devices) and -d (--directories) options. + + (j) Added the -F (--fixed-strings) option. + + (k) Allow "-" to be used as a file name for -f as well as for a data file. + + (l) Added the --colo(u)r option. + + (m) Added Jeffrey Friedl's -S testing option, but within #ifdefs so that it + is not present by default. + + 3. A nasty bug was discovered in the handling of recursive patterns, that is, + items such as (?R) or (?1), when the recursion could match a number of + alternatives. If it matched one of the alternatives, but subsequently, + outside the recursion, there was a failure, the code tried to back up into + the recursion. However, because of the way PCRE is implemented, this is not + possible, and the result was an incorrect result from the match. + + In order to prevent this happening, the specification of recursion has + been changed so that all such subpatterns are automatically treated as + atomic groups. Thus, for example, (?R) is treated as if it were (?>(?R)). + + 4. I had overlooked the fact that, in some locales, there are characters for + which isalpha() is true but neither isupper() nor islower() are true. In + the fr_FR locale, for instance, the \xAA and \xBA characters (ordmasculine + and ordfeminine) are like this. This affected the treatment of \w and \W + when they appeared in character classes, but not when they appeared outside + a character class. The bit map for "word" characters is now created + separately from the results of isalnum() instead of just taking it from the + upper, lower, and digit maps. (Plus the underscore character, of course.) + + 5. The above bug also affected the handling of POSIX character classes such as + [[:alpha:]] and [[:alnum:]]. These do not have their own bit maps in PCRE's + permanent tables. Instead, the bit maps for such a class were previously + created as the appropriate unions of the upper, lower, and digit bitmaps. + Now they are created by subtraction from the [[:word:]] class, which has + its own bitmap. + + 6. The [[:blank:]] character class matches horizontal, but not vertical space. + It is created by subtracting the vertical space characters (\x09, \x0a, + \x0b, \x0c) from the [[:space:]] bitmap. Previously, however, the + subtraction was done in the overall bitmap for a character class, meaning + that a class such as [\x0c[:blank:]] was incorrect because \x0c would not + be recognized. This bug has been fixed. + + 7. Patches from the folks at Google: + + (a) pcrecpp.cc: "to handle a corner case that may or may not happen in + real life, but is still worth protecting against". + + (b) pcrecpp.cc: "corrects a bug when negative radixes are used with + regular expressions". + + (c) pcre_scanner.cc: avoid use of std::count() because not all systems + have it. + + (d) Split off pcrecpparg.h from pcrecpp.h and had the former built by + "configure" and the latter not, in order to fix a problem somebody had + with compiling the Arg class on HP-UX. + + (e) Improve the error-handling of the C++ wrapper a little bit. + + (f) New tests for checking recursion limiting. + + 8. The pcre_memmove() function, which is used only if the environment does not + have a standard memmove() function (and is therefore rarely compiled), + contained two bugs: (a) use of int instead of size_t, and (b) it was not + returning a result (though PCRE never actually uses the result). + + 9. In the POSIX regexec() interface, if nmatch is specified as a ridiculously + large number - greater than INT_MAX/(3*sizeof(int)) - REG_ESPACE is + returned instead of calling malloc() with an overflowing number that would + most likely cause subsequent chaos. + +10. The debugging option of pcretest was not showing the NO_AUTO_CAPTURE flag. + +11. The POSIX flag REG_NOSUB is now supported. When a pattern that was compiled + with this option is matched, the nmatch and pmatch options of regexec() are + ignored. + +12. Added REG_UTF8 to the POSIX interface. This is not defined by POSIX, but is + provided in case anyone wants to the the POSIX interface with UTF-8 + strings. + +13. Added CXXLDFLAGS to the Makefile parameters to provide settings only on the + C++ linking (needed for some HP-UX environments). + +14. Avoid compiler warnings in get_ucpname() when compiled without UCP support + (unused parameter) and in the pcre_printint() function (omitted "default" + switch label when the default is to do nothing). + +15. Added some code to make it possible, when PCRE is compiled as a C++ + library, to replace subject pointers for pcre_exec() with a smart pointer + class, thus making it possible to process discontinuous strings. + +16. The two macros PCRE_EXPORT and PCRE_DATA_SCOPE are confusing, and perform + much the same function. They were added by different people who were trying + to make PCRE easy to compile on non-Unix systems. It has been suggested + that PCRE_EXPORT be abolished now that there is more automatic apparatus + for compiling on Windows systems. I have therefore replaced it with + PCRE_DATA_SCOPE. This is set automatically for Windows; if not set it + defaults to "extern" for C or "extern C" for C++, which works fine on + Unix-like systems. It is now possible to override the value of PCRE_DATA_ + SCOPE with something explicit in config.h. In addition: + + (a) pcreposix.h still had just "extern" instead of either of these macros; + I have replaced it with PCRE_DATA_SCOPE. + + (b) Functions such as _pcre_xclass(), which are internal to the library, + but external in the C sense, all had PCRE_EXPORT in their definitions. + This is apparently wrong for the Windows case, so I have removed it. + (It makes no difference on Unix-like systems.) + +17. Added a new limit, MATCH_LIMIT_RECURSION, which limits the depth of nesting + of recursive calls to match(). This is different to MATCH_LIMIT because + that limits the total number of calls to match(), not all of which increase + the depth of recursion. Limiting the recursion depth limits the amount of + stack (or heap if NO_RECURSE is set) that is used. The default can be set + when PCRE is compiled, and changed at run time. A patch from Google adds + this functionality to the C++ interface. + +18. Changes to the handling of Unicode character properties: + + (a) Updated the table to Unicode 4.1.0. + + (b) Recognize characters that are not in the table as "Cn" (undefined). + + (c) I revised the way the table is implemented to a much improved format + which includes recognition of ranges. It now supports the ranges that + are defined in UnicodeData.txt, and it also amalgamates other + characters into ranges. This has reduced the number of entries in the + table from around 16,000 to around 3,000, thus reducing its size + considerably. I realized I did not need to use a tree structure after + all - a binary chop search is just as efficient. Having reduced the + number of entries, I extended their size from 6 bytes to 8 bytes to + allow for more data. + + (d) Added support for Unicode script names via properties such as \p{Han}. + +19. In UTF-8 mode, a backslash followed by a non-Ascii character was not + matching that character. + +20. When matching a repeated Unicode property with a minimum greater than zero, + (for example \pL{2,}), PCRE could look past the end of the subject if it + reached it while seeking the minimum number of characters. This could + happen only if some of the characters were more than one byte long, because + there is a check for at least the minimum number of bytes. + +21. Refactored the implementation of \p and \P so as to be more general, to + allow for more different types of property in future. This has changed the + compiled form incompatibly. Anybody with saved compiled patterns that use + \p or \P will have to recompile them. + +22. Added "Any" and "L&" to the supported property types. + +23. Recognize \x{...} as a code point specifier, even when not in UTF-8 mode, + but give a compile time error if the value is greater than 0xff. + +24. The man pages for pcrepartial, pcreprecompile, and pcre_compile2 were + accidentally not being installed or uninstalled. + +25. The pcre.h file was built from pcre.h.in, but the only changes that were + made were to insert the current release number. This seemed silly, because + it made things harder for people building PCRE on systems that don't run + "configure". I have turned pcre.h into a distributed file, no longer built + by "configure", with the version identification directly included. There is + no longer a pcre.h.in file. + + However, this change necessitated a change to the pcre-config script as + well. It is built from pcre-config.in, and one of the substitutions was the + release number. I have updated configure.ac so that ./configure now finds + the release number by grepping pcre.h. + +26. Added the ability to run the tests under valgrind. + + +Version 6.4 05-Sep-05 +--------------------- + + 1. Change 6.0/10/(l) to pcregrep introduced a bug that caused separator lines + "--" to be printed when multiple files were scanned, even when none of the + -A, -B, or -C options were used. This is not compatible with Gnu grep, so I + consider it to be a bug, and have restored the previous behaviour. + + 2. A couple of code tidies to get rid of compiler warnings. + + 3. The pcretest program used to cheat by referring to symbols in the library + whose names begin with _pcre_. These are internal symbols that are not + really supposed to be visible externally, and in some environments it is + possible to suppress them. The cheating is now confined to including + certain files from the library's source, which is a bit cleaner. + + 4. Renamed pcre.in as pcre.h.in to go with pcrecpp.h.in; it also makes the + file's purpose clearer. + + 5. Reorganized pcre_ucp_findchar(). + + +Version 6.3 15-Aug-05 +--------------------- + + 1. The file libpcre.pc.in did not have general read permission in the tarball. + + 2. There were some problems when building without C++ support: + + (a) If C++ support was not built, "make install" and "make test" still + tried to test it. + + (b) There were problems when the value of CXX was explicitly set. Some + changes have been made to try to fix these, and ... + + (c) --disable-cpp can now be used to explicitly disable C++ support. + + (d) The use of @CPP_OBJ@ directly caused a blank line preceded by a + backslash in a target when C++ was disabled. This confuses some + versions of "make", apparently. Using an intermediate variable solves + this. (Same for CPP_LOBJ.) + + 3. $(LINK_FOR_BUILD) now includes $(CFLAGS_FOR_BUILD) and $(LINK) + (non-Windows) now includes $(CFLAGS) because these flags are sometimes + necessary on certain architectures. + + 4. Added a setting of -export-symbols-regex to the link command to remove + those symbols that are exported in the C sense, but actually are local + within the library, and not documented. Their names all begin with + "_pcre_". This is not a perfect job, because (a) we have to except some + symbols that pcretest ("illegally") uses, and (b) the facility isn't always + available (and never for static libraries). I have made a note to try to + find a way round (a) in the future. + + +Version 6.2 01-Aug-05 +--------------------- + + 1. There was no test for integer overflow of quantifier values. A construction + such as {1111111111111111} would give undefined results. What is worse, if + a minimum quantifier for a parenthesized subpattern overflowed and became + negative, the calculation of the memory size went wrong. This could have + led to memory overwriting. + + 2. Building PCRE using VPATH was broken. Hopefully it is now fixed. + + 3. Added "b" to the 2nd argument of fopen() in dftables.c, for non-Unix-like + operating environments where this matters. + + 4. Applied Giuseppe Maxia's patch to add additional features for controlling + PCRE options from within the C++ wrapper. + + 5. Named capturing subpatterns were not being correctly counted when a pattern + was compiled. This caused two problems: (a) If there were more than 100 + such subpatterns, the calculation of the memory needed for the whole + compiled pattern went wrong, leading to an overflow error. (b) Numerical + back references of the form \12, where the number was greater than 9, were + not recognized as back references, even though there were sufficient + previous subpatterns. + + 6. Two minor patches to pcrecpp.cc in order to allow it to compile on older + versions of gcc, e.g. 2.95.4. + + +Version 6.1 21-Jun-05 +--------------------- + + 1. There was one reference to the variable "posix" in pcretest.c that was not + surrounded by "#if !defined NOPOSIX". + + 2. Make it possible to compile pcretest without DFA support, UTF8 support, or + the cross-check on the old pcre_info() function, for the benefit of the + cut-down version of PCRE that is currently imported into Exim. + + 3. A (silly) pattern starting with (?i)(?-i) caused an internal space + allocation error. I've done the easy fix, which wastes 2 bytes for sensible + patterns that start (?i) but I don't think that matters. The use of (?i) is + just an example; this all applies to the other options as well. + + 4. Since libtool seems to echo the compile commands it is issuing, the output + from "make" can be reduced a bit by putting "@" in front of each libtool + compile command. + + 5. Patch from the folks at Google for configure.in to be a bit more thorough + in checking for a suitable C++ installation before trying to compile the + C++ stuff. This should fix a reported problem when a compiler was present, + but no suitable headers. + + 6. The man pages all had just "PCRE" as their title. I have changed them to + be the relevant file name. I have also arranged that these names are + retained in the file doc/pcre.txt, which is a concatenation in text format + of all the man pages except the little individual ones for each function. + + 7. The NON-UNIX-USE file had not been updated for the different set of source + files that come with release 6. I also added a few comments about the C++ + wrapper. + + +Version 6.0 07-Jun-05 +--------------------- + + 1. Some minor internal re-organization to help with my DFA experiments. + + 2. Some missing #ifdef SUPPORT_UCP conditionals in pcretest and printint that + didn't matter for the library itself when fully configured, but did matter + when compiling without UCP support, or within Exim, where the ucp files are + not imported. + + 3. Refactoring of the library code to split up the various functions into + different source modules. The addition of the new DFA matching code (see + below) to a single monolithic source would have made it really too + unwieldy, quite apart from causing all the code to be include in a + statically linked application, when only some functions are used. This is + relevant even without the DFA addition now that patterns can be compiled in + one application and matched in another. + + The downside of splitting up is that there have to be some external + functions and data tables that are used internally in different modules of + the library but which are not part of the API. These have all had their + names changed to start with "_pcre_" so that they are unlikely to clash + with other external names. + + 4. Added an alternate matching function, pcre_dfa_exec(), which matches using + a different (DFA) algorithm. Although it is slower than the original + function, it does have some advantages for certain types of matching + problem. + + 5. Upgrades to pcretest in order to test the features of pcre_dfa_exec(), + including restarting after a partial match. + + 6. A patch for pcregrep that defines INVALID_FILE_ATTRIBUTES if it is not + defined when compiling for Windows was sent to me. I have put it into the + code, though I have no means of testing or verifying it. + + 7. Added the pcre_refcount() auxiliary function. + + 8. Added the PCRE_FIRSTLINE option. This constrains an unanchored pattern to + match before or at the first newline in the subject string. In pcretest, + the /f option on a pattern can be used to set this. + + 9. A repeated \w when used in UTF-8 mode with characters greater than 256 + would behave wrongly. This has been present in PCRE since release 4.0. + +10. A number of changes to the pcregrep command: + + (a) Refactored how -x works; insert ^(...)$ instead of setting + PCRE_ANCHORED and checking the length, in preparation for adding + something similar for -w. + + (b) Added the -w (match as a word) option. + + (c) Refactored the way lines are read and buffered so as to have more + than one at a time available. + + (d) Implemented a pcregrep test script. + + (e) Added the -M (multiline match) option. This allows patterns to match + over several lines of the subject. The buffering ensures that at least + 8K, or the rest of the document (whichever is the shorter) is available + for matching (and similarly the previous 8K for lookbehind assertions). + + (f) Changed the --help output so that it now says + + -w, --word-regex(p) + + instead of two lines, one with "regex" and the other with "regexp" + because that confused at least one person since the short forms are the + same. (This required a bit of code, as the output is generated + automatically from a table. It wasn't just a text change.) + + (g) -- can be used to terminate pcregrep options if the next thing isn't an + option but starts with a hyphen. Could be a pattern or a path name + starting with a hyphen, for instance. + + (h) "-" can be given as a file name to represent stdin. + + (i) When file names are being printed, "(standard input)" is used for + the standard input, for compatibility with GNU grep. Previously + "" was used. + + (j) The option --label=xxx can be used to supply a name to be used for + stdin when file names are being printed. There is no short form. + + (k) Re-factored the options decoding logic because we are going to add + two more options that take data. Such options can now be given in four + different ways, e.g. "-fname", "-f name", "--file=name", "--file name". + + (l) Added the -A, -B, and -C options for requesting that lines of context + around matches be printed. + + (m) Added the -L option to print the names of files that do not contain + any matching lines, that is, the complement of -l. + + (n) The return code is 2 if any file cannot be opened, but pcregrep does + continue to scan other files. + + (o) The -s option was incorrectly implemented. For compatibility with other + greps, it now suppresses the error message for a non-existent or non- + accessible file (but not the return code). There is a new option called + -q that suppresses the output of matching lines, which was what -s was + previously doing. + + (p) Added --include and --exclude options to specify files for inclusion + and exclusion when recursing. + +11. The Makefile was not using the Autoconf-supported LDFLAGS macro properly. + Hopefully, it now does. + +12. Missing cast in pcre_study(). + +13. Added an "uninstall" target to the makefile. + +14. Replaced "extern" in the function prototypes in Makefile.in with + "PCRE_DATA_SCOPE", which defaults to 'extern' or 'extern "C"' in the Unix + world, but is set differently for Windows. + +15. Added a second compiling function called pcre_compile2(). The only + difference is that it has an extra argument, which is a pointer to an + integer error code. When there is a compile-time failure, this is set + non-zero, in addition to the error test pointer being set to point to an + error message. The new argument may be NULL if no error number is required + (but then you may as well call pcre_compile(), which is now just a + wrapper). This facility is provided because some applications need a + numeric error indication, but it has also enabled me to tidy up the way + compile-time errors are handled in the POSIX wrapper. + +16. Added VPATH=.libs to the makefile; this should help when building with one + prefix path and installing with another. (Or so I'm told by someone who + knows more about this stuff than I do.) + +17. Added a new option, REG_DOTALL, to the POSIX function regcomp(). This + passes PCRE_DOTALL to the pcre_compile() function, making the "." character + match everything, including newlines. This is not POSIX-compatible, but + somebody wanted the feature. From pcretest it can be activated by using + both the P and the s flags. + +18. AC_PROG_LIBTOOL appeared twice in Makefile.in. Removed one. + +19. libpcre.pc was being incorrectly installed as executable. + +20. A couple of places in pcretest check for end-of-line by looking for '\n'; + it now also looks for '\r' so that it will work unmodified on Windows. + +21. Added Google's contributed C++ wrapper to the distribution. + +22. Added some untidy missing memory free() calls in pcretest, to keep + Electric Fence happy when testing. + + + +Version 5.0 13-Sep-04 +--------------------- + + 1. Internal change: literal characters are no longer packed up into items + containing multiple characters in a single byte-string. Each character + is now matched using a separate opcode. However, there may be more than one + byte in the character in UTF-8 mode. + + 2. The pcre_callout_block structure has two new fields: pattern_position and + next_item_length. These contain the offset in the pattern to the next match + item, and its length, respectively. + + 3. The PCRE_AUTO_CALLOUT option for pcre_compile() requests the automatic + insertion of callouts before each pattern item. Added the /C option to + pcretest to make use of this. + + 4. On the advice of a Windows user, the lines + + #if defined(_WIN32) || defined(WIN32) + _setmode( _fileno( stdout ), 0x8000 ); + #endif /* defined(_WIN32) || defined(WIN32) */ + + have been added to the source of pcretest. This apparently does useful + magic in relation to line terminators. + + 5. Changed "r" and "w" in the calls to fopen() in pcretest to "rb" and "wb" + for the benefit of those environments where the "b" makes a difference. + + 6. The icc compiler has the same options as gcc, but "configure" doesn't seem + to know about it. I have put a hack into configure.in that adds in code + to set GCC=yes if CC=icc. This seems to end up at a point in the + generated configure script that is early enough to affect the setting of + compiler options, which is what is needed, but I have no means of testing + whether it really works. (The user who reported this had patched the + generated configure script, which of course I cannot do.) + + LATER: After change 22 below (new libtool files), the configure script + seems to know about icc (and also ecc). Therefore, I have commented out + this hack in configure.in. + + 7. Added support for pkg-config (2 patches were sent in). + + 8. Negated POSIX character classes that used a combination of internal tables + were completely broken. These were [[:^alpha:]], [[:^alnum:]], and + [[:^ascii]]. Typically, they would match almost any characters. The other + POSIX classes were not broken in this way. + + 9. Matching the pattern "\b.*?" against "ab cd", starting at offset 1, failed + to find the match, as PCRE was deluded into thinking that the match had to + start at the start point or following a newline. The same bug applied to + patterns with negative forward assertions or any backward assertions + preceding ".*" at the start, unless the pattern required a fixed first + character. This was a failing pattern: "(?!.bcd).*". The bug is now fixed. + +10. In UTF-8 mode, when moving forwards in the subject after a failed match + starting at the last subject character, bytes beyond the end of the subject + string were read. + +11. Renamed the variable "class" as "classbits" to make life easier for C++ + users. (Previously there was a macro definition, but it apparently wasn't + enough.) + +12. Added the new field "tables" to the extra data so that tables can be passed + in at exec time, or the internal tables can be re-selected. This allows + a compiled regex to be saved and re-used at a later time by a different + program that might have everything at different addresses. + +13. Modified the pcre-config script so that, when run on Solaris, it shows a + -R library as well as a -L library. + +14. The debugging options of pcretest (-d on the command line or D on a + pattern) showed incorrect output for anything following an extended class + that contained multibyte characters and which was followed by a quantifier. + +15. Added optional support for general category Unicode character properties + via the \p, \P, and \X escapes. Unicode property support implies UTF-8 + support. It adds about 90K to the size of the library. The meanings of the + inbuilt class escapes such as \d and \s have NOT been changed. + +16. Updated pcredemo.c to include calls to free() to release the memory for the + compiled pattern. + +17. The generated file chartables.c was being created in the source directory + instead of in the building directory. This caused the build to fail if the + source directory was different from the building directory, and was + read-only. + +18. Added some sample Win commands from Mark Tetrode into the NON-UNIX-USE + file. No doubt somebody will tell me if they don't make sense... Also added + Dan Mooney's comments about building on OpenVMS. + +19. Added support for partial matching via the PCRE_PARTIAL option for + pcre_exec() and the \P data escape in pcretest. + +20. Extended pcretest with 3 new pattern features: + + (i) A pattern option of the form ">rest-of-line" causes pcretest to + write the compiled pattern to the file whose name is "rest-of-line". + This is a straight binary dump of the data, with the saved pointer to + the character tables forced to be NULL. The study data, if any, is + written too. After writing, pcretest reads a new pattern. + + (ii) If, instead of a pattern, ": new target + : new target + : use native compiler + : use native linker + : handle Windows platform correctly + : ditto + : ditto + copy DLL to top builddir before testing + + As part of these changes, -no-undefined was removed again. This was reported + to give trouble on HP-UX 11.0, so getting rid of it seems like a good idea + in any case. + +3. Some tidies to get rid of compiler warnings: + + . In the match_data structure, match_limit was an unsigned long int, whereas + match_call_count was an int. I've made them both unsigned long ints. + + . In pcretest the fact that a const uschar * doesn't automatically cast to + a void * provoked a warning. + + . Turning on some more compiler warnings threw up some "shadow" variables + and a few more missing casts. + +4. If PCRE was complied with UTF-8 support, but called without the PCRE_UTF8 + option, a class that contained a single character with a value between 128 + and 255 (e.g. /[\xFF]/) caused PCRE to crash. + +5. If PCRE was compiled with UTF-8 support, but called without the PCRE_UTF8 + option, a class that contained several characters, but with at least one + whose value was between 128 and 255 caused PCRE to crash. + + +Version 4.1 12-Mar-03 +--------------------- + +1. Compiling with gcc -pedantic found a couple of places where casts were +needed, and a string in dftables.c that was longer than standard compilers are +required to support. + +2. Compiling with Sun's compiler found a few more places where the code could +be tidied up in order to avoid warnings. + +3. The variables for cross-compiling were called HOST_CC and HOST_CFLAGS; the +first of these names is deprecated in the latest Autoconf in favour of the name +CC_FOR_BUILD, because "host" is typically used to mean the system on which the +compiled code will be run. I can't find a reference for HOST_CFLAGS, but by +analogy I have changed it to CFLAGS_FOR_BUILD. + +4. Added -no-undefined to the linking command in the Makefile, because this is +apparently helpful for Windows. To make it work, also added "-L. -lpcre" to the +linking step for the pcreposix library. + +5. PCRE was failing to diagnose the case of two named groups with the same +name. + +6. A problem with one of PCRE's optimizations was discovered. PCRE remembers a +literal character that is needed in the subject for a match, and scans along to +ensure that it is present before embarking on the full matching process. This +saves time in cases of nested unlimited repeats that are never going to match. +Problem: the scan can take a lot of time if the subject is very long (e.g. +megabytes), thus penalizing straightforward matches. It is now done only if the +amount of subject to be scanned is less than 1000 bytes. + +7. A lesser problem with the same optimization is that it was recording the +first character of an anchored pattern as "needed", thus provoking a search +right along the subject, even when the first match of the pattern was going to +fail. The "needed" character is now not set for anchored patterns, unless it +follows something in the pattern that is of non-fixed length. Thus, it still +fulfils its original purpose of finding quick non-matches in cases of nested +unlimited repeats, but isn't used for simple anchored patterns such as /^abc/. + + +Version 4.0 17-Feb-03 +--------------------- + +1. If a comment in an extended regex that started immediately after a meta-item +extended to the end of string, PCRE compiled incorrect data. This could lead to +all kinds of weird effects. Example: /#/ was bad; /()#/ was bad; /a#/ was not. + +2. Moved to autoconf 2.53 and libtool 1.4.2. + +3. Perl 5.8 no longer needs "use utf8" for doing UTF-8 things. Consequently, +the special perltest8 script is no longer needed - all the tests can be run +from a single perltest script. + +4. From 5.004, Perl has not included the VT character (0x0b) in the set defined +by \s. It has now been removed in PCRE. This means it isn't recognized as +whitespace in /x regexes too, which is the same as Perl. Note that the POSIX +class [:space:] *does* include VT, thereby creating a mess. + +5. Added the class [:blank:] (a GNU extension from Perl 5.8) to match only +space and tab. + +6. Perl 5.005 was a long time ago. It's time to amalgamate the tests that use +its new features into the main test script, reducing the number of scripts. + +7. Perl 5.8 has changed the meaning of patterns like /a(?i)b/. Earlier versions +were backward compatible, and made the (?i) apply to the whole pattern, as if +/i were given. Now it behaves more logically, and applies the option setting +only to what follows. PCRE has been changed to follow suit. However, if it +finds options settings right at the start of the pattern, it extracts them into +the global options, as before. Thus, they show up in the info data. + +8. Added support for the \Q...\E escape sequence. Characters in between are +treated as literals. This is slightly different from Perl in that $ and @ are +also handled as literals inside the quotes. In Perl, they will cause variable +interpolation. Note the following examples: + + Pattern PCRE matches Perl matches + + \Qabc$xyz\E abc$xyz abc followed by the contents of $xyz + \Qabc\$xyz\E abc\$xyz abc\$xyz + \Qabc\E\$\Qxyz\E abc$xyz abc$xyz + +For compatibility with Perl, \Q...\E sequences are recognized inside character +classes as well as outside them. + +9. Re-organized 3 code statements in pcretest to avoid "overflow in +floating-point constant arithmetic" warnings from a Microsoft compiler. Added a +(size_t) cast to one statement in pcretest and one in pcreposix to avoid +signed/unsigned warnings. + +10. SunOS4 doesn't have strtoul(). This was used only for unpicking the -o +option for pcretest, so I've replaced it by a simple function that does just +that job. + +11. pcregrep was ending with code 0 instead of 2 for the commands "pcregrep" or +"pcregrep -". + +12. Added "possessive quantifiers" ?+, *+, ++, and {,}+ which come from Sun's +Java package. This provides some syntactic sugar for simple cases of what my +documentation calls "once-only subpatterns". A pattern such as x*+ is the same +as (?>x*). In other words, if what is inside (?>...) is just a single repeated +item, you can use this simplified notation. Note that only makes sense with +greedy quantifiers. Consequently, the use of the possessive quantifier forces +greediness, whatever the setting of the PCRE_UNGREEDY option. + +13. A change of greediness default within a pattern was not taking effect at +the current level for patterns like /(b+(?U)a+)/. It did apply to parenthesized +subpatterns that followed. Patterns like /b+(?U)a+/ worked because the option +was abstracted outside. + +14. PCRE now supports the \G assertion. It is true when the current matching +position is at the start point of the match. This differs from \A when the +starting offset is non-zero. Used with the /g option of pcretest (or similar +code), it works in the same way as it does for Perl's /g option. If all +alternatives of a regex begin with \G, the expression is anchored to the start +match position, and the "anchored" flag is set in the compiled expression. + +15. Some bugs concerning the handling of certain option changes within patterns +have been fixed. These applied to options other than (?ims). For example, +"a(?x: b c )d" did not match "XabcdY" but did match "Xa b c dY". It should have +been the other way round. Some of this was related to change 7 above. + +16. PCRE now gives errors for /[.x.]/ and /[=x=]/ as unsupported POSIX +features, as Perl does. Previously, PCRE gave the warnings only for /[[.x.]]/ +and /[[=x=]]/. PCRE now also gives an error for /[:name:]/ because it supports +POSIX classes only within a class (e.g. /[[:alpha:]]/). + +17. Added support for Perl's \C escape. This matches one byte, even in UTF8 +mode. Unlike ".", it always matches newline, whatever the setting of +PCRE_DOTALL. However, PCRE does not permit \C to appear in lookbehind +assertions. Perl allows it, but it doesn't (in general) work because it can't +calculate the length of the lookbehind. At least, that's the case for Perl +5.8.0 - I've been told they are going to document that it doesn't work in +future. + +18. Added an error diagnosis for escapes that PCRE does not support: these are +\L, \l, \N, \P, \p, \U, \u, and \X. + +19. Although correctly diagnosing a missing ']' in a character class, PCRE was +reading past the end of the pattern in cases such as /[abcd/. + +20. PCRE was getting more memory than necessary for patterns with classes that +contained both POSIX named classes and other characters, e.g. /[[:space:]abc/. + +21. Added some code, conditional on #ifdef VPCOMPAT, to make life easier for +compiling PCRE for use with Virtual Pascal. + +22. Small fix to the Makefile to make it work properly if the build is done +outside the source tree. + +23. Added a new extension: a condition to go with recursion. If a conditional +subpattern starts with (?(R) the "true" branch is used if recursion has +happened, whereas the "false" branch is used only at the top level. + +24. When there was a very long string of literal characters (over 255 bytes +without UTF support, over 250 bytes with UTF support), the computation of how +much memory was required could be incorrect, leading to segfaults or other +strange effects. + +25. PCRE was incorrectly assuming anchoring (either to start of subject or to +start of line for a non-DOTALL pattern) when a pattern started with (.*) and +there was a subsequent back reference to those brackets. This meant that, for +example, /(.*)\d+\1/ failed to match "abc123bc". Unfortunately, it isn't +possible to check for precisely this case. All we can do is abandon the +optimization if .* occurs inside capturing brackets when there are any back +references whatsoever. (See below for a better fix that came later.) + +26. The handling of the optimization for finding the first character of a +non-anchored pattern, and for finding a character that is required later in the +match were failing in some cases. This didn't break the matching; it just +failed to optimize when it could. The way this is done has been re-implemented. + +27. Fixed typo in error message for invalid (?R item (it said "(?p"). + +28. Added a new feature that provides some of the functionality that Perl +provides with (?{...}). The facility is termed a "callout". The way it is done +in PCRE is for the caller to provide an optional function, by setting +pcre_callout to its entry point. Like pcre_malloc and pcre_free, this is a +global variable. By default it is unset, which disables all calling out. To get +the function called, the regex must include (?C) at appropriate points. This +is, in fact, equivalent to (?C0), and any number <= 255 may be given with (?C). +This provides a means of identifying different callout points. When PCRE +reaches such a point in the regex, if pcre_callout has been set, the external +function is called. It is provided with data in a structure called +pcre_callout_block, which is defined in pcre.h. If the function returns 0, +matching continues; if it returns a non-zero value, the match at the current +point fails. However, backtracking will occur if possible. [This was changed +later and other features added - see item 49 below.] + +29. pcretest is upgraded to test the callout functionality. It provides a +callout function that displays information. By default, it shows the start of +the match and the current position in the text. There are some new data escapes +to vary what happens: + + \C+ in addition, show current contents of captured substrings + \C- do not supply a callout function + \C!n return 1 when callout number n is reached + \C!n!m return 1 when callout number n is reached for the mth time + +30. If pcregrep was called with the -l option and just a single file name, it +output "" if a match was found, instead of the file name. + +31. Improve the efficiency of the POSIX API to PCRE. If the number of capturing +slots is less than POSIX_MALLOC_THRESHOLD, use a block on the stack to pass to +pcre_exec(). This saves a malloc/free per call. The default value of +POSIX_MALLOC_THRESHOLD is 10; it can be changed by --with-posix-malloc-threshold +when configuring. + +32. The default maximum size of a compiled pattern is 64K. There have been a +few cases of people hitting this limit. The code now uses macros to handle the +storing of links as offsets within the compiled pattern. It defaults to 2-byte +links, but this can be changed to 3 or 4 bytes by --with-link-size when +configuring. Tests 2 and 5 work only with 2-byte links because they output +debugging information about compiled patterns. + +33. Internal code re-arrangements: + +(a) Moved the debugging function for printing out a compiled regex into + its own source file (printint.c) and used #include to pull it into + pcretest.c and, when DEBUG is defined, into pcre.c, instead of having two + separate copies. + +(b) Defined the list of op-code names for debugging as a macro in + internal.h so that it is next to the definition of the opcodes. + +(c) Defined a table of op-code lengths for simpler skipping along compiled + code. This is again a macro in internal.h so that it is next to the + definition of the opcodes. + +34. Added support for recursive calls to individual subpatterns, along the +lines of Robin Houston's patch (but implemented somewhat differently). + +35. Further mods to the Makefile to help Win32. Also, added code to pcregrep to +allow it to read and process whole directories in Win32. This code was +contributed by Lionel Fourquaux; it has not been tested by me. + +36. Added support for named subpatterns. The Python syntax (?P...) is +used to name a group. Names consist of alphanumerics and underscores, and must +be unique. Back references use the syntax (?P=name) and recursive calls use +(?P>name) which is a PCRE extension to the Python extension. Groups still have +numbers. The function pcre_fullinfo() can be used after compilation to extract +a name/number map. There are three relevant calls: + + PCRE_INFO_NAMEENTRYSIZE yields the size of each entry in the map + PCRE_INFO_NAMECOUNT yields the number of entries + PCRE_INFO_NAMETABLE yields a pointer to the map. + +The map is a vector of fixed-size entries. The size of each entry depends on +the length of the longest name used. The first two bytes of each entry are the +group number, most significant byte first. There follows the corresponding +name, zero terminated. The names are in alphabetical order. + +37. Make the maximum literal string in the compiled code 250 for the non-UTF-8 +case instead of 255. Making it the same both with and without UTF-8 support +means that the same test output works with both. + +38. There was a case of malloc(0) in the POSIX testing code in pcretest. Avoid +calling malloc() with a zero argument. + +39. Change 25 above had to resort to a heavy-handed test for the .* anchoring +optimization. I've improved things by keeping a bitmap of backreferences with +numbers 1-31 so that if .* occurs inside capturing brackets that are not in +fact referenced, the optimization can be applied. It is unlikely that a +relevant occurrence of .* (i.e. one which might indicate anchoring or forcing +the match to follow \n) will appear inside brackets with a number greater than +31, but if it does, any back reference > 31 suppresses the optimization. + +40. Added a new compile-time option PCRE_NO_AUTO_CAPTURE. This has the effect +of disabling numbered capturing parentheses. Any opening parenthesis that is +not followed by ? behaves as if it were followed by ?: but named parentheses +can still be used for capturing (and they will acquire numbers in the usual +way). + +41. Redesigned the return codes from the match() function into yes/no/error so +that errors can be passed back from deep inside the nested calls. A malloc +failure while inside a recursive subpattern call now causes the +PCRE_ERROR_NOMEMORY return instead of quietly going wrong. + +42. It is now possible to set a limit on the number of times the match() +function is called in a call to pcre_exec(). This facility makes it possible to +limit the amount of recursion and backtracking, though not in a directly +obvious way, because the match() function is used in a number of different +circumstances. The count starts from zero for each position in the subject +string (for non-anchored patterns). The default limit is, for compatibility, a +large number, namely 10 000 000. You can change this in two ways: + +(a) When configuring PCRE before making, you can use --with-match-limit=n + to set a default value for the compiled library. + +(b) For each call to pcre_exec(), you can pass a pcre_extra block in which + a different value is set. See 45 below. + +If the limit is exceeded, pcre_exec() returns PCRE_ERROR_MATCHLIMIT. + +43. Added a new function pcre_config(int, void *) to enable run-time extraction +of things that can be changed at compile time. The first argument specifies +what is wanted and the second points to where the information is to be placed. +The current list of available information is: + + PCRE_CONFIG_UTF8 + +The output is an integer that is set to one if UTF-8 support is available; +otherwise it is set to zero. + + PCRE_CONFIG_NEWLINE + +The output is an integer that it set to the value of the code that is used for +newline. It is either LF (10) or CR (13). + + PCRE_CONFIG_LINK_SIZE + +The output is an integer that contains the number of bytes used for internal +linkage in compiled expressions. The value is 2, 3, or 4. See item 32 above. + + PCRE_CONFIG_POSIX_MALLOC_THRESHOLD + +The output is an integer that contains the threshold above which the POSIX +interface uses malloc() for output vectors. See item 31 above. + + PCRE_CONFIG_MATCH_LIMIT + +The output is an unsigned integer that contains the default limit of the number +of match() calls in a pcre_exec() execution. See 42 above. + +44. pcretest has been upgraded by the addition of the -C option. This causes it +to extract all the available output from the new pcre_config() function, and to +output it. The program then exits immediately. + +45. A need has arisen to pass over additional data with calls to pcre_exec() in +order to support additional features. One way would have been to define +pcre_exec2() (for example) with extra arguments, but this would not have been +extensible, and would also have required all calls to the original function to +be mapped to the new one. Instead, I have chosen to extend the mechanism that +is used for passing in "extra" data from pcre_study(). + +The pcre_extra structure is now exposed and defined in pcre.h. It currently +contains the following fields: + + flags a bitmap indicating which of the following fields are set + study_data opaque data from pcre_study() + match_limit a way of specifying a limit on match() calls for a specific + call to pcre_exec() + callout_data data for callouts (see 49 below) + +The flag bits are also defined in pcre.h, and are + + PCRE_EXTRA_STUDY_DATA + PCRE_EXTRA_MATCH_LIMIT + PCRE_EXTRA_CALLOUT_DATA + +The pcre_study() function now returns one of these new pcre_extra blocks, with +the actual study data pointed to by the study_data field, and the +PCRE_EXTRA_STUDY_DATA flag set. This can be passed directly to pcre_exec() as +before. That is, this change is entirely upwards-compatible and requires no +change to existing code. + +If you want to pass in additional data to pcre_exec(), you can either place it +in a pcre_extra block provided by pcre_study(), or create your own pcre_extra +block. + +46. pcretest has been extended to test the PCRE_EXTRA_MATCH_LIMIT feature. If a +data string contains the escape sequence \M, pcretest calls pcre_exec() several +times with different match limits, until it finds the minimum value needed for +pcre_exec() to complete. The value is then output. This can be instructive; for +most simple matches the number is quite small, but for pathological cases it +gets very large very quickly. + +47. There's a new option for pcre_fullinfo() called PCRE_INFO_STUDYSIZE. It +returns the size of the data block pointed to by the study_data field in a +pcre_extra block, that is, the value that was passed as the argument to +pcre_malloc() when PCRE was getting memory in which to place the information +created by pcre_study(). The fourth argument should point to a size_t variable. +pcretest has been extended so that this information is shown after a successful +pcre_study() call when information about the compiled regex is being displayed. + +48. Cosmetic change to Makefile: there's no need to have / after $(DESTDIR) +because what follows is always an absolute path. (Later: it turns out that this +is more than cosmetic for MinGW, because it doesn't like empty path +components.) + +49. Some changes have been made to the callout feature (see 28 above): + +(i) A callout function now has three choices for what it returns: + + 0 => success, carry on matching + > 0 => failure at this point, but backtrack if possible + < 0 => serious error, return this value from pcre_exec() + + Negative values should normally be chosen from the set of PCRE_ERROR_xxx + values. In particular, returning PCRE_ERROR_NOMATCH forces a standard + "match failed" error. The error number PCRE_ERROR_CALLOUT is reserved for + use by callout functions. It will never be used by PCRE itself. + +(ii) The pcre_extra structure (see 45 above) has a void * field called + callout_data, with corresponding flag bit PCRE_EXTRA_CALLOUT_DATA. The + pcre_callout_block structure has a field of the same name. The contents of + the field passed in the pcre_extra structure are passed to the callout + function in the corresponding field in the callout block. This makes it + easier to use the same callout-containing regex from multiple threads. For + testing, the pcretest program has a new data escape + + \C*n pass the number n (may be negative) as callout_data + + If the callout function in pcretest receives a non-zero value as + callout_data, it returns that value. + +50. Makefile wasn't handling CFLAGS properly when compiling dftables. Also, +there were some redundant $(CFLAGS) in commands that are now specified as +$(LINK), which already includes $(CFLAGS). + +51. Extensions to UTF-8 support are listed below. These all apply when (a) PCRE +has been compiled with UTF-8 support *and* pcre_compile() has been compiled +with the PCRE_UTF8 flag. Patterns that are compiled without that flag assume +one-byte characters throughout. Note that case-insensitive matching applies +only to characters whose values are less than 256. PCRE doesn't support the +notion of cases for higher-valued characters. + +(i) A character class whose characters are all within 0-255 is handled as + a bit map, and the map is inverted for negative classes. Previously, a + character > 255 always failed to match such a class; however it should + match if the class was a negative one (e.g. [^ab]). This has been fixed. + +(ii) A negated character class with a single character < 255 is coded as + "not this character" (OP_NOT). This wasn't working properly when the test + character was multibyte, either singly or repeated. + +(iii) Repeats of multibyte characters are now handled correctly in UTF-8 + mode, for example: \x{100}{2,3}. + +(iv) The character escapes \b, \B, \d, \D, \s, \S, \w, and \W (either + singly or repeated) now correctly test multibyte characters. However, + PCRE doesn't recognize any characters with values greater than 255 as + digits, spaces, or word characters. Such characters always match \D, \S, + and \W, and never match \d, \s, or \w. + +(v) Classes may now contain characters and character ranges with values + greater than 255. For example: [ab\x{100}-\x{400}]. + +(vi) pcregrep now has a --utf-8 option (synonym -u) which makes it call + PCRE in UTF-8 mode. + +52. The info request value PCRE_INFO_FIRSTCHAR has been renamed +PCRE_INFO_FIRSTBYTE because it is a byte value. However, the old name is +retained for backwards compatibility. (Note that LASTLITERAL is also a byte +value.) + +53. The single man page has become too large. I have therefore split it up into +a number of separate man pages. These also give rise to individual HTML pages; +these are now put in a separate directory, and there is an index.html page that +lists them all. Some hyperlinking between the pages has been installed. + +54. Added convenience functions for handling named capturing parentheses. + +55. Unknown escapes inside character classes (e.g. [\M]) and escapes that +aren't interpreted therein (e.g. [\C]) are literals in Perl. This is now also +true in PCRE, except when the PCRE_EXTENDED option is set, in which case they +are faulted. + +56. Introduced HOST_CC and HOST_CFLAGS which can be set in the environment when +calling configure. These values are used when compiling the dftables.c program +which is run to generate the source of the default character tables. They +default to the values of CC and CFLAGS. If you are cross-compiling PCRE, +you will need to set these values. + +57. Updated the building process for Windows DLL, as provided by Fred Cox. + + +Version 3.9 02-Jan-02 +--------------------- + +1. A bit of extraneous text had somehow crept into the pcregrep documentation. + +2. If --disable-static was given, the building process failed when trying to +build pcretest and pcregrep. (For some reason it was using libtool to compile +them, which is not right, as they aren't part of the library.) + + +Version 3.8 18-Dec-01 +--------------------- + +1. The experimental UTF-8 code was completely screwed up. It was packing the +bytes in the wrong order. How dumb can you get? + + +Version 3.7 29-Oct-01 +--------------------- + +1. In updating pcretest to check change 1 of version 3.6, I screwed up. +This caused pcretest, when used on the test data, to segfault. Unfortunately, +this didn't happen under Solaris 8, where I normally test things. + +2. The Makefile had to be changed to make it work on BSD systems, where 'make' +doesn't seem to recognize that ./xxx and xxx are the same file. (This entry +isn't in ChangeLog distributed with 3.7 because I forgot when I hastily made +this fix an hour or so after the initial 3.7 release.) + + +Version 3.6 23-Oct-01 +--------------------- + +1. Crashed with /(sens|respons)e and \1ibility/ and "sense and sensibility" if +offsets passed as NULL with zero offset count. + +2. The config.guess and config.sub files had not been updated when I moved to +the latest autoconf. + + +Version 3.5 15-Aug-01 +--------------------- + +1. Added some missing #if !defined NOPOSIX conditionals in pcretest.c that +had been forgotten. + +2. By using declared but undefined structures, we can avoid using "void" +definitions in pcre.h while keeping the internal definitions of the structures +private. + +3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a +user point of view, this means that both static and shared libraries are built +by default, but this can be individually controlled. More of the work of +handling this static/shared cases is now inside libtool instead of PCRE's make +file. + +4. The pcretest utility is now installed along with pcregrep because it is +useful for users (to test regexs) and by doing this, it automatically gets +relinked by libtool. The documentation has been turned into a man page, so +there are now .1, .txt, and .html versions in /doc. + +5. Upgrades to pcregrep: + (i) Added long-form option names like gnu grep. + (ii) Added --help to list all options with an explanatory phrase. + (iii) Added -r, --recursive to recurse into sub-directories. + (iv) Added -f, --file to read patterns from a file. + +6. pcre_exec() was referring to its "code" argument before testing that +argument for NULL (and giving an error if it was NULL). + +7. Upgraded Makefile.in to allow for compiling in a different directory from +the source directory. + +8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the +options bits, the pointer it was passed was to an int instead of to an unsigned +long int. This mattered only on 64-bit systems. + +9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is +generated) instead of pcre.in, which it its source. Also made the same change +in several of the .c files. + +10. A new release of gcc defines printf() as a macro, which broke pcretest +because it had an ifdef in the middle of a string argument for printf(). Fixed +by using separate calls to printf(). + +11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure +script, to force use of CR or LF instead of \n in the source. On non-Unix +systems, the value can be set in config.h. + +12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an +absolute limit. Changed the text of the error message to make this clear, and +likewise updated the man page. + +13. The limit of 99 on the number of capturing subpatterns has been removed. +The new limit is 65535, which I hope will not be a "real" limit. + + +Version 3.4 22-Aug-00 +--------------------- + +1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *. + +2. Diagnose condition (?(0) as an error instead of crashing on matching. + + +Version 3.3 01-Aug-00 +--------------------- + +1. If an octal character was given, but the value was greater than \377, it +was not getting masked to the least significant bits, as documented. This could +lead to crashes in some systems. + +2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats +the hyphen as a literal. PCRE used to give an error; it now behaves like Perl. + +3. Added the functions pcre_free_substring() and pcre_free_substring_list(). +These just pass their arguments on to (pcre_free)(), but they are provided +because some uses of PCRE bind it to non-C systems that can call its functions, +but cannot call free() or pcre_free() directly. + +4. Add "make test" as a synonym for "make check". Corrected some comments in +the Makefile. + +5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the +Makefile. + +6. Changed the name of pgrep to pcregrep, because Solaris has introduced a +command called pgrep for grepping around the active processes. + +7. Added the beginnings of support for UTF-8 character strings. + +8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and +RANLIB to ./ltconfig so that they are used by libtool. I think these are all +the relevant ones. (AR is not passed because ./ltconfig does its own figuring +out for the ar command.) + + +Version 3.2 12-May-00 +--------------------- + +This is purely a bug fixing release. + +1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead +of ZA. This was just one example of several cases that could provoke this bug, +which was introduced by change 9 of version 2.00. The code for breaking +infinite loops after an iteration that matches an empty string was't working +correctly. + +2. The pcretest program was not imitating Perl correctly for the pattern /a*/g +when matched against abbab (for example). After matching an empty string, it +wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this +caused it to match further down the string than it should. + +3. The code contained an inclusion of sys/types.h. It isn't clear why this +was there because it doesn't seem to be needed, and it causes trouble on some +systems, as it is not a Standard C header. It has been removed. + +4. Made 4 silly changes to the source to avoid stupid compiler warnings that +were reported on the Macintosh. The changes were from + + while ((c = *(++ptr)) != 0 && c != '\n'); +to + while ((c = *(++ptr)) != 0 && c != '\n') ; + +Totally extraordinary, but if that's what it takes... + +5. PCRE is being used in one environment where neither memmove() nor bcopy() is +available. Added HAVE_BCOPY and an autoconf test for it; if neither +HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which +assumes the way PCRE uses memmove() (always moving upwards). + +6. PCRE is being used in one environment where strchr() is not available. There +was only one use in pcre.c, and writing it out to avoid strchr() probably gives +faster code anyway. + + +Version 3.1 09-Feb-00 +--------------------- + +The only change in this release is the fixing of some bugs in Makefile.in for +the "install" target: + +(1) It was failing to install pcreposix.h. + +(2) It was overwriting the pcre.3 man page with the pcreposix.3 man page. + + +Version 3.0 01-Feb-00 +--------------------- + +1. Add support for the /+ modifier to perltest (to output $` like it does in +pcretest). + +2. Add support for the /g modifier to perltest. + +3. Fix pcretest so that it behaves even more like Perl for /g when the pattern +matches null strings. + +4. Fix perltest so that it doesn't do unwanted things when fed an empty +pattern. Perl treats empty patterns specially - it reuses the most recent +pattern, which is not what we want. Replace // by /(?#)/ in order to avoid this +effect. + +5. The POSIX interface was broken in that it was just handing over the POSIX +captured string vector to pcre_exec(), but (since release 2.00) PCRE has +required a bigger vector, with some working space on the end. This means that +the POSIX wrapper now has to get and free some memory, and copy the results. + +6. Added some simple autoconf support, placing the test data and the +documentation in separate directories, re-organizing some of the +information files, and making it build pcre-config (a GNU standard). Also added +libtool support for building PCRE as a shared library, which is now the +default. + +7. Got rid of the leading zero in the definition of PCRE_MINOR because 08 and +09 are not valid octal constants. Single digits will be used for minor values +less than 10. + +8. Defined REG_EXTENDED and REG_NOSUB as zero in the POSIX header, so that +existing programs that set these in the POSIX interface can use PCRE without +modification. + +9. Added a new function, pcre_fullinfo() with an extensible interface. It can +return all that pcre_info() returns, plus additional data. The pcre_info() +function is retained for compatibility, but is considered to be obsolete. + +10. Added experimental recursion feature (?R) to handle one common case that +Perl 5.6 will be able to do with (?p{...}). + +11. Added support for POSIX character classes like [:alpha:], which Perl is +adopting. + + +Version 2.08 31-Aug-99 +---------------------- + +1. When startoffset was not zero and the pattern began with ".*", PCRE was not +trying to match at the startoffset position, but instead was moving forward to +the next newline as if a previous match had failed. + +2. pcretest was not making use of PCRE_NOTEMPTY when repeating for /g and /G, +and could get into a loop if a null string was matched other than at the start +of the subject. + +3. Added definitions of PCRE_MAJOR and PCRE_MINOR to pcre.h so the version can +be distinguished at compile time, and for completeness also added PCRE_DATE. + +5. Added Paul Sokolovsky's minor changes to make it easy to compile a Win32 DLL +in GnuWin32 environments. + + +Version 2.07 29-Jul-99 +---------------------- + +1. The documentation is now supplied in plain text form and HTML as well as in +the form of man page sources. + +2. C++ compilers don't like assigning (void *) values to other pointer types. +In particular this affects malloc(). Although there is no problem in Standard +C, I've put in casts to keep C++ compilers happy. + +3. Typo on pcretest.c; a cast of (unsigned char *) in the POSIX regexec() call +should be (const char *). + +4. If NOPOSIX is defined, pcretest.c compiles without POSIX support. This may +be useful for non-Unix systems who don't want to bother with the POSIX stuff. +However, I haven't made this a standard facility. The documentation doesn't +mention it, and the Makefile doesn't support it. + +5. The Makefile now contains an "install" target, with editable destinations at +the top of the file. The pcretest program is not installed. + +6. pgrep -V now gives the PCRE version number and date. + +7. Fixed bug: a zero repetition after a literal string (e.g. /abcde{0}/) was +causing the entire string to be ignored, instead of just the last character. + +8. If a pattern like /"([^\\"]+|\\.)*"/ is applied in the normal way to a +non-matching string, it can take a very, very long time, even for strings of +quite modest length, because of the nested recursion. PCRE now does better in +some of these cases. It does this by remembering the last required literal +character in the pattern, and pre-searching the subject to ensure it is present +before running the real match. In other words, it applies a heuristic to detect +some types of certain failure quickly, and in the above example, if presented +with a string that has no trailing " it gives "no match" very quickly. + +9. A new runtime option PCRE_NOTEMPTY causes null string matches to be ignored; +other alternatives are tried instead. + + +Version 2.06 09-Jun-99 +---------------------- + +1. Change pcretest's output for amount of store used to show just the code +space, because the remainder (the data block) varies in size between 32-bit and +64-bit systems. + +2. Added an extra argument to pcre_exec() to supply an offset in the subject to +start matching at. This allows lookbehinds to work when searching for multiple +occurrences in a string. + +3. Added additional options to pcretest for testing multiple occurrences: + + /+ outputs the rest of the string that follows a match + /g loops for multiple occurrences, using the new startoffset argument + /G loops for multiple occurrences by passing an incremented pointer + +4. PCRE wasn't doing the "first character" optimization for patterns starting +with \b or \B, though it was doing it for other lookbehind assertions. That is, +it wasn't noticing that a match for a pattern such as /\bxyz/ has to start with +the letter 'x'. On long subject strings, this gives a significant speed-up. + + +Version 2.05 21-Apr-99 +---------------------- + +1. Changed the type of magic_number from int to long int so that it works +properly on 16-bit systems. + +2. Fixed a bug which caused patterns starting with .* not to work correctly +when the subject string contained newline characters. PCRE was assuming +anchoring for such patterns in all cases, which is not correct because .* will +not pass a newline unless PCRE_DOTALL is set. It now assumes anchoring only if +DOTALL is set at top level; otherwise it knows that patterns starting with .* +must be retried after every newline in the subject. + + +Version 2.04 18-Feb-99 +---------------------- + +1. For parenthesized subpatterns with repeats whose minimum was zero, the +computation of the store needed to hold the pattern was incorrect (too large). +If such patterns were nested a few deep, this could multiply and become a real +problem. + +2. Added /M option to pcretest to show the memory requirement of a specific +pattern. Made -m a synonym of -s (which does this globally) for compatibility. + +3. Subpatterns of the form (regex){n,m} (i.e. limited maximum) were being +compiled in such a way that the backtracking after subsequent failure was +pessimal. Something like (a){0,3} was compiled as (a)?(a)?(a)? instead of +((a)((a)(a)?)?)? with disastrous performance if the maximum was of any size. + + +Version 2.03 02-Feb-99 +---------------------- + +1. Fixed typo and small mistake in man page. + +2. Added 4th condition (GPL supersedes if conflict) and created separate +LICENCE file containing the conditions. + +3. Updated pcretest so that patterns such as /abc\/def/ work like they do in +Perl, that is the internal \ allows the delimiter to be included in the +pattern. Locked out the use of \ as a delimiter. If \ immediately follows +the final delimiter, add \ to the end of the pattern (to test the error). + +4. Added the convenience functions for extracting substrings after a successful +match. Updated pcretest to make it able to test these functions. + + +Version 2.02 14-Jan-99 +---------------------- + +1. Initialized the working variables associated with each extraction so that +their saving and restoring doesn't refer to uninitialized store. + +2. Put dummy code into study.c in order to trick the optimizer of the IBM C +compiler for OS/2 into generating correct code. Apparently IBM isn't going to +fix the problem. + +3. Pcretest: the timing code wasn't using LOOPREPEAT for timing execution +calls, and wasn't printing the correct value for compiling calls. Increased the +default value of LOOPREPEAT, and the number of significant figures in the +times. + +4. Changed "/bin/rm" in the Makefile to "-rm" so it works on Windows NT. + +5. Renamed "deftables" as "dftables" to get it down to 8 characters, to avoid +a building problem on Windows NT with a FAT file system. + + +Version 2.01 21-Oct-98 +---------------------- + +1. Changed the API for pcre_compile() to allow for the provision of a pointer +to character tables built by pcre_maketables() in the current locale. If NULL +is passed, the default tables are used. + + +Version 2.00 24-Sep-98 +---------------------- + +1. Since the (>?) facility is in Perl 5.005, don't require PCRE_EXTRA to enable +it any more. + +2. Allow quantification of (?>) groups, and make it work correctly. + +3. The first character computation wasn't working for (?>) groups. + +4. Correct the implementation of \Z (it is permitted to match on the \n at the +end of the subject) and add 5.005's \z, which really does match only at the +very end of the subject. + +5. Remove the \X "cut" facility; Perl doesn't have it, and (?> is neater. + +6. Remove the ability to specify CASELESS, MULTILINE, DOTALL, and +DOLLAR_END_ONLY at runtime, to make it possible to implement the Perl 5.005 +localized options. All options to pcre_study() were also removed. + +7. Add other new features from 5.005: + + $(?<= positive lookbehind + $(?a*))*/ (a PCRE_EXTRA facility). + + +Version 1.00 18-Nov-97 +---------------------- + +1. Added compile-time macros to support systems such as SunOS4 which don't have +memmove() or strerror() but have other things that can be used instead. + +2. Arranged that "make clean" removes the executables. + + +Version 0.99 27-Oct-97 +---------------------- + +1. Fixed bug in code for optimizing classes with only one character. It was +initializing a 32-byte map regardless, which could cause it to run off the end +of the memory it had got. + +2. Added, conditional on PCRE_EXTRA, the proposed (?>REGEX) construction. + + +Version 0.98 22-Oct-97 +---------------------- + +1. Fixed bug in code for handling temporary memory usage when there are more +back references than supplied space in the ovector. This could cause segfaults. + + +Version 0.97 21-Oct-97 +---------------------- + +1. Added the \X "cut" facility, conditional on PCRE_EXTRA. + +2. Optimized negated single characters not to use a bit map. + +3. Brought error texts together as macro definitions; clarified some of them; +fixed one that was wrong - it said "range out of order" when it meant "invalid +escape sequence". + +4. Changed some char * arguments to const char *. + +5. Added PCRE_NOTBOL and PCRE_NOTEOL (from POSIX). + +6. Added the POSIX-style API wrapper in pcreposix.a and testing facilities in +pcretest. + + +Version 0.96 16-Oct-97 +---------------------- + +1. Added a simple "pgrep" utility to the distribution. + +2. Fixed an incompatibility with Perl: "{" is now treated as a normal character +unless it appears in one of the precise forms "{ddd}", "{ddd,}", or "{ddd,ddd}" +where "ddd" means "one or more decimal digits". + +3. Fixed serious bug. If a pattern had a back reference, but the call to +pcre_exec() didn't supply a large enough ovector to record the related +identifying subpattern, the match always failed. PCRE now remembers the number +of the largest back reference, and gets some temporary memory in which to save +the offsets during matching if necessary, in order to ensure that +backreferences always work. + +4. Increased the compatibility with Perl in a number of ways: + + (a) . no longer matches \n by default; an option PCRE_DOTALL is provided + to request this handling. The option can be set at compile or exec time. + + (b) $ matches before a terminating newline by default; an option + PCRE_DOLLAR_ENDONLY is provided to override this (but not in multiline + mode). The option can be set at compile or exec time. + + (c) The handling of \ followed by a digit other than 0 is now supposed to be + the same as Perl's. If the decimal number it represents is less than 10 + or there aren't that many previous left capturing parentheses, an octal + escape is read. Inside a character class, it's always an octal escape, + even if it is a single digit. + + (d) An escaped but undefined alphabetic character is taken as a literal, + unless PCRE_EXTRA is set. Currently this just reserves the remaining + escapes. + + (e) {0} is now permitted. (The previous item is removed from the compiled + pattern). + +5. Changed all the names of code files so that the basic parts are no longer +than 10 characters, and abolished the teeny "globals.c" file. + +6. Changed the handling of character classes; they are now done with a 32-byte +bit map always. + +7. Added the -d and /D options to pcretest to make it possible to look at the +internals of compilation without having to recompile pcre. + + +Version 0.95 23-Sep-97 +---------------------- + +1. Fixed bug in pre-pass concerning escaped "normal" characters such as \x5c or +\x20 at the start of a run of normal characters. These were being treated as +real characters, instead of the source characters being re-checked. + + +Version 0.94 18-Sep-97 +---------------------- + +1. The functions are now thread-safe, with the caveat that the global variables +containing pointers to malloc() and free() or alternative functions are the +same for all threads. + +2. Get pcre_study() to generate a bitmap of initial characters for non- +anchored patterns when this is possible, and use it if passed to pcre_exec(). + + +Version 0.93 15-Sep-97 +---------------------- + +1. /(b)|(:+)/ was computing an incorrect first character. + +2. Add pcre_study() to the API and the passing of pcre_extra to pcre_exec(), +but not actually doing anything yet. + +3. Treat "-" characters in classes that cannot be part of ranges as literals, +as Perl does (e.g. [-az] or [az-]). + +4. Set the anchored flag if a branch starts with .* or .*? because that tests +all possible positions. + +5. Split up into different modules to avoid including unneeded functions in a +compiled binary. However, compile and exec are still in one module. The "study" +function is split off. + +6. The character tables are now in a separate module whose source is generated +by an auxiliary program - but can then be edited by hand if required. There are +now no calls to isalnum(), isspace(), isdigit(), isxdigit(), tolower() or +toupper() in the code. + +7. Turn the malloc/free funtions variables into pcre_malloc and pcre_free and +make them global. Abolish the function for setting them, as the caller can now +set them directly. + + +Version 0.92 11-Sep-97 +---------------------- + +1. A repeat with a fixed maximum and a minimum of 1 for an ordinary character +(e.g. /a{1,3}/) was broken (I mis-optimized it). + +2. Caseless matching was not working in character classes if the characters in +the pattern were in upper case. + +3. Make ranges like [W-c] work in the same way as Perl for caseless matching. + +4. Make PCRE_ANCHORED public and accept as a compile option. + +5. Add an options word to pcre_exec() and accept PCRE_ANCHORED and +PCRE_CASELESS at run time. Add escapes \A and \I to pcretest to cause it to +pass them. + +6. Give an error if bad option bits passed at compile or run time. + +7. Add PCRE_MULTILINE at compile and exec time, and (?m) as well. Add \M to +pcretest to cause it to pass that flag. + +8. Add pcre_info(), to get the number of identifying subpatterns, the stored +options, and the first character, if set. + +9. Recognize C+ or C{n,m} where n >= 1 as providing a fixed starting character. + + +Version 0.91 10-Sep-97 +---------------------- + +1. PCRE was failing to diagnose unlimited repeats of subpatterns that could +match the empty string as in /(a*)*/. It was looping and ultimately crashing. + +2. PCRE was looping on encountering an indefinitely repeated back reference to +a subpattern that had matched an empty string, e.g. /(a|)\1*/. It now does what +Perl does - treats the match as successful. + +**** diff --git a/lib/win32/pcre/CleanTxt b/lib/win32/pcre/CleanTxt new file mode 100644 index 0000000000..1f42519c8d --- /dev/null +++ b/lib/win32/pcre/CleanTxt @@ -0,0 +1,113 @@ +#! /usr/bin/perl -w + +# Script to take the output of nroff -man and remove all the backspacing and +# the page footers and the screen commands etc so that it is more usefully +# readable online.

These were not Unix-like in form, and were quite +restricted in what they could do by comparison with Perl. The interesting part +about the algorithm was that the amount of space required to hold the compiled +form of an expression was known in advance. The code to apply an expression did +not operate by backtracking, as the original Henry Spencer code and current +Perl code does, but instead checked all possibilities simultaneously by keeping +a list of current states and checking all of them as it advanced through the +subject string. In the terminology of Jeffrey Friedl's book, it was a "DFA +algorithm", though it was not a traditional Finite State Machine (FSM). When +the pattern was all used up, all remaining states were possible matches, and +the one matching the longest subset of the subject string was chosen. This did +not necessarily maximize the individual wild portions of the pattern, as is +expected in Unix and Perl-style regular expressions. + +Historical note 2 +----------------- + +By contrast, the code originally written by Henry Spencer (which was +subsequently heavily modified for Perl) compiles the expression twice: once in +a dummy mode in order to find out how much store will be needed, and then for +real. (The Perl version probably doesn't do this any more; I'm talking about +the original library.) The execution function operates by backtracking and +maximizing (or, optionally, minimizing in Perl) the amount of the subject that +matches individual wild portions of the pattern. This is an "NFA algorithm" in +Friedl's terminology. + +OK, here's the real stuff +------------------------- + +For the set of functions that form the "basic" PCRE library (which are +unrelated to those mentioned above), I tried at first to invent an algorithm +that used an amount of store bounded by a multiple of the number of characters +in the pattern, to save on compiling time. However, because of the greater +complexity in Perl regular expressions, I couldn't do this. In any case, a +first pass through the pattern is helpful for other reasons. + +Computing the memory requirement: how it was +-------------------------------------------- + +Up to and including release 6.7, PCRE worked by running a very degenerate first +pass to calculate a maximum store size, and then a second pass to do the real +compile - which might use a bit less than the predicted amount of memory. The +idea was that this would turn out faster than the Henry Spencer code because +the first pass is degenerate and the second pass can just store stuff straight +into the vector, which it knows is big enough. + +Computing the memory requirement: how it is +------------------------------------------- + +By the time I was working on a potential 6.8 release, the degenerate first pass +had become very complicated and hard to maintain. Indeed one of the early +things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then +I had a flash of inspiration as to how I could run the real compile function in +a "fake" mode that enables it to compute how much memory it would need, while +actually only ever using a few hundred bytes of working memory, and without too +many tests of the mode that might slow it down. So I re-factored the compiling +functions to work this way. This got rid of about 600 lines of source. It +should make future maintenance and development easier. As this was such a major +change, I never released 6.8, instead upping the number to 7.0 (other quite +major changes were also present in the 7.0 release). + +A side effect of this work was that the previous limit of 200 on the nesting +depth of parentheses was removed. However, there is a downside: pcre_compile() +runs more slowly than before (30% or more, depending on the pattern) because it +is doing a full analysis of the pattern. My hope was that this would not be a +big issue, and in the event, nobody has commented on it. + +Traditional matching function +----------------------------- + +The "traditional", and original, matching function is called pcre_exec(), and +it implements an NFA algorithm, similar to the original Henry Spencer algorithm +and the way that Perl works. This is not surprising, since it is intended to be +as compatible with Perl as possible. This is the function most users of PCRE +will use most of the time. + +Supplementary matching function +------------------------------- + +From PCRE 6.0, there is also a supplementary matching function called +pcre_dfa_exec(). This implements a DFA matching algorithm that searches +simultaneously for all possible matches that start at one point in the subject +string. (Going back to my roots: see Historical Note 1 above.) This function +intreprets the same compiled pattern data as pcre_exec(); however, not all the +facilities are available, and those that are do not always work in quite the +same way. See the user documentation for details. + +The algorithm that is used for pcre_dfa_exec() is not a traditional FSM, +because it may have a number of states active at one time. More work would be +needed at compile time to produce a traditional FSM where only one state is +ever active at once. I believe some other regex matchers work this way. + + +Format of compiled patterns +--------------------------- + +The compiled form of a pattern is a vector of bytes, containing items of +variable length. The first byte in an item is an opcode, and the length of the +item is either implicit in the opcode or contained in the data bytes that +follow it. + +In many cases below LINK_SIZE data values are specified for offsets within the +compiled pattern. The default value for LINK_SIZE is 2, but PCRE can be +compiled to use 3-byte or 4-byte values for these offsets (impairing the +performance). This is necessary only when patterns whose compiled length is +greater than 64K are going to be processed. In this description, we assume the +"normal" compilation options. Data values that are counts (e.g. for +quantifiers) are always just two bytes long. + +A list of the opcodes follows: + + +Opcodes with no following data +------------------------------ + +These items are all just one byte long + + OP_END end of pattern + OP_ANY match any one character other than newline + OP_ALLANY match any one character, including newline + OP_ANYBYTE match any single byte, even in UTF-8 mode + OP_SOD match start of data: \A + OP_SOM, start of match (subject + offset): \G + OP_SET_SOM, set start of match (\K) + OP_CIRC ^ (start of data, or after \n in multiline) + OP_NOT_WORD_BOUNDARY \W + OP_WORD_BOUNDARY \w + OP_NOT_DIGIT \D + OP_DIGIT \d + OP_NOT_HSPACE \H + OP_HSPACE \h + OP_NOT_WHITESPACE \S + OP_WHITESPACE \s + OP_NOT_VSPACE \V + OP_VSPACE \v + OP_NOT_WORDCHAR \W + OP_WORDCHAR \w + OP_EODN match end of data or \n at end: \Z + OP_EOD match end of data: \z + OP_DOLL $ (end of data, or before \n in multiline) + OP_EXTUNI match an extended Unicode character + OP_ANYNL match any Unicode newline sequence + + OP_ACCEPT ) These are Perl 5.10's "backtracking + OP_COMMIT ) control verbs". If OP_ACCEPT is inside + OP_FAIL ) capturing parentheses, it may be preceded + OP_PRUNE ) by one or more OP_CLOSE, followed by a 2-byte + OP_SKIP ) number, indicating which parentheses must be + OP_THEN ) closed. + + +Repeating single characters +--------------------------- + +The common repeats (*, +, ?) when applied to a single character use the +following opcodes: + + OP_STAR + OP_MINSTAR + OP_POSSTAR + OP_PLUS + OP_MINPLUS + OP_POSPLUS + OP_QUERY + OP_MINQUERY + OP_POSQUERY + +In ASCII mode, these are two-byte items; in UTF-8 mode, the length is variable. +Those with "MIN" in their name are the minimizing versions. Those with "POS" in +their names are possessive versions. Each is followed by the character that is +to be repeated. Other repeats make use of + + OP_UPTO + OP_MINUPTO + OP_POSUPTO + OP_EXACT + +which are followed by a two-byte count (most significant first) and the +repeated character. OP_UPTO matches from 0 to the given number. A repeat with a +non-zero minimum and a fixed maximum is coded as an OP_EXACT followed by an +OP_UPTO (or OP_MINUPTO or OPT_POSUPTO). + + +Repeating character types +------------------------- + +Repeats of things like \d are done exactly as for single characters, except +that instead of a character, the opcode for the type is stored in the data +byte. The opcodes are: + + OP_TYPESTAR + OP_TYPEMINSTAR + OP_TYPEPOSSTAR + OP_TYPEPLUS + OP_TYPEMINPLUS + OP_TYPEPOSPLUS + OP_TYPEQUERY + OP_TYPEMINQUERY + OP_TYPEPOSQUERY + OP_TYPEUPTO + OP_TYPEMINUPTO + OP_TYPEPOSUPTO + OP_TYPEEXACT + + +Match by Unicode property +------------------------- + +OP_PROP and OP_NOTPROP are used for positive and negative matches of a +character by testing its Unicode property (the \p and \P escape sequences). +Each is followed by two bytes that encode the desired property as a type and a +value. + +Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by +three bytes: OP_PROP or OP_NOTPROP and then the desired property type and +value. + + +Matching literal characters +--------------------------- + +The OP_CHAR opcode is followed by a single character that is to be matched +casefully. For caseless matching, OP_CHARNC is used. In UTF-8 mode, the +character may be more than one byte long. (Earlier versions of PCRE used +multi-character strings, but this was changed to allow some new features to be +added.) + + +Character classes +----------------- + +If there is only one character, OP_CHAR or OP_CHARNC is used for a positive +class, and OP_NOT for a negative one (that is, for something like [^a]). +However, in UTF-8 mode, the use of OP_NOT applies only to characters with +values < 128, because OP_NOT is confined to single bytes. + +Another set of repeating opcodes (OP_NOTSTAR etc.) are used for a repeated, +negated, single-character class. The normal ones (OP_STAR etc.) are used for a +repeated positive single-character class. + +When there's more than one character in a class and all the characters are less +than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a negative +one. In either case, the opcode is followed by a 32-byte bit map containing a 1 +bit for every character that is acceptable. The bits are counted from the least +significant end of each byte. + +The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 mode, +subject characters with values greater than 256 can be handled correctly. For +OP_CLASS they don't match, whereas for OP_NCLASS they do. + +For classes containing characters with values > 255, OP_XCLASS is used. It +optionally uses a bit map (if any characters lie within it), followed by a list +of pairs and single characters. There is a flag character than indicates +whether it's a positive or a negative class. + + +Back references +--------------- + +OP_REF is followed by two bytes containing the reference number. + + +Repeating character classes and back references +----------------------------------------------- + +Single-character classes are handled specially (see above). This section +applies to OP_CLASS and OP_REF. In both cases, the repeat information follows +the base item. The matching code looks at the following opcode to see if it is +one of + + OP_CRSTAR + OP_CRMINSTAR + OP_CRPLUS + OP_CRMINPLUS + OP_CRQUERY + OP_CRMINQUERY + OP_CRRANGE + OP_CRMINRANGE + +All but the last two are just single-byte items. The others are followed by +four bytes of data, comprising the minimum and maximum repeat counts. There are +no special possessive opcodes for these repeats; a possessive repeat is +compiled into an atomic group. + + +Brackets and alternation +------------------------ + +A pair of non-capturing (round) brackets is wrapped round each expression at +compile time, so alternation always happens in the context of brackets. + +[Note for North Americans: "bracket" to some English speakers, including +myself, can be round, square, curly, or pointy. Hence this usage.] + +Non-capturing brackets use the opcode OP_BRA. Originally PCRE was limited to 99 +capturing brackets and it used a different opcode for each one. From release +3.5, the limit was removed by putting the bracket number into the data for +higher-numbered brackets. From release 7.0 all capturing brackets are handled +this way, using the single opcode OP_CBRA. + +A bracket opcode is followed by LINK_SIZE bytes which give the offset to the +next alternative OP_ALT or, if there aren't any branches, to the matching +OP_KET opcode. Each OP_ALT is followed by LINK_SIZE bytes giving the offset to +the next one, or to the OP_KET opcode. For capturing brackets, the bracket +number immediately follows the offset, always as a 2-byte item. + +OP_KET is used for subpatterns that do not repeat indefinitely, while +OP_KETRMIN and OP_KETRMAX are used for indefinite repetitions, minimally or +maximally respectively. All three are followed by LINK_SIZE bytes giving (as a +positive number) the offset back to the matching bracket opcode. + +If a subpattern is quantified such that it is permitted to match zero times, it +is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are +single-byte opcodes that tell the matcher that skipping the following +subpattern entirely is a valid branch. In the case of the first two, not +skipping the pattern is also valid (greedy and non-greedy). The third is used +when a pattern has the quantifier {0,0}. It cannot be entirely discarded, +because it may be called as a subroutine from elsewhere in the regex. + +A subpattern with an indefinite maximum repetition is replicated in the +compiled data its minimum number of times (or once with OP_BRAZERO if the +minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX +as appropriate. + +A subpattern with a bounded maximum repetition is replicated in a nested +fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO +before each replication after the minimum, so that, for example, (abc){2,5} is +compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group +has the same number. + +When a repeated subpattern has an unbounded upper limit, it is checked to see +whether it could match an empty string. If this is the case, the opcode in the +final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher +that it needs to check for matching an empty string when it hits OP_KETRMIN or +OP_KETRMAX, and if so, to break the loop. + + +Assertions +---------- + +Forward assertions are just like other subpatterns, but starting with one of +the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes +OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion +is OP_REVERSE, followed by a two byte count of the number of characters to move +back the pointer in the subject string. When operating in UTF-8 mode, the count +is a character count rather than a byte count. A separate count is present in +each alternative of a lookbehind assertion, allowing them to have different +fixed lengths. + + +Once-only (atomic) subpatterns +------------------------------ + +These are also just like other subpatterns, but they start with the opcode +OP_ONCE. The check for matching an empty string in an unbounded repeat is +handled entirely at runtime, so there is just this one opcode. + + +Conditional subpatterns +----------------------- + +These are like other subpatterns, but they start with the opcode OP_COND, or +OP_SCOND for one that might match an empty string in an unbounded repeat. If +the condition is a back reference, this is stored at the start of the +subpattern using the opcode OP_CREF followed by two bytes containing the +reference number. OP_NCREF is used instead if the reference was generated by +name (so that the runtime code knows to check for duplicate names). + +If the condition is "in recursion" (coded as "(?(R)"), or "in recursion of +group x" (coded as "(?(Rx)"), the group number is stored at the start of the +subpattern using the opcode OP_RREF or OP_NRREF (cf OP_NCREF), and a value of +zero for "the whole pattern". For a DEFINE condition, just the single byte +OP_DEF is used (it has no associated data). Otherwise, a conditional subpattern +always starts with one of the assertions. + + +Recursion +--------- + +Recursion either matches the current regex, or some subexpression. The opcode +OP_RECURSE is followed by an value which is the offset to the starting bracket +from the start of the whole pattern. From release 6.5, OP_RECURSE is +automatically wrapped inside OP_ONCE brackets (because otherwise some patterns +broke it). OP_RECURSE is also used for "subroutine" calls, even though they +are not strictly a recursion. + + +Callout +------- + +OP_CALLOUT is followed by one byte of data that holds a callout number in the +range 0 to 254 for manual callouts, or 255 for an automatic callout. In both +cases there follows a two-byte value giving the offset in the pattern to the +start of the following item, and another two-byte item giving the length of the +next item. + + +Changing options +---------------- + +If any of the /i, /m, or /s options are changed within a pattern, an OP_OPT +opcode is compiled, followed by one byte containing the new settings of these +flags. If there are several alternatives, there is an occurrence of OP_OPT at +the start of all those following the first options change, to set appropriate +options for the start of the alternative. Immediately after the end of the +group there is another such item to reset the flags to their previous values. A +change of flag right at the very start of the pattern can be handled entirely +at compile time, and so does not cause anything to be put into the compiled +data. + +Philip Hazel +October 2009 diff --git a/lib/win32/pcre/INSTALL b/lib/win32/pcre/INSTALL new file mode 100644 index 0000000000..8b82ade08e --- /dev/null +++ b/lib/win32/pcre/INSTALL @@ -0,0 +1,291 @@ +Installation Instructions +************************* + +Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005, +2006, 2007, 2008 Free Software Foundation, Inc. + + This file is free documentation; the Free Software Foundation gives +unlimited permission to copy, distribute and modify it. + +Basic Installation +================== + + Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *Note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options.

There are also some +enhancements. Restrictions on patterns used for partial matching have been +removed, extra information is given for partial matches, the partial matching +process has been improved, and an option to make a partial match override a +full match is available. The "study" process has been enhanced by finding a +lower bound matching length. Groups with duplicate numbers may now have +duplicated names without the use of PCRE_DUPNAMES. However, they may not have +different names. The documentation has been revised to reflect these changes. +The version number has been expanded to 3 digits as it is clear that the rate +of change is not slowing down. + + +Release 7.9 11-Apr-09 +--------------------- + +Mostly bugfixes and tidies with just a couple of minor functional additions. + + +Release 7.8 05-Sep-08 +--------------------- + +More bug fixes, plus a performance improvement in Unicode character property +lookup. + + +Release 7.7 07-May-08 +--------------------- + +This is once again mainly a bug-fix release, but there are a couple of new +features. + + +Release 7.6 28-Jan-08 +--------------------- + +The main reason for having this release so soon after 7.5 is because it fixes a +potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In +addition, the CMake configuration files have been brought up to date. + + +Release 7.5 10-Jan-08 +--------------------- + +This is mainly a bug-fix release. However the ability to link pcregrep with +libz or libbz2 and the ability to link pcretest with libreadline have been +added. Also the --line-offsets and --file-offsets options were added to +pcregrep. + + +Release 7.4 21-Sep-07 +--------------------- + +The only change of specification is the addition of options to control whether +\R matches any Unicode line ending (the default) or just CR, LF, and CRLF. +Otherwise, the changes are bug fixes and a refactoring to reduce the number of +relocations needed in a shared library. There have also been some documentation +updates, in particular, some more information about using CMake to build PCRE +has been added to the NON-UNIX-USE file. + + +Release 7.3 28-Aug-07 +--------------------- + +Most changes are bug fixes. Some that are not: + +1. There is some support for Perl 5.10's experimental "backtracking control + verbs" such as (*PRUNE). + +2. UTF-8 checking is now as per RFC 3629 instead of RFC 2279; this is more + restrictive in the strings it accepts. + +3. Checking for potential integer overflow has been made more dynamic, and as a + consequence there is no longer a hard limit on the size of a subpattern that + has a limited repeat count. + +4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec() + no longer advance by two characters instead of one when an unanchored match + fails at CRLF if there are explicit CR or LF matches within the pattern. + This gets rid of some anomalous effects that previously occurred. + +5. Some PCRE-specific settings for varying the newline options at the start of + a pattern have been added. + + +Release 7.2 19-Jun-07 +--------------------- + +WARNING: saved patterns that were compiled by earlier versions of PCRE must be +recompiled for use with 7.2 (necessitated by the addition of \K, \h, \H, \v, +and \V). + +Correction to the notes for 7.1: the note about shared libraries for Windows is +wrong. Previously, three libraries were built, but each could function +independently. For example, the pcreposix library also included all the +functions from the basic pcre library. The change is that the three libraries +are no longer independent. They are like the Unix libraries. To use the +pcreposix functions, for example, you need to link with both the pcreposix and +the basic pcre library. + +Some more features from Perl 5.10 have been added: + + (?-n) and (?+n) relative references for recursion and subroutines. + + (?(-n) and (?(+n) relative references as conditions. + + \k{name} and \g{name} are synonyms for \k. + + \K to reset the start of the matched string; for example, (foo)\Kbar + matches bar preceded by foo, but only sets bar as the matched string. + + (?| introduces a group where the capturing parentheses in each alternative + start from the same number; for example, (?|(abc)|(xyz)) sets capturing + parentheses number 1 in both cases. + + \h, \H, \v, \V match horizontal and vertical whitespace, respectively. + + +Release 7.1 24-Apr-07 +--------------------- + +There is only one new feature in this release: a linebreak setting of +PCRE_NEWLINE_ANYCRLF. It is a cut-down version of PCRE_NEWLINE_ANY, which +recognizes only CRLF, CR, and LF as linebreaks. + +A few bugs are fixed (see ChangeLog for details), but the major change is a +complete re-implementation of the build system. This now has full Autotools +support and so is now "standard" in some sense. It should help with compiling +PCRE in a wide variety of environments. + +NOTE: when building shared libraries for Windows, three dlls are now built, +called libpcre, libpcreposix, and libpcrecpp. Previously, everything was +included in a single dll. + +Another important change is that the dftables auxiliary program is no longer +compiled and run at "make" time by default. Instead, a default set of character +tables (assuming ASCII coding) is used. If you want to use dftables to generate +the character tables as previously, add --enable-rebuild-chartables to the +"configure" command. You must do this if you are compiling PCRE to run on a +system that uses EBCDIC code. + +There is a discussion about character tables in the README file. The default is +not to use dftables so that that there is no problem when cross-compiling. + + +Release 7.0 19-Dec-06 +--------------------- + +This release has a new major number because there have been some internal +upheavals to facilitate the addition of new optimizations and other facilities, +and to make subsequent maintenance and extension easier. Compilation is likely +to be a bit slower, but there should be no major effect on runtime performance. +Previously compiled patterns are NOT upwards compatible with this release. If +you have saved compiled patterns from a previous release, you will have to +re-compile them. Important changes that are visible to users are: + +1. The Unicode property tables have been updated to Unicode 5.0.0, which adds + some more scripts. + +2. The option PCRE_NEWLINE_ANY causes PCRE to recognize any Unicode newline + sequence as a newline. + +3. The \R escape matches a single Unicode newline sequence as a single unit. + +4. New features that will appear in Perl 5.10 are now in PCRE. These include + alternative Perl syntax for named parentheses, and Perl syntax for + recursion. + +5. The C++ wrapper interface has been extended by the addition of a + QuoteMeta function and the ability to allow copy construction and + assignment. + +For a complete list of changes, see the ChangeLog file. + + +Release 6.7 04-Jul-06 +--------------------- + +The main additions to this release are the ability to use the same name for +multiple sets of parentheses, and support for CRLF line endings in both the +library and pcregrep (and in pcretest for testing). + +Thanks to Ian Taylor, the stack usage for many kinds of pattern has been +significantly reduced for certain subject strings. + + +Release 6.5 01-Feb-06 +--------------------- + +Important changes in this release: + +1. A number of new features have been added to pcregrep. + +2. The Unicode property tables have been updated to Unicode 4.1.0, and the + supported properties have been extended with script names such as "Arabic", + and the derived properties "Any" and "L&". This has necessitated a change to + the interal format of compiled patterns. Any saved compiled patterns that + use \p or \P must be recompiled. + +3. The specification of recursion in patterns has been changed so that all + recursive subpatterns are automatically treated as atomic groups. Thus, for + example, (?R) is treated as if it were (?>(?R)). This is necessary because + otherwise there are situations where recursion does not work. + +See the ChangeLog for a complete list of changes, which include a number of bug +fixes and tidies. + + +Release 6.0 07-Jun-05 +--------------------- + +The release number has been increased to 6.0 because of the addition of several +major new pieces of functionality. + +A new function, pcre_dfa_exec(), which implements pattern matching using a DFA +algorithm, has been added. This has a number of advantages for certain cases, +though it does run more slowly, and lacks the ability to capture substrings. On +the other hand, it does find all matches, not just the first, and it works +better for partial matching. The pcrematching man page discusses the +differences. + +The pcretest program has been enhanced so that it can make use of the new +pcre_dfa_exec() matching function and the extra features it provides. + +The distribution now includes a C++ wrapper library. This is built +automatically if a C++ compiler is found. The pcrecpp man page discusses this +interface. + +The code itself has been re-organized into many more files, one for each +function, so it no longer requires everything to be linked in when static +linkage is used. As a consequence, some internal functions have had to have +their names exposed. These functions all have names starting with _pcre_. They +are undocumented, and are not intended for use by outside callers. + +The pcregrep program has been enhanced with new functionality such as +multiline-matching and options for output more matching context. See the +ChangeLog for a complete list of changes to the library and the utility +programs. + + +Release 5.0 13-Sep-04 +--------------------- + +The licence under which PCRE is released has been changed to the more +conventional "BSD" licence. + +In the code, some bugs have been fixed, and there are also some major changes +in this release (which is why I've increased the number to 5.0). Some changes +are internal rearrangements, and some provide a number of new facilities. The +new features are: + +1. There's an "automatic callout" feature that inserts callouts before every + item in the regex, and there's a new callout field that gives the position + in the pattern - useful for debugging and tracing. + +2. The extra_data structure can now be used to pass in a set of character + tables at exec time. This is useful if compiled regex are saved and re-used + at a later time when the tables may not be at the same address. If the + default internal tables are used, the pointer saved with the compiled + pattern is now set to NULL, which means that you don't need to do anything + special unless you are using custom tables. + +3. It is possible, with some restrictions on the content of the regex, to + request "partial" matching. A special return code is given if all of the + subject string matched part of the regex. This could be useful for testing + an input field as it is being typed. + +4. There is now some optional support for Unicode character properties, which + means that the patterns items such as \p{Lu} and \X can now be used. Only + the general category properties are supported. If PCRE is compiled with this + support, an additional 90K data structure is include, which increases the + size of the library dramatically. + +5. There is support for saving compiled patterns and re-using them later. + +6. There is support for running regular expressions that were compiled on a + different host with the opposite endianness. + +7. The pcretest program has been extended to accommodate the new features. + +The main internal rearrangement is that sequences of literal characters are no +longer handled as strings. Instead, each character is handled on its own. This +makes some UTF-8 handling easier, and makes the support of partial matching +possible. Compiled patterns containing long literal strings will be larger as a +result of this change; I hope that performance will not be much affected. + + +Release 4.5 01-Dec-03 +--------------------- + +Again mainly a bug-fix and tidying release, with only a couple of new features: + +1. It's possible now to compile PCRE so that it does not use recursive +function calls when matching. Instead it gets memory from the heap. This slows +things down, but may be necessary on systems with limited stacks. + +2. UTF-8 string checking has been tightened to reject overlong sequences and to +check that a starting offset points to the start of a character. Failure of the +latter returns a new error code: PCRE_ERROR_BADUTF8_OFFSET. + +3. PCRE can now be compiled for systems that use EBCDIC code. + + +Release 4.4 21-Aug-03 +--------------------- + +This is mainly a bug-fix and tidying release. The only new feature is that PCRE +checks UTF-8 strings for validity by default. There is an option to suppress +this, just in case anybody wants that teeny extra bit of performance. + + +Releases 4.1 - 4.3 +------------------ + +Sorry, I forgot about updating the NEWS file for these releases. Please take a +look at ChangeLog. + + +Release 4.0 17-Feb-03 +--------------------- + +There have been a lot of changes for the 4.0 release, adding additional +functionality and mending bugs. Below is a list of the highlights of the new +functionality. For full details of these features, please consult the +documentation. For a complete list of changes, see the ChangeLog file. + +1. Support for Perl's \Q...\E escapes. + +2. "Possessive quantifiers" ?+, *+, ++, and {,}+ which come from Sun's Java +package. They provide some syntactic sugar for simple cases of "atomic +grouping". + +3. Support for the \G assertion. It is true when the current matching position +is at the start point of the match. + +4. A new feature that provides some of the functionality that Perl provides +with (?{...}). The facility is termed a "callout". The way it is done in PCRE +is for the caller to provide an optional function, by setting pcre_callout to +its entry point. To get the function called, the regex must include (?C) at +appropriate points. + +5. Support for recursive calls to individual subpatterns. This makes it really +easy to get totally confused. + +6. Support for named subpatterns. The Python syntax (?P...) is used to +name a group. + +7. Several extensions to UTF-8 support; it is now fairly complete. There is an +option for pcregrep to make it operate in UTF-8 mode. + +8. The single man page has been split into a number of separate man pages. +These also give rise to individual HTML pages which are put in a separate +directory. There is an index.html page that lists them all. Some hyperlinking +between the pages has been installed. + + +Release 3.5 15-Aug-01 +--------------------- + +1. The configuring system has been upgraded to use later versions of autoconf +and libtool. By default it builds both a shared and a static library if the OS +supports it. You can use --disable-shared or --disable-static on the configure +command if you want only one of them. + +2. The pcretest utility is now installed along with pcregrep because it is +useful for users (to test regexs) and by doing this, it automatically gets +relinked by libtool. The documentation has been turned into a man page, so +there are now .1, .txt, and .html versions in /doc. + +3. Upgrades to pcregrep: + (i) Added long-form option names like gnu grep. + (ii) Added --help to list all options with an explanatory phrase. + (iii) Added -r, --recursive to recurse into sub-directories. + (iv) Added -f, --file to read patterns from a file. + +4. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure +script, to force use of CR or LF instead of \n in the source. On non-Unix +systems, the value can be set in config.h. + +5. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an +absolute limit. Changed the text of the error message to make this clear, and +likewise updated the man page. + +6. The limit of 99 on the number of capturing subpatterns has been removed. +The new limit is 65535, which I hope will not be a "real" limit. + + +Release 3.3 01-Aug-00 +--------------------- + +There is some support for UTF-8 character strings. This is incomplete and +experimental. The documentation describes what is and what is not implemented. +Otherwise, this is just a bug-fixing release. + + +Release 3.0 01-Feb-00 +--------------------- + +1. A "configure" script is now used to configure PCRE for Unix systems. It +builds a Makefile, a config.h file, and the pcre-config script. + +2. PCRE is built as a shared library by default. + +3. There is support for POSIX classes such as [:alpha:]. + +5. There is an experimental recursion feature. + +---------------------------------------------------------------------------- + IMPORTANT FOR THOSE UPGRADING FROM VERSIONS BEFORE 2.00 + +Please note that there has been a change in the API such that a larger +ovector is required at matching time, to provide some additional workspace. +The new man page has details. This change was necessary in order to support +some of the new functionality in Perl 5.005. + + IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.00 + +Another (I hope this is the last!) change has been made to the API for the +pcre_compile() function. An additional argument has been added to make it +possible to pass over a pointer to character tables built in the current +locale by pcre_maketables(). To use the default tables, this new arguement +should be passed as NULL. + + IMPORTANT FOR THOSE UPGRADING FROM VERSION 2.05 + +Yet another (and again I hope this really is the last) change has been made +to the API for the pcre_exec() function. An additional argument has been +added to make it possible to start the match other than at the start of the +subject string. This is important if there are lookbehinds. The new man +page has the details, but you just want to convert existing programs, all +you need to do is to stick in a new fifth argument to pcre_exec(), with a +value of zero. For example, change + + pcre_exec(pattern, extra, subject, length, options, ovec, ovecsize) +to + pcre_exec(pattern, extra, subject, length, 0, options, ovec, ovecsize) + +**** diff --git a/lib/win32/pcre/NON-UNIX-USE b/lib/win32/pcre/NON-UNIX-USE new file mode 100644 index 0000000000..aca81bd563 --- /dev/null +++ b/lib/win32/pcre/NON-UNIX-USE @@ -0,0 +1,498 @@ +Compiling PCRE on non-Unix systems +---------------------------------- + +This document contains the following sections: + + General + Generic instructions for the PCRE C library + The C++ wrapper functions + Building for virtual Pascal + Stack size in Windows environments + Linking programs in Windows environments + Comments about Win32 builds + Building PCRE on Windows with CMake + Use of relative paths with CMake on Windows + Testing with RunTest.bat + Building under Windows with BCC5.5 + Building PCRE on OpenVMS + Building PCRE on Stratus OpenVOS + + +GENERAL + +I (Philip Hazel) have no experience of Windows or VMS sytems and how their +libraries work. The items in the PCRE distribution and Makefile that relate to +anything other than Unix-like systems are untested by me. + +There are some other comments and files (including some documentation in CHM +format) in the Contrib directory on the FTP site: + + ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib + +If you want to compile PCRE for a non-Unix system (especially for a system that +does not support "configure" and "make" files), note that the basic PCRE +library consists entirely of code written in Standard C, and so should compile +successfully on any system that has a Standard C compiler and library. The C++ +wrapper functions are a separate issue (see below). + +The PCRE distribution includes a "configure" file for use by the Configure/Make +build system, as found in many Unix-like environments. There is also support +support for CMake, which some users prefer, especially in Windows environments. +There are some instructions for CMake under Windows in the section entitled +"Building PCRE with CMake" below. CMake can also be used to build PCRE in +Unix-like systems. + + +GENERIC INSTRUCTIONS FOR THE PCRE C LIBRARY + +The following are generic comments about building the PCRE C library "by hand". + + (1) Copy or rename the file config.h.generic as config.h, and edit the macro + settings that it contains to whatever is appropriate for your environment. + In particular, if you want to force a specific value for newline, you can + define the NEWLINE macro. When you compile any of the PCRE modules, you + must specify -DHAVE_CONFIG_H to your compiler so that config.h is included + in the sources. + + An alternative approach is not to edit config.h, but to use -D on the + compiler command line to make any changes that you need to the + configuration options. In this case -DHAVE_CONFIG_H must not be set. + + NOTE: There have been occasions when the way in which certain parameters + in config.h are used has changed between releases. (In the configure/make + world, this is handled automatically.) When upgrading to a new release, + you are strongly advised to review config.h.generic before re-using what + you had previously. + + (2) Copy or rename the file pcre.h.generic as pcre.h. + + (3) EITHER: + Copy or rename file pcre_chartables.c.dist as pcre_chartables.c. + + OR: + Compile dftables.c as a stand-alone program (using -DHAVE_CONFIG_H if + you have set up config.h), and then run it with the single argument + "pcre_chartables.c". This generates a set of standard character tables + and writes them to that file. The tables are generated using the default + C locale for your system. If you want to use a locale that is specified + by LC_xxx environment variables, add the -L option to the dftables + command. You must use this method if you are building on a system that + uses EBCDIC code. + + The tables in pcre_chartables.c are defaults. The caller of PCRE can + specify alternative tables at run time. + + (4) Ensure that you have the following header files: + + pcre_internal.h + ucp.h + + (5) Also ensure that you have the following file, which is #included as source + when building a debugging version of PCRE, and is also used by pcretest. + + pcre_printint.src + + (6) Compile the following source files, setting -DHAVE_CONFIG_H as a compiler + option if you have set up config.h with your configuration, or else use + other -D settings to change the configuration as required. + + pcre_chartables.c + pcre_compile.c + pcre_config.c + pcre_dfa_exec.c + pcre_exec.c + pcre_fullinfo.c + pcre_get.c + pcre_globals.c + pcre_info.c + pcre_maketables.c + pcre_newline.c + pcre_ord2utf8.c + pcre_refcount.c + pcre_study.c + pcre_tables.c + pcre_try_flipped.c + pcre_ucd.c + pcre_valid_utf8.c + pcre_version.c + pcre_xclass.c + + Make sure that you include -I. in the compiler command (or equivalent for + an unusual compiler) so that all included PCRE header files are first + sought in the current directory. Otherwise you run the risk of picking up + a previously-installed file from somewhere else. + + (7) Now link all the compiled code into an object library in whichever form + your system keeps such libraries. This is the basic PCRE C library. If + your system has static and shared libraries, you may have to do this once + for each type. + + (8) Similarly, compile pcreposix.c (remembering -DHAVE_CONFIG_H if necessary) + and link the result (on its own) as the pcreposix library. + + (9) Compile the test program pcretest.c (again, don't forget -DHAVE_CONFIG_H). + This needs the functions in the pcre and pcreposix libraries when linking. + It also needs the pcre_printint.src source file, which it #includes. + +(10) Run pcretest on the testinput files in the testdata directory, and check + that the output matches the corresponding testoutput files. Note that the + supplied files are in Unix format, with just LF characters as line + terminators. You may need to edit them to change this if your system uses + a different convention. If you are using Windows, you probably should use + the wintestinput3 file instead of testinput3 (and the corresponding output + file). This is a locale test; wintestinput3 sets the locale to "french" + rather than "fr_FR", and there some minor output differences. + +(11) If you want to use the pcregrep command, compile and link pcregrep.c; it + uses only the basic PCRE library (it does not need the pcreposix library). + + +THE C++ WRAPPER FUNCTIONS + +The PCRE distribution also contains some C++ wrapper functions and tests, +contributed by Google Inc. On a system that can use "configure" and "make", +the functions are automatically built into a library called pcrecpp. It should +be straightforward to compile the .cc files manually on other systems. The +files called xxx_unittest.cc are test programs for each of the corresponding +xxx.cc files. + + +BUILDING FOR VIRTUAL PASCAL + +A script for building PCRE using Borland's C++ compiler for use with VPASCAL +was contributed by Alexander Tokarev. Stefan Weber updated the script and added +additional files. The following files in the distribution are for building PCRE +for use with VP/Borland: makevp_c.txt, makevp_l.txt, makevp.bat, pcregexp.pas. + + +STACK SIZE IN WINDOWS ENVIRONMENTS + +The default processor stack size of 1Mb in some Windows environments is too +small for matching patterns that need much recursion. In particular, test 2 may +fail because of this. Normally, running out of stack causes a crash, but there +have been cases where the test program has just died silently. See your linker +documentation for how to increase stack size if you experience problems. The +Linux default of 8Mb is a reasonable choice for the stack, though even that can +be too small for some pattern/subject combinations. + +PCRE has a compile configuration option to disable the use of stack for +recursion so that heap is used instead. However, pattern matching is +significantly slower when this is done. There is more about stack usage in the +"pcrestack" documentation. + + +LINKING PROGRAMS IN WINDOWS ENVIRONMENTS + +If you want to statically link a program against a PCRE library in the form of +a non-dll .a file, you must define PCRE_STATIC before including pcre.h, +otherwise the pcre_malloc() and pcre_free() exported functions will be declared +__declspec(dllimport), with unwanted results. + + +CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS + +It is possible to compile programs to use different calling conventions using +MSVC. Search the web for "calling conventions" for more information. To make it +easier to change the calling convention for the exported functions in the +PCRE library, the macro PCRE_CALL_CONVENTION is present in all the external +definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is +not set, it defaults to empty; the default calling convention is then used +(which is what is wanted most of the time). + + +COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE WITH CMAKE" below) + +There are two ways of building PCRE using the "configure, make, make install" +paradigm on Windows systems: using MinGW or using Cygwin. These are not at all +the same thing; they are completely different from each other. There is also +support for building using CMake, which some users find a more straightforward +way of building PCRE under Windows. However, the tests are not run +automatically when CMake is used. + +The MinGW home page (http://www.mingw.org/) says this: + + MinGW: A collection of freely available and freely distributable Windows + specific header files and import libraries combined with GNU toolsets that + allow one to produce native Windows programs that do not rely on any + 3rd-party C runtime DLLs. + +The Cygwin home page (http://www.cygwin.com/) says this: + + Cygwin is a Linux-like environment for Windows. It consists of two parts: + + . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing + substantial Linux API functionality + + . A collection of tools which provide Linux look and feel. + + The Cygwin DLL currently works with all recent, commercially released x86 32 + bit and 64 bit versions of Windows, with the exception of Windows CE. + +On both MinGW and Cygwin, PCRE should build correctly using: + + ./configure && make && make install + +This should create two libraries called libpcre and libpcreposix, and, if you +have enabled building the C++ wrapper, a third one called libpcrecpp. These are +independent libraries: when you like with libpcreposix or libpcrecpp you must +also link with libpcre, which contains the basic functions. (Some earlier +releases of PCRE included the basic libpcre functions in libpcreposix. This no +longer happens.) + +A user submitted a special-purpose patch that makes it easy to create +"pcre.dll" under mingw32 using the "msys" environment. It provides "pcre.dll" +as a special target. If you use this target, no other files are built, and in +particular, the pcretest and pcregrep programs are not built. An example of how +this might be used is: + + ./configure --enable-utf --disable-cpp CFLAGS="-03 -s"; make pcre.dll + +Using Cygwin's compiler generates libraries and executables that depend on +cygwin1.dll. If a library that is generated this way is distributed, +cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL +licence, this forces not only PCRE to be under the GPL, but also the entire +application. A distributor who wants to keep their own code proprietary must +purchase an appropriate Cygwin licence. + +MinGW has no such restrictions. The MinGW compiler generates a library or +executable that can run standalone on Windows without any third party dll or +licensing issues. + +But there is more complication: + +If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is +to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a +front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's +gcc and MinGW's gcc). So, a user can: + +. Build native binaries by using MinGW or by getting Cygwin and using + -mno-cygwin. + +. Build binaries that depend on cygwin1.dll by using Cygwin with the normal + compiler flags. + +The test files that are supplied with PCRE are in Unix format, with LF +characters as line terminators. It may be necessary to change the line +terminators in order to get some of the tests to work. We hope to improve +things in this area in future. + + +BUILDING PCRE ON WINDOWS WITH CMAKE + +CMake is an alternative configuration facility that can be used instead of the +traditional Unix "configure". CMake creates project files (make files, solution +files, etc.) tailored to numerous development environments, including Visual +Studio, Borland, Msys, MinGW, NMake, and Unix. The following instructions +were contributed by a PCRE user. + +1. Install the latest CMake version available from http://www.cmake.org/, and + ensure that cmake\bin is on your path. + +2. Unzip (retaining folder structure) the PCRE source tree into a source + directory such as C:\pcre. + +3. Create a new, empty build directory, for example C:\pcre\build\ + +4. Run cmake-gui from the Shell envirornment of your build tool, for example, + Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. + +5. Enter C:\pcre\pcre-xx and C:\pcre\build for the source and build + directories, respectively. + +6. Hit the "Configure" button. + +7. Select the particular IDE / build tool that you are using (Visual + Studio, MSYS makefiles, MinGW makefiles, etc.) + +8. The GUI will then list several configuration options. This is where + you can enable UTF-8 support or other PCRE optional features. + +9. Hit "Configure" again. The adjacent "Generate" button should now be + active. + +10. Hit "Generate". + +11. The build directory should now contain a usable build system, be it a + solution file for Visual Studio, makefiles for MinGW, etc. Exit from + cmake-gui and use the generated build system with your compiler or IDE. + + +USE OF RELATIVE PATHS WITH CMAKE ON WINDOWS + +A PCRE user comments as follows: + +I thought that others may want to know the current state of +CMAKE_USE_RELATIVE_PATHS support on Windows. + +Here it is: +-- AdditionalIncludeDirectories is only partially modified (only the +first path - see below) +-- Only some of the contained file paths are modified - shown below for +pcre.vcproj +-- It properly modifies + +I am sure CMake people can fix that if they want to. Until then one will +need to replace existing absolute paths in project files with relative +paths manually (e.g. from VS) - relative to project file location. I did +just that before being told to try CMAKE_USE_RELATIVE_PATHS. Not a big +deal. + +AdditionalIncludeDirectories="E:\builds\pcre\build;E:\builds\pcre\pcre-7.5;" +AdditionalIncludeDirectories=".;E:\builds\pcre\pcre-7.5;" + +RelativePath="pcre.h"> +RelativePath="pcre_chartables.c"> +RelativePath="pcre_chartables.c.rule"> + + +TESTING WITH RUNTEST.BAT + +1. Copy RunTest.bat into the directory where pcretest.exe has been created. + +2. Edit RunTest.bat and insert a line that indentifies the relative location of + the pcre source, e.g.: + + set srcdir=..\pcre-7.4-RC3 + +3. Run RunTest.bat from a command shell environment. Test outputs will + automatically be compared to expected results, and discrepancies will + identified in the console output. + +4. To test pcrecpp, run pcrecpp_unittest.exe, pcre_stringpiece_unittest.exe and + pcre_scanner_unittest.exe. + + +BUILDING UNDER WINDOWS WITH BCC5.5 + +Michael Roy sent these comments about building PCRE under Windows with BCC5.5: + + Some of the core BCC libraries have a version of PCRE from 1998 built in, + which can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a + version mismatch. I'm including an easy workaround below, if you'd like to + include it in the non-unix instructions: + + When linking a project with BCC5.5, pcre.lib must be included before any of + the libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command + line. + + +BUILDING UNDER WINDOWS CE WITH VISUAL STUDIO 200x + +Vincent Richomme sent a zip archive of files to help with this process. They +can be found in the file "pcre-vsbuild.zip" in the Contrib directory of the FTP +site. + + +BUILDING PCRE ON OPENVMS + +Dan Mooney sent the following comments about building PCRE on OpenVMS. They +relate to an older version of PCRE that used fewer source files, so the exact +commands will need changing. See the current list of source files above. + +"It was quite easy to compile and link the library. I don't have a formal +make file but the attached file [reproduced below] contains the OpenVMS DCL +commands I used to build the library.

The distribution also includes a +set of C++ wrapper functions (see the pcrecpp man page for details), courtesy +of Google Inc. + +In addition, there is a set of C wrapper functions that are based on the POSIX +regular expression API (see the pcreposix man page). These end up in the +library called libpcreposix. Note that this just provides a POSIX calling +interface to PCRE; the regular expressions themselves still follow Perl syntax +and semantics. The POSIX API is restricted, and does not give full access to +all of PCRE's facilities. + +The header file for the POSIX-style functions is called pcreposix.h. The +official POSIX name is regex.h, but I did not want to risk possible problems +with existing files of that name by distributing it that way. To use PCRE with +an existing program that uses the POSIX API, pcreposix.h will have to be +renamed or pointed at by a link. + +If you are using the POSIX interface to PCRE and there is already a POSIX regex +library installed on your system, as well as worrying about the regex.h header +file (as mentioned above), you must also take care when linking programs to +ensure that they link with PCRE's libpcreposix library. Otherwise they may pick +up the POSIX functions of the same name from the other library. + +One way of avoiding this confusion is to compile PCRE with the addition of +-Dregcomp=PCREregcomp (and similarly for the other POSIX functions) to the +compiler flags (CFLAGS if you are using "configure" -- see below). This has the +effect of renaming the functions so that the names no longer clash. Of course, +you have to do the same thing for your applications, or write them using the +new names. + + +Documentation for PCRE +---------------------- + +If you install PCRE in the normal way on a Unix-like system, you will end up +with a set of man pages whose names all start with "pcre". The one that is just +called "pcre" lists all the others. In addition to these man pages, the PCRE +documentation is supplied in two other forms: + + 1. There are files called doc/pcre.txt, doc/pcregrep.txt, and + doc/pcretest.txt in the source distribution. The first of these is a + concatenation of the text forms of all the section 3 man pages except + those that summarize individual functions. The other two are the text + forms of the section 1 man pages for the pcregrep and pcretest commands. + These text forms are provided for ease of scanning with text editors or + similar tools. They are installed in /share/doc/pcre, where + is the installation prefix (defaulting to /usr/local). + + 2. A set of files containing all the documentation in HTML form, hyperlinked + in various ways, and rooted in a file called index.html, is distributed in + doc/html and installed in /share/doc/pcre/html. + +Users of PCRE have contributed files containing the documentation for various +releases in CHM format. These can be found in the Contrib directory of the FTP +site (see next section). + + +Contributions by users of PCRE +------------------------------ + +You can find contributions from PCRE users in the directory + + ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib + +There is a README file giving brief descriptions of what they are. Some are +complete in themselves; others are pointers to URLs containing relevant files. +Some of this material is likely to be well out-of-date. Several of the earlier +contributions provided support for compiling PCRE on various flavours of +Windows (I myself do not use Windows). Nowadays there is more Windows support +in the standard distribution, so these contibutions have been archived. + + +Building PCRE on non-Unix systems +--------------------------------- + +For a non-Unix system, please read the comments in the file NON-UNIX-USE, +though if your system supports the use of "configure" and "make" you may be +able to build PCRE in the same way as for Unix-like systems. PCRE can also be +configured in many platform environments using the GUI facility provided by +CMake's cmake-gui command. This creates Makefiles, solution files, etc. + +PCRE has been compiled on many different operating systems. It should be +straightforward to build PCRE on any system that has a Standard C compiler and +library, because it uses only Standard C functions. + + +Building PCRE on Unix-like systems +---------------------------------- + +If you are using HP's ANSI C++ compiler (aCC), please see the special note +in the section entitled "Using HP's ANSI C++ compiler (aCC)" below. + +The following instructions assume the use of the widely used "configure, make, +make install" process. There is also support for CMake in the PCRE +distribution; there are some comments about using CMake in the NON-UNIX-USE +file, though it can also be used in Unix-like systems. + +To build PCRE on a Unix-like system, first run the "configure" command from the +PCRE distribution directory, with your current directory set to the directory +where you want the files to be created. This command is a standard GNU +"autoconf" configuration script, for which generic instructions are supplied in +the file INSTALL. + +Most commonly, people build PCRE within its own distribution directory, and in +this case, on many systems, just running "./configure" is sufficient. However, +the usual methods of changing standard defaults are available. For example: + +CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local + +specifies that the C compiler should be run with the flags '-O2 -Wall' instead +of the default, and that "make install" should install PCRE under /opt/local +instead of the default /usr/local. + +If you want to build in a different directory, just run "configure" with that +directory as current. For example, suppose you have unpacked the PCRE source +into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx: + +cd /build/pcre/pcre-xxx +/source/pcre/pcre-xxx/configure + +PCRE is written in C and is normally compiled as a C library. However, it is +possible to build it as a C++ library, though the provided building apparatus +does not have any features to support this. + +There are some optional features that can be included or omitted from the PCRE +library. You can read more about them in the pcrebuild man page. + +. If you want to suppress the building of the C++ wrapper library, you can add + --disable-cpp to the "configure" command. Otherwise, when "configure" is run, + it will try to find a C++ compiler and C++ header files, and if it succeeds, + it will try to build the C++ wrapper. + +. If you want to make use of the support for UTF-8 Unicode character strings in + PCRE, you must add --enable-utf8 to the "configure" command. Without it, the + code for handling UTF-8 is not included in the library. Even when included, + it still has to be enabled by an option at run time. When PCRE is compiled + with this option, its input can only either be ASCII or UTF-8, even when + running on EBCDIC platforms. It is not possible to use both --enable-utf8 and + --enable-ebcdic at the same time. + +. If, in addition to support for UTF-8 character strings, you want to include + support for the \P, \p, and \X sequences that recognize Unicode character + properties, you must add --enable-unicode-properties to the "configure" + command. This adds about 30K to the size of the library (in the form of a + property table); only the basic two-letter properties such as Lu are + supported. + +. You can build PCRE to recognize either CR or LF or the sequence CRLF or any + of the preceding, or any of the Unicode newline sequences as indicating the + end of a line. Whatever you specify at build time is the default; the caller + of PCRE can change the selection at run time. The default newline indicator + is a single LF character (the Unix standard). You can specify the default + newline indicator by adding --enable-newline-is-cr or --enable-newline-is-lf + or --enable-newline-is-crlf or --enable-newline-is-anycrlf or + --enable-newline-is-any to the "configure" command, respectively. + + If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of + the standard tests will fail, because the lines in the test files end with + LF. Even if the files are edited to change the line endings, there are likely + to be some failures. With --enable-newline-is-anycrlf or + --enable-newline-is-any, many tests should succeed, but there may be some + failures. + +. By default, the sequence \R in a pattern matches any Unicode line ending + sequence. This is independent of the option specifying what PCRE considers to + be the end of a line (see above). However, the caller of PCRE can restrict \R + to match only CR, LF, or CRLF. You can make this the default by adding + --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R"). + +. When called via the POSIX interface, PCRE uses malloc() to get additional + storage for processing capturing parentheses if there are more than 10 of + them in a pattern. You can increase this threshold by setting, for example, + + --with-posix-malloc-threshold=20 + + on the "configure" command. + +. PCRE has a counter that can be set to limit the amount of resources it uses. + If the limit is exceeded during a match, the match fails. The default is ten + million. You can change the default by setting, for example, + + --with-match-limit=500000 + + on the "configure" command. This is just the default; individual calls to + pcre_exec() can supply their own value. There is more discussion on the + pcreapi man page. + +. There is a separate counter that limits the depth of recursive function calls + during a matching process. This also has a default of ten million, which is + essentially "unlimited". You can change the default by setting, for example, + + --with-match-limit-recursion=500000 + + Recursive function calls use up the runtime stack; running out of stack can + cause programs to crash in strange ways. There is a discussion about stack + sizes in the pcrestack man page. + +. The default maximum compiled pattern size is around 64K. You can increase + this by adding --with-link-size=3 to the "configure" command. You can + increase it even more by setting --with-link-size=4, but this is unlikely + ever to be necessary. Increasing the internal link size will reduce + performance. + +. You can build PCRE so that its internal match() function that is called from + pcre_exec() does not call itself recursively. Instead, it uses memory blocks + obtained from the heap via the special functions pcre_stack_malloc() and + pcre_stack_free() to save data that would otherwise be saved on the stack. To + build PCRE like this, use + + --disable-stack-for-recursion + + on the "configure" command. PCRE runs more slowly in this mode, but it may be + necessary in environments with limited stack sizes. This applies only to the + pcre_exec() function; it does not apply to pcre_dfa_exec(), which does not + use deeply nested recursion. There is a discussion about stack sizes in the + pcrestack man page. + +. For speed, PCRE uses four tables for manipulating and identifying characters + whose code point values are less than 256. By default, it uses a set of + tables for ASCII encoding that is part of the distribution. If you specify + + --enable-rebuild-chartables + + a program called dftables is compiled and run in the default C locale when + you obey "make". It builds a source file called pcre_chartables.c. If you do + not specify this option, pcre_chartables.c is created as a copy of + pcre_chartables.c.dist. See "Character tables" below for further information. + +. It is possible to compile PCRE for use on systems that use EBCDIC as their + character code (as opposed to ASCII) by specifying + + --enable-ebcdic + + This automatically implies --enable-rebuild-chartables (see above). However, + when PCRE is built this way, it always operates in EBCDIC. It cannot support + both EBCDIC and UTF-8. + +. It is possible to compile pcregrep to use libz and/or libbz2, in order to + read .gz and .bz2 files (respectively), by specifying one or both of + + --enable-pcregrep-libz + --enable-pcregrep-libbz2 + + Of course, the relevant libraries must be installed on your system. + +. It is possible to compile pcretest so that it links with the libreadline + library, by specifying + + --enable-pcretest-libreadline + + If this is done, when pcretest's input is from a terminal, it reads it using + the readline() function. This provides line-editing and history facilities. + Note that libreadline is GPL-licenced, so if you distribute a binary of + pcretest linked in this way, there may be licensing issues. + + Setting this option causes the -lreadline option to be added to the pcretest + build. In many operating environments with a sytem-installed readline + library this is sufficient. However, in some environments (e.g. if an + unmodified distribution version of readline is in use), it may be necessary + to specify something like LIBS="-lncurses" as well. This is because, to quote + the readline INSTALL, "Readline uses the termcap functions, but does not link + with the termcap or curses library itself, allowing applications which link + with readline the to choose an appropriate library." If you get error + messages about missing functions tgetstr, tgetent, tputs, tgetflag, or tgoto, + this is the problem, and linking with the ncurses library should fix it. + +The "configure" script builds the following files for the basic C library: + +. Makefile is the makefile that builds the library +. config.h contains build-time configuration options for the library +. pcre.h is the public PCRE header file +. pcre-config is a script that shows the settings of "configure" options +. libpcre.pc is data for the pkg-config command +. libtool is a script that builds shared and/or static libraries +. RunTest is a script for running tests on the basic C library +. RunGrepTest is a script for running tests on the pcregrep command + +Versions of config.h and pcre.h are distributed in the PCRE tarballs under +the names config.h.generic and pcre.h.generic. These are provided for the +benefit of those who have to built PCRE without the benefit of "configure". If +you use "configure", the .generic versions are not used. + +If a C++ compiler is found, the following files are also built: + +. libpcrecpp.pc is data for the pkg-config command +. pcrecpparg.h is a header file for programs that call PCRE via the C++ wrapper +. pcre_stringpiece.h is the header for the C++ "stringpiece" functions + +The "configure" script also creates config.status, which is an executable +script that can be run to recreate the configuration, and config.log, which +contains compiler output from tests that "configure" runs. + +Once "configure" has run, you can run "make". It builds two libraries, called +libpcre and libpcreposix, a test program called pcretest, and the pcregrep +command. If a C++ compiler was found on your system, "make" also builds the C++ +wrapper library, which is called libpcrecpp, and some test programs called +pcrecpp_unittest, pcre_scanner_unittest, and pcre_stringpiece_unittest. +Building the C++ wrapper can be disabled by adding --disable-cpp to the +"configure" command. + +The command "make check" runs all the appropriate tests. Details of the PCRE +tests are given below in a separate section of this document. + +You can use "make install" to install PCRE into live directories on your +system. The following are installed (file names are all relative to the + that is set when "configure" is run): + + Commands (bin): + pcretest + pcregrep + pcre-config + + Libraries (lib): + libpcre + libpcreposix + libpcrecpp (if C++ support is enabled) + + Configuration information (lib/pkgconfig): + libpcre.pc + libpcrecpp.pc (if C++ support is enabled) + + Header files (include): + pcre.h + pcreposix.h + pcre_scanner.h ) + pcre_stringpiece.h ) if C++ support is enabled + pcrecpp.h ) + pcrecpparg.h ) + + Man pages (share/man/man{1,3}): + pcregrep.1 + pcretest.1 + pcre.3 + pcre*.3 (lots more pages, all starting "pcre") + + HTML documentation (share/doc/pcre/html): + index.html + *.html (lots more pages, hyperlinked from index.html) + + Text file documentation (share/doc/pcre): + AUTHORS + COPYING + ChangeLog + LICENCE + NEWS + README + pcre.txt (a concatenation of the man(3) pages) + pcretest.txt the pcretest man page + pcregrep.txt the pcregrep man page + +If you want to remove PCRE from your system, you can run "make uninstall". +This removes all the files that "make install" installed. However, it does not +remove any directories, because these are often shared with other programs. + + +Retrieving configuration information on Unix-like systems +--------------------------------------------------------- + +Running "make install" installs the command pcre-config, which can be used to +recall information about the PCRE configuration and installation. For example: + + pcre-config --version + +prints the version number, and + + pcre-config --libs + +outputs information about where the library is installed. This command can be +included in makefiles for programs that use PCRE, saving the programmer from +having to remember too many details. + +The pkg-config command is another system for saving and retrieving information +about installed libraries. Instead of separate commands for each library, a +single command is used. For example: + + pkg-config --cflags pcre + +The data is held in *.pc files that are installed in a directory called +/lib/pkgconfig. + + +Shared libraries on Unix-like systems +------------------------------------- + +The default distribution builds PCRE as shared libraries and static libraries, +as long as the operating system supports shared libraries. Shared library +support relies on the "libtool" script which is built as part of the +"configure" process. + +The libtool script is used to compile and link both shared and static +libraries. They are placed in a subdirectory called .libs when they are newly +built. The programs pcretest and pcregrep are built to use these uninstalled +libraries (by means of wrapper scripts in the case of shared libraries). When +you use "make install" to install shared libraries, pcregrep and pcretest are +automatically re-built to use the newly installed shared libraries before being +installed themselves. However, the versions left in the build directory still +use the uninstalled libraries. + +To build PCRE using static libraries only you must use --disable-shared when +configuring it. For example: + +./configure --prefix=/usr/gnu --disable-shared + +Then run "make" in the usual way. Similarly, you can use --disable-static to +build only shared libraries. + + +Cross-compiling on Unix-like systems +------------------------------------ + +You can specify CC and CFLAGS in the normal way to the "configure" command, in +order to cross-compile PCRE for some other host. However, you should NOT +specify --enable-rebuild-chartables, because if you do, the dftables.c source +file is compiled and run on the local host, in order to generate the inbuilt +character tables (the pcre_chartables.c file). This will probably not work, +because dftables.c needs to be compiled with the local compiler, not the cross +compiler. + +When --enable-rebuild-chartables is not specified, pcre_chartables.c is created +by making a copy of pcre_chartables.c.dist, which is a default set of tables +that assumes ASCII code. Cross-compiling with the default tables should not be +a problem. + +If you need to modify the character tables when cross-compiling, you should +move pcre_chartables.c.dist out of the way, then compile dftables.c by hand and +run it on the local host to make a new version of pcre_chartables.c.dist. +Then when you cross-compile PCRE this new version of the tables will be used. + + +Using HP's ANSI C++ compiler (aCC) +---------------------------------- + +Unless C++ support is disabled by specifying the "--disable-cpp" option of the +"configure" script, you must include the "-AA" option in the CXXFLAGS +environment variable in order for the C++ components to compile correctly. + +Also, note that the aCC compiler on PA-RISC platforms may have a defect whereby +needed libraries fail to get included when specifying the "-AA" compiler +option. If you experience unresolved symbols when linking the C++ programs, +use the workaround of specifying the following environment variable prior to +running the "configure" script: + + CXXLDFLAGS="-lstd_v2 -lCsup_v2" + + +Using Sun's compilers for Solaris +--------------------------------- + +A user reports that the following configurations work on Solaris 9 sparcv9 and +Solaris 9 x86 (32-bit): + + Solaris 9 sparcv9: ./configure --disable-cpp CC=/bin/cc CFLAGS="-m64 -g" + Solaris 9 x86: ./configure --disable-cpp CC=/bin/cc CFLAGS="-g" + + +Using PCRE from MySQL +--------------------- + +On systems where both PCRE and MySQL are installed, it is possible to make use +of PCRE from within MySQL, as an alternative to the built-in pattern matching. +There is a web page that tells you how to do this: + + http://www.mysqludf.org/lib_mysqludf_preg/index.php + + +Making new tarballs +------------------- + +The command "make dist" creates three PCRE tarballs, in tar.gz, tar.bz2, and +zip formats. The command "make distcheck" does the same, but then does a trial +build of the new distribution to ensure that it works. + +If you have modified any of the man page sources in the doc directory, you +should first run the PrepareRelease script before making a distribution. This +script creates the .txt and HTML forms of the documentation from the man pages. + + +Testing PCRE +------------ + +To test the basic PCRE library on a Unix system, run the RunTest script that is +created by the configuring process. There is also a script called RunGrepTest +that tests the options of the pcregrep command. If the C++ wrapper library is +built, three test programs called pcrecpp_unittest, pcre_scanner_unittest, and +pcre_stringpiece_unittest are also built. + +Both the scripts and all the program tests are run if you obey "make check" or +"make test". For other systems, see the instructions in NON-UNIX-USE. + +The RunTest script runs the pcretest test program (which is documented in its +own man page) on each of the testinput files in the testdata directory in +turn, and compares the output with the contents of the corresponding testoutput +files. A file called testtry is used to hold the main output from pcretest +(testsavedregex is also used as a working file). To run pcretest on just one of +the test files, give its number as an argument to RunTest, for example: + + RunTest 2 + +The first test file can also be fed directly into the perltest.pl script to +check that Perl gives the same results. The only difference you should see is +in the first few lines, where the Perl version is given instead of the PCRE +version. + +The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(), +pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error +detection, and run-time flags that are specific to PCRE, as well as the POSIX +wrapper API. It also uses the debugging flags to check some of the internals of +pcre_compile(). + +If you build PCRE with a locale setting that is not the standard C locale, the +character tables may be different (see next paragraph). In some cases, this may +cause failures in the second set of tests. For example, in a locale where the +isprint() function yields TRUE for characters in the range 128-255, the use of +[:isascii:] inside a character class defines a different set of characters, and +this shows up in this test as a difference in the compiled code, which is being +listed for checking. Where the comparison test output contains [\x00-\x7f] the +test will contain [\x00-\xff], and similarly in some other cases. This is not a +bug in PCRE. + +The third set of tests checks pcre_maketables(), the facility for building a +set of character tables for a specific locale and using them instead of the +default tables. The tests make use of the "fr_FR" (French) locale. Before +running the test, the script checks for the presence of this locale by running +the "locale" command. If that command fails, or if it doesn't include "fr_FR" +in the list of available locales, the third test cannot be run, and a comment +is output to say why. If running this test produces instances of the error + + ** Failed to set locale "fr_FR" + +in the comparison output, it means that locale is not available on your system, +despite being listed by "locale". This does not mean that PCRE is broken. + +[If you are trying to run this test on Windows, you may be able to get it to +work by changing "fr_FR" to "french" everywhere it occurs. Alternatively, use +RunTest.bat. The version of RunTest.bat included with PCRE 7.4 and above uses +Windows versions of test 2. More info on using RunTest.bat is included in the +document entitled NON-UNIX-USE.] + +The fourth test checks the UTF-8 support. It is not run automatically unless +PCRE is built with UTF-8 support. To do this you must set --enable-utf8 when +running "configure". This file can be also fed directly to the perltest.pl +script, provided you are running Perl 5.8 or higher. + +The fifth test checks error handling with UTF-8 encoding, and internal UTF-8 +features of PCRE that are not relevant to Perl. + +The sixth test (which is Perl-5.10 compatible) checks the support for Unicode +character properties. It it not run automatically unless PCRE is built with +Unicode property support. To to this you must set --enable-unicode-properties +when running "configure". + +The seventh, eighth, and ninth tests check the pcre_dfa_exec() alternative +matching function, in non-UTF-8 mode, UTF-8 mode, and UTF-8 mode with Unicode +property support, respectively. The eighth and ninth tests are not run +automatically unless PCRE is build with the relevant support. + +The tenth test checks some internal offsets and code size features; it is run +only when the default "link size" of 2 is set (in other cases the sizes +change). + +The eleventh test checks out features that are new in Perl 5.10, and the +twelfth test checks a number internals and non-Perl features concerned with +Unicode property support. It it not run automatically unless PCRE is built with +Unicode property support. To to this you must set --enable-unicode-properties +when running "configure". + + +Character tables +---------------- + +For speed, PCRE uses four tables for manipulating and identifying characters +whose code point values are less than 256. The final argument of the +pcre_compile() function is a pointer to a block of memory containing the +concatenated tables. A call to pcre_maketables() can be used to generate a set +of tables in the current locale. If the final argument for pcre_compile() is +passed as NULL, a set of default tables that is built into the binary is used. + +The source file called pcre_chartables.c contains the default set of tables. By +default, this is created as a copy of pcre_chartables.c.dist, which contains +tables for ASCII coding. However, if --enable-rebuild-chartables is specified +for ./configure, a different version of pcre_chartables.c is built by the +program dftables (compiled from dftables.c), which uses the ANSI C character +handling functions such as isalnum(), isalpha(), isupper(), islower(), etc. to +build the table sources. This means that the default C locale which is set for +your system will control the contents of these default tables. You can change +the default tables by editing pcre_chartables.c and then re-building PCRE. If +you do this, you should take care to ensure that the file does not get +automatically re-generated. The best way to do this is to move +pcre_chartables.c.dist out of the way and replace it with your customized +tables. + +When the dftables program is run as a result of --enable-rebuild-chartables, +it uses the default C locale that is set on your system. It does not pay +attention to the LC_xxx environment variables. In other words, it uses the +system's default locale rather than whatever the compiling user happens to have +set. If you really do want to build a source set of character tables in a +locale that is specified by the LC_xxx variables, you can run the dftables +program by hand with the -L option. For example: + + ./dftables -L pcre_chartables.c.special + +The first two 256-byte tables provide lower casing and case flipping functions, +respectively. The next table consists of three 32-byte bit maps which identify +digits, "word" characters, and white space, respectively. These are used when +building 32-byte bit maps that represent character classes for code points less +than 256. + +The final 256-byte table has bits indicating various character types, as +follows: + + 1 white space character + 2 letter + 4 decimal digit + 8 hexadecimal digit + 16 alphanumeric or '_' + 128 regular expression metacharacter or binary zero + +You should not alter the set of characters that contain the 128 bit, as that +will cause PCRE to malfunction. + + +File manifest +------------- + +The distribution should contain the following files: + +(A) Source files of the PCRE library functions and their headers: + + dftables.c auxiliary program for building pcre_chartables.c + when --enable-rebuild-chartables is specified + + pcre_chartables.c.dist a default set of character tables that assume ASCII + coding;

+
INTRODUCTION
+

+The PCRE library is a set of functions that implement regular expression +pattern matching using the same syntax and semantics as Perl, with just a few +differences. Some features that appeared in Python and PCRE before they +appeared in Perl are also available using the Python syntax, there is some +support for one or two .NET and Oniguruma syntax items, and there is an option +for requesting some minor changes that give better JavaScript compatibility. +

+

+The current implementation of PCRE corresponds approximately with Perl 5.10, +including support for UTF-8 encoded strings and Unicode general category +properties. However, UTF-8 and Unicode support has to be explicitly enabled; it +is not the default. The Unicode tables correspond to Unicode release 5.1. +

+

+In addition to the Perl-compatible matching function, PCRE contains an +alternative function that matches the same compiled patterns in a different +way. In certain circumstances, the alternative function has some advantages. +For a discussion of the two matching algorithms, see the +pcrematching +page. +

+

+PCRE is written in C and released as a C library. A number of people have +written wrappers and interfaces of various kinds. In particular, Google Inc. +have provided a comprehensive C++ wrapper. This is now included as part of the +PCRE distribution. The +pcrecpp +page has details of this interface. Other people's contributions can be found +in the Contrib directory at the primary FTP site, which is: +ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre +

+

+Details of exactly which Perl regular expression features are and are not +supported by PCRE are given in separate documents. See the +pcrepattern +and +pcrecompat +pages. There is a syntax summary in the +pcresyntax +page. +

+

+Some features of PCRE can be included, excluded, or changed when the library is +built. The +pcre_config() +function makes it possible for a client to discover which features are +available. The features themselves are described in the +pcrebuild +page. Documentation about building PCRE for various operating systems can be +found in the README and NON-UNIX-USE files in the source +distribution. +

+

+The library contains a number of undocumented internal functions and data +tables that are used by more than one of the exported external functions, but +which are not intended for use by external callers. Their names all begin with +"_pcre_", which hopefully will not provoke any name clashes. In some +environments, it is possible to control which external symbols are exported +when a shared library is built, and in these cases the undocumented symbols are +not exported. +

+
USER DOCUMENTATION
+

+The user documentation for PCRE comprises a number of different sections. In +the "man" format, each of these is a separate "man page". In the HTML format, +each is a separate page, linked from the index page. In the plain text format, +all the sections, except the pcredemo section, are concatenated, for ease +of searching. The sections are as follows: +

+  pcre              this document
+  pcre-config       show PCRE installation configuration information
+  pcreapi           details of PCRE's native C API
+  pcrebuild         options for building PCRE
+  pcrecallout       details of the callout feature
+  pcrecompat        discussion of Perl compatibility
+  pcrecpp           details of the C++ wrapper
+  pcredemo          a demonstration C program that uses PCRE
+  pcregrep          description of the pcregrep command
+  pcrematching      discussion of the two matching algorithms
+  pcrepartial       details of the partial matching facility
+  pcrepattern       syntax and semantics of supported regular expressions
+  pcreperform       discussion of performance issues
+  pcreposix         the POSIX-compatible C API

+
+In addition, in the "man" and HTML formats, there is a short page for each +C library function, listing its arguments and results. +

+
LIMITATIONS
+

+There are some size limitations in PCRE but it is hoped that they will never in +practice be relevant. +

+

+The maximum length of a compiled pattern is 65539 (sic) bytes if PCRE is +compiled with the default internal linkage size of 2. If you want to process +regular expressions that are truly enormous, you can compile PCRE with an +internal linkage size of 3 or 4 (see the README file in the source +distribution and the +pcrebuild +documentation for details). In these cases the limit is substantially larger. +However, the speed of execution is slower. +

+

+All values in repeating quantifiers must be less than 65536. +

+

+There is no limit to the number of parenthesized subpatterns, but there can be +no more than 65535 capturing subpatterns. +

+

+The maximum length of name for a named subpattern is 32 characters, and the +maximum number of named subpatterns is 10000. +

+

+The maximum length of a subject string is the largest positive number that an +integer variable can hold. However, when using the traditional matching +function, PCRE uses recursion to handle subpatterns and indefinite repetition. +This means that the available stack space may limit the size of a subject +string that can be processed by certain patterns. For a discussion of stack +issues, see the +pcrestack +documentation. +

+
UTF-8 AND UNICODE PROPERTY SUPPORT
+

+From release 3.3, PCRE has had some support for character strings encoded in +the UTF-8 format. For release 4.0 this was greatly extended to cover most +common requirements, and in release 5.0 additional support for Unicode general +category properties was added. +

+

+In order process UTF-8 strings, you must build PCRE to include UTF-8 support in +the code, and, in addition, you must call +pcre_compile() +with the PCRE_UTF8 option flag, or the pattern must start with the sequence +(*UTF8). When either of these is the case, both the pattern and any subject +strings that are matched against it are treated as UTF-8 strings instead of +strings of 1-byte characters. +

+

+If you compile PCRE with UTF-8 support, but do not use it at run time, the +library will be a bit bigger, but the additional run time overhead is limited +to testing the PCRE_UTF8 flag occasionally, so should not be very big. +

+

+If PCRE is built with Unicode character property support (which implies UTF-8 +support), the escape sequences \p{..}, \P{..}, and \X are supported. +The available properties that can be tested are limited to the general +category properties such as Lu for an upper case letter or Nd for a decimal +number, the Unicode script names such as Arabic or Han, and the derived +properties Any and L&. A full list is given in the +pcrepattern +documentation. Only the short names for properties are supported. For example, +\p{L} matches a letter. Its Perl synonym, \p{Letter}, is not supported. +Furthermore, in Perl, many properties may optionally be prefixed by "Is", for +compatibility with Perl 5.6. PCRE does not support this. +

+
+Validity of UTF-8 strings +
+

+When you set the PCRE_UTF8 flag, the strings passed as patterns and subjects +are (by default) checked for validity on entry to the relevant functions. From +release 7.3 of PCRE, the check is according the rules of RFC 3629, which are +themselves derived from the Unicode specification. Earlier releases of PCRE +followed the rules of RFC 2279, which allows the full range of 31-bit values (0 +to 0x7FFFFFFF). The current check allows only values in the range U+0 to +U+10FFFF, excluding U+D800 to U+DFFF. +

+

+The excluded code points are the "Low Surrogate Area" of Unicode, of which the +Unicode Standard says this: "The Low Surrogate Area does not contain any +character assignments, consequently no character code charts or namelists are +provided for this area. Surrogates are reserved for use with UTF-16 and then +must be used in pairs." The code points that are encoded by UTF-16 pairs are +available as independent code points in the UTF-8 encoding. (In other words, +the whole surrogate thing is a fudge for UTF-16 which unfortunately messes up +UTF-8.) +

+

+If an invalid UTF-8 string is passed to PCRE, an error return +(PCRE_ERROR_BADUTF8) is given. In some situations, you may already know that +your strings are valid, and therefore want to skip these checks in order to +improve performance. If you set the PCRE_NO_UTF8_CHECK flag at compile time or +at run time, PCRE assumes that the pattern or subject it is given +(respectively) contains only valid UTF-8 codes. In this case, it does not +diagnose an invalid UTF-8 string. +

+

+If you pass an invalid UTF-8 string when PCRE_NO_UTF8_CHECK is set, what +happens depends on why the string is invalid. If the string conforms to the +"old" definition of UTF-8 (RFC 2279), it is processed as a string of characters +in the range 0 to 0x7FFFFFFF. In other words, apart from the initial validity +test, PCRE (when in UTF-8 mode) handles strings according to the more liberal +rules of RFC 2279. However, if the string does not even conform to RFC 2279, +the result is undefined. Your program may crash. +

+

+If you want to process strings of values in the full range 0 to 0x7FFFFFFF, +encoded in a UTF-8-like manner as per the old RFC, you can set +PCRE_NO_UTF8_CHECK to bypass the more restrictive test. However, in this +situation, you will have to apply your own validity check. +

+
+General comments about UTF-8 mode +
+

+1. An unbraced hexadecimal escape sequence (such as \xb3) matches a two-byte +UTF-8 character if the value is greater than 127. +

+

+2. Octal numbers up to \777 are recognized, and match two-byte UTF-8 +characters for values greater than \177. +

+

+3. Repeat quantifiers apply to complete UTF-8 characters, not to individual +bytes, for example: \x{100}{3}. +

+

+4. The dot metacharacter matches one UTF-8 character instead of a single byte. +

+

+5. The escape sequence \C can be used to match a single byte in UTF-8 mode, +but its use can lead to some strange effects. This facility is not available in +the alternative matching function, pcre_dfa_exec(). +

+

+6. The character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly +test characters of any code value, but the characters that PCRE recognizes as +digits, spaces, or word characters remain the same set as before, all with +values less than 256. This remains true even when PCRE includes Unicode +property support, because to do otherwise would slow down PCRE in many common +cases. If you really want to test for a wider sense of, say, "digit", you +must use Unicode property tests such as \p{Nd}. Note that this also applies to +\b, because it is defined in terms of \w and \W. +

+

+7. Similarly, characters that match the POSIX named character classes are all +low-valued characters. +

+

+8. However, the Perl 5.10 horizontal and vertical whitespace matching escapes +(\h, \H, \v, and \V) do match all the appropriate Unicode characters. +

+

+9. Case-insensitive matching applies only to characters whose values are less +than 128, unless PCRE is built with Unicode property support. Even when Unicode +property support is available, PCRE still uses its own character tables when +checking the case of low-valued characters, so as not to degrade performance. +The Unicode property information is used only for characters with higher +values. Even when Unicode property support is available, PCRE supports +case-insensitive matching only when there is a one-to-one mapping between a +letter's cases. There are a small number of many-to-one mappings in Unicode; +these are not supported by PCRE. +

+
+DESCRIPTION +
+

+This function matches a compiled regular expression against a given subject +string, using an alternative matching algorithm that scans the subject string +just once (not Perl-compatible).

PCRE API OVERVIEW
+

+PCRE has its own native API, which is described in this document. There are +also some wrapper functions that correspond to the POSIX regular expression +API. These are described in the +pcreposix +documentation. Both of these APIs define a set of C function calls. A C++ +wrapper is distributed with PCRE. It is documented in the +pcrecpp +page. +

+

+The native API C function prototypes are defined in the header file +pcre.h, and on Unix systems the library itself is called libpcre. +It can normally be accessed by adding -lpcre to the command for linking +an application that uses PCRE. The header file defines the macros PCRE_MAJOR +and PCRE_MINOR to contain the major and minor release numbers for the library. +Applications can use these to include support for different releases of PCRE. +

+

+The functions pcre_compile(), pcre_compile2(), pcre_study(), +and pcre_exec() are used for compiling and matching regular expressions +in a Perl-compatible manner. A sample program that demonstrates the simplest +way of using them is provided in the file called pcredemo.c in the PCRE +source distribution. A listing of this program is given in the +pcredemo +documentation, and the +pcresample +documentation describes how to compile and run it. +

+

+A second matching function, pcre_dfa_exec(), which is not +Perl-compatible, is also provided. This uses a different algorithm for the +matching. The alternative algorithm finds all possible matches (at a given +point in the subject), and scans the subject just once (unless there are +lookbehind assertions). However, this algorithm does not return captured +substrings. A description of the two matching algorithms and their advantages +and disadvantages is given in the +pcrematching +documentation. +

+

+In addition to the main compiling and matching functions, there are convenience +functions for extracting captured substrings from a subject string that is +matched by pcre_exec(). They are: +

+  pcre_copy_substring()
+  pcre_copy_named_substring()
+  pcre_get_substring()
+  pcre_get_named_substring()
+  pcre_get_substring_list()
+  pcre_get_stringnumber()
+  pcre_get_stringtable_entries()
+
+pcre_free_substring() and pcre_free_substring_list() are also +provided, to free the memory used for extracted strings. +

+

+The function pcre_maketables() is used to build a set of character tables +in the current locale for passing to pcre_compile(), pcre_exec(), +or pcre_dfa_exec(). This is an optional facility that is provided for +specialist use. Most commonly, no special tables are passed, in which case +internal tables that are generated when PCRE is built are used. +

+

+The function pcre_fullinfo() is used to find out information about a +compiled pattern; pcre_info() is an obsolete version that returns only +some of the available information, but is retained for backwards compatibility. +The function pcre_version() returns a pointer to a string containing the +version of PCRE and its date of release. +

+

+The function pcre_refcount() maintains a reference count in a data block +containing a compiled pattern. This is provided for the benefit of +object-oriented applications. +

+

+The global variables pcre_malloc and pcre_free initially contain +the entry points of the standard malloc() and free() functions, +respectively. PCRE calls the memory management functions via these variables, +so a calling program can replace them if it wishes to intercept the calls. This +should be done before calling any PCRE functions. +

+

+The global variables pcre_stack_malloc and pcre_stack_free are also +indirections to memory management functions. These special functions are used +only when PCRE is compiled to use the heap for remembering data, instead of +recursive function calls, when running the pcre_exec() function. See the +pcrebuild +documentation for details of how to do this. It is a non-standard way of +building PCRE, for use in environments that have limited stacks. Because of the +greater use of memory management, it runs more slowly. Separate functions are +provided so that special-purpose external code can be used for this case. When +used, these functions are always called in a stack-like manner (last obtained, +first freed), and always for memory blocks of the same size. There is a +discussion about PCRE's stack usage in the +pcrestack +documentation. +

+

+The global variable pcre_callout initially contains NULL. It can be set +by the caller to a "callout" function, which PCRE will then call at specified +points during a matching operation. Details are given in the +pcrecallout +documentation. +

+
NEWLINES
+

+PCRE supports five different conventions for indicating line breaks in +strings: a single CR (carriage return) character, a single LF (linefeed) +character, the two-character sequence CRLF, any of the three preceding, or any +Unicode newline sequence. The Unicode newline sequences are the three just +mentioned, plus the single characters VT (vertical tab, U+000B), FF (formfeed, +U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS +(paragraph separator, U+2029). +

+

+Each of the first three conventions is used by at least one operating system as +its standard newline sequence. When PCRE is built, a default can be specified. +The default default is LF, which is the Unix standard. When PCRE is run, the +default can be overridden, either when a pattern is compiled, or when it is +matched. +

+

+At compile time, the newline convention can be specified by the options +argument of pcre_compile(), or it can be specified by special text at the +start of the pattern itself; this overrides any other settings. See the +pcrepattern +page for details of the special character sequences. +

+

+In the PCRE documentation the word "newline" is used to mean "the character or +pair of characters that indicate a line break". The choice of newline +convention affects the handling of the dot, circumflex, and dollar +metacharacters, the handling of #-comments in /x mode, and, when CRLF is a +recognized line ending sequence, the match position advancement for a +non-anchored pattern. There is more detail about this in the +section on pcre_exec() options +below. +

+

+The choice of newline convention does not affect the interpretation of +the \n or \r escape sequences, nor does it affect what \R matches, which is +controlled in a similar way, but by separate options. +

+
MULTITHREADING
+

+The PCRE functions can be used in multi-threading applications, with the +proviso that the memory management functions pointed to by pcre_malloc, +pcre_free, pcre_stack_malloc, and pcre_stack_free, and the +callout function pointed to by pcre_callout, are shared by all threads. +

+

+The compiled form of a regular expression is not altered during matching, so +the same compiled pattern can safely be used by several threads at once. +

+
SAVING PRECOMPILED PATTERNS FOR LATER USE
+

+The compiled form of a regular expression can be saved and re-used at a later +time, possibly by a different program, and even on a host other than the one on +which it was compiled. Details are given in the +pcreprecompile +documentation. However, compiling a regular expression with one version of PCRE +for use with a different version is not guaranteed to work and may cause +crashes. +

+
CHECKING BUILD-TIME OPTIONS
+

+int pcre_config(int what, void *where); +

+

+The function pcre_config() makes it possible for a PCRE client to +discover which optional features have been compiled into the PCRE library. The +pcrebuild +documentation has more details about these optional features. +

+

+The first argument for pcre_config() is an integer, specifying which +information is required; the second argument is a pointer to a variable into +which the information is placed. The following information is available: +

+  PCRE_CONFIG_UTF8
+
+The output is an integer that is set to one if UTF-8 support is available; +otherwise it is set to zero. +
+  PCRE_CONFIG_UNICODE_PROPERTIES
+
+The output is an integer that is set to one if support for Unicode character +properties is available; otherwise it is set to zero. +
+  PCRE_CONFIG_NEWLINE
+
+The output is an integer whose value specifies the default character sequence +that is recognized as meaning "newline". The four values that are supported +are: 10 for LF, 13 for CR, 3338 for CRLF, -2 for ANYCRLF, and -1 for ANY. +Though they are derived from ASCII, the same values are returned in EBCDIC +environments. The default should normally correspond to the standard sequence +for your operating system. +
+  PCRE_CONFIG_BSR
+
+The output is an integer whose value indicates what character sequences the \R +escape sequence matches by default. A value of 0 means that \R matches any +Unicode line ending sequence; a value of 1 means that \R matches only CR, LF, +or CRLF. The default can be overridden when a pattern is compiled or matched. +
+  PCRE_CONFIG_LINK_SIZE
+
+The output is an integer that contains the number of bytes used for internal +linkage in compiled regular expressions. The value is 2, 3, or 4. Larger values +allow larger regular expressions to be compiled, at the expense of slower +matching. The default value of 2 is sufficient for all but the most massive +patterns, since it allows the compiled pattern to be up to 64K in size. +
+  PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
+
+The output is an integer that contains the threshold above which the POSIX +interface uses malloc() for output vectors. Further details are given in +the +pcreposix +documentation. +
+  PCRE_CONFIG_MATCH_LIMIT
+
+The output is a long integer that gives the default limit for the number of +internal matching function calls in a pcre_exec() execution. Further +details are given with pcre_exec() below. +
+  PCRE_CONFIG_MATCH_LIMIT_RECURSION
+
+The output is a long integer that gives the default limit for the depth of +recursion when calling the internal matching function in a pcre_exec() +execution. Further details are given with pcre_exec() below. +
+  PCRE_CONFIG_STACKRECURSE
+
+The output is an integer that is set to one if internal recursion when running +pcre_exec() is implemented by recursive function calls that use the stack +to remember their state. This is the usual way that PCRE is compiled. The +output is zero if PCRE was compiled to use blocks of data on the heap instead +of recursive function calls. In this case, pcre_stack_malloc and +pcre_stack_free are called to manage memory blocks on the heap, thus +avoiding the use of the stack. +

+
COMPILING A PATTERN
+

+pcre *pcre_compile(const char *pattern, int options, +const char **errptr, int *erroffset, +const unsigned char *tableptr); +pcre *pcre_compile2(const char *pattern, int options, +int *errorcodeptr, +const char **errptr, int *erroffset, +const unsigned char *tableptr); +

+

+Either of the functions pcre_compile() or pcre_compile2() can be +called to compile a pattern into an internal form. The only difference between +the two interfaces is that pcre_compile2() has an additional argument, +errorcodeptr, via which a numerical error code can be returned. To avoid +too much repetition, we refer just to pcre_compile() below, but the +information applies equally to pcre_compile2(). +

+

+The pattern is a C string terminated by a binary zero, and is passed in the +pattern argument. A pointer to a single block of memory that is obtained +via pcre_malloc is returned. This contains the compiled code and related +data. The pcre type is defined for the returned block; this is a typedef +for a structure whose contents are not externally defined. It is up to the +caller to free the memory (via pcre_free) when it is no longer required. +

+

+Although the compiled code of a PCRE regex is relocatable, that is, it does not +depend on memory location, the complete pcre data block is not +fully relocatable, because it may contain a copy of the tableptr +argument, which is an address (see below). +

+

+The options argument contains various bit settings that affect the +compilation. It should be zero if no options are required. The available +options are described below. Some of them (in particular, those that are +compatible with Perl, but some others as well) can also be set and unset from +within the pattern (see the detailed description in the +pcrepattern +documentation). For those options that can be different in different parts of +the pattern, the contents of the options argument specifies their +settings at the start of compilation and execution. The PCRE_ANCHORED, +PCRE_BSR_xxx, and PCRE_NEWLINE_xxx options can be set at the time +of matching as well as at compile time. +

+

+If errptr is NULL, pcre_compile() returns NULL immediately. +Otherwise, if compilation of a pattern fails, pcre_compile() returns +NULL, and sets the variable pointed to by errptr to point to a textual +error message. This is a static string that is part of the library. You must +not try to free it. The byte offset from the start of the pattern to the +character that was being processed when the error was discovered is placed in +the variable pointed to by erroffset, which must not be NULL. If it is, +an immediate error is given. Some errors are not detected until checks are +carried out when the whole pattern has been scanned; in this case the offset is +set to the end of the pattern. +

+

+If pcre_compile2() is used instead of pcre_compile(), and the +errorcodeptr argument is not NULL, a non-zero error code number is +returned via this argument in the event of an error. This is in addition to the +textual error message. Error codes and messages are listed below. +

+

+If the final argument, tableptr, is NULL, PCRE uses a default set of +character tables that are built when PCRE is compiled, using the default C +locale. Otherwise, tableptr must be an address that is the result of a +call to pcre_maketables(). This value is stored with the compiled +pattern, and used again by pcre_exec(), unless another table pointer is +passed to it. For more discussion, see the section on locale support below. +

+

+This code fragment shows a typical straightforward call to pcre_compile(): +

+  pcre *re;
+  const char *error;
+  int erroffset;
+  re = pcre_compile(
+    "^A.*Z",          /* the pattern */
+    0,                /* default options */
+    &error,           /* for error message */
+    &erroffset,       /* for error offset */
+    NULL);            /* use default character tables */
+
+The following names for option bits are defined in the pcre.h header +file: +
+  PCRE_ANCHORED
+
+If this bit is set, the pattern is forced to be "anchored", that is, it is +constrained to match only at the first matching point in the string that is +being searched (the "subject string"). This effect can also be achieved by +appropriate constructs in the pattern itself, which is the only way to do it in +Perl. +
+  PCRE_AUTO_CALLOUT
+
+If this bit is set, pcre_compile() automatically inserts callout items, +all with number 255, before each pattern item. For discussion of the callout +facility, see the +pcrecallout +documentation. +
+  PCRE_BSR_ANYCRLF
+  PCRE_BSR_UNICODE
+
+These options (which are mutually exclusive) control what the \R escape +sequence matches. The choice is either to match only CR, LF, or CRLF, or to +match any Unicode newline sequence. The default is specified when PCRE is +built. It can be overridden from within the pattern, or by setting an option +when a compiled pattern is matched. +
+  PCRE_CASELESS
+
+If this bit is set, letters in the pattern match both upper and lower case +letters. It is equivalent to Perl's /i option, and it can be changed within a +pattern by a (?i) option setting. In UTF-8 mode, PCRE always understands the +concept of case for characters whose values are less than 128, so caseless +matching is always possible. For characters with higher values, the concept of +case is supported if PCRE is compiled with Unicode property support, but not +otherwise. If you want to use caseless matching for characters 128 and above, +you must ensure that PCRE is compiled with Unicode property support as well as +with UTF-8 support. +
+  PCRE_DOLLAR_ENDONLY
+
+If this bit is set, a dollar metacharacter in the pattern matches only at the +end of the subject string. Without this option, a dollar also matches +immediately before a newline at the end of the string (but not before any other +newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set. +There is no equivalent to this option in Perl, and no way to set it within a +pattern. +
+  PCRE_DOTALL
+
+If this bit is set, a dot metacharater in the pattern matches all characters, +including those that indicate newline. Without it, a dot does not match when +the current position is at a newline. This option is equivalent to Perl's /s +option, and it can be changed within a pattern by a (?s) option setting. A +negative class such as [^a] always matches newline characters, independent of +the setting of this option. +
+  PCRE_DUPNAMES
+
+If this bit is set, names used to identify capturing subpatterns need not be +unique. This can be helpful for certain types of pattern when it is known that +only one instance of the named subpattern can ever be matched. There are more +details of named subpatterns below; see also the +pcrepattern +documentation. +
+  PCRE_EXTENDED
+
+If this bit is set, whitespace data characters in the pattern are totally +ignored except when escaped or inside a character class. Whitespace does not +include the VT character (code 11). In addition, characters between an +unescaped # outside a character class and the next newline, inclusive, are also +ignored. This is equivalent to Perl's /x option, and it can be changed within a +pattern by a (?x) option setting. +

+

+This option makes it possible to include comments inside complicated patterns. +Note, however, that this applies only to data characters. Whitespace characters +may never appear within special character sequences in a pattern, for example +within the sequence (?( which introduces a conditional subpattern. +

+  PCRE_EXTRA
+
+This option was invented in order to turn on additional functionality of PCRE +that is incompatible with Perl, but it is currently of very little use. When +set, any backslash in a pattern that is followed by a letter that has no +special meaning causes an error, thus reserving these combinations for future +expansion. By default, as in Perl, a backslash followed by a letter with no +special meaning is treated as a literal. (Perl can, however, be persuaded to +give a warning for this.) There are at present no other features controlled by +this option. It can also be set by a (?X) option setting within a pattern. +
+  PCRE_FIRSTLINE
+
+If this option is set, an unanchored pattern is required to match before or at +the first newline in the subject string, though the matched text may continue +over the newline. +
+  PCRE_JAVASCRIPT_COMPAT
+
+If this option is set, PCRE's behaviour is changed in some ways so that it is +compatible with JavaScript rather than Perl. The changes are as follows: +

+

+(1) A lone closing square bracket in a pattern causes a compile-time error, +because this is illegal in JavaScript (by default it is treated as a data +character). Thus, the pattern AB]CD becomes illegal when this option is set. +

+

+(2) At run time, a back reference to an unset subpattern group matches an empty +string (by default this causes the current matching alternative to fail). A +pattern such as (\1)(a) succeeds when this option is set (assuming it can find +an "a" in the subject), whereas it fails by default, for Perl compatibility. +

+  PCRE_MULTILINE
+
+By default, PCRE treats the subject string as consisting of a single line of +characters (even if it actually contains newlines). The "start of line" +metacharacter (^) matches only at the start of the string, while the "end of +line" metacharacter ($) matches only at the end of the string, or before a +terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as +Perl. +

+

+When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs +match immediately following or immediately before internal newlines in the +subject string, respectively, as well as at the very start and end. This is +equivalent to Perl's /m option, and it can be changed within a pattern by a +(?m) option setting. If there are no newlines in a subject string, or no +occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no effect. +

+  PCRE_NEWLINE_CR
+  PCRE_NEWLINE_LF
+  PCRE_NEWLINE_CRLF
+  PCRE_NEWLINE_ANYCRLF
+  PCRE_NEWLINE_ANY
+
+These options override the default newline definition that was chosen when PCRE +was built. Setting the first or the second specifies that a newline is +indicated by a single character (CR or LF, respectively). Setting +PCRE_NEWLINE_CRLF specifies that a newline is indicated by the two-character +CRLF sequence. Setting PCRE_NEWLINE_ANYCRLF specifies that any of the three +preceding sequences should be recognized. Setting PCRE_NEWLINE_ANY specifies +that any Unicode newline sequence should be recognized. The Unicode newline +sequences are the three just mentioned, plus the single characters VT (vertical +tab, U+000B), FF (formfeed, U+000C), NEL (next line, U+0085), LS (line +separator, U+2028), and PS (paragraph separator, U+2029). The last two are +recognized only in UTF-8 mode. +

+

+The newline setting in the options word uses three bits that are treated +as a number, giving eight possibilities. Currently only six are used (default +plus the five values above). This means that if you set more than one newline +option, the combination may or may not be sensible. For example, +PCRE_NEWLINE_CR with PCRE_NEWLINE_LF is equivalent to PCRE_NEWLINE_CRLF, but +other combinations may yield unused numbers and cause an error. +

+

+The only time that a line break is specially recognized when compiling a +pattern is if PCRE_EXTENDED is set, and an unescaped # outside a character +class is encountered. This indicates a comment that lasts until after the next +line break sequence. In other circumstances, line break sequences are treated +as literal data, except that in PCRE_EXTENDED mode, both CR and LF are treated +as whitespace characters and are therefore ignored. +

+

+The newline option that is set at compile time becomes the default that is used +for pcre_exec() and pcre_dfa_exec(), but it can be overridden. +

+  PCRE_NO_AUTO_CAPTURE
+
+If this option is set, it disables the use of numbered capturing parentheses in +the pattern. Any opening parenthesis that is not followed by ? behaves as if it +were followed by ?: but named parentheses can still be used for capturing (and +they acquire numbers in the usual way). There is no equivalent of this option +in Perl. +
+  PCRE_UNGREEDY
+
+This option inverts the "greediness" of the quantifiers so that they are not +greedy by default, but become greedy if followed by "?". It is not compatible +with Perl. It can also be set by a (?U) option setting within the pattern. +
+  PCRE_UTF8
+
+This option causes PCRE to regard both the pattern and the subject as strings +of UTF-8 characters instead of single-byte character strings. However, it is +available only when PCRE is built to include UTF-8 support. If not, the use +of this option provokes an error. Details of how this option changes the +behaviour of PCRE are given in the +section on UTF-8 support +in the main +pcre +page. +
+  PCRE_NO_UTF8_CHECK
+
+When PCRE_UTF8 is set, the validity of the pattern as a UTF-8 string is +automatically checked. There is a discussion about the +validity of UTF-8 strings +in the main +pcre +page. If an invalid UTF-8 sequence of bytes is found, pcre_compile() +returns an error. If you already know that your pattern is valid, and you want +to skip this check for performance reasons, you can set the PCRE_NO_UTF8_CHECK +option. When it is set, the effect of passing an invalid UTF-8 string as a +pattern is undefined. It may cause your program to crash. Note that this option +can also be passed to pcre_exec() and pcre_dfa_exec(), to suppress +the UTF-8 validity checking of subject strings. +

+
COMPILATION ERROR CODES
+

+The following table lists the error codes than may be returned by +pcre_compile2(), along with the error messages that may be returned by +both compiling functions. As PCRE has developed, some error codes have fallen +out of use. To avoid confusion, they have not been re-used. +

+
+The numbers 32 and 10000 in errors 48 and 49 are defaults; different values may +be used if the limits were changed when PCRE was built. +

+
STUDYING A PATTERN
+

+pcre_extra *pcre_study(const pcre *code, int options +const char **errptr); +

+

+If a compiled pattern is going to be used several times, it is worth spending +more time analyzing it in order to speed up the time taken for matching. The +function pcre_study() takes a pointer to a compiled pattern as its first +argument. If studying the pattern produces additional information that will +help speed up matching, pcre_study() returns a pointer to a +pcre_extra block, in which the study_data field points to the +results of the study. +

+

+The returned value from pcre_study() can be passed directly to +pcre_exec() or pcre_dfa_exec(). However, a pcre_extra block +also contains other fields that can be set by the caller before the block is +passed; these are described +below +in the section on matching a pattern. +

+

+If studying the pattern does not produce any useful information, +pcre_study() returns NULL. In that circumstance, if the calling program +wants to pass any of the other fields to pcre_exec() or +pcre_dfa_exec(), it must set up its own pcre_extra block. +

+

+The second argument of pcre_study() contains option bits. At present, no +options are defined, and this argument should always be zero. +

+

+The third argument for pcre_study() is a pointer for an error message. If +studying succeeds (even if no data is returned), the variable it points to is +set to NULL. Otherwise it is set to point to a textual error message. This is a +static string that is part of the library. You must not try to free it. You +should test the error pointer for NULL after calling pcre_study(), to be +sure that it has run successfully. +

+

+This is a typical call to pcre_study(): +

+  pcre_extra *pe;
+  pe = pcre_study(
+    re,             /* result of pcre_compile() */
+    0,              /* no options exist */
+    &error);        /* set to NULL or points to a message */
+
+Studying a pattern does two things: first, a lower bound for the length of +subject string that is needed to match the pattern is computed. This does not +mean that there are any strings of that length that match, but it does +guarantee that no shorter strings match. The value is used by +pcre_exec() and pcre_dfa_exec() to avoid wasting time by trying to +match strings that are shorter than the lower bound. You can find out the value +in a calling program via the pcre_fullinfo() function. +

+

+Studying a pattern is also useful for non-anchored patterns that do not have a +single fixed starting character. A bitmap of possible starting bytes is +created. This speeds up finding a position in the subject at which to start +matching. +

+
LOCALE SUPPORT
+

+PCRE handles caseless matching, and determines whether characters are letters, +digits, or whatever, by reference to a set of tables, indexed by character +value. When running in UTF-8 mode, this applies only to characters with codes +less than 128. Higher-valued codes never match escapes such as \w or \d, but +can be tested with \p if PCRE is built with Unicode character property +support. The use of locales with Unicode is discouraged. If you are handling +characters with codes greater than 128, you should either use UTF-8 and +Unicode, or use locales, but not try to mix the two. +

+

+PCRE contains an internal set of tables that are used when the final argument +of pcre_compile() is NULL. These are sufficient for many applications. +Normally, the internal tables recognize only ASCII characters. However, when +PCRE is built, it is possible to cause the internal tables to be rebuilt in the +default "C" locale of the local system, which may cause them to be different. +

+

+The internal tables can always be overridden by tables supplied by the +application that calls PCRE. These may be created in a different locale from +the default. As more and more applications change to using Unicode, the need +for this locale support is expected to die away. +

+

+External tables are built by calling the pcre_maketables() function, +which has no arguments, in the relevant locale. The result can then be passed +to pcre_compile() or pcre_exec() as often as necessary. For +example, to build and use tables that are appropriate for the French locale +(where accented characters with values greater than 128 are treated as letters), +the following code could be used: +

+  setlocale(LC_CTYPE, "fr_FR");
+  tables = pcre_maketables();
+  re = pcre_compile(..., tables);
+
+The locale name "fr_FR" is used on Linux and other Unix-like systems; if you +are using Windows, the name for the French locale is "french". +

+

+When pcre_maketables() runs, the tables are built in memory that is +obtained via pcre_malloc. It is the caller's responsibility to ensure +that the memory containing the tables remains available for as long as it is +needed. +

+

+The pointer that is passed to pcre_compile() is saved with the compiled +pattern, and the same tables are used via this pointer by pcre_study() +and normally also by pcre_exec(). Thus, by default, for any single +pattern, compilation, studying and matching all happen in the same locale, but +different patterns can be compiled in different locales. +

+

+It is possible to pass a table pointer or NULL (indicating the use of the +internal tables) to pcre_exec(). Although not intended for this purpose, +this facility could be used to match a pattern in a different locale from the +one in which it was compiled. Passing table pointers at run time is discussed +below in the section on matching a pattern. +

+
INFORMATION ABOUT A PATTERN
+

+int pcre_fullinfo(const pcre *code, const pcre_extra *extra, +int what, void *where); +

+

+The pcre_fullinfo() function returns information about a compiled +pattern. It replaces the obsolete pcre_info() function, which is +nevertheless retained for backwards compability (and is documented below). +

+

+The first argument for pcre_fullinfo() is a pointer to the compiled +pattern. The second argument is the result of pcre_study(), or NULL if +the pattern was not studied. The third argument specifies which piece of +information is required, and the fourth argument is a pointer to a variable +to receive the data. The yield of the function is zero for success, or one of +the following negative numbers: +

+  PCRE_ERROR_NULL       the argument code was NULL
+                        the argument where was NULL
+  PCRE_ERROR_BADMAGIC   the "magic number" was not found
+  PCRE_ERROR_BADOPTION  the value of what was invalid
+
+The "magic number" is placed at the start of each compiled pattern as an simple +check against passing an arbitrary memory pointer. Here is a typical call of +pcre_fullinfo(), to obtain the length of the compiled pattern: +
+  int rc;
+  size_t length;
+  rc = pcre_fullinfo(
+    re,               /* result of pcre_compile() */
+    pe,               /* result of pcre_study(), or NULL */
+    PCRE_INFO_SIZE,   /* what is required */
+    &length);         /* where to put the data */
+
+The possible values for the third argument are defined in pcre.h, and are +as follows: +
+  PCRE_INFO_BACKREFMAX
+
+Return the number of the highest back reference in the pattern. The fourth +argument should point to an int variable. Zero is returned if there are +no back references. +
+  PCRE_INFO_CAPTURECOUNT
+
+Return the number of capturing subpatterns in the pattern. The fourth argument +should point to an int variable. +
+  PCRE_INFO_DEFAULT_TABLES
+
+Return a pointer to the internal default character tables within PCRE. The +fourth argument should point to an unsigned char * variable. This +information call is provided for internal use by the pcre_study() +function. External callers can cause PCRE to use its internal tables by passing +a NULL table pointer. +
+  PCRE_INFO_FIRSTBYTE
+
+Return information about the first byte of any matched string, for a +non-anchored pattern. The fourth argument should point to an int +variable. (This option used to be called PCRE_INFO_FIRSTCHAR; the old name is +still recognized for backwards compatibility.) +

+

+If there is a fixed first byte, for example, from a pattern such as +(cat|cow|coyote), its value is returned. Otherwise, if either +
+
+(a) the pattern was compiled with the PCRE_MULTILINE option, and every branch +starts with "^", or +
+
+(b) every branch of the pattern starts with ".*" and PCRE_DOTALL is not set +(if it were set, the pattern would be anchored), +
+
+-1 is returned, indicating that the pattern matches only at the start of a +subject string or after any newline within the string. Otherwise -2 is +returned. For anchored patterns, -2 is returned. +

+  PCRE_INFO_FIRSTTABLE
+
+If the pattern was studied, and this resulted in the construction of a 256-bit +table indicating a fixed set of bytes for the first byte in any matching +string, a pointer to the table is returned. Otherwise NULL is returned. The +fourth argument should point to an unsigned char * variable. +
+  PCRE_INFO_HASCRORLF
+
+Return 1 if the pattern contains any explicit matches for CR or LF characters, +otherwise 0. The fourth argument should point to an int variable. An +explicit match is either a literal CR or LF character, or \r or \n. +
+  PCRE_INFO_JCHANGED
+
+Return 1 if the (?J) or (?-J) option setting is used in the pattern, otherwise +0. The fourth argument should point to an int variable. (?J) and +(?-J) set and unset the local PCRE_DUPNAMES option, respectively. +
+  PCRE_INFO_LASTLITERAL
+
+Return the value of the rightmost literal byte that must exist in any matched +string, other than at its start, if such a byte has been recorded. The fourth +argument should point to an int variable. If there is no such byte, -1 is +returned. For anchored patterns, a last literal byte is recorded only if it +follows something of variable length. For example, for the pattern +/^a\d+z\d+/ the returned value is "z", but for /^a\dz\d/ the returned value +is -1. +
+  PCRE_INFO_MINLENGTH
+
+If the pattern was studied and a minimum length for matching subject strings +was computed, its value is returned. Otherwise the returned value is -1. The +value is a number of characters, not bytes (this may be relevant in UTF-8 +mode). The fourth argument should point to an int variable. A +non-negative value is a lower bound to the length of any matching string. There +may not be any strings of that length that do actually match, but every string +that does match is at least that long. +
+  PCRE_INFO_NAMECOUNT
+  PCRE_INFO_NAMEENTRYSIZE
+  PCRE_INFO_NAMETABLE
+
+PCRE supports the use of named as well as numbered capturing parentheses. The +names are just an additional way of identifying the parentheses, which still +acquire numbers. Several convenience functions such as +pcre_get_named_substring() are provided for extracting captured +substrings by name. It is also possible to extract the data directly, by first +converting the name to a number in order to access the correct pointers in the +output vector (described with pcre_exec() below). To do the conversion, +you need to use the name-to-number map, which is described by these three +values. +

+

+The map consists of a number of fixed-size entries. PCRE_INFO_NAMECOUNT gives +the number of entries, and PCRE_INFO_NAMEENTRYSIZE gives the size of each +entry; both of these return an int value. The entry size depends on the +length of the longest name. PCRE_INFO_NAMETABLE returns a pointer to the first +entry of the table (a pointer to char). The first two bytes of each entry +are the number of the capturing parenthesis, most significant byte first. The +rest of the entry is the corresponding name, zero terminated. +

+

+The names are in alphabetical order. Duplicate names may appear if (?| is used +to create multiple groups with the same number, as described in the +section on duplicate subpattern numbers +in the +pcrepattern +page. Duplicate names for subpatterns with different numbers are permitted only +if PCRE_DUPNAMES is set. In all cases of duplicate names, they appear in the +table in the order in which they were found in the pattern. In the absence of +(?| this is the order of increasing number; when (?| is used this is not +necessarily the case because later subpatterns may have lower numbers. +

+

+As a simple example of the name/number table, consider the following pattern +(assume PCRE_EXTENDED is set, so white space - including newlines - is +ignored): +

+  (?<date> (?<year>(\d\d)?\d\d) - (?<month>\d\d) - (?<day>\d\d) )
+
+There are four named subpatterns, so the table has four entries, and each entry +in the table is eight bytes long. The table is as follows, with non-printing +bytes shows in hexadecimal, and undefined bytes shown as ??: +
+  00 01 d  a  t  e  00 ??
+  00 05 d  a  y  00 ?? ??
+  00 04 m  o  n  t  h  00
+  00 02 y  e  a  r  00 ??
+
+When writing code to extract data from named subpatterns using the +name-to-number map, remember that the length of the entries is likely to be +different for each compiled pattern. +
+  PCRE_INFO_OKPARTIAL
+
+Return 1 if the pattern can be used for partial matching with +pcre_exec(), otherwise 0. The fourth argument should point to an +int variable. From release 8.00, this always returns 1, because the +restrictions that previously applied to partial matching have been lifted. The +pcrepartial +documentation gives details of partial matching. +
+  PCRE_INFO_OPTIONS
+
+Return a copy of the options with which the pattern was compiled. The fourth +argument should point to an unsigned long int variable. These option bits +are those specified in the call to pcre_compile(), modified by any +top-level option settings at the start of the pattern itself. In other words, +they are the options that will be in force when matching starts. For example, +if the pattern /(?im)abc(?-i)d/ is compiled with the PCRE_EXTENDED option, the +result is PCRE_CASELESS, PCRE_MULTILINE, and PCRE_EXTENDED. +

+

+A pattern is automatically anchored by PCRE if all of its top-level +alternatives begin with one of the following: +

+  ^     unless PCRE_MULTILINE is set
+  \A    always
+  \G    always
+  .*    if PCRE_DOTALL is set and there are no back references to the subpattern in which .* appears
+
+For such patterns, the PCRE_ANCHORED bit is set in the options returned by +pcre_fullinfo(). +
+  PCRE_INFO_SIZE
+
+Return the size of the compiled pattern, that is, the value that was passed as +the argument to pcre_malloc() when PCRE was getting memory in which to +place the compiled data. The fourth argument should point to a size_t +variable. +
+  PCRE_INFO_STUDYSIZE
+
+Return the size of the data block pointed to by the study_data field in +a pcre_extra block. That is, it is the value that was passed to +pcre_malloc() when PCRE was getting memory into which to place the data +created by pcre_study(). If pcre_extra is NULL, or there is no +study data, zero is returned. The fourth argument should point to a +size_t variable. +

+
OBSOLETE INFO FUNCTION
+

+int pcre_info(const pcre *code, int *optptr, int +*firstcharptr); +

+

+The pcre_info() function is now obsolete because its interface is too +restrictive to return all the available data about a compiled pattern. New +programs should use pcre_fullinfo() instead. The yield of +pcre_info() is the number of capturing subpatterns, or one of the +following negative numbers: +

+  PCRE_ERROR_NULL       the argument code was NULL
+  PCRE_ERROR_BADMAGIC   the "magic number" was not found
+
+If the optptr argument is not NULL, a copy of the options with which the +pattern was compiled is placed in the integer it points to (see +PCRE_INFO_OPTIONS above). +

+

+If the pattern is not anchored and the firstcharptr argument is not NULL, +it is used to pass back information about the first character of any matched +string (see PCRE_INFO_FIRSTBYTE above). +

+
REFERENCE COUNTS
+

+int pcre_refcount(pcre *code, int adjust); +

+

+The pcre_refcount() function is used to maintain a reference count in the +data block that contains a compiled pattern. It is provided for the benefit of +applications that operate in an object-oriented manner, where different parts +of the application may be using the same compiled pattern, but you want to free +the block when they are all done. +

+

+When a pattern is compiled, the reference count field is initialized to zero. +It is changed only by calling this function, whose action is to add the +adjust value (which may be positive or negative) to it. The yield of the +function is the new value. However, the value of the count is constrained to +lie between 0 and 65535, inclusive. If the new value is outside these limits, +it is forced to the appropriate limit value. +

+

+Except when it is zero, the reference count is not correctly preserved if a +pattern is compiled on one host and then transferred to a host whose byte-order +is different. (This seems a highly unlikely scenario.) +

+
MATCHING A PATTERN: THE TRADITIONAL FUNCTION
+

+int pcre_exec(const pcre *code, const pcre_extra *extra, +const char *subject, int length, int startoffset, +int options, int *ovector, int ovecsize); +

+

+The function pcre_exec() is called to match a subject string against a +compiled pattern, which is passed in the code argument. If the +pattern was studied, the result of the study should be passed in the +extra argument. This function is the main matching facility of the +library, and it operates in a Perl-like manner. For specialist use there is +also an alternative matching function, which is described +below +in the section about the pcre_dfa_exec() function. +

+

+In most applications, the pattern will have been compiled (and optionally +studied) in the same process that calls pcre_exec(). However, it is +possible to save compiled patterns and study data, and then use them later +in different processes, possibly even on different hosts. For a discussion +about this, see the +pcreprecompile +documentation. +

+

+Here is an example of a simple call to pcre_exec(): +

+  int rc;
+  int ovector[30];
+  rc = pcre_exec(
+    re,             /* result of pcre_compile() */
+    NULL,           /* we didn't study the pattern */
+    "some string",  /* the subject string */
+    11,             /* the length of the subject string */
+    0,              /* start at offset 0 in the subject */
+    0,              /* default options */
+    ovector,        /* vector of integers for substring information */
+    30);            /* number of elements (NOT size in bytes) */
+
+

+
+Extra data for pcre_exec() +
+

+If the extra argument is not NULL, it must point to a pcre_extra +data block. The pcre_study() function returns such a block (when it +doesn't return NULL), but you can also create one for yourself, and pass +additional information in it. The pcre_extra block contains the following +fields (not necessarily in this order): +

+  unsigned long int flags;
+  void *study_data;
+  unsigned long int match_limit;
+  unsigned long int match_limit_recursion;
+  void *callout_data;
+  const unsigned char *tables;
+
+The flags field is a bitmap that specifies which of the other fields +are set. The flag bits are: +
+  PCRE_EXTRA_STUDY_DATA
+  PCRE_EXTRA_MATCH_LIMIT
+  PCRE_EXTRA_MATCH_LIMIT_RECURSION
+  PCRE_EXTRA_CALLOUT_DATA
+  PCRE_EXTRA_TABLES
+
+Other flag bits should be set to zero. The study_data field is set in the +pcre_extra block that is returned by pcre_study(), together with +the appropriate flag bit. You should not set this yourself, but you may add to +the block by setting the other fields and their corresponding flag bits. +

+

+The match_limit field provides a means of preventing PCRE from using up a +vast amount of resources when running patterns that are not going to match, +but which have a very large number of possibilities in their search trees. The +classic example is a pattern that uses nested unlimited repeats. +

+

+Internally, PCRE uses a function called match() which it calls repeatedly +(sometimes recursively). The limit set by match_limit is imposed on the +number of times this function is called during a match, which has the effect of +limiting the amount of backtracking that can take place. For patterns that are +not anchored, the count restarts from zero for each position in the subject +string. +

+

+The default value for the limit can be set when PCRE is built; the default +default is 10 million, which handles all but the most extreme cases. You can +override the default by suppling pcre_exec() with a pcre_extra +block in which match_limit is set, and PCRE_EXTRA_MATCH_LIMIT is set in +the flags field. If the limit is exceeded, pcre_exec() returns +PCRE_ERROR_MATCHLIMIT. +

+

+The match_limit_recursion field is similar to match_limit, but +instead of limiting the total number of times that match() is called, it +limits the depth of recursion. The recursion depth is a smaller number than the +total number of calls, because not all calls to match() are recursive. +This limit is of use only if it is set smaller than match_limit. +

+

+Limiting the recursion depth limits the amount of stack that can be used, or, +when PCRE has been compiled to use memory on the heap instead of the stack, the +amount of heap memory that can be used. +

+

+The default value for match_limit_recursion can be set when PCRE is +built; the default default is the same value as the default for +match_limit. You can override the default by suppling pcre_exec() +with a pcre_extra block in which match_limit_recursion is set, and +PCRE_EXTRA_MATCH_LIMIT_RECURSION is set in the flags field. If the limit +is exceeded, pcre_exec() returns PCRE_ERROR_RECURSIONLIMIT. +

+

+The callout_data field is used in conjunction with the "callout" feature, +and is described in the +pcrecallout +documentation. +

+

+The tables field is used to pass a character tables pointer to +pcre_exec(); this overrides the value that is stored with the compiled +pattern. A non-NULL value is stored with the compiled pattern only if custom +tables were supplied to pcre_compile() via its tableptr argument. +If NULL is passed to pcre_exec() using this mechanism, it forces PCRE's +internal tables to be used. This facility is helpful when re-using patterns +that have been saved after compiling with an external set of tables, because +the external tables might be at a different address when pcre_exec() is +called. See the +pcreprecompile +documentation for a discussion of saving compiled patterns for later use. +

+
+Option bits for pcre_exec() +
+

+The unused bits of the options argument for pcre_exec() must be +zero. The only bits that may be set are PCRE_ANCHORED, PCRE_NEWLINE_xxx, +PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, PCRE_NOTEMPTY_ATSTART, +PCRE_NO_START_OPTIMIZE, PCRE_NO_UTF8_CHECK, PCRE_PARTIAL_SOFT, and +PCRE_PARTIAL_HARD. +

+  PCRE_ANCHORED
+
+The PCRE_ANCHORED option limits pcre_exec() to matching at the first +matching position. If a pattern was compiled with PCRE_ANCHORED, or turned out +to be anchored by virtue of its contents, it cannot be made unachored at +matching time. +
+  PCRE_BSR_ANYCRLF
+  PCRE_BSR_UNICODE
+
+These options (which are mutually exclusive) control what the \R escape +sequence matches. The choice is either to match only CR, LF, or CRLF, or to +match any Unicode newline sequence. These options override the choice that was +made or defaulted when the pattern was compiled. +
+  PCRE_NEWLINE_CR
+  PCRE_NEWLINE_LF
+  PCRE_NEWLINE_CRLF
+  PCRE_NEWLINE_ANYCRLF
+  PCRE_NEWLINE_ANY
+
+These options override the newline definition that was chosen or defaulted when +the pattern was compiled. For details, see the description of +pcre_compile() above. During matching, the newline choice affects the +behaviour of the dot, circumflex, and dollar metacharacters. It may also alter +the way the match position is advanced after a match failure for an unanchored +pattern. +

+

+When PCRE_NEWLINE_CRLF, PCRE_NEWLINE_ANYCRLF, or PCRE_NEWLINE_ANY is set, and a +match attempt for an unanchored pattern fails when the current position is at a +CRLF sequence, and the pattern contains no explicit matches for CR or LF +characters, the match position is advanced by two characters instead of one, in +other words, to after the CRLF. +

+

+The above rule is a compromise that makes the most common cases work as +expected. For example, if the pattern is .+A (and the PCRE_DOTALL option is not +set), it does not match the string "\r\nA" because, after failing at the +start, it skips both the CR and the LF before retrying. However, the pattern +[\r\n]A does match that string, because it contains an explicit CR or LF +reference, and so advances only by one character after the first failure. +

+

+An explicit match for CR of LF is either a literal appearance of one of those +characters, or one of the \r or \n escape sequences. Implicit matches such as +[^X] do not count, nor does \s (which includes CR and LF in the characters +that it matches). +

+

+Notwithstanding the above, anomalous effects may still occur when CRLF is a +valid newline sequence and explicit \r or \n escapes appear in the pattern. +

+  PCRE_NOTBOL
+
+This option specifies that first character of the subject string is not the +beginning of a line, so the circumflex metacharacter should not match before +it. Setting this without PCRE_MULTILINE (at compile time) causes circumflex +never to match. This option affects only the behaviour of the circumflex +metacharacter. It does not affect \A. +
+  PCRE_NOTEOL
+
+This option specifies that the end of the subject string is not the end of a +line, so the dollar metacharacter should not match it nor (except in multiline +mode) a newline immediately before it. Setting this without PCRE_MULTILINE (at +compile time) causes dollar never to match. This option affects only the +behaviour of the dollar metacharacter. It does not affect \Z or \z. +
+  PCRE_NOTEMPTY
+
+An empty string is not considered to be a valid match if this option is set. If +there are alternatives in the pattern, they are tried. If all the alternatives +match the empty string, the entire match fails. For example, if the pattern +
+  a?b?
+
+is applied to a string not beginning with "a" or "b", it matches an empty +string at the start of the subject. With PCRE_NOTEMPTY set, this match is not +valid, so PCRE searches further into the string for occurrences of "a" or "b". +
+  PCRE_NOTEMPTY_ATSTART
+
+This is like PCRE_NOTEMPTY, except that an empty string match that is not at +the start of the subject is permitted. If the pattern is anchored, such a match +can occur only if the pattern contains \K. +

+

+Perl has no direct equivalent of PCRE_NOTEMPTY or PCRE_NOTEMPTY_ATSTART, but it +does make a special case of a pattern match of the empty string within its +split() function, and when using the /g modifier. It is possible to +emulate Perl's behaviour after matching a null string by first trying the match +again at the same offset with PCRE_NOTEMPTY_ATSTART and PCRE_ANCHORED, and then +if that fails, by advancing the starting offset (see below) and trying an +ordinary match again. There is some code that demonstrates how to do this in +the +pcredemo +sample program. +

+  PCRE_NO_START_OPTIMIZE
+
+There are a number of optimizations that pcre_exec() uses at the start of +a match, in order to speed up the process. For example, if it is known that a +match must start with a specific character, it searches the subject for that +character, and fails immediately if it cannot find it, without actually running +the main matching function. When callouts are in use, these optimizations can +cause them to be skipped. This option disables the "start-up" optimizations, +causing performance to suffer, but ensuring that the callouts do occur. +
+  PCRE_NO_UTF8_CHECK
+
+When PCRE_UTF8 is set at compile time, the validity of the subject as a UTF-8 +string is automatically checked when pcre_exec() is subsequently called. +The value of startoffset is also checked to ensure that it points to the +start of a UTF-8 character. There is a discussion about the validity of UTF-8 +strings in the +section on UTF-8 support +in the main +pcre +page. If an invalid UTF-8 sequence of bytes is found, pcre_exec() returns +the error PCRE_ERROR_BADUTF8. If startoffset contains an invalid value, +PCRE_ERROR_BADUTF8_OFFSET is returned. +

+

+If you already know that your subject is valid, and you want to skip these +checks for performance reasons, you can set the PCRE_NO_UTF8_CHECK option when +calling pcre_exec(). You might want to do this for the second and +subsequent calls to pcre_exec() if you are making repeated calls to find +all the matches in a single subject string. However, you should be sure that +the value of startoffset points to the start of a UTF-8 character. When +PCRE_NO_UTF8_CHECK is set, the effect of passing an invalid UTF-8 string as a +subject, or a value of startoffset that does not point to the start of a +UTF-8 character, is undefined. Your program may crash. +

+  PCRE_PARTIAL_HARD
+  PCRE_PARTIAL_SOFT
+
+These options turn on the partial matching feature. For backwards +compatibility, PCRE_PARTIAL is a synonym for PCRE_PARTIAL_SOFT. A partial match +occurs if the end of the subject string is reached successfully, but there are +not enough subject characters to complete the match. If this happens when +PCRE_PARTIAL_HARD is set, pcre_exec() immediately returns +PCRE_ERROR_PARTIAL. Otherwise, if PCRE_PARTIAL_SOFT is set, matching continues +by testing any other alternatives. Only if they all fail is PCRE_ERROR_PARTIAL +returned (instead of PCRE_ERROR_NOMATCH). The portion of the string that +was inspected when the partial match was found is set as the first matching +string. There is a more detailed discussion in the +pcrepartial +documentation. +

+
+The string to be matched by pcre_exec() +
+

+The subject string is passed to pcre_exec() as a pointer in +subject, a length (in bytes) in length, and a starting byte offset +in startoffset. In UTF-8 mode, the byte offset must point to the start of +a UTF-8 character. Unlike the pattern string, the subject may contain binary +zero bytes. When the starting offset is zero, the search for a match starts at +the beginning of the subject, and this is by far the most common case. +

+

+A non-zero starting offset is useful when searching for another match in the +same subject by calling pcre_exec() again after a previous success. +Setting startoffset differs from just passing over a shortened string and +setting PCRE_NOTBOL in the case of a pattern that begins with any kind of +lookbehind. For example, consider the pattern +

+  \Biss\B
+
+which finds occurrences of "iss" in the middle of words. (\B matches only if +the current position in the subject is not a word boundary.) When applied to +the string "Mississipi" the first call to pcre_exec() finds the first +occurrence. If pcre_exec() is called again with just the remainder of the +subject, namely "issipi", it does not match, because \B is always false at the +start of the subject, which is deemed to be a word boundary. However, if +pcre_exec() is passed the entire string again, but with startoffset +set to 4, it finds the second occurrence of "iss" because it is able to look +behind the starting point to discover that it is preceded by a letter. +

+

+If a non-zero starting offset is passed when the pattern is anchored, one +attempt to match at the given offset is made. This can only succeed if the +pattern does not require the match to be at the start of the subject. +

+
+How pcre_exec() returns captured substrings +
+

+In general, a pattern matches a certain portion of the subject, and in +addition, further substrings from the subject may be picked out by parts of the +pattern. Following the usage in Jeffrey Friedl's book, this is called +"capturing" in what follows, and the phrase "capturing subpattern" is used for +a fragment of a pattern that picks out a substring. PCRE supports several other +kinds of parenthesized subpattern that do not cause substrings to be captured. +

+

+Captured substrings are returned to the caller via a vector of integers whose +address is passed in ovector. The number of elements in the vector is +passed in ovecsize, which must be a non-negative number. Note: this +argument is NOT the size of ovector in bytes. +

+

+The first two-thirds of the vector is used to pass back captured substrings, +each substring using a pair of integers. The remaining third of the vector is +used as workspace by pcre_exec() while matching capturing subpatterns, +and is not available for passing back information. The number passed in +ovecsize should always be a multiple of three. If it is not, it is +rounded down. +

+

+When a match is successful, information about captured substrings is returned +in pairs of integers, starting at the beginning of ovector, and +continuing up to two-thirds of its length at the most. The first element of +each pair is set to the byte offset of the first character in a substring, and +the second is set to the byte offset of the first character after the end of a +substring. Note: these values are always byte offsets, even in UTF-8 +mode. They are not character counts. +

+

+The first pair of integers, ovector[0] and ovector[1], identify the +portion of the subject string matched by the entire pattern. The next pair is +used for the first capturing subpattern, and so on. The value returned by +pcre_exec() is one more than the highest numbered pair that has been set. +For example, if two substrings have been captured, the returned value is 3. If +there are no capturing subpatterns, the return value from a successful match is +1, indicating that just the first pair of offsets has been set. +

+

+If a capturing subpattern is matched repeatedly, it is the last portion of the +string that it matched that is returned. +

+

+If the vector is too small to hold all the captured substring offsets, it is +used as far as possible (up to two-thirds of its length), and the function +returns a value of zero. If the substring offsets are not of interest, +pcre_exec() may be called with ovector passed as NULL and +ovecsize as zero. However, if the pattern contains back references and +the ovector is not big enough to remember the related substrings, PCRE +has to get additional memory for use during matching. Thus it is usually +advisable to supply an ovector. +

+

+The pcre_fullinfo() function can be used to find out how many capturing +subpatterns there are in a compiled pattern. The smallest size for +ovector that will allow for n captured substrings, in addition to +the offsets of the substring matched by the whole pattern, is (n+1)*3. +

+

+It is possible for capturing subpattern number n+1 to match some part of +the subject when subpattern n has not been used at all. For example, if +the string "abc" is matched against the pattern (a|(z))(bc) the return from the +function is 4, and subpatterns 1 and 3 are matched, but 2 is not. When this +happens, both values in the offset pairs corresponding to unused subpatterns +are set to -1. +

+

+Offset values that correspond to unused subpatterns at the end of the +expression are also set to -1. For example, if the string "abc" is matched +against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not matched. The +return from the function is 2, because the highest used capturing subpattern +number is 1. However, you can refer to the offsets for the second and third +capturing subpatterns if you wish (assuming the vector is large enough, of +course). +

+

+Some convenience functions are provided for extracting the captured substrings +as separate strings. These are described below. +

+
+Error return values from pcre_exec() +
+

+If pcre_exec() fails, it returns a negative number. The following are +defined in the header file: +

+  PCRE_ERROR_NOMATCH        (-1)
+
+The subject string did not match the pattern. +
+  PCRE_ERROR_NULL           (-2)
+
+Either code or subject was passed as NULL, or ovector was +NULL and ovecsize was not zero. +
+  PCRE_ERROR_BADOPTION      (-3)
+
+An unrecognized bit was set in the options argument. +
+  PCRE_ERROR_BADMAGIC       (-4)
+
+PCRE stores a 4-byte "magic number" at the start of the compiled code, to catch +the case when it is passed a junk pointer and to detect when a pattern that was +compiled in an environment of one endianness is run in an environment with the +other endianness. This is the error that PCRE gives when the magic number is +not present. +
+  PCRE_ERROR_UNKNOWN_OPCODE (-5)
+
+While running the pattern match, an unknown item was encountered in the +compiled pattern. This error could be caused by a bug in PCRE or by overwriting +of the compiled pattern. +
+  PCRE_ERROR_NOMEMORY       (-6)
+
+If a pattern contains back references, but the ovector that is passed to +pcre_exec() is not big enough to remember the referenced substrings, PCRE +gets a block of memory at the start of matching to use for this purpose. If the +call via pcre_malloc() fails, this error is given. The memory is +automatically freed at the end of matching. +
+  PCRE_ERROR_NOSUBSTRING    (-7)
+
+This error is used by the pcre_copy_substring(), +pcre_get_substring(), and pcre_get_substring_list() functions (see +below). It is never returned by pcre_exec(). +
+  PCRE_ERROR_MATCHLIMIT     (-8)
+
+The backtracking limit, as specified by the match_limit field in a +pcre_extra structure (or defaulted) was reached. See the description +above. +
+  PCRE_ERROR_CALLOUT        (-9)
+
+This error is never generated by pcre_exec() itself. It is provided for +use by callout functions that want to yield a distinctive error code. See the +pcrecallout +documentation for details. +
+  PCRE_ERROR_BADUTF8        (-10)
+
+A string that contains an invalid UTF-8 byte sequence was passed as a subject. +
+  PCRE_ERROR_BADUTF8_OFFSET (-11)
+
+The UTF-8 byte sequence that was passed as a subject was valid, but the value +of startoffset did not point to the beginning of a UTF-8 character. +
+  PCRE_ERROR_PARTIAL        (-12)
+
+The subject string did not match, but it did match partially. See the +pcrepartial +documentation for details of partial matching. +
+  PCRE_ERROR_BADPARTIAL     (-13)
+
+This code is no longer in use. It was formerly returned when the PCRE_PARTIAL +option was used with a compiled pattern containing items that were not +supported for partial matching. From release 8.00 onwards, there are no +restrictions on partial matching. +
+  PCRE_ERROR_INTERNAL       (-14)
+
+An unexpected internal error has occurred. This error could be caused by a bug +in PCRE or by overwriting of the compiled pattern. +
+  PCRE_ERROR_BADCOUNT       (-15)
+
+This error is given if the value of the ovecsize argument is negative. +
+  PCRE_ERROR_RECURSIONLIMIT (-21)
+
+The internal recursion limit, as specified by the match_limit_recursion +field in a pcre_extra structure (or defaulted) was reached. See the +description above. +
+  PCRE_ERROR_BADNEWLINE     (-23)
+
+An invalid combination of PCRE_NEWLINE_xxx options was given. +

+

+Error numbers -16 to -20 and -22 are not used by pcre_exec(). +

+
EXTRACTING CAPTURED SUBSTRINGS BY NUMBER
+

+int pcre_copy_substring(const char *subject, int *ovector, +int stringcount, int stringnumber, char *buffer, +int buffersize); +

+

+int pcre_get_substring(const char *subject, int *ovector, +int stringcount, int stringnumber, +const char **stringptr); +

+

+int pcre_get_substring_list(const char *subject, +int *ovector, int stringcount, const char ***listptr); +

+

+Captured substrings can be accessed directly by using the offsets returned by +pcre_exec() in ovector. For convenience, the functions +pcre_copy_substring(), pcre_get_substring(), and +pcre_get_substring_list() are provided for extracting captured substrings +as new, separate, zero-terminated strings. These functions identify substrings +by number. The next section describes functions for extracting named +substrings. +

+

+A substring that contains a binary zero is correctly extracted and has a +further zero added on the end, but the result is not, of course, a C string. +However, you can process such a string by referring to the length that is +returned by pcre_copy_substring() and pcre_get_substring(). +Unfortunately, the interface to pcre_get_substring_list() is not adequate +for handling strings containing binary zeros, because the end of the final +string is not independently indicated. +

+

+The first three arguments are the same for all three of these functions: +subject is the subject string that has just been successfully matched, +ovector is a pointer to the vector of integer offsets that was passed to +pcre_exec(), and stringcount is the number of substrings that were +captured by the match, including the substring that matched the entire regular +expression. This is the value returned by pcre_exec() if it is greater +than zero. If pcre_exec() returned zero, indicating that it ran out of +space in ovector, the value passed as stringcount should be the +number of elements in the vector divided by three. +

+

+The functions pcre_copy_substring() and pcre_get_substring() +extract a single substring, whose number is given as stringnumber. A +value of zero extracts the substring that matched the entire pattern, whereas +higher values extract the captured substrings. For pcre_copy_substring(), +the string is placed in buffer, whose length is given by +buffersize, while for pcre_get_substring() a new block of memory is +obtained via pcre_malloc, and its address is returned via +stringptr. The yield of the function is the length of the string, not +including the terminating zero, or one of these error codes: +

+  PCRE_ERROR_NOMEMORY       (-6)
+
+The buffer was too small for pcre_copy_substring(), or the attempt to get +memory failed for pcre_get_substring(). +
+  PCRE_ERROR_NOSUBSTRING    (-7)
+
+There is no substring whose number is stringnumber. +

+

+The pcre_get_substring_list() function extracts all available substrings +and builds a list of pointers to them. All this is done in a single block of +memory that is obtained via pcre_malloc. The address of the memory block +is returned via listptr, which is also the start of the list of string +pointers. The end of the list is marked by a NULL pointer. The yield of the +function is zero if all went well, or the error code +

+  PCRE_ERROR_NOMEMORY       (-6)
+
+if the attempt to get the memory block failed. +

+

+When any of these functions encounter a substring that is unset, which can +happen when capturing subpattern number n+1 matches some part of the +subject, but subpattern n has not been used at all, they return an empty +string. This can be distinguished from a genuine zero-length substring by +inspecting the appropriate offset in ovector, which is negative for unset +substrings. +

+

+The two convenience functions pcre_free_substring() and +pcre_free_substring_list() can be used to free the memory returned by +a previous call of pcre_get_substring() or +pcre_get_substring_list(), respectively. They do nothing more than call +the function pointed to by pcre_free, which of course could be called +directly from a C program. However, PCRE is used in some situations where it is +linked via a special interface to another programming language that cannot use +pcre_free directly; it is for these cases that the functions are +provided. +

+
EXTRACTING CAPTURED SUBSTRINGS BY NAME
+

+int pcre_get_stringnumber(const pcre *code, +const char *name); +

+

+int pcre_copy_named_substring(const pcre *code, +const char *subject, int *ovector, +int stringcount, const char *stringname, +char *buffer, int buffersize); +

+

+int pcre_get_named_substring(const pcre *code, +const char *subject, int *ovector, +int stringcount, const char *stringname, +const char **stringptr); +

+

+To extract a substring by name, you first have to find associated number. +For example, for this pattern +

+  (a+)b(?<xxx>\d+)...
+
+the number of the subpattern called "xxx" is 2. If the name is known to be +unique (PCRE_DUPNAMES was not set), you can find the number from the name by +calling pcre_get_stringnumber(). The first argument is the compiled +pattern, and the second is the name. The yield of the function is the +subpattern number, or PCRE_ERROR_NOSUBSTRING (-7) if there is no subpattern of +that name. +

+

+Given the number, you can extract the substring directly, or use one of the +functions described in the previous section. For convenience, there are also +two functions that do the whole job. +

+

+Most of the arguments of pcre_copy_named_substring() and +pcre_get_named_substring() are the same as those for the similarly named +functions that extract by number. As these are described in the previous +section, they are not re-described here. There are just two differences: +

+

+First, instead of a substring number, a substring name is given. Second, there +is an extra argument, given at the start, which is a pointer to the compiled +pattern. This is needed in order to gain access to the name-to-number +translation table. +

+

+These functions call pcre_get_stringnumber(), and if it succeeds, they +then call pcre_copy_substring() or pcre_get_substring(), as +appropriate. NOTE: If PCRE_DUPNAMES is set and there are duplicate names, +the behaviour may not be what you want (see the next section). +

+

+Warning: If the pattern uses the (?| feature to set up multiple +subpatterns with the same number, as described in the +section on duplicate subpattern numbers +in the +pcrepattern +page, you cannot use names to distinguish the different subpatterns, because +names are not included in the compiled code. The matching process uses only +numbers. For this reason, the use of different names for subpatterns of the +same number causes an error at compile time. +

+
DUPLICATE SUBPATTERN NAMES
+

+int pcre_get_stringtable_entries(const pcre *code, +const char *name, char **first, char **last); +

+

+When a pattern is compiled with the PCRE_DUPNAMES option, names for subpatterns +are not required to be unique. (Duplicate names are always allowed for +subpatterns with the same number, created by using the (?| feature. Indeed, if +such subpatterns are named, they are required to use the same names.) +

+

+Normally, patterns with duplicate names are such that in any one match, only +one of the named subpatterns participates. An example is shown in the +pcrepattern +documentation. +

+

+When duplicates are present, pcre_copy_named_substring() and +pcre_get_named_substring() return the first substring corresponding to +the given name that is set. If none are set, PCRE_ERROR_NOSUBSTRING (-7) is +returned; no data is returned. The pcre_get_stringnumber() function +returns one of the numbers that are associated with the name, but it is not +defined which it is. +

+

+If you want to get full details of all captured substrings for a given name, +you must use the pcre_get_stringtable_entries() function. The first +argument is the compiled pattern, and the second is the name. The third and +fourth are pointers to variables which are updated by the function. After it +has run, they point to the first and last entries in the name-to-number table +for the given name. The function itself returns the length of each entry, or +PCRE_ERROR_NOSUBSTRING (-7) if there are none. The format of the table is +described above in the section entitled Information about a pattern. +Given all the relevant entries for the name, you can extract each of their +numbers, and hence the captured data, if any. +

+
FINDING ALL POSSIBLE MATCHES
+

+The traditional matching function uses a similar algorithm to Perl, which stops +when it finds the first match, starting at a given point in the subject. If you +want to find all possible matches, or the longest possible match, consider +using the alternative matching function (see below) instead. If you cannot use +the alternative function, but still need to find all possible matches, you +can kludge it up by making use of the callout facility, which is described in +the +pcrecallout +documentation. +

+

+What you have to do is to insert a callout right at the end of the pattern. +When your callout function is called, extract and save the current matched +substring. Then return 1, which forces pcre_exec() to backtrack and try +other alternatives. Ultimately, when it runs out of matches, pcre_exec() +will yield PCRE_ERROR_NOMATCH. +

+
MATCHING A PATTERN: THE ALTERNATIVE FUNCTION
+

+int pcre_dfa_exec(const pcre *code, const pcre_extra *extra, +const char *subject, int length, int startoffset, +int options, int *ovector, int ovecsize, +int *workspace, int wscount); +

+

+The function pcre_dfa_exec() is called to match a subject string against +a compiled pattern, using a matching algorithm that scans the subject string +just once, and does not backtrack. This has different characteristics to the +normal algorithm, and is not compatible with Perl. Some of the features of PCRE +patterns are not supported. Nevertheless, there are times when this kind of +matching can be useful. For a discussion of the two matching algorithms, and a +list of features that pcre_dfa_exec() does not support, see the +pcrematching +documentation. +

+

+The arguments for the pcre_dfa_exec() function are the same as for +pcre_exec(), plus two extras. The ovector argument is used in a +different way, and this is described below. The other common arguments are used +in the same way as for pcre_exec(), so their description is not repeated +here. +

+

+The two additional arguments provide workspace for the function. The workspace +vector should contain at least 20 elements. It is used for keeping track of +multiple paths through the pattern tree. More workspace will be needed for +patterns and subjects where there are a lot of potential matches. +

+

+Here is an example of a simple call to pcre_dfa_exec(): +

+  int rc;
+  int ovector[10];
+  int wspace[20];
+  rc = pcre_dfa_exec(
+    re,             /* result of pcre_compile() */
+    NULL,           /* we didn't study the pattern */
+    "some string",  /* the subject string */
+    11,             /* the length of the subject string */
+    0,              /* start at offset 0 in the subject */
+    0,              /* default options */
+    ovector,        /* vector of integers for substring information */
+    10,             /* number of elements (NOT size in bytes) */
+    wspace,         /* working space vector */
+    20);            /* number of elements (NOT size in bytes) */
+
+

+
+Option bits for pcre_dfa_exec() +
+

+The unused bits of the options argument for pcre_dfa_exec() must be +zero. The only bits that may be set are PCRE_ANCHORED, PCRE_NEWLINE_xxx, +PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, PCRE_NOTEMPTY_ATSTART, +PCRE_NO_UTF8_CHECK, PCRE_PARTIAL_HARD, PCRE_PARTIAL_SOFT, PCRE_DFA_SHORTEST, +and PCRE_DFA_RESTART. All but the last four of these are exactly the same as +for pcre_exec(), so their description is not repeated here. +

+  PCRE_PARTIAL_HARD
+  PCRE_PARTIAL_SOFT
+
+These have the same general effect as they do for pcre_exec(), but the +details are slightly different. When PCRE_PARTIAL_HARD is set for +pcre_dfa_exec(), it returns PCRE_ERROR_PARTIAL if the end of the subject +is reached and there is still at least one matching possibility that requires +additional characters. This happens even if some complete matches have also +been found. When PCRE_PARTIAL_SOFT is set, the return code PCRE_ERROR_NOMATCH +is converted into PCRE_ERROR_PARTIAL if the end of the subject is reached, +there have been no complete matches, but there is still at least one matching +possibility. The portion of the string that was inspected when the longest +partial match was found is set as the first matching string in both cases. +
+  PCRE_DFA_SHORTEST
+
+Setting the PCRE_DFA_SHORTEST option causes the matching algorithm to stop as +soon as it has found one match. Because of the way the alternative algorithm +works, this is necessarily the shortest possible match at the first possible +matching point in the subject string. +
+  PCRE_DFA_RESTART
+
+When pcre_dfa_exec() returns a partial match, it is possible to call it +again, with additional subject characters, and have it continue with the same +match. The PCRE_DFA_RESTART option requests this action; when it is set, the +workspace and wscount options must reference the same vector as +before because data about the match so far is left in them after a partial +match. There is more discussion of this facility in the +pcrepartial +documentation. +

+
+Successful returns from pcre_dfa_exec() +
+

+When pcre_dfa_exec() succeeds, it may have matched more than one +substring in the subject. Note, however, that all the matches from one run of +the function start at the same point in the subject. The shorter matches are +all initial substrings of the longer matches. For example, if the pattern +

+  <.*>
+
+is matched against the string +
+  This is <something> <something else> <something further> no more
+
+the three matched strings are +
+  <something>
+  <something> <something else>
+  <something> <something else> <something further>
+
+On success, the yield of the function is a number greater than zero, which is +the number of matched substrings. The substrings themselves are returned in +ovector. Each string uses two elements; the first is the offset to the +start, and the second is the offset to the end. In fact, all the strings have +the same start offset. (Space could have been saved by giving this only once, +but it was decided to retain some compatibility with the way pcre_exec() +returns data, even though the meaning of the strings is different.) +

+

+The strings are returned in reverse order of length; that is, the longest +matching string is given first. If there were too many matches to fit into +ovector, the yield of the function is zero, and the vector is filled with +the longest matches. +

+
+Error returns from pcre_dfa_exec() +
+

+The pcre_dfa_exec() function returns a negative number when it fails. +Many of the errors are the same as for pcre_exec(), and these are +described +above. +There are in addition the following errors that are specific to +pcre_dfa_exec(): +

+  PCRE_ERROR_DFA_UITEM      (-16)
+
+This return is given if pcre_dfa_exec() encounters an item in the pattern +that it does not support, for instance, the use of \C or a back reference. +
+  PCRE_ERROR_DFA_UCOND      (-17)
+
+This return is given if pcre_dfa_exec() encounters a condition item that +uses a back reference for the condition, or a test for recursion in a specific +group. These are not supported. +
+  PCRE_ERROR_DFA_UMLIMIT    (-18)
+
+This return is given if pcre_dfa_exec() is called with an extra +block that contains a setting of the match_limit field. This is not +supported (it is meaningless). +
+  PCRE_ERROR_DFA_WSSIZE     (-19)
+
+This return is given if pcre_dfa_exec() runs out of space in the +workspace vector. +
+  PCRE_ERROR_DFA_RECURSE    (-20)
+
+When a recursive subpattern is processed, the matching function calls itself +recursively, using private vectors for ovector and workspace. This +error is given if the output vector is not large enough. This should be +extremely rare, as a vector of size 1000 is used. +

+
PCRE BUILD-TIME OPTIONS
+

+This document describes the optional features of PCRE that can be selected when +the library is compiled. It assumes use of the configure script, where +the optional features are selected or deselected by providing options to +configure before running the make command. However, the same +options can be selected in both Unix-like and non-Unix-like environments using +the GUI facility of cmake-gui if you are using CMake instead of +configure to build PCRE. +

+

+There is a lot more information about building PCRE in non-Unix-like +environments in the file called NON_UNIX_USE, which is part of the PCRE +distribution. You should consult this file as well as the README file if +you are building in a non-Unix-like environment. +

+

+The complete list of options for configure (which includes the standard +ones such as the selection of the installation directory) can be obtained by +running +

+  ./configure --help
+
+The following sections include descriptions of options whose names begin with +--enable or --disable. These settings specify changes to the defaults for the +configure command. Because of the way that configure works, +--enable and --disable always come in pairs, so the complementary option always +exists as well, but as it specifies the default, it is not described. +

+
C++ SUPPORT
+

+By default, the configure script will search for a C++ compiler and C++ +header files. If it finds them, it automatically builds the C++ wrapper library +for PCRE. You can disable this by adding +

+  --disable-cpp
+
+to the configure command. +

+
UTF-8 SUPPORT
+

+To build PCRE with support for UTF-8 Unicode character strings, add +

+  --enable-utf8
+
+to the configure command. Of itself, this does not make PCRE treat +strings as UTF-8. As well as compiling PCRE with this option, you also have +have to set the PCRE_UTF8 option when you call the pcre_compile() +or pcre_compile2() functions. +

+

+If you set --enable-utf8 when compiling in an EBCDIC environment, PCRE expects +its input to be either ASCII or UTF-8 (depending on the runtime option). It is +not possible to support both EBCDIC and UTF-8 codes in the same version of the +library. Consequently, --enable-utf8 and --enable-ebcdic are mutually +exclusive. +

+
UNICODE CHARACTER PROPERTY SUPPORT
+

+UTF-8 support allows PCRE to process character values greater than 255 in the +strings that it handles. On its own, however, it does not provide any +facilities for accessing the properties of such characters. If you want to be +able to use the pattern escapes \P, \p, and \X, which refer to Unicode +character properties, you must add +

+  --enable-unicode-properties
+
+to the configure command. This implies UTF-8 support, even if you have +not explicitly requested it. +

+

+Including Unicode property support adds around 30K of tables to the PCRE +library. Only the general category properties such as Lu and Nd are +supported. Details are given in the +pcrepattern +documentation. +

+
CODE VALUE OF NEWLINE
+

+By default, PCRE interprets the linefeed (LF) character as indicating the end +of a line. This is the normal newline character on Unix-like systems. You can +compile PCRE to use carriage return (CR) instead, by adding +

+  --enable-newline-is-cr
+
+to the configure command. There is also a --enable-newline-is-lf option, +which explicitly specifies linefeed as the newline character. +
+
+Alternatively, you can specify that line endings are to be indicated by the two +character sequence CRLF. If you want this, add +
+  --enable-newline-is-crlf
+
+to the configure command. There is a fourth option, specified by +
+  --enable-newline-is-anycrlf
+
+which causes PCRE to recognize any of the three sequences CR, LF, or CRLF as +indicating a line ending. Finally, a fifth option, specified by +
+  --enable-newline-is-any
+
+causes PCRE to recognize any Unicode newline sequence. +

+

+Whatever line ending convention is selected when PCRE is built can be +overridden when the library functions are called. At build time it is +conventional to use the standard for your operating system. +

+
WHAT \R MATCHES
+

+By default, the sequence \R in a pattern matches any Unicode newline sequence, +whatever has been selected as the line ending sequence. If you specify +

+  --enable-bsr-anycrlf
+
+the default is changed so that \R matches only CR, LF, or CRLF. Whatever is +selected when PCRE is built can be overridden when the library functions are +called. +

+
BUILDING SHARED AND STATIC LIBRARIES
+

+The PCRE building process uses libtool to build both shared and static +Unix libraries by default. You can suppress one of these by adding one of +

+  --disable-shared
+  --disable-static
+
+to the configure command, as required. +

+
POSIX MALLOC USAGE
+

+When PCRE is called through the POSIX interface (see the +pcreposix +documentation), additional working storage is required for holding the pointers +to capturing substrings, because PCRE requires three integers per substring, +whereas the POSIX interface provides only two. If the number of expected +substrings is small, the wrapper function uses space on the stack, because this +is faster than using malloc() for each call. The default threshold above +which the stack is no longer used is 10; it can be changed by adding a setting +such as +

+  --with-posix-malloc-threshold=20
+
+to the configure command. +

+
HANDLING VERY LARGE PATTERNS
+

+Within a compiled pattern, offset values are used to point from one part to +another (for example, from an opening parenthesis to an alternation +metacharacter). By default, two-byte values are used for these offsets, leading +to a maximum size for a compiled pattern of around 64K. This is sufficient to +handle all but the most gigantic patterns. Nevertheless, some people do want to +process truyl enormous patterns, so it is possible to compile PCRE to use +three-byte or four-byte offsets by adding a setting such as +

+  --with-link-size=3
+
+to the configure command. The value given must be 2, 3, or 4. Using +longer offsets slows down the operation of PCRE because it has to load +additional bytes when handling them. +

+
AVOIDING EXCESSIVE STACK USAGE
+

+When matching with the pcre_exec() function, PCRE implements backtracking +by making recursive calls to an internal function called match(). In +environments where the size of the stack is limited, this can severely limit +PCRE's operation. (The Unix environment does not usually suffer from this +problem, but it may sometimes be necessary to increase the maximum stack size. +There is a discussion in the +pcrestack +documentation.) An alternative approach to recursion that uses memory from the +heap to remember data, instead of using recursive function calls, has been +implemented to work round the problem of limited stack size. If you want to +build a version of PCRE that works this way, add +

+  --disable-stack-for-recursion
+
+to the configure command. With this configuration, PCRE will use the +pcre_stack_malloc and pcre_stack_free variables to call memory +management functions. By default these point to malloc() and +free(), but you can replace the pointers so that your own functions are +used instead. +

+

+Separate functions are provided rather than using pcre_malloc and +pcre_free because the usage is very predictable: the block sizes +requested are always the same, and the blocks are always freed in reverse +order. A calling program might be able to implement optimized functions that +perform better than malloc() and free(). PCRE runs noticeably more +slowly when built in this way. This option affects only the pcre_exec() +function; it is not relevant for pcre_dfa_exec(). +

+
LIMITING PCRE RESOURCE USAGE
+

+Internally, PCRE has a function called match(), which it calls repeatedly +(sometimes recursively) when matching a pattern with the pcre_exec() +function. By controlling the maximum number of times this function may be +called during a single matching operation, a limit can be placed on the +resources used by a single call to pcre_exec(). The limit can be changed +at run time, as described in the +pcreapi +documentation. The default is 10 million, but this can be changed by adding a +setting such as +

+  --with-match-limit=500000
+
+to the configure command. This setting has no effect on the +pcre_dfa_exec() matching function. +

+

+In some environments it is desirable to limit the depth of recursive calls of +match() more strictly than the total number of calls, in order to +restrict the maximum amount of stack (or heap, if --disable-stack-for-recursion +is specified) that is used. A second limit controls this; it defaults to the +value that is set for --with-match-limit, which imposes no additional +constraints. However, you can set a lower limit by adding, for example, +

+  --with-match-limit-recursion=10000
+
+to the configure command. This value can also be overridden at run time. +

+
CREATING CHARACTER TABLES AT BUILD TIME
+

+PCRE uses fixed tables for processing characters whose code values are less +than 256. By default, PCRE is built with a set of tables that are distributed +in the file pcre_chartables.c.dist. These tables are for ASCII codes +only. If you add +

+  --enable-rebuild-chartables
+
+to the configure command, the distributed tables are no longer used. +Instead, a program called dftables is compiled and run. This outputs the +source for new set of tables, created in the default locale of your C runtime +system. (This method of replacing the tables does not work if you are cross +compiling, because dftables is run on the local host. If you need to +create alternative tables when cross compiling, you will have to do so "by +hand".) +

+
USING EBCDIC CODE
+

+PCRE assumes by default that it will run in an environment where the character +code is ASCII (or Unicode, which is a superset of ASCII). This is the case for +most computer operating systems. PCRE can, however, be compiled to run in an +EBCDIC environment by adding +

+  --enable-ebcdic
+
+to the configure command. This setting implies +--enable-rebuild-chartables. You should only use it if you know that you are in +an EBCDIC environment (for example, an IBM mainframe operating system). The +--enable-ebcdic option is incompatible with --enable-utf8. +

+
PCREGREP OPTIONS FOR COMPRESSED FILE SUPPORT
+

+By default, pcregrep reads all files as plain text. You can build it so +that it recognizes files whose names end in .gz or .bz2, and reads +them with libz or libbz2, respectively, by adding one or both of +

+  --enable-pcregrep-libz
+  --enable-pcregrep-libbz2
+
+to the configure command. These options naturally require that the +relevant libraries are installed on your system. Configuration will fail if +they are not. +

+
PCRETEST OPTION FOR LIBREADLINE SUPPORT
+

+If you add +

+  --enable-pcretest-libreadline
+
+to the configure command, pcretest is linked with the +libreadline library, and when its input is from a terminal, it reads it +using the readline() function. This provides line-editing and history +facilities. Note that libreadline is GPL-licensed, so if you distribute a +binary of pcretest linked in this way, there may be licensing issues. +

+

+Setting this option causes the -lreadline option to be added to the +pcretest build. In many operating environments with a sytem-installed +libreadline this is sufficient. However, in some environments (e.g. +if an unmodified distribution version of readline is in use), some extra +configuration may be necessary. The INSTALL file for libreadline says +this: +

+  "Readline uses the termcap functions, but does not link with the
+  termcap or curses library itself, allowing applications which link
+  with readline the to choose an appropriate library."
+
+If your environment has not been set up so that an appropriate library is +automatically included, you may need to add something like +
+  LIBS="-ncurses"
+
+immediately before the configure command. +

+
PCRE CALLOUTS
+

+int (*pcre_callout)(pcre_callout_block *); +

+

+PCRE provides a feature called "callout", which is a means of temporarily +passing control to the caller of PCRE in the middle of pattern matching. The +caller of PCRE provides an external function by putting its entry point in the +global variable pcre_callout. By default, this variable contains NULL, +which disables all calling out. +

+

+Within a regular expression, (?C) indicates the points at which the external +function is to be called. Different callout points can be identified by putting +a number less than 256 after the letter C. The default value is zero. +For example, this pattern has two callout points: +

+  (?C1)abc(?C2)def
+
+If the PCRE_AUTO_CALLOUT option bit is set when pcre_compile() or +pcre_compile2() is called, PCRE automatically inserts callouts, all with +number 255, before each item in the pattern. For example, if PCRE_AUTO_CALLOUT +is used with the pattern +
+  A(\d{2}|--)
+
+it is processed as if it were +
+
+(?C255)A(?C255)((?C255)\d{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255) +
+
+Notice that there is a callout before and after each parenthesis and +alternation bar. Automatic callouts can be used for tracking the progress of +pattern matching. The +pcretest +command has an option that sets automatic callouts; when it is used, the output +indicates how the pattern is matched. This is useful information when you are +trying to optimize the performance of a particular pattern. +

+
MISSING CALLOUTS
+

+You should be aware that, because of optimizations in the way PCRE matches +patterns by default, callouts sometimes do not happen. For example, if the +pattern is +

+  ab(?C4)cd
+
+PCRE knows that any matching string must contain the letter "d". If the subject +string is "abyz", the lack of "d" means that matching doesn't ever start, and +the callout is never reached. However, with "abyd", though the result is still +no match, the callout is obeyed. +

+

+If the pattern is studied, PCRE knows the minimum length of a matching string, +and will immediately give a "no match" return without actually running a match +if the subject is not long enough, or, for unanchored patterns, if it has +been scanned far enough. +

+

+You can disable these optimizations by passing the PCRE_NO_START_OPTIMIZE +option to pcre_exec() or pcre_dfa_exec(). This slows down the +matching process, but does ensure that callouts such as the example above are +obeyed. +

+
THE CALLOUT INTERFACE
+

+During matching, when PCRE reaches a callout point, the external function +defined by pcre_callout is called (if it is set). This applies to both +the pcre_exec() and the pcre_dfa_exec() matching functions. The +only argument to the callout function is a pointer to a pcre_callout +block. This structure contains the following fields: +

+  int          version;
+  int          callout_number;
+  int         *offset_vector;
+  const char  *subject;
+  int          subject_length;
+  int          start_match;
+  int          current_position;
+  int          capture_top;
+  int          capture_last;
+  void        *callout_data;
+  int          pattern_position;
+  int          next_item_length;
+
+The version field is an integer containing the version number of the +block format. The initial version was 0; the current version is 1. The version +number will change again in future if additional fields are added, but the +intention is never to remove any of the existing fields. +

+

+The callout_number field contains the number of the callout, as compiled +into the pattern (that is, the number after ?C for manual callouts, and 255 for +automatically generated callouts). +

+

+The offset_vector field is a pointer to the vector of offsets that was +passed by the caller to pcre_exec() or pcre_dfa_exec(). When +pcre_exec() is used, the contents can be inspected in order to extract +substrings that have been matched so far, in the same way as for extracting +substrings after a match has completed. For pcre_dfa_exec() this field is +not useful. +

+

+The subject and subject_length fields contain copies of the values +that were passed to pcre_exec(). +

+

+The start_match field normally contains the offset within the subject at +which the current match attempt started. However, if the escape sequence \K +has been encountered, this value is changed to reflect the modified starting +point. If the pattern is not anchored, the callout function may be called +several times from the same point in the pattern for different starting points +in the subject. +

+

+The current_position field contains the offset within the subject of the +current match pointer. +

+

+When the pcre_exec() function is used, the capture_top field +contains one more than the number of the highest numbered captured substring so +far. If no substrings have been captured, the value of capture_top is +one. This is always the case when pcre_dfa_exec() is used, because it +does not support captured substrings. +

+

+The capture_last field contains the number of the most recently captured +substring. If no substrings have been captured, its value is -1. This is always +the case when pcre_dfa_exec() is used. +

+

+The callout_data field contains a value that is passed to +pcre_exec() or pcre_dfa_exec() specifically so that it can be +passed back in callouts. It is passed in the pcre_callout field of the +pcre_extra data structure. If no such data was passed, the value of +callout_data in a pcre_callout block is NULL. There is a +description of the pcre_extra structure in the +pcreapi +documentation. +

+

+The pattern_position field is present from version 1 of the +pcre_callout structure. It contains the offset to the next item to be +matched in the pattern string. +

+

+The next_item_length field is present from version 1 of the +pcre_callout structure. It contains the length of the next item to be +matched in the pattern string. When the callout immediately precedes an +alternation bar, a closing parenthesis, or the end of the pattern, the length +is zero. When the callout precedes an opening parenthesis, the length is that +of the entire subpattern. +

+

+The pattern_position and next_item_length fields are intended to +help in distinguishing between different automatic callouts, which all have the +same callout number. However, they are set for all callouts. +

+
RETURN VALUES
+

+The external callout function returns an integer to PCRE. If the value is zero, +matching proceeds as normal. If the value is greater than zero, matching fails +at the current point, but the testing of other matching possibilities goes +ahead, just as if a lookahead assertion had failed. If the value is less than +zero, the match is abandoned, and pcre_exec() or pcre_dfa_exec() +returns the negative value. +

+

+Negative values should normally be chosen from the set of PCRE_ERROR_xxx +values. In particular, PCRE_ERROR_NOMATCH forces a standard "no match" failure. +The error number PCRE_ERROR_CALLOUT is reserved for use by callout functions; +it will never be used by PCRE itself. +

+
+DIFFERENCES BETWEEN PCRE AND PERL +
+

+This document describes the differences in the ways that PCRE and Perl handle +regular expressions. The differences described here are with respect to Perl +5.10. +

+

+1. PCRE has only a subset of Perl's UTF-8 and Unicode support. Details of what +it does have are given in the +section on UTF-8 support +in the main +pcre +page. +

+

+2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits +them, but they do not mean what you might think. For example, (?!a){3} does +not assert that the next three characters are not "a". It just asserts that the +next character is not "a" three times. +

+

+3. Capturing subpatterns that occur inside negative lookahead assertions are +counted, but their entries in the offsets vector are never set. Perl sets its +numerical variables from any such patterns that are matched before the +assertion fails to match something (thereby succeeding), but only if the +negative lookahead assertion contains just one branch. +

+

+4. Though binary zero characters are supported in the subject string, they are +not allowed in a pattern string because it is passed as a normal C string, +terminated by zero. The escape sequence \0 can be used in the pattern to +represent a binary zero. +

+

+5. The following Perl escape sequences are not supported: \l, \u, \L, +\U, and \N. In fact these are implemented by Perl's general string-handling +and are not part of its pattern matching engine. If any of these are +encountered by PCRE, an error is generated. +

+

+6. The Perl escape sequences \p, \P, and \X are supported only if PCRE is +built with Unicode character property support. The properties that can be +tested with \p and \P are limited to the general category properties such as +Lu and Nd, script names such as Greek or Han, and the derived properties Any +and L&. PCRE does support the Cs (surrogate) property, which Perl does not; the +Perl documentation says "Because Perl hides the need for the user to understand +the internal representation of Unicode characters, there is no need to +implement the somewhat messy concept of surrogates." +

+

+7. PCRE does support the \Q...\E escape for quoting substrings. Characters in +between are treated as literals. This is slightly different from Perl in that $ +and @ are also handled as literals inside the quotes. In Perl, they cause +variable interpolation (but of course PCRE does not have variables). Note the +following examples: +

+    Pattern            PCRE matches      Perl matches
+
+    \Qabc$xyz\E        abc$xyz           abc followed by the contents of $xyz
+    \Qabc\$xyz\E       abc\$xyz          abc\$xyz
+    \Qabc\E\$\Qxyz\E   abc$xyz           abc$xyz
+
+The \Q...\E sequence is recognized both inside and outside character classes. +

+

+8. Fairly obviously, PCRE does not support the (?{code}) and (??{code}) +constructions. However, there is support for recursive patterns. This is not +available in Perl 5.8, but it is in Perl 5.10. Also, the PCRE "callout" +feature allows an external function to be called during pattern matching. See +the +pcrecallout +documentation for details. +

+

+9. Subpatterns that are called recursively or as "subroutines" are always +treated as atomic groups in PCRE. This is like Python, but unlike Perl. There +is a discussion of an example that explains this in more detail in the +section on recursion differences from Perl +in the +pcrepattern +page. +

+

+10. There are some differences that are concerned with the settings of captured +strings when part of a pattern is repeated. For example, matching "aba" against +the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE it is set to "b". +

+

+11. PCRE does support Perl 5.10's backtracking verbs (*ACCEPT), (*FAIL), (*F), +(*COMMIT), (*PRUNE), (*SKIP), and (*THEN), but only in the forms without an +argument. PCRE does not support (*MARK). +

+

+12. PCRE's handling of duplicate subpattern numbers and duplicate subpattern +names is not as general as Perl's. This is a consequence of the fact the PCRE +works internally just with numbers, using an external table to translate +between numbers and names. In particular, a pattern such as (?|(?<a>A)|(?<b)B), +where the two capturing parentheses have the same number but different names, +is not supported, and causes an error at compile time. If it were allowed, it +would not be possible to distinguish which parentheses matched, because both +names map to capturing subpattern number 1. To avoid this confusing situation, +an error is given at compile time. +

+

+13. PCRE provides some extensions to the Perl regular expression facilities. +Perl 5.10 includes new features that are not in earlier versions of Perl, some +of which (such as named parentheses) have been in PCRE for some time. This list +is with respect to Perl 5.10: +
+
+(a) Although lookbehind assertions in PCRE must match fixed length strings, +each alternative branch of a lookbehind assertion can match a different length +of string. Perl requires them all to have the same length. +
+
+(b) If PCRE_DOLLAR_ENDONLY is set and PCRE_MULTILINE is not set, the $ +meta-character matches only at the very end of the string. +
+
+(c) If PCRE_EXTRA is set, a backslash followed by a letter with no special +meaning is faulted. Otherwise, like Perl, the backslash is quietly ignored. +(Perl can be made to issue a warning.) +
+
+(d) If PCRE_UNGREEDY is set, the greediness of the repetition quantifiers is +inverted, that is, by default they are not greedy, but if followed by a +question mark they are. +
+
+(e) PCRE_ANCHORED can be used at matching time to force a pattern to be tried +only at the first matching position in the subject string. +
+
+(f) The PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, PCRE_NOTEMPTY_ATSTART, and +PCRE_NO_AUTO_CAPTURE options for pcre_exec() have no Perl equivalents. +
+
+(g) The \R escape sequence can be restricted to match only CR, LF, or CRLF +by the PCRE_BSR_ANYCRLF option. +
+
+(h) The callout facility is PCRE-specific. +
+
+(i) The partial matching facility is PCRE-specific. +
+
+(j) Patterns compiled by PCRE can be saved and re-used at a later time, even on +different hosts that have the other endianness. +
+
+(k) The alternative matching function (pcre_dfa_exec()) matches in a +different way and is not Perl-compatible. +
+
+(l) PCRE recognizes some special sequences such as (*CR) at the start of +a pattern that set overall options that cannot be changed within the pattern. +

SYNOPSIS OF C++ WRAPPER
+

+#include <pcrecpp.h> +

+
DESCRIPTION
+

+The C++ wrapper for PCRE was provided by Google Inc. Some additional +functionality was added by Giuseppe Maxia. This brief man page was constructed +from the notes in the pcrecpp.h file, which should be consulted for +further details. +

+
MATCHING INTERFACE
+

+The "FullMatch" operation checks that supplied text matches a supplied pattern +exactly. If pointer arguments are supplied, it copies matched sub-strings that +match sub-patterns into them. +

+  Example: successful match
+     pcrecpp::RE re("h.*o");
+     re.FullMatch("hello");
+
+  Example: unsuccessful match (requires full match):
+     pcrecpp::RE re("e");
+     !re.FullMatch("hello");
+
+  Example: creating a temporary RE object:
+     pcrecpp::RE("h.*o").FullMatch("hello");
+
+You can pass in a "const char*" or a "string" for "text". The examples below +tend to use a const char*. You can, as in the different examples above, store +the RE object explicitly in a variable or use a temporary RE object. The +examples below use one mode or the other arbitrarily. Either could correctly be +used for any of these examples. +

+

+You must supply extra pointer arguments to extract matched subpieces. +

+  Example: extracts "ruby" into "s" and 1234 into "i"
+     int i;
+     string s;
+     pcrecpp::RE re("(\\w+):(\\d+)");
+     re.FullMatch("ruby:1234", &s, &i);
+
+  Example: does not try to extract any extra sub-patterns
+     re.FullMatch("ruby:1234", &s);
+
+  Example: does not try to extract into NULL
+     re.FullMatch("ruby:1234", NULL, &i);
+
+  Example: integer overflow causes failure
+     !re.FullMatch("ruby:1234567891234", NULL, &i);
+
+  Example: fails because there aren't enough sub-patterns:
+     !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s);
+
+  Example: fails because string cannot be stored in integer
+     !pcrecpp::RE("(.*)").FullMatch("ruby", &i);
+
+The provided pointer arguments can be pointers to any scalar numeric +type, or one of: +
+   string        (matched piece is copied to string)
+   StringPiece   (StringPiece is mutated to point to matched piece)
+   T             (where "bool T::ParseFrom(const char*, int)" exists)
+   NULL          (the corresponding matched sub-pattern is not copied)
+
+The function returns true iff all of the following conditions are satisfied: +
+  a. "text" matches "pattern" exactly;
+
+  b. The number of matched sub-patterns is >= number of supplied
+     pointers;
+
+  c. The "i"th argument has a suitable type for holding the
+     string captured as the "i"th sub-pattern. If you pass in
+     void * NULL for the "i"th argument, or a non-void * NULL
+     of the correct type, or pass fewer arguments than the
+     number of sub-patterns, "i"th captured sub-pattern is
+     ignored.
+
+CAVEAT: An optional sub-pattern that does not exist in the matched +string is assigned the empty string. Therefore, the following will +return false (because the empty string is not a valid number): +
+   int number;
+   pcrecpp::RE::FullMatch("abc", "[a-z]+(\\d+)?", &number);
+
+The matching interface supports at most 16 arguments per call. +If you need more, consider using the more general interface +pcrecpp::RE::DoMatch. See pcrecpp.h for the signature for +DoMatch. +

+

+NOTE: Do not use no_arg, which is used internally to mark the end of a +list of optional arguments, as a placeholder for missing arguments, as this can +lead to segfaults. +

+
QUOTING METACHARACTERS
+

+You can use the "QuoteMeta" operation to insert backslashes before all +potentially meaningful characters in a string. The returned string, used as a +regular expression, will exactly match the original string. +

+  Example:
+     string quoted = RE::QuoteMeta(unquoted);
+
+Note that it's legal to escape a character even if it has no special meaning in +a regular expression -- so this function does that. (This also makes it +identical to the perl function of the same name; see "perldoc -f quotemeta".) +For example, "1.5-2.0?" becomes "1\.5\-2\.0\?". +

+
PARTIAL MATCHES
+

+You can use the "PartialMatch" operation when you want the pattern +to match any substring of the text. +

+  Example: simple search for a string:
+     pcrecpp::RE("ell").PartialMatch("hello");
+
+  Example: find first number in a string:
+     int number;
+     pcrecpp::RE re("(\\d+)");
+     re.PartialMatch("x*100 + 20", &number);
+     assert(number == 100);
+
+

+
UTF-8 AND THE MATCHING INTERFACE
+

+By default, pattern and text are plain text, one byte per character. The UTF8 +flag, passed to the constructor, causes both pattern and string to be treated +as UTF-8 text, still a byte stream but potentially multiple bytes per +character. In practice, the text is likelier to be UTF-8 than the pattern, but +the match returned may depend on the UTF8 flag, so always use it when matching +UTF8 text. For example, "." will match one byte normally but with UTF8 set may +match up to three bytes of a multi-byte character. +

+  Example:
+     pcrecpp::RE_Options options;
+     options.set_utf8();
+     pcrecpp::RE re(utf8_pattern, options);
+     re.FullMatch(utf8_string);
+
+  Example: using the convenience function UTF8():
+     pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8());
+     re.FullMatch(utf8_string);
+
+NOTE: The UTF8 flag is ignored if pcre was not configured with the +
+      --enable-utf8 flag.
+
+

+
PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE
+

+PCRE defines some modifiers to change the behavior of the regular expression +engine. The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle to +pass such modifiers to a RE class. Currently, the following modifiers are +supported: +

+   modifier              description               Perl corresponding
+
+   PCRE_CASELESS         case insensitive match      /i
+   PCRE_MULTILINE        multiple lines match        /m
+   PCRE_DOTALL           dot matches newlines        /s
+   PCRE_DOLLAR_ENDONLY   $ matches only at end       N/A
+   PCRE_EXTRA            strict escape parsing       N/A
+   PCRE_EXTENDED         ignore whitespaces          /x
+   PCRE_UTF8             handles UTF8 chars          built-in
+   PCRE_UNGREEDY         reverses * and *?           N/A
+   PCRE_NO_AUTO_CAPTURE  disables capturing parens   N/A (*)
+
+(*) Both Perl and PCRE allow non capturing parentheses by means of the +"?:" modifier within the pattern itself. e.g. (?:ab|cd) does not +capture, while (ab|cd) does. +

+

+For a full account on how each modifier works, please check the +PCRE API reference page. +

+

+For each modifier, there are two member functions whose name is made +out of the modifier in lowercase, without the "PCRE_" prefix. For +instance, PCRE_CASELESS is handled by +

+  bool caseless()
+
+which returns true if the modifier is set, and +
+  RE_Options & set_caseless(bool)
+
+which sets or unsets the modifier. Moreover, PCRE_EXTRA_MATCH_LIMIT can be +accessed through the set_match_limit() and match_limit() member +functions. Setting match_limit to a non-zero value will limit the +execution of pcre to keep it from doing bad things like blowing the stack or +taking an eternity to return a result. A value of 5000 is good enough to stop +stack blowup in a 2MB thread stack. Setting match_limit to zero disables +match limiting. Alternatively, you can call match_limit_recursion() +which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much PCRE +recurses. match_limit() limits the number of matches PCRE does; +match_limit_recursion() limits the depth of internal recursion, and +therefore the amount of stack that is used. +

+

+Normally, to pass one or more modifiers to a RE class, you declare +a RE_Options object, set the appropriate options, and pass this +object to a RE constructor. Example: +

+   RE_options opt;
+   opt.set_caseless(true);
+   if (RE("HELLO", opt).PartialMatch("hello world")) ...
+
+RE_options has two constructors. The default constructor takes no arguments and +creates a set of flags that are off by default. The optional parameter +option_flags is to facilitate transfer of legacy code from C programs. +This lets you do +
+   RE(pattern,
+     RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str);
+
+However, new code is better off doing +
+   RE(pattern,
+     RE_Options().set_caseless(true).set_multiline(true))
+       .PartialMatch(str);
+
+If you are going to pass one of the most used modifiers, there are some +convenience functions that return a RE_Options class with the +appropriate modifier already set: CASELESS(), UTF8(), +MULTILINE(), DOTALL(), and EXTENDED(). +

+

+If you need to set several options at once, and you don't want to go through +the pains of declaring a RE_Options object and setting several options, there +is a parallel method that give you such ability on the fly. You can concatenate +several set_xxxxx() member functions, since each of them returns a +reference to its class object. For example, to pass PCRE_CASELESS, +PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one statement, you may write: +

+   RE(" ^ xyz \\s+ .* blah$",
+     RE_Options()
+       .set_caseless(true)
+       .set_extended(true)
+       .set_multiline(true)).PartialMatch(sometext);
+
+
+

+
SCANNING TEXT INCREMENTALLY
+

+The "Consume" operation may be useful if you want to repeatedly +match regular expressions at the front of a string and skip over +them as they match. This requires use of the "StringPiece" type, +which represents a sub-range of a real string. Like RE, StringPiece +is defined in the pcrecpp namespace. +

+  Example: read lines of the form "var = value" from a string.
+     string contents = ...;                 // Fill string somehow
+     pcrecpp::StringPiece input(contents);  // Wrap in a StringPiece
+
+

+

+

+     string var;
+     int value;
+     pcrecpp::RE re("(\\w+) = (\\d+)\n");
+     while (re.Consume(&input, &var, &value)) {
+       ...;
+     }
+
+Each successful call to "Consume" will set "var/value", and also +advance "input" so it points past the matched text. +

+

+The "FindAndConsume" operation is similar to "Consume" but does not +anchor your match at the beginning of the string. For example, you +could extract all words from a string by repeatedly calling +

+  pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word)
+
+

+
PARSING HEX/OCTAL/C-RADIX NUMBERS
+

+By default, if you pass a pointer to a numeric value, the +corresponding text is interpreted as a base-10 number. You can +instead wrap the pointer with a call to one of the operators Hex(), +Octal(), or CRadix() to interpret the text in another base. The +CRadix operator interprets C-style "0" (base-8) and "0x" (base-16) +prefixes, but defaults to base-10. +

+  Example:
+    int a, b, c, d;
+    pcrecpp::RE re("(.*) (.*) (.*) (.*)");
+    re.FullMatch("100 40 0100 0x40",
+                 pcrecpp::Octal(&a), pcrecpp::Hex(&b),
+                 pcrecpp::CRadix(&c), pcrecpp::CRadix(&d));
+
+will leave 64 in a, b, c, and d. +

+
REPLACING PARTS OF STRINGS
+

+You can replace the first match of "pattern" in "str" with "rewrite". +Within "rewrite", backslash-escaped digits (\1 to \9) can be +used to insert text matching corresponding parenthesized group +from the pattern. \0 in "rewrite" refers to the entire matching +text. For example: +

+  string s = "yabba dabba doo";
+  pcrecpp::RE("b+").Replace("d", &s);
+
+will leave "s" containing "yada dabba doo". The result is true if the pattern +matches and a replacement occurs, false otherwise. +

+

+GlobalReplace is like Replace except that it replaces all +occurrences of the pattern in the string with the rewrite. Replacements are +not subject to re-matching. For example: +

+  string s = "yabba dabba doo";
+  pcrecpp::RE("b+").GlobalReplace("d", &s);
+
+will leave "s" containing "yada dada doo". It returns the number of +replacements made. +

+

+Extract is like Replace, except that if the pattern matches, +"rewrite" is copied into "out" (an additional argument) with substitutions. +The non-matching portions of "text" are ignored. Returns true iff a match +occurred and the extraction happened successfully; if no match occurs, the +string is left unaffected. +

+of calling the PCRE regular expression library from a C program. See the
+pcresample documentation for a short discussion ("man pcresample" if you have

+
+In Unix-like environments, compile this program thuswise:

+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE are installed on your system. You don't need -I and -L
+if PCRE is installed in the standard system libraries. Only some operating
+systems (e.g. Solaris) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must

SYNOPSIS

+

+pcregrep [options] [long options] [pattern] [path1 path2 ...]
+

+
DESCRIPTION

+

+pcregrep searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+pcrepattern(3)
+for a full description of syntax and semantics of the regular expressions
+that PCRE supports.
+

+

+Patterns, whether supplied on the command line or in a separate file, are given
+without delimiters. For example:
+
+  pcregrep Thursday /etc/motd
+

+If you attempt to use delimiters (for example, by surrounding a pattern with
+slashes, as is common in Perl scripts), they are interpreted as part of the
+pattern. Quotes can of course be used to delimit patterns on the command line
+because they are interpreted by the shell, and indeed they are required if a
+pattern contains white space or shell metacharacters.
+

+

+The first argument that follows any option settings is treated as the single
+pattern to be matched when neither -e nor -f is present.
+Conversely, when one or both of these options are used to specify patterns, all
+arguments are treated as path names. At least one of -e, -f, or an
+argument pattern must be provided.
+

+

+If no files are specified, pcregrep reads the standard input. The
+standard input can also be referenced by a name consisting of a single hyphen.
+For example:
+
+  pcregrep some-pattern /file1 - /file3
+

+By default, each line that matches a pattern is copied to the standard
+output, and if there is more than one file, the file name is output at the
+start of each line, followed by a colon. However, there are options that can
+change how pcregrep behaves. In particular, the -M option makes it
+possible to search for patterns that span line boundaries. What defines a line
+boundary is controlled by the -N (--newline) option.
+

+

+Patterns are limited to 8K or BUFSIZ characters, whichever is the greater.
+BUFSIZ is defined in <stdio.h>. When there is more than one pattern
+(specified by the use of -e and/or -f), each pattern is applied to
+each line in the order in which they are defined, except that all the -e
+patterns are tried before the -f patterns.
+

+

+By default, as soon as one pattern matches (or fails to match when -v is
+used), no further patterns are considered. However, if --colour (or
+--color) is used to colour the matching substrings, or if
+--only-matching, --file-offsets, or --line-offsets is used to
+output only the part of the line that matched (either shown literally, or as an
+offset), scanning resumes immediately following the match, so that further
+matches on the same line can be found. If there are multiple patterns, they are
+all tried on the remainder of the line, but patterns that follow the one that
+matched are not tried on the earlier part of the line.
+

+

+This is the same behaviour as GNU grep, but it does mean that the order in
+which multiple patterns are specified can affect the output when one of the
+above options is used.
+

+

+Patterns that can match an empty string are accepted, but empty string
+matches are never recognized. An example is the pattern "(super)?(man)?", in
+which all components are optional. This pattern finds all occurrences of both
+"super" and "man"; the output differs from matching with "super|man" when only
+the matching substrings are being shown.
+

+

+If the LC_ALL or LC_CTYPE environment variable is set,
+pcregrep uses the value to set a locale when calling the PCRE library.
+The --locale option can be used to override this.
+

+
SUPPORT FOR COMPRESSED FILES

+

+It is possible to compile pcregrep so that it uses libz or
+libbz2 to read files whose names end in .gz or .bz2,
+respectively. You can find out whether your binary has support for one or both
+of these file types by running it with the --help option. If the
+appropriate support is not present, files are treated as plain text. The
+standard input is always so treated.
+

+
OPTIONS

+

+The order in which some of the options appear can affect the output. For
+example, both the -h and -l options affect the printing of file
+names. Whichever comes later in the command line will be the one that takes
+effect.
+

+

+--
+This terminate the list of options. It is useful if the next item on the
+command line starts with a hyphen but is not an option. This allows for the
+processing of patterns and filenames that start with hyphens.
+

+

+-A number, --after-context=number
+Output number lines of context after each matching line. If filenames
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of number is expected to be relatively small. However, pcregrep
+guarantees to have up to 8K of following text available for context output.
+

+

+-B number, --before-context=number
+Output number lines of context before each matching line. If filenames
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of number is expected to be relatively small. However, pcregrep
+guarantees to have up to 8K of preceding text available for context output.
+

+

+-C number, --context=number
+Output number lines of context both before and after each matching line.
+This is equivalent to setting both -A and -B to the same value.
+

+

+-c, --count
+Do not output individual lines from the files that are being scanned; instead
+output the number of lines that would otherwise have been shown. If no lines
+are selected, the number zero is output. If several files are are being
+scanned, a count is output for each of them. However, if the
+--files-with-matches option is also used, only those files whose counts
+are greater than zero are listed. When -c is used, the -A,
+-B, and -C options are ignored.
+

+

+--colour, --color
+If this option is given without any data, it is equivalent to "--colour=auto".
+If data is required, it must be given in the same shell item, separated by an
+equals sign.
+

+

+--colour=value, --color=value
+This option specifies under what circumstances the parts of a line that matched
+a pattern should be coloured in the output. By default, the output is not
+coloured. The value (which is optional, see above) may be "never", "always", or
+"auto". In the latter case, colouring happens only if the standard output is
+connected to a terminal. More resources are used when colouring is enabled,
+because pcregrep has to search for all possible matches in a line, not
+just one, in order to colour them all.
+

+

+The colour that is used can be specified by setting the environment variable
+PCREGREP_COLOUR or PCREGREP_COLOR. The value of this variable should be a
+string of two numbers, separated by a semicolon. They are copied directly into
+the control string for setting colour on a terminal, so it is your
+responsibility to ensure that they make sense. If neither of the environment
+variables is set, the default is "1;31", which gives red.
+

+

+-D action, --devices=action
+If an input path is not a regular file or a directory, "action" specifies how
+it is to be processed. Valid values are "read" (the default) or "skip"
+(silently skip the path).
+

+

+-d action, --directories=action
+If an input path is a directory, "action" specifies how it is to be processed.
+Valid values are "read" (the default), "recurse" (equivalent to the -r
+option), or "skip" (silently skip the path). In the default case, directories
+are read as if they were ordinary files. In some operating systems the effect
+of reading a directory like this is an immediate end-of-file.
+

+

+-e pattern, --regex=pattern, --regexp=pattern
+Specify a pattern to be matched. This option can be used multiple times in
+order to specify several patterns. It can also be used as a way of specifying a
+single pattern that starts with a hyphen. When -e is used, no argument
+pattern is taken from the command line; all arguments are treated as file
+names. There is an overall maximum of 100 patterns. They are applied to each
+line in the order in which they are defined until one matches (or fails to
+match if -v is used). If -f is used with -e, the command line
+patterns are matched first, followed by the patterns from the file, independent
+of the order in which these options are specified. Note that multiple use of
+-e is not the same as a single pattern with alternatives. For example,
+X|Y finds the first character in a line that is X or Y, whereas if the two
+patterns are given separately, pcregrep finds X if it is present, even if
+it follows Y in the line. It finds Y only if there is no X in the line. This
+really matters only if you are using -o to show the part(s) of the line
+that matched.
+

+

+--exclude=pattern
+When pcregrep is searching the files in a directory as a consequence of
+the -r (recursive search) option, any regular files whose names match the
+pattern are excluded. Subdirectories are not excluded by this option; they are
+searched recursively, subject to the --exclude_dir and
+--include_dir options. The pattern is a PCRE regular expression, and is
+matched against the final component of the file name (not the entire path). If
+a file name matches both --include and --exclude, it is excluded.
+There is no short form for this option.
+

+

+--exclude_dir=pattern
+When pcregrep is searching the contents of a directory as a consequence
+of the -r (recursive search) option, any subdirectories whose names match
+the pattern are excluded. (Note that the \fP--exclude\fP option does not affect
+subdirectories.) The pattern is a PCRE regular expression, and is matched
+against the final component of the name (not the entire path). If a
+subdirectory name matches both --include_dir and --exclude_dir, it
+is excluded. There is no short form for this option.
+

+

+-F, --fixed-strings
+Interpret each pattern as a list of fixed strings, separated by newlines,
+instead of as a regular expression. The -w (match as a word) and -x
+(match whole line) options can be used with -F. They apply to each of the
+fixed strings. A line is selected if any of the fixed strings are found in it
+(subject to -w or -x, if present).
+

+

+-f filename, --file=filename
+Read a number of patterns from the file, one per line, and match them against
+each line of input. A data line is output if any of the patterns match it. The
+filename can be given as "-" to refer to the standard input. When -f is
+used, patterns specified on the command line using -e may also be
+present; they are tested before the file's patterns. However, no other pattern
+is taken from the command line; all arguments are treated as file names. There
+is an overall maximum of 100 patterns. Trailing white space is removed from
+each line, and blank lines are ignored. An empty file contains no patterns and
+therefore matches nothing. See also the comments about multiple patterns versus
+a single pattern with alternatives in the description of -e above.
+

+

+--file-offsets
+Instead of showing lines or parts of lines that match, show each match as an
+offset from the start of the file and a length, separated by a comma. In this
+mode, no context is shown. That is, the -A, -B, and -C
+options are ignored. If there is more than one match in a line, each of them is
+shown separately. This option is mutually exclusive with --line-offsets
+and --only-matching.
+

+

+-H, --with-filename
+Force the inclusion of the filename at the start of output lines when searching
+a single file. By default, the filename is not shown in this case. For matching
+lines, the filename is followed by a colon; for context lines, a hyphen
+separator is used. If a line number is also being output, it follows the file
+name.
+

+

+-h, --no-filename
+Suppress the output filenames when searching multiple files. By default,
+filenames are shown when multiple files are searched. For matching lines, the
+filename is followed by a colon; for context lines, a hyphen separator is used.
+If a line number is also being output, it follows the file name.
+

+

+--help
+Output a help message, giving brief details of the command options and file
+type support, and then exit.
+

+

+-i, --ignore-case
+Ignore upper/lower case distinctions during comparisons.
+

+

+--include=pattern
+When pcregrep is searching the files in a directory as a consequence of
+the -r (recursive search) option, only those regular files whose names
+match the pattern are included. Subdirectories are always included and searched
+recursively, subject to the \fP--include_dir\fP and --exclude_dir
+options. The pattern is a PCRE regular expression, and is matched against the
+final component of the file name (not the entire path). If a file name matches
+both --include and --exclude, it is excluded. There is no short
+form for this option.
+

+

+--include_dir=pattern
+When pcregrep is searching the contents of a directory as a consequence
+of the -r (recursive search) option, only those subdirectories whose
+names match the pattern are included. (Note that the --include option
+does not affect subdirectories.) The pattern is a PCRE regular expression, and
+is matched against the final component of the name (not the entire path). If a
+subdirectory name matches both --include_dir and --exclude_dir, it
+is excluded. There is no short form for this option.
+

+

+-L, --files-without-match
+Instead of outputting lines from the files, just output the names of the files
+that do not contain any lines that would have been output. Each file name is
+output once, on a separate line.
+

+

+-l, --files-with-matches
+Instead of outputting lines from the files, just output the names of the files
+containing lines that would have been output. Each file name is output
+once, on a separate line. Searching normally stops as soon as a matching line
+is found in a file. However, if the -c (count) option is also used,
+matching continues in order to obtain the correct count, and those files that
+have at least one match are listed along with their counts. Using this option
+with -c is a way of suppressing the listing of files with no matches.
+

+

+--label=name
+This option supplies a name to be used for the standard input when file names
+are being output. If not supplied, "(standard input)" is used. There is no
+short form for this option.
+

+

+--line-offsets
+Instead of showing lines or parts of lines that match, show each match as a
+line number, the offset from the start of the line, and a length. The line
+number is terminated by a colon (as usual; see the -n option), and the
+offset and length are separated by a comma. In this mode, no context is shown.
+That is, the -A, -B, and -C options are ignored. If there is
+more than one match in a line, each of them is shown separately. This option is
+mutually exclusive with --file-offsets and --only-matching.
+

+

+--locale=locale-name
+This option specifies a locale to be used for pattern matching. It overrides
+the value in the LC_ALL or LC_CTYPE environment variables. If no
+locale is specified, the PCRE library's default (usually the "C" locale) is
+used. There is no short form for this option.
+

+

+-M, --multiline
+Allow patterns to match more than one line. When this option is given, patterns
+may usefully contain literal newline characters and internal occurrences of ^
+and $ characters. The output for any one match may consist of more than one
+line. When this option is set, the PCRE library is called in "multiline" mode.
+There is a limit to the number of lines that can be matched, imposed by the way
+that pcregrep buffers the input file as it scans it. However,
+pcregrep ensures that at least 8K characters or the rest of the document
+(whichever is the shorter) are available for forward matching, and similarly
+the previous 8K characters (or all the previous characters, if fewer than 8K)
+are guaranteed to be available for lookbehind assertions.
+

+

+-N newline-type, --newline=newline-type
+The PCRE library supports five different conventions for indicating
+the ends of lines. They are the single-character sequences CR (carriage return)
+and LF (linefeed), the two-character sequence CRLF, an "anycrlf" convention,
+which recognizes any of the preceding three types, and an "any" convention, in
+which any Unicode line ending sequence is assumed to end a line. The Unicode
+sequences are the three just mentioned, plus VT (vertical tab, U+000B), FF
+(formfeed, U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and
+PS (paragraph separator, U+2029).
+

+

+When the PCRE library is built, a default line-ending sequence is specified.
+This is normally the standard sequence for the operating system. Unless
+otherwise specified by this option, pcregrep uses the library's default.
+The possible values for this option are CR, LF, CRLF, ANYCRLF, or ANY. This
+makes it possible to use pcregrep on files that have come from other
+environments without having to modify their line endings. If the data that is
+being scanned does not agree with the convention set by this option,
+pcregrep may behave in strange ways.
+

+

+-n, --line-number
+Precede each output line by its line number in the file, followed by a colon
+for matching lines or a hyphen for context lines. If the filename is also being
+output, it precedes the line number. This option is forced if
+--line-offsets is used.
+

+

+-o, --only-matching
+Show only the part of the line that matched a pattern. In this mode, no
+context is shown. That is, the -A, -B, and -C options are
+ignored. If there is more than one match in a line, each of them is shown
+separately. If -o is combined with -v (invert the sense of the
+match to find non-matching lines), no output is generated, but the return code
+is set appropriately. This option is mutually exclusive with
+--file-offsets and --line-offsets.
+

+

+-q, --quiet
+Work quietly, that is, display nothing except error messages. The exit
+status indicates whether or not any matches were found.
+

+

+-r, --recursive
+If any given path is a directory, recursively scan the files it contains,
+taking note of any --include and --exclude settings. By default, a
+directory is read as a normal file; in some operating systems this gives an
+immediate end-of-file. This option is a shorthand for setting the -d
+option to "recurse".
+

+

+-s, --no-messages
+Suppress error messages about non-existent or unreadable files. Such files are
+quietly skipped. However, the return code is still 2, even if matches were
+found in other files.
+

+

+-u, --utf-8
+Operate in UTF-8 mode. This option is available only if PCRE has been compiled
+with UTF-8 support. Both patterns and subject lines must be valid strings of
+UTF-8 characters.
+

+

+-V, --version
+Write the version numbers of pcregrep and the PCRE library that is being
+used to the standard error stream.
+

+

+-v, --invert-match
+Invert the sense of the match, so that lines which do not match any of
+the patterns are the ones that are found.
+

+

+-w, --word-regex, --word-regexp
+Force the patterns to match only whole words. This is equivalent to having \b
+at the start and end of the pattern.
+

+

+-x, --line-regex, --line-regexp
+Force the patterns to be anchored (each must start matching at the beginning of
+a line) and in addition, require them to match entire lines. This is
+equivalent to having ^ and $ characters at the start and end of each
+alternative branch in every pattern.
+

+
ENVIRONMENT VARIABLES

+

+The environment variables LC_ALL and LC_CTYPE are examined, in that
+order, for a locale. The first one that is set is used. This can be overridden
+by the --locale option. If no locale is set, the PCRE library's default
+(usually the "C" locale) is used.
+

+
NEWLINES

+

+The -N (--newline) option allows pcregrep to scan files with
+different newline conventions from the default. However, the setting of this
+option does not affect the way in which pcregrep writes information to
+the standard error and output streams. It uses the string "\n" in C
+printf() calls to indicate newlines, relying on the C I/O library to
+convert this to an appropriate sequence if the output is sent to a file.
+

+
OPTIONS COMPATIBILITY

+

+The majority of short and long forms of pcregrep's options are the same
+as in the GNU grep program. Any long option of the form
+--xxx-regexp (GNU terminology) is also available as --xxx-regex
+(PCRE terminology). However, the --locale, -M, --multiline,
+-u, and --utf-8 options are specific to pcregrep. If both the
+-c and -l options are given, GNU grep lists only file names,
+without counts, but pcregrep gives the counts.
+

+
OPTIONS WITH DATA

+

+There are four different ways in which an option with data can be specified.
+If a short form option is used, the data may follow immediately, or in the next
+command line item. For example:
+
+  -f/some/file
+  -f /some/file
+

+If a long form option is used, the data may appear in the same command line
+item, separated by an equals character, or (with one exception) it may appear
+in the next command line item. For example:
+
+  --file=/some/file
+  --file /some/file
+

+Note, however, that if you want to supply a file name beginning with ~ as data
+in a shell command, and have the shell expand ~ to a home directory, you must
+separate the file name from the option, because the shell does not treat ~
+specially unless it is at the start of an item.
+

+

+The exception to the above is the --colour (or --color) option,
+for which the data is optional. If this option does have data, it must be given
+in the first form, using an equals character. Otherwise it will be assumed that
+it has no data.
+

+
MATCHING ERRORS

+

+It is possible to supply a regular expression that takes a very long time to
+fail to match certain lines. Such patterns normally involve nested indefinite
+repeats, for example: (a+)*\d when matched against a line of a's with no final
+digit. The PCRE matching function has a resource limit that causes it to abort
+in these circumstances. If this happens, pcregrep outputs an error
+message and the line that caused the problem to the standard error stream. If
+there are more than 20 such errors, pcregrep gives up.
+

+
DIAGNOSTICS

+

+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors and non-existent or inacessible files (even if matches were
+found in other files) or too many matching errors. Using the -s option to
+suppress error messages about inaccessble files does not affect the return
+code.

PCRE MATCHING ALGORITHMS

+

+This document describes the two different algorithms that are available in PCRE
+for matching a compiled regular expression against a given subject string. The
+"standard" algorithm is the one provided by the pcre_exec() function.
+This works in the same was as Perl's matching function, and provides a
+Perl-compatible matching operation.
+

+

+An alternative algorithm is provided by the pcre_dfa_exec() function;
+this operates in a different way, and is not Perl-compatible. It has advantages
+and disadvantages compared with the standard algorithm, and these are described
+below.
+

+

+When there is only one possible way in which a given subject string can match a
+pattern, the two algorithms give the same answer. A difference arises, however,
+when there are multiple possibilities. For example, if the pattern
+
+  ^<.*>
+

+is matched against the string
+
+  <something> <something else> <something further>
+

+there are three possible answers. The standard algorithm finds only one of
+them, whereas the alternative algorithm finds all three.
+

+
REGULAR EXPRESSIONS AS TREES

+

+The set of strings that are matched by a regular expression can be represented
+as a tree structure. An unlimited repetition in the pattern makes the tree of
+infinite size, but it is still a tree. Matching the pattern to a given subject
+string (from a given starting point) can be thought of as a search of the tree.
+There are two ways to search a tree: depth-first and breadth-first, and these
+correspond to the two matching algorithms provided by PCRE.
+

+
THE STANDARD MATCHING ALGORITHM

+

+In the terminology of Jeffrey Friedl's book "Mastering Regular
+Expressions", the standard algorithm is an "NFA algorithm". It conducts a
+depth-first search of the pattern tree. That is, it proceeds along a single
+path through the tree, checking that the subject matches what is required. When
+there is a mismatch, the algorithm tries any alternatives at the current point,
+and if they all fail, it backs up to the previous branch point in the tree, and
+tries the next alternative branch at that level. This often involves backing up
+(moving to the left) in the subject string as well. The order in which
+repetition branches are tried is controlled by the greedy or ungreedy nature of
+the quantifier.
+

+

+If a leaf node is reached, a matching string has been found, and at that point
+the algorithm stops. Thus, if there is more than one possible match, this
+algorithm returns the first one that it finds. Whether this is the shortest,
+the longest, or some intermediate length depends on the way the greedy and
+ungreedy repetition quantifiers are specified in the pattern.
+

+

+Because it ends up with a single path through the tree, it is relatively
+straightforward for this algorithm to keep track of the substrings that are
+matched by portions of the pattern in parentheses. This provides support for
+capturing parentheses and back references.
+

+
THE ALTERNATIVE MATCHING ALGORITHM

+

+This algorithm conducts a breadth-first search of the tree. Starting from the
+first matching point in the subject, it scans the subject string from left to
+right, once, character by character, and as it does this, it remembers all the
+paths through the tree that represent valid matches. In Friedl's terminology,
+this is a kind of "DFA algorithm", though it is not implemented as a
+traditional finite state machine (it keeps multiple states active
+simultaneously).
+

+

+Although the general principle of this matching algorithm is that it scans the
+subject string only once, without backtracking, there is one exception: when a
+lookaround assertion is encountered, the characters following or preceding the
+current point have to be independently inspected.
+

+

+The scan continues until either the end of the subject is reached, or there are
+no more unterminated paths. At this point, terminated paths represent the
+different matching possibilities (if there are none, the match has failed).
+Thus, if there is more than one possible match, this algorithm finds all of
+them, and in particular, it finds the longest. There is an option to stop the
+algorithm after the first match (which is necessarily the shortest) is found.
+

+

+Note that all the matches that are found start at the same point in the
+subject. If the pattern
+
+  cat(er(pillar)?)
+

+is matched against the string "the caterpillar catchment", the result will be
+the three strings "cat", "cater", and "caterpillar" that start at the fourth
+character of the subject. The algorithm does not automatically move on to find
+matches that start at later positions.
+

+

+There are a number of features of PCRE regular expressions that are not
+supported by the alternative matching algorithm. They are as follows:
+

+

+1. Because the algorithm finds all possible matches, the greedy or ungreedy
+nature of repetition quantifiers is not relevant. Greedy and ungreedy
+quantifiers are treated in exactly the same way. However, possessive
+quantifiers can make a difference when what follows could also match what is
+quantified, for example in a pattern like this:
+
+  ^a++\w!
+

+This pattern matches "aaab!" but not "aaa!", which would be matched by a
+non-possessive quantifier. Similarly, if an atomic group is present, it is
+matched as if it were a standalone pattern at the current point, and the
+longest match is then "locked in" for the rest of the overall pattern.
+

+

+2. When dealing with multiple paths through the tree simultaneously, it is not
+straightforward to keep track of captured substrings for the different matching
+possibilities, and PCRE's implementation of this algorithm does not attempt to
+do this. This means that no captured substrings are available.
+

+

+3. Because no substrings are captured, back references within the pattern are
+not supported, and cause errors if encountered.
+

+

+4. For the same reason, conditional expressions that use a backreference as the
+condition or test for a specific group recursion are not supported.
+

+

+5. Because many paths through the tree may be active, the \K escape sequence,
+which resets the start of the match when encountered (but may be on some paths
+and not on others), is not supported. It causes an error if encountered.
+

+

+6. Callouts are supported, but the value of the capture_top field is
+always 1, and the value of the capture_last field is always -1.
+

+

+7. The \C escape sequence, which (in the standard algorithm) matches a single
+byte, even in UTF-8 mode, is not supported because the alternative algorithm
+moves through the subject string one character at a time, for all active paths
+through the tree.
+

+

+8. Except for (*FAIL), the backtracking control verbs such as (*PRUNE) are not
+supported. (*FAIL) is supported, and behaves like a failing negative assertion.
+

+
ADVANTAGES OF THE ALTERNATIVE ALGORITHM

+

+Using the alternative matching algorithm provides the following advantages:
+

+

+1. All possible matches (at a single point in the subject) are automatically
+found, and in particular, the longest match is found. To find more than one
+match using the standard algorithm, you have to do kludgy things with
+callouts.
+

+

+2. Because the alternative algorithm scans the subject string just once, and
+never needs to backtrack, it is possible to pass very long subject strings to
+the matching function in several pieces, checking for partial matching each
+time. The
+pcrepartial
+documentation gives details of partial matching.
+

+
DISADVANTAGES OF THE ALTERNATIVE ALGORITHM

+

+The alternative algorithm suffers from a number of disadvantages:
+

+

+1. It is substantially slower than the standard algorithm. This is partly
+because it has to search for all possible matches, but is also because it is
+less susceptible to optimization.
+

+

+2. Capturing parentheses and back references are not supported.
+

+

+3. Although atomic groups are supported, their use does not provide the
+performance advantage that it does for the standard algorithm.

+
PARTIAL MATCHING IN PCRE

+

+In normal use of PCRE, if the subject string that is passed to
+pcre_exec() or pcre_dfa_exec() matches as far as it goes, but is
+too short to match the entire pattern, PCRE_ERROR_NOMATCH is returned. There
+are circumstances where it might be helpful to distinguish this case from other
+cases in which there is no match.
+

+

+Consider, for example, an application where a human is required to type in data
+for a field with specific formatting requirements. An example might be a date
+in the form ddmmmyy, defined by this pattern:
+
+  ^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$
+

+If the application sees the user's keystrokes one by one, and can check that
+what has been typed so far is potentially valid, it is able to raise an error
+as soon as a mistake is made, by beeping and not reflecting the character that
+has been typed, for example. This immediate feedback is likely to be a better
+user interface than a check that is delayed until the entire string has been
+entered. Partial matching can also sometimes be useful when the subject string
+is very long and is not all available at once.
+

+

+PCRE supports partial matching by means of the PCRE_PARTIAL_SOFT and
+PCRE_PARTIAL_HARD options, which can be set when calling pcre_exec() or
+pcre_dfa_exec(). For backwards compatibility, PCRE_PARTIAL is a synonym
+for PCRE_PARTIAL_SOFT. The essential difference between the two options is
+whether or not a partial match is preferred to an alternative complete match,
+though the details differ between the two matching functions. If both options
+are set, PCRE_PARTIAL_HARD takes precedence.
+

+

+Setting a partial matching option disables two of PCRE's optimizations. PCRE
+remembers the last literal byte in a pattern, and abandons matching immediately
+if such a byte is not present in the subject string. This optimization cannot
+be used for a subject string that might match only partially. If the pattern
+was studied, PCRE knows the minimum length of a matching string, and does not
+bother to run the matching function on shorter strings. This optimization is
+also disabled for partial matching.
+

+
PARTIAL MATCHING USING pcre_exec()

+

+A partial match occurs during a call to pcre_exec() whenever the end of
+the subject string is reached successfully, but matching cannot continue
+because more characters are needed. However, at least one character must have
+been matched. (In other words, a partial match can never be an empty string.)
+

+

+If PCRE_PARTIAL_SOFT is set, the partial match is remembered, but matching
+continues as normal, and other alternatives in the pattern are tried. If no
+complete match can be found, pcre_exec() returns PCRE_ERROR_PARTIAL
+instead of PCRE_ERROR_NOMATCH. If there are at least two slots in the offsets
+vector, the first of them is set to the offset of the earliest character that
+was inspected when the partial match was found. For convenience, the second
+offset points to the end of the string so that a substring can easily be
+identified.
+

+

+For the majority of patterns, the first offset identifies the start of the
+partially matched string. However, for patterns that contain lookbehind
+assertions, or \K, or begin with \b or \B, earlier characters have been
+inspected while carrying out the match. For example:
+
+  /(?<=abc)123/
+

+This pattern matches "123", but only if it is preceded by "abc". If the subject
+string is "xyzabc12", the offsets after a partial match are for the substring
+"abc12", because all these characters are needed if another match is tried
+with extra characters added.
+

+

+If there is more than one partial match, the first one that was found provides
+the data that is returned. Consider this pattern:
+
+  /123\w+X|dogY/
+

+If this is matched against the subject string "abc123dog", both
+alternatives fail to match, but the end of the subject is reached during
+matching, so PCRE_ERROR_PARTIAL is returned instead of PCRE_ERROR_NOMATCH. The
+offsets are set to 3 and 9, identifying "123dog" as the first partial match
+that was found. (In this example, there are two partial matches, because "dog"
+on its own partially matches the second alternative.)
+

+

+If PCRE_PARTIAL_HARD is set for pcre_exec(), it returns
+PCRE_ERROR_PARTIAL as soon as a partial match is found, without continuing to
+search for possible complete matches. The difference between the two options
+can be illustrated by a pattern such as:
+
+  /dog(sbody)?/
+

+This matches either "dog" or "dogsbody", greedily (that is, it prefers the
+longer string if possible). If it is matched against the string "dog" with
+PCRE_PARTIAL_SOFT, it yields a complete match for "dog". However, if
+PCRE_PARTIAL_HARD is set, the result is PCRE_ERROR_PARTIAL. On the other hand,
+if the pattern is made ungreedy the result is different:
+
+  /dog(sbody)??/
+

+In this case the result is always a complete match because pcre_exec()
+finds that first, and it never continues after finding a match. It might be
+easier to follow this explanation by thinking of the two patterns like this:
+
+  /dog(sbody)?/    is the same as  /dogsbody|dog/
+  /dog(sbody)??/   is the same as  /dog|dogsbody/
+

+The second pattern will never match "dogsbody" when pcre_exec() is
+used, because it will always find the shorter match first.
+

+
PARTIAL MATCHING USING pcre_dfa_exec()

+

+The pcre_dfa_exec() function moves along the subject string character by
+character, without backtracking, searching for all possible matches
+simultaneously. If the end of the subject is reached before the end of the
+pattern, there is the possibility of a partial match, again provided that at
+least one character has matched.
+

+

+When PCRE_PARTIAL_SOFT is set, PCRE_ERROR_PARTIAL is returned only if there
+have been no complete matches. Otherwise, the complete matches are returned.
+However, if PCRE_PARTIAL_HARD is set, a partial match takes precedence over any
+complete matches. The portion of the string that was inspected when the longest
+partial match was found is set as the first matching string, provided there are
+at least two slots in the offsets vector.
+

+

+Because pcre_dfa_exec() always searches for all possible matches, and
+there is no difference between greedy and ungreedy repetition, its behaviour is
+different from pcre_exec when PCRE_PARTIAL_HARD is set. Consider the
+string "dog" matched against the ungreedy pattern shown above:
+
+  /dog(sbody)??/
+

+Whereas pcre_exec() stops as soon as it finds the complete match for
+"dog", pcre_dfa_exec() also finds the partial match for "dogsbody", and
+so returns that when PCRE_PARTIAL_HARD is set.
+

+
PARTIAL MATCHING AND WORD BOUNDARIES

+

+If a pattern ends with one of sequences \b or \B, which test for word
+boundaries, partial matching with PCRE_PARTIAL_SOFT can give counter-intuitive
+results. Consider this pattern:
+
+  /\bcat\b/
+

+This matches "cat", provided there is a word boundary at either end. If the
+subject string is "the cat", the comparison of the final "t" with a following
+character cannot take place, so a partial match is found. However,
+pcre_exec() carries on with normal matching, which matches \b at the end
+of the subject when the last character is a letter, thus finding a complete
+match. The result, therefore, is not PCRE_ERROR_PARTIAL. The same thing
+happens with pcre_dfa_exec(), because it also finds the complete match.
+

+

+Using PCRE_PARTIAL_HARD in this case does yield PCRE_ERROR_PARTIAL, because
+then the partial match takes precedence.
+

+
FORMERLY RESTRICTED PATTERNS

+

+For releases of PCRE prior to 8.00, because of the way certain internal
+optimizations were implemented in the pcre_exec() function, the
+PCRE_PARTIAL option (predecessor of PCRE_PARTIAL_SOFT) could not be used with
+all patterns. From release 8.00 onwards, the restrictions no longer apply, and
+partial matching with pcre_exec() can be requested for any pattern.
+

+

+Items that were formerly restricted were repeated single characters and
+repeated metasequences. If PCRE_PARTIAL was set for a pattern that did not
+conform to the restrictions, pcre_exec() returned the error code
+PCRE_ERROR_BADPARTIAL (-13). This error code is no longer in use. The
+PCRE_INFO_OKPARTIAL call to pcre_fullinfo() to find out if a compiled
+pattern can be used for partial matching now always returns 1.
+

+
EXAMPLE OF PARTIAL MATCHING USING PCRETEST

+

+If the escape sequence \P is present in a pcretest data line, the
+PCRE_PARTIAL_SOFT option is used for the match. Here is a run of pcretest
+that uses the date example quoted above:
+
+    re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+  data> 25jun04\P
+   0: 25jun04
+   1: jun
+  data> 25dec3\P
+  Partial match: 23dec3
+  data> 3ju\P
+  Partial match: 3ju
+  data> 3juj\P
+  No match
+  data> j\P
+  No match
+

+The first data string is matched completely, so pcretest shows the
+matched substrings. The remaining four strings do not match the complete
+pattern, but the first two are partial matches. Similar output is obtained
+when pcre_dfa_exec() is used.
+

+

+If the escape sequence \P is present more than once in a pcretest data
+line, the PCRE_PARTIAL_HARD option is set for the match.
+

+
MULTI-SEGMENT MATCHING WITH pcre_dfa_exec()

+

+When a partial match has been found using pcre_dfa_exec(), it is possible
+to continue the match by providing additional subject data and calling
+pcre_dfa_exec() again with the same compiled regular expression, this
+time setting the PCRE_DFA_RESTART option. You must pass the same working
+space as before, because this is where details of the previous partial match
+are stored. Here is an example using pcretest, using the \R escape
+sequence to set the PCRE_DFA_RESTART option (\D specifies the use of
+pcre_dfa_exec()):
+
+    re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+  data> 23ja\P\D
+  Partial match: 23ja
+  data> n05\R\D
+   0: n05
+

+The first call has "23ja" as the subject, and requests partial matching; the
+second call has "n05" as the subject for the continued (restarted) match.
+Notice that when the match is complete, only the last part is shown; PCRE does
+not retain the previously partially-matched string. It is up to the calling
+program to do that if it needs to.
+

+

+You can set the PCRE_PARTIAL_SOFT or PCRE_PARTIAL_HARD options with
+PCRE_DFA_RESTART to continue partial matching over multiple segments. This
+facility can be used to pass very long subject strings to
+pcre_dfa_exec().
+

+
MULTI-SEGMENT MATCHING WITH pcre_exec()

+

+From release 8.00, pcre_exec() can also be used to do multi-segment
+matching. Unlike pcre_dfa_exec(), it is not possible to restart the
+previous match with a new segment of data. Instead, new data must be added to
+the previous subject string, and the entire match re-run, starting from the
+point where the partial match occurred. Earlier data can be discarded.
+Consider an unanchored pattern that matches dates:
+
+    re> /\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d/
+  data> The date is 23ja\P
+  Partial match: 23ja
+

+At this stage, an application could discard the text preceding "23ja", add on
+text from the next segment, and call pcre_exec() again. Unlike
+pcre_dfa_exec(), the entire matching string must always be available, and
+the complete matching process occurs for each call, so more memory and more
+processing time is needed.
+

+

+Note: If the pattern contains lookbehind assertions, or \K, or starts
+with \b or \B, the string that is returned for a partial match will include
+characters that precede the partially matched string itself, because these must
+be retained when adding on more characters for a subsequent matching attempt.
+

+
ISSUES WITH MULTI-SEGMENT MATCHING

+

+Certain types of pattern may give problems with multi-segment matching,
+whichever matching function is used.
+

+

+1. If the pattern contains tests for the beginning or end of a line, you need
+to pass the PCRE_NOTBOL or PCRE_NOTEOL options, as appropriate, when the
+subject string for any call does not contain the beginning or end of a line.
+

+

+2. Lookbehind assertions at the start of a pattern are catered for in the
+offsets that are returned for a partial match. However, in theory, a lookbehind
+assertion later in the pattern could require even earlier characters to be
+inspected, and it might not have been reached when a partial match occurs. This
+is probably an extremely unlikely case; you could guard against it to a certain
+extent by always including extra characters at the start.
+

+

+3. Matching a subject string that is split into multiple segments may not
+always produce exactly the same result as matching over one single long string,
+especially when PCRE_PARTIAL_SOFT is used. The section "Partial Matching and
+Word Boundaries" above describes an issue that arises if the pattern ends with
+\b or \B. Another kind of difference may occur when there are multiple
+matching possibilities, because a partial match result is given only when there
+are no completed matches. This means that as soon as the shortest match has
+been found, continuation to a new subject segment is no longer possible.
+Consider again this pcretest example:
+
+    re> /dog(sbody)?/
+  data> dogsb\P
+   0: dog
+  data> do\P\D
+  Partial match: do
+  data> gsb\R\P\D
+   0: g
+  data> dogsbody\D
+   0: dogsbody
+   1: dog
+

+The first data line passes the string "dogsb" to pcre_exec(), setting the
+PCRE_PARTIAL_SOFT option. Although the string is a partial match for
+"dogsbody", the result is not PCRE_ERROR_PARTIAL, because the shorter string
+"dog" is a complete match. Similarly, when the subject is presented to
+pcre_dfa_exec() in several parts ("do" and "gsb" being the first two) the
+match stops when "dog" has been found, and it is not possible to continue. On
+the other hand, if "dogsbody" is presented as a single string,
+pcre_dfa_exec() finds both matches.
+

+

+Because of these problems, it is probably best to use PCRE_PARTIAL_HARD when
+matching multi-segment data. The example above then behaves differently:
+
+    re> /dog(sbody)?/
+  data> dogsb\P\P
+  Partial match: dogsb
+  data> do\P\D
+  Partial match: do
+  data> gsb\R\P\P\D
+  Partial match: gsb
+
+

+

+

+4. Patterns that contain alternatives at the top level which do not all
+start with the same pattern item may not work as expected when
+PCRE_DFA_RESTART is used with pcre_dfa_exec(). For example, consider this
+pattern:
+
+  1234|3789
+

+If the first part of the subject is "ABC123", a partial match of the first
+alternative is found at offset 3. There is no partial match for the second
+alternative, because such a match does not start at the same point in the
+subject string. Attempting to continue with the string "7890" does not yield a
+match because only those alternatives that match at one point in the subject
+are remembered. The problem arises because the start of the second alternative
+matches within the first alternative. There is no problem with anchored
+patterns or patterns such as:
+
+  1234|ABCD
+

+where no string can be a partial match for both alternatives. This is not a
+problem if pcre_exec() is used, because the entire match has to be rerun
+each time:
+
+    re> /1234|3789/
+  data> ABC123\P
+  Partial match: 123
+  data> 1237890
+   0: 3789
+

+Of course, instead of using PCRE_DFA_PARTIAL, the same technique of re-running
+the entire match can also be used with pcre_dfa_exec(). Another
+possibility is to work with two buffers. If a partial match at offset n
+in the first buffer is followed by "no match" when PCRE_DFA_RESTART is used on
+the second buffer, you can then try a new match starting at offset n+1 in
+the first buffer.

PCRE REGULAR EXPRESSION DETAILS

+

+The syntax and semantics of the regular expressions that are supported by PCRE
+are described in detail below. There is a quick-reference syntax summary in the
+pcresyntax
+page. PCRE tries to match Perl syntax and semantics as closely as it can. PCRE
+also supports some alternative regular expression syntax (which does not
+conflict with the Perl syntax) in order to provide some compatibility with
+regular expressions in Python, .NET, and Oniguruma.
+

+

+Perl's regular expressions are described in its own documentation, and
+regular expressions in general are covered in a number of books, some of which
+have copious examples. Jeffrey Friedl's "Mastering Regular Expressions",
+published by O'Reilly, covers regular expressions in great detail. This
+description of PCRE's regular expressions is intended as reference material.
+

+

+The original operation of PCRE was on strings of one-byte characters. However,
+there is now also support for UTF-8 character strings. To use this,
+PCRE must be built to include UTF-8 support, and you must call
+pcre_compile() or pcre_compile2() with the PCRE_UTF8 option. There
+is also a special sequence that can be given at the start of a pattern:
+
+  (*UTF8)
+

+Starting a pattern with this sequence is equivalent to setting the PCRE_UTF8
+option. This feature is not Perl-compatible. How setting UTF-8 mode affects
+pattern matching is mentioned in several places below. There is also a summary
+of UTF-8 features in the
+section on UTF-8 support
+in the main
+pcre
+page.
+

+

+The remainder of this document discusses the patterns that are supported by
+PCRE when its main matching function, pcre_exec(), is used.
+From release 6.0, PCRE offers a second matching function,
+pcre_dfa_exec(), which matches using a different algorithm that is not
+Perl-compatible. Some of the features discussed below are not available when
+pcre_dfa_exec() is used. The advantages and disadvantages of the
+alternative function, and how it differs from the normal function, are
+discussed in the
+pcrematching
+page.
+

+
NEWLINE CONVENTIONS

+

+PCRE supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The
+pcreapi
+page has
+further discussion
+about newlines, and shows how to set the newline convention in the
+options arguments for the compiling and matching functions.
+

+

+It is also possible to specify a newline convention by starting a pattern
+string with one of the following five sequences:
+
+  (*CR)        carriage return
+  (*LF)        linefeed
+  (*CRLF)      carriage return, followed by linefeed
+  (*ANYCRLF)   any of the three above
+  (*ANY)       all Unicode newline sequences
+

+These override the default and the options given to pcre_compile() or
+pcre_compile2(). For example, on a Unix system where LF is the default
+newline sequence, the pattern
+
+  (*CR)a.b
+

+changes the convention to CR. That pattern matches "a\nb" because LF is no
+longer a newline. Note that these special settings, which are not
+Perl-compatible, are recognized only at the very start of a pattern, and that
+they must be in upper case. If more than one of them is present, the last one
+is used.
+

+

+The newline convention does not affect what the \R escape sequence matches. By
+default, this is any Unicode newline sequence, for Perl compatibility. However,
+this can be changed; see the description of \R in the section entitled
+"Newline sequences"
+below. A change of \R setting can be combined with a change of newline
+convention.
+

+
CHARACTERS AND METACHARACTERS

+

+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+
+  The quick brown fox
+

+matches a portion of a subject string that is identical to itself. When
+caseless matching is specified (the PCRE_CASELESS option), letters are matched
+independently of case. In UTF-8 mode, PCRE always understands the concept of
+case for characters whose values are less than 128, so caseless matching is
+always possible. For characters with higher values, the concept of case is
+supported if PCRE is compiled with Unicode property support, but not otherwise.
+If you want to use caseless matching for characters 128 and above, you must
+ensure that PCRE is compiled with Unicode property support as well as with
+UTF-8 support.
+

+

+The power of regular expressions comes from the ability to include alternatives
+and repetitions in the pattern. These are encoded in the pattern by the use of
+metacharacters, which do not stand for themselves but instead are
+interpreted in some special way.
+

+

+There are two different sets of metacharacters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized within square brackets. Outside square brackets, the metacharacters
+are as follows:
+
+  \      general escape character with several uses
+  ^      assert start of string (or line, in multiline mode)
+  $      assert end of string (or line, in multiline mode)
+  .      match any character except newline (by default)
+  [      start character class definition
+  |      start of alternative branch
+  (      start subpattern
+  )      end subpattern
+  ?      extends the meaning of (
+         also 0 or 1 quantifier
+         also quantifier minimizer
+  *      0 or more quantifier
+  +      1 or more quantifier
+         also "possessive quantifier"
+  {      start min/max quantifier
+

+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only metacharacters are:
+
+  \      general escape character
+  ^      negate the class, but only if the first character
+  -      indicates character range
+  [      POSIX character class (only if followed by POSIX syntax)
+  ]      terminates the character class
+

+The following sections describe the use of each of the metacharacters.
+

+
BACKSLASH

+

+The backslash character has several uses. Firstly, if it is followed by a
+non-alphanumeric character, it takes away any special meaning that character
+may have. This use of backslash as an escape character applies both inside and
+outside character classes.
+

+

+For example, if you want to match a * character, you write \* in the pattern.
+This escaping action applies whether or not the following character would
+otherwise be interpreted as a metacharacter, so it is always safe to precede a
+non-alphanumeric with backslash to specify that it stands for itself. In
+particular, if you want to match a backslash, you write \\.
+

+

+If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the
+pattern (other than in a character class) and characters between a # outside
+a character class and the next newline are ignored. An escaping backslash can
+be used to include a whitespace or # character as part of the pattern.
+

+

+If you want to remove the special meaning from a sequence of characters, you
+can do so by putting them between \Q and \E. This is different from Perl in
+that $ and @ are handled as literals in \Q...\E sequences in PCRE, whereas in
+Perl, $ and @ cause variable interpolation. Note the following examples:
+
+  Pattern            PCRE matches   Perl matches
+
+  \Qabc$xyz\E        abc$xyz        abc followed by the contents of $xyz
+  \Qabc\$xyz\E       abc\$xyz       abc\$xyz
+  \Qabc\E\$\Qxyz\E   abc$xyz        abc$xyz
+

+The \Q...\E sequence is recognized both inside and outside character classes.
+

+

+Non-printing characters
+

+

+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters, apart from the binary zero that terminates a pattern,
+but when a pattern is being prepared by text editing, it is often easier to use
+one of the following escape sequences than the binary character it represents:
+
+  \a        alarm, that is, the BEL character (hex 07)
+  \cx       "control-x", where x is any character
+  \e        escape (hex 1B)
+  \f        formfeed (hex 0C)
+  \n        linefeed (hex 0A)
+  \r        carriage return (hex 0D)
+  \t        tab (hex 09)
+  \ddd      character with octal code ddd, or backreference
+  \xhh      character with hex code hh
+  \x{hhh..} character with hex code hhh..
+

+The precise effect of \cx is as follows: if x is a lower case letter, it
+is converted to upper case. Then bit 6 of the character (hex 40) is inverted.
+Thus \cz becomes hex 1A, but \c{ becomes hex 3B, while \c; becomes hex
+7B.
+

+

+After \x, from zero to two hexadecimal digits are read (letters can be in
+upper or lower case). Any number of hexadecimal digits may appear between \x{
+and }, but the value of the character code must be less than 256 in non-UTF-8
+mode, and less than 2**31 in UTF-8 mode. That is, the maximum value in
+hexadecimal is 7FFFFFFF. Note that this is bigger than the largest Unicode code
+point, which is 10FFFF.
+

+

+If characters other than hexadecimal digits appear between \x{ and }, or if
+there is no terminating }, this form of escape is not recognized. Instead, the
+initial \x will be interpreted as a basic hexadecimal escape, with no
+following digits, giving a character whose value is zero.
+

+

+Characters whose value is less than 256 can be defined by either of the two
+syntaxes for \x. There is no difference in the way they are handled. For
+example, \xdc is exactly the same as \x{dc}.
+

+

+After \0 up to two further octal digits are read. If there are fewer than two
+digits, just those that are present are used. Thus the sequence \0\x\07
+specifies two binary zeros followed by a BEL character (code value 7). Make
+sure you supply two digits after the initial zero if the pattern character that
+follows is itself an octal digit.
+

+

+The handling of a backslash followed by a digit other than 0 is complicated.
+Outside a character class, PCRE reads it and any following digits as a decimal
+number. If the number is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the entire sequence is
+taken as a back reference. A description of how this works is given
+later,
+following the discussion of
+parenthesized subpatterns.
+

+

+Inside a character class, or if the decimal number is greater than 9 and there
+have not been that many capturing subpatterns, PCRE re-reads up to three octal
+digits following the backslash, and uses them to generate a data character. Any
+subsequent digits stand for themselves. In non-UTF-8 mode, the value of a
+character specified in octal must be less than \400. In UTF-8 mode, values up
+to \777 are permitted. For example:
+
+  \040   is another way of writing a space
+  \40    is the same, provided there are fewer than 40 previous capturing subpatterns
+  \7     is always a back reference
+  \11    might be a back reference, or another way of writing a tab
+  \011   is always a tab
+  \0113  is a tab followed by the character "3"
+  \113   might be a back reference, otherwise the character with octal code 113
+  \377   might be a back reference, otherwise the byte consisting entirely of 1 bits
+  \81    is either a back reference, or a binary zero followed by the two characters "8" and "1"
+

+Note that octal values of 100 or greater must not be introduced by a leading
+zero, because no more than three octal digits are ever read.
+

+

+All the sequences that define a single character value can be used both inside
+and outside character classes. In addition, inside a character class, the
+sequence \b is interpreted as the backspace character (hex 08), and the
+sequences \R and \X are interpreted as the characters "R" and "X",
+respectively. Outside a character class, these sequences have different
+meanings
+(see below).
+

+

+Absolute and relative back references
+

+

+The sequence \g followed by an unsigned or a negative number, optionally
+enclosed in braces, is an absolute or relative back reference. A named back
+reference can be coded as \g{name}. Back references are discussed
+later,
+following the discussion of
+parenthesized subpatterns.
+

+

+Absolute and relative subroutine calls
+

+

+For compatibility with Oniguruma, the non-Perl syntax \g followed by a name or
+a number enclosed either in angle brackets or single quotes, is an alternative
+syntax for referencing a subpattern as a "subroutine". Details are discussed
+later.
+Note that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are not
+synonymous. The former is a back reference; the latter is a
+subroutine
+call.
+

+

+Generic character types
+

+

+Another use of backslash is for specifying generic character types. The
+following are always recognized:
+
+  \d     any decimal digit
+  \D     any character that is not a decimal digit
+  \h     any horizontal whitespace character
+  \H     any character that is not a horizontal whitespace character
+  \s     any whitespace character
+  \S     any character that is not a whitespace character
+  \v     any vertical whitespace character
+  \V     any character that is not a vertical whitespace character
+  \w     any "word" character
+  \W     any "non-word" character
+

+Each pair of escape sequences partitions the complete set of characters into
+two disjoint sets. Any given character matches one, and only one, of each pair.
+

+

+These character type sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, since
+there is no character to match.
+

+

+For compatibility with Perl, \s does not match the VT character (code 11).
+This makes it different from the the POSIX "space" class. The \s characters
+are HT (9), LF (10), FF (12), CR (13), and space (32). If "use locale;" is
+included in a Perl script, \s may match the VT character. In PCRE, it never
+does.
+

+

+In UTF-8 mode, characters with values greater than 128 never match \d, \s, or
+\w, and always match \D, \S, and \W. This is true even when Unicode
+character property support is available. These sequences retain their original
+meanings from before UTF-8 support was available, mainly for efficiency
+reasons. Note that this also affects \b, because it is defined in terms of \w
+and \W.
+

+

+The sequences \h, \H, \v, and \V are Perl 5.10 features. In contrast to the
+other sequences, these do match certain high-valued codepoints in UTF-8 mode.
+The horizontal space characters are:
+
+  U+0009     Horizontal tab
+  U+0020     Space
+  U+00A0     Non-break space
+  U+1680     Ogham space mark
+  U+180E     Mongolian vowel separator
+  U+2000     En quad
+  U+2001     Em quad
+  U+2002     En space
+  U+2003     Em space
+  U+2004     Three-per-em space
+  U+2005     Four-per-em space
+  U+2006     Six-per-em space
+  U+2007     Figure space
+  U+2008     Punctuation space
+  U+2009     Thin space
+  U+200A     Hair space
+  U+202F     Narrow no-break space
+  U+205F     Medium mathematical space
+  U+3000     Ideographic space
+

+The vertical space characters are:
+
+  U+000A     Linefeed
+  U+000B     Vertical tab
+  U+000C     Formfeed
+  U+000D     Carriage return
+  U+0085     Next line
+  U+2028     Line separator
+  U+2029     Paragraph separator
+

+

+

+A "word" character is an underscore or any character less than 256 that is a
+letter or digit. The definition of letters and digits is controlled by PCRE's
+low-valued character tables, and may vary if locale-specific matching is taking
+place (see
+"Locale support"
+in the
+pcreapi
+page). For example, in a French locale such as "fr_FR" in Unix-like systems,
+or "french" in Windows, some character codes greater than 128 are used for
+accented letters, and these are matched by \w. The use of locales with Unicode
+is discouraged.
+

+

+Newline sequences
+

+

+Outside a character class, by default, the escape sequence \R matches any
+Unicode newline sequence. This is a Perl 5.10 feature. In non-UTF-8 mode \R is
+equivalent to the following:
+
+  (?>\r\n|\n|\x0b|\f|\r|\x85)
+

+This is an example of an "atomic group", details of which are given
+below.
+This particular group matches either the two-character sequence CR followed by
+LF, or one of the single characters LF (linefeed, U+000A), VT (vertical tab,
+U+000B), FF (formfeed, U+000C), CR (carriage return, U+000D), or NEL (next
+line, U+0085). The two-character sequence is treated as a single unit that
+cannot be split.
+

+

+In UTF-8 mode, two additional characters whose codepoints are greater than 255
+are added: LS (line separator, U+2028) and PS (paragraph separator, U+2029).
+Unicode character property support is not needed for these characters to be
+recognized.
+

+

+It is possible to restrict \R to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE_BSR_ANYCRLF
+either at compile time or when the pattern is matched. (BSR is an abbrevation
+for "backslash R".) This can be made the default when PCRE is built; if this is
+the case, the other behaviour can be requested via the PCRE_BSR_UNICODE option.
+It is also possible to specify these settings by starting a pattern string with
+one of the following sequences:
+
+  (*BSR_ANYCRLF)   CR, LF, or CRLF only
+  (*BSR_UNICODE)   any Unicode newline sequence
+

+These override the default and the options given to pcre_compile() or
+pcre_compile2(), but they can be overridden by options given to
+pcre_exec() or pcre_dfa_exec(). Note that these special settings,
+which are not Perl-compatible, are recognized only at the very start of a
+pattern, and that they must be in upper case. If more than one of them is
+present, the last one is used. They can be combined with a change of newline
+convention, for example, a pattern can start with:
+
+  (*ANY)(*BSR_ANYCRLF)
+

+Inside a character class, \R matches the letter "R".
+

+

+Unicode character properties
+

+

+When PCRE is built with Unicode character property support, three additional
+escape sequences that match characters with specific properties are available.
+When not in UTF-8 mode, these sequences are of course limited to testing
+characters whose codepoints are less than 256, but they do work in this mode.
+The extra escape sequences are:
+
+  \p{xx}   a character with the xx property
+  \P{xx}   a character without the xx property
+  \X       an extended Unicode sequence
+

+The property names represented by xx above are limited to the Unicode
+script names, the general category properties, and "Any", which matches any
+character (including newline). Other properties such as "InMusicalSymbols" are
+not currently supported by PCRE. Note that \P{Any} does not match any
+characters, so always causes a match failure.
+

+

+Sets of Unicode characters are defined as belonging to certain scripts. A
+character from one of these sets can be matched using a script name. For
+example:
+
+  \p{Greek}
+  \P{Han}
+

+Those that are not part of an identified script are lumped together as
+"Common". The current list of scripts is:
+

+

+Bopomofo,

+

+

+Each character has exactly one general category property, specified by a
+two-letter abbreviation. For compatibility with Perl, negation can be specified
+by including a circumflex between the opening brace and the property name. For
+example, \p{^Lu} is the same as \P{Lu}.
+

+

+If only one letter is specified with \p or \P, it includes all the general
+category properties that start with that letter. In this case, in the absence
+of negation, the curly brackets in the escape sequence are optional; these two
+examples have the same effect:
+
+  \p{L}
+  \pL
+

+The following general category property codes are supported:
+
+  C     Other
+  Cc    Control
+  Cf    Format
+  Cn    Unassigned
+  Co    Private use
+  Cs    Surrogate
+
+  L     Letter
+  Ll    Lower case letter
+  Lm    Modifier letter
+  Lo    Other letter
+  Lt    Title case letter
+  Lu    Upper case letter
+
+  M     Mark
+  Mc    Spacing mark
+  Me    Enclosing mark
+  Mn    Non-spacing mark
+
+  N     Number
+  Nd    Decimal number
+  Nl    Letter number
+  No    Other number
+
+  P     Punctuation
+  Pc    Connector punctuation
+  Pd    Dash punctuation
+  Pe    Close punctuation
+  Pf    Final punctuation
+  Pi    Initial punctuation
+  Po    Other punctuation
+  Ps    Open punctuation
+
+  S     Symbol
+  Sc    Currency symbol
+  Sk    Modifier symbol
+  Sm    Mathematical symbol
+  So    Other symbol
+
+  Z     Separator
+  Zl    Line separator
+  Zp    Paragraph separator
+  Zs    Space separator
+

+The special property L& is also supported: it matches a character that has
+the Lu, Ll, or Lt property, in other words, a letter that is not classified as
+a modifier or "other".
+

+

+The Cs (Surrogate) property applies only to characters in the range U+D800 to
+U+DFFF. Such characters are not valid in UTF-8 strings (see RFC 3629) and so
+cannot be tested by PCRE, unless UTF-8 validity checking has been turned off
+(see the discussion of PCRE_NO_UTF8_CHECK in the
+pcreapi
+page). Perl does not support the Cs property.
+

+

+The long synonyms for property names that Perl supports (such as \p{Letter})
+are not supported by PCRE, nor is it permitted to prefix any of these
+properties with "Is".
+

+

+No character that is in the Unicode table has the Cn (unassigned) property.
+Instead, this property is assumed for any code point that is not in the
+Unicode table.
+

+

+Specifying caseless matching does not affect these escape sequences. For
+example, \p{Lu} always matches only upper case letters.
+

+

+The \X escape matches any number of Unicode characters that form an extended
+Unicode sequence. \X is equivalent to
+
+  (?>\PM\pM*)
+

+That is, it matches a character without the "mark" property, followed by zero
+or more characters with the "mark" property, and treats the sequence as an
+atomic group
+(see below).
+Characters with the "mark" property are typically accents that affect the
+preceding character. None of them have codepoints less than 256, so in
+non-UTF-8 mode \X matches any one character.
+

+

+Matching characters by Unicode property is not fast, because PCRE has to search
+a structure that contains data for over fifteen thousand characters. That is
+why the traditional escape sequences such as \d and \w do not use Unicode
+properties in PCRE.
+

+

+Resetting the match start
+

+

+The escape sequence \K, which is a Perl 5.10 feature, causes any previously
+matched characters not to be included in the final matched sequence. For
+example, the pattern:
+
+  foo\Kbar
+

+matches "foobar", but reports that it has matched "bar". This feature is
+similar to a lookbehind assertion
+(described below).
+However, in this case, the part of the subject before the real match does not
+have to be of fixed length, as lookbehind assertions do. The use of \K does
+not interfere with the setting of
+captured substrings.
+For example, when the pattern
+
+  (foo)\Kbar
+

+matches "foobar", the first substring is still set to "foo".
+

+

+Simple assertions
+

+

+The final use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described
+below.
+The backslashed assertions are:
+
+  \b     matches at a word boundary
+  \B     matches when not at a word boundary
+  \A     matches at the start of the subject
+  \Z     matches at the end of the subject
+          also matches before a newline at the end of the subject
+  \z     matches only at the end of the subject
+  \G     matches at the first matching position in the subject
+

+These assertions may not appear in character classes (but note that \b has a
+different meaning, namely the backspace character, inside a character class).
+

+

+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \w or \W (i.e. one matches
+\w and the other matches \W), or the start or end of the string if the
+first or last character matches \w, respectively. Neither PCRE nor Perl has a
+separte "start of word" or "end of word" metasequence. However, whatever
+follows \b normally determines which it is. For example, the fragment
+\ba matches "a" at the start of a word.
+

+

+The \A, \Z, and \z assertions differ from the traditional circumflex and
+dollar (described in the next section) in that they only ever match at the very
+start and end of the subject string, whatever options are set. Thus, they are
+independent of multiline mode. These three assertions are not affected by the
+PCRE_NOTBOL or PCRE_NOTEOL options, which affect only the behaviour of the
+circumflex and dollar metacharacters. However, if the startoffset
+argument of pcre_exec() is non-zero, indicating that matching is to start
+at a point other than the beginning of the subject, \A can never match. The
+difference between \Z and \z is that \Z matches before a newline at the end
+of the string as well as at the very end, whereas \z matches only at the end.
+

+

+The \G assertion is true only when the current matching position is at the
+start point of the match, as specified by the startoffset argument of
+pcre_exec(). It differs from \A when the value of startoffset is
+non-zero. By calling pcre_exec() multiple times with appropriate
+arguments, you can mimic Perl's /g option, and it is in this kind of
+implementation where \G can be useful.
+

+

+Note, however, that PCRE's interpretation of \G, as the start of the current
+match, is subtly different from Perl's, which defines it as the end of the
+previous match. In Perl, these can be different when the previously matched
+string was empty. Because PCRE does just one match at a time, it cannot
+reproduce this behaviour.
+

+

+If all the alternatives of a pattern begin with \G, the expression is anchored
+to the starting match position, and the "anchored" flag is set in the compiled
+regular expression.
+

+
CIRCUMFLEX AND DOLLAR

+

+Outside a character class, in the default matching mode, the circumflex
+character is an assertion that is true only if the current matching point is
+at the start of the subject string. If the startoffset argument of
+pcre_exec() is non-zero, circumflex can never match if the PCRE_MULTILINE
+option is unset. Inside a character class, circumflex has an entirely different
+meaning
+(see below).
+

+

+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+

+

+A dollar character is an assertion that is true only if the current matching
+point is at the end of the subject string, or immediately before a newline
+at the end of the string (by default). Dollar need not be the last character of
+the pattern if a number of alternatives are involved, but it should be the last
+item in any branch in which it appears. Dollar has no special meaning in a
+character class.
+

+

+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE_DOLLAR_ENDONLY option at compile time. This
+does not affect the \Z assertion.
+

+

+The meanings of the circumflex and dollar characters are changed if the
+PCRE_MULTILINE option is set. When this is the case, a circumflex matches
+immediately after internal newlines as well as at the start of the subject
+string. It does not match after a newline that ends the string. A dollar
+matches before any newlines in the string, as well as at the very end, when
+PCRE_MULTILINE is set. When newline is specified as the two-character
+sequence CRLF, isolated CR and LF characters do not indicate newlines.
+

+

+For example, the pattern /^abc$/ matches the subject string "def\nabc" (where
+\n represents a newline) in multiline mode, but not otherwise. Consequently,
+patterns that are anchored in single line mode because all branches start with
+^ are not anchored in multiline mode, and a match for circumflex is possible
+when the startoffset argument of pcre_exec() is non-zero. The
+PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set.
+

+

+Note that the sequences \A, \Z, and \z can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\A it is always anchored, whether or not PCRE_MULTILINE is set.
+

+
FULL STOP (PERIOD, DOT)

+

+Outside a character class, a dot in the pattern matches any one character in
+the subject string except (by default) a character that signifies the end of a
+line. In UTF-8 mode, the matched character may be more than one byte long.
+

+

+When a line ending is defined as a single character, dot never matches that
+character; when the two-character sequence CRLF is used, dot does not match CR
+if it is immediately followed by LF, but otherwise it matches all characters
+(including isolated CRs and LFs). When any Unicode line endings are being
+recognized, dot does not match CR or LF or any of the other line ending
+characters.
+

+

+The behaviour of dot with regard to newlines can be changed. If the PCRE_DOTALL
+option is set, a dot matches any one character, without exception. If the
+two-character sequence CRLF is present in the subject string, it takes two dots
+to match it.
+

+

+The handling of dot is entirely independent of the handling of circumflex and
+dollar, the only relationship being that they both involve newlines. Dot has no
+special meaning in a character class.
+

+
MATCHING A SINGLE BYTE

+

+Outside a character class, the escape sequence \C matches any one byte, both
+in and out of UTF-8 mode. Unlike a dot, it always matches any line-ending
+characters. The feature is provided in Perl in order to match individual bytes
+in UTF-8 mode. Because it breaks up UTF-8 characters into individual bytes,
+what remains in the string may be a malformed UTF-8 string. For this reason,
+the \C escape sequence is best avoided.
+

+

+PCRE does not allow \C to appear in lookbehind assertions
+(described below),
+because in UTF-8 mode this would make it impossible to calculate the length of
+the lookbehind.
+

+
SQUARE BRACKETS AND CHARACTER CLASSES

+

+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special by default.
+However, if the PCRE_JAVASCRIPT_COMPAT option is set, a lone closing square
+bracket causes a compile-time error. If a closing square bracket is required as
+a member of the class, it should be the first data character in the class
+(after an initial circumflex, if present) or escaped with a backslash.
+

+

+A character class matches a single character in the subject. In UTF-8 mode, the
+character may be more than one byte long. A matched character must be in the
+set of characters defined by the class, unless the first character in the class
+definition is a circumflex, in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually required as a member
+of the class, ensure it is not the first character, or escape it with a
+backslash.
+

+

+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters that
+are in the class by enumerating those that are not. A class that starts with a
+circumflex is not an assertion; it still consumes a character from the subject
+string, and therefore it fails if the current pointer is at the end of the
+string.
+

+

+In UTF-8 mode, characters with values greater than 255 can be included in a
+class as a literal string of bytes, or by using the \x{ escaping mechanism.
+

+

+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would. In UTF-8 mode, PCRE always understands the concept of
+case for characters whose values are less than 128, so caseless matching is
+always possible. For characters with higher values, the concept of case is
+supported if PCRE is compiled with Unicode property support, but not otherwise.
+If you want to use caseless matching in UTF8-mode for characters 128 and above,
+you must ensure that PCRE is compiled with Unicode property support as well as
+with UTF-8 support.
+

+

+Characters that might indicate line breaks are never treated in any special way
+when matching character classes, whatever line-ending sequence is in use, and
+whatever setting of the PCRE_DOTALL and PCRE_MULTILINE options is used. A class
+such as [^a] always matches one of these characters.
+

+

+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class.
+

+

+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\]46] is interpreted as a class containing a range
+followed by two other characters. The octal or hexadecimal representation of
+"]" can also be used to end a range.
+

+

+Ranges operate in the collating sequence of character values. They can also be
+used for characters specified numerically, for example [\000-\037]. In UTF-8
+mode, ranges can include characters whose values are greater than 255, for
+example [\x{100}-\x{2ff}].
+

+

+If a range that includes letters is used when caseless matching is set, it
+matches the letters in either case. For example, [W-c] is equivalent to
+[][\\^_`wxyzabc], matched caselessly, and in non-UTF-8 mode, if character
+tables for a French locale are in use, [\xc8-\xcb] matches accented E
+characters in both cases. In UTF-8 mode, PCRE supports the concept of case for
+characters with values greater than 128 only when it is compiled with Unicode
+property support.
+

+

+The character types \d, \D, \p, \P, \s, \S, \w, and \W may also appear
+in a character class, and add the characters that they match to the class. For
+example, [\dABCDEF] matches any hexadecimal digit. A circumflex can
+conveniently be used with the upper case character types to specify a more
+restricted set of characters than the matching lower case type. For example,
+the class [^\W_] matches any letter or digit, but not underscore.
+

+

+The only metacharacters that are recognized in character classes are backslash,
+hyphen (only where it can be interpreted as specifying a range), circumflex
+(only at the start), opening square bracket (only when it can be interpreted as
+introducing a POSIX class name - see the next section), and the terminating
+closing square bracket. However, escaping other non-alphanumeric characters
+does no harm.
+

+
POSIX CHARACTER CLASSES

+

+Perl supports the POSIX notation for character classes. This uses names
+enclosed by [: and :] within the enclosing square brackets. PCRE also supports
+this notation. For example,
+
+  [01[:alpha:]%]
+

+matches "0", "1", any alphabetic character, or "%". The supported class names
+are
+
+  alnum    letters and digits
+  alpha    letters
+  ascii    character codes 0 - 127
+  blank    space or tab only
+  cntrl    control characters
+  digit    decimal digits (same as \d)
+  graph    printing characters, excluding space
+  lower    lower case letters
+  print    printing characters, including space
+  punct    printing characters, excluding letters and digits
+  space    white space (not quite the same as \s)
+  upper    upper case letters
+  word     "word" characters (same as \w)
+  xdigit   hexadecimal digits
+

+The "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13), and
+space (32). Notice that this list includes the VT character (code 11). This
+makes "space" different to \s, which does not include VT (for Perl
+compatibility).
+

+

+The name "word" is a Perl extension, and "blank" is a GNU extension from Perl
+5.8. Another Perl extension is negation, which is indicated by a ^ character
+after the colon. For example,
+
+  [12[:^digit:]]
+

+matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+

+

+In UTF-8 mode, characters with values greater than 128 do not match any of
+the POSIX character classes.
+

+
VERTICAL BAR

+

+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+
+  gilbert|sullivan
+

+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string). The matching
+process tries each alternative in turn, from left to right, and the first one
+that succeeds is used. If the alternatives are within a subpattern
+(defined below),
+"succeeds" means matching the rest of the main pattern as well as the
+alternative in the subpattern.
+

+
INTERNAL OPTION SETTING

+

+The settings of the PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and
+PCRE_EXTENDED options (which are Perl-compatible) can be changed from within
+the pattern by a sequence of Perl option letters enclosed between "(?" and ")".
+The option letters are
+
+  i  for PCRE_CASELESS
+  m  for PCRE_MULTILINE
+  s  for PCRE_DOTALL
+  x  for PCRE_EXTENDED
+

+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and
+PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset.
+

+

+The PCRE-specific options PCRE_DUPNAMES, PCRE_UNGREEDY, and PCRE_EXTRA can be
+changed in the same way as the Perl-compatible options by using the characters
+J, U and X respectively.
+

+

+When one of these option changes occurs at top level (that is, not inside
+subpattern parentheses), the change applies to the remainder of the pattern
+that follows. If the change is placed right at the start of a pattern, PCRE
+extracts it into the global options (and it will therefore show up in data
+extracted by the pcre_fullinfo() function).
+

+

+An option change within a subpattern (see below for a description of
+subpatterns) affects only that part of the current pattern that follows it, so
+
+  (a(?i)b)c
+

+matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+
+  (a(?i)b|c)
+

+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+

+

+Note: There are other PCRE-specific options that can be set by the
+application when the compile or match functions are called. In some cases the
+pattern can contain special leading sequences such as (*CRLF) to override what
+the application has set or what has been defaulted. Details are given in the
+section entitled
+"Newline sequences"
+above. There is also the (*UTF8) leading sequence that can be used to set UTF-8
+mode; this is equivalent to setting the PCRE_UTF8 option.
+

+
SUBPATTERNS

+

+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Turning part of a pattern into a subpattern does two things:
+

+

+1. It localizes a set of alternatives. For example, the pattern
+
+  cat(aract|erpillar|)
+

+matches one of the words "cat", "cataract", or "caterpillar". Without the
+parentheses, it would match "cataract", "erpillar" or an empty string.
+

+

+2. It sets up the subpattern as a capturing subpattern. This means that, when
+the whole pattern matches, that portion of the subject string that matched the
+subpattern is passed back to the caller via the ovector argument of
+pcre_exec(). Opening parentheses are counted from left to right (starting
+from 1) to obtain numbers for the capturing subpatterns.
+

+

+For example, if the string "the red king" is matched against the pattern
+
+  the ((red|white) (king|queen))
+

+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+

+

+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by a question mark
+and a colon, the subpattern does not do any capturing, and is not counted when
+computing the number of any subsequent capturing subpatterns. For example, if
+the string "the white queen" is matched against the pattern
+
+  the ((?:red|white) (king|queen))
+

+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of capturing subpatterns is 65535.
+

+

+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+
+  (?i:saturday|sunday)
+  (?:(?i)saturday|sunday)
+

+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+

+
DUPLICATE SUBPATTERN NUMBERS

+

+Perl 5.10 introduced a feature whereby each alternative in a subpattern uses
+the same numbers for its capturing parentheses. Such a subpattern starts with
+(?| and is itself a non-capturing subpattern. For example, consider this
+pattern:
+
+  (?|(Sat)ur|(Sun))day
+

+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+buffers that follow the subpattern start after the highest number used in any
+branch. The following example is taken from the Perl documentation.
+The numbers underneath show in which buffer the captured content will be
+stored.
+
+  # before  ---------------branch-reset----------- after
+  / ( a )  (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+  # 1            2         2  3        2     3     4
+

+A backreference to a numbered subpattern uses the most recent value that is set
+for that number by any subpattern. The following pattern matches "abcabc" or
+"defdef":
+
+  /(?|(abc)|(def))\1/
+

+In contrast, a recursive or "subroutine" call to a numbered subpattern always
+refers to the first one in the pattern with the given number. The following
+pattern matches "abcabc" or "defabc":
+
+  /(?|(abc)|(def))(?1)/
+

+If a
+condition test
+for a subpattern's having matched refers to a non-unique number, the test is
+true if any of the subpatterns of that number have matched.
+

+

+An alternative approach to using this "branch reset" feature is to use
+duplicate named subpatterns, as described in the next section.
+

+
NAMED SUBPATTERNS

+

+Identifying capturing parentheses by number is simple, but it can be very hard
+to keep track of the numbers in complicated regular expressions. Furthermore,
+if an expression is modified, the numbers may change. To help with this
+difficulty, PCRE supports the naming of subpatterns. This feature was not
+added to Perl until release 5.10. Python had the feature earlier, and PCRE
+introduced it at release 4.0, using the Python syntax. PCRE now supports both
+the Perl and the Python syntax. Perl allows identically numbered subpatterns to
+have different names, but PCRE does not.
+

+

+In PCRE, a subpattern can be named in one of three ways: (?<name>...) or
+(?'name'...) as in Perl, or (?P<name>...) as in Python. References to capturing
+parentheses from other parts of the pattern, such as
+backreferences,
+recursion,
+and
+conditions,
+can be made by name as well as by number.
+

+

+Names consist of up to 32 alphanumeric characters and underscores. Named
+capturing parentheses are still allocated numbers as well as names, exactly as
+if the names were not present. The PCRE API provides function calls for
+extracting the name-to-number translation table from a compiled pattern. There
+is also a convenience function for extracting a captured substring by name.
+

+

+By default, a name must be unique within a pattern, but it is possible to relax
+this constraint by setting the PCRE_DUPNAMES option at compile time. (Duplicate
+names are also always permitted for subpatterns with the same number, set up as
+described in the previous section.) Duplicate names can be useful for patterns
+where only one instance of the named parentheses can match. Suppose you want to
+match the name of a weekday, either as a 3-letter abbreviation or as the full
+name, and in both cases you want to extract the abbreviation. This pattern
+(ignoring the line breaks) does the job:
+
+  (?<DN>Mon|Fri|Sun)(?:day)?|
+  (?<DN>Tue)(?:sday)?|
+  (?<DN>Wed)(?:nesday)?|
+  (?<DN>Thu)(?:rsday)?|
+  (?<DN>Sat)(?:urday)?
+

+There are five capturing substrings, but only one is ever set after a match.
+(An alternative way of solving this problem is to use a "branch reset"
+subpattern, as described in the previous section.)
+

+

+The convenience function for extracting the data by name returns the substring
+for the first (and in this example, the only) subpattern of that name that
+matched. This saves searching to find which numbered subpattern it was.
+

+

+If you make a backreference to a non-unique named subpattern from elsewhere in
+the pattern, the one that corresponds to the first occurrence of the name is
+used. In the absence of duplicate numbers (see the previous section) this is
+the one with the lowest number. If you use a named reference in a condition
+test (see the
+section about conditions
+below), either to check whether a subpattern has matched, or to check for
+recursion, all subpatterns with the same name are tested. If the condition is
+true for any one of them, the overall condition is true. This is the same
+behaviour as testing by number. For further details of the interfaces for
+handling named subpatterns, see the
+pcreapi
+documentation.
+

+

+Warning: You cannot use different names to distinguish between two
+subpatterns with the same number because PCRE uses only the numbers when
+matching. For this reason, an error is given at compile time if different names
+are given to subpatterns with the same number. However, you can give the same
+name to subpatterns with the same number, even when PCRE_DUPNAMES is not set.
+

+
REPETITION

+

+Repetition is specified by quantifiers, which can follow any of the following
+items:
+
+  a literal data character
+  the dot metacharacter
+  the \C escape sequence
+  the \X escape sequence (in UTF-8 mode with Unicode properties)
+  the \R escape sequence
+  an escape such as \d that matches a single character
+  a character class
+  a back reference (see next section)
+  a parenthesized subpattern (unless it is an assertion)
+  a recursive or "subroutine" call to a subpattern
+

+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+
+  z{2,4}
+

+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+
+  [aeiou]{3,}
+

+matches at least 3 successive vowels, but may match many more, while
+
+  \d{8}
+

+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+

+

+In UTF-8 mode, quantifiers apply to UTF-8 characters rather than to individual
+bytes. Thus, for example, \x{100}{2} matches two UTF-8 characters, each of
+which is represented by a two-byte sequence. Similarly, when Unicode property
+support is available, \X{3} matches three Unicode extended sequences, each of
+which may be several bytes long (and they may be of different lengths).
+

+

+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present. This may be useful for
+subpatterns that are referenced as
+subroutines
+from elsewhere in the pattern. Items other than subpatterns that have a {0}
+quantifier are omitted from the compiled pattern.
+

+

+For convenience, the three most common quantifiers have single-character
+abbreviations:
+
+  *    is equivalent to {0,}
+  +    is equivalent to {1,}
+  ?    is equivalent to {0,1}
+

+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+
+  (a?)*
+

+Earlier versions of Perl and PCRE used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+

+

+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between /* and */
+and within the comment, individual * and / characters may appear. An attempt to
+match C comments by applying the pattern
+
+  /\*.*\*/
+

+to the string
+
+  /* first comment */  not comment  /* second comment */
+

+fails, because it matches the entire string owing to the greediness of the .*
+item.
+

+

+However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+
+  /\*.*?\*/
+

+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+
+  \d??\d
+

+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+

+

+If the PCRE_UNGREEDY option is set (an option that is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+

+

+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more memory is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+

+

+If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the dot to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE normally treats such a
+pattern as though it were preceded by \A.
+

+

+In cases where it is known that the subject string contains no newlines, it is
+worth setting PCRE_DOTALL in order to obtain this optimization, or
+alternatively using ^ to indicate anchoring explicitly.
+

+

+However, there is one situation where the optimization cannot be used. When .*
+is inside capturing parentheses that are the subject of a backreference
+elsewhere in the pattern, a match at the start may fail where a later one
+succeeds. Consider, for example:
+
+  (.*)abc\1
+

+If the subject is "xyz123abc123" the match point is the fourth character. For
+this reason, such a pattern is not implicitly anchored.
+

+

+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+
+  (tweedle[dume]{3}\s*)+
+

+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+
+  /(a|(b))+/
+

+matches "aba" the value of the second captured substring is "b".
+

+
ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS

+

+With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+repetition, failure of what follows normally causes the repeated item to be
+re-evaluated to see if a different number of repeats allows the rest of the
+pattern to match. Sometimes it is useful to prevent this, either to change the
+nature of the match, or to cause it fail earlier than it otherwise might, when
+the author of the pattern knows there is no point in carrying on.
+

+

+Consider, for example, the pattern \d+foo when applied to the subject line
+
+  123456bar
+

+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \d+
+item, and then with 4, and so on, before ultimately failing. "Atomic grouping"
+(a term taken from Jeffrey Friedl's book) provides the means for specifying
+that once a subpattern has matched, it is not to be re-evaluated in this way.
+

+

+If we use atomic grouping for the previous example, the matcher gives up
+immediately on failing to match "foo" the first time. The notation is a kind of
+special parenthesis, starting with (?> as in this example:
+
+  (?>\d+)foo
+

+This kind of parenthesis "locks up" the  part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+

+

+An alternative description is that a subpattern of this type matches the string
+of characters that an identical standalone pattern would match, if anchored at
+the current point in the subject string.
+

+

+Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as
+the above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \d+ and \d+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?>\d+) can only match an entire sequence of digits.
+

+

+Atomic groups in general can of course contain arbitrarily complicated
+subpatterns, and can be nested. However, when the subpattern for an atomic
+group is just a single repeated item, as in the example above, a simpler
+notation, called a "possessive quantifier" can be used. This consists of an
+additional + character following a quantifier. Using this notation, the
+previous example can be rewritten as
+
+  \d++foo
+

+Note that a possessive quantifier can be used with an entire group, for
+example:
+
+  (abc|xyz){2,3}+
+

+Possessive quantifiers are always greedy; the setting of the PCRE_UNGREEDY
+option is ignored. They are a convenient notation for the simpler forms of
+atomic group. However, there is no difference in the meaning of a possessive
+quantifier and the equivalent atomic group, though there may be a performance
+difference; possessive quantifiers should be slightly faster.
+

+

+The possessive quantifier syntax is an extension to the Perl 5.8 syntax.
+Jeffrey Friedl originated the idea (and the name) in the first edition of his
+book. Mike McCloskey liked it, so implemented it when he built Sun's Java
+package, and PCRE copied it from there. It ultimately found its way into Perl
+at release 5.10.
+

+

+PCRE has an optimization that automatically "possessifies" certain simple
+pattern constructs. For example, the sequence A+B is treated as A++B because
+there is no point in backtracking into a sequence of A's when B must follow.
+

+

+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of an atomic group is the
+only way to avoid some failing matches taking a very long time indeed. The
+pattern
+
+  (\D+|<\d+>)*[!?]
+

+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+
+  aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+

+it takes a long time before reporting failure. This is because the string can
+be divided between the internal \D+ repeat and the external * repeat in a
+large number of ways, and all have to be tried. (The example uses [!?] rather
+than a single character at the end, because both PCRE and Perl have an
+optimization that allows for fast failure when a single character is used. They
+remember the last single character that is required for a match, and fail early
+if it is not present in the string.) If the pattern is changed so that it uses
+an atomic group, like this:
+
+  ((?>\D+)|<\d+>)*[!?]
+

+sequences of non-digits cannot be broken, and failure happens quickly.
+

+
BACK REFERENCES

+

+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(that is, to its left) in the pattern, provided there have been that many
+previous capturing left parentheses.
+

+

+However, if the decimal number following the backslash is less than 10, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 10. A "forward back reference" of this type can make sense
+when a repetition is involved and the subpattern to the right has participated
+in an earlier iteration.
+

+

+It is not possible to have a numerical "forward back reference" to a subpattern
+whose number is 10 or more using this syntax because a sequence such as \50 is
+interpreted as a character defined in octal. See the subsection entitled
+"Non-printing characters"
+above
+for further details of the handling of digits following a backslash. There is
+no such problem when named parentheses are used. A back reference to any
+subpattern is possible using named parentheses (see below).
+

+

+Another way of avoiding the ambiguity inherent in the use of digits following a
+backslash is to use the \g escape sequence, which is a feature introduced in
+Perl 5.10. This escape must be followed by an unsigned number or a negative
+number, optionally enclosed in braces. These examples are all identical:
+
+  (ring), \1
+  (ring), \g1
+  (ring), \g{1}
+

+An unsigned number specifies an absolute reference without the ambiguity that
+is present in the older syntax. It is also useful when literal digits follow
+the reference. A negative number is a relative reference. Consider this
+example:
+
+  (abc(def)ghi)\g{-1}
+

+The sequence \g{-1} is a reference to the most recently started capturing
+subpattern before \g, that is, is it equivalent to \2. Similarly, \g{-2}
+would be equivalent to \1. The use of relative references can be helpful in
+long patterns, and also in patterns that are created by joining together
+fragments that contain references within themselves.
+

+

+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself (see
+"Subpatterns as subroutines"
+below for a way of doing that). So the pattern
+
+  (sens|respons)e and \1ibility
+

+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+
+  ((?i)rah)\s+\1
+

+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+

+

+There are several different ways of writing back references to named
+subpatterns. The .NET syntax \k{name} and the Perl syntax \k<name> or
+\k'name' are supported, as is the Python syntax (?P=name). Perl 5.10's unified
+back reference syntax, in which \g can be used for both numeric and named
+references, is also supported. We could rewrite the above example in any of
+the following ways:
+
+  (?<p1>(?i)rah)\s+\k<p1>
+  (?'p1'(?i)rah)\s+\k{p1}
+  (?P<p1>(?i)rah)\s+(?P=p1)
+  (?<p1>(?i)rah)\s+\g{p1}
+

+A subpattern that is referenced by name may appear in the pattern before or
+after the reference.
+

+

+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail by default. For example, the pattern
+
+  (a|(bc))\2
+

+always fails if it starts to match "a" rather than "bc". However, if the
+PCRE_JAVASCRIPT_COMPAT option is set at compile time, a back reference to an
+unset value matches an empty string.
+

+

+Because there may be many capturing parentheses in a pattern, all digits
+following a backslash are taken as part of a potential back reference number.
+If the pattern continues with a digit character, some delimiter must be used to
+terminate the back reference. If the PCRE_EXTENDED option is set, this can be
+whitespace. Otherwise, the \g{ syntax or an empty comment (see
+"Comments"
+below) can be used.
+

+

+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+
+  (a|b\1)+
+

+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+

+
ASSERTIONS

+

+An assertion is a test on the characters following or preceding the current
+matching point that does not actually consume any characters. The simple
+assertions coded as \b, \B, \A, \G, \Z, \z, ^ and $ are described
+above.
+

+

+More complicated assertions are coded as subpatterns. There are two kinds:
+those that look ahead of the current position in the subject string, and those
+that look behind it. An assertion subpattern is matched in the normal way,
+except that it does not cause the current matching position to be changed.
+

+

+Assertion subpatterns are not capturing subpatterns, and may not be repeated,
+because it makes no sense to assert the same thing several times. If any kind
+of assertion contains capturing subpatterns within it, these are counted for
+the purposes of numbering the capturing subpatterns in the whole pattern.
+However, substring capturing is carried out only for positive assertions,
+because it does not make sense for negative assertions.
+

+

+Lookahead assertions
+

+

+Lookahead assertions start with (?= for positive assertions and (?! for
+negative assertions. For example,
+
+  \w+(?=;)
+

+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+
+  foo(?!bar)
+

+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+
+  (?!foo)bar
+

+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve the other effect.
+

+

+If you want to force a matching failure at some point in a pattern, the most
+convenient way to do it is with (?!) because an empty string always matches, so
+an assertion that requires there not to be an empty string must always fail.
+The Perl 5.10 backtracking control verb (*FAIL) or (*F) is essentially a
+synonym for (?!).
+

+

+Lookbehind assertions
+

+

+Lookbehind assertions start with (?<= for positive assertions and (?<! for
+negative assertions. For example,
+
+  (?<!foo)bar
+

+does find an occurrence of "bar" that is not preceded by "foo". The contents of
+a lookbehind assertion are restricted such that all the strings it matches must
+have a fixed length. However, if there are several top-level alternatives, they
+do not all have to have the same fixed length. Thus
+
+  (?<=bullock|donkey)
+

+is permitted, but
+
+  (?<!dogs?|cats?)
+

+causes an error at compile time. Branches that match different length strings
+are permitted only at the top level of a lookbehind assertion. This is an
+extension compared with Perl (5.8 and 5.10), which requires all branches to
+match the same length of string. An assertion such as
+
+  (?<=ab(c|de))
+

+is not permitted, because its single top-level branch can match two different
+lengths, but it is acceptable to PCRE if rewritten to use two top-level
+branches:
+
+  (?<=abc|abde)
+

+In some cases, the Perl 5.10 escape sequence \K
+(see above)
+can be used instead of a lookbehind assertion to get round the fixed-length
+restriction.
+

+

+The implementation of lookbehind assertions is, for each alternative, to
+temporarily move the current position back by the fixed length and then try to
+match. If there are insufficient characters before the current position, the
+assertion fails.
+

+

+PCRE does not allow the \C escape (which matches a single byte in UTF-8 mode)
+to appear in lookbehind assertions, because it makes it impossible to calculate
+the length of the lookbehind. The \X and \R escapes, which can match
+different numbers of bytes, are also not permitted.
+

+

+"Subroutine"
+calls (see below) such as (?2) or (?&X) are permitted in lookbehinds, as long
+as the subpattern matches a fixed-length string.
+Recursion,
+however, is not supported.
+

+

+Possessive quantifiers can be used in conjunction with lookbehind assertions to
+specify efficient matching of fixed-length strings at the end of subject
+strings. Consider a simple pattern such as
+
+  abcd$
+

+when applied to a long string that does not match. Because matching proceeds
+from left to right, PCRE will look for each "a" in the subject and then see if
+what follows matches the rest of the pattern. If the pattern is specified as
+
+  ^.*abcd$
+

+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+
+  ^.*+(?<=abcd)
+

+there can be no backtracking for the .*+ item; it can match only the entire
+string. The subsequent lookbehind assertion does a single test on the last four
+characters. If it fails, the match fails immediately. For long strings, this
+approach makes a significant difference to the processing time.
+

+

+Using multiple assertions
+

+

+Several assertions (of any sort) may occur in succession. For example,
+
+  (?<=\d{3})(?<!999)foo
+

+matches "foo" preceded by three digits that are not "999". Notice that each of
+the assertions is applied independently at the same point in the subject
+string. First there is a check that the previous three characters are all
+digits, and then there is a check that the same three characters are not "999".
+This pattern does not match "foo" preceded by six characters, the first
+of which are digits and the last three of which are not "999". For example, it
+doesn't match "123abcfoo". A pattern to do that is
+
+  (?<=\d{3}...)(?<!999)foo
+

+This time the first assertion looks at the preceding six characters, checking
+that the first three are digits, and then the second assertion checks that the
+preceding three characters are not "999".
+

+

+Assertions can be nested in any combination. For example,
+
+  (?<=(?<!foo)bar)baz
+

+matches an occurrence of "baz" that is preceded by "bar" which in turn is not
+preceded by "foo", while
+
+  (?<=\d{3}(?!999)...)foo
+

+is another pattern that matches "foo" preceded by three digits and any three
+characters that are not "999".
+

+
CONDITIONAL SUBPATTERNS

+

+It is possible to cause the matching process to obey a subpattern
+conditionally or to choose between two alternative subpatterns, depending on
+the result of an assertion, or whether a specific capturing subpattern has
+already been matched. The two possible forms of conditional subpattern are:
+
+  (?(condition)yes-pattern)
+  (?(condition)yes-pattern|no-pattern)
+

+If the condition is satisfied, the yes-pattern is used; otherwise the
+no-pattern (if present) is used. If there are more than two alternatives in the
+subpattern, a compile-time error occurs.
+

+

+There are four kinds of condition: references to subpatterns, references to
+recursion, a pseudo-condition called DEFINE, and assertions.
+

+

+Checking for a used subpattern by number
+

+

+If the text between the parentheses consists of a sequence of digits, the
+condition is true if a capturing subpattern of that number has previously
+matched. If there is more than one capturing subpattern with the same number
+(see the earlier
+section about duplicate subpattern numbers),
+the condition is true if any of them have been set. An alternative notation is
+to precede the digits with a plus or minus sign. In this case, the subpattern
+number is relative rather than absolute. The most recently opened parentheses
+can be referenced by (?(-1), the next most recent by (?(-2), and so on. In
+looping constructs it can also make sense to refer to subsequent groups with
+constructs such as (?(+2).
+

+

+Consider the following pattern, which contains non-significant white space to
+make it more readable (assume the PCRE_EXTENDED option) and to divide it into
+three parts for ease of discussion:
+
+  ( \( )?    [^()]+    (?(1) \) )
+

+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether the first set of parentheses matched
+or not. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the
+subpattern matches nothing. In other words, this pattern matches a sequence of
+non-parentheses, optionally enclosed in parentheses.
+

+

+If you were embedding this pattern in a larger one, you could use a relative
+reference:
+
+  ...other stuff... ( \( )?    [^()]+    (?(-1) \) ) ...
+

+This makes the fragment independent of the parentheses in the larger pattern.
+

+

+Checking for a used subpattern by name
+

+

+Perl uses the syntax (?(<name>)...) or (?('name')...) to test for a used
+subpattern by name. For compatibility with earlier versions of PCRE, which had
+this facility before Perl, the syntax (?(name)...) is also recognized. However,
+there is a possible ambiguity with this syntax, because subpattern names may
+consist entirely of digits. PCRE looks first for a named subpattern; if it
+cannot find one and the name consists entirely of digits, PCRE looks for a
+subpattern of that number, which must be greater than zero. Using subpattern
+names that consist entirely of digits is not recommended.
+

+

+Rewriting the above example to use a named subpattern gives this:
+
+  (?<OPEN> \( )?    [^()]+    (?(<OPEN>) \) )
+

+If the name used in a condition of this kind is a duplicate, the test is
+applied to all subpatterns of the same name, and is true if any one of them has
+matched.
+

+

+Checking for pattern recursion
+

+

+If the condition is the string (R), and there is no subpattern with the name R,
+the condition is true if a recursive call to the whole pattern or any
+subpattern has been made. If digits or a name preceded by ampersand follow the
+letter R, for example:
+
+  (?(R3)...) or (?(R&name)...)
+

+the condition is true if the most recent recursion is into a subpattern whose
+number or name is given. This condition does not check the entire recursion
+stack. If the name used in a condition of this kind is a duplicate, the test is
+applied to all subpatterns of the same name, and is true if any one of them is
+the most recent recursion.
+

+

+At "top level", all these recursion test conditions are false.
+The syntax for recursive patterns
+is described below.
+

+

+Defining subpatterns for use by reference only
+

+

+If the condition is the string (DEFINE), and there is no subpattern with the
+name DEFINE, the condition is always false. In this case, there may be only one
+alternative in the subpattern. It is always skipped if control reaches this
+point in the pattern; the idea of DEFINE is that it can be used to define
+"subroutines" that can be referenced from elsewhere. (The use of
+"subroutines"
+is described below.) For example, a pattern to match an IPv4 address could be
+written like this (ignore whitespace and line breaks):
+
+  (?(DEFINE) (?<byte> 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+  \b (?&byte) (\.(?&byte)){3} \b
+

+The first part of the pattern is a DEFINE group inside which a another group
+named "byte" is defined. This matches an individual component of an IPv4
+address (a number less than 256). When matching takes place, this part of the
+pattern is skipped because DEFINE acts like a false condition. The rest of the
+pattern uses references to the named group to match the four dot-separated
+components of an IPv4 address, insisting on a word boundary at each end.
+

+

+Assertion conditions
+

+

+If the condition is not in any of the above formats, it must be an assertion.
+This may be a positive or negative lookahead or lookbehind assertion. Consider
+this pattern, again containing non-significant white space, and with the two
+alternatives on the second line:
+
+  (?(?=[^a-z]*[a-z])
+  \d{2}-[a-z]{3}-\d{2}  |  \d{2}-\d{2}-\d{2} )
+

+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+

+
COMMENTS

+

+The sequence (?# marks the start of a comment that continues up to the next
+closing parenthesis. Nested parentheses are not permitted. The characters
+that make up a comment play no part in the pattern matching at all.
+

+

+If the PCRE_EXTENDED option is set, an unescaped # character outside a
+character class introduces a comment that continues to immediately after the
+next newline in the pattern.
+

+
RECURSIVE PATTERNS

+

+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth.
+

+

+For some time, Perl has provided a facility that allows regular expressions to
+recurse (amongst other things). It does this by interpolating Perl code in the
+expression at run time, and the code can refer to the expression itself. A Perl
+pattern using code interpolation to solve the parentheses problem can be
+created like this:
+
+  $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+

+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears.
+

+

+Obviously, PCRE cannot support the interpolation of Perl code. Instead, it
+supports special syntax for recursion of the entire pattern, and also for
+individual subpattern recursion. After its introduction in PCRE and Python,
+this kind of recursion was subsequently introduced into Perl at release 5.10.
+

+

+A special item that consists of (? followed by a number greater than zero and a
+closing parenthesis is a recursive call of the subpattern of the given number,
+provided that it occurs inside that subpattern. (If not, it is a
+"subroutine"
+call, which is described in the next section.) The special item (?R) or (?0) is
+a recursive call of the entire regular expression.
+

+

+This PCRE pattern solves the nested parentheses problem (assume the
+PCRE_EXTENDED option is set so that white space is ignored):
+
+  \( ( [^()]++ | (?R) )* \)
+

+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (that is, a correctly parenthesized substring).
+Finally there is a closing parenthesis. Note the use of a possessive quantifier
+to avoid backtracking into sequences of non-parentheses.
+

+

+If this were part of a larger pattern, you would not want to recurse the entire
+pattern, so instead you could use this:
+
+  ( \( ( [^()]++ | (?1) )* \) )
+

+We have put the pattern into parentheses, and caused the recursion to refer to
+them instead of the whole pattern.
+

+

+In a larger pattern, keeping track of parenthesis numbers can be tricky. This
+is made easier by the use of relative references (a Perl 5.10 feature).
+Instead of (?1) in the pattern above you can write (?-2) to refer to the second
+most recently opened parentheses preceding the recursion. In other words, a
+negative number counts capturing parentheses leftwards from the point at which
+it is encountered.
+

+

+It is also possible to refer to subsequently opened parentheses, by writing
+references such as (?+2). However, these cannot be recursive because the
+reference is not inside the parentheses that are referenced. They are always
+"subroutine"
+calls, as described in the next section.
+

+

+An alternative approach is to use named parentheses instead. The Perl syntax
+for this is (?&name); PCRE's earlier syntax (?P>name) is also supported. We
+could rewrite the above example as follows:
+
+  (?<pn> \( ( [^()]++ | (?&pn) )* \) )
+

+If there is more than one subpattern with the same name, the earliest one is
+used.
+

+

+This particular example pattern that we have been looking at contains nested
+unlimited repeats, and so the use of a possessive quantifier for matching
+strings of non-parentheses is important when applying the pattern to strings
+that do not match. For example, when this pattern is applied to
+
+  (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+

+it yields "no match" quickly. However, if a possessive quantifier is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+

+

+At the end of a match, the values of capturing parentheses are those from
+the outermost level. If you want to obtain intermediate values, a callout
+function can be used (see below and the
+pcrecallout
+documentation). If the pattern above is matched against
+
+  (ab(cd)ef)
+

+the value for the inner capturing parentheses (numbered 2) is "ef", which is
+the last value taken on at the top level. If a capturing subpattern is not
+matched at the top level, its final value is unset, even if it is (temporarily)
+set at a deeper level.
+

+

+If there are more than 15 capturing parentheses in a pattern, PCRE has to
+obtain extra memory to store data during a recursion, which it does by using
+pcre_malloc, freeing it via pcre_free afterwards. If no memory can
+be obtained, the match fails with the PCRE_ERROR_NOMEMORY error.
+

+

+Do not confuse the (?R) item with the condition (R), which tests for recursion.
+Consider this pattern, which matches text in angle brackets, allowing for
+arbitrary nesting. Only digits are allowed in nested brackets (that is, when
+recursing), whereas any characters are permitted at the outer level.
+
+  < (?: (?(R) \d++  | [^<>]*+) | (?R)) * >
+

+In this pattern, (?(R) is the start of a conditional subpattern, with two
+different alternatives for the recursive and non-recursive cases. The (?R) item
+is the actual recursive call.
+

+

+Recursion difference from Perl
+

+

+In PCRE (like Python, but unlike Perl), a recursive subpattern call is always
+treated as an atomic group. That is, once it has matched some of the subject
+string, it is never re-entered, even if it contains untried alternatives and
+there is a subsequent matching failure. This can be illustrated by the
+following pattern, which purports to match a palindromic string that contains
+an odd number of characters (for example, "a", "aba", "abcba", "abcdcba"):
+
+  ^(.|(.)(?1)\2)$
+

+The idea is that it either matches a single character, or two identical
+characters surrounding a sub-palindrome. In Perl, this pattern works; in PCRE
+it does not if the pattern is longer than three characters. Consider the
+subject string "abcba":
+

+

+At the top level, the first character is matched, but as it is not at the end
+of the string, the first alternative fails; the second alternative is taken
+and the recursion kicks in. The recursive call to subpattern 1 successfully
+matches the next character ("b"). (Note that the beginning and end of line
+tests are not part of the recursion).
+

+

+Back at the top level, the next character ("c") is compared with what
+subpattern 2 matched, which was "a". This fails. Because the recursion is
+treated as an atomic group, there are now no backtracking points, and so the
+entire match fails. (Perl is able, at this point, to re-enter the recursion and
+try the second alternative.) However, if the pattern is written with the
+alternatives in the other order, things are different:
+
+  ^((.)(?1)\2|.)$
+

+This time, the recursing alternative is tried first, and continues to recurse
+until it runs out of characters, at which point the recursion fails. But this
+time we do have another alternative to try at the higher level. That is the big
+difference: in the previous case the remaining alternative is at a deeper
+recursion level, which PCRE cannot use.
+

+

+To change the pattern so that matches all palindromic strings, not just those
+with an odd number of characters, it is tempting to change the pattern to this:
+
+  ^((.)(?1)\2|.?)$
+

+Again, this works in Perl, but not in PCRE, and for the same reason. When a
+deeper recursion has matched a single character, it cannot be entered again in
+order to match an empty string. The solution is to separate the two cases, and
+write out the odd and even cases as alternatives at the higher level:
+
+  ^(?:((.)(?1)\2|)|((.)(?3)\4|.))
+

+If you want to match typical palindromic phrases, the pattern has to ignore all
+non-word characters, which can be done like this:
+
+  ^\W*+(?:((.)\W*+(?1)\W*+\2|)|((.)\W*+(?3)\W*+\4|\W*+.\W*+))\W*+$
+

+If run with the PCRE_CASELESS option, this pattern matches phrases such as "A
+man, a plan, a canal: Panama!" and it works well in both PCRE and Perl. Note
+the use of the possessive quantifier *+ to avoid backtracking into sequences of
+non-word characters. Without this, PCRE takes a great deal longer (ten times or
+more) to match typical phrases, and Perl takes so long that you think it has
+gone into a loop.
+

+

+WARNING: The palindrome-matching patterns above work only if the subject
+string does not start with a palindrome that is shorter than the entire string.
+For example, although "abcba" is correctly matched, if the subject is "ababa",
+PCRE finds the palindrome "aba" at the start, then fails at top level because
+the end of the string does not follow. Once again, it cannot jump back into the
+recursion to try other alternatives, so the entire match fails.
+

+
SUBPATTERNS AS SUBROUTINES

+

+If the syntax for a recursive subpattern reference (either by number or by
+name) is used outside the parentheses to which it refers, it operates like a
+subroutine in a programming language. The "called" subpattern may be defined
+before or after the reference. A numbered reference can be absolute or
+relative, as in these examples:
+
+  (...(absolute)...)...(?2)...
+  (...(relative)...)...(?-1)...
+  (...(?+1)...(relative)...
+

+An earlier example pointed out that the pattern
+
+  (sens|respons)e and \1ibility
+

+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If instead the pattern
+
+  (sens|respons)e and (?1)ibility
+

+is used, it does match "sense and responsibility" as well as the other two
+strings. Another example is given in the discussion of DEFINE above.
+

+

+Like recursive subpatterns, a subroutine call is always treated as an atomic
+group. That is, once it has matched some of the subject string, it is never
+re-entered, even if it contains untried alternatives and there is a subsequent
+matching failure. Any capturing parentheses that are set during the subroutine
+call revert to their previous values afterwards.
+

+

+When a subpattern is used as a subroutine, processing options such as
+case-independence are fixed when the subpattern is defined. They cannot be
+changed for different calls. For example, consider this pattern:
+
+  (abc)(?i:(?-1))
+

+It matches "abcabc". It does not match "abcABC" because the change of
+processing option does not affect the called subpattern.
+

+
ONIGURUMA SUBROUTINE SYNTAX

+

+For compatibility with Oniguruma, the non-Perl syntax \g followed by a name or
+a number enclosed either in angle brackets or single quotes, is an alternative
+syntax for referencing a subpattern as a subroutine, possibly recursively. Here
+are two of the examples used above, rewritten using this syntax:
+
+  (?<pn> \( ( (?>[^()]+) | \g<pn> )* \) )
+  (sens|respons)e and \g'1'ibility
+

+PCRE supports an extension to Oniguruma: if a number is preceded by a
+plus or a minus sign it is taken as a relative reference. For example:
+
+  (abc)(?i:\g<-1>)
+

+Note that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are not
+synonymous. The former is a back reference; the latter is a subroutine call.
+

+
CALLOUTS

+

+Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl
+code to be obeyed in the middle of matching a regular expression. This makes it
+possible, amongst other things, to extract different substrings that match the
+same pair of parentheses when there is a repetition.
+

+

+PCRE provides a similar feature, but of course it cannot obey arbitrary Perl
+code. The feature is called "callout". The caller of PCRE provides an external
+function by putting its entry point in the global variable pcre_callout.
+By default, this variable contains NULL, which disables all calling out.
+

+

+Within a regular expression, (?C) indicates the points at which the external
+function is to be called. If you want to identify different callout points, you
+can put a number less than 256 after the letter C. The default value is zero.
+For example, this pattern has two callout points:
+
+  (?C1)abc(?C2)def
+

+If the PCRE_AUTO_CALLOUT flag is passed to pcre_compile(), callouts are
+automatically installed before each item in the pattern. They are all numbered
+255.
+

+

+During matching, when PCRE reaches a callout point (and pcre_callout is
+set), the external function is called. It is provided with the number of the
+callout, the position in the pattern, and, optionally, one item of data
+originally supplied by the caller of pcre_exec(). The callout function
+may cause matching to proceed, to backtrack, or to fail altogether. A complete
+description of the interface to the callout function is given in the
+pcrecallout
+documentation.
+

+
BACKTRACKING CONTROL

+

+Perl 5.10 introduced a number of "Special Backtracking Control Verbs", which
+are described in the Perl documentation as "experimental and subject to change
+or removal in a future version of Perl". It goes on to say: "Their usage in
+production code should be noted to avoid problems during upgrades." The same
+remarks apply to the PCRE features described in this section.
+

+

+Since these verbs are specifically related to backtracking, most of them can be
+used only when the pattern is to be matched using pcre_exec(), which uses
+a backtracking algorithm. With the exception of (*FAIL), which behaves like a
+failing negative assertion, they cause an error if encountered by
+pcre_dfa_exec().
+

+

+If any of these verbs are used in an assertion or subroutine subpattern
+(including recursive subpatterns), their effect is confined to that subpattern;
+it does not extend to the surrounding pattern. Note that such subpatterns are
+processed as anchored at the point where they are tested.
+

+

+The new verbs make use of what was previously invalid syntax: an opening
+parenthesis followed by an asterisk. In Perl, they are generally of the form
+(*VERB:ARG) but PCRE does not support the use of arguments, so its general
+form is just (*VERB). Any number of these verbs may occur in a pattern. There
+are two kinds:
+

+

+Verbs that act immediately
+

+

+The following verbs act as soon as they are encountered:
+
+   (*ACCEPT)
+

+This verb causes the match to end successfully, skipping the remainder of the
+pattern. When inside a recursion, only the innermost pattern is ended
+immediately. If (*ACCEPT) is inside capturing parentheses, the data so far is
+captured. (This feature was added to PCRE at release 8.00.) For example:
+
+  A((?:A|B(*ACCEPT)|C)D)
+

+This matches "AB", "AAD", or "ACD"; when it matches "AB", "B" is captured by
+the outer parentheses.
+
+  (*FAIL) or (*F)
+

+This verb causes the match to fail, forcing backtracking to occur. It is
+equivalent to (?!) but easier to read. The Perl documentation notes that it is
+probably useful only when combined with (?{}) or (??{}). Those are, of course,
+Perl features that are not present in PCRE. The nearest equivalent is the
+callout feature, as for example in this pattern:
+
+  a+(?C)(*FAIL)
+

+A match with the string "aaaa" always fails, but the callout is taken before
+each backtrack happens (in this example, 10 times).
+

+

+Verbs that act after backtracking
+

+

+The following verbs do nothing when they are encountered. Matching continues
+with what follows, but if there is no subsequent match, a failure is forced.
+The verbs differ in exactly what kind of failure occurs.
+
+  (*COMMIT)
+

+This verb causes the whole match to fail outright if the rest of the pattern
+does not match. Even if the pattern is unanchored, no further attempts to find
+a match by advancing the starting point take place. Once (*COMMIT) has been
+passed, pcre_exec() is committed to finding a match at the current
+starting point, or not at all. For example:
+
+  a+(*COMMIT)b
+

+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish."
+
+  (*PRUNE)
+

+This verb causes the match to fail at the current position if the rest of the
+pattern does not match. If the pattern is unanchored, the normal "bumpalong"
+advance to the next starting character then happens. Backtracking can occur as
+usual to the left of (*PRUNE), or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE).
+In simple cases, the use of (*PRUNE) is just an alternative to an atomic
+group or possessive quantifier, but there are some uses of (*PRUNE) that cannot
+be expressed in any other way.
+
+  (*SKIP)
+

+This verb is like (*PRUNE), except that if the pattern is unanchored, the
+"bumpalong" advance is not to the next character, but to the position in the
+subject where (*SKIP) was encountered. (*SKIP) signifies that whatever text
+was matched leading up to it cannot be part of a successful match. Consider:
+
+  a+(*SKIP)b
+

+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifer does not have the same
+effect as this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+
+  (*THEN)
+

+This verb causes a skip to the next alternation if the rest of the pattern does
+not match. That is, it cancels pending backtracking, but only within the
+current alternation. Its name comes from the observation that it can be used
+for a pattern-based if-then-else block:
+
+  ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+

+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If (*THEN)
+is used outside of any alternation, it acts exactly like (*PRUNE).

+

+PCRE PERFORMANCE
+

+

+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+

+

+MEMORY USAGE
+

+

+Patterns are compiled by PCRE into a reasonably efficient byte code, so that
+most simple patterns do not use much memory. However, there is one case where
+memory usage can be unexpectedly large. When a parenthesized subpattern has a
+quantifier with a minimum greater than 1 and/or a limited maximum, the whole
+subpattern is repeated in the compiled code. For example, the pattern
+
+  (abc|def){2,4}
+

+is compiled as if it were
+
+  (abc|def)(abc|def)((abc|def)(abc|def)?)?
+

+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+

+

+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+
+  ((ab){1,1000}c){1,3}
+

+uses 51K bytes when compiled. When PCRE is compiled with its default internal
+pointer size of two bytes, the size limit on a compiled pattern is 64K, and
+this is reached with the above pattern if the outer repetition is increased
+from 3 to 4. PCRE can be compiled to use larger internal pointers and thus
+handle larger compiled patterns, but it is better to try to rewrite your
+pattern to use less memory if you can.
+

+

+One way of reducing the memory usage for such patterns is to make use of PCRE's
+"subroutine"
+facility. Re-writing the above pattern as
+
+  ((ab)(?2){0,999}c)(?1){0,2}
+

+reduces the memory requirements to 18K, and indeed it remains under 20K even
+with the outer repetition increased to 100. However, this pattern is not
+exactly equivalent, because the "subroutine" calls are treated as
+atomic groups
+into which there can be no backtracking if there is a subsequent matching
+failure. Therefore, PCRE cannot do this kind of rewriting automatically.
+Furthermore, there is a noticeable loss of speed when executing the modified
+pattern. Nevertheless, if the atomic grouping is not a problem and the loss of
+speed is acceptable, this kind of rewriting will allow you to process patterns
+that PCRE cannot otherwise handle.
+

+

+PROCESSING TIME
+

+

+Certain items in regular expression patterns are processed more efficiently
+than others. It is more efficient to use a character class like [aeiou] than a
+set of single-character alternatives such as (a|e|i|o|u). In general, the
+simplest construction that provides the required behaviour is usually the most
+efficient. Jeffrey Friedl's book contains a lot of useful general discussion
+about optimizing regular expressions for efficient performance. This document
+contains a few observations about PCRE.
+

+

+Using Unicode character properties (the \p, \P, and \X escapes) is slow,
+because PCRE has to scan a structure that contains data for over fifteen
+thousand characters whenever it needs a character's property. If you can find
+an alternative pattern that does not use character properties, it will probably
+be faster.
+

+

+When a pattern begins with .* not in parentheses, or in parentheses that are
+not the subject of a backreference, and the PCRE_DOTALL option is set, the
+pattern is implicitly anchored by PCRE, since it can match only at the start of
+a subject string. However, if PCRE_DOTALL is not set, PCRE cannot make this
+optimization, because the . metacharacter does not then match a newline, and if
+the subject string contains newlines, the pattern may match from the character
+immediately following one of them instead of from the very start. For example,
+the pattern
+
+  .*second
+

+matches the subject "first\nand second" (where \n stands for a newline
+character), with the match starting at the seventh character. In order to do
+this, PCRE has to retry the match starting after every newline in the subject.
+

+

+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE_DOTALL, or starting
+the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE
+from having to scan along the subject looking for a newline to restart at.
+

+

+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+
+  ^(a+)*
+

+This can match "aaaa" in 16 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0 or 4, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE has in principle to try every possible
+variation, and this can take an extremely long time, even for relatively short
+strings.
+

+

+An optimization catches some of the more simple cases such as
+
+  (a+)*b
+

+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+
+  (a+)*\d
+

+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+

+

+In many cases, the solution to this kind of performance issue is to use an
+atomic group or a possessive quantifier.

DESCRIPTION

+

+This set of functions provides a POSIX-style API to the PCRE regular expression
+package. See the
+pcreapi
+documentation for a description of PCRE's native API, which contains much
+additional functionality.
+

+

+The functions described here are just wrapper functions that ultimately call
+the PCRE native API. Their prototypes are defined in the pcreposix.h
+header file, and on Unix systems the library itself is called
+pcreposix.a, so can be accessed by adding -lpcreposix to the
+command for linking an application that uses them. Because the POSIX functions
+call the native ones, it is also necessary to add -lpcre.
+

+

+I have implemented only those POSIX option bits that can be reasonably mapped
+to PCRE native options. In addition, the option REG_EXTENDED is defined with
+the value zero. This has no effect, but since programs that are written to the
+POSIX interface often use it, this makes it easier to slot in PCRE as a
+replacement library. Other POSIX options are not even defined.
+

+

+There are also some other options that are not defined by POSIX. These have
+been added at the request of users who want to make use of certain
+PCRE-specific features via the POSIX calling interface.
+

+

+When PCRE is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE options, as
+described below. "POSIX-like in style" means that the API approximates to the
+POSIX definition; it is not fully POSIX-compatible, and in multi-byte encoding
+domains it is probably even less compatible.
+

+

+The header for these functions is supplied as pcreposix.h to avoid any
+potential clash with other POSIX libraries. It can, of course, be renamed or
+aliased as regex.h, which is the "correct" name. It provides two
+structure types, regex_t for compiled internal forms, and
+regmatch_t for returning captured substrings. It also defines some
+constants whose names start with "REG_"; these are used for setting options and
+identifying error codes.
+

+

+

+
COMPILING A PATTERN

+

+The function regcomp() is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument pattern. The preg argument is a pointer
+to a regex_t structure that is used as a base for storing information
+about the compiled regular expression.
+

+

+The argument cflags is either zero, or contains one or more of the bits
+defined by the following macros:
+
+  REG_DOTALL
+

+The PCRE_DOTALL option is set when the regular expression is passed for
+compilation to the native function. Note that REG_DOTALL is not part of the
+POSIX standard.
+
+  REG_ICASE
+

+The PCRE_CASELESS option is set when the regular expression is passed for
+compilation to the native function.
+
+  REG_NEWLINE
+

+The PCRE_MULTILINE option is set when the regular expression is passed for
+compilation to the native function. Note that this does not mimic the
+defined POSIX behaviour for REG_NEWLINE (see the following section).
+
+  REG_NOSUB
+

+The PCRE_NO_AUTO_CAPTURE option is set when the regular expression is passed
+for compilation to the native function. In addition, when a pattern that is
+compiled with this flag is passed to regexec() for matching, the
+nmatch and pmatch arguments are ignored, and no captured strings
+are returned.
+
+  REG_UNGREEDY
+

+The PCRE_UNGREEDY option is set when the regular expression is passed for
+compilation to the native function. Note that REG_UNGREEDY is not part of the
+POSIX standard.
+
+  REG_UTF8
+

+The PCRE_UTF8 option is set when the regular expression is passed for
+compilation to the native function. This causes the pattern itself and all data
+strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF8
+is not part of the POSIX standard.
+

+

+In the absence of these flags, no options are passed to the native function.
+This means the the regex is compiled with PCRE default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE_MULTILINE has only
+some of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by . (they are not) or by a negative class such as [^a]
+(they are).
+

+

+The yield of regcomp() is zero on success, and non-zero otherwise. The
+preg structure is filled in on success, and one member of the structure
+is public: re_nsub contains the number of capturing subpatterns in
+the regular expression. Various error codes are defined in the header file.
+

+

+NOTE: If the yield of regcomp() is non-zero, you must not attempt to
+use the contents of the preg structure. If, for example, you pass it to
+regexec(), the result is undefined and your program is likely to crash.
+

+
MATCHING NEWLINE CHARACTERS

+

+This area is not simple, because POSIX and Perl take different views of things.
+It is not possible to get PCRE to obey POSIX semantics, but then PCRE was never
+intended to be a POSIX engine. The following table lists the different
+possibilities for matching newline characters in PCRE:
+
+                          Default   Change with
+
+  . matches newline          no     PCRE_DOTALL
+  newline matches [^a]       yes    not changeable
+  $ matches \n at end        yes    PCRE_DOLLARENDONLY
+  $ matches \n in middle     no     PCRE_MULTILINE
+  ^ matches \n in middle     no     PCRE_MULTILINE
+

+This is the equivalent table for POSIX:
+
+                          Default   Change with
+
+  . matches newline          yes    REG_NEWLINE
+  newline matches [^a]       yes    REG_NEWLINE
+  $ matches \n at end        no     REG_NEWLINE
+  $ matches \n in middle     no     REG_NEWLINE
+  ^ matches \n in middle     no     REG_NEWLINE
+

+PCRE's behaviour is the same as Perl's, except that there is no equivalent for
+PCRE_DOLLAR_ENDONLY in Perl. In both PCRE and Perl, there is no way to stop
+newline from matching [^a].
+

+

+The default POSIX newline handling can be obtained by setting PCRE_DOTALL and
+PCRE_DOLLAR_ENDONLY, but there is no way to make PCRE behave exactly as for the
+REG_NEWLINE action.
+

+
MATCHING A PATTERN

+

+The function regexec() is called to match a compiled pattern preg
+against a given string, which is by default terminated by a zero byte
+(but see REG_STARTEND below), subject to the options in eflags. These can
+be:
+
+  REG_NOTBOL
+

+The PCRE_NOTBOL option is set when calling the underlying PCRE matching
+function.
+
+  REG_NOTEMPTY
+

+The PCRE_NOTEMPTY option is set when calling the underlying PCRE matching
+function. Note that REG_NOTEMPTY is not part of the POSIX standard. However,
+setting this option can give more POSIX-like behaviour in some situations.
+
+  REG_NOTEOL
+

+The PCRE_NOTEOL option is set when calling the underlying PCRE matching
+function.
+
+  REG_STARTEND
+

+The string is considered to start at string + pmatch[0].rm_so and
+to have a terminating NUL located at string + pmatch[0].rm_eo
+(there need not actually be a NUL at that location), regardless of the value of
+nmatch. This is a BSD extension, compatible with but not specified by
+IEEE Standard 1003.2 (POSIX.2), and should be used with caution in software
+intended to be portable to other systems. Note that a non-zero rm_so does
+not imply REG_NOTBOL; REG_STARTEND affects only the location of the string, not
+how it is matched.
+

+

+If the pattern was compiled with the REG_NOSUB flag, no data about any matched
+strings is returned. The nmatch and pmatch arguments of
+regexec() are ignored.
+

+

+If the value of nmatch is zero, or if the value pmatch is NULL,
+no data about any matched strings is returned.
+

+

+Otherwise,the portion of the string that was matched, and also any captured
+substrings, are returned via the pmatch argument, which points to an
+array of nmatch structures of type regmatch_t, containing the
+members rm_so and rm_eo. These contain the offset to the first
+character of each substring and the offset to the first character after the end
+of each substring, respectively. The 0th element of the vector relates to the
+entire portion of string that was matched; subsequent elements relate to
+the capturing subpatterns of the regular expression. Unused entries in the
+array have both structure members set to -1.
+

+

+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+

+
ERROR MESSAGES

+

+The regerror() function maps a non-zero errorcode from either
+regcomp() or regexec() to a printable message. If preg is not
+NULL, the error should have arisen from the use of that structure. A message
+terminated by a binary zero is placed in errbuf. The length of the
+message, including the zero, is limited to errbuf_size. The yield of the
+function is the size of buffer needed to hold the whole message.
+

+
MEMORY USAGE

+

+Compiling a regular expression causes memory to be allocated and associated
+with the preg structure. The function regfree() frees all such
+memory, after which preg may no longer be used as a compiled expression.

+
SAVING AND RE-USING PRECOMPILED PCRE PATTERNS

+

+If you are running an application that uses a large number of regular
+expression patterns, it may be useful to store them in a precompiled form
+instead of having to compile them every time the application is run.
+If you are not using any private character tables (see the
+pcre_maketables()
+documentation), this is relatively straightforward. If you are using private
+tables, it is a little bit more complicated.
+

+

+If you save compiled patterns to a file, you can copy them to a different host
+and run them there. This works even if the new host has the opposite endianness
+to the one on which the patterns were compiled. There may be a small
+performance penalty, but it should be insignificant. However, compiling regular
+expressions with one version of PCRE for use with a different version is not
+guaranteed to work and may cause crashes.
+

+
SAVING A COMPILED PATTERN

+

+The value returned by pcre_compile() points to a single block of memory
+that holds the compiled pattern and associated data. You can find the length of
+this block in bytes by calling pcre_fullinfo() with an argument of
+PCRE_INFO_SIZE. You can then save the data in any appropriate manner. Here is
+sample code that compiles a pattern and writes it to a file. It assumes that
+the variable fd refers to a file that is open for output:
+
+  int erroroffset, rc, size;
+  char *error;
+  pcre *re;
+
+  re = pcre_compile("my pattern", 0, &error, &erroroffset, NULL);
+  if (re == NULL) { ... handle errors ... }
+  rc = pcre_fullinfo(re, NULL, PCRE_INFO_SIZE, &size);
+  if (rc < 0) { ... handle errors ... }
+  rc = fwrite(re, 1, size, fd);
+  if (rc != size) { ... handle errors ... }
+

+In this example, the bytes that comprise the compiled pattern are copied
+exactly. Note that this is binary data that may contain any of the 256 possible
+byte values. On systems that make a distinction between binary and non-binary
+data, be sure that the file is opened for binary output.
+

+

+If you want to write more than one pattern to a file, you will have to devise a
+way of separating them. For binary data, preceding each pattern with its length
+is probably the most straightforward approach. Another possibility is to write
+out the data in hexadecimal instead of binary, one pattern to a line.
+

+

+Saving compiled patterns in a file is only one possible way of storing them for
+later use. They could equally well be saved in a database, or in the memory of
+some daemon process that passes them via sockets to the processes that want
+them.
+

+

+If the pattern has been studied, it is also possible to save the study data in
+a similar way to the compiled pattern itself. When studying generates
+additional information, pcre_study() returns a pointer to a
+pcre_extra data block. Its format is defined in the
+section on matching a pattern
+in the
+pcreapi
+documentation. The study_data field points to the binary study data, and
+this is what you must save (not the pcre_extra block itself). The length
+of the study data can be obtained by calling pcre_fullinfo() with an
+argument of PCRE_INFO_STUDYSIZE. Remember to check that pcre_study() did
+return a non-NULL value before trying to save the study data.
+

+
RE-USING A PRECOMPILED PATTERN

+

+Re-using a precompiled pattern is straightforward. Having reloaded it into main
+memory, you pass its pointer to pcre_exec() or pcre_dfa_exec() in
+the usual way. This should work even on another host, and even if that host has
+the opposite endianness to the one where the pattern was compiled.
+

+

+However, if you passed a pointer to custom character tables when the pattern
+was compiled (the tableptr argument of pcre_compile()), you must
+now pass a similar pointer to pcre_exec() or pcre_dfa_exec(),
+because the value saved with the compiled pattern will obviously be nonsense. A
+field in a pcre_extra() block is used to pass this data, as described in
+the
+section on matching a pattern
+in the
+pcreapi
+documentation.
+

+

+If you did not provide custom character tables when the pattern was compiled,
+the pointer in the compiled pattern is NULL, which causes pcre_exec() to
+use PCRE's internal tables. Thus, you do not need to take any special action at
+run time in this case.
+

+

+If you saved study data with the compiled pattern, you need to create your own
+pcre_extra data block and set the study_data field to point to the
+reloaded study data. You must also set the PCRE_EXTRA_STUDY_DATA bit in the
+flags field to indicate that study data is present. Then pass the
+pcre_extra block to pcre_exec() or pcre_dfa_exec() in the
+usual way.
+

+
COMPATIBILITY WITH DIFFERENT PCRE RELEASES

+

+In general, it is safest to recompile all saved patterns when you update to a
+new PCRE release, though not all updates actually require this. Recompiling is
+definitely needed for release 7.2.

+PCRE SAMPLE PROGRAM
+

+

+A simple, complete demonstration program, to get you started with using PCRE,
+is supplied in the file pcredemo.c in the PCRE distribution. A listing of
+this program is given in the
+pcredemo
+documentation. If you do not have a copy of the PCRE distribution, you can save
+this listing to re-create pcredemo.c.
+

+

+The program compiles the regular expression that is its first argument, and
+matches it against the subject string in its second argument. No PCRE options
+are set, and default character tables are used. If matching succeeds, the
+program outputs the portion of the subject that matched, together with the
+contents of any captured substrings.
+

+

+If the -g option is given on the command line, the program then goes on to
+check for further matches of the same regular expression in the same subject
+string. The logic is a little bit tricky because of the possibility of matching
+an empty string. Comments in the code explain what is going on.
+

+

+If PCRE is installed in the standard include and library directories for your
+operating system, you should be able to compile the demonstration program using
+this command:
+
+  gcc -o pcredemo pcredemo.c -lpcre
+

+If PCRE is installed elsewhere, you may need to add additional options to the
+command line. For example, on a Unix-like system that has PCRE installed in
+/usr/local, you can compile the demonstration program using a command
+like this:
+
+  gcc -o pcredemo -I/usr/local/include pcredemo.c -L/usr/local/lib -lpcre
+

+Once you have compiled the demonstration program, you can run simple tests like
+this:
+
+  ./pcredemo 'cat|dog' 'the cat sat on the mat'
+  ./pcredemo -g 'cat|dog' 'the dog sat on the cat'
+

+Note that there is a much more comprehensive test program, called
+pcretest,
+which supports many more facilities for testing regular expressions and the
+PCRE library. The
+pcredemo
+program is provided as a simple coding example.
+

+

+When you try to run
+pcredemo
+when PCRE is not installed in the standard library directory, you may get an
+error like this on some operating systems (e.g. Solaris):
+
+  ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory
+

+This is caused by the way shared library support works on those systems. You
+need to add
+
+  -R/usr/local/lib
+

+(for example) to the compile command to get round this problem.

+PCRE DISCUSSION OF STACK USAGE
+

+

+When you call pcre_exec(), it makes use of an internal function called
+match(). This calls itself recursively at branch points in the pattern,
+in order to remember the state of the match so that it can back up and try a
+different alternative if the first one fails. As matching proceeds deeper and
+deeper into the tree of possibilities, the recursion depth increases.
+

+

+Not all calls of match() increase the recursion depth; for an item such
+as a* it may be called several times at the same level, after matching
+different numbers of a's. Furthermore, in a number of cases where the result of
+the recursive call would immediately be passed back as the result of the
+current call (a "tail recursion"), the function is just restarted instead.
+

+

+The pcre_dfa_exec() function operates in an entirely different way, and
+hardly uses recursion at all. The limit on its complexity is the amount of
+workspace it is given. The comments that follow do NOT apply to
+pcre_dfa_exec(); they are relevant only for pcre_exec().
+

+

+You can set limits on the number of times that match() is called, both in
+total and recursively. If the limit is exceeded, an error occurs. For details,
+see the
+section on extra data for pcre_exec()
+in the
+pcreapi
+documentation.
+

+

+Each time that match() is actually called recursively, it uses memory
+from the process stack. For certain kinds of pattern and data, very large
+amounts of stack may be needed, despite the recognition of "tail recursion".
+You can often reduce the amount of recursion, and therefore the amount of stack
+used, by modifying the pattern that is being matched. Consider, for example,
+this pattern:
+
+  ([^<]|<(?!inet))+
+

+It matches from wherever it starts until it encounters "<inet" or the end of
+the data, and is the kind of pattern that might be used when processing an XML
+file. Each iteration of the outer parentheses matches either one character that
+is not "<" or a "<" that is not followed by "inet". However, each time a
+parenthesis is processed, a recursion occurs, so this formulation uses a stack
+frame for each matched character. For a long string, a lot of stack is
+required. Consider now this rewritten pattern, which matches exactly the same
+strings:
+
+  ([^<]++|<(?!inet))+
+

+This uses very much less stack, because runs of characters that do not contain
+"<" are "swallowed" in one item inside the parentheses. Recursion happens only
+when a "<" character that is not followed by "inet" is encountered (and we
+assume this is relatively rare). A possessive quantifier is used to stop any
+backtracking into the runs of non-"<" characters, but that is not related to
+stack usage.
+

+

+This example shows that one way of avoiding stack problems when matching long
+subject strings is to write repeated parenthesized subpatterns to match more
+than one character whenever possible.
+

+

+Compiling PCRE to use heap instead of stack
+

+

+In environments where stack memory is constrained, you might want to compile
+PCRE to use heap memory instead of stack for remembering back-up points. This
+makes it run a lot more slowly, however. Details of how to do this are given in
+the
+pcrebuild
+documentation. When built in this way, instead of using the stack, PCRE obtains
+and frees memory by calling the functions that are pointed to by the
+pcre_stack_malloc and pcre_stack_free variables. By default, these
+point to malloc() and free(), but you can replace the pointers to
+cause PCRE to use your own functions. Since the block sizes are always the
+same, and are always freed in reverse order, it may be possible to implement
+customized memory handlers that are more efficient than the standard functions.
+

+

+Limiting PCRE's stack usage
+

+

+PCRE has an internal counter that can be used to limit the depth of recursion,
+and thus cause pcre_exec() to give an error code before it runs out of
+stack. By default, the limit is very large, and unlikely ever to operate. It
+can be changed when PCRE is built, and it can also be set when
+pcre_exec() is called. For details of these interfaces, see the
+pcrebuild
+and
+pcreapi
+documentation.
+

+

+As a very rough rule of thumb, you should reckon on about 500 bytes per
+recursion. Thus, if you want to limit your stack usage to 8Mb, you
+should set the limit at 16000 recursions. A 64Mb stack, on the other hand, can
+support around 128000 recursions. The pcretest test program has a command
+line option (-S) that can be used to increase the size of its stack.

+Changing stack size in Unix-like systems
+

+

+In Unix-like environments, there is not often a problem with the stack unless
+very long strings are involved, though the default limit on stack size varies
+from system to system. Values from 8Mb to 64Mb are common. You can find your
+default limit by running the command:
+
+  ulimit -s
+

+Unfortunately, the effect of running out of stack is often SIGSEGV, though
+sometimes a more explicit error message is given. You can normally increase the
+limit on stack size by code such as this:
+
+  struct rlimit rlim;
+  getrlimit(RLIMIT_STACK, &rlim);
+  rlim.rlim_cur = 100*1024*1024;
+  setrlimit(RLIMIT_STACK, &rlim);
+

+This reads the current limits (soft and hard) using getrlimit(), then
+attempts to increase the soft limit to 100Mb using setrlimit(). You must
+do this before calling pcre_exec().
+

+

+Changing stack size in Mac OS X
+

+

+Using setrlimit(), as described above, should also work on Mac OS X. It
+is also possible to set a stack size when linking a program. There is a
+discussion about stack sizes in Mac OS X at this web site:
+http://developer.apple.com/qa/qa2005/qa1419.html.

PCRE REGULAR EXPRESSION SYNTAX SUMMARY

+

+The full syntax and semantics of the regular expressions that are supported by
+PCRE are described in the
+pcrepattern
+documentation. This document contains just a quick-reference summary of the
+syntax.
+

+
QUOTING

+

+
+  \x         where x is non-alphanumeric is a literal x
+  \Q...\E    treat enclosed characters as literal
+

+

+
CHARACTERS

+

+
+  \a         alarm, that is, the BEL character (hex 07)
+  \cx        "control-x", where x is any character
+  \e         escape (hex 1B)
+  \f         formfeed (hex 0C)
+  \n         newline (hex 0A)
+  \r         carriage return (hex 0D)
+  \t         tab (hex 09)
+  \ddd       character with octal code ddd, or backreference
+  \xhh       character with hex code hh
+  \x{hhh..}  character with hex code hhh..
+

+

+
CHARACTER TYPES

+

+
+  .          any character except newline;
+               in dotall mode, any character whatsoever
+  \C         one byte, even in UTF-8 mode (best avoided)
+  \d         a decimal digit
+  \D         a character that is not a decimal digit
+  \h         a horizontal whitespace character
+  \H         a character that is not a horizontal whitespace character
+  \p{xx}     a character with the xx property
+  \P{xx}     a character without the xx property
+  \R         a newline sequence
+  \s         a whitespace character
+  \S         a character that is not a whitespace character
+  \v         a vertical whitespace character
+  \V         a character that is not a vertical whitespace character
+  \w         a "word" character
+  \W         a "non-word" character
+  \X         an extended Unicode sequence
+

+In PCRE, \d, \D, \s, \S, \w, and \W recognize only ASCII characters.

SYNOPSIS

+

+pcretest [options] [source] [destination]
+

+

+pcretest was written as a test program for the PCRE regular expression
+library itself, but it can also be used for experimenting with regular
+expressions. This document describes the features of the test program; for
+details of the regular expressions themselves, see the
+pcrepattern
+documentation. For details of the PCRE library function calls and their
+options, see the
+pcreapi
+documentation.
+

+
OPTIONS

+

+-b
+Behave as if each regex has the /B (show bytecode) modifier; the internal
+form is output after compilation.
+

+

+-C
+Output the version number of the PCRE library, and all available information
+about the optional features that are included, and then exit.
+

+

+-d
+Behave as if each regex has the /D (debug) modifier; the internal
+form and information about the compiled pattern is output after compilation;
+-d is equivalent to -b -i.
+

+

+-dfa
+Behave as if each data line contains the \D escape sequence; this causes the
+alternative matching function, pcre_dfa_exec(), to be used instead of the
+standard pcre_exec() function (more detail is given below).
+

+

+-help
+Output a brief summary these options and then exit.
+

+

+-i
+Behave as if each regex has the /I modifier; information about the
+compiled pattern is given after compilation.
+

+

+-M
+Behave as if each data line contains the \M escape sequence; this causes
+PCRE to discover the minimum MATCH_LIMIT and MATCH_LIMIT_RECURSION settings by
+calling pcre_exec() repeatedly with different limits.
+

+

+-m
+Output the size of each compiled pattern after it has been compiled. This is
+equivalent to adding /M to each regular expression. For compatibility
+with earlier versions of pcretest, -s is a synonym for -m.
+

+

+-o osize
+Set the number of elements in the output vector that is used when calling
+pcre_exec() or pcre_dfa_exec() to be osize. The default value
+is 45, which is enough for 14 capturing subexpressions for pcre_exec() or
+22 different matches for pcre_dfa_exec(). The vector size can be
+changed for individual matching calls by including \O in the data line (see
+below).
+

+

+-p
+Behave as if each regex has the /P modifier; the POSIX wrapper API is
+used to call PCRE. None of the other options has any effect when -p is
+set.
+

+

+-q
+Do not output the version number of pcretest at the start of execution.
+

+

+-S size
+On Unix-like systems, set the size of the runtime stack to size
+megabytes.
+

+

+-t
+Run each compile, study, and match many times with a timer, and output
+resulting time per compile or match (in milliseconds). Do not set -m with
+-t, because you will then get the size output a zillion times, and the
+timing will be distorted. You can control the number of iterations that are
+used for timing by following -t with a number (as a separate item on the
+command line). For example, "-t 1000" would iterate 1000 times. The default is
+to iterate 500000 times.
+

+

+-tm
+This is like -t except that it times only the matching phase, not the
+compile or study phases.
+

+
DESCRIPTION

+

+If pcretest is given two filename arguments, it reads from the first and
+writes to the second. If it is given only one filename argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout, and prompts for each line of input, using "re>" to prompt for regular
+expressions, and "data>" to prompt for data lines.
+

+

+When pcretest is built, a configuration option can specify that it should
+be linked with the libreadline library. When this is done, if the input
+is from a terminal, it is read using the readline() function. This
+provides line-editing and history facilities. The output from the -help
+option states whether or not readline() will be used.
+

+

+The program handles any number of sets of input on a single input file. Each
+set starts with a regular expression, and continues with any number of data
+lines to be matched against the pattern.
+

+

+Each data line is matched separately and independently. If you want to do
+multi-line matches, you have to use the \n escape sequence (or \r or \r\n,
+etc., depending on the newline setting) in a single line of input to encode the
+newline sequences. There is no limit on the length of data lines; the input
+buffer is automatically extended if it is too small.
+

+

+An empty line signals the end of the data lines, at which point a new regular
+expression is read. The regular expressions are given enclosed in any
+non-alphanumeric delimiters other than backslash, for example:
+
+  /(a|bc)x+yz/
+

+White space before the initial delimiter is ignored. A regular expression may
+be continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter within the pattern
+by escaping it, for example
+
+  /abc\/def/
+

+If you do so, the escape and the delimiter form part of the pattern, but since
+delimiters are always non-alphanumeric, this does not affect its interpretation.
+If the terminating delimiter is immediately followed by a backslash, for
+example,
+
+  /abc/\
+

+then a backslash is added to the end of the pattern. This is done to provide a
+way of testing the error condition that arises if a pattern finishes with a
+backslash, because
+
+  /abc\/
+

+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcretest to read the next line as a continuation of the regular expression.
+

+
PATTERN MODIFIERS

+

+A pattern may be followed by any number of modifiers, which are mostly single
+characters. Following Perl usage, these are referred to below as, for example,
+"the /i modifier", even though the delimiter of the pattern need not
+always be a slash, and no slash is used when writing modifiers. Whitespace may
+appear between the final pattern delimiter and the first modifier, and between
+the modifiers themselves.
+

+

+The /i, /m, /s, and /x modifiers set the PCRE_CASELESS,
+PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options, respectively, when
+pcre_compile() is called. These four modifier letters have the same
+effect as they do in Perl. For example:
+
+  /caseless/i
+

+The following table shows additional modifiers for setting PCRE options that do
+not correspond to anything in Perl:
+
+  /A              PCRE_ANCHORED
+  /C              PCRE_AUTO_CALLOUT
+  /E              PCRE_DOLLAR_ENDONLY
+  /f              PCRE_FIRSTLINE
+  /J              PCRE_DUPNAMES
+  /N              PCRE_NO_AUTO_CAPTURE
+  /U              PCRE_UNGREEDY
+  /X              PCRE_EXTRA

+Those specifying line ending sequences are literal strings as shown, but the
+letters can be in either case. This example sets multiline matching with CRLF
+as the line ending sequence:
+
+  /^abc/m<crlf>
+

+Details of the meanings of these PCRE options are given in the
+pcreapi
+documentation.
+

+

+Finding all matches in a string
+

+

+Searching for all possible matches within each subject string can be requested
+by the /g or /G modifier. After finding a match, PCRE is called
+again to search the remainder of the subject string. The difference between
+/g and /G is that the former uses the startoffset argument to
+pcre_exec() to start searching at a new point within the entire string
+(which is in effect what Perl does), whereas the latter passes over a shortened
+substring. This makes a difference to the matching process if the pattern
+begins with a lookbehind assertion (including \b or \B).
+

+

+If any call to pcre_exec() in a /g or /G sequence matches an
+empty string, the next call is done with the PCRE_NOTEMPTY_ATSTART and
+PCRE_ANCHORED flags set in order to search for another, non-empty, match at the
+same point. If this second match fails, the start offset is advanced by one
+character, and the normal match is retried. This imitates the way Perl handles
+such cases when using the /g modifier or the split() function.
+

+

+Other modifiers
+

+

+There are yet more modifiers for controlling the way pcretest
+operates.
+

+

+The /+ modifier requests that as well as outputting the substring that
+matched the entire pattern, pcretest should in addition output the remainder of
+the subject string. This is useful for tests where the subject contains
+multiple copies of the same substring.
+

+

+The /B modifier is a debugging feature. It requests that pcretest
+output a representation of the compiled byte code after compilation. Normally
+this information contains length and offset values; however, if /Z is
+also present, this data is replaced by spaces. This is a special feature for
+use in the automatic test scripts; it ensures that the same output is generated
+for different internal link sizes.
+

+

+The /L modifier must be followed directly by the name of a locale, for
+example,
+
+  /pattern/Lfr_FR
+

+For this reason, it must be the last modifier. The given locale is set,
+pcre_maketables() is called to build a set of character tables for the
+locale, and this is then passed to pcre_compile() when compiling the
+regular expression. Without an /L modifier, NULL is passed as the tables
+pointer; that is, /L applies only to the expression on which it appears.
+

+

+The /I modifier requests that pcretest output information about the
+compiled pattern (whether it is anchored, has a fixed first character, and
+so on). It does this by calling pcre_fullinfo() after compiling a
+pattern. If the pattern is studied, the results of that are also output.
+

+

+The /D modifier is a PCRE debugging feature, and is equivalent to
+/BI, that is, both the /B and the /I modifiers.
+

+

+The /F modifier causes pcretest to flip the byte order of the
+fields in the compiled pattern that contain 2-byte and 4-byte numbers. This
+facility is for testing the feature in PCRE that allows it to execute patterns
+that were compiled on a host with a different endianness. This feature is not
+available when the POSIX interface to PCRE is being used, that is, when the
+/P pattern modifier is specified. See also the section about saving and
+reloading compiled patterns below.
+

+

+The /S modifier causes pcre_study() to be called after the
+expression has been compiled, and the results used when the expression is
+matched.
+

+

+The /M modifier causes the size of memory block used to hold the compiled
+pattern to be output.
+

+

+The /P modifier causes pcretest to call PCRE via the POSIX wrapper
+API rather than its native API. When this is done, all other modifiers except
+/i, /m, and /+ are ignored. REG_ICASE is set if /i is
+present, and REG_NEWLINE is set if /m is present. The wrapper functions
+force PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set.
+

+

+The /8 modifier causes pcretest to call PCRE with the PCRE_UTF8
+option set. This turns on support for UTF-8 character handling in PCRE,
+provided that it was compiled with this support enabled. This modifier also
+causes any non-printing characters in output strings to be printed using the
+\x{hh...} notation if they are valid UTF-8 sequences.
+

+

+If the /? modifier is used with /8, it causes pcretest to
+call pcre_compile() with the PCRE_NO_UTF8_CHECK option, to suppress the
+checking of the string for UTF-8 validity.
+

+
DATA LINES

+

+Before each data line is passed to pcre_exec(), leading and trailing
+whitespace is removed, and it is then scanned for \ escapes. Some of these are
+pretty esoteric features, intended for checking out some of the more
+complicated features of PCRE. If you are just testing "ordinary" regular
+expressions, you probably don't need any of these. The following escapes are
+recognized:
+
+  \a         alarm (BEL, \x07)
+  \b         backspace (\x08)
+  \e         escape (\x27)
+  \f         formfeed (\x0c)
+  \n         newline (\x0a)
+  \qdd       set the PCRE_MATCH_LIMIT limit to dd (any number of digits)
+  \r         carriage return (\x0d)
+  \t         tab (\x09)
+  \v         vertical tab (\x0b)
+  \nnn       octal character (up to 3 octal digits)
+  \xhh       hexadecimal character (up to 2 hex digits)
+  \x{hh...}  hexadecimal character, any number of digits in UTF-8 mode
+  \A         pass the PCRE_ANCHORED option to pcre_exec() or pcre_dfa_exec()
+  \B         pass the PCRE_NOTBOL option to pcre_exec() or pcre_dfa_exec()
+  \Cdd       call pcre_copy_substring() for substring dd after a successful match (number less than 32)
+  \Cname     call pcre_copy_named_substring() for substring "name" after a successful match (name termin-
+               ated by next non alphanumeric character)
+  \C+        show the current captured substrings at callout time
+  \C-        do not supply a callout function
+  \C!n       return 1 instead of 0 when callout number n is reached
+  \C!n!m     return 1 instead of 0 when callout number n is reached for the nth time
+  \C*n       pass the number n (may be negative) as callout data; this is used as the callout return value
+  \D         use the pcre_dfa_exec() match function
+  \F         only shortest match for pcre_dfa_exec()
+  \Gdd       call pcre_get_substring() for substring dd after a successful match (number less than 32)
+  \Gname     call pcre_get_named_substring() for substring "name" after a successful match (name termin-
+               ated by next non-alphanumeric character)
+  \L         call pcre_get_substringlist() after a successful match
+  \M         discover the minimum MATCH_LIMIT and MATCH_LIMIT_RECURSION settings
+  \N         pass the PCRE_NOTEMPTY option to pcre_exec() or pcre_dfa_exec(); if used twice, pass the
+               PCRE_NOTEMPTY_ATSTART option
+  \Odd       set the size of the output vector passed to pcre_exec() to dd (any number of digits)
+  \P         pass the PCRE_PARTIAL_SOFT option to pcre_exec() or pcre_dfa_exec(); if used twice, pass the
+               PCRE_PARTIAL_HARD option
+  \Qdd       set the PCRE_MATCH_LIMIT_RECURSION limit to dd (any number of digits)
+  \R         pass the PCRE_DFA_RESTART option to pcre_dfa_exec()
+  \S         output details of memory get/free calls during matching
+  \Y         pass the PCRE_NO_START_OPTIMIZE option to pcre_exec() or pcre_dfa_exec()
+  \Z         pass the PCRE_NOTEOL option to pcre_exec() or pcre_dfa_exec()
+  \?         pass the PCRE_NO_UTF8_CHECK option to pcre_exec() or pcre_dfa_exec()
+  \>dd       start the match at offset dd (any number of digits);
+               this sets the startoffset argument for pcre_exec() or pcre_dfa_exec()
+  \<cr>      pass the PCRE_NEWLINE_CR option to pcre_exec() or pcre_dfa_exec()
+  \<lf>      pass the PCRE_NEWLINE_LF option to pcre_exec() or pcre_dfa_exec()
+  \<crlf>    pass the PCRE_NEWLINE_CRLF option to pcre_exec() or pcre_dfa_exec()
+  \<anycrlf> pass the PCRE_NEWLINE_ANYCRLF option to pcre_exec() or pcre_dfa_exec()
+  \<any>     pass the PCRE_NEWLINE_ANY option to pcre_exec() or pcre_dfa_exec()
+

+The escapes that specify line ending sequences are literal strings, exactly as
+shown. No more than one newline setting should be present in any data line.
+

+

+A backslash followed by anything else just escapes the anything else. If
+the very last character is a backslash, it is ignored. This gives a way of
+passing an empty line as data, since a real empty line terminates the data
+input.
+

+

+If \M is present, pcretest calls pcre_exec() several times, with
+different values in the match_limit and match_limit_recursion
+fields of the pcre_extra data structure, until it finds the minimum
+numbers for each parameter that allow pcre_exec() to complete. The
+match_limit number is a measure of the amount of backtracking that takes
+place, and checking it out can be instructive. For most simple matches, the
+number is quite small, but for patterns with very large numbers of matching
+possibilities, it can become large very quickly with increasing length of
+subject string. The match_limit_recursion number is a measure of how much
+stack (or, if PCRE is compiled with NO_RECURSE, how much heap) memory is needed
+to complete the match attempt.
+

+

+When \O is used, the value specified may be higher or lower than the size set
+by the -O command line option (or defaulted to 45); \O applies only to
+the call of pcre_exec() for the line in which it appears.
+

+

+If the /P modifier was present on the pattern, causing the POSIX wrapper
+API to be used, the only option-setting sequences that have any effect are \B
+and \Z, causing REG_NOTBOL and REG_NOTEOL, respectively, to be passed to
+regexec().
+

+

+The use of \x{hh...} to represent UTF-8 characters is not dependent on the use
+of the /8 modifier on the pattern. It is recognized always. There may be
+any number of hexadecimal digits inside the braces. The result is from one to
+six bytes, encoded according to the original UTF-8 rules of RFC 2279. This
+allows for values in the range 0 to 0x7FFFFFFF. Note that not all of those are
+valid Unicode code points, or indeed valid UTF-8 characters according to the
+later rules in RFC 3629.
+

+
THE ALTERNATIVE MATCHING FUNCTION

+

+By default, pcretest uses the standard PCRE matching function,
+pcre_exec() to match each data line. From release 6.0, PCRE supports an
+alternative matching function, pcre_dfa_test(), which operates in a
+different way, and has some restrictions. The differences between the two
+functions are described in the
+pcrematching
+documentation.
+

+

+If a data line contains the \D escape sequence, or if the command line
+contains the -dfa option, the alternative matching function is called.
+This function finds all possible matches at a given point. If, however, the \F
+escape sequence is present in the data line, it stops after the first match is
+found. This is always the shortest possible match.
+

+
DEFAULT OUTPUT FROM PCRETEST

+

+This section describes the output when the normal matching function,
+pcre_exec(), is being used.
+

+

+When a match succeeds, pcretest outputs the list of captured substrings that
+pcre_exec() returns, starting with number 0 for the string that matched
+the whole pattern. Otherwise, it outputs "No match" when the return is
+PCRE_ERROR_NOMATCH, and "Partial match:" followed by the partially matching
+substring when pcre_exec() returns PCRE_ERROR_PARTIAL. For any other
+returns, it outputs the PCRE negative error number. Here is an example of an
+interactive pcretest run.
+
+  $ pcretest
+  PCRE version 7.0 30-Nov-2006
+
+    re> /^abc(\d+)/
+  data> abc123
+   0: abc123
+   1: 123
+  data> xyz
+  No match
+

+Note that unset capturing substrings that are not followed by one that is set
+are not returned by pcre_exec(), and are not shown by pcretest. In
+the following example, there are two capturing substrings, but when the first
+data line is matched, the second, unset substring is not shown. An "internal"
+unset substring is shown as "<unset>", as for the second data line.
+
+    re> /(a)|(b)/
+  data> a
+   0: a
+   1: a
+  data> b
+   0: b
+   1: <unset>
+   2: b
+

+If the strings contain any non-printing characters, they are output as \0x
+escapes, or as \x{...} escapes if the /8 modifier was present on the
+pattern. See below for the definition of non-printing characters. If the
+pattern has the /+ modifier, the output for substring 0 is followed by
+the the rest of the subject string, identified by "0+" like this:
+
+    re> /cat/+
+  data> cataract
+   0: cat
+   0+ aract
+

+If the pattern has the /g or /G modifier, the results of successive
+matching attempts are output in sequence, like this:
+
+    re> /\Bi(\w\w)/g
+  data> Mississippi
+   0: iss
+   1: ss
+   0: iss
+   1: ss
+   0: ipp
+   1: pp
+

+"No match" is output only if the first match attempt fails.
+

+

+If any of the sequences \C, \G, or \L are present in a
+data line that is successfully matched, the substrings extracted by the
+convenience functions are output with C, G, or L after the string number
+instead of a colon. This is in addition to the normal full list. The string
+length (that is, the return from the extraction function) is given in
+parentheses after each string for \C and \G.
+

+

+Note that whereas patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), data lines may not. However newlines can be
+included in data by means of the \n escape (or \r, \r\n, etc., depending on
+the newline sequence setting).
+

+
OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION

+

+When the alternative matching function, pcre_dfa_exec(), is used (by
+means of the \D escape sequence or the -dfa command line option), the
+output consists of a list of all the matches that start at the first point in
+the subject where there is at least one match. For example:
+
+    re> /(tang|tangerine|tan)/
+  data> yellow tangerine\D
+   0: tangerine
+   1: tang
+   2: tan
+

+(Using the normal matching function on this data finds only "tang".) The
+longest matching string is always given first (and numbered zero). After a
+PCRE_ERROR_PARTIAL return, the output is "Partial match:", followed by the
+partially matching substring.
+

+

+If /g is present on the pattern, the search for further matches resumes
+at the end of the longest match. For example:
+
+    re> /(tang|tangerine|tan)/g
+  data> yellow tangerine and tangy sultana\D
+   0: tangerine
+   1: tang
+   2: tan
+   0: tang
+   1: tan
+   0: tan
+

+Since the matching function does not support substring capture, the escape
+sequences that are concerned with captured substrings are not relevant.
+

+
RESTARTING AFTER A PARTIAL MATCH

+

+When the alternative matching function has given the PCRE_ERROR_PARTIAL return,
+indicating that the subject partially matched the pattern, you can restart the
+match with additional subject data by means of the \R escape sequence. For
+example:
+
+    re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+  data> 23ja\P\D
+  Partial match: 23ja
+  data> n05\R\D
+   0: n05
+

+For further information about partial matching, see the
+pcrepartial
+documentation.
+

+
CALLOUTS

+

+If the pattern contains any callout requests, pcretest's callout function
+is called during matching. This works with both matching functions. By default,
+the called function displays the callout number, the start and current
+positions in the text at the callout time, and the next pattern item to be
+tested. For example, the output
+
+  --->pqrabcdef
+    0    ^  ^     \d
+

+indicates that callout number 0 occurred for a match attempt starting at the
+fourth character of the subject string, when the pointer was at the seventh
+character of the data, and when the next pattern item was \d. Just one
+circumflex is output if the start and current positions are the same.
+

+

+Callouts numbered 255 are assumed to be automatic callouts, inserted as a
+result of the /C pattern modifier. In this case, instead of showing the
+callout number, the offset in the pattern, preceded by a plus, is output. For
+example:
+
+    re> /\d?[A-E]\*/C
+  data> E*
+  --->E*
+   +0 ^      \d?
+   +3 ^      [A-E]
+   +8 ^^     \*
+  +10 ^ ^
+   0: E*
+

+The callout function in pcretest returns zero (carry on matching) by
+default, but you can use a \C item in a data line (as described above) to
+change this.
+

+

+Inserting callouts can be helpful when using pcretest to check
+complicated regular expressions. For further information about callouts, see
+the
+pcrecallout
+documentation.
+

+
NON-PRINTING CHARACTERS

+

+When pcretest is outputting text in the compiled version of a pattern,
+bytes other than 32-126 are always treated as non-printing characters are are
+therefore shown as hex escapes.
+

+

+When pcretest is outputting text that is a matched part of a subject
+string, it behaves in the same way, unless a different locale has been set for
+the pattern (using the /L modifier). In this case, the isprint()
+function to distinguish printing and non-printing characters.
+

+
SAVING AND RELOADING COMPILED PATTERNS

+

+The facilities described in this section are not available when the POSIX
+inteface to PCRE is being used, that is, when the /P pattern modifier is
+specified.
+

+

+When the POSIX interface is not in use, you can cause pcretest to write a
+compiled pattern to a file, by following the modifiers with > and a file name.
+For example:
+
+  /pattern/im >/some/file
+

+See the
+pcreprecompile
+documentation for a discussion about saving and re-using compiled patterns.
+

+

+The data that is written is binary. The first eight bytes are the length of the
+compiled pattern data followed by the length of the optional study data, each
+written as four bytes in big-endian order (most significant byte first). If
+there is no study data (either the pattern was not studied, or studying did not
+return any data), the second length is zero. The lengths are followed by an
+exact copy of the compiled pattern. If there is additional study data, this
+follows immediately after the compiled pattern. After writing the file,
+pcretest expects to read a new pattern.
+

+

+A saved pattern can be reloaded into pcretest by specifing < and a file
+name instead of a pattern. The name of the file must not contain a < character,
+as otherwise pcretest will interpret the line as a pattern delimited by <
+characters.
+For example:
+
+   re> </some/file
+  Compiled regex loaded from /some/file
+  No study data
+

+When the pattern has been loaded, pcretest proceeds to read data lines in
+the usual way.
+

+

+You can copy a file written by pcretest to a different host and reload it
+there, even if the new host has opposite endianness to the one on which the
+pattern was compiled. For example, you can compile on an i86 machine and run on
+a SPARC machine.
+

+

+File names for saving and reloading can be absolute or relative, but note that
+the shell facility of expanding a file name that starts with a tilde (~) is not
+available.
+

+

+The ability to save and reload files in pcretest is intended for testing
+and experimentation. It is not intended for production use because only a
+single pattern can be written to a file. Furthermore, there is no facility for
+supplying custom character tables for use with a reloaded pattern. If the
+original pattern was compiled with custom tables, an attempt to match a subject
+string using a reloaded pattern is likely to cause pcretest to crash.
+Finally, if you attempt to load a file that is not in the correct format, the
+result is undefined.

+.TH PCRE 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH INTRODUCTION
+.rs
+.sp
+The PCRE library is a set of functions that implement regular expression
+pattern matching using the same syntax and semantics as Perl, with just a few
+differences. Some features that appeared in Python and PCRE before they
+appeared in Perl are also available using the Python syntax, there is some
+support for one or two .NET and Oniguruma syntax items, and there is an option
+for requesting some minor changes that give better JavaScript compatibility.
+.P
+The current implementation of PCRE corresponds approximately with Perl 5.10,
+including support for UTF-8 encoded strings and Unicode general category
+properties. However, UTF-8 and Unicode support has to be explicitly enabled; it
+is not the default. The Unicode tables correspond to Unicode release 5.1.
+.P
+In addition to the Perl-compatible matching function, PCRE contains an
+alternative function that matches the same compiled patterns in a different
+way. In certain circumstances, the alternative function has some advantages.
+For a discussion of the two matching algorithms, see the
+.\" HREF
+\fBpcrematching\fP
+.\"
+page.
+.P
+PCRE is written in C and released as a C library. A number of people have
+written wrappers and interfaces of various kinds. In particular, Google Inc.
+have provided a comprehensive C++ wrapper. This is now included as part of the
+PCRE distribution. The
+.\" HREF
+\fBpcrecpp\fP
+.\"
+page has details of this interface. Other people's contributions can be found
+in the \fIContrib\fR directory at the primary FTP site, which is:
+.sp
+.\" HTML 
+.\" 
+ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre
+.P
+Details of exactly which Perl regular expression features are and are not
+supported by PCRE are given in separate documents. See the
+.\" HREF
+\fBpcrepattern\fR
+.\"
+and
+.\" HREF
+\fBpcrecompat\fR
+.\"
+pages. There is a syntax summary in the
+.\" HREF
+\fBpcresyntax\fR
+.\"
+page.
+.P
+Some features of PCRE can be included, excluded, or changed when the library is
+built. The
+.\" HREF
+\fBpcre_config()\fR
+.\"
+function makes it possible for a client to discover which features are
+available. The features themselves are described in the
+.\" HREF
+\fBpcrebuild\fP
+.\"
+page. Documentation about building PCRE for various operating systems can be
+found in the \fBREADME\fP and \fBNON-UNIX-USE\fP files in the source
+distribution.
+.P
+The library contains a number of undocumented internal functions and data
+tables that are used by more than one of the exported external functions, but
+which are not intended for use by external callers. Their names all begin with
+"_pcre_", which hopefully will not provoke any name clashes. In some
+environments, it is possible to control which external symbols are exported
+when a shared library is built, and in these cases the undocumented symbols are
+not exported.
+.
+.
+.SH "USER DOCUMENTATION"
+.rs
+.sp
+The user documentation for PCRE comprises a number of different sections. In
+the "man" format, each of these is a separate "man page". In the HTML format,
+each is a separate page, linked from the index page. In the plain text format,
+all the sections, except the \fBpcredemo\fP section, are concatenated, for ease
+of searching. The sections are as follows:
+.sp
+  pcre              this document
+  pcre-config       show PCRE installation configuration information
+  pcreapi           details of PCRE's native C API
+  pcrebuild         options for building PCRE
+  pcrecallout       details of the callout feature
+  pcrecompat        discussion of Perl compatibility

+  pcregrep          description of the \fBpcregrep\fP command
+  pcrematching      discussion of the two matching algorithms
+  pcrepartial       details of the partial matching facility

+  pcretest          description of the \fBpcretest\fP testing command
+.sp
+In addition, in the "man" and HTML formats, there is a short page for each
+C library function, listing its arguments and results.
+.
+.
+.SH LIMITATIONS
+.rs
+.sp
+There are some size limitations in PCRE but it is hoped that they will never in
+practice be relevant.
+.P
+The maximum length of a compiled pattern is 65539 (sic) bytes if PCRE is
+compiled with the default internal linkage size of 2. If you want to process
+regular expressions that are truly enormous, you can compile PCRE with an
+internal linkage size of 3 or 4 (see the \fBREADME\fP file in the source
+distribution and the
+.\" HREF
+\fBpcrebuild\fP
+.\"
+documentation for details). In these cases the limit is substantially larger.
+However, the speed of execution is slower.
+.P
+All values in repeating quantifiers must be less than 65536.
+.P
+There is no limit to the number of parenthesized subpatterns, but there can be
+no more than 65535 capturing subpatterns.
+.P
+The maximum length of name for a named subpattern is 32 characters, and the
+maximum number of named subpatterns is 10000.
+.P
+The maximum length of a subject string is the largest positive number that an
+integer variable can hold. However, when using the traditional matching
+function, PCRE uses recursion to handle subpatterns and indefinite repetition.
+This means that the available stack space may limit the size of a subject
+string that can be processed by certain patterns. For a discussion of stack
+issues, see the
+.\" HREF
+\fBpcrestack\fP
+.\"
+documentation.
+.
+.
+.\" HTML 
+.
+.SH "UTF-8 AND UNICODE PROPERTY SUPPORT"
+.rs
+.sp
+From release 3.3, PCRE has had some support for character strings encoded in
+the UTF-8 format. For release 4.0 this was greatly extended to cover most
+common requirements, and in release 5.0 additional support for Unicode general
+category properties was added.
+.P
+In order process UTF-8 strings, you must build PCRE to include UTF-8 support in
+the code, and, in addition, you must call
+.\" HREF
+\fBpcre_compile()\fP
+.\"
+with the PCRE_UTF8 option flag, or the pattern must start with the sequence
+(*UTF8). When either of these is the case, both the pattern and any subject
+strings that are matched against it are treated as UTF-8 strings instead of
+strings of 1-byte characters.
+.P
+If you compile PCRE with UTF-8 support, but do not use it at run time, the
+library will be a bit bigger, but the additional run time overhead is limited
+to testing the PCRE_UTF8 flag occasionally, so should not be very big.
+.P
+If PCRE is built with Unicode character property support (which implies UTF-8
+support), the escape sequences \ep{..}, \eP{..}, and \eX are supported.
+The available properties that can be tested are limited to the general
+category properties such as Lu for an upper case letter or Nd for a decimal
+number, the Unicode script names such as Arabic or Han, and the derived
+properties Any and L&. A full list is given in the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+documentation. Only the short names for properties are supported. For example,
+\ep{L} matches a letter. Its Perl synonym, \ep{Letter}, is not supported.
+Furthermore, in Perl, many properties may optionally be prefixed by "Is", for
+compatibility with Perl 5.6. PCRE does not support this.
+.
+.
+.\" HTML 
+.
+.SS "Validity of UTF-8 strings"
+.rs
+.sp
+When you set the PCRE_UTF8 flag, the strings passed as patterns and subjects
+are (by default) checked for validity on entry to the relevant functions. From
+release 7.3 of PCRE, the check is according the rules of RFC 3629, which are
+themselves derived from the Unicode specification. Earlier releases of PCRE
+followed the rules of RFC 2279, which allows the full range of 31-bit values (0
+to 0x7FFFFFFF). The current check allows only values in the range U+0 to
+U+10FFFF, excluding U+D800 to U+DFFF.
+.P
+The excluded code points are the "Low Surrogate Area" of Unicode, of which the
+Unicode Standard says this: "The Low Surrogate Area does not contain any
+character assignments, consequently no character code charts or namelists are
+provided for this area. Surrogates are reserved for use with UTF-16 and then
+must be used in pairs." The code points that are encoded by UTF-16 pairs are
+available as independent code points in the UTF-8 encoding. (In other words,
+the whole surrogate thing is a fudge for UTF-16 which unfortunately messes up
+UTF-8.)
+.P
+If an invalid UTF-8 string is passed to PCRE, an error return
+(PCRE_ERROR_BADUTF8) is given. In some situations, you may already know that
+your strings are valid, and therefore want to skip these checks in order to
+improve performance. If you set the PCRE_NO_UTF8_CHECK flag at compile time or
+at run time, PCRE assumes that the pattern or subject it is given
+(respectively) contains only valid UTF-8 codes. In this case, it does not
+diagnose an invalid UTF-8 string.
+.P
+If you pass an invalid UTF-8 string when PCRE_NO_UTF8_CHECK is set, what
+happens depends on why the string is invalid. If the string conforms to the
+"old" definition of UTF-8 (RFC 2279), it is processed as a string of characters
+in the range 0 to 0x7FFFFFFF. In other words, apart from the initial validity
+test, PCRE (when in UTF-8 mode) handles strings according to the more liberal
+rules of RFC 2279. However, if the string does not even conform to RFC 2279,
+the result is undefined. Your program may crash.
+.P
+If you want to process strings of values in the full range 0 to 0x7FFFFFFF,
+encoded in a UTF-8-like manner as per the old RFC, you can set
+PCRE_NO_UTF8_CHECK to bypass the more restrictive test. However, in this
+situation, you will have to apply your own validity check.
+.
+.SS "General comments about UTF-8 mode"
+.rs
+.sp
+1. An unbraced hexadecimal escape sequence (such as \exb3) matches a two-byte
+UTF-8 character if the value is greater than 127.
+.P
+2. Octal numbers up to \e777 are recognized, and match two-byte UTF-8
+characters for values greater than \e177.
+.P
+3. Repeat quantifiers apply to complete UTF-8 characters, not to individual
+bytes, for example: \ex{100}{3}.
+.P
+4. The dot metacharacter matches one UTF-8 character instead of a single byte.
+.P
+5. The escape sequence \eC can be used to match a single byte in UTF-8 mode,
+but its use can lead to some strange effects. This facility is not available in
+the alternative matching function, \fBpcre_dfa_exec()\fP.
+.P
+6. The character escapes \eb, \eB, \ed, \eD, \es, \eS, \ew, and \eW correctly
+test characters of any code value, but the characters that PCRE recognizes as
+digits, spaces, or word characters remain the same set as before, all with
+values less than 256. This remains true even when PCRE includes Unicode
+property support, because to do otherwise would slow down PCRE in many common
+cases. If you really want to test for a wider sense of, say, "digit", you
+must use Unicode property tests such as \ep{Nd}. Note that this also applies to
+\eb, because it is defined in terms of \ew and \eW.
+.P
+7. Similarly, characters that match the POSIX named character classes are all
+low-valued characters.
+.P
+8. However, the Perl 5.10 horizontal and vertical whitespace matching escapes
+(\eh, \eH, \ev, and \eV) do match all the appropriate Unicode characters.
+.P
+9. Case-insensitive matching applies only to characters whose values are less
+than 128, unless PCRE is built with Unicode property support. Even when Unicode
+property support is available, PCRE still uses its own character tables when
+checking the case of low-valued characters, so as not to degrade performance.
+The Unicode property information is used only for characters with higher
+values. Even when Unicode property support is available, PCRE supports
+case-insensitive matching only when there is a one-to-one mapping between a
+letter's cases. There are a small number of many-to-one mappings in Unicode;
+these are not supported by PCRE.

+
+       Details of exactly which Perl regular expression features are  and  are
+       not supported by PCRE are given in separate documents. See the pcrepat-
+       tern and pcrecompat pages. There is a syntax summary in the  pcresyntax
+       page.
+
+       Some  features  of  PCRE can be included, excluded, or changed when the

+
+       There are some size limitations in PCRE but it is hoped that they  will
+       never in practice be relevant.
+
+       The  maximum  length of a compiled pattern is 65539 (sic) bytes if PCRE
+       is compiled with the default internal linkage size of 2. If you want to
+       process  regular  expressions  that are truly enormous, you can compile
+       PCRE with an internal linkage size of 3 or 4 (see the  README  file  in
+       the  source  distribution and the pcrebuild documentation for details).
+       In these cases the limit is substantially larger.  However,  the  speed
+       of execution is slower.
+
+       All values in repeating quantifiers must be less than 65536.
+
+       There is no limit to the number of parenthesized subpatterns, but there
+       can be no more than 65535 capturing subpatterns.
+
+       The maximum length of name for a named subpattern is 32 characters, and
+       the maximum number of named subpatterns is 10000.
+
+       The  maximum  length of a subject string is the largest positive number
+       that an integer variable can hold. However, when using the  traditional
+       matching function, PCRE uses recursion to handle subpatterns and indef-
+       inite repetition.  This means that the available stack space may  limit
+       the size of a subject string that can be processed by certain patterns.
+       For a discussion of stack issues, see the pcrestack documentation.
+
+
+UTF-8 AND UNICODE PROPERTY SUPPORT
+
+       From release 3.3, PCRE has  had  some  support  for  character  strings
+       encoded  in the UTF-8 format. For release 4.0 this was greatly extended
+       to cover most common requirements, and in release 5.0  additional  sup-
+       port for Unicode general category properties was added.
+
+       In  order  process  UTF-8 strings, you must build PCRE to include UTF-8
+       support in the code, and, in addition,  you  must  call  pcre_compile()
+       with  the  PCRE_UTF8  option  flag,  or the pattern must start with the
+       sequence (*UTF8). When either of these is the case,  both  the  pattern
+       and  any  subject  strings  that  are matched against it are treated as
+       UTF-8 strings instead of strings of 1-byte characters.
+
+       If you compile PCRE with UTF-8 support, but do not use it at run  time,
+       the  library will be a bit bigger, but the additional run time overhead
+       is limited to testing the PCRE_UTF8 flag occasionally, so should not be
+       very big.
+
+       If PCRE is built with Unicode character property support (which implies
+       UTF-8 support), the escape sequences \p{..}, \P{..}, and  \X  are  sup-
+       ported.  The available properties that can be tested are limited to the
+       general category properties such as Lu for an upper case letter  or  Nd
+       for  a  decimal number, the Unicode script names such as Arabic or Han,
+       and the derived properties Any and L&. A full  list  is  given  in  the
+       pcrepattern documentation. Only the short names for properties are sup-
+       ported. For example, \p{L} matches a letter. Its Perl synonym,  \p{Let-
+       ter},  is  not  supported.   Furthermore,  in Perl, many properties may
+       optionally be prefixed by "Is", for compatibility with Perl  5.6.  PCRE
+       does not support this.
+
+   Validity of UTF-8 strings
+
+       When  you  set  the  PCRE_UTF8 flag, the strings passed as patterns and
+       subjects are (by default) checked for validity on entry to the relevant
+       functions.  From  release 7.3 of PCRE, the check is according the rules
+       of RFC 3629, which are themselves derived from the  Unicode  specifica-
+       tion.  Earlier  releases  of PCRE followed the rules of RFC 2279, which
+       allows the full range of 31-bit values (0 to 0x7FFFFFFF).  The  current
+       check allows only values in the range U+0 to U+10FFFF, excluding U+D800
+       to U+DFFF.
+
+       The excluded code points are the "Low Surrogate Area"  of  Unicode,  of
+       which  the Unicode Standard says this: "The Low Surrogate Area does not
+       contain any  character  assignments,  consequently  no  character  code
+       charts or namelists are provided for this area. Surrogates are reserved
+       for use with UTF-16 and then must be used in pairs."  The  code  points
+       that  are  encoded  by  UTF-16  pairs are available as independent code
+       points in the UTF-8 encoding. (In  other  words,  the  whole  surrogate
+       thing is a fudge for UTF-16 which unfortunately messes up UTF-8.)
+
+       If  an  invalid  UTF-8  string  is  passed  to  PCRE,  an  error return
+       (PCRE_ERROR_BADUTF8) is given. In some situations, you may already know
+       that your strings are valid, and therefore want to skip these checks in
+       order to improve performance. If you set the PCRE_NO_UTF8_CHECK flag at
+       compile  time  or at run time, PCRE assumes that the pattern or subject
+       it is given (respectively) contains only valid  UTF-8  codes.  In  this
+       case, it does not diagnose an invalid UTF-8 string.
+
+       If  you  pass  an  invalid UTF-8 string when PCRE_NO_UTF8_CHECK is set,
+       what happens depends on why the string is invalid. If the  string  con-
+       forms to the "old" definition of UTF-8 (RFC 2279), it is processed as a
+       string of characters in the range 0  to  0x7FFFFFFF.  In  other  words,
+       apart from the initial validity test, PCRE (when in UTF-8 mode) handles
+       strings according to the more liberal rules of RFC  2279.  However,  if
+       the  string does not even conform to RFC 2279, the result is undefined.
+       Your program may crash.
+
+       If you want to process strings  of  values  in  the  full  range  0  to
+       0x7FFFFFFF,  encoded in a UTF-8-like manner as per the old RFC, you can
+       set PCRE_NO_UTF8_CHECK to bypass the more restrictive test. However, in
+       this situation, you will have to apply your own validity check.
+
+   General comments about UTF-8 mode
+
+       1.  An  unbraced  hexadecimal  escape sequence (such as \xb3) matches a
+       two-byte UTF-8 character if the value is greater than 127.
+
+       2. Octal numbers up to \777 are recognized, and  match  two-byte  UTF-8
+       characters for values greater than \177.
+
+       3.  Repeat quantifiers apply to complete UTF-8 characters, not to indi-
+       vidual bytes, for example: \x{100}{3}.
+
+       4. The dot metacharacter matches one UTF-8 character instead of a  sin-
+       gle byte.
+
+       5.  The  escape sequence \C can be used to match a single byte in UTF-8
+       mode, but its use can lead to some strange effects.  This  facility  is
+       not available in the alternative matching function, pcre_dfa_exec().
+
+       6.  The  character escapes \b, \B, \d, \D, \s, \S, \w, and \W correctly
+       test characters of any code value, but the characters that PCRE  recog-
+       nizes  as  digits,  spaces,  or  word characters remain the same set as
+       before, all with values less than 256. This remains true even when PCRE
+       includes  Unicode  property support, because to do otherwise would slow
+       down PCRE in many common cases. If you really want to test for a  wider
+       sense  of,  say,  "digit",  you must use Unicode property tests such as
+       \p{Nd}. Note that this also applies to \b, because  it  is  defined  in
+       terms of \w and \W.
+
+       7.  Similarly,  characters that match the POSIX named character classes
+       are all low-valued characters.
+
+       8. However, the Perl 5.10 horizontal and vertical  whitespace  matching
+       escapes (\h, \H, \v, and \V) do match all the appropriate Unicode char-
+       acters.
+
+       9. Case-insensitive matching applies only to  characters  whose  values
+       are  less than 128, unless PCRE is built with Unicode property support.
+       Even when Unicode property support is available, PCRE  still  uses  its
+       own  character  tables when checking the case of low-valued characters,
+       so as not to degrade performance.  The Unicode property information  is
+       used only for characters with higher values. Even when Unicode property
+       support is available, PCRE supports case-insensitive matching only when
+       there  is  a  one-to-one  mapping between a letter's cases. There are a
+       small number of many-to-one mappings in Unicode;  these  are  not  sup-
+       ported by PCRE.

+
+PCRE BUILD-TIME OPTIONS
+
+       This  document  describes  the  optional  features  of PCRE that can be
+       selected when the library is compiled. It assumes use of the  configure
+       script,  where the optional features are selected or deselected by pro-
+       viding options to configure before running the make  command.  However,
+       the  same  options  can be selected in both Unix-like and non-Unix-like
+       environments using the GUI facility of cmake-gui if you are using CMake
+       instead of configure to build PCRE.
+
+       There  is  a  lot more information about building PCRE in non-Unix-like
+       environments in the file called NON_UNIX_USE, which is part of the PCRE
+       distribution.  You  should consult this file as well as the README file
+       if you are building in a non-Unix-like environment.
+
+       The complete list of options for configure (which includes the standard
+       ones  such  as  the  selection  of  the  installation directory) can be
+       obtained by running
+
+         ./configure --help
+
+       The following sections include  descriptions  of  options  whose  names
+       begin with --enable or --disable. These settings specify changes to the
+       defaults for the configure command. Because of the way  that  configure
+       works,  --enable  and --disable always come in pairs, so the complemen-
+       tary option always exists as well, but as it specifies the default,  it
+       is not described.
+
+
+C++ SUPPORT
+
+       By default, the configure script will search for a C++ compiler and C++
+       header files. If it finds them, it automatically builds the C++ wrapper
+       library for PCRE. You can disable this by adding
+
+         --disable-cpp
+
+       to the configure command.
+
+
+UTF-8 SUPPORT
+
+       To build PCRE with support for UTF-8 Unicode character strings, add
+
+         --enable-utf8
+
+       to  the  configure  command.  Of  itself, this does not make PCRE treat
+       strings as UTF-8. As well as compiling PCRE with this option, you  also
+       have  have to set the PCRE_UTF8 option when you call the pcre_compile()
+       or pcre_compile2() functions.
+
+       If you set --enable-utf8 when compiling in an EBCDIC environment,  PCRE
+       expects its input to be either ASCII or UTF-8 (depending on the runtime
+       option). It is not possible to support both EBCDIC and UTF-8  codes  in
+       the  same  version  of  the  library.  Consequently,  --enable-utf8 and
+       --enable-ebcdic are mutually exclusive.
+
+
+UNICODE CHARACTER PROPERTY SUPPORT
+
+       UTF-8 support allows PCRE to process character values greater than  255
+       in  the  strings that it handles. On its own, however, it does not pro-
+       vide any facilities for accessing the properties of such characters. If
+       you  want  to  be able to use the pattern escapes \P, \p, and \X, which
+       refer to Unicode character properties, you must add
+
+         --enable-unicode-properties
+
+       to the configure command. This implies UTF-8 support, even if you  have
+       not explicitly requested it.
+
+       Including  Unicode  property  support  adds around 30K of tables to the
+       PCRE library. Only the general category properties such as  Lu  and  Nd
+       are supported. Details are given in the pcrepattern documentation.
+
+
+CODE VALUE OF NEWLINE
+
+       By  default,  PCRE interprets the linefeed (LF) character as indicating
+       the end of a line. This is the normal newline  character  on  Unix-like
+       systems.  You  can compile PCRE to use carriage return (CR) instead, by
+       adding
+
+         --enable-newline-is-cr
+
+       to the  configure  command.  There  is  also  a  --enable-newline-is-lf
+       option, which explicitly specifies linefeed as the newline character.
+
+       Alternatively, you can specify that line endings are to be indicated by
+       the two character sequence CRLF. If you want this, add
+
+         --enable-newline-is-crlf
+
+       to the configure command. There is a fourth option, specified by
+
+         --enable-newline-is-anycrlf
+
+       which causes PCRE to recognize any of the three sequences  CR,  LF,  or
+       CRLF as indicating a line ending. Finally, a fifth option, specified by
+
+         --enable-newline-is-any
+
+       causes PCRE to recognize any Unicode newline sequence.
+
+       Whatever  line  ending convention is selected when PCRE is built can be
+       overridden when the library functions are called. At build time  it  is
+       conventional to use the standard for your operating system.
+
+
+WHAT \R MATCHES
+
+       By  default,  the  sequence \R in a pattern matches any Unicode newline
+       sequence, whatever has been selected as the line  ending  sequence.  If
+       you specify
+
+         --enable-bsr-anycrlf
+
+       the  default  is changed so that \R matches only CR, LF, or CRLF. What-
+       ever is selected when PCRE is built can be overridden when the  library
+       functions are called.
+
+
+BUILDING SHARED AND STATIC LIBRARIES
+
+       The  PCRE building process uses libtool to build both shared and static
+       Unix libraries by default. You can suppress one of these by adding  one
+       of
+
+         --disable-shared
+         --disable-static
+
+       to the configure command, as required.
+
+
+POSIX MALLOC USAGE
+
+       When PCRE is called through the POSIX interface (see the pcreposix doc-
+       umentation), additional working storage is  required  for  holding  the
+       pointers  to capturing substrings, because PCRE requires three integers
+       per substring, whereas the POSIX interface provides only  two.  If  the
+       number of expected substrings is small, the wrapper function uses space
+       on the stack, because this is faster than using malloc() for each call.
+       The default threshold above which the stack is no longer used is 10; it
+       can be changed by adding a setting such as
+
+         --with-posix-malloc-threshold=20
+
+       to the configure command.
+
+
+HANDLING VERY LARGE PATTERNS
+
+       Within a compiled pattern, offset values are used  to  point  from  one
+       part  to another (for example, from an opening parenthesis to an alter-
+       nation metacharacter). By default, two-byte values are used  for  these
+       offsets,  leading  to  a  maximum size for a compiled pattern of around
+       64K. This is sufficient to handle all but the most  gigantic  patterns.
+       Nevertheless,  some  people do want to process truyl enormous patterns,
+       so it is possible to compile PCRE to use three-byte or  four-byte  off-
+       sets by adding a setting such as
+
+         --with-link-size=3
+
+       to  the  configure  command.  The value given must be 2, 3, or 4. Using
+       longer offsets slows down the operation of PCRE because it has to  load
+       additional bytes when handling them.
+
+
+AVOIDING EXCESSIVE STACK USAGE
+
+       When matching with the pcre_exec() function, PCRE implements backtrack-
+       ing by making recursive calls to an internal function  called  match().
+       In  environments  where  the size of the stack is limited, this can se-
+       verely limit PCRE's operation. (The Unix environment does  not  usually
+       suffer from this problem, but it may sometimes be necessary to increase
+       the maximum stack size.  There is a discussion in the  pcrestack  docu-
+       mentation.)  An alternative approach to recursion that uses memory from
+       the heap to remember data, instead of using recursive  function  calls,
+       has  been  implemented to work round the problem of limited stack size.
+       If you want to build a version of PCRE that works this way, add
+
+         --disable-stack-for-recursion
+
+       to the configure command. With this configuration, PCRE  will  use  the
+       pcre_stack_malloc  and pcre_stack_free variables to call memory manage-
+       ment functions. By default these point to malloc() and free(), but  you
+       can replace the pointers so that your own functions are used instead.
+
+       Separate  functions  are  provided  rather  than  using pcre_malloc and
+       pcre_free because the  usage  is  very  predictable:  the  block  sizes
+       requested  are  always  the  same,  and  the blocks are always freed in
+       reverse order. A calling program might be able to  implement  optimized
+       functions  that  perform  better  than  malloc()  and free(). PCRE runs
+       noticeably more slowly when built in this way. This option affects only
+       the pcre_exec() function; it is not relevant for pcre_dfa_exec().
+
+
+LIMITING PCRE RESOURCE USAGE
+
+       Internally,  PCRE has a function called match(), which it calls repeat-
+       edly  (sometimes  recursively)  when  matching  a  pattern   with   the
+       pcre_exec()  function.  By controlling the maximum number of times this
+       function may be called during a single matching operation, a limit  can
+       be  placed  on  the resources used by a single call to pcre_exec(). The
+       limit can be changed at run time, as described in the pcreapi  documen-
+       tation.  The default is 10 million, but this can be changed by adding a
+       setting such as
+
+         --with-match-limit=500000
+
+       to  the  configure  command.  This  setting  has  no  effect   on   the
+       pcre_dfa_exec() matching function.
+
+       In  some  environments  it is desirable to limit the depth of recursive
+       calls of match() more strictly than the total number of calls, in order
+       to  restrict  the maximum amount of stack (or heap, if --disable-stack-
+       for-recursion is specified) that is used. A second limit controls this;
+       it  defaults  to  the  value  that is set for --with-match-limit, which
+       imposes no additional constraints. However, you can set a  lower  limit
+       by adding, for example,
+
+         --with-match-limit-recursion=10000
+
+       to  the  configure  command.  This  value can also be overridden at run
+       time.
+
+
+CREATING CHARACTER TABLES AT BUILD TIME
+
+       PCRE uses fixed tables for processing characters whose code values  are
+       less  than 256. By default, PCRE is built with a set of tables that are
+       distributed in the file pcre_chartables.c.dist. These  tables  are  for
+       ASCII codes only. If you add
+
+         --enable-rebuild-chartables
+
+       to  the  configure  command, the distributed tables are no longer used.
+       Instead, a program called dftables is compiled and  run.  This  outputs
+       the source for new set of tables, created in the default locale of your
+       C runtime system. (This method of replacing the tables does not work if
+       you  are cross compiling, because dftables is run on the local host. If
+       you need to create alternative tables when cross  compiling,  you  will
+       have to do so "by hand".)
+
+
+USING EBCDIC CODE
+
+       PCRE  assumes  by  default that it will run in an environment where the
+       character code is ASCII (or Unicode, which is  a  superset  of  ASCII).
+       This  is  the  case for most computer operating systems. PCRE can, how-
+       ever, be compiled to run in an EBCDIC environment by adding
+
+         --enable-ebcdic
+
+       to the configure command. This setting implies --enable-rebuild-charta-
+       bles.  You  should  only  use  it if you know that you are in an EBCDIC
+       environment (for example,  an  IBM  mainframe  operating  system).  The
+       --enable-ebcdic option is incompatible with --enable-utf8.
+
+
+PCREGREP OPTIONS FOR COMPRESSED FILE SUPPORT
+
+       By default, pcregrep reads all files as plain text. You can build it so
+       that it recognizes files whose names end in .gz or .bz2, and reads them
+       with libz or libbz2, respectively, by adding one or both of
+
+         --enable-pcregrep-libz
+         --enable-pcregrep-libbz2
+
+       to the configure command. These options naturally require that the rel-
+       evant libraries are installed on your system. Configuration  will  fail
+       if they are not.
+
+
+PCRETEST OPTION FOR LIBREADLINE SUPPORT
+
+       If you add
+
+         --enable-pcretest-libreadline
+
+       to  the  configure  command,  pcretest  is  linked with the libreadline
+       library, and when its input is from a terminal, it reads it  using  the
+       readline() function. This provides line-editing and history facilities.
+       Note that libreadline is GPL-licensed, so if you distribute a binary of
+       pcretest linked in this way, there may be licensing issues.
+
+       Setting  this  option  causes  the -lreadline option to be added to the
+       pcretest build. In many operating environments with  a  sytem-installed
+       libreadline this is sufficient. However, in some environments (e.g.  if
+       an unmodified distribution version of readline is in use),  some  extra
+       configuration  may  be necessary. The INSTALL file for libreadline says
+       this:
+
+         "Readline uses the termcap functions, but does not link with the
+         termcap or curses library itself, allowing applications which link
+         with readline the to choose an appropriate library."
+
+       If your environment has not been set up so that an appropriate  library
+       is automatically included, you may need to add something like
+
+         LIBS="-ncurses"
+
+       immediately before the configure command.

+PCRE MATCHING ALGORITHMS
+
+       This document describes the two different algorithms that are available
+       in PCRE for matching a compiled regular expression against a given sub-
+       ject  string.  The  "standard"  algorithm  is  the  one provided by the
+       pcre_exec() function.  This works in the same was  as  Perl's  matching
+       function, and provides a Perl-compatible matching operation.
+
+       An  alternative  algorithm is provided by the pcre_dfa_exec() function;
+       this operates in a different way, and is not  Perl-compatible.  It  has
+       advantages  and disadvantages compared with the standard algorithm, and
+       these are described below.
+
+       When there is only one possible way in which a given subject string can
+       match  a pattern, the two algorithms give the same answer. A difference
+       arises, however, when there are multiple possibilities. For example, if
+       the pattern
+
+         ^<.*>
+
+       is matched against the string
+
+           
+
+       there are three possible answers. The standard algorithm finds only one
+       of them, whereas the alternative algorithm finds all three.
+
+
+REGULAR EXPRESSIONS AS TREES
+
+       The set of strings that are matched by a regular expression can be rep-
+       resented  as  a  tree structure. An unlimited repetition in the pattern
+       makes the tree of infinite size, but it is still a tree.  Matching  the
+       pattern  to a given subject string (from a given starting point) can be
+       thought of as a search of the tree.  There are two  ways  to  search  a
+       tree:  depth-first  and  breadth-first, and these correspond to the two
+       matching algorithms provided by PCRE.
+
+
+THE STANDARD MATCHING ALGORITHM
+
+       In the terminology of Jeffrey Friedl's book "Mastering Regular  Expres-
+       sions",  the  standard  algorithm  is an "NFA algorithm". It conducts a
+       depth-first search of the pattern tree. That is, it  proceeds  along  a
+       single path through the tree, checking that the subject matches what is
+       required. When there is a mismatch, the algorithm  tries  any  alterna-
+       tives  at  the  current point, and if they all fail, it backs up to the
+       previous branch point in the  tree,  and  tries  the  next  alternative
+       branch  at  that  level.  This often involves backing up (moving to the
+       left) in the subject string as well.  The  order  in  which  repetition
+       branches  are  tried  is controlled by the greedy or ungreedy nature of
+       the quantifier.
+
+       If a leaf node is reached, a matching string has  been  found,  and  at
+       that  point the algorithm stops. Thus, if there is more than one possi-
+       ble match, this algorithm returns the first one that it finds.  Whether
+       this  is the shortest, the longest, or some intermediate length depends
+       on the way the greedy and ungreedy repetition quantifiers are specified
+       in the pattern.
+
+       Because  it  ends  up  with a single path through the tree, it is rela-
+       tively straightforward for this algorithm to keep  track  of  the  sub-
+       strings  that  are  matched  by portions of the pattern in parentheses.
+       This provides support for capturing parentheses and back references.
+
+
+THE ALTERNATIVE MATCHING ALGORITHM
+
+       This algorithm conducts a breadth-first search of  the  tree.  Starting
+       from  the  first  matching  point  in the subject, it scans the subject
+       string from left to right, once, character by character, and as it does
+       this,  it remembers all the paths through the tree that represent valid
+       matches. In Friedl's terminology, this is a kind  of  "DFA  algorithm",
+       though  it is not implemented as a traditional finite state machine (it
+       keeps multiple states active simultaneously).
+
+       Although the general principle of this matching algorithm  is  that  it
+       scans  the subject string only once, without backtracking, there is one
+       exception: when a lookaround assertion is encountered,  the  characters
+       following  or  preceding  the  current  point  have to be independently
+       inspected.
+
+       The scan continues until either the end of the subject is  reached,  or
+       there  are  no more unterminated paths. At this point, terminated paths
+       represent the different matching possibilities (if there are none,  the
+       match  has  failed).   Thus,  if there is more than one possible match,
+       this algorithm finds all of them, and in particular, it finds the long-
+       est.  There  is  an  option to stop the algorithm after the first match
+       (which is necessarily the shortest) is found.
+
+       Note that all the matches that are found start at the same point in the
+       subject. If the pattern
+
+         cat(er(pillar)?)
+
+       is  matched  against the string "the caterpillar catchment", the result
+       will be the three strings "cat", "cater", and "caterpillar" that  start
+       at the fourth character of the subject. The algorithm does not automat-
+       ically move on to find matches that start at later positions.
+
+       There are a number of features of PCRE regular expressions that are not
+       supported by the alternative matching algorithm. They are as follows:
+
+       1.  Because  the  algorithm  finds  all possible matches, the greedy or
+       ungreedy nature of repetition quantifiers is not relevant.  Greedy  and
+       ungreedy quantifiers are treated in exactly the same way. However, pos-
+       sessive quantifiers can make a difference when what follows could  also
+       match what is quantified, for example in a pattern like this:
+
+         ^a++\w!
+
+       This  pattern matches "aaab!" but not "aaa!", which would be matched by
+       a non-possessive quantifier. Similarly, if an atomic group is  present,
+       it  is matched as if it were a standalone pattern at the current point,
+       and the longest match is then "locked in" for the rest of  the  overall
+       pattern.
+
+       2. When dealing with multiple paths through the tree simultaneously, it
+       is not straightforward to keep track of  captured  substrings  for  the
+       different  matching  possibilities,  and  PCRE's implementation of this
+       algorithm does not attempt to do this. This means that no captured sub-
+       strings are available.
+
+       3.  Because no substrings are captured, back references within the pat-
+       tern are not supported, and cause errors if encountered.
+
+       4. For the same reason, conditional expressions that use  a  backrefer-
+       ence  as  the  condition or test for a specific group recursion are not
+       supported.
+
+       5. Because many paths through the tree may be  active,  the  \K  escape
+       sequence, which resets the start of the match when encountered (but may
+       be on some paths and not on others), is not  supported.  It  causes  an
+       error if encountered.
+
+       6.  Callouts  are  supported, but the value of the capture_top field is
+       always 1, and the value of the capture_last field is always -1.
+
+       7. The \C escape sequence, which (in the standard algorithm) matches  a
+       single  byte, even in UTF-8 mode, is not supported because the alterna-
+       tive algorithm moves through the subject  string  one  character  at  a
+       time, for all active paths through the tree.
+
+       8.  Except for (*FAIL), the backtracking control verbs such as (*PRUNE)
+       are not supported. (*FAIL) is supported, and  behaves  like  a  failing
+       negative assertion.
+
+
+ADVANTAGES OF THE ALTERNATIVE ALGORITHM
+
+       Using  the alternative matching algorithm provides the following advan-
+       tages:
+
+       1. All possible matches (at a single point in the subject) are automat-
+       ically  found,  and  in particular, the longest match is found. To find
+       more than one match using the standard algorithm, you have to do kludgy
+       things with callouts.
+
+       2.  Because  the  alternative  algorithm  scans the subject string just
+       once, and never needs to backtrack, it is possible to  pass  very  long
+       subject  strings  to  the matching function in several pieces, checking
+       for partial matching each time.  The  pcrepartial  documentation  gives
+       details of partial matching.
+
+
+DISADVANTAGES OF THE ALTERNATIVE ALGORITHM
+
+       The alternative algorithm suffers from a number of disadvantages:
+
+       1.  It  is  substantially  slower  than the standard algorithm. This is
+       partly because it has to search for all possible matches, but  is  also
+       because it is less susceptible to optimization.
+
+       2. Capturing parentheses and back references are not supported.
+
+       3. Although atomic groups are supported, their use does not provide the
+       performance advantage that it does for the standard algorithm.

+
+PCRE API OVERVIEW
+
+       PCRE has its own native API, which is described in this document. There
+       are also some wrapper functions that correspond to  the  POSIX  regular
+       expression  API.  These  are  described in the pcreposix documentation.
+       Both of these APIs define a set of C function calls. A C++  wrapper  is
+       distributed with PCRE. It is documented in the pcrecpp page.
+
+       The  native  API  C  function prototypes are defined in the header file
+       pcre.h, and on Unix systems the library itself is called  libpcre.   It
+       can normally be accessed by adding -lpcre to the command for linking an
+       application  that  uses  PCRE.  The  header  file  defines  the  macros
+       PCRE_MAJOR  and  PCRE_MINOR to contain the major and minor release num-
+       bers for the library.  Applications can use these  to  include  support
+       for different releases of PCRE.
+
+       The   functions   pcre_compile(),  pcre_compile2(),  pcre_study(),  and
+       pcre_exec() are used for compiling and matching regular expressions  in
+       a  Perl-compatible  manner. A sample program that demonstrates the sim-
+       plest way of using them is provided in the file  called  pcredemo.c  in
+       the PCRE source distribution. A listing of this program is given in the
+       pcredemo documentation, and the pcresample documentation describes  how
+       to compile and run it.
+
+       A second matching function, pcre_dfa_exec(), which is not Perl-compati-
+       ble, is also provided. This uses a different algorithm for  the  match-
+       ing.  The  alternative algorithm finds all possible matches (at a given
+       point in the subject), and scans the subject just  once  (unless  there
+       are  lookbehind  assertions).  However,  this algorithm does not return
+       captured substrings. A description of the two matching  algorithms  and
+       their  advantages  and disadvantages is given in the pcrematching docu-
+       mentation.
+
+       In addition to the main compiling and  matching  functions,  there  are
+       convenience functions for extracting captured substrings from a subject
+       string that is matched by pcre_exec(). They are:
+
+         pcre_copy_substring()
+         pcre_copy_named_substring()
+         pcre_get_substring()
+         pcre_get_named_substring()
+         pcre_get_substring_list()
+         pcre_get_stringnumber()
+         pcre_get_stringtable_entries()
+
+       pcre_free_substring() and pcre_free_substring_list() are also provided,
+       to free the memory used for extracted strings.
+
+       The  function  pcre_maketables()  is  used  to build a set of character
+       tables  in  the  current  locale   for   passing   to   pcre_compile(),
+       pcre_exec(),  or  pcre_dfa_exec(). This is an optional facility that is
+       provided for specialist use.  Most  commonly,  no  special  tables  are
+       passed,  in  which case internal tables that are generated when PCRE is
+       built are used.
+
+       The function pcre_fullinfo() is used to find out  information  about  a
+       compiled  pattern; pcre_info() is an obsolete version that returns only
+       some of the available information, but is retained for  backwards  com-
+       patibility.   The function pcre_version() returns a pointer to a string
+       containing the version of PCRE and its date of release.
+
+       The function pcre_refcount() maintains a  reference  count  in  a  data
+       block  containing  a compiled pattern. This is provided for the benefit
+       of object-oriented applications.
+
+       The global variables pcre_malloc and pcre_free  initially  contain  the
+       entry  points  of  the  standard malloc() and free() functions, respec-
+       tively. PCRE calls the memory management functions via these variables,
+       so  a  calling  program  can replace them if it wishes to intercept the
+       calls. This should be done before calling any PCRE functions.
+
+       The global variables pcre_stack_malloc  and  pcre_stack_free  are  also
+       indirections  to  memory  management functions. These special functions
+       are used only when PCRE is compiled to use  the  heap  for  remembering
+       data, instead of recursive function calls, when running the pcre_exec()
+       function. See the pcrebuild documentation for  details  of  how  to  do
+       this.  It  is  a non-standard way of building PCRE, for use in environ-
+       ments that have limited stacks. Because of the greater  use  of  memory
+       management,  it  runs  more  slowly. Separate functions are provided so
+       that special-purpose external code can be  used  for  this  case.  When
+       used,  these  functions  are always called in a stack-like manner (last
+       obtained, first freed), and always for memory blocks of the same  size.
+       There  is  a discussion about PCRE's stack usage in the pcrestack docu-
+       mentation.
+
+       The global variable pcre_callout initially contains NULL. It can be set
+       by  the  caller  to  a "callout" function, which PCRE will then call at
+       specified points during a matching operation. Details are given in  the
+       pcrecallout documentation.
+
+
+NEWLINES
+
+       PCRE  supports five different conventions for indicating line breaks in
+       strings: a single CR (carriage return) character, a  single  LF  (line-
+       feed) character, the two-character sequence CRLF, any of the three pre-
+       ceding, or any Unicode newline sequence. The Unicode newline  sequences
+       are  the  three just mentioned, plus the single characters VT (vertical
+       tab, U+000B), FF (formfeed, U+000C), NEL (next line, U+0085), LS  (line
+       separator, U+2028), and PS (paragraph separator, U+2029).
+
+       Each  of  the first three conventions is used by at least one operating
+       system as its standard newline sequence. When PCRE is built, a  default
+       can  be  specified.  The default default is LF, which is the Unix stan-
+       dard. When PCRE is run, the default can be overridden,  either  when  a
+       pattern is compiled, or when it is matched.
+
+       At compile time, the newline convention can be specified by the options
+       argument of pcre_compile(), or it can be specified by special  text  at
+       the start of the pattern itself; this overrides any other settings. See
+       the pcrepattern page for details of the special character sequences.
+
+       In the PCRE documentation the word "newline" is used to mean "the char-
+       acter  or pair of characters that indicate a line break". The choice of
+       newline convention affects the handling of  the  dot,  circumflex,  and
+       dollar metacharacters, the handling of #-comments in /x mode, and, when
+       CRLF is a recognized line ending sequence, the match position  advance-
+       ment for a non-anchored pattern. There is more detail about this in the
+       section on pcre_exec() options below.
+
+       The choice of newline convention does not affect the interpretation  of
+       the  \n  or  \r  escape  sequences, nor does it affect what \R matches,
+       which is controlled in a similar way, but by separate options.
+
+
+MULTITHREADING
+
+       The PCRE functions can be used in  multi-threading  applications,  with
+       the  proviso  that  the  memory  management  functions  pointed  to  by
+       pcre_malloc, pcre_free, pcre_stack_malloc, and pcre_stack_free, and the
+       callout function pointed to by pcre_callout, are shared by all threads.
+
+       The  compiled form of a regular expression is not altered during match-
+       ing, so the same compiled pattern can safely be used by several threads
+       at once.
+
+
+SAVING PRECOMPILED PATTERNS FOR LATER USE
+
+       The compiled form of a regular expression can be saved and re-used at a
+       later time, possibly by a different program, and even on a  host  other
+       than  the  one  on  which  it  was  compiled.  Details are given in the
+       pcreprecompile documentation. However, compiling a  regular  expression
+       with  one version of PCRE for use with a different version is not guar-
+       anteed to work and may cause crashes.
+
+
+CHECKING BUILD-TIME OPTIONS
+
+       int pcre_config(int what, void *where);
+
+       The function pcre_config() makes it possible for a PCRE client to  dis-
+       cover which optional features have been compiled into the PCRE library.
+       The pcrebuild documentation has more details about these optional  fea-
+       tures.
+
+       The  first  argument  for pcre_config() is an integer, specifying which
+       information is required; the second argument is a pointer to a variable
+       into  which  the  information  is  placed. The following information is
+       available:
+
+         PCRE_CONFIG_UTF8
+
+       The output is an integer that is set to one if UTF-8 support is  avail-
+       able; otherwise it is set to zero.
+
+         PCRE_CONFIG_UNICODE_PROPERTIES
+
+       The  output  is  an  integer  that is set to one if support for Unicode
+       character properties is available; otherwise it is set to zero.
+
+         PCRE_CONFIG_NEWLINE
+
+       The output is an integer whose value specifies  the  default  character
+       sequence  that is recognized as meaning "newline". The four values that
+       are supported are: 10 for LF, 13 for CR, 3338 for CRLF, -2 for ANYCRLF,
+       and  -1  for  ANY.  Though they are derived from ASCII, the same values
+       are returned in EBCDIC environments. The default should normally corre-
+       spond to the standard sequence for your operating system.
+
+         PCRE_CONFIG_BSR
+
+       The output is an integer whose value indicates what character sequences
+       the \R escape sequence matches by default. A value of 0 means  that  \R
+       matches  any  Unicode  line ending sequence; a value of 1 means that \R
+       matches only CR, LF, or CRLF. The default can be overridden when a pat-
+       tern is compiled or matched.
+
+         PCRE_CONFIG_LINK_SIZE
+
+       The  output  is  an  integer that contains the number of bytes used for
+       internal linkage in compiled regular expressions. The value is 2, 3, or
+       4.  Larger  values  allow larger regular expressions to be compiled, at
+       the expense of slower matching. The default value of  2  is  sufficient
+       for  all  but  the  most massive patterns, since it allows the compiled
+       pattern to be up to 64K in size.
+
+         PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
+
+       The output is an integer that contains the threshold  above  which  the
+       POSIX  interface  uses malloc() for output vectors. Further details are
+       given in the pcreposix documentation.
+
+         PCRE_CONFIG_MATCH_LIMIT
+
+       The output is a long integer that gives the default limit for the  num-
+       ber  of  internal  matching  function calls in a pcre_exec() execution.
+       Further details are given with pcre_exec() below.
+
+         PCRE_CONFIG_MATCH_LIMIT_RECURSION
+
+       The output is a long integer that gives the default limit for the depth
+       of   recursion  when  calling  the  internal  matching  function  in  a
+       pcre_exec() execution.  Further  details  are  given  with  pcre_exec()
+       below.
+
+         PCRE_CONFIG_STACKRECURSE
+
+       The  output is an integer that is set to one if internal recursion when
+       running pcre_exec() is implemented by recursive function calls that use
+       the  stack  to remember their state. This is the usual way that PCRE is
+       compiled. The output is zero if PCRE was compiled to use blocks of data
+       on  the  heap  instead  of  recursive  function  calls.  In  this case,
+       pcre_stack_malloc and  pcre_stack_free  are  called  to  manage  memory
+       blocks on the heap, thus avoiding the use of the stack.
+
+
+COMPILING A PATTERN
+
+       pcre *pcre_compile(const char *pattern, int options,
+            const char **errptr, int *erroffset,
+            const unsigned char *tableptr);
+
+       pcre *pcre_compile2(const char *pattern, int options,
+            int *errorcodeptr,
+            const char **errptr, int *erroffset,
+            const unsigned char *tableptr);
+
+       Either of the functions pcre_compile() or pcre_compile2() can be called
+       to compile a pattern into an internal form. The only difference between
+       the  two interfaces is that pcre_compile2() has an additional argument,
+       errorcodeptr, via which a numerical error  code  can  be  returned.  To
+       avoid  too  much repetition, we refer just to pcre_compile() below, but
+       the information applies equally to pcre_compile2().
+
+       The pattern is a C string terminated by a binary zero, and is passed in
+       the  pattern  argument.  A  pointer to a single block of memory that is
+       obtained via pcre_malloc is returned. This contains the  compiled  code
+       and related data. The pcre type is defined for the returned block; this
+       is a typedef for a structure whose contents are not externally defined.
+       It is up to the caller to free the memory (via pcre_free) when it is no
+       longer required.
+
+       Although the compiled code of a PCRE regex is relocatable, that is,  it
+       does not depend on memory location, the complete pcre data block is not
+       fully relocatable, because it may contain a copy of the tableptr  argu-
+       ment, which is an address (see below).
+
+       The options argument contains various bit settings that affect the com-
+       pilation. It should be zero if no options are required.  The  available
+       options  are  described  below. Some of them (in particular, those that
+       are compatible with Perl, but some others as well) can also be set  and
+       unset  from  within  the  pattern  (see the detailed description in the
+       pcrepattern documentation). For those options that can be different  in
+       different  parts  of  the pattern, the contents of the options argument
+       specifies their settings at the start of compilation and execution. The
+       PCRE_ANCHORED, PCRE_BSR_xxx, and PCRE_NEWLINE_xxx options can be set at
+       the time of matching as well as at compile time.
+
+       If errptr is NULL, pcre_compile() returns NULL immediately.  Otherwise,
+       if  compilation  of  a  pattern fails, pcre_compile() returns NULL, and
+       sets the variable pointed to by errptr to point to a textual error mes-
+       sage. This is a static string that is part of the library. You must not
+       try to free it. The byte offset from the start of the  pattern  to  the
+       character  that  was  being  processed when the error was discovered is
+       placed in the variable pointed to by erroffset, which must not be NULL.
+       If  it  is,  an  immediate error is given. Some errors are not detected
+       until checks are carried out when the whole pattern has  been  scanned;
+       in this case the offset is set to the end of the pattern.
+
+       If  pcre_compile2()  is  used instead of pcre_compile(), and the error-
+       codeptr argument is not NULL, a non-zero error code number is  returned
+       via  this argument in the event of an error. This is in addition to the
+       textual error message. Error codes and messages are listed below.
+
+       If the final argument, tableptr, is NULL, PCRE uses a  default  set  of
+       character  tables  that  are  built  when  PCRE  is compiled, using the
+       default C locale. Otherwise, tableptr must be an address  that  is  the
+       result  of  a  call to pcre_maketables(). This value is stored with the
+       compiled pattern, and used again by pcre_exec(), unless  another  table
+       pointer is passed to it. For more discussion, see the section on locale
+       support below.
+
+       This code fragment shows a typical straightforward  call  to  pcre_com-
+       pile():
+
+         pcre *re;
+         const char *error;
+         int erroffset;
+         re = pcre_compile(
+           "^A.*Z",          /* the pattern */
+           0,                /* default options */
+           &error,           /* for error message */
+           &erroffset,       /* for error offset */
+           NULL);            /* use default character tables */
+
+       The  following  names  for option bits are defined in the pcre.h header
+       file:
+
+         PCRE_ANCHORED
+
+       If this bit is set, the pattern is forced to be "anchored", that is, it
+       is  constrained to match only at the first matching point in the string
+       that is being searched (the "subject string"). This effect can also  be
+       achieved  by appropriate constructs in the pattern itself, which is the
+       only way to do it in Perl.
+
+         PCRE_AUTO_CALLOUT
+
+       If this bit is set, pcre_compile() automatically inserts callout items,
+       all  with  number  255, before each pattern item. For discussion of the
+       callout facility, see the pcrecallout documentation.
+
+         PCRE_BSR_ANYCRLF
+         PCRE_BSR_UNICODE
+
+       These options (which are mutually exclusive) control what the \R escape
+       sequence  matches.  The choice is either to match only CR, LF, or CRLF,
+       or to match any Unicode newline sequence. The default is specified when
+       PCRE is built. It can be overridden from within the pattern, or by set-
+       ting an option when a compiled pattern is matched.
+
+         PCRE_CASELESS
+
+       If this bit is set, letters in the pattern match both upper  and  lower
+       case  letters.  It  is  equivalent  to  Perl's /i option, and it can be
+       changed within a pattern by a (?i) option setting. In UTF-8 mode,  PCRE
+       always  understands the concept of case for characters whose values are
+       less than 128, so caseless matching is always possible. For  characters
+       with  higher  values,  the concept of case is supported if PCRE is com-
+       piled with Unicode property support, but not otherwise. If you want  to
+       use  caseless  matching  for  characters 128 and above, you must ensure
+       that PCRE is compiled with Unicode property support  as  well  as  with
+       UTF-8 support.
+
+         PCRE_DOLLAR_ENDONLY
+
+       If  this bit is set, a dollar metacharacter in the pattern matches only
+       at the end of the subject string. Without this option,  a  dollar  also
+       matches  immediately before a newline at the end of the string (but not
+       before any other newlines). The PCRE_DOLLAR_ENDONLY option  is  ignored
+       if  PCRE_MULTILINE  is  set.   There is no equivalent to this option in
+       Perl, and no way to set it within a pattern.
+
+         PCRE_DOTALL
+
+       If this bit is set, a dot metacharater in the pattern matches all char-
+       acters,  including  those that indicate newline. Without it, a dot does
+       not match when the current position is at a  newline.  This  option  is
+       equivalent  to Perl's /s option, and it can be changed within a pattern
+       by a (?s) option setting. A negative class such as [^a] always  matches
+       newline characters, independent of the setting of this option.
+
+         PCRE_DUPNAMES
+
+       If  this  bit is set, names used to identify capturing subpatterns need
+       not be unique. This can be helpful for certain types of pattern when it
+       is  known  that  only  one instance of the named subpattern can ever be
+       matched. There are more details of named subpatterns  below;  see  also
+       the pcrepattern documentation.
+
+         PCRE_EXTENDED
+
+       If  this  bit  is  set,  whitespace  data characters in the pattern are
+       totally ignored except when escaped or inside a character class. White-
+       space does not include the VT character (code 11). In addition, charac-
+       ters between an unescaped # outside a character class and the next new-
+       line,  inclusive,  are  also  ignored.  This is equivalent to Perl's /x
+       option, and it can be changed within a pattern by a  (?x)  option  set-
+       ting.
+
+       This  option  makes  it possible to include comments inside complicated
+       patterns.  Note, however, that this applies only  to  data  characters.
+       Whitespace   characters  may  never  appear  within  special  character
+       sequences in a pattern, for  example  within  the  sequence  (?(  which
+       introduces a conditional subpattern.
+
+         PCRE_EXTRA
+
+       This  option  was invented in order to turn on additional functionality
+       of PCRE that is incompatible with Perl, but it  is  currently  of  very
+       little  use. When set, any backslash in a pattern that is followed by a
+       letter that has no special meaning  causes  an  error,  thus  reserving
+       these  combinations  for  future  expansion.  By default, as in Perl, a
+       backslash followed by a letter with no special meaning is treated as  a
+       literal.  (Perl can, however, be persuaded to give a warning for this.)
+       There are at present no other features controlled by  this  option.  It
+       can also be set by a (?X) option setting within a pattern.
+
+         PCRE_FIRSTLINE
+
+       If  this  option  is  set,  an  unanchored pattern is required to match
+       before or at the first  newline  in  the  subject  string,  though  the
+       matched text may continue over the newline.
+
+         PCRE_JAVASCRIPT_COMPAT
+
+       If this option is set, PCRE's behaviour is changed in some ways so that
+       it is compatible with JavaScript rather than Perl. The changes  are  as
+       follows:
+
+       (1)  A  lone  closing square bracket in a pattern causes a compile-time
+       error, because this is illegal in JavaScript (by default it is  treated
+       as a data character). Thus, the pattern AB]CD becomes illegal when this
+       option is set.
+
+       (2) At run time, a back reference to an unset subpattern group  matches
+       an  empty  string (by default this causes the current matching alterna-
+       tive to fail). A pattern such as (\1)(a) succeeds when this  option  is
+       set  (assuming  it can find an "a" in the subject), whereas it fails by
+       default, for Perl compatibility.
+
+         PCRE_MULTILINE
+
+       By default, PCRE treats the subject string as consisting  of  a  single
+       line  of characters (even if it actually contains newlines). The "start
+       of line" metacharacter (^) matches only at the  start  of  the  string,
+       while  the  "end  of line" metacharacter ($) matches only at the end of
+       the string, or before a terminating newline (unless PCRE_DOLLAR_ENDONLY
+       is set). This is the same as Perl.
+
+       When  PCRE_MULTILINE  it  is set, the "start of line" and "end of line"
+       constructs match immediately following or immediately  before  internal
+       newlines  in  the  subject string, respectively, as well as at the very
+       start and end. This is equivalent to Perl's /m option, and  it  can  be
+       changed within a pattern by a (?m) option setting. If there are no new-
+       lines in a subject string, or no occurrences of ^ or $  in  a  pattern,
+       setting PCRE_MULTILINE has no effect.
+
+         PCRE_NEWLINE_CR
+         PCRE_NEWLINE_LF
+         PCRE_NEWLINE_CRLF
+         PCRE_NEWLINE_ANYCRLF
+         PCRE_NEWLINE_ANY
+
+       These  options  override the default newline definition that was chosen
+       when PCRE was built. Setting the first or the second specifies  that  a
+       newline  is  indicated  by a single character (CR or LF, respectively).
+       Setting PCRE_NEWLINE_CRLF specifies that a newline is indicated by  the
+       two-character  CRLF  sequence.  Setting  PCRE_NEWLINE_ANYCRLF specifies
+       that any of the three preceding sequences should be recognized. Setting
+       PCRE_NEWLINE_ANY  specifies that any Unicode newline sequence should be
+       recognized. The Unicode newline sequences are the three just mentioned,
+       plus  the  single  characters  VT (vertical tab, U+000B), FF (formfeed,
+       U+000C), NEL (next line, U+0085), LS (line separator, U+2028),  and  PS
+       (paragraph  separator,  U+2029).  The  last  two are recognized only in
+       UTF-8 mode.
+
+       The newline setting in the  options  word  uses  three  bits  that  are
+       treated as a number, giving eight possibilities. Currently only six are
+       used (default plus the five values above). This means that if  you  set
+       more  than one newline option, the combination may or may not be sensi-
+       ble. For example, PCRE_NEWLINE_CR with PCRE_NEWLINE_LF is equivalent to
+       PCRE_NEWLINE_CRLF,  but other combinations may yield unused numbers and
+       cause an error.
+
+       The only time that a line break is specially recognized when  compiling
+       a  pattern  is  if  PCRE_EXTENDED  is set, and an unescaped # outside a
+       character class is encountered. This indicates  a  comment  that  lasts
+       until  after the next line break sequence. In other circumstances, line
+       break  sequences  are  treated  as  literal  data,   except   that   in
+       PCRE_EXTENDED mode, both CR and LF are treated as whitespace characters
+       and are therefore ignored.
+
+       The newline option that is set at compile time becomes the default that
+       is used for pcre_exec() and pcre_dfa_exec(), but it can be overridden.
+
+         PCRE_NO_AUTO_CAPTURE
+
+       If this option is set, it disables the use of numbered capturing paren-
+       theses in the pattern. Any opening parenthesis that is not followed  by
+       ?  behaves as if it were followed by ?: but named parentheses can still
+       be used for capturing (and they acquire  numbers  in  the  usual  way).
+       There is no equivalent of this option in Perl.
+
+         PCRE_UNGREEDY
+
+       This  option  inverts  the "greediness" of the quantifiers so that they
+       are not greedy by default, but become greedy if followed by "?". It  is
+       not  compatible  with Perl. It can also be set by a (?U) option setting
+       within the pattern.
+
+         PCRE_UTF8
+
+       This option causes PCRE to regard both the pattern and the  subject  as
+       strings  of  UTF-8 characters instead of single-byte character strings.
+       However, it is available only when PCRE is built to include UTF-8  sup-
+       port.  If not, the use of this option provokes an error. Details of how
+       this option changes the behaviour of PCRE are given in the  section  on
+       UTF-8 support in the main pcre page.
+
+         PCRE_NO_UTF8_CHECK
+
+       When PCRE_UTF8 is set, the validity of the pattern as a UTF-8 string is
+       automatically checked. There is a  discussion  about  the  validity  of
+       UTF-8  strings  in  the main pcre page. If an invalid UTF-8 sequence of
+       bytes is found, pcre_compile() returns an error. If  you  already  know
+       that your pattern is valid, and you want to skip this check for perfor-
+       mance reasons, you can set the PCRE_NO_UTF8_CHECK option.  When  it  is
+       set,  the  effect  of  passing  an invalid UTF-8 string as a pattern is
+       undefined. It may cause your program to crash. Note  that  this  option
+       can  also be passed to pcre_exec() and pcre_dfa_exec(), to suppress the
+       UTF-8 validity checking of subject strings.
+
+
+COMPILATION ERROR CODES
+
+       The following table lists the error  codes  than  may  be  returned  by
+       pcre_compile2(),  along with the error messages that may be returned by
+       both compiling functions. As PCRE has developed, some error codes  have
+       fallen out of use. To avoid confusion, they have not been re-used.

+
+STUDYING A PATTERN
+
+       pcre_extra *pcre_study(const pcre *code, int options
+            const char **errptr);
+
+       If  a  compiled  pattern is going to be used several times, it is worth
+       spending more time analyzing it in order to speed up the time taken for
+       matching.  The function pcre_study() takes a pointer to a compiled pat-
+       tern as its first argument. If studying the pattern produces additional
+       information  that  will  help speed up matching, pcre_study() returns a
+       pointer to a pcre_extra block, in which the study_data field points  to
+       the results of the study.
+
+       The  returned  value  from  pcre_study()  can  be  passed  directly  to
+       pcre_exec() or pcre_dfa_exec(). However, a pcre_extra block  also  con-
+       tains  other  fields  that can be set by the caller before the block is
+       passed; these are described below in the section on matching a pattern.
+
+       If studying the  pattern  does  not  produce  any  useful  information,
+       pcre_study() returns NULL. In that circumstance, if the calling program
+       wants  to  pass  any  of   the   other   fields   to   pcre_exec()   or
+       pcre_dfa_exec(), it must set up its own pcre_extra block.
+
+       The  second  argument of pcre_study() contains option bits. At present,
+       no options are defined, and this argument should always be zero.
+
+       The third argument for pcre_study() is a pointer for an error  message.
+       If  studying  succeeds  (even  if no data is returned), the variable it
+       points to is set to NULL. Otherwise it is set to  point  to  a  textual
+       error message. This is a static string that is part of the library. You
+       must not try to free it. You should test the  error  pointer  for  NULL
+       after calling pcre_study(), to be sure that it has run successfully.
+
+       This is a typical call to pcre_study():
+
+         pcre_extra *pe;
+         pe = pcre_study(
+           re,             /* result of pcre_compile() */
+           0,              /* no options exist */
+           &error);        /* set to NULL or points to a message */
+
+       Studying a pattern does two things: first, a lower bound for the length
+       of subject string that is needed to match the pattern is computed. This
+       does not mean that there are any strings of that length that match, but
+       it does guarantee that no shorter strings match. The value is  used  by
+       pcre_exec()  and  pcre_dfa_exec()  to  avoid  wasting time by trying to
+       match strings that are shorter than the lower bound. You can  find  out
+       the value in a calling program via the pcre_fullinfo() function.
+
+       Studying a pattern is also useful for non-anchored patterns that do not
+       have a single fixed starting character. A bitmap of  possible  starting
+       bytes  is  created. This speeds up finding a position in the subject at
+       which to start matching.
+
+
+LOCALE SUPPORT
+
+       PCRE handles caseless matching, and determines whether  characters  are
+       letters,  digits, or whatever, by reference to a set of tables, indexed
+       by character value. When running in UTF-8 mode, this  applies  only  to
+       characters  with  codes  less than 128. Higher-valued codes never match
+       escapes such as \w or \d, but can be tested with \p if  PCRE  is  built
+       with  Unicode  character property support. The use of locales with Uni-
+       code is discouraged. If you are handling characters with codes  greater
+       than  128, you should either use UTF-8 and Unicode, or use locales, but
+       not try to mix the two.
+
+       PCRE contains an internal set of tables that are used  when  the  final
+       argument  of  pcre_compile()  is  NULL.  These  are sufficient for many
+       applications.  Normally, the internal tables recognize only ASCII char-
+       acters. However, when PCRE is built, it is possible to cause the inter-
+       nal tables to be rebuilt in the default "C" locale of the local system,
+       which may cause them to be different.
+
+       The  internal tables can always be overridden by tables supplied by the
+       application that calls PCRE. These may be created in a different locale
+       from  the  default.  As more and more applications change to using Uni-
+       code, the need for this locale support is expected to die away.
+
+       External tables are built by calling  the  pcre_maketables()  function,
+       which  has no arguments, in the relevant locale. The result can then be
+       passed to pcre_compile() or pcre_exec()  as  often  as  necessary.  For
+       example,  to  build  and use tables that are appropriate for the French
+       locale (where accented characters with  values  greater  than  128  are
+       treated as letters), the following code could be used:
+
+         setlocale(LC_CTYPE, "fr_FR");
+         tables = pcre_maketables();
+         re = pcre_compile(..., tables);
+
+       The  locale  name "fr_FR" is used on Linux and other Unix-like systems;
+       if you are using Windows, the name for the French locale is "french".
+
+       When pcre_maketables() runs, the tables are built  in  memory  that  is
+       obtained  via  pcre_malloc. It is the caller's responsibility to ensure
+       that the memory containing the tables remains available for as long  as
+       it is needed.
+
+       The pointer that is passed to pcre_compile() is saved with the compiled
+       pattern, and the same tables are used via this pointer by  pcre_study()
+       and normally also by pcre_exec(). Thus, by default, for any single pat-
+       tern, compilation, studying and matching all happen in the same locale,
+       but different patterns can be compiled in different locales.
+
+       It  is  possible to pass a table pointer or NULL (indicating the use of
+       the internal tables) to pcre_exec(). Although  not  intended  for  this
+       purpose,  this facility could be used to match a pattern in a different
+       locale from the one in which it was compiled. Passing table pointers at
+       run time is discussed below in the section on matching a pattern.
+
+
+INFORMATION ABOUT A PATTERN
+
+       int pcre_fullinfo(const pcre *code, const pcre_extra *extra,
+            int what, void *where);
+
+       The  pcre_fullinfo() function returns information about a compiled pat-
+       tern. It replaces the obsolete pcre_info() function, which is neverthe-
+       less retained for backwards compability (and is documented below).
+
+       The  first  argument  for  pcre_fullinfo() is a pointer to the compiled
+       pattern. The second argument is the result of pcre_study(), or NULL  if
+       the  pattern  was not studied. The third argument specifies which piece
+       of information is required, and the fourth argument is a pointer  to  a
+       variable  to  receive  the  data. The yield of the function is zero for
+       success, or one of the following negative numbers:
+
+         PCRE_ERROR_NULL       the argument code was NULL
+                               the argument where was NULL
+         PCRE_ERROR_BADMAGIC   the "magic number" was not found
+         PCRE_ERROR_BADOPTION  the value of what was invalid
+
+       The "magic number" is placed at the start of each compiled  pattern  as
+       an  simple check against passing an arbitrary memory pointer. Here is a
+       typical call of pcre_fullinfo(), to obtain the length of  the  compiled
+       pattern:
+
+         int rc;
+         size_t length;
+         rc = pcre_fullinfo(
+           re,               /* result of pcre_compile() */
+           pe,               /* result of pcre_study(), or NULL */
+           PCRE_INFO_SIZE,   /* what is required */
+           &length);         /* where to put the data */
+
+       The  possible  values for the third argument are defined in pcre.h, and
+       are as follows:
+
+         PCRE_INFO_BACKREFMAX
+
+       Return the number of the highest back reference  in  the  pattern.  The
+       fourth  argument  should  point to an int variable. Zero is returned if
+       there are no back references.
+
+         PCRE_INFO_CAPTURECOUNT
+
+       Return the number of capturing subpatterns in the pattern.  The  fourth
+       argument should point to an int variable.
+
+         PCRE_INFO_DEFAULT_TABLES
+
+       Return  a pointer to the internal default character tables within PCRE.
+       The fourth argument should point to an unsigned char *  variable.  This
+       information call is provided for internal use by the pcre_study() func-
+       tion. External callers can cause PCRE to use  its  internal  tables  by
+       passing a NULL table pointer.
+
+         PCRE_INFO_FIRSTBYTE
+
+       Return  information  about  the first byte of any matched string, for a
+       non-anchored pattern. The fourth argument should point to an int  vari-
+       able.  (This option used to be called PCRE_INFO_FIRSTCHAR; the old name
+       is still recognized for backwards compatibility.)
+
+       If there is a fixed first byte, for example, from  a  pattern  such  as
+       (cat|cow|coyote), its value is returned. Otherwise, if either
+
+       (a)  the pattern was compiled with the PCRE_MULTILINE option, and every
+       branch starts with "^", or
+
+       (b) every branch of the pattern starts with ".*" and PCRE_DOTALL is not
+       set (if it were set, the pattern would be anchored),
+
+       -1  is  returned, indicating that the pattern matches only at the start
+       of a subject string or after any newline within the  string.  Otherwise
+       -2 is returned. For anchored patterns, -2 is returned.
+
+         PCRE_INFO_FIRSTTABLE
+
+       If  the pattern was studied, and this resulted in the construction of a
+       256-bit table indicating a fixed set of bytes for the first byte in any
+       matching  string, a pointer to the table is returned. Otherwise NULL is
+       returned. The fourth argument should point to an unsigned char *  vari-
+       able.
+
+         PCRE_INFO_HASCRORLF
+
+       Return  1  if  the  pattern  contains any explicit matches for CR or LF
+       characters, otherwise 0. The fourth argument should  point  to  an  int
+       variable.  An explicit match is either a literal CR or LF character, or
+       \r or \n.
+
+         PCRE_INFO_JCHANGED
+
+       Return 1 if the (?J) or (?-J) option setting is used  in  the  pattern,
+       otherwise  0. The fourth argument should point to an int variable. (?J)
+       and (?-J) set and unset the local PCRE_DUPNAMES option, respectively.
+
+         PCRE_INFO_LASTLITERAL
+
+       Return the value of the rightmost literal byte that must exist  in  any
+       matched  string,  other  than  at  its  start,  if such a byte has been
+       recorded. The fourth argument should point to an int variable. If there
+       is  no such byte, -1 is returned. For anchored patterns, a last literal
+       byte is recorded only if it follows something of variable  length.  For
+       example, for the pattern /^a\d+z\d+/ the returned value is "z", but for
+       /^a\dz\d/ the returned value is -1.
+
+         PCRE_INFO_MINLENGTH
+
+       If the pattern was studied and a minimum length  for  matching  subject
+       strings  was  computed,  its  value is returned. Otherwise the returned
+       value is -1. The value is a number of characters, not bytes  (this  may
+       be  relevant in UTF-8 mode). The fourth argument should point to an int
+       variable. A non-negative value is a lower bound to the  length  of  any
+       matching  string.  There  may not be any strings of that length that do
+       actually match, but every string that does match is at least that long.
+
+         PCRE_INFO_NAMECOUNT
+         PCRE_INFO_NAMEENTRYSIZE
+         PCRE_INFO_NAMETABLE
+
+       PCRE supports the use of named as well as numbered capturing  parenthe-
+       ses.  The names are just an additional way of identifying the parenthe-
+       ses, which still acquire numbers. Several convenience functions such as
+       pcre_get_named_substring()  are  provided  for extracting captured sub-
+       strings by name. It is also possible to extract the data  directly,  by
+       first  converting  the  name to a number in order to access the correct
+       pointers in the output vector (described with pcre_exec() below). To do
+       the  conversion,  you  need  to  use  the  name-to-number map, which is
+       described by these three values.
+
+       The map consists of a number of fixed-size entries. PCRE_INFO_NAMECOUNT
+       gives the number of entries, and PCRE_INFO_NAMEENTRYSIZE gives the size
+       of each entry; both of these  return  an  int  value.  The  entry  size
+       depends  on the length of the longest name. PCRE_INFO_NAMETABLE returns
+       a pointer to the first entry of the table  (a  pointer  to  char).  The
+       first two bytes of each entry are the number of the capturing parenthe-
+       sis, most significant byte first. The rest of the entry is  the  corre-
+       sponding name, zero terminated.
+
+       The  names are in alphabetical order. Duplicate names may appear if (?|
+       is used to create multiple groups with the same number, as described in
+       the  section  on  duplicate subpattern numbers in the pcrepattern page.
+       Duplicate names for subpatterns with different  numbers  are  permitted
+       only  if  PCRE_DUPNAMES  is  set. In all cases of duplicate names, they
+       appear in the table in the order in which they were found in  the  pat-
+       tern.  In  the  absence  of (?| this is the order of increasing number;
+       when (?| is used this is not necessarily the case because later subpat-
+       terns may have lower numbers.
+
+       As  a  simple  example of the name/number table, consider the following
+       pattern (assume PCRE_EXTENDED is set, so white space -  including  new-
+       lines - is ignored):
+
+         (? (?(\d\d)?\d\d) -
+         (?\d\d) - (?\d\d) )
+
+       There  are  four  named subpatterns, so the table has four entries, and
+       each entry in the table is eight bytes long. The table is  as  follows,
+       with non-printing bytes shows in hexadecimal, and undefined bytes shown
+       as ??:
+
+         00 01 d  a  t  e  00 ??
+         00 05 d  a  y  00 ?? ??
+         00 04 m  o  n  t  h  00
+         00 02 y  e  a  r  00 ??
+
+       When writing code to extract data  from  named  subpatterns  using  the
+       name-to-number  map,  remember that the length of the entries is likely
+       to be different for each compiled pattern.
+
+         PCRE_INFO_OKPARTIAL
+
+       Return 1  if  the  pattern  can  be  used  for  partial  matching  with
+       pcre_exec(),  otherwise  0.  The fourth argument should point to an int
+       variable. From  release  8.00,  this  always  returns  1,  because  the
+       restrictions  that  previously  applied  to  partial matching have been
+       lifted. The pcrepartial documentation gives details of  partial  match-
+       ing.
+
+         PCRE_INFO_OPTIONS
+
+       Return  a  copy of the options with which the pattern was compiled. The
+       fourth argument should point to an unsigned long  int  variable.  These
+       option bits are those specified in the call to pcre_compile(), modified
+       by any top-level option settings at the start of the pattern itself. In
+       other  words,  they are the options that will be in force when matching
+       starts. For example, if the pattern /(?im)abc(?-i)d/ is  compiled  with
+       the  PCRE_EXTENDED option, the result is PCRE_CASELESS, PCRE_MULTILINE,
+       and PCRE_EXTENDED.
+
+       A pattern is automatically anchored by PCRE if  all  of  its  top-level
+       alternatives begin with one of the following:
+
+         ^     unless PCRE_MULTILINE is set
+         \A    always
+         \G    always
+         .*    if PCRE_DOTALL is set and there are no back
+                 references to the subpattern in which .* appears
+
+       For such patterns, the PCRE_ANCHORED bit is set in the options returned
+       by pcre_fullinfo().
+
+         PCRE_INFO_SIZE
+
+       Return the size of the compiled pattern, that is, the  value  that  was
+       passed as the argument to pcre_malloc() when PCRE was getting memory in
+       which to place the compiled data. The fourth argument should point to a
+       size_t variable.
+
+         PCRE_INFO_STUDYSIZE
+
+       Return the size of the data block pointed to by the study_data field in
+       a pcre_extra block. That is,  it  is  the  value  that  was  passed  to
+       pcre_malloc() when PCRE was getting memory into which to place the data
+       created by pcre_study(). If pcre_extra is NULL, or there  is  no  study
+       data,  zero  is  returned. The fourth argument should point to a size_t
+       variable.
+
+
+OBSOLETE INFO FUNCTION
+
+       int pcre_info(const pcre *code, int *optptr, int *firstcharptr);
+
+       The pcre_info() function is now obsolete because its interface  is  too
+       restrictive  to return all the available data about a compiled pattern.
+       New  programs  should  use  pcre_fullinfo()  instead.  The   yield   of
+       pcre_info()  is the number of capturing subpatterns, or one of the fol-
+       lowing negative numbers:
+
+         PCRE_ERROR_NULL       the argument code was NULL
+         PCRE_ERROR_BADMAGIC   the "magic number" was not found
+
+       If the optptr argument is not NULL, a copy of the  options  with  which
+       the  pattern  was  compiled  is placed in the integer it points to (see
+       PCRE_INFO_OPTIONS above).
+
+       If the pattern is not anchored and the  firstcharptr  argument  is  not
+       NULL,  it is used to pass back information about the first character of
+       any matched string (see PCRE_INFO_FIRSTBYTE above).
+
+
+REFERENCE COUNTS
+
+       int pcre_refcount(pcre *code, int adjust);
+
+       The pcre_refcount() function is used to maintain a reference  count  in
+       the data block that contains a compiled pattern. It is provided for the
+       benefit of applications that  operate  in  an  object-oriented  manner,
+       where different parts of the application may be using the same compiled
+       pattern, but you want to free the block when they are all done.
+
+       When a pattern is compiled, the reference count field is initialized to
+       zero.   It is changed only by calling this function, whose action is to
+       add the adjust value (which may be positive or  negative)  to  it.  The
+       yield of the function is the new value. However, the value of the count
+       is constrained to lie between 0 and 65535, inclusive. If the new  value
+       is outside these limits, it is forced to the appropriate limit value.
+
+       Except  when it is zero, the reference count is not correctly preserved
+       if a pattern is compiled on one host and then  transferred  to  a  host
+       whose byte-order is different. (This seems a highly unlikely scenario.)
+
+
+MATCHING A PATTERN: THE TRADITIONAL FUNCTION
+
+       int pcre_exec(const pcre *code, const pcre_extra *extra,
+            const char *subject, int length, int startoffset,
+            int options, int *ovector, int ovecsize);
+
+       The  function pcre_exec() is called to match a subject string against a
+       compiled pattern, which is passed in the code argument. If the  pattern
+       was  studied,  the  result  of  the study should be passed in the extra
+       argument. This function is the main matching facility of  the  library,
+       and it operates in a Perl-like manner. For specialist use there is also
+       an alternative matching function, which is described below in the  sec-
+       tion about the pcre_dfa_exec() function.
+
+       In  most applications, the pattern will have been compiled (and option-
+       ally studied) in the same process that calls pcre_exec().  However,  it
+       is possible to save compiled patterns and study data, and then use them
+       later in different processes, possibly even on different hosts.  For  a
+       discussion about this, see the pcreprecompile documentation.
+
+       Here is an example of a simple call to pcre_exec():
+
+         int rc;
+         int ovector[30];
+         rc = pcre_exec(
+           re,             /* result of pcre_compile() */
+           NULL,           /* we didn't study the pattern */
+           "some string",  /* the subject string */
+           11,             /* the length of the subject string */
+           0,              /* start at offset 0 in the subject */
+           0,              /* default options */
+           ovector,        /* vector of integers for substring information */
+           30);            /* number of elements (NOT size in bytes) */
+
+   Extra data for pcre_exec()
+
+       If  the  extra argument is not NULL, it must point to a pcre_extra data
+       block. The pcre_study() function returns such a block (when it  doesn't
+       return  NULL), but you can also create one for yourself, and pass addi-
+       tional information in it. The pcre_extra block contains  the  following
+       fields (not necessarily in this order):
+
+         unsigned long int flags;
+         void *study_data;
+         unsigned long int match_limit;
+         unsigned long int match_limit_recursion;
+         void *callout_data;
+         const unsigned char *tables;
+
+       The  flags  field  is a bitmap that specifies which of the other fields
+       are set. The flag bits are:
+
+         PCRE_EXTRA_STUDY_DATA
+         PCRE_EXTRA_MATCH_LIMIT
+         PCRE_EXTRA_MATCH_LIMIT_RECURSION
+         PCRE_EXTRA_CALLOUT_DATA
+         PCRE_EXTRA_TABLES
+
+       Other flag bits should be set to zero. The study_data field is  set  in
+       the  pcre_extra  block  that is returned by pcre_study(), together with
+       the appropriate flag bit. You should not set this yourself, but you may
+       add  to  the  block by setting the other fields and their corresponding
+       flag bits.
+
+       The match_limit field provides a means of preventing PCRE from using up
+       a  vast amount of resources when running patterns that are not going to
+       match, but which have a very large number  of  possibilities  in  their
+       search  trees. The classic example is a pattern that uses nested unlim-
+       ited repeats.
+
+       Internally, PCRE uses a function called match() which it calls  repeat-
+       edly  (sometimes  recursively). The limit set by match_limit is imposed
+       on the number of times this function is called during  a  match,  which
+       has  the  effect  of  limiting the amount of backtracking that can take
+       place. For patterns that are not anchored, the count restarts from zero
+       for each position in the subject string.
+
+       The  default  value  for  the  limit can be set when PCRE is built; the
+       default default is 10 million, which handles all but the  most  extreme
+       cases.  You  can  override  the  default by suppling pcre_exec() with a
+       pcre_extra    block    in    which    match_limit    is    set,     and
+       PCRE_EXTRA_MATCH_LIMIT  is  set  in  the  flags  field. If the limit is
+       exceeded, pcre_exec() returns PCRE_ERROR_MATCHLIMIT.
+
+       The match_limit_recursion field is similar to match_limit, but  instead
+       of limiting the total number of times that match() is called, it limits
+       the depth of recursion. The recursion depth is a  smaller  number  than
+       the  total number of calls, because not all calls to match() are recur-
+       sive.  This limit is of use only if it is set smaller than match_limit.
+
+       Limiting the recursion depth limits the amount of  stack  that  can  be
+       used, or, when PCRE has been compiled to use memory on the heap instead
+       of the stack, the amount of heap memory that can be used.
+
+       The default value for match_limit_recursion can be  set  when  PCRE  is
+       built;  the  default  default  is  the  same  value  as the default for
+       match_limit. You can override the default by suppling pcre_exec()  with
+       a   pcre_extra   block  in  which  match_limit_recursion  is  set,  and
+       PCRE_EXTRA_MATCH_LIMIT_RECURSION is set in  the  flags  field.  If  the
+       limit is exceeded, pcre_exec() returns PCRE_ERROR_RECURSIONLIMIT.
+
+       The  callout_data  field is used in conjunction with the "callout" fea-
+       ture, and is described in the pcrecallout documentation.
+
+       The tables field  is  used  to  pass  a  character  tables  pointer  to
+       pcre_exec();  this overrides the value that is stored with the compiled
+       pattern. A non-NULL value is stored with the compiled pattern  only  if
+       custom  tables  were  supplied to pcre_compile() via its tableptr argu-
+       ment.  If NULL is passed to pcre_exec() using this mechanism, it forces
+       PCRE's  internal  tables  to be used. This facility is helpful when re-
+       using patterns that have been saved after compiling  with  an  external
+       set  of  tables,  because  the  external tables might be at a different
+       address when pcre_exec() is called. See the  pcreprecompile  documenta-
+       tion for a discussion of saving compiled patterns for later use.
+
+   Option bits for pcre_exec()
+
+       The  unused  bits of the options argument for pcre_exec() must be zero.
+       The only bits that may  be  set  are  PCRE_ANCHORED,  PCRE_NEWLINE_xxx,
+       PCRE_NOTBOL,    PCRE_NOTEOL,    PCRE_NOTEMPTY,   PCRE_NOTEMPTY_ATSTART,
+       PCRE_NO_START_OPTIMIZE,  PCRE_NO_UTF8_CHECK,   PCRE_PARTIAL_SOFT,   and
+       PCRE_PARTIAL_HARD.
+
+         PCRE_ANCHORED
+
+       The  PCRE_ANCHORED  option  limits pcre_exec() to matching at the first
+       matching position. If a pattern was  compiled  with  PCRE_ANCHORED,  or
+       turned  out to be anchored by virtue of its contents, it cannot be made
+       unachored at matching time.
+
+         PCRE_BSR_ANYCRLF
+         PCRE_BSR_UNICODE
+
+       These options (which are mutually exclusive) control what the \R escape
+       sequence  matches.  The choice is either to match only CR, LF, or CRLF,
+       or to match any Unicode newline sequence. These  options  override  the
+       choice that was made or defaulted when the pattern was compiled.
+
+         PCRE_NEWLINE_CR
+         PCRE_NEWLINE_LF
+         PCRE_NEWLINE_CRLF
+         PCRE_NEWLINE_ANYCRLF
+         PCRE_NEWLINE_ANY
+
+       These  options  override  the  newline  definition  that  was chosen or
+       defaulted when the pattern was compiled. For details, see the  descrip-
+       tion  of  pcre_compile()  above.  During  matching,  the newline choice
+       affects the behaviour of the dot, circumflex,  and  dollar  metacharac-
+       ters.  It may also alter the way the match position is advanced after a
+       match failure for an unanchored pattern.
+
+       When PCRE_NEWLINE_CRLF, PCRE_NEWLINE_ANYCRLF,  or  PCRE_NEWLINE_ANY  is
+       set,  and a match attempt for an unanchored pattern fails when the cur-
+       rent position is at a  CRLF  sequence,  and  the  pattern  contains  no
+       explicit  matches  for  CR  or  LF  characters,  the  match position is
+       advanced by two characters instead of one, in other words, to after the
+       CRLF.
+
+       The above rule is a compromise that makes the most common cases work as
+       expected. For example, if the  pattern  is  .+A  (and  the  PCRE_DOTALL
+       option is not set), it does not match the string "\r\nA" because, after
+       failing at the start, it skips both the CR and the LF before  retrying.
+       However,  the  pattern  [\r\n]A does match that string, because it con-
+       tains an explicit CR or LF reference, and so advances only by one char-
+       acter after the first failure.
+
+       An explicit match for CR of LF is either a literal appearance of one of
+       those characters, or one of the \r or  \n  escape  sequences.  Implicit
+       matches  such  as [^X] do not count, nor does \s (which includes CR and
+       LF in the characters that it matches).
+
+       Notwithstanding the above, anomalous effects may still occur when  CRLF
+       is a valid newline sequence and explicit \r or \n escapes appear in the
+       pattern.
+
+         PCRE_NOTBOL
+
+       This option specifies that first character of the subject string is not
+       the  beginning  of  a  line, so the circumflex metacharacter should not
+       match before it. Setting this without PCRE_MULTILINE (at compile  time)
+       causes  circumflex  never to match. This option affects only the behav-
+       iour of the circumflex metacharacter. It does not affect \A.
+
+         PCRE_NOTEOL
+
+       This option specifies that the end of the subject string is not the end
+       of  a line, so the dollar metacharacter should not match it nor (except
+       in multiline mode) a newline immediately before it. Setting this  with-
+       out PCRE_MULTILINE (at compile time) causes dollar never to match. This
+       option affects only the behaviour of the dollar metacharacter. It  does
+       not affect \Z or \z.
+
+         PCRE_NOTEMPTY
+
+       An empty string is not considered to be a valid match if this option is
+       set. If there are alternatives in the pattern, they are tried.  If  all
+       the  alternatives  match  the empty string, the entire match fails. For
+       example, if the pattern
+
+         a?b?
+
+       is applied to a string not beginning with "a" or  "b",  it  matches  an
+       empty  string at the start of the subject. With PCRE_NOTEMPTY set, this
+       match is not valid, so PCRE searches further into the string for occur-
+       rences of "a" or "b".
+
+         PCRE_NOTEMPTY_ATSTART
+
+       This  is  like PCRE_NOTEMPTY, except that an empty string match that is
+       not at the start of  the  subject  is  permitted.  If  the  pattern  is
+       anchored, such a match can occur only if the pattern contains \K.
+
+       Perl     has    no    direct    equivalent    of    PCRE_NOTEMPTY    or
+       PCRE_NOTEMPTY_ATSTART, but it does make a special  case  of  a  pattern
+       match  of  the empty string within its split() function, and when using
+       the /g modifier. It is  possible  to  emulate  Perl's  behaviour  after
+       matching a null string by first trying the match again at the same off-
+       set with PCRE_NOTEMPTY_ATSTART and  PCRE_ANCHORED,  and  then  if  that
+       fails, by advancing the starting offset (see below) and trying an ordi-
+       nary match again. There is some code that demonstrates how to  do  this
+       in the pcredemo sample program.
+
+         PCRE_NO_START_OPTIMIZE
+
+       There  are a number of optimizations that pcre_exec() uses at the start
+       of a match, in order to speed up the process. For  example,  if  it  is
+       known  that  a  match must start with a specific character, it searches
+       the subject for that character, and fails immediately if it cannot find
+       it,  without actually running the main matching function. When callouts
+       are in use, these optimizations can cause  them  to  be  skipped.  This
+       option  disables  the  "start-up" optimizations, causing performance to
+       suffer, but ensuring that the callouts do occur.
+
+         PCRE_NO_UTF8_CHECK
+
+       When PCRE_UTF8 is set at compile time, the validity of the subject as a
+       UTF-8  string is automatically checked when pcre_exec() is subsequently
+       called.  The value of startoffset is also checked  to  ensure  that  it
+       points  to  the start of a UTF-8 character. There is a discussion about
+       the validity of UTF-8 strings in the section on UTF-8  support  in  the
+       main  pcre  page.  If  an  invalid  UTF-8  sequence  of bytes is found,
+       pcre_exec() returns the error PCRE_ERROR_BADUTF8. If  startoffset  con-
+       tains an invalid value, PCRE_ERROR_BADUTF8_OFFSET is returned.
+
+       If  you  already  know that your subject is valid, and you want to skip
+       these   checks   for   performance   reasons,   you   can    set    the
+       PCRE_NO_UTF8_CHECK  option  when calling pcre_exec(). You might want to
+       do this for the second and subsequent calls to pcre_exec() if  you  are
+       making  repeated  calls  to  find  all  the matches in a single subject
+       string. However, you should be  sure  that  the  value  of  startoffset
+       points  to  the  start of a UTF-8 character. When PCRE_NO_UTF8_CHECK is
+       set, the effect of passing an invalid UTF-8 string as a subject,  or  a
+       value  of startoffset that does not point to the start of a UTF-8 char-
+       acter, is undefined. Your program may crash.
+
+         PCRE_PARTIAL_HARD
+         PCRE_PARTIAL_SOFT
+
+       These options turn on the partial matching feature. For backwards  com-
+       patibility,  PCRE_PARTIAL is a synonym for PCRE_PARTIAL_SOFT. A partial
+       match occurs if the end of the subject string is reached  successfully,
+       but  there  are not enough subject characters to complete the match. If
+       this happens when PCRE_PARTIAL_HARD  is  set,  pcre_exec()  immediately
+       returns  PCRE_ERROR_PARTIAL.  Otherwise,  if  PCRE_PARTIAL_SOFT is set,
+       matching continues by testing any other alternatives. Only if they  all
+       fail  is  PCRE_ERROR_PARTIAL  returned (instead of PCRE_ERROR_NOMATCH).
+       The portion of the string that was inspected when the partial match was
+       found  is  set  as  the first matching string. There is a more detailed
+       discussion in the pcrepartial documentation.
+
+   The string to be matched by pcre_exec()
+
+       The subject string is passed to pcre_exec() as a pointer in subject,  a
+       length (in bytes) in length, and a starting byte offset in startoffset.
+       In UTF-8 mode, the byte offset must point to the start of a UTF-8 char-
+       acter.  Unlike  the pattern string, the subject may contain binary zero
+       bytes. When the starting offset is zero, the search for a match  starts
+       at  the  beginning  of  the subject, and this is by far the most common
+       case.
+
+       A non-zero starting offset is useful when searching for  another  match
+       in  the same subject by calling pcre_exec() again after a previous suc-
+       cess.  Setting startoffset differs from just passing over  a  shortened
+       string  and  setting  PCRE_NOTBOL  in the case of a pattern that begins
+       with any kind of lookbehind. For example, consider the pattern
+
+         \Biss\B
+
+       which finds occurrences of "iss" in the middle of  words.  (\B  matches
+       only  if  the  current position in the subject is not a word boundary.)
+       When applied to the string "Mississipi" the first call  to  pcre_exec()
+       finds  the  first  occurrence. If pcre_exec() is called again with just
+       the remainder of the subject,  namely  "issipi",  it  does  not  match,
+       because \B is always false at the start of the subject, which is deemed
+       to be a word boundary. However, if pcre_exec()  is  passed  the  entire
+       string again, but with startoffset set to 4, it finds the second occur-
+       rence of "iss" because it is able to look behind the starting point  to
+       discover that it is preceded by a letter.
+
+       If  a  non-zero starting offset is passed when the pattern is anchored,
+       one attempt to match at the given offset is made. This can only succeed
+       if  the  pattern  does  not require the match to be at the start of the
+       subject.
+
+   How pcre_exec() returns captured substrings
+
+       In general, a pattern matches a certain portion of the subject, and  in
+       addition,  further  substrings  from  the  subject may be picked out by
+       parts of the pattern. Following the usage  in  Jeffrey  Friedl's  book,
+       this  is  called "capturing" in what follows, and the phrase "capturing
+       subpattern" is used for a fragment of a pattern that picks out  a  sub-
+       string.  PCRE  supports several other kinds of parenthesized subpattern
+       that do not cause substrings to be captured.
+
+       Captured substrings are returned to the caller via a vector of integers
+       whose  address is passed in ovector. The number of elements in the vec-
+       tor is passed in ovecsize, which must be a non-negative  number.  Note:
+       this argument is NOT the size of ovector in bytes.
+
+       The  first  two-thirds of the vector is used to pass back captured sub-
+       strings, each substring using a pair of integers. The  remaining  third
+       of  the  vector is used as workspace by pcre_exec() while matching cap-
+       turing subpatterns, and is not available for passing back  information.
+       The  number passed in ovecsize should always be a multiple of three. If
+       it is not, it is rounded down.
+
+       When a match is successful, information about  captured  substrings  is
+       returned  in  pairs  of integers, starting at the beginning of ovector,
+       and continuing up to two-thirds of its length at the  most.  The  first
+       element  of  each pair is set to the byte offset of the first character
+       in a substring, and the second is set to the byte offset of  the  first
+       character  after  the end of a substring. Note: these values are always
+       byte offsets, even in UTF-8 mode. They are not character counts.
+
+       The first pair of integers, ovector[0]  and  ovector[1],  identify  the
+       portion  of  the subject string matched by the entire pattern. The next
+       pair is used for the first capturing subpattern, and so on.  The  value
+       returned by pcre_exec() is one more than the highest numbered pair that
+       has been set.  For example, if two substrings have been  captured,  the
+       returned  value is 3. If there are no capturing subpatterns, the return
+       value from a successful match is 1, indicating that just the first pair
+       of offsets has been set.
+
+       If a capturing subpattern is matched repeatedly, it is the last portion
+       of the string that it matched that is returned.
+
+       If the vector is too small to hold all the captured substring  offsets,
+       it is used as far as possible (up to two-thirds of its length), and the
+       function returns a value of zero. If the substring offsets are  not  of
+       interest,  pcre_exec()  may  be  called with ovector passed as NULL and
+       ovecsize as zero. However, if the pattern contains back references  and
+       the  ovector is not big enough to remember the related substrings, PCRE
+       has to get additional memory for use during matching. Thus it  is  usu-
+       ally advisable to supply an ovector.
+
+       The pcre_fullinfo() function can be used to find out how many capturing
+       subpatterns there are in a compiled  pattern.  The  smallest  size  for
+       ovector  that  will allow for n captured substrings, in addition to the
+       offsets of the substring matched by the whole pattern, is (n+1)*3.
+
+       It is possible for capturing subpattern number n+1 to match  some  part
+       of the subject when subpattern n has not been used at all. For example,
+       if the string "abc" is matched  against  the  pattern  (a|(z))(bc)  the
+       return from the function is 4, and subpatterns 1 and 3 are matched, but
+       2 is not. When this happens, both values in  the  offset  pairs  corre-
+       sponding to unused subpatterns are set to -1.
+
+       Offset  values  that correspond to unused subpatterns at the end of the
+       expression are also set to -1. For example,  if  the  string  "abc"  is
+       matched  against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not
+       matched. The return from the function is 2, because  the  highest  used
+       capturing subpattern number is 1. However, you can refer to the offsets
+       for the second and third capturing subpatterns if  you  wish  (assuming
+       the vector is large enough, of course).
+
+       Some  convenience  functions  are  provided for extracting the captured
+       substrings as separate strings. These are described below.
+
+   Error return values from pcre_exec()
+
+       If pcre_exec() fails, it returns a negative number. The  following  are
+       defined in the header file:
+
+         PCRE_ERROR_NOMATCH        (-1)
+
+       The subject string did not match the pattern.
+
+         PCRE_ERROR_NULL           (-2)
+
+       Either  code  or  subject  was  passed as NULL, or ovector was NULL and
+       ovecsize was not zero.
+
+         PCRE_ERROR_BADOPTION      (-3)
+
+       An unrecognized bit was set in the options argument.
+
+         PCRE_ERROR_BADMAGIC       (-4)
+
+       PCRE stores a 4-byte "magic number" at the start of the compiled  code,
+       to catch the case when it is passed a junk pointer and to detect when a
+       pattern that was compiled in an environment of one endianness is run in
+       an  environment  with the other endianness. This is the error that PCRE
+       gives when the magic number is not present.
+
+         PCRE_ERROR_UNKNOWN_OPCODE (-5)
+
+       While running the pattern match, an unknown item was encountered in the
+       compiled  pattern.  This  error  could be caused by a bug in PCRE or by
+       overwriting of the compiled pattern.
+
+         PCRE_ERROR_NOMEMORY       (-6)
+
+       If a pattern contains back references, but the ovector that  is  passed
+       to pcre_exec() is not big enough to remember the referenced substrings,
+       PCRE gets a block of memory at the start of matching to  use  for  this
+       purpose.  If the call via pcre_malloc() fails, this error is given. The
+       memory is automatically freed at the end of matching.
+
+         PCRE_ERROR_NOSUBSTRING    (-7)
+
+       This error is used by the pcre_copy_substring(),  pcre_get_substring(),
+       and  pcre_get_substring_list()  functions  (see  below).  It  is  never
+       returned by pcre_exec().
+
+         PCRE_ERROR_MATCHLIMIT     (-8)
+
+       The backtracking limit, as specified by  the  match_limit  field  in  a
+       pcre_extra  structure  (or  defaulted) was reached. See the description
+       above.
+
+         PCRE_ERROR_CALLOUT        (-9)
+
+       This error is never generated by pcre_exec() itself. It is provided for
+       use  by  callout functions that want to yield a distinctive error code.
+       See the pcrecallout documentation for details.
+
+         PCRE_ERROR_BADUTF8        (-10)
+
+       A string that contains an invalid UTF-8 byte sequence was passed  as  a
+       subject.
+
+         PCRE_ERROR_BADUTF8_OFFSET (-11)
+
+       The UTF-8 byte sequence that was passed as a subject was valid, but the
+       value of startoffset did not point to the beginning of a UTF-8  charac-
+       ter.
+
+         PCRE_ERROR_PARTIAL        (-12)
+
+       The  subject  string did not match, but it did match partially. See the
+       pcrepartial documentation for details of partial matching.
+
+         PCRE_ERROR_BADPARTIAL     (-13)
+
+       This code is no longer in  use.  It  was  formerly  returned  when  the
+       PCRE_PARTIAL  option  was used with a compiled pattern containing items
+       that were  not  supported  for  partial  matching.  From  release  8.00
+       onwards, there are no restrictions on partial matching.
+
+         PCRE_ERROR_INTERNAL       (-14)
+
+       An  unexpected  internal error has occurred. This error could be caused
+       by a bug in PCRE or by overwriting of the compiled pattern.
+
+         PCRE_ERROR_BADCOUNT       (-15)
+
+       This error is given if the value of the ovecsize argument is negative.
+
+         PCRE_ERROR_RECURSIONLIMIT (-21)
+
+       The internal recursion limit, as specified by the match_limit_recursion
+       field  in  a  pcre_extra  structure (or defaulted) was reached. See the
+       description above.
+
+         PCRE_ERROR_BADNEWLINE     (-23)
+
+       An invalid combination of PCRE_NEWLINE_xxx options was given.
+
+       Error numbers -16 to -20 and -22 are not used by pcre_exec().
+
+
+EXTRACTING CAPTURED SUBSTRINGS BY NUMBER
+
+       int pcre_copy_substring(const char *subject, int *ovector,
+            int stringcount, int stringnumber, char *buffer,
+            int buffersize);
+
+       int pcre_get_substring(const char *subject, int *ovector,
+            int stringcount, int stringnumber,
+            const char **stringptr);
+
+       int pcre_get_substring_list(const char *subject,
+            int *ovector, int stringcount, const char ***listptr);
+
+       Captured substrings can be  accessed  directly  by  using  the  offsets
+       returned  by  pcre_exec()  in  ovector.  For convenience, the functions
+       pcre_copy_substring(),    pcre_get_substring(),    and    pcre_get_sub-
+       string_list()  are  provided for extracting captured substrings as new,
+       separate, zero-terminated strings. These functions identify  substrings
+       by  number.  The  next section describes functions for extracting named
+       substrings.
+
+       A substring that contains a binary zero is correctly extracted and  has
+       a  further zero added on the end, but the result is not, of course, a C
+       string.  However, you can process such a string  by  referring  to  the
+       length  that  is  returned  by  pcre_copy_substring() and pcre_get_sub-
+       string().  Unfortunately, the interface to pcre_get_substring_list() is
+       not  adequate for handling strings containing binary zeros, because the
+       end of the final string is not independently indicated.
+
+       The first three arguments are the same for all  three  of  these  func-
+       tions:  subject  is  the subject string that has just been successfully
+       matched, ovector is a pointer to the vector of integer offsets that was
+       passed to pcre_exec(), and stringcount is the number of substrings that
+       were captured by the match, including the substring  that  matched  the
+       entire regular expression. This is the value returned by pcre_exec() if
+       it is greater than zero. If pcre_exec() returned zero, indicating  that
+       it  ran out of space in ovector, the value passed as stringcount should
+       be the number of elements in the vector divided by three.
+
+       The functions pcre_copy_substring() and pcre_get_substring() extract  a
+       single  substring,  whose  number  is given as stringnumber. A value of
+       zero extracts the substring that matched the  entire  pattern,  whereas
+       higher  values  extract  the  captured  substrings.  For pcre_copy_sub-
+       string(), the string is placed in buffer,  whose  length  is  given  by
+       buffersize,  while  for  pcre_get_substring()  a new block of memory is
+       obtained via pcre_malloc, and its address is  returned  via  stringptr.
+       The  yield  of  the function is the length of the string, not including
+       the terminating zero, or one of these error codes:
+
+         PCRE_ERROR_NOMEMORY       (-6)
+
+       The buffer was too small for pcre_copy_substring(), or the  attempt  to
+       get memory failed for pcre_get_substring().
+
+         PCRE_ERROR_NOSUBSTRING    (-7)
+
+       There is no substring whose number is stringnumber.
+
+       The  pcre_get_substring_list()  function  extracts  all  available sub-
+       strings and builds a list of pointers to them. All this is  done  in  a
+       single block of memory that is obtained via pcre_malloc. The address of
+       the memory block is returned via listptr, which is also  the  start  of
+       the  list  of  string pointers. The end of the list is marked by a NULL
+       pointer. The yield of the function is zero if all  went  well,  or  the
+       error code
+
+         PCRE_ERROR_NOMEMORY       (-6)
+
+       if the attempt to get the memory block failed.
+
+       When  any of these functions encounter a substring that is unset, which
+       can happen when capturing subpattern number n+1 matches  some  part  of
+       the  subject, but subpattern n has not been used at all, they return an
+       empty string. This can be distinguished from a genuine zero-length sub-
+       string  by inspecting the appropriate offset in ovector, which is nega-
+       tive for unset substrings.
+
+       The two convenience functions pcre_free_substring() and  pcre_free_sub-
+       string_list()  can  be  used  to free the memory returned by a previous
+       call  of  pcre_get_substring()  or  pcre_get_substring_list(),  respec-
+       tively.  They  do  nothing  more  than  call the function pointed to by
+       pcre_free, which of course could be called directly from a  C  program.
+       However,  PCRE is used in some situations where it is linked via a spe-
+       cial  interface  to  another  programming  language  that  cannot   use
+       pcre_free  directly;  it is for these cases that the functions are pro-
+       vided.
+
+
+EXTRACTING CAPTURED SUBSTRINGS BY NAME
+
+       int pcre_get_stringnumber(const pcre *code,
+            const char *name);
+
+       int pcre_copy_named_substring(const pcre *code,
+            const char *subject, int *ovector,
+            int stringcount, const char *stringname,
+            char *buffer, int buffersize);
+
+       int pcre_get_named_substring(const pcre *code,
+            const char *subject, int *ovector,
+            int stringcount, const char *stringname,
+            const char **stringptr);
+
+       To extract a substring by name, you first have to find associated  num-
+       ber.  For example, for this pattern
+
+         (a+)b(?\d+)...
+
+       the number of the subpattern called "xxx" is 2. If the name is known to
+       be unique (PCRE_DUPNAMES was not set), you can find the number from the
+       name by calling pcre_get_stringnumber(). The first argument is the com-
+       piled pattern, and the second is the name. The yield of the function is
+       the  subpattern  number,  or PCRE_ERROR_NOSUBSTRING (-7) if there is no
+       subpattern of that name.
+
+       Given the number, you can extract the substring directly, or use one of
+       the functions described in the previous section. For convenience, there
+       are also two functions that do the whole job.
+
+       Most   of   the   arguments    of    pcre_copy_named_substring()    and
+       pcre_get_named_substring()  are  the  same  as  those for the similarly
+       named functions that extract by number. As these are described  in  the
+       previous  section,  they  are not re-described here. There are just two
+       differences:
+
+       First, instead of a substring number, a substring name is  given.  Sec-
+       ond, there is an extra argument, given at the start, which is a pointer
+       to the compiled pattern. This is needed in order to gain access to  the
+       name-to-number translation table.
+
+       These  functions call pcre_get_stringnumber(), and if it succeeds, they
+       then call pcre_copy_substring() or pcre_get_substring(),  as  appropri-
+       ate.  NOTE:  If PCRE_DUPNAMES is set and there are duplicate names, the
+       behaviour may not be what you want (see the next section).
+
+       Warning: If the pattern uses the (?| feature to set up multiple subpat-
+       terns  with  the  same number, as described in the section on duplicate
+       subpattern numbers in the pcrepattern page, you  cannot  use  names  to
+       distinguish  the  different subpatterns, because names are not included
+       in the compiled code. The matching process uses only numbers. For  this
+       reason,  the  use of different names for subpatterns of the same number
+       causes an error at compile time.
+
+
+DUPLICATE SUBPATTERN NAMES
+
+       int pcre_get_stringtable_entries(const pcre *code,
+            const char *name, char **first, char **last);
+
+       When a pattern is compiled with the  PCRE_DUPNAMES  option,  names  for
+       subpatterns  are not required to be unique. (Duplicate names are always
+       allowed for subpatterns with the same number, created by using the  (?|
+       feature.  Indeed,  if  such subpatterns are named, they are required to
+       use the same names.)
+
+       Normally, patterns with duplicate names are such that in any one match,
+       only  one of the named subpatterns participates. An example is shown in
+       the pcrepattern documentation.
+
+       When   duplicates   are   present,   pcre_copy_named_substring()    and
+       pcre_get_named_substring()  return the first substring corresponding to
+       the given name that is set. If  none  are  set,  PCRE_ERROR_NOSUBSTRING
+       (-7)  is  returned;  no  data  is returned. The pcre_get_stringnumber()
+       function returns one of the numbers that are associated with the  name,
+       but it is not defined which it is.
+
+       If  you want to get full details of all captured substrings for a given
+       name, you must use  the  pcre_get_stringtable_entries()  function.  The
+       first argument is the compiled pattern, and the second is the name. The
+       third and fourth are pointers to variables which  are  updated  by  the
+       function. After it has run, they point to the first and last entries in
+       the name-to-number table  for  the  given  name.  The  function  itself
+       returns  the  length  of  each entry, or PCRE_ERROR_NOSUBSTRING (-7) if
+       there are none. The format of the table is described above in the  sec-
+       tion  entitled  Information  about  a  pattern.  Given all the relevant
+       entries for the name, you can extract each of their numbers, and  hence
+       the captured data, if any.
+
+
+FINDING ALL POSSIBLE MATCHES
+
+       The  traditional  matching  function  uses a similar algorithm to Perl,
+       which stops when it finds the first match, starting at a given point in
+       the  subject.  If you want to find all possible matches, or the longest
+       possible match, consider using the alternative matching  function  (see
+       below)  instead.  If you cannot use the alternative function, but still
+       need to find all possible matches, you can kludge it up by  making  use
+       of the callout facility, which is described in the pcrecallout documen-
+       tation.
+
+       What you have to do is to insert a callout right at the end of the pat-
+       tern.   When your callout function is called, extract and save the cur-
+       rent matched substring. Then return  1,  which  forces  pcre_exec()  to
+       backtrack  and  try other alternatives. Ultimately, when it runs out of
+       matches, pcre_exec() will yield PCRE_ERROR_NOMATCH.
+
+
+MATCHING A PATTERN: THE ALTERNATIVE FUNCTION
+
+       int pcre_dfa_exec(const pcre *code, const pcre_extra *extra,
+            const char *subject, int length, int startoffset,
+            int options, int *ovector, int ovecsize,
+            int *workspace, int wscount);
+
+       The function pcre_dfa_exec()  is  called  to  match  a  subject  string
+       against  a  compiled pattern, using a matching algorithm that scans the
+       subject string just once, and does not backtrack.  This  has  different
+       characteristics  to  the  normal  algorithm, and is not compatible with
+       Perl. Some of the features of PCRE patterns are not  supported.  Never-
+       theless,  there are times when this kind of matching can be useful. For
+       a discussion of the two matching algorithms, and  a  list  of  features
+       that  pcre_dfa_exec() does not support, see the pcrematching documenta-
+       tion.
+
+       The arguments for the pcre_dfa_exec() function  are  the  same  as  for
+       pcre_exec(), plus two extras. The ovector argument is used in a differ-
+       ent way, and this is described below. The other  common  arguments  are
+       used  in  the  same way as for pcre_exec(), so their description is not
+       repeated here.
+
+       The two additional arguments provide workspace for  the  function.  The
+       workspace  vector  should  contain at least 20 elements. It is used for
+       keeping  track  of  multiple  paths  through  the  pattern  tree.  More
+       workspace  will  be  needed for patterns and subjects where there are a
+       lot of potential matches.
+
+       Here is an example of a simple call to pcre_dfa_exec():
+
+         int rc;
+         int ovector[10];
+         int wspace[20];
+         rc = pcre_dfa_exec(
+           re,             /* result of pcre_compile() */
+           NULL,           /* we didn't study the pattern */
+           "some string",  /* the subject string */
+           11,             /* the length of the subject string */
+           0,              /* start at offset 0 in the subject */
+           0,              /* default options */
+           ovector,        /* vector of integers for substring information */
+           10,             /* number of elements (NOT size in bytes) */
+           wspace,         /* working space vector */
+           20);            /* number of elements (NOT size in bytes) */
+
+   Option bits for pcre_dfa_exec()
+
+       The unused bits of the options argument  for  pcre_dfa_exec()  must  be
+       zero.  The  only  bits  that  may  be  set are PCRE_ANCHORED, PCRE_NEW-
+       LINE_xxx,        PCRE_NOTBOL,        PCRE_NOTEOL,        PCRE_NOTEMPTY,
+       PCRE_NOTEMPTY_ATSTART, PCRE_NO_UTF8_CHECK, PCRE_PARTIAL_HARD, PCRE_PAR-
+       TIAL_SOFT, PCRE_DFA_SHORTEST, and PCRE_DFA_RESTART. All  but  the  last
+       four  of  these  are  exactly  the  same  as  for pcre_exec(), so their
+       description is not repeated here.
+
+         PCRE_PARTIAL_HARD
+         PCRE_PARTIAL_SOFT
+
+       These have the same general effect as they do for pcre_exec(), but  the
+       details  are  slightly  different.  When  PCRE_PARTIAL_HARD  is set for
+       pcre_dfa_exec(), it returns PCRE_ERROR_PARTIAL if the end of  the  sub-
+       ject  is  reached  and there is still at least one matching possibility
+       that requires additional characters. This happens even if some complete
+       matches have also been found. When PCRE_PARTIAL_SOFT is set, the return
+       code PCRE_ERROR_NOMATCH is converted into PCRE_ERROR_PARTIAL if the end
+       of  the  subject  is  reached, there have been no complete matches, but
+       there is still at least one matching possibility. The  portion  of  the
+       string  that  was inspected when the longest partial match was found is
+       set as the first matching string in both cases.
+
+         PCRE_DFA_SHORTEST
+
+       Setting the PCRE_DFA_SHORTEST option causes the matching  algorithm  to
+       stop as soon as it has found one match. Because of the way the alterna-
+       tive algorithm works, this is necessarily the shortest  possible  match
+       at the first possible matching point in the subject string.
+
+         PCRE_DFA_RESTART
+
+       When pcre_dfa_exec() returns a partial match, it is possible to call it
+       again, with additional subject characters, and have  it  continue  with
+       the  same match. The PCRE_DFA_RESTART option requests this action; when
+       it is set, the workspace and wscount options must  reference  the  same
+       vector  as  before  because data about the match so far is left in them
+       after a partial match. There is more discussion of this facility in the
+       pcrepartial documentation.
+
+   Successful returns from pcre_dfa_exec()
+
+       When  pcre_dfa_exec()  succeeds, it may have matched more than one sub-
+       string in the subject. Note, however, that all the matches from one run
+       of  the  function  start  at the same point in the subject. The shorter
+       matches are all initial substrings of the longer matches. For  example,
+       if the pattern
+
+         <.*>
+
+       is matched against the string
+
+         This is    no more
+
+       the three matched strings are
+
+         
+          
+           
+
+       On  success,  the  yield of the function is a number greater than zero,
+       which is the number of matched substrings.  The  substrings  themselves
+       are  returned  in  ovector. Each string uses two elements; the first is
+       the offset to the start, and the second is the offset to  the  end.  In
+       fact,  all  the  strings  have the same start offset. (Space could have
+       been saved by giving this only once, but it was decided to retain  some
+       compatibility  with  the  way pcre_exec() returns data, even though the
+       meaning of the strings is different.)
+
+       The strings are returned in reverse order of length; that is, the long-
+       est  matching  string is given first. If there were too many matches to
+       fit into ovector, the yield of the function is zero, and the vector  is
+       filled with the longest matches.
+
+   Error returns from pcre_dfa_exec()
+
+       The  pcre_dfa_exec()  function returns a negative number when it fails.
+       Many of the errors are the same  as  for  pcre_exec(),  and  these  are
+       described  above.   There are in addition the following errors that are
+       specific to pcre_dfa_exec():
+
+         PCRE_ERROR_DFA_UITEM      (-16)
+
+       This return is given if pcre_dfa_exec() encounters an item in the  pat-
+       tern  that  it  does not support, for instance, the use of \C or a back
+       reference.
+
+         PCRE_ERROR_DFA_UCOND      (-17)
+
+       This return is given if pcre_dfa_exec()  encounters  a  condition  item
+       that  uses  a back reference for the condition, or a test for recursion
+       in a specific group. These are not supported.
+
+         PCRE_ERROR_DFA_UMLIMIT    (-18)
+
+       This return is given if pcre_dfa_exec() is called with an  extra  block
+       that contains a setting of the match_limit field. This is not supported
+       (it is meaningless).
+
+         PCRE_ERROR_DFA_WSSIZE     (-19)
+
+       This return is given if  pcre_dfa_exec()  runs  out  of  space  in  the
+       workspace vector.
+
+         PCRE_ERROR_DFA_RECURSE    (-20)
+
+       When  a  recursive subpattern is processed, the matching function calls
+       itself recursively, using private vectors for  ovector  and  workspace.
+       This  error  is  given  if  the output vector is not large enough. This
+       should be extremely rare, as a vector of size 1000 is used.

+
+
+PCRE CALLOUTS
+
+       int (*pcre_callout)(pcre_callout_block *);
+
+       PCRE provides a feature called "callout", which is a means of temporar-
+       ily passing control to the caller of PCRE  in  the  middle  of  pattern
+       matching.  The  caller of PCRE provides an external function by putting
+       its entry point in the global variable pcre_callout. By  default,  this
+       variable contains NULL, which disables all calling out.
+
+       Within  a  regular  expression,  (?C) indicates the points at which the
+       external function is to be called.  Different  callout  points  can  be
+       identified  by  putting  a number less than 256 after the letter C. The
+       default value is zero.  For  example,  this  pattern  has  two  callout
+       points:
+
+         (?C1)abc(?C2)def
+
+       If  the  PCRE_AUTO_CALLOUT  option  bit  is  set when pcre_compile() or
+       pcre_compile2() is called, PCRE  automatically  inserts  callouts,  all
+       with  number  255,  before  each  item  in the pattern. For example, if
+       PCRE_AUTO_CALLOUT is used with the pattern
+
+         A(\d{2}|--)
+
+       it is processed as if it were
+
+       (?C255)A(?C255)((?C255)\d{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+
+       Notice that there is a callout before and after  each  parenthesis  and
+       alternation  bar.  Automatic  callouts  can  be  used  for tracking the
+       progress of pattern matching. The pcretest command has an  option  that
+       sets  automatic callouts; when it is used, the output indicates how the
+       pattern is matched. This is useful information when you are  trying  to
+       optimize the performance of a particular pattern.
+
+
+MISSING CALLOUTS
+
+       You  should  be  aware  that,  because of optimizations in the way PCRE
+       matches patterns by default, callouts  sometimes  do  not  happen.  For
+       example, if the pattern is
+
+         ab(?C4)cd
+
+       PCRE knows that any matching string must contain the letter "d". If the
+       subject string is "abyz", the lack of "d" means that  matching  doesn't
+       ever  start,  and  the  callout is never reached. However, with "abyd",
+       though the result is still no match, the callout is obeyed.
+
+       If the pattern is studied, PCRE knows the minimum length of a  matching
+       string,  and will immediately give a "no match" return without actually
+       running a match if the subject is not long enough, or,  for  unanchored
+       patterns, if it has been scanned far enough.
+
+       You  can disable these optimizations by passing the PCRE_NO_START_OPTI-
+       MIZE option to pcre_exec() or  pcre_dfa_exec().  This  slows  down  the
+       matching  process,  but  does  ensure that callouts such as the example
+       above are obeyed.
+
+
+THE CALLOUT INTERFACE
+
+       During matching, when PCRE reaches a callout point, the external  func-
+       tion  defined by pcre_callout is called (if it is set). This applies to
+       both the pcre_exec() and the pcre_dfa_exec()  matching  functions.  The
+       only  argument  to  the callout function is a pointer to a pcre_callout
+       block. This structure contains the following fields:
+
+         int          version;
+         int          callout_number;
+         int         *offset_vector;
+         const char  *subject;
+         int          subject_length;
+         int          start_match;
+         int          current_position;
+         int          capture_top;
+         int          capture_last;
+         void        *callout_data;
+         int          pattern_position;
+         int          next_item_length;
+
+       The version field is an integer containing the version  number  of  the
+       block  format. The initial version was 0; the current version is 1. The
+       version number will change again in future  if  additional  fields  are
+       added, but the intention is never to remove any of the existing fields.
+
+       The  callout_number  field  contains the number of the callout, as com-
+       piled into the pattern (that is, the number after ?C for  manual  call-
+       outs, and 255 for automatically generated callouts).
+
+       The  offset_vector field is a pointer to the vector of offsets that was
+       passed  by  the  caller  to  pcre_exec()   or   pcre_dfa_exec().   When
+       pcre_exec()  is used, the contents can be inspected in order to extract
+       substrings that have been matched so  far,  in  the  same  way  as  for
+       extracting  substrings after a match has completed. For pcre_dfa_exec()
+       this field is not useful.
+
+       The subject and subject_length fields contain copies of the values that
+       were passed to pcre_exec().
+
+       The  start_match  field normally contains the offset within the subject
+       at which the current match attempt  started.  However,  if  the  escape
+       sequence  \K has been encountered, this value is changed to reflect the
+       modified starting point. If the pattern is not  anchored,  the  callout
+       function may be called several times from the same point in the pattern
+       for different starting points in the subject.
+
+       The current_position field contains the offset within  the  subject  of
+       the current match pointer.
+
+       When  the  pcre_exec() function is used, the capture_top field contains
+       one more than the number of the highest numbered captured substring  so
+       far.  If  no substrings have been captured, the value of capture_top is
+       one. This is always the case when pcre_dfa_exec() is used,  because  it
+       does not support captured substrings.
+
+       The  capture_last  field  contains the number of the most recently cap-
+       tured substring. If no substrings have been captured, its value is  -1.
+       This is always the case when pcre_dfa_exec() is used.
+
+       The  callout_data  field contains a value that is passed to pcre_exec()
+       or pcre_dfa_exec() specifically so that it can be passed back in  call-
+       outs.  It  is  passed  in the pcre_callout field of the pcre_extra data
+       structure. If no such data was passed, the value of callout_data  in  a
+       pcre_callout  block  is  NULL. There is a description of the pcre_extra
+       structure in the pcreapi documentation.
+
+       The pattern_position field is present from version 1 of the  pcre_call-
+       out structure. It contains the offset to the next item to be matched in
+       the pattern string.
+
+       The next_item_length field is present from version 1 of the  pcre_call-
+       out structure. It contains the length of the next item to be matched in
+       the pattern string. When the callout immediately precedes  an  alterna-
+       tion  bar, a closing parenthesis, or the end of the pattern, the length
+       is zero. When the callout precedes an opening parenthesis,  the  length
+       is that of the entire subpattern.
+
+       The  pattern_position  and next_item_length fields are intended to help
+       in distinguishing between different automatic callouts, which all  have
+       the same callout number. However, they are set for all callouts.
+
+
+RETURN VALUES
+
+       The  external callout function returns an integer to PCRE. If the value
+       is zero, matching proceeds as normal. If  the  value  is  greater  than
+       zero,  matching  fails  at  the current point, but the testing of other
+       matching possibilities goes ahead, just as if a lookahead assertion had
+       failed.  If  the  value  is less than zero, the match is abandoned, and
+       pcre_exec() or pcre_dfa_exec() returns the negative value.
+
+       Negative  values  should  normally  be   chosen   from   the   set   of
+       PCRE_ERROR_xxx values. In particular, PCRE_ERROR_NOMATCH forces a stan-
+       dard "no  match"  failure.   The  error  number  PCRE_ERROR_CALLOUT  is
+       reserved  for  use  by callout functions; it will never be used by PCRE
+       itself.

+PCRECOMPAT(3)                                                    PCRECOMPAT(3)

+
+
+DIFFERENCES BETWEEN PCRE AND PERL
+
+       This  document describes the differences in the ways that PCRE and Perl
+       handle regular expressions. The differences  described  here  are  with
+       respect to Perl 5.10.
+
+       1.  PCRE has only a subset of Perl's UTF-8 and Unicode support. Details
+       of what it does have are given in the section on UTF-8 support  in  the
+       main pcre page.
+
+       2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl
+       permits them, but they do not mean what you might think.  For  example,
+       (?!a){3} does not assert that the next three characters are not "a". It
+       just asserts that the next character is not "a" three times.
+
+       3. Capturing subpatterns that occur inside  negative  lookahead  asser-
+       tions  are  counted,  but their entries in the offsets vector are never
+       set. Perl sets its numerical variables from any such patterns that  are
+       matched before the assertion fails to match something (thereby succeed-
+       ing), but only if the negative lookahead assertion  contains  just  one
+       branch.
+
+       4.  Though  binary zero characters are supported in the subject string,
+       they are not allowed in a pattern string because it is passed as a nor-
+       mal C string, terminated by zero. The escape sequence \0 can be used in
+       the pattern to represent a binary zero.
+
+       5. The following Perl escape sequences are not supported: \l,  \u,  \L,
+       \U, and \N. In fact these are implemented by Perl's general string-han-
+       dling and are not part of its pattern matching engine. If any of  these
+       are encountered by PCRE, an error is generated.
+
+       6.  The Perl escape sequences \p, \P, and \X are supported only if PCRE
+       is built with Unicode character property support. The  properties  that
+       can  be tested with \p and \P are limited to the general category prop-
+       erties such as Lu and Nd, script names such as Greek or  Han,  and  the
+       derived  properties  Any  and  L&. PCRE does support the Cs (surrogate)
+       property, which Perl does not; the  Perl  documentation  says  "Because
+       Perl hides the need for the user to understand the internal representa-
+       tion of Unicode characters, there is no need to implement the  somewhat
+       messy concept of surrogates."
+
+       7. PCRE does support the \Q...\E escape for quoting substrings. Charac-
+       ters in between are treated as literals.  This  is  slightly  different
+       from  Perl  in  that  $  and  @ are also handled as literals inside the
+       quotes. In Perl, they cause variable interpolation (but of course  PCRE
+       does not have variables). Note the following examples:
+
+           Pattern            PCRE matches      Perl matches
+
+           \Qabc$xyz\E        abc$xyz           abc followed by the
+                                                  contents of $xyz
+           \Qabc\$xyz\E       abc\$xyz          abc\$xyz
+           \Qabc\E\$\Qxyz\E   abc$xyz           abc$xyz
+
+       The  \Q...\E  sequence  is recognized both inside and outside character
+       classes.
+
+       8. Fairly obviously, PCRE does not support the (?{code}) and (??{code})
+       constructions.  However,  there is support for recursive patterns. This
+       is not available in Perl 5.8, but it is in Perl 5.10.  Also,  the  PCRE
+       "callout"  feature allows an external function to be called during pat-
+       tern matching. See the pcrecallout documentation for details.
+
+       9. Subpatterns that are called  recursively  or  as  "subroutines"  are
+       always  treated  as  atomic  groups  in  PCRE. This is like Python, but
+       unlike Perl. There is a discussion of an example that explains this  in
+       more  detail  in  the section on recursion differences from Perl in the
+       pcrepattern page.
+
+       10. There are some differences that are concerned with the settings  of
+       captured  strings  when  part  of  a  pattern is repeated. For example,
+       matching "aba" against the  pattern  /^(a(b)?)+$/  in  Perl  leaves  $2
+       unset, but in PCRE it is set to "b".
+
+       11.  PCRE  does  support  Perl  5.10's  backtracking  verbs  (*ACCEPT),
+       (*FAIL), (*F), (*COMMIT), (*PRUNE), (*SKIP), and (*THEN), but  only  in
+       the forms without an argument. PCRE does not support (*MARK).
+
+       12.  PCRE's handling of duplicate subpattern numbers and duplicate sub-
+       pattern names is not as general as Perl's. This is a consequence of the
+       fact the PCRE works internally just with numbers, using an external ta-
+       ble to translate between numbers and names. In  particular,  a  pattern
+       such  as  (?|(?A)|(? (Oniguruma syntax) are not synonymous. The  former  is  a  back
+       reference; the latter is a subroutine call.
+
+   Generic character types
+
+       Another use of backslash is for specifying generic character types. The
+       following are always recognized:
+
+         \d     any decimal digit
+         \D     any character that is not a decimal digit
+         \h     any horizontal whitespace character
+         \H     any character that is not a horizontal whitespace character
+         \s     any whitespace character
+         \S     any character that is not a whitespace character
+         \v     any vertical whitespace character
+         \V     any character that is not a vertical whitespace character
+         \w     any "word" character
+         \W     any "non-word" character
+
+       Each pair of escape sequences partitions the complete set of characters
+       into  two disjoint sets. Any given character matches one, and only one,
+       of each pair.
+
+       These character type sequences can appear both inside and outside char-
+       acter  classes.  They each match one character of the appropriate type.
+       If the current matching point is at the end of the subject string,  all
+       of them fail, since there is no character to match.
+
+       For  compatibility  with Perl, \s does not match the VT character (code
+       11).  This makes it different from the the POSIX "space" class. The  \s
+       characters  are  HT  (9), LF (10), FF (12), CR (13), and space (32). If
+       "use locale;" is included in a Perl script, \s may match the VT charac-
+       ter. In PCRE, it never does.
+
+       In  UTF-8 mode, characters with values greater than 128 never match \d,
+       \s, or \w, and always match \D, \S, and \W. This is true even when Uni-
+       code  character  property  support is available. These sequences retain
+       their original meanings from before UTF-8 support was available, mainly
+       for  efficiency  reasons. Note that this also affects \b, because it is
+       defined in terms of \w and \W.
+
+       The sequences \h, \H, \v, and \V are Perl 5.10 features. In contrast to
+       the  other  sequences, these do match certain high-valued codepoints in
+       UTF-8 mode.  The horizontal space characters are:
+
+         U+0009     Horizontal tab
+         U+0020     Space
+         U+00A0     Non-break space
+         U+1680     Ogham space mark
+         U+180E     Mongolian vowel separator
+         U+2000     En quad
+         U+2001     Em quad
+         U+2002     En space
+         U+2003     Em space
+         U+2004     Three-per-em space
+         U+2005     Four-per-em space
+         U+2006     Six-per-em space
+         U+2007     Figure space
+         U+2008     Punctuation space
+         U+2009     Thin space
+         U+200A     Hair space
+         U+202F     Narrow no-break space
+         U+205F     Medium mathematical space
+         U+3000     Ideographic space
+
+       The vertical space characters are:
+
+         U+000A     Linefeed
+         U+000B     Vertical tab
+         U+000C     Formfeed
+         U+000D     Carriage return
+         U+0085     Next line
+         U+2028     Line separator
+         U+2029     Paragraph separator
+
+       A "word" character is an underscore or any character less than 256 that
+       is  a  letter  or  digit.  The definition of letters and digits is con-
+       trolled by PCRE's low-valued character tables, and may vary if  locale-
+       specific  matching is taking place (see "Locale support" in the pcreapi
+       page). For example, in a French locale such  as  "fr_FR"  in  Unix-like
+       systems,  or "french" in Windows, some character codes greater than 128
+       are used for accented letters, and these are matched by \w. The use  of
+       locales with Unicode is discouraged.
+
+   Newline sequences
+
+       Outside  a  character class, by default, the escape sequence \R matches
+       any Unicode newline sequence. This is a Perl 5.10 feature. In non-UTF-8
+       mode \R is equivalent to the following:
+
+         (?>\r\n|\n|\x0b|\f|\r|\x85)
+
+       This  is  an  example  of an "atomic group", details of which are given
+       below.  This particular group matches either the two-character sequence
+       CR  followed  by  LF,  or  one  of  the single characters LF (linefeed,
+       U+000A), VT (vertical tab, U+000B), FF (formfeed, U+000C), CR (carriage
+       return, U+000D), or NEL (next line, U+0085). The two-character sequence
+       is treated as a single unit that cannot be split.
+
+       In UTF-8 mode, two additional characters whose codepoints  are  greater
+       than 255 are added: LS (line separator, U+2028) and PS (paragraph sepa-
+       rator, U+2029).  Unicode character property support is not  needed  for
+       these characters to be recognized.
+
+       It is possible to restrict \R to match only CR, LF, or CRLF (instead of
+       the complete set  of  Unicode  line  endings)  by  setting  the  option
+       PCRE_BSR_ANYCRLF either at compile time or when the pattern is matched.
+       (BSR is an abbrevation for "backslash R".) This can be made the default
+       when  PCRE  is  built;  if this is the case, the other behaviour can be
+       requested via the PCRE_BSR_UNICODE option.   It  is  also  possible  to
+       specify  these  settings  by  starting a pattern string with one of the
+       following sequences:
+
+         (*BSR_ANYCRLF)   CR, LF, or CRLF only
+         (*BSR_UNICODE)   any Unicode newline sequence
+
+       These override the default and the options given to  pcre_compile()  or
+       pcre_compile2(),  but  they  can  be  overridden  by  options  given to
+       pcre_exec() or pcre_dfa_exec(). Note that these special settings, which
+       are  not  Perl-compatible,  are  recognized only at the very start of a
+       pattern, and that they must be in upper case. If more than one of  them
+       is present, the last one is used. They can be combined with a change of
+       newline convention, for example, a pattern can start with:
+
+         (*ANY)(*BSR_ANYCRLF)
+
+       Inside a character class, \R matches the letter "R".
+
+   Unicode character properties
+
+       When PCRE is built with Unicode character property support, three addi-
+       tional  escape sequences that match characters with specific properties
+       are available.  When not in UTF-8 mode, these sequences are  of  course
+       limited  to  testing characters whose codepoints are less than 256, but
+       they do work in this mode.  The extra escape sequences are:
+
+         \p{xx}   a character with the xx property
+         \P{xx}   a character without the xx property
+         \X       an extended Unicode sequence
+
+       The property names represented by xx above are limited to  the  Unicode
+       script names, the general category properties, and "Any", which matches
+       any character (including newline). Other properties such as "InMusical-
+       Symbols"  are  not  currently supported by PCRE. Note that \P{Any} does
+       not match any characters, so always causes a match failure.
+
+       Sets of Unicode characters are defined as belonging to certain scripts.
+       A  character from one of these sets can be matched using a script name.
+       For example:
+
+         \p{Greek}
+         \P{Han}
+
+       Those that are not part of an identified script are lumped together  as
+       "Common". The current list of scripts is:
+
+       Arabic,  Armenian,  Balinese,  Bengali,  Bopomofo,  Braille,  Buginese,
+       Buhid,  Canadian_Aboriginal,  Cherokee,  Common,   Coptic,   Cuneiform,
+       Cypriot, Cyrillic, Deseret, Devanagari, Ethiopic, Georgian, Glagolitic,
+       Gothic, Greek, Gujarati, Gurmukhi, Han, Hangul, Hanunoo, Hebrew,  Hira-
+       gana,  Inherited,  Kannada,  Katakana,  Kharoshthi,  Khmer, Lao, Latin,
+       Limbu,  Linear_B,  Malayalam,  Mongolian,  Myanmar,  New_Tai_Lue,  Nko,
+       Ogham,  Old_Italic,  Old_Persian, Oriya, Osmanya, Phags_Pa, Phoenician,
+       Runic,  Shavian,  Sinhala,  Syloti_Nagri,  Syriac,  Tagalog,  Tagbanwa,
+       Tai_Le, Tamil, Telugu, Thaana, Thai, Tibetan, Tifinagh, Ugaritic, Yi.
+
+       Each  character has exactly one general category property, specified by
+       a two-letter abbreviation. For compatibility with Perl, negation can be
+       specified  by  including a circumflex between the opening brace and the
+       property name. For example, \p{^Lu} is the same as \P{Lu}.
+
+       If only one letter is specified with \p or \P, it includes all the gen-
+       eral  category properties that start with that letter. In this case, in
+       the absence of negation, the curly brackets in the escape sequence  are
+       optional; these two examples have the same effect:
+
+         \p{L}
+         \pL
+
+       The following general category property codes are supported:
+
+         C     Other
+         Cc    Control
+         Cf    Format
+         Cn    Unassigned
+         Co    Private use
+         Cs    Surrogate
+
+         L     Letter
+         Ll    Lower case letter
+         Lm    Modifier letter
+         Lo    Other letter
+         Lt    Title case letter
+         Lu    Upper case letter
+
+         M     Mark
+         Mc    Spacing mark
+         Me    Enclosing mark
+         Mn    Non-spacing mark
+
+         N     Number
+         Nd    Decimal number
+         Nl    Letter number
+         No    Other number
+
+         P     Punctuation
+         Pc    Connector punctuation
+         Pd    Dash punctuation
+         Pe    Close punctuation
+         Pf    Final punctuation
+         Pi    Initial punctuation
+         Po    Other punctuation
+         Ps    Open punctuation
+
+         S     Symbol
+         Sc    Currency symbol
+         Sk    Modifier symbol
+         Sm    Mathematical symbol
+         So    Other symbol
+
+         Z     Separator
+         Zl    Line separator
+         Zp    Paragraph separator
+         Zs    Space separator
+
+       The  special property L& is also supported: it matches a character that
+       has the Lu, Ll, or Lt property, in other words, a letter  that  is  not
+       classified as a modifier or "other".
+
+       The  Cs  (Surrogate)  property  applies only to characters in the range
+       U+D800 to U+DFFF. Such characters are not valid in UTF-8  strings  (see
+       RFC 3629) and so cannot be tested by PCRE, unless UTF-8 validity check-
+       ing has been turned off (see the discussion  of  PCRE_NO_UTF8_CHECK  in
+       the pcreapi page). Perl does not support the Cs property.
+
+       The  long  synonyms  for  property  names  that  Perl supports (such as
+       \p{Letter}) are not supported by PCRE, nor is it  permitted  to  prefix
+       any of these properties with "Is".
+
+       No character that is in the Unicode table has the Cn (unassigned) prop-
+       erty.  Instead, this property is assumed for any code point that is not
+       in the Unicode table.
+
+       Specifying  caseless  matching  does not affect these escape sequences.
+       For example, \p{Lu} always matches only upper case letters.
+
+       The \X escape matches any number of Unicode  characters  that  form  an
+       extended Unicode sequence. \X is equivalent to
+
+         (?>\PM\pM*)
+
+       That  is,  it matches a character without the "mark" property, followed
+       by zero or more characters with the "mark"  property,  and  treats  the
+       sequence  as  an  atomic group (see below).  Characters with the "mark"
+       property are typically accents that  affect  the  preceding  character.
+       None  of  them  have  codepoints less than 256, so in non-UTF-8 mode \X
+       matches any one character.
+
+       Matching characters by Unicode property is not fast, because  PCRE  has
+       to  search  a  structure  that  contains data for over fifteen thousand
+       characters. That is why the traditional escape sequences such as \d and
+       \w do not use Unicode properties in PCRE.
+
+   Resetting the match start
+
+       The escape sequence \K, which is a Perl 5.10 feature, causes any previ-
+       ously matched characters not  to  be  included  in  the  final  matched
+       sequence. For example, the pattern:
+
+         foo\Kbar
+
+       matches  "foobar",  but reports that it has matched "bar". This feature
+       is similar to a lookbehind assertion (described  below).   However,  in
+       this  case, the part of the subject before the real match does not have
+       to be of fixed length, as lookbehind assertions do. The use of \K  does
+       not  interfere  with  the setting of captured substrings.  For example,
+       when the pattern
+
+         (foo)\Kbar
+
+       matches "foobar", the first substring is still set to "foo".
+
+   Simple assertions
+
+       The final use of backslash is for certain simple assertions. An  asser-
+       tion  specifies a condition that has to be met at a particular point in
+       a match, without consuming any characters from the subject string.  The
+       use  of subpatterns for more complicated assertions is described below.
+       The backslashed assertions are:
+
+         \b     matches at a word boundary
+         \B     matches when not at a word boundary
+         \A     matches at the start of the subject
+         \Z     matches at the end of the subject
+                 also matches before a newline at the end of the subject
+         \z     matches only at the end of the subject
+         \G     matches at the first matching position in the subject
+
+       These assertions may not appear in character classes (but note that  \b
+       has a different meaning, namely the backspace character, inside a char-
+       acter class).
+
+       A word boundary is a position in the subject string where  the  current
+       character  and  the previous character do not both match \w or \W (i.e.
+       one matches \w and the other matches \W), or the start or  end  of  the
+       string if the first or last character matches \w, respectively. Neither
+       PCRE nor Perl has a separte "start of word" or "end  of  word"  metase-
+       quence.  However,  whatever follows \b normally determines which it is.
+       For example, the fragment \ba matches "a" at the start of a word.
+
+       The \A, \Z, and \z assertions differ from  the  traditional  circumflex
+       and dollar (described in the next section) in that they only ever match
+       at the very start and end of the subject string, whatever  options  are
+       set.  Thus,  they are independent of multiline mode. These three asser-
+       tions are not affected by the PCRE_NOTBOL or PCRE_NOTEOL options, which
+       affect  only the behaviour of the circumflex and dollar metacharacters.
+       However, if the startoffset argument of pcre_exec() is non-zero,  indi-
+       cating that matching is to start at a point other than the beginning of
+       the subject, \A can never match. The difference between \Z  and  \z  is
+       that \Z matches before a newline at the end of the string as well as at
+       the very end, whereas \z matches only at the end.
+
+       The \G assertion is true only when the current matching position is  at
+       the  start point of the match, as specified by the startoffset argument
+       of pcre_exec(). It differs from \A when the  value  of  startoffset  is
+       non-zero.  By calling pcre_exec() multiple times with appropriate argu-
+       ments, you can mimic Perl's /g option, and it is in this kind of imple-
+       mentation where \G can be useful.
+
+       Note,  however,  that  PCRE's interpretation of \G, as the start of the
+       current match, is subtly different from Perl's, which defines it as the
+       end  of  the  previous  match. In Perl, these can be different when the
+       previously matched string was empty. Because PCRE does just  one  match
+       at a time, it cannot reproduce this behaviour.
+
+       If  all  the alternatives of a pattern begin with \G, the expression is
+       anchored to the starting match position, and the "anchored" flag is set
+       in the compiled regular expression.
+
+
+CIRCUMFLEX AND DOLLAR
+
+       Outside a character class, in the default matching mode, the circumflex
+       character is an assertion that is true only  if  the  current  matching
+       point  is  at the start of the subject string. If the startoffset argu-
+       ment of pcre_exec() is non-zero, circumflex  can  never  match  if  the
+       PCRE_MULTILINE  option  is  unset. Inside a character class, circumflex
+       has an entirely different meaning (see below).
+
+       Circumflex need not be the first character of the pattern if  a  number
+       of  alternatives are involved, but it should be the first thing in each
+       alternative in which it appears if the pattern is ever  to  match  that
+       branch.  If all possible alternatives start with a circumflex, that is,
+       if the pattern is constrained to match only at the start  of  the  sub-
+       ject,  it  is  said  to be an "anchored" pattern. (There are also other
+       constructs that can cause a pattern to be anchored.)
+
+       A dollar character is an assertion that is true  only  if  the  current
+       matching  point  is  at  the  end of the subject string, or immediately
+       before a newline at the end of the string (by default). Dollar need not
+       be  the  last  character of the pattern if a number of alternatives are
+       involved, but it should be the last item in  any  branch  in  which  it
+       appears. Dollar has no special meaning in a character class.
+
+       The  meaning  of  dollar  can be changed so that it matches only at the
+       very end of the string, by setting the  PCRE_DOLLAR_ENDONLY  option  at
+       compile time. This does not affect the \Z assertion.
+
+       The meanings of the circumflex and dollar characters are changed if the
+       PCRE_MULTILINE option is set. When  this  is  the  case,  a  circumflex
+       matches  immediately after internal newlines as well as at the start of
+       the subject string. It does not match after a  newline  that  ends  the
+       string.  A dollar matches before any newlines in the string, as well as
+       at the very end, when PCRE_MULTILINE is set. When newline is  specified
+       as  the  two-character  sequence CRLF, isolated CR and LF characters do
+       not indicate newlines.
+
+       For example, the pattern /^abc$/ matches the subject string  "def\nabc"
+       (where  \n  represents a newline) in multiline mode, but not otherwise.
+       Consequently, patterns that are anchored in single  line  mode  because
+       all  branches  start  with  ^ are not anchored in multiline mode, and a
+       match for circumflex is  possible  when  the  startoffset  argument  of
+       pcre_exec()  is  non-zero. The PCRE_DOLLAR_ENDONLY option is ignored if
+       PCRE_MULTILINE is set.
+
+       Note that the sequences \A, \Z, and \z can be used to match  the  start
+       and  end of the subject in both modes, and if all branches of a pattern
+       start with \A it is always anchored, whether or not  PCRE_MULTILINE  is
+       set.
+
+
+FULL STOP (PERIOD, DOT)
+
+       Outside a character class, a dot in the pattern matches any one charac-
+       ter in the subject string except (by default) a character  that  signi-
+       fies  the  end  of  a line. In UTF-8 mode, the matched character may be
+       more than one byte long.
+
+       When a line ending is defined as a single character, dot never  matches
+       that  character; when the two-character sequence CRLF is used, dot does
+       not match CR if it is immediately followed  by  LF,  but  otherwise  it
+       matches  all characters (including isolated CRs and LFs). When any Uni-
+       code line endings are being recognized, dot does not match CR or LF  or
+       any of the other line ending characters.
+
+       The  behaviour  of  dot  with regard to newlines can be changed. If the
+       PCRE_DOTALL option is set, a dot matches  any  one  character,  without
+       exception. If the two-character sequence CRLF is present in the subject
+       string, it takes two dots to match it.
+
+       The handling of dot is entirely independent of the handling of  circum-
+       flex  and  dollar,  the  only relationship being that they both involve
+       newlines. Dot has no special meaning in a character class.
+
+
+MATCHING A SINGLE BYTE
+
+       Outside a character class, the escape sequence \C matches any one byte,
+       both  in  and  out  of  UTF-8 mode. Unlike a dot, it always matches any
+       line-ending characters. The feature is provided in  Perl  in  order  to
+       match  individual bytes in UTF-8 mode. Because it breaks up UTF-8 char-
+       acters into individual bytes, what remains in the string may be a  mal-
+       formed  UTF-8  string.  For this reason, the \C escape sequence is best
+       avoided.
+
+       PCRE does not allow \C to appear in  lookbehind  assertions  (described
+       below),  because  in UTF-8 mode this would make it impossible to calcu-
+       late the length of the lookbehind.
+
+
+SQUARE BRACKETS AND CHARACTER CLASSES
+
+       An opening square bracket introduces a character class, terminated by a
+       closing square bracket. A closing square bracket on its own is not spe-
+       cial by default.  However, if the PCRE_JAVASCRIPT_COMPAT option is set,
+       a lone closing square bracket causes a compile-time error. If a closing
+       square bracket is required as a member of the class, it should  be  the
+       first  data  character  in  the  class (after an initial circumflex, if
+       present) or escaped with a backslash.
+
+       A character class matches a single character in the subject.  In  UTF-8
+       mode, the character may be more than one byte long. A matched character
+       must be in the set of characters defined by the class, unless the first
+       character  in  the  class definition is a circumflex, in which case the
+       subject character must not be in the set defined by  the  class.  If  a
+       circumflex  is actually required as a member of the class, ensure it is
+       not the first character, or escape it with a backslash.
+
+       For example, the character class [aeiou] matches any lower case  vowel,
+       while  [^aeiou]  matches  any character that is not a lower case vowel.
+       Note that a circumflex is just a convenient notation for specifying the
+       characters  that  are in the class by enumerating those that are not. A
+       class that starts with a circumflex is not an assertion; it still  con-
+       sumes  a  character  from the subject string, and therefore it fails if
+       the current pointer is at the end of the string.
+
+       In UTF-8 mode, characters with values greater than 255 can be  included
+       in  a  class as a literal string of bytes, or by using the \x{ escaping
+       mechanism.
+
+       When caseless matching is set, any letters in a  class  represent  both
+       their  upper  case  and lower case versions, so for example, a caseless
+       [aeiou] matches "A" as well as "a", and a caseless  [^aeiou]  does  not
+       match  "A", whereas a caseful version would. In UTF-8 mode, PCRE always
+       understands the concept of case for characters whose  values  are  less
+       than  128, so caseless matching is always possible. For characters with
+       higher values, the concept of case is supported  if  PCRE  is  compiled
+       with  Unicode  property support, but not otherwise.  If you want to use
+       caseless matching in UTF8-mode for characters 128 and above,  you  must
+       ensure  that  PCRE is compiled with Unicode property support as well as
+       with UTF-8 support.
+
+       Characters that might indicate line breaks are  never  treated  in  any
+       special  way  when  matching  character  classes,  whatever line-ending
+       sequence is in  use,  and  whatever  setting  of  the  PCRE_DOTALL  and
+       PCRE_MULTILINE options is used. A class such as [^a] always matches one
+       of these characters.
+
+       The minus (hyphen) character can be used to specify a range of  charac-
+       ters  in  a  character  class.  For  example,  [d-m] matches any letter
+       between d and m, inclusive. If a  minus  character  is  required  in  a
+       class,  it  must  be  escaped  with a backslash or appear in a position
+       where it cannot be interpreted as indicating a range, typically as  the
+       first or last character in the class.
+
+       It is not possible to have the literal character "]" as the end charac-
+       ter of a range. A pattern such as [W-]46] is interpreted as a class  of
+       two  characters ("W" and "-") followed by a literal string "46]", so it
+       would match "W46]" or "-46]". However, if the "]"  is  escaped  with  a
+       backslash  it is interpreted as the end of range, so [W-\]46] is inter-
+       preted as a class containing a range followed by two other  characters.
+       The  octal or hexadecimal representation of "]" can also be used to end
+       a range.
+
+       Ranges operate in the collating sequence of character values. They  can
+       also   be  used  for  characters  specified  numerically,  for  example
+       [\000-\037]. In UTF-8 mode, ranges can include characters whose  values
+       are greater than 255, for example [\x{100}-\x{2ff}].
+
+       If a range that includes letters is used when caseless matching is set,
+       it matches the letters in either case. For example, [W-c] is equivalent
+       to  [][\\^_`wxyzabc],  matched  caselessly,  and  in non-UTF-8 mode, if
+       character tables for a French locale are in  use,  [\xc8-\xcb]  matches
+       accented  E  characters in both cases. In UTF-8 mode, PCRE supports the
+       concept of case for characters with values greater than 128  only  when
+       it is compiled with Unicode property support.
+
+       The  character types \d, \D, \p, \P, \s, \S, \w, and \W may also appear
+       in a character class, and add the characters that  they  match  to  the
+       class. For example, [\dABCDEF] matches any hexadecimal digit. A circum-
+       flex can conveniently be used with the upper case  character  types  to
+       specify  a  more  restricted  set of characters than the matching lower
+       case type. For example, the class [^\W_] matches any letter  or  digit,
+       but not underscore.
+
+       The  only  metacharacters  that are recognized in character classes are
+       backslash, hyphen (only where it can be  interpreted  as  specifying  a
+       range),  circumflex  (only  at the start), opening square bracket (only
+       when it can be interpreted as introducing a POSIX class name - see  the
+       next  section),  and  the  terminating closing square bracket. However,
+       escaping other non-alphanumeric characters does no harm.
+
+
+POSIX CHARACTER CLASSES
+
+       Perl supports the POSIX notation for character classes. This uses names
+       enclosed  by  [: and :] within the enclosing square brackets. PCRE also
+       supports this notation. For example,
+
+         [01[:alpha:]%]
+
+       matches "0", "1", any alphabetic character, or "%". The supported class
+       names are
+
+         alnum    letters and digits
+         alpha    letters
+         ascii    character codes 0 - 127
+         blank    space or tab only
+         cntrl    control characters
+         digit    decimal digits (same as \d)
+         graph    printing characters, excluding space
+         lower    lower case letters
+         print    printing characters, including space
+         punct    printing characters, excluding letters and digits
+         space    white space (not quite the same as \s)
+         upper    upper case letters
+         word     "word" characters (same as \w)
+         xdigit   hexadecimal digits
+
+       The  "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13),
+       and space (32). Notice that this list includes the VT  character  (code
+       11). This makes "space" different to \s, which does not include VT (for
+       Perl compatibility).
+
+       The name "word" is a Perl extension, and "blank"  is  a  GNU  extension
+       from  Perl  5.8. Another Perl extension is negation, which is indicated
+       by a ^ character after the colon. For example,
+
+         [12[:^digit:]]
+
+       matches "1", "2", or any non-digit. PCRE (and Perl) also recognize  the
+       POSIX syntax [.ch.] and [=ch=] where "ch" is a "collating element", but
+       these are not supported, and an error is given if they are encountered.
+
+       In UTF-8 mode, characters with values greater than 128 do not match any
+       of the POSIX character classes.
+
+
+VERTICAL BAR
+
+       Vertical  bar characters are used to separate alternative patterns. For
+       example, the pattern
+
+         gilbert|sullivan
+
+       matches either "gilbert" or "sullivan". Any number of alternatives  may
+       appear,  and  an  empty  alternative  is  permitted (matching the empty
+       string). The matching process tries each alternative in turn, from left
+       to  right, and the first one that succeeds is used. If the alternatives
+       are within a subpattern (defined below), "succeeds" means matching  the
+       rest of the main pattern as well as the alternative in the subpattern.
+
+
+INTERNAL OPTION SETTING
+
+       The  settings  of  the  PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and
+       PCRE_EXTENDED options (which are Perl-compatible) can be  changed  from
+       within  the  pattern  by  a  sequence  of  Perl option letters enclosed
+       between "(?" and ")".  The option letters are
+
+         i  for PCRE_CASELESS
+         m  for PCRE_MULTILINE
+         s  for PCRE_DOTALL
+         x  for PCRE_EXTENDED
+
+       For example, (?im) sets caseless, multiline matching. It is also possi-
+       ble to unset these options by preceding the letter with a hyphen, and a
+       combined setting and unsetting such as (?im-sx), which sets  PCRE_CASE-
+       LESS  and PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED,
+       is also permitted. If a  letter  appears  both  before  and  after  the
+       hyphen, the option is unset.
+
+       The  PCRE-specific options PCRE_DUPNAMES, PCRE_UNGREEDY, and PCRE_EXTRA
+       can be changed in the same way as the Perl-compatible options by  using
+       the characters J, U and X respectively.
+
+       When  one  of  these  option  changes occurs at top level (that is, not
+       inside subpattern parentheses), the change applies to the remainder  of
+       the pattern that follows. If the change is placed right at the start of
+       a pattern, PCRE extracts it into the global options (and it will there-
+       fore show up in data extracted by the pcre_fullinfo() function).
+
+       An  option  change  within a subpattern (see below for a description of
+       subpatterns) affects only that part of the current pattern that follows
+       it, so
+
+         (a(?i)b)c
+
+       matches abc and aBc and no other strings (assuming PCRE_CASELESS is not
+       used).  By this means, options can be made to have  different  settings
+       in  different parts of the pattern. Any changes made in one alternative
+       do carry on into subsequent branches within the  same  subpattern.  For
+       example,
+
+         (a(?i)b|c)
+
+       matches  "ab",  "aB",  "c",  and "C", even though when matching "C" the
+       first branch is abandoned before the option setting.  This  is  because
+       the  effects  of option settings happen at compile time. There would be
+       some very weird behaviour otherwise.
+
+       Note: There are other PCRE-specific options that  can  be  set  by  the
+       application  when  the  compile  or match functions are called. In some
+       cases the pattern can contain special leading sequences such as (*CRLF)
+       to  override  what  the application has set or what has been defaulted.
+       Details are given in the section entitled  "Newline  sequences"  above.
+       There  is  also  the  (*UTF8)  leading sequence that can be used to set
+       UTF-8 mode; this is equivalent to setting the PCRE_UTF8 option.
+
+
+SUBPATTERNS
+
+       Subpatterns are delimited by parentheses (round brackets), which can be
+       nested.  Turning part of a pattern into a subpattern does two things:
+
+       1. It localizes a set of alternatives. For example, the pattern
+
+         cat(aract|erpillar|)
+
+       matches  one  of the words "cat", "cataract", or "caterpillar". Without
+       the parentheses, it would match  "cataract",  "erpillar"  or  an  empty
+       string.
+
+       2.  It  sets  up  the  subpattern as a capturing subpattern. This means
+       that, when the whole pattern  matches,  that  portion  of  the  subject
+       string that matched the subpattern is passed back to the caller via the
+       ovector argument of pcre_exec(). Opening parentheses are  counted  from
+       left  to  right  (starting  from 1) to obtain numbers for the capturing
+       subpatterns.
+
+       For example, if the string "the red king" is matched against  the  pat-
+       tern
+
+         the ((red|white) (king|queen))
+
+       the captured substrings are "red king", "red", and "king", and are num-
+       bered 1, 2, and 3, respectively.
+
+       The fact that plain parentheses fulfil  two  functions  is  not  always
+       helpful.   There are often times when a grouping subpattern is required
+       without a capturing requirement. If an opening parenthesis is  followed
+       by  a question mark and a colon, the subpattern does not do any captur-
+       ing, and is not counted when computing the  number  of  any  subsequent
+       capturing  subpatterns. For example, if the string "the white queen" is
+       matched against the pattern
+
+         the ((?:red|white) (king|queen))
+
+       the captured substrings are "white queen" and "queen", and are numbered
+       1 and 2. The maximum number of capturing subpatterns is 65535.
+
+       As  a  convenient shorthand, if any option settings are required at the
+       start of a non-capturing subpattern,  the  option  letters  may  appear
+       between the "?" and the ":". Thus the two patterns
+
+         (?i:saturday|sunday)
+         (?:(?i)saturday|sunday)
+
+       match exactly the same set of strings. Because alternative branches are
+       tried from left to right, and options are not reset until  the  end  of
+       the  subpattern is reached, an option setting in one branch does affect
+       subsequent branches, so the above patterns match "SUNDAY"  as  well  as
+       "Saturday".
+
+
+DUPLICATE SUBPATTERN NUMBERS
+
+       Perl 5.10 introduced a feature whereby each alternative in a subpattern
+       uses the same numbers for its capturing parentheses. Such a  subpattern
+       starts  with (?| and is itself a non-capturing subpattern. For example,
+       consider this pattern:
+
+         (?|(Sat)ur|(Sun))day
+
+       Because the two alternatives are inside a (?| group, both sets of  cap-
+       turing  parentheses  are  numbered one. Thus, when the pattern matches,
+       you can look at captured substring number  one,  whichever  alternative
+       matched.  This  construct  is useful when you want to capture part, but
+       not all, of one of a number of alternatives. Inside a (?| group, paren-
+       theses  are  numbered as usual, but the number is reset at the start of
+       each branch. The numbers of any capturing buffers that follow the  sub-
+       pattern  start after the highest number used in any branch. The follow-
+       ing example is taken from the Perl documentation.  The  numbers  under-
+       neath show in which buffer the captured content will be stored.
+
+         # before  ---------------branch-reset----------- after
+         / ( a )  (?| x ( y ) z | (p (q) r) | (t) u (v) ) ( z ) /x
+         # 1            2         2  3        2     3     4
+
+       A  backreference  to  a  numbered subpattern uses the most recent value
+       that is set for that number by any subpattern.  The  following  pattern
+       matches "abcabc" or "defdef":
+
+         /(?|(abc)|(def))\1/
+
+       In  contrast, a recursive or "subroutine" call to a numbered subpattern
+       always refers to the first one in the pattern with  the  given  number.
+       The following pattern matches "abcabc" or "defabc":
+
+         /(?|(abc)|(def))(?1)/
+
+       If  a condition test for a subpattern's having matched refers to a non-
+       unique number, the test is true if any of the subpatterns of that  num-
+       ber have matched.
+
+       An  alternative approach to using this "branch reset" feature is to use
+       duplicate named subpatterns, as described in the next section.
+
+
+NAMED SUBPATTERNS
+
+       Identifying capturing parentheses by number is simple, but  it  can  be
+       very  hard  to keep track of the numbers in complicated regular expres-
+       sions. Furthermore, if an  expression  is  modified,  the  numbers  may
+       change.  To help with this difficulty, PCRE supports the naming of sub-
+       patterns. This feature was not added to Perl until release 5.10. Python
+       had  the  feature earlier, and PCRE introduced it at release 4.0, using
+       the Python syntax. PCRE now supports both the Perl and the Python  syn-
+       tax.  Perl  allows  identically  numbered subpatterns to have different
+       names, but PCRE does not.
+
+       In PCRE, a subpattern can be named in one of three  ways:  (?...)
+       or  (?'name'...)  as in Perl, or (?P...) as in Python. References
+       to capturing parentheses from other parts of the pattern, such as back-
+       references,  recursion,  and conditions, can be made by name as well as
+       by number.
+
+       Names consist of up to  32  alphanumeric  characters  and  underscores.
+       Named  capturing  parentheses  are  still  allocated numbers as well as
+       names, exactly as if the names were not present. The PCRE API  provides
+       function calls for extracting the name-to-number translation table from
+       a compiled pattern. There is also a convenience function for extracting
+       a captured substring by name.
+
+       By  default, a name must be unique within a pattern, but it is possible
+       to relax this constraint by setting the PCRE_DUPNAMES option at compile
+       time.  (Duplicate  names are also always permitted for subpatterns with
+       the same number, set up as described in the previous  section.)  Dupli-
+       cate  names  can  be useful for patterns where only one instance of the
+       named parentheses can match. Suppose you want to match the  name  of  a
+       weekday,  either as a 3-letter abbreviation or as the full name, and in
+       both cases you want to extract the abbreviation. This pattern (ignoring
+       the line breaks) does the job:
+
+         (?Mon|Fri|Sun)(?:day)?|
+         (?Tue)(?:sday)?|
+         (?Wed)(?:nesday)?|
+         (?Thu)(?:rsday)?|
+         (?Sat)(?:urday)?
+
+       There  are  five capturing substrings, but only one is ever set after a
+       match.  (An alternative way of solving this problem is to use a "branch
+       reset" subpattern, as described in the previous section.)
+
+       The  convenience  function  for extracting the data by name returns the
+       substring for the first (and in this example, the only)  subpattern  of
+       that  name  that  matched.  This saves searching to find which numbered
+       subpattern it was.
+
+       If you make a backreference to a non-unique named subpattern from else-
+       where  in the pattern, the one that corresponds to the first occurrence
+       of the name is used. In the absence of duplicate numbers (see the  pre-
+       vious  section)  this  is  the one with the lowest number. If you use a
+       named reference in a condition test (see the section  about  conditions
+       below),  either  to check whether a subpattern has matched, or to check
+       for recursion, all subpatterns with the same name are  tested.  If  the
+       condition  is  true for any one of them, the overall condition is true.
+       This is the same behaviour as testing by number. For further details of
+       the interfaces for handling named subpatterns, see the pcreapi documen-
+       tation.
+
+       Warning: You cannot use different names to distinguish between two sub-
+       patterns  with  the same number because PCRE uses only the numbers when
+       matching. For this reason, an error is given at compile time if differ-
+       ent  names  are given to subpatterns with the same number. However, you
+       can give the same name to subpatterns with the same number,  even  when
+       PCRE_DUPNAMES is not set.
+
+
+REPETITION
+
+       Repetition  is  specified  by  quantifiers, which can follow any of the
+       following items:
+
+         a literal data character
+         the dot metacharacter
+         the \C escape sequence
+         the \X escape sequence (in UTF-8 mode with Unicode properties)
+         the \R escape sequence
+         an escape such as \d that matches a single character
+         a character class
+         a back reference (see next section)
+         a parenthesized subpattern (unless it is an assertion)
+         a recursive or "subroutine" call to a subpattern
+
+       The general repetition quantifier specifies a minimum and maximum  num-
+       ber  of  permitted matches, by giving the two numbers in curly brackets
+       (braces), separated by a comma. The numbers must be  less  than  65536,
+       and the first must be less than or equal to the second. For example:
+
+         z{2,4}
+
+       matches  "zz",  "zzz",  or  "zzzz". A closing brace on its own is not a
+       special character. If the second number is omitted, but  the  comma  is
+       present,  there  is  no upper limit; if the second number and the comma
+       are both omitted, the quantifier specifies an exact number of  required
+       matches. Thus
+
+         [aeiou]{3,}
+
+       matches at least 3 successive vowels, but may match many more, while
+
+         \d{8}
+
+       matches  exactly  8  digits. An opening curly bracket that appears in a
+       position where a quantifier is not allowed, or one that does not  match
+       the  syntax of a quantifier, is taken as a literal character. For exam-
+       ple, {,6} is not a quantifier, but a literal string of four characters.
+
+       In UTF-8 mode, quantifiers apply to UTF-8  characters  rather  than  to
+       individual bytes. Thus, for example, \x{100}{2} matches two UTF-8 char-
+       acters, each of which is represented by a two-byte sequence. Similarly,
+       when Unicode property support is available, \X{3} matches three Unicode
+       extended sequences, each of which may be several bytes long  (and  they
+       may be of different lengths).
+
+       The quantifier {0} is permitted, causing the expression to behave as if
+       the previous item and the quantifier were not present. This may be use-
+       ful  for  subpatterns that are referenced as subroutines from elsewhere
+       in the pattern. Items other than subpatterns that have a {0} quantifier
+       are omitted from the compiled pattern.
+
+       For  convenience, the three most common quantifiers have single-charac-
+       ter abbreviations:
+
+         *    is equivalent to {0,}
+         +    is equivalent to {1,}
+         ?    is equivalent to {0,1}
+
+       It is possible to construct infinite loops by  following  a  subpattern
+       that can match no characters with a quantifier that has no upper limit,
+       for example:
+
+         (a?)*
+
+       Earlier versions of Perl and PCRE used to give an error at compile time
+       for  such  patterns. However, because there are cases where this can be
+       useful, such patterns are now accepted, but if any  repetition  of  the
+       subpattern  does in fact match no characters, the loop is forcibly bro-
+       ken.
+
+       By default, the quantifiers are "greedy", that is, they match  as  much
+       as  possible  (up  to  the  maximum number of permitted times), without
+       causing the rest of the pattern to fail. The classic example  of  where
+       this gives problems is in trying to match comments in C programs. These
+       appear between /* and */ and within the comment,  individual  *  and  /
+       characters  may  appear. An attempt to match C comments by applying the
+       pattern
+
+         /\*.*\*/
+
+       to the string
+
+         /* first comment */  not comment  /* second comment */
+
+       fails, because it matches the entire string owing to the greediness  of
+       the .*  item.
+
+       However,  if  a quantifier is followed by a question mark, it ceases to
+       be greedy, and instead matches the minimum number of times possible, so
+       the pattern
+
+         /\*.*?\*/
+
+       does  the  right  thing with the C comments. The meaning of the various
+       quantifiers is not otherwise changed,  just  the  preferred  number  of
+       matches.   Do  not  confuse this use of question mark with its use as a
+       quantifier in its own right. Because it has two uses, it can  sometimes
+       appear doubled, as in
+
+         \d??\d
+
+       which matches one digit by preference, but can match two if that is the
+       only way the rest of the pattern matches.
+
+       If the PCRE_UNGREEDY option is set (an option that is not available  in
+       Perl),  the  quantifiers are not greedy by default, but individual ones
+       can be made greedy by following them with a  question  mark.  In  other
+       words, it inverts the default behaviour.
+
+       When  a  parenthesized  subpattern  is quantified with a minimum repeat
+       count that is greater than 1 or with a limited maximum, more memory  is
+       required  for  the  compiled  pattern, in proportion to the size of the
+       minimum or maximum.
+
+       If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equiv-
+       alent  to  Perl's  /s) is set, thus allowing the dot to match newlines,
+       the pattern is implicitly anchored, because whatever  follows  will  be
+       tried  against every character position in the subject string, so there
+       is no point in retrying the overall match at  any  position  after  the
+       first.  PCRE  normally treats such a pattern as though it were preceded
+       by \A.
+
+       In cases where it is known that the subject  string  contains  no  new-
+       lines,  it  is  worth setting PCRE_DOTALL in order to obtain this opti-
+       mization, or alternatively using ^ to indicate anchoring explicitly.
+
+       However, there is one situation where the optimization cannot be  used.
+       When  .*   is  inside  capturing  parentheses that are the subject of a
+       backreference elsewhere in the pattern, a match at the start  may  fail
+       where a later one succeeds. Consider, for example:
+
+         (.*)abc\1
+
+       If  the subject is "xyz123abc123" the match point is the fourth charac-
+       ter. For this reason, such a pattern is not implicitly anchored.
+
+       When a capturing subpattern is repeated, the value captured is the sub-
+       string that matched the final iteration. For example, after
+
+         (tweedle[dume]{3}\s*)+
+
+       has matched "tweedledum tweedledee" the value of the captured substring
+       is "tweedledee". However, if there are  nested  capturing  subpatterns,
+       the  corresponding captured values may have been set in previous itera-
+       tions. For example, after
+
+         /(a|(b))+/
+
+       matches "aba" the value of the second captured substring is "b".
+
+
+ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS
+
+       With both maximizing ("greedy") and minimizing ("ungreedy"  or  "lazy")
+       repetition,  failure  of what follows normally causes the repeated item
+       to be re-evaluated to see if a different number of repeats  allows  the
+       rest  of  the pattern to match. Sometimes it is useful to prevent this,
+       either to change the nature of the match, or to cause it  fail  earlier
+       than  it otherwise might, when the author of the pattern knows there is
+       no point in carrying on.
+
+       Consider, for example, the pattern \d+foo when applied to  the  subject
+       line
+
+         123456bar
+
+       After matching all 6 digits and then failing to match "foo", the normal
+       action of the matcher is to try again with only 5 digits  matching  the
+       \d+  item,  and  then  with  4,  and  so on, before ultimately failing.
+       "Atomic grouping" (a term taken from Jeffrey  Friedl's  book)  provides
+       the  means for specifying that once a subpattern has matched, it is not
+       to be re-evaluated in this way.
+
+       If we use atomic grouping for the previous example, the  matcher  gives
+       up  immediately  on failing to match "foo" the first time. The notation
+       is a kind of special parenthesis, starting with (?> as in this example:
+
+         (?>\d+)foo
+
+       This kind of parenthesis "locks up" the  part of the  pattern  it  con-
+       tains  once  it  has matched, and a failure further into the pattern is
+       prevented from backtracking into it. Backtracking past it  to  previous
+       items, however, works as normal.
+
+       An  alternative  description  is that a subpattern of this type matches
+       the string of characters that an  identical  standalone  pattern  would
+       match, if anchored at the current point in the subject string.
+
+       Atomic grouping subpatterns are not capturing subpatterns. Simple cases
+       such as the above example can be thought of as a maximizing repeat that
+       must  swallow  everything  it can. So, while both \d+ and \d+? are pre-
+       pared to adjust the number of digits they match in order  to  make  the
+       rest of the pattern match, (?>\d+) can only match an entire sequence of
+       digits.
+
+       Atomic groups in general can of course contain arbitrarily  complicated
+       subpatterns,  and  can  be  nested. However, when the subpattern for an
+       atomic group is just a single repeated item, as in the example above, a
+       simpler  notation,  called  a "possessive quantifier" can be used. This
+       consists of an additional + character  following  a  quantifier.  Using
+       this notation, the previous example can be rewritten as
+
+         \d++foo
+
+       Note that a possessive quantifier can be used with an entire group, for
+       example:
+
+         (abc|xyz){2,3}+
+
+       Possessive  quantifiers  are  always  greedy;  the   setting   of   the
+       PCRE_UNGREEDY option is ignored. They are a convenient notation for the
+       simpler forms of atomic group. However, there is no difference  in  the
+       meaning  of  a  possessive  quantifier and the equivalent atomic group,
+       though there may be a performance  difference;  possessive  quantifiers
+       should be slightly faster.
+
+       The  possessive  quantifier syntax is an extension to the Perl 5.8 syn-
+       tax.  Jeffrey Friedl originated the idea (and the name)  in  the  first
+       edition of his book. Mike McCloskey liked it, so implemented it when he
+       built Sun's Java package, and PCRE copied it from there. It  ultimately
+       found its way into Perl at release 5.10.
+
+       PCRE has an optimization that automatically "possessifies" certain sim-
+       ple pattern constructs. For example, the sequence  A+B  is  treated  as
+       A++B  because  there is no point in backtracking into a sequence of A's
+       when B must follow.
+
+       When a pattern contains an unlimited repeat inside  a  subpattern  that
+       can  itself  be  repeated  an  unlimited number of times, the use of an
+       atomic group is the only way to avoid some  failing  matches  taking  a
+       very long time indeed. The pattern
+
+         (\D+|<\d+>)*[!?]
+
+       matches  an  unlimited number of substrings that either consist of non-
+       digits, or digits enclosed in <>, followed by either ! or  ?.  When  it
+       matches, it runs quickly. However, if it is applied to
+
+         aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+
+       it  takes  a  long  time  before reporting failure. This is because the
+       string can be divided between the internal \D+ repeat and the  external
+       *  repeat  in  a  large  number of ways, and all have to be tried. (The
+       example uses [!?] rather than a single character at  the  end,  because
+       both  PCRE  and  Perl have an optimization that allows for fast failure
+       when a single character is used. They remember the last single  charac-
+       ter  that  is required for a match, and fail early if it is not present
+       in the string.) If the pattern is changed so that  it  uses  an  atomic
+       group, like this:
+
+         ((?>\D+)|<\d+>)*[!?]
+
+       sequences of non-digits cannot be broken, and failure happens quickly.
+
+
+BACK REFERENCES
+
+       Outside a character class, a backslash followed by a digit greater than
+       0 (and possibly further digits) is a back reference to a capturing sub-
+       pattern  earlier  (that is, to its left) in the pattern, provided there
+       have been that many previous capturing left parentheses.
+
+       However, if the decimal number following the backslash is less than 10,
+       it  is  always  taken  as a back reference, and causes an error only if
+       there are not that many capturing left parentheses in the  entire  pat-
+       tern.  In  other words, the parentheses that are referenced need not be
+       to the left of the reference for numbers less than 10. A "forward  back
+       reference"  of  this  type can make sense when a repetition is involved
+       and the subpattern to the right has participated in an  earlier  itera-
+       tion.
+
+       It  is  not  possible to have a numerical "forward back reference" to a
+       subpattern whose number is 10 or  more  using  this  syntax  because  a
+       sequence  such  as  \50 is interpreted as a character defined in octal.
+       See the subsection entitled "Non-printing characters" above for further
+       details  of  the  handling of digits following a backslash. There is no
+       such problem when named parentheses are used. A back reference  to  any
+       subpattern is possible using named parentheses (see below).
+
+       Another  way  of  avoiding  the ambiguity inherent in the use of digits
+       following a backslash is to use the \g escape sequence, which is a fea-
+       ture  introduced  in  Perl  5.10.  This  escape  must be followed by an
+       unsigned number or a negative number, optionally  enclosed  in  braces.
+       These examples are all identical:
+
+         (ring), \1
+         (ring), \g1
+         (ring), \g{1}
+
+       An  unsigned number specifies an absolute reference without the ambigu-
+       ity that is present in the older syntax. It is also useful when literal
+       digits follow the reference. A negative number is a relative reference.
+       Consider this example:
+
+         (abc(def)ghi)\g{-1}
+
+       The sequence \g{-1} is a reference to the most recently started captur-
+       ing  subpattern  before \g, that is, is it equivalent to \2. Similarly,
+       \g{-2} would be equivalent to \1. The use of relative references can be
+       helpful  in  long  patterns,  and  also in patterns that are created by
+       joining together fragments that contain references within themselves.
+
+       A back reference matches whatever actually matched the  capturing  sub-
+       pattern  in  the  current subject string, rather than anything matching
+       the subpattern itself (see "Subpatterns as subroutines" below for a way
+       of doing that). So the pattern
+
+         (sens|respons)e and \1ibility
+
+       matches  "sense and sensibility" and "response and responsibility", but
+       not "sense and responsibility". If caseful matching is in force at  the
+       time  of the back reference, the case of letters is relevant. For exam-
+       ple,
+
+         ((?i)rah)\s+\1
+
+       matches "rah rah" and "RAH RAH", but not "RAH  rah",  even  though  the
+       original capturing subpattern is matched caselessly.
+
+       There  are  several  different ways of writing back references to named
+       subpatterns. The .NET syntax \k{name} and the Perl syntax  \k  or
+       \k'name'  are supported, as is the Python syntax (?P=name). Perl 5.10's
+       unified back reference syntax, in which \g can be used for both numeric
+       and  named  references,  is  also supported. We could rewrite the above
+       example in any of the following ways:
+
+         (?(?i)rah)\s+\k
+         (?'p1'(?i)rah)\s+\k{p1}
+         (?P(?i)rah)\s+(?P=p1)
+         (?(?i)rah)\s+\g{p1}
+
+       A subpattern that is referenced by  name  may  appear  in  the  pattern
+       before or after the reference.
+
+       There  may be more than one back reference to the same subpattern. If a
+       subpattern has not actually been used in a particular match,  any  back
+       references to it always fail by default. For example, the pattern
+
+         (a|(bc))\2
+
+       always  fails  if  it starts to match "a" rather than "bc". However, if
+       the PCRE_JAVASCRIPT_COMPAT option is set at compile time, a back refer-
+       ence to an unset value matches an empty string.
+
+       Because  there may be many capturing parentheses in a pattern, all dig-
+       its following a backslash are taken as part of a potential back  refer-
+       ence  number.   If  the  pattern continues with a digit character, some
+       delimiter must  be  used  to  terminate  the  back  reference.  If  the
+       PCRE_EXTENDED option is set, this can be whitespace. Otherwise, the \g{
+       syntax or an empty comment (see "Comments" below) can be used.
+
+       A back reference that occurs inside the parentheses to which it  refers
+       fails  when  the subpattern is first used, so, for example, (a\1) never
+       matches.  However, such references can be useful inside  repeated  sub-
+       patterns. For example, the pattern
+
+         (a|b\1)+
+
+       matches any number of "a"s and also "aba", "ababbaa" etc. At each iter-
+       ation of the subpattern,  the  back  reference  matches  the  character
+       string  corresponding  to  the previous iteration. In order for this to
+       work, the pattern must be such that the first iteration does  not  need
+       to  match the back reference. This can be done using alternation, as in
+       the example above, or by a quantifier with a minimum of zero.
+
+
+ASSERTIONS
+
+       An assertion is a test on the characters  following  or  preceding  the
+       current  matching  point that does not actually consume any characters.
+       The simple assertions coded as \b, \B, \A, \G, \Z,  \z,  ^  and  $  are
+       described above.
+
+       More  complicated  assertions  are  coded as subpatterns. There are two
+       kinds: those that look ahead of the current  position  in  the  subject
+       string,  and  those  that  look  behind  it. An assertion subpattern is
+       matched in the normal way, except that it does not  cause  the  current
+       matching position to be changed.
+
+       Assertion  subpatterns  are  not  capturing subpatterns, and may not be
+       repeated, because it makes no sense to assert the  same  thing  several
+       times.  If  any kind of assertion contains capturing subpatterns within
+       it, these are counted for the purposes of numbering the capturing  sub-
+       patterns in the whole pattern.  However, substring capturing is carried
+       out only for positive assertions, because it does not  make  sense  for
+       negative assertions.
+
+   Lookahead assertions
+
+       Lookahead assertions start with (?= for positive assertions and (?! for
+       negative assertions. For example,
+
+         \w+(?=;)
+
+       matches a word followed by a semicolon, but does not include the  semi-
+       colon in the match, and
+
+         foo(?!bar)
+
+       matches  any  occurrence  of  "foo" that is not followed by "bar". Note
+       that the apparently similar pattern
+
+         (?!foo)bar
+
+       does not find an occurrence of "bar"  that  is  preceded  by  something
+       other  than "foo"; it finds any occurrence of "bar" whatsoever, because
+       the assertion (?!foo) is always true when the next three characters are
+       "bar". A lookbehind assertion is needed to achieve the other effect.
+
+       If you want to force a matching failure at some point in a pattern, the
+       most convenient way to do it is  with  (?!)  because  an  empty  string
+       always  matches, so an assertion that requires there not to be an empty
+       string must always fail.   The  Perl  5.10  backtracking  control  verb
+       (*FAIL) or (*F) is essentially a synonym for (?!).
+
+   Lookbehind assertions
+
+       Lookbehind  assertions start with (?<= for positive assertions and (?)...) or (?('name')...) to test for a
+       used subpattern by name. For compatibility  with  earlier  versions  of
+       PCRE,  which  had this facility before Perl, the syntax (?(name)...) is
+       also recognized. However, there is a possible ambiguity with this  syn-
+       tax,  because  subpattern  names  may  consist entirely of digits. PCRE
+       looks first for a named subpattern; if it cannot find one and the  name
+       consists  entirely  of digits, PCRE looks for a subpattern of that num-
+       ber, which must be greater than zero. Using subpattern names that  con-
+       sist entirely of digits is not recommended.
+
+       Rewriting the above example to use a named subpattern gives this:
+
+         (? \( )?    [^()]+    (?() \) )
+
+       If  the  name used in a condition of this kind is a duplicate, the test
+       is applied to all subpatterns of the same name, and is true if any  one
+       of them has matched.
+
+   Checking for pattern recursion
+
+       If the condition is the string (R), and there is no subpattern with the
+       name R, the condition is true if a recursive call to the whole  pattern
+       or any subpattern has been made. If digits or a name preceded by amper-
+       sand follow the letter R, for example:
+
+         (?(R3)...) or (?(R&name)...)
+
+       the condition is true if the most recent recursion is into a subpattern
+       whose number or name is given. This condition does not check the entire
+       recursion stack. If the name used in a condition  of  this  kind  is  a
+       duplicate, the test is applied to all subpatterns of the same name, and
+       is true if any one of them is the most recent recursion.
+
+       At "top level", all these recursion test  conditions  are  false.   The
+       syntax for recursive patterns is described below.
+
+   Defining subpatterns for use by reference only
+
+       If  the  condition  is  the string (DEFINE), and there is no subpattern
+       with the name DEFINE, the condition is  always  false.  In  this  case,
+       there  may  be  only  one  alternative  in the subpattern. It is always
+       skipped if control reaches this point  in  the  pattern;  the  idea  of
+       DEFINE  is that it can be used to define "subroutines" that can be ref-
+       erenced from elsewhere. (The use of "subroutines" is described  below.)
+       For  example,  a pattern to match an IPv4 address could be written like
+       this (ignore whitespace and line breaks):
+
+         (?(DEFINE) (? 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+         \b (?&byte) (\.(?&byte)){3} \b
+
+       The first part of the pattern is a DEFINE group inside which a  another
+       group  named "byte" is defined. This matches an individual component of
+       an IPv4 address (a number less than 256). When  matching  takes  place,
+       this  part  of  the pattern is skipped because DEFINE acts like a false
+       condition. The rest of the pattern uses references to the  named  group
+       to  match the four dot-separated components of an IPv4 address, insist-
+       ing on a word boundary at each end.
+
+   Assertion conditions
+
+       If the condition is not in any of the above  formats,  it  must  be  an
+       assertion.   This may be a positive or negative lookahead or lookbehind
+       assertion. Consider  this  pattern,  again  containing  non-significant
+       white space, and with the two alternatives on the second line:
+
+         (?(?=[^a-z]*[a-z])
+         \d{2}-[a-z]{3}-\d{2}  |  \d{2}-\d{2}-\d{2} )
+
+       The  condition  is  a  positive  lookahead  assertion  that  matches an
+       optional sequence of non-letters followed by a letter. In other  words,
+       it  tests  for the presence of at least one letter in the subject. If a
+       letter is found, the subject is matched against the first  alternative;
+       otherwise  it  is  matched  against  the  second.  This pattern matches
+       strings in one of the two forms dd-aaa-dd or dd-dd-dd,  where  aaa  are
+       letters and dd are digits.
+
+
+COMMENTS
+
+       The  sequence (?# marks the start of a comment that continues up to the
+       next closing parenthesis. Nested parentheses  are  not  permitted.  The
+       characters  that make up a comment play no part in the pattern matching
+       at all.
+
+       If the PCRE_EXTENDED option is set, an unescaped # character outside  a
+       character  class  introduces  a  comment  that continues to immediately
+       after the next newline in the pattern.
+
+
+RECURSIVE PATTERNS
+
+       Consider the problem of matching a string in parentheses, allowing  for
+       unlimited  nested  parentheses.  Without the use of recursion, the best
+       that can be done is to use a pattern that  matches  up  to  some  fixed
+       depth  of  nesting.  It  is not possible to handle an arbitrary nesting
+       depth.
+
+       For some time, Perl has provided a facility that allows regular expres-
+       sions  to recurse (amongst other things). It does this by interpolating
+       Perl code in the expression at run time, and the code can refer to  the
+       expression itself. A Perl pattern using code interpolation to solve the
+       parentheses problem can be created like this:
+
+         $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
+
+       The (?p{...}) item interpolates Perl code at run time, and in this case
+       refers recursively to the pattern in which it appears.
+
+       Obviously, PCRE cannot support the interpolation of Perl code. Instead,
+       it supports special syntax for recursion of  the  entire  pattern,  and
+       also  for  individual  subpattern  recursion. After its introduction in
+       PCRE and Python, this kind of  recursion  was  subsequently  introduced
+       into Perl at release 5.10.
+
+       A  special  item  that consists of (? followed by a number greater than
+       zero and a closing parenthesis is a recursive call of the subpattern of
+       the  given  number, provided that it occurs inside that subpattern. (If
+       not, it is a "subroutine" call, which is described  in  the  next  sec-
+       tion.)  The special item (?R) or (?0) is a recursive call of the entire
+       regular expression.
+
+       This PCRE pattern solves the nested  parentheses  problem  (assume  the
+       PCRE_EXTENDED option is set so that white space is ignored):
+
+         \( ( [^()]++ | (?R) )* \)
+
+       First  it matches an opening parenthesis. Then it matches any number of
+       substrings which can either be a  sequence  of  non-parentheses,  or  a
+       recursive  match  of the pattern itself (that is, a correctly parenthe-
+       sized substring).  Finally there is a closing parenthesis. Note the use
+       of a possessive quantifier to avoid backtracking into sequences of non-
+       parentheses.
+
+       If this were part of a larger pattern, you would not  want  to  recurse
+       the entire pattern, so instead you could use this:
+
+         ( \( ( [^()]++ | (?1) )* \) )
+
+       We  have  put the pattern into parentheses, and caused the recursion to
+       refer to them instead of the whole pattern.
+
+       In a larger pattern,  keeping  track  of  parenthesis  numbers  can  be
+       tricky.  This  is made easier by the use of relative references (a Perl
+       5.10 feature).  Instead of (?1) in the  pattern  above  you  can  write
+       (?-2) to refer to the second most recently opened parentheses preceding
+       the recursion. In other  words,  a  negative  number  counts  capturing
+       parentheses leftwards from the point at which it is encountered.
+
+       It  is  also  possible  to refer to subsequently opened parentheses, by
+       writing references such as (?+2). However, these  cannot  be  recursive
+       because  the  reference  is  not inside the parentheses that are refer-
+       enced. They are always "subroutine" calls, as  described  in  the  next
+       section.
+
+       An  alternative  approach is to use named parentheses instead. The Perl
+       syntax for this is (?&name); PCRE's earlier syntax  (?P>name)  is  also
+       supported. We could rewrite the above example as follows:
+
+         (? \( ( [^()]++ | (?&pn) )* \) )
+
+       If  there  is more than one subpattern with the same name, the earliest
+       one is used.
+
+       This particular example pattern that we have been looking  at  contains
+       nested unlimited repeats, and so the use of a possessive quantifier for
+       matching strings of non-parentheses is important when applying the pat-
+       tern  to  strings  that do not match. For example, when this pattern is
+       applied to
+
+         (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+
+       it yields "no match" quickly. However, if a  possessive  quantifier  is
+       not  used, the match runs for a very long time indeed because there are
+       so many different ways the + and * repeats can carve  up  the  subject,
+       and all have to be tested before failure can be reported.
+
+       At  the  end  of a match, the values of capturing parentheses are those
+       from the outermost level. If you want to obtain intermediate values,  a
+       callout  function can be used (see below and the pcrecallout documenta-
+       tion). If the pattern above is matched against
+
+         (ab(cd)ef)
+
+       the value for the inner capturing parentheses  (numbered  2)  is  "ef",
+       which  is the last value taken on at the top level. If a capturing sub-
+       pattern is not matched at the top level, its final value is unset, even
+       if it is (temporarily) set at a deeper level.
+
+       If  there are more than 15 capturing parentheses in a pattern, PCRE has
+       to obtain extra memory to store data during a recursion, which it  does
+       by using pcre_malloc, freeing it via pcre_free afterwards. If no memory
+       can be obtained, the match fails with the PCRE_ERROR_NOMEMORY error.
+
+       Do not confuse the (?R) item with the condition (R),  which  tests  for
+       recursion.   Consider  this pattern, which matches text in angle brack-
+       ets, allowing for arbitrary nesting. Only digits are allowed in  nested
+       brackets  (that is, when recursing), whereas any characters are permit-
+       ted at the outer level.
+
+         < (?: (?(R) \d++  | [^<>]*+) | (?R)) * >
+
+       In this pattern, (?(R) is the start of a conditional  subpattern,  with
+       two  different  alternatives for the recursive and non-recursive cases.
+       The (?R) item is the actual recursive call.
+
+   Recursion difference from Perl
+
+       In PCRE (like Python, but unlike Perl), a recursive subpattern call  is
+       always treated as an atomic group. That is, once it has matched some of
+       the subject string, it is never re-entered, even if it contains untried
+       alternatives  and  there  is a subsequent matching failure. This can be
+       illustrated by the following pattern, which purports to match a  palin-
+       dromic  string  that contains an odd number of characters (for example,
+       "a", "aba", "abcba", "abcdcba"):
+
+         ^(.|(.)(?1)\2)$
+
+       The idea is that it either matches a single character, or two identical
+       characters  surrounding  a sub-palindrome. In Perl, this pattern works;
+       in PCRE it does not if the pattern is  longer  than  three  characters.
+       Consider the subject string "abcba":
+
+       At  the  top level, the first character is matched, but as it is not at
+       the end of the string, the first alternative fails; the second alterna-
+       tive is taken and the recursion kicks in. The recursive call to subpat-
+       tern 1 successfully matches the next character ("b").  (Note  that  the
+       beginning and end of line tests are not part of the recursion).
+
+       Back  at  the top level, the next character ("c") is compared with what
+       subpattern 2 matched, which was "a". This fails. Because the  recursion
+       is  treated  as  an atomic group, there are now no backtracking points,
+       and so the entire match fails. (Perl is able, at  this  point,  to  re-
+       enter  the  recursion  and try the second alternative.) However, if the
+       pattern is written with the alternatives in the other order, things are
+       different:
+
+         ^((.)(?1)\2|.)$
+
+       This  time,  the recursing alternative is tried first, and continues to
+       recurse until it runs out of characters, at which point  the  recursion
+       fails.  But  this  time  we  do  have another alternative to try at the
+       higher level. That is the big difference:  in  the  previous  case  the
+       remaining alternative is at a deeper recursion level, which PCRE cannot
+       use.
+
+       To change the pattern so that matches all palindromic strings, not just
+       those  with  an  odd number of characters, it is tempting to change the
+       pattern to this:
+
+         ^((.)(?1)\2|.?)$
+
+       Again, this works in Perl, but not in PCRE, and for  the  same  reason.
+       When  a  deeper  recursion has matched a single character, it cannot be
+       entered again in order to match an empty string.  The  solution  is  to
+       separate  the two cases, and write out the odd and even cases as alter-
+       natives at the higher level:
+
+         ^(?:((.)(?1)\2|)|((.)(?3)\4|.))
+
+       If you want to match typical palindromic phrases, the  pattern  has  to
+       ignore all non-word characters, which can be done like this:
+
+         ^\W*+(?:((.)\W*+(?1)\W*+\2|)|((.)\W*+(?3)\W*+\4|\W*+.\W*+))\W*+$
+
+       If run with the PCRE_CASELESS option, this pattern matches phrases such
+       as "A man, a plan, a canal: Panama!" and it works well in both PCRE and
+       Perl.  Note the use of the possessive quantifier *+ to avoid backtrack-
+       ing into sequences of non-word characters. Without this, PCRE  takes  a
+       great  deal  longer  (ten  times or more) to match typical phrases, and
+       Perl takes so long that you think it has gone into a loop.
+
+       WARNING: The palindrome-matching patterns above work only if  the  sub-
+       ject  string  does not start with a palindrome that is shorter than the
+       entire string.  For example, although "abcba" is correctly matched,  if
+       the  subject  is "ababa", PCRE finds the palindrome "aba" at the start,
+       then fails at top level because the end of the string does not  follow.
+       Once  again, it cannot jump back into the recursion to try other alter-
+       natives, so the entire match fails.
+
+
+SUBPATTERNS AS SUBROUTINES
+
+       If the syntax for a recursive subpattern reference (either by number or
+       by  name)  is used outside the parentheses to which it refers, it oper-
+       ates like a subroutine in a programming language. The "called"  subpat-
+       tern may be defined before or after the reference. A numbered reference
+       can be absolute or relative, as in these examples:
+
+         (...(absolute)...)...(?2)...
+         (...(relative)...)...(?-1)...
+         (...(?+1)...(relative)...
+
+       An earlier example pointed out that the pattern
+
+         (sens|respons)e and \1ibility
+
+       matches "sense and sensibility" and "response and responsibility",  but
+       not "sense and responsibility". If instead the pattern
+
+         (sens|respons)e and (?1)ibility
+
+       is  used, it does match "sense and responsibility" as well as the other
+       two strings. Another example is  given  in  the  discussion  of  DEFINE
+       above.
+
+       Like  recursive  subpatterns, a subroutine call is always treated as an
+       atomic group. That is, once it has matched some of the subject  string,
+       it  is  never  re-entered, even if it contains untried alternatives and
+       there is a subsequent matching failure. Any capturing parentheses  that
+       are  set  during  the  subroutine  call revert to their previous values
+       afterwards.
+
+       When a subpattern is used as a subroutine, processing options  such  as
+       case-independence are fixed when the subpattern is defined. They cannot
+       be changed for different calls. For example, consider this pattern:
+
+         (abc)(?i:(?-1))
+
+       It matches "abcabc". It does not match "abcABC" because the  change  of
+       processing option does not affect the called subpattern.
+
+
+ONIGURUMA SUBROUTINE SYNTAX
+
+       For  compatibility with Oniguruma, the non-Perl syntax \g followed by a
+       name or a number enclosed either in angle brackets or single quotes, is
+       an  alternative  syntax  for  referencing a subpattern as a subroutine,
+       possibly recursively. Here are two of the examples used above,  rewrit-
+       ten using this syntax:
+
+         (? \( ( (?>[^()]+) | \g )* \) )
+         (sens|respons)e and \g'1'ibility
+
+       PCRE  supports  an extension to Oniguruma: if a number is preceded by a
+       plus or a minus sign it is taken as a relative reference. For example:
+
+         (abc)(?i:\g<-1>)
+
+       Note that \g{...} (Perl syntax) and \g<...> (Oniguruma syntax) are  not
+       synonymous.  The former is a back reference; the latter is a subroutine
+       call.
+
+
+CALLOUTS
+
+       Perl has a feature whereby using the sequence (?{...}) causes arbitrary
+       Perl  code to be obeyed in the middle of matching a regular expression.
+       This makes it possible, amongst other things, to extract different sub-
+       strings that match the same pair of parentheses when there is a repeti-
+       tion.
+
+       PCRE provides a similar feature, but of course it cannot obey arbitrary
+       Perl code. The feature is called "callout". The caller of PCRE provides
+       an external function by putting its entry point in the global  variable
+       pcre_callout.   By default, this variable contains NULL, which disables
+       all calling out.
+
+       Within a regular expression, (?C) indicates the  points  at  which  the
+       external  function  is  to be called. If you want to identify different
+       callout points, you can put a number less than 256 after the letter  C.
+       The  default  value is zero.  For example, this pattern has two callout
+       points:
+
+         (?C1)abc(?C2)def
+
+       If the PCRE_AUTO_CALLOUT flag is passed to pcre_compile(), callouts are
+       automatically  installed  before each item in the pattern. They are all
+       numbered 255.
+
+       During matching, when PCRE reaches a callout point (and pcre_callout is
+       set),  the  external function is called. It is provided with the number
+       of the callout, the position in the pattern, and, optionally, one  item
+       of  data  originally supplied by the caller of pcre_exec(). The callout
+       function may cause matching to proceed, to backtrack, or to fail  alto-
+       gether. A complete description of the interface to the callout function
+       is given in the pcrecallout documentation.
+
+
+BACKTRACKING CONTROL
+
+       Perl 5.10 introduced a number of "Special Backtracking Control  Verbs",
+       which are described in the Perl documentation as "experimental and sub-
+       ject to change or removal in a future version of Perl". It goes  on  to
+       say:  "Their usage in production code should be noted to avoid problems
+       during upgrades." The same remarks apply to the PCRE features described
+       in this section.
+
+       Since  these  verbs  are  specifically related to backtracking, most of
+       them can be  used  only  when  the  pattern  is  to  be  matched  using
+       pcre_exec(), which uses a backtracking algorithm. With the exception of
+       (*FAIL), which behaves like a failing negative assertion, they cause an
+       error if encountered by pcre_dfa_exec().
+
+       If any of these verbs are used in an assertion or subroutine subpattern
+       (including recursive subpatterns), their effect  is  confined  to  that
+       subpattern;  it  does  not extend to the surrounding pattern. Note that
+       such subpatterns are processed as anchored at the point where they  are
+       tested.
+
+       The  new verbs make use of what was previously invalid syntax: an open-
+       ing parenthesis followed by an asterisk. In Perl, they are generally of
+       the form (*VERB:ARG) but PCRE does not support the use of arguments, so
+       its general form is just (*VERB). Any number of these verbs  may  occur
+       in a pattern. There are two kinds:
+
+   Verbs that act immediately
+
+       The following verbs act as soon as they are encountered:
+
+          (*ACCEPT)
+
+       This  verb causes the match to end successfully, skipping the remainder
+       of the pattern. When inside a recursion, only the innermost pattern  is
+       ended  immediately.  If  (*ACCEPT) is inside capturing parentheses, the
+       data so far is captured. (This feature was added  to  PCRE  at  release
+       8.00.) For example:
+
+         A((?:A|B(*ACCEPT)|C)D)
+
+       This  matches  "AB", "AAD", or "ACD"; when it matches "AB", "B" is cap-
+       tured by the outer parentheses.
+
+         (*FAIL) or (*F)
+
+       This verb causes the match to fail, forcing backtracking to  occur.  It
+       is  equivalent to (?!) but easier to read. The Perl documentation notes
+       that it is probably useful only when combined  with  (?{})  or  (??{}).
+       Those  are,  of course, Perl features that are not present in PCRE. The
+       nearest equivalent is the callout feature, as for example in this  pat-
+       tern:
+
+         a+(?C)(*FAIL)
+
+       A  match  with the string "aaaa" always fails, but the callout is taken
+       before each backtrack happens (in this example, 10 times).
+
+   Verbs that act after backtracking
+
+       The following verbs do nothing when they are encountered. Matching con-
+       tinues  with what follows, but if there is no subsequent match, a fail-
+       ure is forced.  The verbs  differ  in  exactly  what  kind  of  failure
+       occurs.
+
+         (*COMMIT)
+
+       This  verb  causes  the whole match to fail outright if the rest of the
+       pattern does not match. Even if the pattern is unanchored,  no  further
+       attempts  to  find  a match by advancing the starting point take place.
+       Once (*COMMIT) has been passed, pcre_exec() is committed to  finding  a
+       match at the current starting point, or not at all. For example:
+
+         a+(*COMMIT)b
+
+       This  matches  "xxaab" but not "aacaab". It can be thought of as a kind
+       of dynamic anchor, or "I've started, so I must finish."
+
+         (*PRUNE)
+
+       This verb causes the match to fail at the current position if the  rest
+       of the pattern does not match. If the pattern is unanchored, the normal
+       "bumpalong" advance to the next starting character then happens.  Back-
+       tracking  can  occur as usual to the left of (*PRUNE), or when matching
+       to the right of (*PRUNE), but if there is no match to the right,  back-
+       tracking  cannot  cross (*PRUNE).  In simple cases, the use of (*PRUNE)
+       is just an alternative to an atomic group or possessive quantifier, but
+       there  are  some uses of (*PRUNE) that cannot be expressed in any other
+       way.
+
+         (*SKIP)
+
+       This verb is like (*PRUNE), except that if the pattern  is  unanchored,
+       the  "bumpalong" advance is not to the next character, but to the posi-
+       tion in the subject where (*SKIP) was  encountered.  (*SKIP)  signifies
+       that  whatever  text  was  matched leading up to it cannot be part of a
+       successful match. Consider:
+
+         a+(*SKIP)b
+
+       If the subject is "aaaac...",  after  the  first  match  attempt  fails
+       (starting  at  the  first  character in the string), the starting point
+       skips on to start the next attempt at "c". Note that a possessive quan-
+       tifer  does not have the same effect as this example; although it would
+       suppress backtracking  during  the  first  match  attempt,  the  second
+       attempt  would  start at the second character instead of skipping on to
+       "c".
+
+         (*THEN)
+
+       This verb causes a skip to the next alternation if the rest of the pat-
+       tern does not match. That is, it cancels pending backtracking, but only
+       within the current alternation. Its name  comes  from  the  observation
+       that it can be used for a pattern-based if-then-else block:
+
+         ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+
+       If  the COND1 pattern matches, FOO is tried (and possibly further items
+       after the end of the group if FOO succeeds);  on  failure  the  matcher
+       skips  to  the second alternative and tries COND2, without backtracking
+       into COND1. If (*THEN) is used outside  of  any  alternation,  it  acts
+       exactly like (*PRUNE).

+
+PARTIAL MATCHING IN PCRE
+
+       In  normal  use  of  PCRE,  if  the  subject  string  that is passed to
+       pcre_exec() or pcre_dfa_exec() matches as far as it goes,  but  is  too
+       short  to  match  the  entire  pattern, PCRE_ERROR_NOMATCH is returned.
+       There are circumstances where it might be helpful to  distinguish  this
+       case from other cases in which there is no match.
+
+       Consider, for example, an application where a human is required to type
+       in data for a field with specific formatting requirements.  An  example
+       might be a date in the form ddmmmyy, defined by this pattern:
+
+         ^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$
+
+       If the application sees the user's keystrokes one by one, and can check
+       that what has been typed so far is potentially valid,  it  is  able  to
+       raise  an  error  as  soon  as  a  mistake  is made, by beeping and not
+       reflecting the character that has been typed, for example. This immedi-
+       ate  feedback is likely to be a better user interface than a check that
+       is delayed until the entire string has been entered.  Partial  matching
+       can  also  sometimes be useful when the subject string is very long and
+       is not all available at once.
+
+       PCRE supports partial matching by means of  the  PCRE_PARTIAL_SOFT  and
+       PCRE_PARTIAL_HARD options, which can be set when calling pcre_exec() or
+       pcre_dfa_exec(). For backwards compatibility, PCRE_PARTIAL is a synonym
+       for PCRE_PARTIAL_SOFT. The essential difference between the two options
+       is whether or not a partial match is preferred to an  alternative  com-
+       plete  match,  though the details differ between the two matching func-
+       tions. If both options are set, PCRE_PARTIAL_HARD takes precedence.
+
+       Setting a partial matching option disables two of PCRE's optimizations.
+       PCRE  remembers the last literal byte in a pattern, and abandons match-
+       ing immediately if such a byte is not present in  the  subject  string.
+       This  optimization cannot be used for a subject string that might match
+       only partially. If the pattern was  studied,  PCRE  knows  the  minimum
+       length  of  a  matching string, and does not bother to run the matching
+       function on shorter strings. This optimization  is  also  disabled  for
+       partial matching.
+
+
+PARTIAL MATCHING USING pcre_exec()
+
+       A partial match occurs during a call to pcre_exec() whenever the end of
+       the subject string is reached successfully, but  matching  cannot  con-
+       tinue because more characters are needed. However, at least one charac-
+       ter must have been matched. (In other words, a partial match can  never
+       be an empty string.)
+
+       If  PCRE_PARTIAL_SOFT  is  set,  the  partial  match is remembered, but
+       matching continues as normal, and other alternatives in the pattern are
+       tried.   If  no  complete  match  can  be  found,  pcre_exec()  returns
+       PCRE_ERROR_PARTIAL instead of PCRE_ERROR_NOMATCH. If there are at least
+       two slots in the offsets vector, the first of them is set to the offset
+       of the earliest character that was inspected when the partial match was
+       found.  For  convenience,  the  second  offset points to the end of the
+       string so that a substring can easily be identified.
+
+       For the majority of patterns, the first offset identifies the start  of
+       the  partially matched string. However, for patterns that contain look-
+       behind assertions, or \K, or begin with \b or  \B,  earlier  characters
+       have been inspected while carrying out the match. For example:
+
+         /(?<=abc)123/
+
+       This pattern matches "123", but only if it is preceded by "abc". If the
+       subject string is "xyzabc12", the offsets after a partial match are for
+       the  substring  "abc12",  because  all  these  characters are needed if
+       another match is tried with extra characters added.
+
+       If there is more than one partial match, the first one that  was  found
+       provides the data that is returned. Consider this pattern:
+
+         /123\w+X|dogY/
+
+       If  this is matched against the subject string "abc123dog", both alter-
+       natives fail to match, but the end of the  subject  is  reached  during
+       matching,    so    PCRE_ERROR_PARTIAL    is    returned    instead   of
+       PCRE_ERROR_NOMATCH. The  offsets  are  set  to  3  and  9,  identifying
+       "123dog"  as  the first partial match that was found. (In this example,
+       there are two partial matches,  because  "dog"  on  its  own  partially
+       matches the second alternative.)
+
+       If PCRE_PARTIAL_HARD is set for pcre_exec(), it returns PCRE_ERROR_PAR-
+       TIAL as soon as a partial match is found, without continuing to  search
+       for  possible  complete matches. The difference between the two options
+       can be illustrated by a pattern such as:
+
+         /dog(sbody)?/
+
+       This matches either "dog" or "dogsbody", greedily (that is, it  prefers
+       the  longer  string  if  possible). If it is matched against the string
+       "dog" with PCRE_PARTIAL_SOFT, it yields a  complete  match  for  "dog".
+       However, if PCRE_PARTIAL_HARD is set, the result is PCRE_ERROR_PARTIAL.
+       On the other hand, if the pattern is made ungreedy the result  is  dif-
+       ferent:
+
+         /dog(sbody)??/
+
+       In  this case the result is always a complete match because pcre_exec()
+       finds that first, and it never continues  after  finding  a  match.  It
+       might  be easier to follow this explanation by thinking of the two pat-
+       terns like this:
+
+         /dog(sbody)?/    is the same as  /dogsbody|dog/
+         /dog(sbody)??/   is the same as  /dog|dogsbody/
+
+       The second pattern will never  match  "dogsbody"  when  pcre_exec()  is
+       used, because it will always find the shorter match first.
+
+
+PARTIAL MATCHING USING pcre_dfa_exec()
+
+       The  pcre_dfa_exec()  function moves along the subject string character
+       by character, without backtracking, searching for all possible  matches
+       simultaneously.  If the end of the subject is reached before the end of
+       the pattern, there is the possibility of a partial  match,  again  pro-
+       vided that at least one character has matched.
+
+       When  PCRE_PARTIAL_SOFT  is set, PCRE_ERROR_PARTIAL is returned only if
+       there have been no complete matches. Otherwise,  the  complete  matches
+       are  returned.   However,  if PCRE_PARTIAL_HARD is set, a partial match
+       takes precedence over any complete matches. The portion of  the  string
+       that  was  inspected when the longest partial match was found is set as
+       the first matching string, provided there are at least two slots in the
+       offsets vector.
+
+       Because  pcre_dfa_exec()  always searches for all possible matches, and
+       there is no difference between greedy and ungreedy repetition, its  be-
+       haviour is different from pcre_exec when PCRE_PARTIAL_HARD is set. Con-
+       sider the string "dog"  matched  against  the  ungreedy  pattern  shown
+       above:
+
+         /dog(sbody)??/
+
+       Whereas  pcre_exec()  stops  as soon as it finds the complete match for
+       "dog", pcre_dfa_exec() also finds the partial match for "dogsbody", and
+       so returns that when PCRE_PARTIAL_HARD is set.
+
+
+PARTIAL MATCHING AND WORD BOUNDARIES
+
+       If  a  pattern ends with one of sequences \b or \B, which test for word
+       boundaries, partial matching with PCRE_PARTIAL_SOFT can  give  counter-
+       intuitive results. Consider this pattern:
+
+         /\bcat\b/
+
+       This matches "cat", provided there is a word boundary at either end. If
+       the subject string is "the cat", the comparison of the final "t" with a
+       following  character  cannot  take  place, so a partial match is found.
+       However, pcre_exec() carries on with normal matching, which matches  \b
+       at  the  end  of  the subject when the last character is a letter, thus
+       finding a complete match. The result, therefore, is not PCRE_ERROR_PAR-
+       TIAL.  The  same  thing  happens  with pcre_dfa_exec(), because it also
+       finds the complete match.
+
+       Using PCRE_PARTIAL_HARD in this  case  does  yield  PCRE_ERROR_PARTIAL,
+       because then the partial match takes precedence.
+
+
+FORMERLY RESTRICTED PATTERNS
+
+       For releases of PCRE prior to 8.00, because of the way certain internal
+       optimizations  were  implemented  in  the  pcre_exec()  function,   the
+       PCRE_PARTIAL  option  (predecessor  of  PCRE_PARTIAL_SOFT) could not be
+       used with all patterns. From release 8.00 onwards, the restrictions  no
+       longer  apply,  and  partial matching with pcre_exec() can be requested
+       for any pattern.
+
+       Items that were formerly restricted were repeated single characters and
+       repeated  metasequences. If PCRE_PARTIAL was set for a pattern that did
+       not conform to the restrictions, pcre_exec() returned  the  error  code
+       PCRE_ERROR_BADPARTIAL  (-13).  This error code is no longer in use. The
+       PCRE_INFO_OKPARTIAL call to pcre_fullinfo() to find out if  a  compiled
+       pattern can be used for partial matching now always returns 1.
+
+
+EXAMPLE OF PARTIAL MATCHING USING PCRETEST
+
+       If  the  escape  sequence  \P  is  present in a pcretest data line, the
+       PCRE_PARTIAL_SOFT option is used for  the  match.  Here  is  a  run  of
+       pcretest that uses the date example quoted above:
+
+           re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+         data> 25jun04\P
+          0: 25jun04
+          1: jun
+         data> 25dec3\P
+         Partial match: 23dec3
+         data> 3ju\P
+         Partial match: 3ju
+         data> 3juj\P
+         No match
+         data> j\P
+         No match
+
+       The  first  data  string  is  matched completely, so pcretest shows the
+       matched substrings. The remaining four strings do not  match  the  com-
+       plete pattern, but the first two are partial matches. Similar output is
+       obtained when pcre_dfa_exec() is used.
+
+       If the escape sequence \P is present more than once in a pcretest  data
+       line, the PCRE_PARTIAL_HARD option is set for the match.
+
+
+MULTI-SEGMENT MATCHING WITH pcre_dfa_exec()
+
+       When a partial match has been found using pcre_dfa_exec(), it is possi-
+       ble to continue the match by  providing  additional  subject  data  and
+       calling  pcre_dfa_exec()  again  with the same compiled regular expres-
+       sion, this time setting the PCRE_DFA_RESTART option. You must pass  the
+       same working space as before, because this is where details of the pre-
+       vious partial match are stored. Here  is  an  example  using  pcretest,
+       using  the  \R  escape  sequence to set the PCRE_DFA_RESTART option (\D
+       specifies the use of pcre_dfa_exec()):
+
+           re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+         data> 23ja\P\D
+         Partial match: 23ja
+         data> n05\R\D
+          0: n05
+
+       The first call has "23ja" as the subject, and requests  partial  match-
+       ing;  the  second  call  has  "n05"  as  the  subject for the continued
+       (restarted) match.  Notice that when the match is  complete,  only  the
+       last  part  is  shown;  PCRE  does not retain the previously partially-
+       matched string. It is up to the calling program to do that if it  needs
+       to.
+
+       You  can  set  the  PCRE_PARTIAL_SOFT or PCRE_PARTIAL_HARD options with
+       PCRE_DFA_RESTART to continue partial matching over  multiple  segments.
+       This  facility  can  be  used  to  pass  very  long  subject strings to
+       pcre_dfa_exec().
+
+
+MULTI-SEGMENT MATCHING WITH pcre_exec()
+
+       From release 8.00, pcre_exec() can also be  used  to  do  multi-segment
+       matching.  Unlike  pcre_dfa_exec(),  it  is not possible to restart the
+       previous match with a new segment of data. Instead, new  data  must  be
+       added  to  the  previous  subject  string, and the entire match re-run,
+       starting from the point where the partial match occurred. Earlier  data
+       can be discarded.  Consider an unanchored pattern that matches dates:
+
+           re> /\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d/
+         data> The date is 23ja\P
+         Partial match: 23ja
+
+       At  this stage, an application could discard the text preceding "23ja",
+       add on text from the next segment, and call pcre_exec()  again.  Unlike
+       pcre_dfa_exec(),  the  entire matching string must always be available,
+       and the complete matching process occurs for each call, so more  memory
+       and more processing time is needed.
+
+       Note:  If  the pattern contains lookbehind assertions, or \K, or starts
+       with \b or \B, the string that is returned for  a  partial  match  will
+       include  characters  that  precede the partially matched string itself,
+       because these must be retained when adding on  more  characters  for  a
+       subsequent matching attempt.
+
+
+ISSUES WITH MULTI-SEGMENT MATCHING
+
+       Certain types of pattern may give problems with multi-segment matching,
+       whichever matching function is used.
+
+       1. If the pattern contains tests for the beginning or end  of  a  line,
+       you  need  to pass the PCRE_NOTBOL or PCRE_NOTEOL options, as appropri-
+       ate, when the subject string for any call does not contain  the  begin-
+       ning or end of a line.
+
+       2.  Lookbehind  assertions at the start of a pattern are catered for in
+       the offsets that are returned for a partial match. However, in  theory,
+       a  lookbehind assertion later in the pattern could require even earlier
+       characters to be inspected, and it might not have been reached  when  a
+       partial  match occurs. This is probably an extremely unlikely case; you
+       could guard against it to a certain extent by  always  including  extra
+       characters at the start.
+
+       3.  Matching  a subject string that is split into multiple segments may
+       not always produce exactly the same result as matching over one  single
+       long  string,  especially  when  PCRE_PARTIAL_SOFT is used. The section
+       "Partial Matching and Word Boundaries" above describes  an  issue  that
+       arises  if  the  pattern ends with \b or \B. Another kind of difference
+       may occur when there are multiple  matching  possibilities,  because  a
+       partial match result is given only when there are no completed matches.
+       This means that as soon as the shortest match has been found, continua-
+       tion  to  a  new subject segment is no longer possible.  Consider again
+       this pcretest example:
+
+           re> /dog(sbody)?/
+         data> dogsb\P
+          0: dog
+         data> do\P\D
+         Partial match: do
+         data> gsb\R\P\D
+          0: g
+         data> dogsbody\D
+          0: dogsbody
+          1: dog
+
+       The first data line passes the string "dogsb" to  pcre_exec(),  setting
+       the  PCRE_PARTIAL_SOFT  option.  Although the string is a partial match
+       for "dogsbody", the  result  is  not  PCRE_ERROR_PARTIAL,  because  the
+       shorter  string  "dog" is a complete match. Similarly, when the subject
+       is presented to pcre_dfa_exec() in several parts ("do" and "gsb"  being
+       the first two) the match stops when "dog" has been found, and it is not
+       possible to continue. On the other hand, if "dogsbody" is presented  as
+       a single string, pcre_dfa_exec() finds both matches.
+
+       Because of these problems, it is probably best to use PCRE_PARTIAL_HARD
+       when matching multi-segment data. The example above then  behaves  dif-
+       ferently:
+
+           re> /dog(sbody)?/
+         data> dogsb\P\P
+         Partial match: dogsb
+         data> do\P\D
+         Partial match: do
+         data> gsb\R\P\P\D
+         Partial match: gsb
+
+
+       4. Patterns that contain alternatives at the top level which do not all
+       start with the  same  pattern  item  may  not  work  as  expected  when
+       PCRE_DFA_RESTART  is  used  with pcre_dfa_exec(). For example, consider
+       this pattern:
+
+         1234|3789
+
+       If the first part of the subject is "ABC123", a partial  match  of  the
+       first  alternative  is found at offset 3. There is no partial match for
+       the second alternative, because such a match does not start at the same
+       point  in  the  subject  string. Attempting to continue with the string
+       "7890" does not yield a match  because  only  those  alternatives  that
+       match  at  one  point in the subject are remembered. The problem arises
+       because the start of the second alternative matches  within  the  first
+       alternative.  There  is  no  problem with anchored patterns or patterns
+       such as:
+
+         1234|ABCD
+
+       where no string can be a partial match for both alternatives.  This  is
+       not  a  problem if pcre_exec() is used, because the entire match has to
+       be rerun each time:
+
+           re> /1234|3789/
+         data> ABC123\P
+         Partial match: 123
+         data> 1237890
+          0: 3789
+
+       Of course, instead of using PCRE_DFA_PARTIAL, the same technique of re-
+       running the entire match can also be used with pcre_dfa_exec(). Another
+       possibility is to work with two buffers. If a partial match at offset n
+       in  the first buffer is followed by "no match" when PCRE_DFA_RESTART is
+       used on the second buffer, you can then try a  new  match  starting  at
+       offset n+1 in the first buffer.

+
+SAVING AND RE-USING PRECOMPILED PCRE PATTERNS
+
+       If  you  are running an application that uses a large number of regular
+       expression patterns, it may be useful to store them  in  a  precompiled
+       form  instead  of  having to compile them every time the application is
+       run.  If you are not  using  any  private  character  tables  (see  the
+       pcre_maketables()  documentation),  this is relatively straightforward.
+       If you are using private tables, it is a little bit more complicated.
+
+       If you save compiled patterns to a file, you can copy them to a differ-
+       ent  host  and  run them there. This works even if the new host has the
+       opposite endianness to the one on which  the  patterns  were  compiled.
+       There  may  be a small performance penalty, but it should be insignifi-
+       cant. However, compiling regular expressions with one version  of  PCRE
+       for  use  with  a  different  version is not guaranteed to work and may
+       cause crashes.
+
+
+SAVING A COMPILED PATTERN
+       The value returned by pcre_compile() points to a single block of memory
+       that  holds  the compiled pattern and associated data. You can find the
+       length of this block in bytes by calling pcre_fullinfo() with an  argu-
+       ment  of  PCRE_INFO_SIZE. You can then save the data in any appropriate
+       manner. Here is sample code that compiles a pattern and writes it to  a
+       file. It assumes that the variable fd refers to a file that is open for
+       output:
+
+         int erroroffset, rc, size;
+         char *error;
+         pcre *re;
+
+         re = pcre_compile("my pattern", 0, &error, &erroroffset, NULL);
+         if (re == NULL) { ... handle errors ... }
+         rc = pcre_fullinfo(re, NULL, PCRE_INFO_SIZE, &size);
+         if (rc < 0) { ... handle errors ... }
+         rc = fwrite(re, 1, size, fd);
+         if (rc != size) { ... handle errors ... }
+
+       In this example, the bytes  that  comprise  the  compiled  pattern  are
+       copied  exactly.  Note that this is binary data that may contain any of
+       the 256 possible byte  values.  On  systems  that  make  a  distinction
+       between binary and non-binary data, be sure that the file is opened for
+       binary output.
+
+       If you want to write more than one pattern to a file, you will have  to
+       devise  a  way of separating them. For binary data, preceding each pat-
+       tern with its length is probably  the  most  straightforward  approach.
+       Another  possibility is to write out the data in hexadecimal instead of
+       binary, one pattern to a line.
+
+       Saving compiled patterns in a file is only one possible way of  storing
+       them  for later use. They could equally well be saved in a database, or
+       in the memory of some daemon process that passes them  via  sockets  to
+       the processes that want them.
+
+       If  the pattern has been studied, it is also possible to save the study
+       data in a similar way to the compiled  pattern  itself.  When  studying
+       generates  additional  information, pcre_study() returns a pointer to a
+       pcre_extra data block. Its format is defined in the section on matching
+       a  pattern in the pcreapi documentation. The study_data field points to
+       the binary study data,  and  this  is  what  you  must  save  (not  the
+       pcre_extra  block itself). The length of the study data can be obtained
+       by calling pcre_fullinfo() with  an  argument  of  PCRE_INFO_STUDYSIZE.
+       Remember  to check that pcre_study() did return a non-NULL value before
+       trying to save the study data.
+
+
+RE-USING A PRECOMPILED PATTERN
+
+       Re-using a precompiled pattern is straightforward. Having  reloaded  it
+       into   main   memory,   you   pass   its   pointer  to  pcre_exec()  or
+       pcre_dfa_exec() in the usual way. This  should  work  even  on  another
+       host,  and  even  if  that  host has the opposite endianness to the one
+       where the pattern was compiled.
+
+       However, if you passed a pointer to custom character  tables  when  the
+       pattern  was  compiled  (the  tableptr argument of pcre_compile()), you
+       must now pass a similar  pointer  to  pcre_exec()  or  pcre_dfa_exec(),
+       because  the  value  saved  with the compiled pattern will obviously be
+       nonsense. A field in a pcre_extra() block is used to pass this data, as
+       described  in the section on matching a pattern in the pcreapi documen-
+       tation.
+
+       If you did not provide custom character tables  when  the  pattern  was
+       compiled,  the  pointer  in  the compiled pattern is NULL, which causes
+       pcre_exec() to use PCRE's internal tables. Thus, you  do  not  need  to
+       take any special action at run time in this case.
+
+       If  you  saved study data with the compiled pattern, you need to create
+       your own pcre_extra data block and set the study_data field to point to
+       the  reloaded  study  data. You must also set the PCRE_EXTRA_STUDY_DATA
+       bit in the flags field to indicate that study  data  is  present.  Then
+       pass  the  pcre_extra  block  to  pcre_exec() or pcre_dfa_exec() in the
+       usual way.
+
+
+COMPATIBILITY WITH DIFFERENT PCRE RELEASES
+
+       In general, it is safest to  recompile  all  saved  patterns  when  you
+       update  to  a new PCRE release, though not all updates actually require
+       this. Recompiling is definitely needed for release 7.2.

+PCREPERFORM(3)                                                  PCREPERFORM(3)

+NAME
+       PCRE - Perl-compatible regular expressions
+
+
+PCRE PERFORMANCE
+
+       Two  aspects  of performance are discussed below: memory usage and pro-
+       cessing time. The way you express your pattern as a regular  expression
+       can affect both of them.
+
+
+MEMORY USAGE
+
+       Patterns are compiled by PCRE into a reasonably efficient byte code, so
+       that most simple patterns do not use much memory. However, there is one
+       case where memory usage can be unexpectedly large. When a parenthesized
+       subpattern has a quantifier with a minimum greater than 1 and/or a lim-
+       ited  maximum,  the  whole subpattern is repeated in the compiled code.
+       For example, the pattern
+
+         (abc|def){2,4}
+
+       is compiled as if it were
+
+         (abc|def)(abc|def)((abc|def)(abc|def)?)?
+
+       (Technical aside: It is done this way so that backtrack  points  within
+       each of the repetitions can be independently maintained.)
+
+       For  regular expressions whose quantifiers use only small numbers, this
+       is not usually a problem. However, if the numbers are large,  and  par-
+       ticularly  if  such repetitions are nested, the memory usage can become
+       an embarrassment. For example, the very simple pattern
+
+         ((ab){1,1000}c){1,3}
+
+       uses 51K bytes when compiled. When PCRE is compiled  with  its  default
+       internal  pointer  size of two bytes, the size limit on a compiled pat-
+       tern is 64K, and this is reached with the above pattern  if  the  outer
+       repetition is increased from 3 to 4. PCRE can be compiled to use larger
+       internal pointers and thus handle larger compiled patterns, but  it  is
+       better to try to rewrite your pattern to use less memory if you can.
+
+       One  way  of reducing the memory usage for such patterns is to make use
+       of PCRE's "subroutine" facility. Re-writing the above pattern as
+
+         ((ab)(?2){0,999}c)(?1){0,2}
+
+       reduces the memory requirements to 18K, and indeed it remains under 20K
+       even  with the outer repetition increased to 100. However, this pattern
+       is not exactly equivalent, because the "subroutine" calls  are  treated
+       as  atomic groups into which there can be no backtracking if there is a
+       subsequent matching failure. Therefore, PCRE cannot  do  this  kind  of
+       rewriting  automatically.   Furthermore,  there is a noticeable loss of
+       speed when executing the modified pattern. Nevertheless, if the  atomic
+       grouping  is  not  a  problem and the loss of speed is acceptable, this
+       kind of rewriting will allow you to process patterns that  PCRE  cannot
+       otherwise handle.
+
+
+PROCESSING TIME
+
+       Certain  items  in regular expression patterns are processed more effi-
+       ciently than others. It is more efficient to use a character class like
+       [aeiou]   than   a   set   of  single-character  alternatives  such  as
+       (a|e|i|o|u). In general, the simplest construction  that  provides  the
+       required behaviour is usually the most efficient. Jeffrey Friedl's book
+       contains a lot of useful general discussion  about  optimizing  regular
+       expressions  for  efficient  performance.  This document contains a few
+       observations about PCRE.
+
+       Using Unicode character properties (the \p,  \P,  and  \X  escapes)  is
+       slow,  because PCRE has to scan a structure that contains data for over
+       fifteen thousand characters whenever it needs a  character's  property.
+       If  you  can  find  an  alternative pattern that does not use character
+       properties, it will probably be faster.
+
+       When a pattern begins with .* not in  parentheses,  or  in  parentheses
+       that are not the subject of a backreference, and the PCRE_DOTALL option
+       is set, the pattern is implicitly anchored by PCRE, since it can  match
+       only  at  the start of a subject string. However, if PCRE_DOTALL is not
+       set, PCRE cannot make this optimization, because  the  .  metacharacter
+       does  not then match a newline, and if the subject string contains new-
+       lines, the pattern may match from the character  immediately  following
+       one of them instead of from the very start. For example, the pattern
+
+         .*second
+
+       matches  the subject "first\nand second" (where \n stands for a newline
+       character), with the match starting at the seventh character. In  order
+       to do this, PCRE has to retry the match starting after every newline in
+       the subject.
+
+       If you are using such a pattern with subject strings that do  not  con-
+       tain newlines, the best performance is obtained by setting PCRE_DOTALL,
+       or starting the pattern with ^.* or ^.*? to indicate  explicit  anchor-
+       ing.  That saves PCRE from having to scan along the subject looking for
+       a newline to restart at.
+
+       Beware of patterns that contain nested indefinite  repeats.  These  can
+       take  a  long time to run when applied to a string that does not match.
+       Consider the pattern fragment
+
+         ^(a+)*
+
+       This can match "aaaa" in 16 different ways, and this  number  increases
+       very  rapidly  as the string gets longer. (The * repeat can match 0, 1,
+       2, 3, or 4 times, and for each of those cases other than 0 or 4, the  +
+       repeats  can  match  different numbers of times.) When the remainder of
+       the pattern is such that the entire match is going to fail, PCRE has in
+       principle  to  try  every  possible  variation,  and  this  can take an
+       extremely long time, even for relatively short strings.
+
+       An optimization catches some of the more simple cases such as
+
+         (a+)*b
+
+       where a literal character follows. Before  embarking  on  the  standard
+       matching  procedure,  PCRE checks that there is a "b" later in the sub-
+       ject string, and if there is not, it fails the match immediately.  How-
+       ever,  when  there  is no following literal this optimization cannot be
+       used. You can see the difference by comparing the behaviour of
+
+         (a+)*\d
+
+       with the pattern above. The former gives  a  failure  almost  instantly
+       when  applied  to  a  whole  line of "a" characters, whereas the latter
+       takes an appreciable time with strings longer than about 20 characters.
+
+       In many cases, the solution to this kind of performance issue is to use
+       an atomic group or a possessive quantifier.

+DESCRIPTION
+
+       This  set  of  functions provides a POSIX-style API to the PCRE regular
+       expression package. See the pcreapi documentation for a description  of
+       PCRE's native API, which contains much additional functionality.
+
+       The functions described here are just wrapper functions that ultimately
+       call  the  PCRE  native  API.  Their  prototypes  are  defined  in  the
+       pcreposix.h  header  file,  and  on  Unix systems the library itself is
+       called pcreposix.a, so can be accessed by  adding  -lpcreposix  to  the
+       command  for  linking  an application that uses them. Because the POSIX
+       functions call the native ones, it is also necessary to add -lpcre.
+
+       I have implemented only those POSIX option bits that can be  reasonably
+       mapped  to PCRE native options. In addition, the option REG_EXTENDED is
+       defined with the value zero. This has no  effect,  but  since  programs
+       that  are  written  to  the POSIX interface often use it, this makes it
+       easier to slot in PCRE as a replacement library.  Other  POSIX  options
+       are not even defined.
+
+       There  are also some other options that are not defined by POSIX. These
+       have been added at the request of users who want to make use of certain
+       PCRE-specific features via the POSIX calling interface.
+
+       When  PCRE  is  called  via these functions, it is only the API that is
+       POSIX-like in style. The syntax and semantics of  the  regular  expres-
+       sions  themselves  are  still  those of Perl, subject to the setting of
+       various PCRE options, as described below. "POSIX-like in  style"  means
+       that  the  API  approximates  to  the POSIX definition; it is not fully
+       POSIX-compatible, and in multi-byte encoding  domains  it  is  probably
+       even less compatible.
+
+       The  header for these functions is supplied as pcreposix.h to avoid any
+       potential clash with other POSIX  libraries.  It  can,  of  course,  be
+       renamed or aliased as regex.h, which is the "correct" name. It provides
+       two structure types, regex_t for  compiled  internal  forms,  and  reg-
+       match_t  for  returning  captured substrings. It also defines some con-
+       stants whose names start  with  "REG_";  these  are  used  for  setting
+       options and identifying error codes.
+
+
+COMPILING A PATTERN
+
+       The  function regcomp() is called to compile a pattern into an internal
+       form. The pattern is a C string terminated by a  binary  zero,  and  is
+       passed  in  the  argument  pattern. The preg argument is a pointer to a
+       regex_t structure that is used as a base for storing information  about
+       the compiled regular expression.
+
+       The argument cflags is either zero, or contains one or more of the bits
+       defined by the following macros:
+
+         REG_DOTALL
+
+       The PCRE_DOTALL option is set when the regular expression is passed for
+       compilation to the native function. Note that REG_DOTALL is not part of
+       the POSIX standard.
+
+         REG_ICASE
+
+       The PCRE_CASELESS option is set when the regular expression  is  passed
+       for compilation to the native function.
+
+         REG_NEWLINE
+
+       The  PCRE_MULTILINE option is set when the regular expression is passed
+       for compilation to the native function. Note that this does  not  mimic
+       the  defined  POSIX  behaviour  for REG_NEWLINE (see the following sec-
+       tion).
+
+         REG_NOSUB
+
+       The PCRE_NO_AUTO_CAPTURE option is set when the regular  expression  is
+       passed for compilation to the native function. In addition, when a pat-
+       tern that is compiled with this flag is passed to regexec() for  match-
+       ing,  the  nmatch  and  pmatch  arguments  are ignored, and no captured
+       strings are returned.
+
+         REG_UNGREEDY
+
+       The PCRE_UNGREEDY option is set when the regular expression  is  passed
+       for  compilation  to the native function. Note that REG_UNGREEDY is not
+       part of the POSIX standard.
+
+         REG_UTF8
+
+       The PCRE_UTF8 option is set when the regular expression is  passed  for
+       compilation  to the native function. This causes the pattern itself and
+       all data strings used for matching it to be treated as  UTF-8  strings.
+       Note that REG_UTF8 is not part of the POSIX standard.
+
+       In  the  absence  of  these  flags, no options are passed to the native
+       function.  This means the the  regex  is  compiled  with  PCRE  default
+       semantics.  In particular, the way it handles newline characters in the
+       subject string is the Perl way, not the POSIX way.  Note  that  setting
+       PCRE_MULTILINE  has only some of the effects specified for REG_NEWLINE.
+       It does not affect the way newlines are matched by . (they are not)  or
+       by a negative class such as [^a] (they are).
+
+       The  yield of regcomp() is zero on success, and non-zero otherwise. The
+       preg structure is filled in on success, and one member of the structure
+       is  public: re_nsub contains the number of capturing subpatterns in the
+       regular expression. Various error codes are defined in the header file.
+
+       NOTE: If the yield of regcomp() is non-zero, you must  not  attempt  to
+       use the contents of the preg structure. If, for example, you pass it to
+       regexec(), the result is undefined and your program is likely to crash.
+
+
+MATCHING NEWLINE CHARACTERS
+
+       This area is not simple, because POSIX and Perl take different views of
+       things.   It  is  not possible to get PCRE to obey POSIX semantics, but
+       then PCRE was never intended to be a POSIX engine. The following  table
+       lists  the  different  possibilities for matching newline characters in
+       PCRE:
+
+                                 Default   Change with
+
+         . matches newline          no     PCRE_DOTALL
+         newline matches [^a]       yes    not changeable
+         $ matches \n at end        yes    PCRE_DOLLARENDONLY
+         $ matches \n in middle     no     PCRE_MULTILINE
+         ^ matches \n in middle     no     PCRE_MULTILINE
+
+       This is the equivalent table for POSIX:
+
+                                 Default   Change with
+
+         . matches newline          yes    REG_NEWLINE
+         newline matches [^a]       yes    REG_NEWLINE
+         $ matches \n at end        no     REG_NEWLINE
+         $ matches \n in middle     no     REG_NEWLINE
+         ^ matches \n in middle     no     REG_NEWLINE
+
+       PCRE's behaviour is the same as Perl's, except that there is no equiva-
+       lent  for  PCRE_DOLLAR_ENDONLY in Perl. In both PCRE and Perl, there is
+       no way to stop newline from matching [^a].
+
+       The  default  POSIX  newline  handling  can  be  obtained  by   setting
+       PCRE_DOTALL  and  PCRE_DOLLAR_ENDONLY, but there is no way to make PCRE
+       behave exactly as for the REG_NEWLINE action.
+
+
+MATCHING A PATTERN
+
+       The function regexec() is called  to  match  a  compiled  pattern  preg
+       against  a  given string, which is by default terminated by a zero byte
+       (but see REG_STARTEND below), subject to the options in  eflags.  These
+       can be:
+
+         REG_NOTBOL
+
+       The PCRE_NOTBOL option is set when calling the underlying PCRE matching
+       function.
+
+         REG_NOTEMPTY
+
+       The PCRE_NOTEMPTY option is set when calling the underlying PCRE match-
+       ing function. Note that REG_NOTEMPTY is not part of the POSIX standard.
+       However, setting this option can give more POSIX-like behaviour in some
+       situations.
+
+         REG_NOTEOL
+
+       The PCRE_NOTEOL option is set when calling the underlying PCRE matching
+       function.
+
+         REG_STARTEND
+
+       The string is considered to start at string +  pmatch[0].rm_so  and  to
+       have  a terminating NUL located at string + pmatch[0].rm_eo (there need
+       not actually be a NUL at that location), regardless  of  the  value  of
+       nmatch.  This  is a BSD extension, compatible with but not specified by
+       IEEE Standard 1003.2 (POSIX.2), and should  be  used  with  caution  in
+       software intended to be portable to other systems. Note that a non-zero
+       rm_so does not imply REG_NOTBOL; REG_STARTEND affects only the location
+       of the string, not how it is matched.
+
+       If  the pattern was compiled with the REG_NOSUB flag, no data about any
+       matched strings  is  returned.  The  nmatch  and  pmatch  arguments  of
+       regexec() are ignored.
+
+       If the value of nmatch is zero, or if the value pmatch is NULL, no data
+       about any matched strings is returned.
+
+       Otherwise,the portion of the string that was matched, and also any cap-
+       tured substrings, are returned via the pmatch argument, which points to
+       an array of nmatch structures of type regmatch_t, containing  the  mem-
+       bers  rm_so  and rm_eo. These contain the offset to the first character
+       of each substring and the offset to the first character after  the  end
+       of  each substring, respectively. The 0th element of the vector relates
+       to the entire portion of string that was matched;  subsequent  elements
+       relate  to  the capturing subpatterns of the regular expression. Unused
+       entries in the array have both structure members set to -1.
+
+       A successful match yields  a  zero  return;  various  error  codes  are
+       defined  in  the  header  file,  of which REG_NOMATCH is the "expected"
+       failure code.
+
+
+ERROR MESSAGES
+
+       The regerror() function maps a non-zero errorcode from either regcomp()
+       or  regexec()  to  a  printable message. If preg is not NULL, the error
+       should have arisen from the use of that structure. A message terminated
+       by  a  binary  zero  is  placed  in  errbuf. The length of the message,
+       including the zero, is limited to errbuf_size. The yield of  the  func-
+       tion is the size of buffer needed to hold the whole message.
+
+
+MEMORY USAGE
+
+       Compiling  a regular expression causes memory to be allocated and asso-
+       ciated with the preg structure. The function regfree() frees  all  such
+       memory,  after  which  preg may no longer be used as a compiled expres-
+       sion.

+
+
+DESCRIPTION
+
+       The  C++  wrapper  for PCRE was provided by Google Inc. Some additional
+       functionality was added by Giuseppe Maxia. This brief man page was con-
+       structed  from  the  notes  in the pcrecpp.h file, which should be con-
+       sulted for further details.
+
+
+MATCHING INTERFACE
+
+       The "FullMatch" operation checks that supplied text matches a  supplied
+       pattern  exactly.  If pointer arguments are supplied, it copies matched
+       sub-strings that match sub-patterns into them.
+
+         Example: successful match
+            pcrecpp::RE re("h.*o");
+            re.FullMatch("hello");
+
+         Example: unsuccessful match (requires full match):
+            pcrecpp::RE re("e");
+            !re.FullMatch("hello");
+
+         Example: creating a temporary RE object:
+            pcrecpp::RE("h.*o").FullMatch("hello");
+
+       You can pass in a "const char*" or a "string" for "text". The  examples
+       below  tend to use a const char*. You can, as in the different examples
+       above, store the RE object explicitly in a variable or use a  temporary
+       RE  object.  The  examples below use one mode or the other arbitrarily.
+       Either could correctly be used for any of these examples.
+
+       You must supply extra pointer arguments to extract matched subpieces.
+
+         Example: extracts "ruby" into "s" and 1234 into "i"
+            int i;
+            string s;
+            pcrecpp::RE re("(\\w+):(\\d+)");
+            re.FullMatch("ruby:1234", &s, &i);
+
+         Example: does not try to extract any extra sub-patterns
+            re.FullMatch("ruby:1234", &s);
+
+         Example: does not try to extract into NULL
+            re.FullMatch("ruby:1234", NULL, &i);
+
+         Example: integer overflow causes failure
+            !re.FullMatch("ruby:1234567891234", NULL, &i);
+
+         Example: fails because there aren't enough sub-patterns:
+            !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s);
+
+         Example: fails because string cannot be stored in integer
+            !pcrecpp::RE("(.*)").FullMatch("ruby", &i);
+
+       The provided pointer arguments can be pointers to  any  scalar  numeric
+       type, or one of:
+
+          string        (matched piece is copied to string)
+          StringPiece   (StringPiece is mutated to point to matched piece)
+          T             (where "bool T::ParseFrom(const char*, int)" exists)
+          NULL          (the corresponding matched sub-pattern is not copied)
+
+       The  function returns true iff all of the following conditions are sat-
+       isfied:
+
+         a. "text" matches "pattern" exactly;
+
+         b. The number of matched sub-patterns is >= number of supplied
+            pointers;
+
+         c. The "i"th argument has a suitable type for holding the
+            string captured as the "i"th sub-pattern. If you pass in
+            void * NULL for the "i"th argument, or a non-void * NULL
+            of the correct type, or pass fewer arguments than the
+            number of sub-patterns, "i"th captured sub-pattern is
+            ignored.
+
+       CAVEAT: An optional sub-pattern that does  not  exist  in  the  matched
+       string  is  assigned  the  empty  string. Therefore, the following will
+       return false (because the empty string is not a valid number):
+
+          int number;
+          pcrecpp::RE::FullMatch("abc", "[a-z]+(\\d+)?", &number);
+
+       The matching interface supports at most 16 arguments per call.  If  you
+       need    more,    consider    using    the    more   general   interface
+       pcrecpp::RE::DoMatch. See pcrecpp.h for the signature for DoMatch.
+
+       NOTE: Do not use no_arg, which is used internally to mark the end of  a
+       list  of optional arguments, as a placeholder for missing arguments, as
+       this can lead to segfaults.
+
+
+QUOTING METACHARACTERS
+
+       You can use the "QuoteMeta" operation to insert backslashes before  all
+       potentially  meaningful  characters  in  a string. The returned string,
+       used as a regular expression, will exactly match the original string.
+
+         Example:
+            string quoted = RE::QuoteMeta(unquoted);
+
+       Note that it's legal to escape a character even if it  has  no  special
+       meaning  in  a  regular expression -- so this function does that. (This
+       also makes it identical to the perl function  of  the  same  name;  see
+       "perldoc    -f    quotemeta".)    For   example,   "1.5-2.0?"   becomes
+       "1\.5\-2\.0\?".
+
+
+PARTIAL MATCHES
+
+       You can use the "PartialMatch" operation when you want the  pattern  to
+       match any substring of the text.
+
+         Example: simple search for a string:
+            pcrecpp::RE("ell").PartialMatch("hello");
+
+         Example: find first number in a string:
+            int number;
+            pcrecpp::RE re("(\\d+)");
+            re.PartialMatch("x*100 + 20", &number);
+            assert(number == 100);
+
+
+UTF-8 AND THE MATCHING INTERFACE
+
+       By  default,  pattern  and text are plain text, one byte per character.
+       The UTF8 flag, passed to  the  constructor,  causes  both  pattern  and
+       string to be treated as UTF-8 text, still a byte stream but potentially
+       multiple bytes per character. In practice, the text is likelier  to  be
+       UTF-8  than  the pattern, but the match returned may depend on the UTF8
+       flag, so always use it when matching UTF8 text. For example,  "."  will
+       match  one  byte normally but with UTF8 set may match up to three bytes
+       of a multi-byte character.
+
+         Example:
+            pcrecpp::RE_Options options;
+            options.set_utf8();
+            pcrecpp::RE re(utf8_pattern, options);
+            re.FullMatch(utf8_string);
+
+         Example: using the convenience function UTF8():
+            pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8());
+            re.FullMatch(utf8_string);
+
+       NOTE: The UTF8 flag is ignored if pcre was not configured with the
+             --enable-utf8 flag.
+
+
+PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE
+
+       PCRE defines some modifiers to  change  the  behavior  of  the  regular
+       expression   engine.  The  C++  wrapper  defines  an  auxiliary  class,
+       RE_Options, as a vehicle to pass such modifiers to  a  RE  class.  Cur-
+       rently, the following modifiers are supported:
+
+          modifier              description               Perl corresponding
+
+          PCRE_CASELESS         case insensitive match      /i
+          PCRE_MULTILINE        multiple lines match        /m
+          PCRE_DOTALL           dot matches newlines        /s
+          PCRE_DOLLAR_ENDONLY   $ matches only at end       N/A
+          PCRE_EXTRA            strict escape parsing       N/A
+          PCRE_EXTENDED         ignore whitespaces          /x
+          PCRE_UTF8             handles UTF8 chars          built-in
+          PCRE_UNGREEDY         reverses * and *?           N/A
+          PCRE_NO_AUTO_CAPTURE  disables capturing parens   N/A (*)
+
+       (*)  Both Perl and PCRE allow non capturing parentheses by means of the
+       "?:" modifier within the pattern itself. e.g. (?:ab|cd) does  not  cap-
+       ture, while (ab|cd) does.
+
+       For  a  full  account on how each modifier works, please check the PCRE
+       API reference page.
+
+       For each modifier, there are two member functions whose  name  is  made
+       out  of  the  modifier  in  lowercase,  without the "PCRE_" prefix. For
+       instance, PCRE_CASELESS is handled by
+
+         bool caseless()
+
+       which returns true if the modifier is set, and
+
+         RE_Options & set_caseless(bool)
+
+       which sets or unsets the modifier. Moreover, PCRE_EXTRA_MATCH_LIMIT can
+       be  accessed  through  the  set_match_limit()  and match_limit() member
+       functions. Setting match_limit to a non-zero value will limit the  exe-
+       cution  of pcre to keep it from doing bad things like blowing the stack
+       or taking an eternity to return a result.  A  value  of  5000  is  good
+       enough  to stop stack blowup in a 2MB thread stack. Setting match_limit
+       to  zero  disables  match  limiting.  Alternatively,   you   can   call
+       match_limit_recursion()  which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to
+       limit how much  PCRE  recurses.  match_limit()  limits  the  number  of
+       matches PCRE does; match_limit_recursion() limits the depth of internal
+       recursion, and therefore the amount of stack that is used.
+
+       Normally, to pass one or more modifiers to a RE class,  you  declare  a
+       RE_Options object, set the appropriate options, and pass this object to
+       a RE constructor. Example:
+
+          RE_options opt;
+          opt.set_caseless(true);
+          if (RE("HELLO", opt).PartialMatch("hello world")) ...
+
+       RE_options has two constructors. The default constructor takes no argu-
+       ments  and creates a set of flags that are off by default. The optional
+       parameter option_flags is to facilitate transfer of legacy code from  C
+       programs.  This lets you do
+
+          RE(pattern,
+            RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str);
+
+       However, new code is better off doing
+
+          RE(pattern,
+            RE_Options().set_caseless(true).set_multiline(true))
+              .PartialMatch(str);
+
+       If you are going to pass one of the most used modifiers, there are some
+       convenience functions that return a RE_Options class with the appropri-
+       ate  modifier  already  set: CASELESS(), UTF8(), MULTILINE(), DOTALL(),
+       and EXTENDED().
+
+       If you need to set several options at once, and you don't  want  to  go
+       through  the pains of declaring a RE_Options object and setting several
+       options, there is a parallel method that give you such ability  on  the
+       fly.  You  can  concatenate several set_xxxxx() member functions, since
+       each of them returns a reference to its class object. For  example,  to
+       pass  PCRE_CASELESS, PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one
+       statement, you may write:
+
+          RE(" ^ xyz \\s+ .* blah$",
+            RE_Options()
+              .set_caseless(true)
+              .set_extended(true)
+              .set_multiline(true)).PartialMatch(sometext);
+
+
+SCANNING TEXT INCREMENTALLY
+
+       The "Consume" operation may be useful if you want to  repeatedly  match
+       regular expressions at the front of a string and skip over them as they
+       match. This requires use of the "StringPiece" type, which represents  a
+       sub-range  of  a  real  string.  Like RE, StringPiece is defined in the
+       pcrecpp namespace.
+
+         Example: read lines of the form "var = value" from a string.
+            string contents = ...;                 // Fill string somehow
+            pcrecpp::StringPiece input(contents);  // Wrap in a StringPiece
+
+            string var;
+            int value;
+            pcrecpp::RE re("(\\w+) = (\\d+)\n");
+            while (re.Consume(&input, &var, &value)) {
+              ...;
+            }
+
+       Each successful call  to  "Consume"  will  set  "var/value",  and  also
+       advance "input" so it points past the matched text.
+
+       The  "FindAndConsume"  operation  is  similar to "Consume" but does not
+       anchor your match at the beginning of  the  string.  For  example,  you
+       could extract all words from a string by repeatedly calling
+
+         pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word)
+
+
+PARSING HEX/OCTAL/C-RADIX NUMBERS
+
+       By default, if you pass a pointer to a numeric value, the corresponding
+       text is interpreted as a base-10  number.  You  can  instead  wrap  the
+       pointer with a call to one of the operators Hex(), Octal(), or CRadix()
+       to interpret the text in another base. The CRadix  operator  interprets
+       C-style  "0"  (base-8)  and  "0x"  (base-16)  prefixes, but defaults to
+       base-10.
+
+         Example:
+           int a, b, c, d;
+           pcrecpp::RE re("(.*) (.*) (.*) (.*)");
+           re.FullMatch("100 40 0100 0x40",
+                        pcrecpp::Octal(&a), pcrecpp::Hex(&b),
+                        pcrecpp::CRadix(&c), pcrecpp::CRadix(&d));
+
+       will leave 64 in a, b, c, and d.
+
+
+REPLACING PARTS OF STRINGS
+
+       You can replace the first match of "pattern" in "str"  with  "rewrite".
+       Within  "rewrite",  backslash-escaped  digits (\1 to \9) can be used to
+       insert text matching corresponding parenthesized group  from  the  pat-
+       tern. \0 in "rewrite" refers to the entire matching text. For example:
+
+         string s = "yabba dabba doo";
+         pcrecpp::RE("b+").Replace("d", &s);
+
+       will  leave  "s" containing "yada dabba doo". The result is true if the
+       pattern matches and a replacement occurs, false otherwise.
+
+       GlobalReplace is like Replace except that it replaces  all  occurrences
+       of  the  pattern  in  the string with the rewrite. Replacements are not
+       subject to re-matching. For example:
+
+         string s = "yabba dabba doo";
+         pcrecpp::RE("b+").GlobalReplace("d", &s);
+
+       will leave "s" containing "yada dada doo". It  returns  the  number  of
+       replacements made.
+
+       Extract  is like Replace, except that if the pattern matches, "rewrite"
+       is copied into "out" (an additional argument) with substitutions.   The
+       non-matching  portions  of "text" are ignored. Returns true iff a match
+       occurred and the extraction happened successfully;  if no match occurs,
+       the string is left unaffected.

+
+PCRE SAMPLE PROGRAM
+
+       A simple, complete demonstration program, to get you started with using
+       PCRE, is supplied in the file pcredemo.c in the  PCRE  distribution.  A
+       listing  of this program is given in the pcredemo documentation. If you
+       do not have a copy of the PCRE distribution, you can save this  listing
+       to re-create pcredemo.c.
+
+       The program compiles the regular expression that is its first argument,
+       and matches it against the subject string in its  second  argument.  No
+       PCRE  options are set, and default character tables are used. If match-
+       ing succeeds, the program outputs  the  portion  of  the  subject  that
+       matched, together with the contents of any captured substrings.
+
+       If the -g option is given on the command line, the program then goes on
+       to check for further matches of the same regular expression in the same
+       subject  string. The logic is a little bit tricky because of the possi-
+       bility of matching an empty string. Comments in the code  explain  what
+       is going on.
+
+       If  PCRE  is  installed in the standard include and library directories
+       for your operating system, you should be able to compile the demonstra-
+       tion program using this command:
+
+         gcc -o pcredemo pcredemo.c -lpcre
+
+       If  PCRE is installed elsewhere, you may need to add additional options
+       to the command line. For example, on a Unix-like system that  has  PCRE
+       installed  in  /usr/local,  you  can  compile the demonstration program
+       using a command like this:
+
+         gcc -o pcredemo -I/usr/local/include pcredemo.c \
+             -L/usr/local/lib -lpcre
+
+       Once you have compiled the demonstration program, you  can  run  simple
+       tests like this:
+
+         ./pcredemo 'cat|dog' 'the cat sat on the mat'
+         ./pcredemo -g 'cat|dog' 'the dog sat on the cat'
+
+       Note  that  there  is  a  much  more comprehensive test program, called
+       pcretest, which supports  many  more  facilities  for  testing  regular
+       expressions and the PCRE library. The pcredemo program is provided as a
+       simple coding example.
+
+       When you try to run pcredemo when PCRE is not installed in the standard
+       library  directory,  you  may  get an error like this on some operating
+       systems (e.g. Solaris):
+
+         ld.so.1: a.out: fatal: libpcre.so.0: open failed:  No  such  file  or
+       directory
+
+       This  is  caused  by the way shared library support works on those sys-
+       tems. You need to add
+
+         -R/usr/local/lib
+
+       (for example) to the compile command to get round this problem.

+PCRE DISCUSSION OF STACK USAGE
+
+       When  you call pcre_exec(), it makes use of an internal function called
+       match(). This calls itself recursively at branch points in the pattern,
+       in  order to remember the state of the match so that it can back up and
+       try a different alternative if the first one fails.  As  matching  pro-
+       ceeds  deeper  and deeper into the tree of possibilities, the recursion
+       depth increases.
+
+       Not all calls of match() increase the recursion depth; for an item such
+       as  a* it may be called several times at the same level, after matching
+       different numbers of a's. Furthermore, in a number of cases  where  the
+       result  of  the  recursive call would immediately be passed back as the
+       result of the current call (a "tail recursion"), the function  is  just
+       restarted instead.
+
+       The pcre_dfa_exec() function operates in an entirely different way, and
+       hardly uses recursion at all. The limit on its complexity is the amount
+       of  workspace  it  is  given.  The comments that follow do NOT apply to
+       pcre_dfa_exec(); they are relevant only for pcre_exec().
+
+       You can set limits on the number of times that match() is called,  both
+       in  total  and  recursively. If the limit is exceeded, an error occurs.
+       For details, see the section on  extra  data  for  pcre_exec()  in  the
+       pcreapi documentation.
+
+       Each  time  that match() is actually called recursively, it uses memory
+       from the process stack. For certain kinds of  pattern  and  data,  very
+       large  amounts of stack may be needed, despite the recognition of "tail
+       recursion".  You can often reduce the amount of recursion,  and  there-
+       fore  the  amount of stack used, by modifying the pattern that is being
+       matched. Consider, for example, this pattern:
+
+         ([^<]|<(?!inet))+
+
+       It matches from wherever it starts until it encounters "

+.SH "PCRE API OVERVIEW"
+.rs
+.sp
+PCRE has its own native API, which is described in this document. There are
+also some wrapper functions that correspond to the POSIX regular expression
+API. These are described in the
+.\" HREF
+\fBpcreposix\fP
+.\"
+documentation. Both of these APIs define a set of C function calls. A C++
+wrapper is distributed with PCRE. It is documented in the
+.\" HREF
+\fBpcrecpp\fP
+.\"
+page.
+.P
+The native API C function prototypes are defined in the header file
+\fBpcre.h\fP, and on Unix systems the library itself is called \fBlibpcre\fP.
+It can normally be accessed by adding \fB-lpcre\fP to the command for linking
+an application that uses PCRE. The header file defines the macros PCRE_MAJOR
+and PCRE_MINOR to contain the major and minor release numbers for the library.
+Applications can use these to include support for different releases of PCRE.
+.P
+The functions \fBpcre_compile()\fP, \fBpcre_compile2()\fP, \fBpcre_study()\fP,
+and \fBpcre_exec()\fP are used for compiling and matching regular expressions
+in a Perl-compatible manner. A sample program that demonstrates the simplest
+way of using them is provided in the file called \fIpcredemo.c\fP in the PCRE
+source distribution. A listing of this program is given in the
+.\" HREF
+\fBpcredemo\fP
+.\"
+documentation, and the
+.\" HREF
+\fBpcresample\fP
+.\"
+documentation describes how to compile and run it.
+.P
+A second matching function, \fBpcre_dfa_exec()\fP, which is not
+Perl-compatible, is also provided. This uses a different algorithm for the
+matching. The alternative algorithm finds all possible matches (at a given
+point in the subject), and scans the subject just once (unless there are
+lookbehind assertions). However, this algorithm does not return captured
+substrings. A description of the two matching algorithms and their advantages
+and disadvantages is given in the
+.\" HREF
+\fBpcrematching\fP
+.\"
+documentation.
+.P
+In addition to the main compiling and matching functions, there are convenience
+functions for extracting captured substrings from a subject string that is
+matched by \fBpcre_exec()\fP. They are:
+.sp
+  \fBpcre_copy_substring()\fP
+  \fBpcre_copy_named_substring()\fP
+  \fBpcre_get_substring()\fP
+  \fBpcre_get_named_substring()\fP
+  \fBpcre_get_substring_list()\fP
+  \fBpcre_get_stringnumber()\fP
+  \fBpcre_get_stringtable_entries()\fP
+.sp
+\fBpcre_free_substring()\fP and \fBpcre_free_substring_list()\fP are also
+provided, to free the memory used for extracted strings.
+.P
+The function \fBpcre_maketables()\fP is used to build a set of character tables
+in the current locale for passing to \fBpcre_compile()\fP, \fBpcre_exec()\fP,
+or \fBpcre_dfa_exec()\fP. This is an optional facility that is provided for
+specialist use. Most commonly, no special tables are passed, in which case
+internal tables that are generated when PCRE is built are used.
+.P
+The function \fBpcre_fullinfo()\fP is used to find out information about a
+compiled pattern; \fBpcre_info()\fP is an obsolete version that returns only
+some of the available information, but is retained for backwards compatibility.
+The function \fBpcre_version()\fP returns a pointer to a string containing the
+version of PCRE and its date of release.
+.P
+The function \fBpcre_refcount()\fP maintains a reference count in a data block
+containing a compiled pattern. This is provided for the benefit of
+object-oriented applications.
+.P
+The global variables \fBpcre_malloc\fP and \fBpcre_free\fP initially contain
+the entry points of the standard \fBmalloc()\fP and \fBfree()\fP functions,
+respectively. PCRE calls the memory management functions via these variables,
+so a calling program can replace them if it wishes to intercept the calls. This
+should be done before calling any PCRE functions.
+.P
+The global variables \fBpcre_stack_malloc\fP and \fBpcre_stack_free\fP are also
+indirections to memory management functions. These special functions are used
+only when PCRE is compiled to use the heap for remembering data, instead of
+recursive function calls, when running the \fBpcre_exec()\fP function. See the
+.\" HREF
+\fBpcrebuild\fP
+.\"
+documentation for details of how to do this. It is a non-standard way of
+building PCRE, for use in environments that have limited stacks. Because of the
+greater use of memory management, it runs more slowly. Separate functions are
+provided so that special-purpose external code can be used for this case. When
+used, these functions are always called in a stack-like manner (last obtained,
+first freed), and always for memory blocks of the same size. There is a
+discussion about PCRE's stack usage in the
+.\" HREF
+\fBpcrestack\fP
+.\"
+documentation.
+.P
+The global variable \fBpcre_callout\fP initially contains NULL. It can be set
+by the caller to a "callout" function, which PCRE will then call at specified
+points during a matching operation. Details are given in the
+.\" HREF
+\fBpcrecallout\fP
+.\"
+documentation.
+.
+.
+.\" HTML 
+.SH NEWLINES
+.rs
+.sp
+PCRE supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The Unicode newline sequences are the three just
+mentioned, plus the single characters VT (vertical tab, U+000B), FF (formfeed,
+U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and PS
+(paragraph separator, U+2029).
+.P
+Each of the first three conventions is used by at least one operating system as
+its standard newline sequence. When PCRE is built, a default can be specified.
+The default default is LF, which is the Unix standard. When PCRE is run, the
+default can be overridden, either when a pattern is compiled, or when it is
+matched.
+.P
+At compile time, the newline convention can be specified by the \fIoptions\fP
+argument of \fBpcre_compile()\fP, or it can be specified by special text at the
+start of the pattern itself; this overrides any other settings. See the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+page for details of the special character sequences.
+.P
+In the PCRE documentation the word "newline" is used to mean "the character or
+pair of characters that indicate a line break". The choice of newline
+convention affects the handling of the dot, circumflex, and dollar
+metacharacters, the handling of #-comments in /x mode, and, when CRLF is a
+recognized line ending sequence, the match position advancement for a
+non-anchored pattern. There is more detail about this in the
+.\" HTML 
+.\" 
+section on \fBpcre_exec()\fP options
+.\"
+below.
+.P
+The choice of newline convention does not affect the interpretation of
+the \en or \er escape sequences, nor does it affect what \eR matches, which is
+controlled in a similar way, but by separate options.
+.
+.
+.SH MULTITHREADING
+.rs
+.sp
+The PCRE functions can be used in multi-threading applications, with the
+proviso that the memory management functions pointed to by \fBpcre_malloc\fP,
+\fBpcre_free\fP, \fBpcre_stack_malloc\fP, and \fBpcre_stack_free\fP, and the
+callout function pointed to by \fBpcre_callout\fP, are shared by all threads.
+.P
+The compiled form of a regular expression is not altered during matching, so
+the same compiled pattern can safely be used by several threads at once.
+.
+.
+.SH "SAVING PRECOMPILED PATTERNS FOR LATER USE"
+.rs
+.sp
+The compiled form of a regular expression can be saved and re-used at a later
+time, possibly by a different program, and even on a host other than the one on
+which it was compiled. Details are given in the
+.\" HREF
+\fBpcreprecompile\fP
+.\"
+documentation. However, compiling a regular expression with one version of PCRE
+for use with a different version is not guaranteed to work and may cause
+crashes.
+.
+.
+.SH "CHECKING BUILD-TIME OPTIONS"
+.rs
+.sp
+.B int pcre_config(int \fIwhat\fP, void *\fIwhere\fP);
+.PP
+The function \fBpcre_config()\fP makes it possible for a PCRE client to
+discover which optional features have been compiled into the PCRE library. The
+.\" HREF
+\fBpcrebuild\fP
+.\"
+documentation has more details about these optional features.
+.P
+The first argument for \fBpcre_config()\fP is an integer, specifying which
+information is required; the second argument is a pointer to a variable into
+which the information is placed. The following information is available:
+.sp
+  PCRE_CONFIG_UTF8
+.sp
+The output is an integer that is set to one if UTF-8 support is available;
+otherwise it is set to zero.
+.sp
+  PCRE_CONFIG_UNICODE_PROPERTIES
+.sp
+The output is an integer that is set to one if support for Unicode character
+properties is available; otherwise it is set to zero.
+.sp
+  PCRE_CONFIG_NEWLINE
+.sp
+The output is an integer whose value specifies the default character sequence
+that is recognized as meaning "newline". The four values that are supported
+are: 10 for LF, 13 for CR, 3338 for CRLF, -2 for ANYCRLF, and -1 for ANY.
+Though they are derived from ASCII, the same values are returned in EBCDIC
+environments. The default should normally correspond to the standard sequence
+for your operating system.
+.sp
+  PCRE_CONFIG_BSR
+.sp
+The output is an integer whose value indicates what character sequences the \eR
+escape sequence matches by default. A value of 0 means that \eR matches any
+Unicode line ending sequence; a value of 1 means that \eR matches only CR, LF,
+or CRLF. The default can be overridden when a pattern is compiled or matched.
+.sp
+  PCRE_CONFIG_LINK_SIZE
+.sp
+The output is an integer that contains the number of bytes used for internal
+linkage in compiled regular expressions. The value is 2, 3, or 4. Larger values
+allow larger regular expressions to be compiled, at the expense of slower
+matching. The default value of 2 is sufficient for all but the most massive
+patterns, since it allows the compiled pattern to be up to 64K in size.
+.sp
+  PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
+.sp
+The output is an integer that contains the threshold above which the POSIX
+interface uses \fBmalloc()\fP for output vectors. Further details are given in
+the
+.\" HREF
+\fBpcreposix\fP
+.\"
+documentation.
+.sp
+  PCRE_CONFIG_MATCH_LIMIT
+.sp
+The output is a long integer that gives the default limit for the number of
+internal matching function calls in a \fBpcre_exec()\fP execution. Further
+details are given with \fBpcre_exec()\fP below.
+.sp
+  PCRE_CONFIG_MATCH_LIMIT_RECURSION
+.sp
+The output is a long integer that gives the default limit for the depth of
+recursion when calling the internal matching function in a \fBpcre_exec()\fP
+execution. Further details are given with \fBpcre_exec()\fP below.
+.sp
+  PCRE_CONFIG_STACKRECURSE
+.sp
+The output is an integer that is set to one if internal recursion when running
+\fBpcre_exec()\fP is implemented by recursive function calls that use the stack
+to remember their state. This is the usual way that PCRE is compiled. The
+output is zero if PCRE was compiled to use blocks of data on the heap instead
+of recursive function calls. In this case, \fBpcre_stack_malloc\fP and
+\fBpcre_stack_free\fP are called to manage memory blocks on the heap, thus
+avoiding the use of the stack.

+.ti +5n
+.B const unsigned char *\fItableptr\fP);
+.P
+Either of the functions \fBpcre_compile()\fP or \fBpcre_compile2()\fP can be
+called to compile a pattern into an internal form. The only difference between
+the two interfaces is that \fBpcre_compile2()\fP has an additional argument,
+\fIerrorcodeptr\fP, via which a numerical error code can be returned. To avoid
+too much repetition, we refer just to \fBpcre_compile()\fP below, but the
+information applies equally to \fBpcre_compile2()\fP.
+.P
+The pattern is a C string terminated by a binary zero, and is passed in the
+\fIpattern\fP argument. A pointer to a single block of memory that is obtained
+via \fBpcre_malloc\fP is returned. This contains the compiled code and related
+data. The \fBpcre\fP type is defined for the returned block; this is a typedef
+for a structure whose contents are not externally defined. It is up to the
+caller to free the memory (via \fBpcre_free\fP) when it is no longer required.
+.P
+Although the compiled code of a PCRE regex is relocatable, that is, it does not
+depend on memory location, the complete \fBpcre\fP data block is not
+fully relocatable, because it may contain a copy of the \fItableptr\fP
+argument, which is an address (see below).
+.P
+The \fIoptions\fP argument contains various bit settings that affect the
+compilation. It should be zero if no options are required. The available
+options are described below. Some of them (in particular, those that are
+compatible with Perl, but some others as well) can also be set and unset from
+within the pattern (see the detailed description in the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+documentation). For those options that can be different in different parts of
+the pattern, the contents of the \fIoptions\fP argument specifies their
+settings at the start of compilation and execution. The PCRE_ANCHORED,
+PCRE_BSR_\fIxxx\fP, and PCRE_NEWLINE_\fIxxx\fP options can be set at the time
+of matching as well as at compile time.
+.P
+If \fIerrptr\fP is NULL, \fBpcre_compile()\fP returns NULL immediately.
+Otherwise, if compilation of a pattern fails, \fBpcre_compile()\fP returns
+NULL, and sets the variable pointed to by \fIerrptr\fP to point to a textual
+error message. This is a static string that is part of the library. You must
+not try to free it. The byte offset from the start of the pattern to the
+character that was being processed when the error was discovered is placed in
+the variable pointed to by \fIerroffset\fP, which must not be NULL. If it is,
+an immediate error is given. Some errors are not detected until checks are
+carried out when the whole pattern has been scanned; in this case the offset is
+set to the end of the pattern.
+.P
+If \fBpcre_compile2()\fP is used instead of \fBpcre_compile()\fP, and the
+\fIerrorcodeptr\fP argument is not NULL, a non-zero error code number is
+returned via this argument in the event of an error. This is in addition to the
+textual error message. Error codes and messages are listed below.
+.P
+If the final argument, \fItableptr\fP, is NULL, PCRE uses a default set of
+character tables that are built when PCRE is compiled, using the default C
+locale. Otherwise, \fItableptr\fP must be an address that is the result of a
+call to \fBpcre_maketables()\fP. This value is stored with the compiled
+pattern, and used again by \fBpcre_exec()\fP, unless another table pointer is
+passed to it. For more discussion, see the section on locale support below.
+.P
+This code fragment shows a typical straightforward call to \fBpcre_compile()\fP:
+.sp
+  pcre *re;
+  const char *error;
+  int erroffset;
+  re = pcre_compile(
+    "^A.*Z",          /* the pattern */
+    0,                /* default options */
+    &error,           /* for error message */
+    &erroffset,       /* for error offset */
+    NULL);            /* use default character tables */
+.sp
+The following names for option bits are defined in the \fBpcre.h\fP header
+file:
+.sp
+  PCRE_ANCHORED
+.sp
+If this bit is set, the pattern is forced to be "anchored", that is, it is
+constrained to match only at the first matching point in the string that is
+being searched (the "subject string"). This effect can also be achieved by
+appropriate constructs in the pattern itself, which is the only way to do it in
+Perl.
+.sp
+  PCRE_AUTO_CALLOUT
+.sp
+If this bit is set, \fBpcre_compile()\fP automatically inserts callout items,
+all with number 255, before each pattern item. For discussion of the callout
+facility, see the
+.\" HREF
+\fBpcrecallout\fP
+.\"
+documentation.
+.sp
+  PCRE_BSR_ANYCRLF
+  PCRE_BSR_UNICODE
+.sp
+These options (which are mutually exclusive) control what the \eR escape
+sequence matches. The choice is either to match only CR, LF, or CRLF, or to
+match any Unicode newline sequence. The default is specified when PCRE is
+built. It can be overridden from within the pattern, or by setting an option
+when a compiled pattern is matched.
+.sp
+  PCRE_CASELESS
+.sp
+If this bit is set, letters in the pattern match both upper and lower case
+letters. It is equivalent to Perl's /i option, and it can be changed within a
+pattern by a (?i) option setting. In UTF-8 mode, PCRE always understands the
+concept of case for characters whose values are less than 128, so caseless
+matching is always possible. For characters with higher values, the concept of
+case is supported if PCRE is compiled with Unicode property support, but not
+otherwise. If you want to use caseless matching for characters 128 and above,
+you must ensure that PCRE is compiled with Unicode property support as well as
+with UTF-8 support.
+.sp
+  PCRE_DOLLAR_ENDONLY
+.sp
+If this bit is set, a dollar metacharacter in the pattern matches only at the
+end of the subject string. Without this option, a dollar also matches
+immediately before a newline at the end of the string (but not before any other
+newlines). The PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set.
+There is no equivalent to this option in Perl, and no way to set it within a
+pattern.
+.sp
+  PCRE_DOTALL
+.sp
+If this bit is set, a dot metacharater in the pattern matches all characters,
+including those that indicate newline. Without it, a dot does not match when
+the current position is at a newline. This option is equivalent to Perl's /s
+option, and it can be changed within a pattern by a (?s) option setting. A
+negative class such as [^a] always matches newline characters, independent of
+the setting of this option.
+.sp
+  PCRE_DUPNAMES
+.sp
+If this bit is set, names used to identify capturing subpatterns need not be
+unique. This can be helpful for certain types of pattern when it is known that
+only one instance of the named subpattern can ever be matched. There are more
+details of named subpatterns below; see also the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+documentation.
+.sp
+  PCRE_EXTENDED
+.sp
+If this bit is set, whitespace data characters in the pattern are totally
+ignored except when escaped or inside a character class. Whitespace does not
+include the VT character (code 11). In addition, characters between an
+unescaped # outside a character class and the next newline, inclusive, are also
+ignored. This is equivalent to Perl's /x option, and it can be changed within a
+pattern by a (?x) option setting.
+.P
+This option makes it possible to include comments inside complicated patterns.
+Note, however, that this applies only to data characters. Whitespace characters
+may never appear within special character sequences in a pattern, for example
+within the sequence (?( which introduces a conditional subpattern.
+.sp
+  PCRE_EXTRA
+.sp
+This option was invented in order to turn on additional functionality of PCRE
+that is incompatible with Perl, but it is currently of very little use. When
+set, any backslash in a pattern that is followed by a letter that has no
+special meaning causes an error, thus reserving these combinations for future
+expansion. By default, as in Perl, a backslash followed by a letter with no
+special meaning is treated as a literal. (Perl can, however, be persuaded to
+give a warning for this.) There are at present no other features controlled by
+this option. It can also be set by a (?X) option setting within a pattern.
+.sp
+  PCRE_FIRSTLINE
+.sp
+If this option is set, an unanchored pattern is required to match before or at
+the first newline in the subject string, though the matched text may continue
+over the newline.
+.sp
+  PCRE_JAVASCRIPT_COMPAT
+.sp
+If this option is set, PCRE's behaviour is changed in some ways so that it is
+compatible with JavaScript rather than Perl. The changes are as follows:
+.P
+(1) A lone closing square bracket in a pattern causes a compile-time error,
+because this is illegal in JavaScript (by default it is treated as a data
+character). Thus, the pattern AB]CD becomes illegal when this option is set.
+.P
+(2) At run time, a back reference to an unset subpattern group matches an empty
+string (by default this causes the current matching alternative to fail). A
+pattern such as (\e1)(a) succeeds when this option is set (assuming it can find
+an "a" in the subject), whereas it fails by default, for Perl compatibility.
+.sp
+  PCRE_MULTILINE
+.sp
+By default, PCRE treats the subject string as consisting of a single line of
+characters (even if it actually contains newlines). The "start of line"
+metacharacter (^) matches only at the start of the string, while the "end of
+line" metacharacter ($) matches only at the end of the string, or before a
+terminating newline (unless PCRE_DOLLAR_ENDONLY is set). This is the same as
+Perl.
+.P
+When PCRE_MULTILINE it is set, the "start of line" and "end of line" constructs
+match immediately following or immediately before internal newlines in the
+subject string, respectively, as well as at the very start and end. This is
+equivalent to Perl's /m option, and it can be changed within a pattern by a
+(?m) option setting. If there are no newlines in a subject string, or no
+occurrences of ^ or $ in a pattern, setting PCRE_MULTILINE has no effect.
+.sp
+  PCRE_NEWLINE_CR
+  PCRE_NEWLINE_LF
+  PCRE_NEWLINE_CRLF
+  PCRE_NEWLINE_ANYCRLF
+  PCRE_NEWLINE_ANY
+.sp
+These options override the default newline definition that was chosen when PCRE
+was built. Setting the first or the second specifies that a newline is
+indicated by a single character (CR or LF, respectively). Setting
+PCRE_NEWLINE_CRLF specifies that a newline is indicated by the two-character
+CRLF sequence. Setting PCRE_NEWLINE_ANYCRLF specifies that any of the three
+preceding sequences should be recognized. Setting PCRE_NEWLINE_ANY specifies
+that any Unicode newline sequence should be recognized. The Unicode newline
+sequences are the three just mentioned, plus the single characters VT (vertical
+tab, U+000B), FF (formfeed, U+000C), NEL (next line, U+0085), LS (line
+separator, U+2028), and PS (paragraph separator, U+2029). The last two are
+recognized only in UTF-8 mode.
+.P
+The newline setting in the options word uses three bits that are treated
+as a number, giving eight possibilities. Currently only six are used (default
+plus the five values above). This means that if you set more than one newline
+option, the combination may or may not be sensible. For example,
+PCRE_NEWLINE_CR with PCRE_NEWLINE_LF is equivalent to PCRE_NEWLINE_CRLF, but
+other combinations may yield unused numbers and cause an error.
+.P
+The only time that a line break is specially recognized when compiling a
+pattern is if PCRE_EXTENDED is set, and an unescaped # outside a character
+class is encountered. This indicates a comment that lasts until after the next
+line break sequence. In other circumstances, line break sequences are treated
+as literal data, except that in PCRE_EXTENDED mode, both CR and LF are treated
+as whitespace characters and are therefore ignored.
+.P
+The newline option that is set at compile time becomes the default that is used
+for \fBpcre_exec()\fP and \fBpcre_dfa_exec()\fP, but it can be overridden.
+.sp
+  PCRE_NO_AUTO_CAPTURE
+.sp
+If this option is set, it disables the use of numbered capturing parentheses in
+the pattern. Any opening parenthesis that is not followed by ? behaves as if it
+were followed by ?: but named parentheses can still be used for capturing (and
+they acquire numbers in the usual way). There is no equivalent of this option
+in Perl.
+.sp
+  PCRE_UNGREEDY
+.sp
+This option inverts the "greediness" of the quantifiers so that they are not
+greedy by default, but become greedy if followed by "?". It is not compatible
+with Perl. It can also be set by a (?U) option setting within the pattern.
+.sp
+  PCRE_UTF8
+.sp
+This option causes PCRE to regard both the pattern and the subject as strings
+of UTF-8 characters instead of single-byte character strings. However, it is
+available only when PCRE is built to include UTF-8 support. If not, the use
+of this option provokes an error. Details of how this option changes the
+behaviour of PCRE are given in the
+.\" HTML 
+.\" 
+section on UTF-8 support
+.\"
+in the main
+.\" HREF
+\fBpcre\fP
+.\"
+page.
+.sp
+  PCRE_NO_UTF8_CHECK
+.sp
+When PCRE_UTF8 is set, the validity of the pattern as a UTF-8 string is
+automatically checked. There is a discussion about the
+.\" HTML 
+.\" 
+validity of UTF-8 strings
+.\"
+in the main
+.\" HREF
+\fBpcre\fP
+.\"
+page. If an invalid UTF-8 sequence of bytes is found, \fBpcre_compile()\fP
+returns an error. If you already know that your pattern is valid, and you want
+to skip this check for performance reasons, you can set the PCRE_NO_UTF8_CHECK
+option. When it is set, the effect of passing an invalid UTF-8 string as a
+pattern is undefined. It may cause your program to crash. Note that this option
+can also be passed to \fBpcre_exec()\fP and \fBpcre_dfa_exec()\fP, to suppress
+the UTF-8 validity checking of subject strings.

+.PP
+If a compiled pattern is going to be used several times, it is worth spending
+more time analyzing it in order to speed up the time taken for matching. The
+function \fBpcre_study()\fP takes a pointer to a compiled pattern as its first
+argument. If studying the pattern produces additional information that will
+help speed up matching, \fBpcre_study()\fP returns a pointer to a
+\fBpcre_extra\fP block, in which the \fIstudy_data\fP field points to the
+results of the study.
+.P
+The returned value from \fBpcre_study()\fP can be passed directly to
+\fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP. However, a \fBpcre_extra\fP block

+in the section on matching a pattern.
+.P
+If studying the pattern does not produce any useful information,
+\fBpcre_study()\fP returns NULL. In that circumstance, if the calling program

+\fBpcre_dfa_exec()\fP, it must set up its own \fBpcre_extra\fP block.
+.P
+The second argument of \fBpcre_study()\fP contains option bits. At present, no

+.P
+The third argument for \fBpcre_study()\fP is a pointer for an error message. If

+set to NULL. Otherwise it is set to point to a textual error message. This is a
+static string that is part of the library. You must not try to free it. You
+should test the error pointer for NULL after calling \fBpcre_study()\fP, to be

+.sp
+Studying a pattern does two things: first, a lower bound for the length of
+subject string that is needed to match the pattern is computed. This does not
+mean that there are any strings of that length that match, but it does
+guarantee that no shorter strings match. The value is used by
+\fBpcre_exec()\fP and \fBpcre_dfa_exec()\fP to avoid wasting time by trying to
+match strings that are shorter than the lower bound. You can find out the value
+in a calling program via the \fBpcre_fullinfo()\fP function.
+.P
+Studying a pattern is also useful for non-anchored patterns that do not have a
+single fixed starting character. A bitmap of possible starting bytes is
+created. This speeds up finding a position in the subject at which to start
+matching.
+.
+.
+.\" HTML 
+.SH "LOCALE SUPPORT"
+.rs
+.sp
+PCRE handles caseless matching, and determines whether characters are letters,
+digits, or whatever, by reference to a set of tables, indexed by character
+value. When running in UTF-8 mode, this applies only to characters with codes
+less than 128. Higher-valued codes never match escapes such as \ew or \ed, but
+can be tested with \ep if PCRE is built with Unicode character property
+support. The use of locales with Unicode is discouraged. If you are handling
+characters with codes greater than 128, you should either use UTF-8 and
+Unicode, or use locales, but not try to mix the two.
+.P
+PCRE contains an internal set of tables that are used when the final argument
+of \fBpcre_compile()\fP is NULL. These are sufficient for many applications.
+Normally, the internal tables recognize only ASCII characters. However, when
+PCRE is built, it is possible to cause the internal tables to be rebuilt in the
+default "C" locale of the local system, which may cause them to be different.
+.P
+The internal tables can always be overridden by tables supplied by the
+application that calls PCRE. These may be created in a different locale from
+the default. As more and more applications change to using Unicode, the need
+for this locale support is expected to die away.
+.P
+External tables are built by calling the \fBpcre_maketables()\fP function,
+which has no arguments, in the relevant locale. The result can then be passed
+to \fBpcre_compile()\fP or \fBpcre_exec()\fP as often as necessary. For
+example, to build and use tables that are appropriate for the French locale
+(where accented characters with values greater than 128 are treated as letters),
+the following code could be used:
+.sp
+  setlocale(LC_CTYPE, "fr_FR");
+  tables = pcre_maketables();
+  re = pcre_compile(..., tables);
+.sp
+The locale name "fr_FR" is used on Linux and other Unix-like systems; if you
+are using Windows, the name for the French locale is "french".
+.P
+When \fBpcre_maketables()\fP runs, the tables are built in memory that is
+obtained via \fBpcre_malloc\fP. It is the caller's responsibility to ensure
+that the memory containing the tables remains available for as long as it is
+needed.
+.P
+The pointer that is passed to \fBpcre_compile()\fP is saved with the compiled
+pattern, and the same tables are used via this pointer by \fBpcre_study()\fP
+and normally also by \fBpcre_exec()\fP. Thus, by default, for any single
+pattern, compilation, studying and matching all happen in the same locale, but
+different patterns can be compiled in different locales.
+.P
+It is possible to pass a table pointer or NULL (indicating the use of the
+internal tables) to \fBpcre_exec()\fP. Although not intended for this purpose,
+this facility could be used to match a pattern in a different locale from the
+one in which it was compiled. Passing table pointers at run time is discussed
+below in the section on matching a pattern.

+.sp
+The possible values for the third argument are defined in \fBpcre.h\fP, and are
+as follows:
+.sp
+  PCRE_INFO_BACKREFMAX
+.sp
+Return the number of the highest back reference in the pattern. The fourth
+argument should point to an \fBint\fP variable. Zero is returned if there are
+no back references.
+.sp
+  PCRE_INFO_CAPTURECOUNT
+.sp
+Return the number of capturing subpatterns in the pattern. The fourth argument
+should point to an \fBint\fP variable.
+.sp
+  PCRE_INFO_DEFAULT_TABLES
+.sp
+Return a pointer to the internal default character tables within PCRE. The
+fourth argument should point to an \fBunsigned char *\fP variable. This
+information call is provided for internal use by the \fBpcre_study()\fP
+function. External callers can cause PCRE to use its internal tables by passing
+a NULL table pointer.
+.sp
+  PCRE_INFO_FIRSTBYTE
+.sp
+Return information about the first byte of any matched string, for a
+non-anchored pattern. The fourth argument should point to an \fBint\fP
+variable. (This option used to be called PCRE_INFO_FIRSTCHAR; the old name is
+still recognized for backwards compatibility.)
+.P
+If there is a fixed first byte, for example, from a pattern such as
+(cat|cow|coyote), its value is returned. Otherwise, if either
+.sp
+(a) the pattern was compiled with the PCRE_MULTILINE option, and every branch
+starts with "^", or
+.sp
+(b) every branch of the pattern starts with ".*" and PCRE_DOTALL is not set
+(if it were set, the pattern would be anchored),
+.sp
+-1 is returned, indicating that the pattern matches only at the start of a
+subject string or after any newline within the string. Otherwise -2 is
+returned. For anchored patterns, -2 is returned.
+.sp
+  PCRE_INFO_FIRSTTABLE
+.sp
+If the pattern was studied, and this resulted in the construction of a 256-bit
+table indicating a fixed set of bytes for the first byte in any matching
+string, a pointer to the table is returned. Otherwise NULL is returned. The
+fourth argument should point to an \fBunsigned char *\fP variable.
+.sp
+  PCRE_INFO_HASCRORLF
+.sp
+Return 1 if the pattern contains any explicit matches for CR or LF characters,
+otherwise 0. The fourth argument should point to an \fBint\fP variable. An
+explicit match is either a literal CR or LF character, or \er or \en.
+.sp
+  PCRE_INFO_JCHANGED
+.sp
+Return 1 if the (?J) or (?-J) option setting is used in the pattern, otherwise
+0. The fourth argument should point to an \fBint\fP variable. (?J) and
+(?-J) set and unset the local PCRE_DUPNAMES option, respectively.
+.sp
+  PCRE_INFO_LASTLITERAL
+.sp
+Return the value of the rightmost literal byte that must exist in any matched
+string, other than at its start, if such a byte has been recorded. The fourth
+argument should point to an \fBint\fP variable. If there is no such byte, -1 is
+returned. For anchored patterns, a last literal byte is recorded only if it
+follows something of variable length. For example, for the pattern
+/^a\ed+z\ed+/ the returned value is "z", but for /^a\edz\ed/ the returned value
+is -1.
+.sp
+  PCRE_INFO_MINLENGTH
+.sp
+If the pattern was studied and a minimum length for matching subject strings
+was computed, its value is returned. Otherwise the returned value is -1. The
+value is a number of characters, not bytes (this may be relevant in UTF-8
+mode). The fourth argument should point to an \fBint\fP variable. A
+non-negative value is a lower bound to the length of any matching string. There
+may not be any strings of that length that do actually match, but every string
+that does match is at least that long.
+.sp
+  PCRE_INFO_NAMECOUNT
+  PCRE_INFO_NAMEENTRYSIZE
+  PCRE_INFO_NAMETABLE
+.sp
+PCRE supports the use of named as well as numbered capturing parentheses. The
+names are just an additional way of identifying the parentheses, which still
+acquire numbers. Several convenience functions such as
+\fBpcre_get_named_substring()\fP are provided for extracting captured
+substrings by name. It is also possible to extract the data directly, by first
+converting the name to a number in order to access the correct pointers in the
+output vector (described with \fBpcre_exec()\fP below). To do the conversion,
+you need to use the name-to-number map, which is described by these three
+values.
+.P
+The map consists of a number of fixed-size entries. PCRE_INFO_NAMECOUNT gives
+the number of entries, and PCRE_INFO_NAMEENTRYSIZE gives the size of each
+entry; both of these return an \fBint\fP value. The entry size depends on the
+length of the longest name. PCRE_INFO_NAMETABLE returns a pointer to the first
+entry of the table (a pointer to \fBchar\fP). The first two bytes of each entry
+are the number of the capturing parenthesis, most significant byte first. The
+rest of the entry is the corresponding name, zero terminated.
+.P
+The names are in alphabetical order. Duplicate names may appear if (?| is used
+to create multiple groups with the same number, as described in the
+.\" HTML 
+.\" 
+section on duplicate subpattern numbers
+.\"
+in the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+page. Duplicate names for subpatterns with different numbers are permitted only
+if PCRE_DUPNAMES is set. In all cases of duplicate names, they appear in the
+table in the order in which they were found in the pattern. In the absence of
+(?| this is the order of increasing number; when (?| is used this is not
+necessarily the case because later subpatterns may have lower numbers.
+.P
+As a simple example of the name/number table, consider the following pattern
+(assume PCRE_EXTENDED is set, so white space - including newlines - is
+ignored):
+.sp
+.\" JOIN
+  (? (?(\ed\ed)?\ed\ed) -
+  (?\ed\ed) - (?\ed\ed) )
+.sp
+There are four named subpatterns, so the table has four entries, and each entry
+in the table is eight bytes long. The table is as follows, with non-printing
+bytes shows in hexadecimal, and undefined bytes shown as ??:
+.sp
+  00 01 d  a  t  e  00 ??
+  00 05 d  a  y  00 ?? ??
+  00 04 m  o  n  t  h  00
+  00 02 y  e  a  r  00 ??
+.sp
+When writing code to extract data from named subpatterns using the
+name-to-number map, remember that the length of the entries is likely to be
+different for each compiled pattern.
+.sp
+  PCRE_INFO_OKPARTIAL
+.sp
+Return 1 if the pattern can be used for partial matching with
+\fBpcre_exec()\fP, otherwise 0. The fourth argument should point to an
+\fBint\fP variable. From release 8.00, this always returns 1, because the
+restrictions that previously applied to partial matching have been lifted. The
+.\" HREF
+\fBpcrepartial\fP
+.\"
+documentation gives details of partial matching.
+.sp
+  PCRE_INFO_OPTIONS
+.sp
+Return a copy of the options with which the pattern was compiled. The fourth
+argument should point to an \fBunsigned long int\fP variable. These option bits
+are those specified in the call to \fBpcre_compile()\fP, modified by any
+top-level option settings at the start of the pattern itself. In other words,
+they are the options that will be in force when matching starts. For example,
+if the pattern /(?im)abc(?-i)d/ is compiled with the PCRE_EXTENDED option, the
+result is PCRE_CASELESS, PCRE_MULTILINE, and PCRE_EXTENDED.
+.P
+A pattern is automatically anchored by PCRE if all of its top-level
+alternatives begin with one of the following:
+.sp
+  ^     unless PCRE_MULTILINE is set
+  \eA    always
+  \eG    always
+.\" JOIN
+  .*    if PCRE_DOTALL is set and there are no back
+          references to the subpattern in which .* appears
+.sp
+For such patterns, the PCRE_ANCHORED bit is set in the options returned by
+\fBpcre_fullinfo()\fP.
+.sp
+  PCRE_INFO_SIZE
+.sp
+Return the size of the compiled pattern, that is, the value that was passed as
+the argument to \fBpcre_malloc()\fP when PCRE was getting memory in which to
+place the compiled data. The fourth argument should point to a \fBsize_t\fP
+variable.
+.sp
+  PCRE_INFO_STUDYSIZE
+.sp
+Return the size of the data block pointed to by the \fIstudy_data\fP field in
+a \fBpcre_extra\fP block. That is, it is the value that was passed to
+\fBpcre_malloc()\fP when PCRE was getting memory into which to place the data
+created by \fBpcre_study()\fP. If \fBpcre_extra\fP is NULL, or there is no
+study data, zero is returned. The fourth argument should point to a
+\fBsize_t\fP variable.

+.PP
+The \fBpcre_info()\fP function is now obsolete because its interface is too
+restrictive to return all the available data about a compiled pattern. New

+The \fBpcre_refcount()\fP function is used to maintain a reference count in the
+data block that contains a compiled pattern. It is provided for the benefit of
+applications that operate in an object-oriented manner, where different parts
+of the application may be using the same compiled pattern, but you want to free
+the block when they are all done.
+.P
+When a pattern is compiled, the reference count field is initialized to zero.
+It is changed only by calling this function, whose action is to add the
+\fIadjust\fP value (which may be positive or negative) to it. The yield of the
+function is the new value. However, the value of the count is constrained to
+lie between 0 and 65535, inclusive. If the new value is outside these limits,
+it is forced to the appropriate limit value.
+.P
+Except when it is zero, the reference count is not correctly preserved if a

+In most applications, the pattern will have been compiled (and optionally

+.
+.\" HTML 
+.SS "Extra data for \fBpcre_exec()\fR"
+.rs
+.sp
+If the \fIextra\fP argument is not NULL, it must point to a \fBpcre_extra\fP
+data block. The \fBpcre_study()\fP function returns such a block (when it
+doesn't return NULL), but you can also create one for yourself, and pass
+additional information in it. The \fBpcre_extra\fP block contains the following
+fields (not necessarily in this order):
+.sp
+  unsigned long int \fIflags\fP;
+  void *\fIstudy_data\fP;
+  unsigned long int \fImatch_limit\fP;
+  unsigned long int \fImatch_limit_recursion\fP;
+  void *\fIcallout_data\fP;
+  const unsigned char *\fItables\fP;
+.sp
+The \fIflags\fP field is a bitmap that specifies which of the other fields
+are set. The flag bits are:
+.sp
+  PCRE_EXTRA_STUDY_DATA
+  PCRE_EXTRA_MATCH_LIMIT
+  PCRE_EXTRA_MATCH_LIMIT_RECURSION
+  PCRE_EXTRA_CALLOUT_DATA
+  PCRE_EXTRA_TABLES
+.sp
+Other flag bits should be set to zero. The \fIstudy_data\fP field is set in the
+\fBpcre_extra\fP block that is returned by \fBpcre_study()\fP, together with
+the appropriate flag bit. You should not set this yourself, but you may add to
+the block by setting the other fields and their corresponding flag bits.
+.P
+The \fImatch_limit\fP field provides a means of preventing PCRE from using up a
+vast amount of resources when running patterns that are not going to match,
+but which have a very large number of possibilities in their search trees. The
+classic example is a pattern that uses nested unlimited repeats.
+.P
+Internally, PCRE uses a function called \fBmatch()\fP which it calls repeatedly
+(sometimes recursively). The limit set by \fImatch_limit\fP is imposed on the
+number of times this function is called during a match, which has the effect of
+limiting the amount of backtracking that can take place. For patterns that are
+not anchored, the count restarts from zero for each position in the subject
+string.
+.P
+The default value for the limit can be set when PCRE is built; the default
+default is 10 million, which handles all but the most extreme cases. You can
+override the default by suppling \fBpcre_exec()\fP with a \fBpcre_extra\fP
+block in which \fImatch_limit\fP is set, and PCRE_EXTRA_MATCH_LIMIT is set in
+the \fIflags\fP field. If the limit is exceeded, \fBpcre_exec()\fP returns
+PCRE_ERROR_MATCHLIMIT.
+.P
+The \fImatch_limit_recursion\fP field is similar to \fImatch_limit\fP, but
+instead of limiting the total number of times that \fBmatch()\fP is called, it
+limits the depth of recursion. The recursion depth is a smaller number than the
+total number of calls, because not all calls to \fBmatch()\fP are recursive.
+This limit is of use only if it is set smaller than \fImatch_limit\fP.
+.P
+Limiting the recursion depth limits the amount of stack that can be used, or,
+when PCRE has been compiled to use memory on the heap instead of the stack, the
+amount of heap memory that can be used.
+.P
+The default value for \fImatch_limit_recursion\fP can be set when PCRE is
+built; the default default is the same value as the default for
+\fImatch_limit\fP. You can override the default by suppling \fBpcre_exec()\fP
+with a \fBpcre_extra\fP block in which \fImatch_limit_recursion\fP is set, and
+PCRE_EXTRA_MATCH_LIMIT_RECURSION is set in the \fIflags\fP field. If the limit
+is exceeded, \fBpcre_exec()\fP returns PCRE_ERROR_RECURSIONLIMIT.
+.P
+The \fIcallout_data\fP field is used in conjunction with the "callout" feature,
+and is described in the
+.\" HREF
+\fBpcrecallout\fP
+.\"
+documentation.
+.P
+The \fItables\fP field is used to pass a character tables pointer to
+\fBpcre_exec()\fP; this overrides the value that is stored with the compiled
+pattern. A non-NULL value is stored with the compiled pattern only if custom
+tables were supplied to \fBpcre_compile()\fP via its \fItableptr\fP argument.
+If NULL is passed to \fBpcre_exec()\fP using this mechanism, it forces PCRE's
+internal tables to be used. This facility is helpful when re-using patterns
+that have been saved after compiling with an external set of tables, because
+the external tables might be at a different address when \fBpcre_exec()\fP is
+called. See the
+.\" HREF

+.\" HTML 
+.SS "Option bits for \fBpcre_exec()\fP"
+.rs
+.sp
+The unused bits of the \fIoptions\fP argument for \fBpcre_exec()\fP must be
+zero. The only bits that may be set are PCRE_ANCHORED, PCRE_NEWLINE_\fIxxx\fP,
+PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY, PCRE_NOTEMPTY_ATSTART,
+PCRE_NO_START_OPTIMIZE, PCRE_NO_UTF8_CHECK, PCRE_PARTIAL_SOFT, and
+PCRE_PARTIAL_HARD.
+.sp
+  PCRE_ANCHORED
+.sp
+The PCRE_ANCHORED option limits \fBpcre_exec()\fP to matching at the first
+matching position. If a pattern was compiled with PCRE_ANCHORED, or turned out
+to be anchored by virtue of its contents, it cannot be made unachored at
+matching time.
+.sp
+  PCRE_BSR_ANYCRLF
+  PCRE_BSR_UNICODE
+.sp
+These options (which are mutually exclusive) control what the \eR escape
+sequence matches. The choice is either to match only CR, LF, or CRLF, or to
+match any Unicode newline sequence. These options override the choice that was
+made or defaulted when the pattern was compiled.
+.sp
+  PCRE_NEWLINE_CR
+  PCRE_NEWLINE_LF
+  PCRE_NEWLINE_CRLF
+  PCRE_NEWLINE_ANYCRLF
+  PCRE_NEWLINE_ANY
+.sp
+These options override the newline definition that was chosen or defaulted when
+the pattern was compiled. For details, see the description of
+\fBpcre_compile()\fP above. During matching, the newline choice affects the
+behaviour of the dot, circumflex, and dollar metacharacters. It may also alter
+the way the match position is advanced after a match failure for an unanchored
+pattern.
+.P
+When PCRE_NEWLINE_CRLF, PCRE_NEWLINE_ANYCRLF, or PCRE_NEWLINE_ANY is set, and a
+match attempt for an unanchored pattern fails when the current position is at a
+CRLF sequence, and the pattern contains no explicit matches for CR or LF
+characters, the match position is advanced by two characters instead of one, in
+other words, to after the CRLF.
+.P
+The above rule is a compromise that makes the most common cases work as
+expected. For example, if the pattern is .+A (and the PCRE_DOTALL option is not
+set), it does not match the string "\er\enA" because, after failing at the
+start, it skips both the CR and the LF before retrying. However, the pattern
+[\er\en]A does match that string, because it contains an explicit CR or LF
+reference, and so advances only by one character after the first failure.
+.P
+An explicit match for CR of LF is either a literal appearance of one of those
+characters, or one of the \er or \en escape sequences. Implicit matches such as
+[^X] do not count, nor does \es (which includes CR and LF in the characters
+that it matches).
+.P
+Notwithstanding the above, anomalous effects may still occur when CRLF is a
+valid newline sequence and explicit \er or \en escapes appear in the pattern.
+.sp
+  PCRE_NOTBOL
+.sp
+This option specifies that first character of the subject string is not the
+beginning of a line, so the circumflex metacharacter should not match before
+it. Setting this without PCRE_MULTILINE (at compile time) causes circumflex
+never to match. This option affects only the behaviour of the circumflex
+metacharacter. It does not affect \eA.
+.sp
+  PCRE_NOTEOL
+.sp
+This option specifies that the end of the subject string is not the end of a
+line, so the dollar metacharacter should not match it nor (except in multiline
+mode) a newline immediately before it. Setting this without PCRE_MULTILINE (at
+compile time) causes dollar never to match. This option affects only the
+behaviour of the dollar metacharacter. It does not affect \eZ or \ez.
+.sp
+  PCRE_NOTEMPTY
+.sp
+An empty string is not considered to be a valid match if this option is set. If
+there are alternatives in the pattern, they are tried. If all the alternatives
+match the empty string, the entire match fails. For example, if the pattern
+.sp
+  a?b?
+.sp
+is applied to a string not beginning with "a" or "b", it matches an empty
+string at the start of the subject. With PCRE_NOTEMPTY set, this match is not
+valid, so PCRE searches further into the string for occurrences of "a" or "b".
+.sp
+  PCRE_NOTEMPTY_ATSTART
+.sp
+This is like PCRE_NOTEMPTY, except that an empty string match that is not at
+the start of the subject is permitted. If the pattern is anchored, such a match
+can occur only if the pattern contains \eK.
+.P
+Perl has no direct equivalent of PCRE_NOTEMPTY or PCRE_NOTEMPTY_ATSTART, but it
+does make a special case of a pattern match of the empty string within its
+\fBsplit()\fP function, and when using the /g modifier. It is possible to
+emulate Perl's behaviour after matching a null string by first trying the match
+again at the same offset with PCRE_NOTEMPTY_ATSTART and PCRE_ANCHORED, and then
+if that fails, by advancing the starting offset (see below) and trying an
+ordinary match again. There is some code that demonstrates how to do this in
+the
+.\" HREF
+\fBpcredemo\fP
+.\"
+sample program.
+.sp
+  PCRE_NO_START_OPTIMIZE
+.sp
+There are a number of optimizations that \fBpcre_exec()\fP uses at the start of
+a match, in order to speed up the process. For example, if it is known that a
+match must start with a specific character, it searches the subject for that
+character, and fails immediately if it cannot find it, without actually running
+the main matching function. When callouts are in use, these optimizations can
+cause them to be skipped. This option disables the "start-up" optimizations,
+causing performance to suffer, but ensuring that the callouts do occur.
+.sp
+  PCRE_NO_UTF8_CHECK
+.sp
+When PCRE_UTF8 is set at compile time, the validity of the subject as a UTF-8
+string is automatically checked when \fBpcre_exec()\fP is subsequently called.
+The value of \fIstartoffset\fP is also checked to ensure that it points to the
+start of a UTF-8 character. There is a discussion about the validity of UTF-8
+strings in the
+.\" HTML 
+.\" 
+section on UTF-8 support
+.\"
+in the main
+.\" HREF
+\fBpcre\fP
+.\"
+page. If an invalid UTF-8 sequence of bytes is found, \fBpcre_exec()\fP returns
+the error PCRE_ERROR_BADUTF8. If \fIstartoffset\fP contains an invalid value,
+PCRE_ERROR_BADUTF8_OFFSET is returned.
+.P
+If you already know that your subject is valid, and you want to skip these
+checks for performance reasons, you can set the PCRE_NO_UTF8_CHECK option when
+calling \fBpcre_exec()\fP. You might want to do this for the second and
+subsequent calls to \fBpcre_exec()\fP if you are making repeated calls to find
+all the matches in a single subject string. However, you should be sure that
+the value of \fIstartoffset\fP points to the start of a UTF-8 character. When
+PCRE_NO_UTF8_CHECK is set, the effect of passing an invalid UTF-8 string as a
+subject, or a value of \fIstartoffset\fP that does not point to the start of a
+UTF-8 character, is undefined. Your program may crash.
+.sp
+  PCRE_PARTIAL_HARD
+  PCRE_PARTIAL_SOFT
+.sp
+These options turn on the partial matching feature. For backwards
+compatibility, PCRE_PARTIAL is a synonym for PCRE_PARTIAL_SOFT. A partial match
+occurs if the end of the subject string is reached successfully, but there are
+not enough subject characters to complete the match. If this happens when
+PCRE_PARTIAL_HARD is set, \fBpcre_exec()\fP immediately returns
+PCRE_ERROR_PARTIAL. Otherwise, if PCRE_PARTIAL_SOFT is set, matching continues
+by testing any other alternatives. Only if they all fail is PCRE_ERROR_PARTIAL
+returned (instead of PCRE_ERROR_NOMATCH). The portion of the string that
+was inspected when the partial match was found is set as the first matching
+string. There is a more detailed discussion in the
+.\" HREF

+documentation.
+.
+.SS "The string to be matched by \fBpcre_exec()\fP"
+.rs
+.sp
+The subject string is passed to \fBpcre_exec()\fP as a pointer in
+\fIsubject\fP, a length (in bytes) in \fIlength\fP, and a starting byte offset
+in \fIstartoffset\fP. In UTF-8 mode, the byte offset must point to the start of
+a UTF-8 character. Unlike the pattern string, the subject may contain binary
+zero bytes. When the starting offset is zero, the search for a match starts at
+the beginning of the subject, and this is by far the most common case.
+.P
+A non-zero starting offset is useful when searching for another match in the
+same subject by calling \fBpcre_exec()\fP again after a previous success.
+Setting \fIstartoffset\fP differs from just passing over a shortened string and
+setting PCRE_NOTBOL in the case of a pattern that begins with any kind of
+lookbehind. For example, consider the pattern
+.sp
+  \eBiss\eB
+.sp
+which finds occurrences of "iss" in the middle of words. (\eB matches only if
+the current position in the subject is not a word boundary.) When applied to
+the string "Mississipi" the first call to \fBpcre_exec()\fP finds the first
+occurrence. If \fBpcre_exec()\fP is called again with just the remainder of the
+subject, namely "issipi", it does not match, because \eB is always false at the
+start of the subject, which is deemed to be a word boundary. However, if
+\fBpcre_exec()\fP is passed the entire string again, but with \fIstartoffset\fP
+set to 4, it finds the second occurrence of "iss" because it is able to look
+behind the starting point to discover that it is preceded by a letter.
+.P
+If a non-zero starting offset is passed when the pattern is anchored, one
+attempt to match at the given offset is made. This can only succeed if the
+pattern does not require the match to be at the start of the subject.
+.
+.SS "How \fBpcre_exec()\fP returns captured substrings"
+.rs
+.sp
+In general, a pattern matches a certain portion of the subject, and in
+addition, further substrings from the subject may be picked out by parts of the
+pattern. Following the usage in Jeffrey Friedl's book, this is called
+"capturing" in what follows, and the phrase "capturing subpattern" is used for
+a fragment of a pattern that picks out a substring. PCRE supports several other
+kinds of parenthesized subpattern that do not cause substrings to be captured.
+.P
+Captured substrings are returned to the caller via a vector of integers whose
+address is passed in \fIovector\fP. The number of elements in the vector is
+passed in \fIovecsize\fP, which must be a non-negative number. \fBNote\fP: this
+argument is NOT the size of \fIovector\fP in bytes.
+.P
+The first two-thirds of the vector is used to pass back captured substrings,
+each substring using a pair of integers. The remaining third of the vector is
+used as workspace by \fBpcre_exec()\fP while matching capturing subpatterns,
+and is not available for passing back information. The number passed in
+\fIovecsize\fP should always be a multiple of three. If it is not, it is
+rounded down.
+.P
+When a match is successful, information about captured substrings is returned
+in pairs of integers, starting at the beginning of \fIovector\fP, and
+continuing up to two-thirds of its length at the most. The first element of
+each pair is set to the byte offset of the first character in a substring, and
+the second is set to the byte offset of the first character after the end of a
+substring. \fBNote\fP: these values are always byte offsets, even in UTF-8
+mode. They are not character counts.
+.P
+The first pair of integers, \fIovector[0]\fP and \fIovector[1]\fP, identify the
+portion of the subject string matched by the entire pattern. The next pair is
+used for the first capturing subpattern, and so on. The value returned by
+\fBpcre_exec()\fP is one more than the highest numbered pair that has been set.
+For example, if two substrings have been captured, the returned value is 3. If
+there are no capturing subpatterns, the return value from a successful match is
+1, indicating that just the first pair of offsets has been set.
+.P
+If a capturing subpattern is matched repeatedly, it is the last portion of the
+string that it matched that is returned.
+.P
+If the vector is too small to hold all the captured substring offsets, it is
+used as far as possible (up to two-thirds of its length), and the function
+returns a value of zero. If the substring offsets are not of interest,
+\fBpcre_exec()\fP may be called with \fIovector\fP passed as NULL and
+\fIovecsize\fP as zero. However, if the pattern contains back references and
+the \fIovector\fP is not big enough to remember the related substrings, PCRE
+has to get additional memory for use during matching. Thus it is usually
+advisable to supply an \fIovector\fP.
+.P
+The \fBpcre_fullinfo()\fP function can be used to find out how many capturing
+subpatterns there are in a compiled pattern. The smallest size for
+\fIovector\fP that will allow for \fIn\fP captured substrings, in addition to
+the offsets of the substring matched by the whole pattern, is (\fIn\fP+1)*3.
+.P
+It is possible for capturing subpattern number \fIn+1\fP to match some part of
+the subject when subpattern \fIn\fP has not been used at all. For example, if
+the string "abc" is matched against the pattern (a|(z))(bc) the return from the
+function is 4, and subpatterns 1 and 3 are matched, but 2 is not. When this
+happens, both values in the offset pairs corresponding to unused subpatterns
+are set to -1.
+.P
+Offset values that correspond to unused subpatterns at the end of the
+expression are also set to -1. For example, if the string "abc" is matched
+against the pattern (abc)(x(yz)?)? subpatterns 2 and 3 are not matched. The
+return from the function is 2, because the highest used capturing subpattern
+number is 1. However, you can refer to the offsets for the second and third
+capturing subpatterns if you wish (assuming the vector is large enough, of
+course).
+.P
+Some convenience functions are provided for extracting the captured substrings
+as separate strings. These are described below.

+.PP
+Captured substrings can be accessed directly by using the offsets returned by
+\fBpcre_exec()\fP in \fIovector\fP. For convenience, the functions
+\fBpcre_copy_substring()\fP, \fBpcre_get_substring()\fP, and
+\fBpcre_get_substring_list()\fP are provided for extracting captured substrings
+as new, separate, zero-terminated strings. These functions identify substrings
+by number. The next section describes functions for extracting named
+substrings.
+.P
+A substring that contains a binary zero is correctly extracted and has a
+further zero added on the end, but the result is not, of course, a C string.
+However, you can process such a string by referring to the length that is
+returned by \fBpcre_copy_substring()\fP and \fBpcre_get_substring()\fP.
+Unfortunately, the interface to \fBpcre_get_substring_list()\fP is not adequate
+for handling strings containing binary zeros, because the end of the final
+string is not independently indicated.
+.P
+The first three arguments are the same for all three of these functions:
+\fIsubject\fP is the subject string that has just been successfully matched,
+\fIovector\fP is a pointer to the vector of integer offsets that was passed to
+\fBpcre_exec()\fP, and \fIstringcount\fP is the number of substrings that were
+captured by the match, including the substring that matched the entire regular
+expression. This is the value returned by \fBpcre_exec()\fP if it is greater
+than zero. If \fBpcre_exec()\fP returned zero, indicating that it ran out of
+space in \fIovector\fP, the value passed as \fIstringcount\fP should be the
+number of elements in the vector divided by three.
+.P
+The functions \fBpcre_copy_substring()\fP and \fBpcre_get_substring()\fP
+extract a single substring, whose number is given as \fIstringnumber\fP. A
+value of zero extracts the substring that matched the entire pattern, whereas
+higher values extract the captured substrings. For \fBpcre_copy_substring()\fP,
+the string is placed in \fIbuffer\fP, whose length is given by
+\fIbuffersize\fP, while for \fBpcre_get_substring()\fP a new block of memory is
+obtained via \fBpcre_malloc\fP, and its address is returned via
+\fIstringptr\fP. The yield of the function is the length of the string, not
+including the terminating zero, or one of these error codes:
+.sp
+  PCRE_ERROR_NOMEMORY       (-6)
+.sp
+The buffer was too small for \fBpcre_copy_substring()\fP, or the attempt to get
+memory failed for \fBpcre_get_substring()\fP.
+.sp
+  PCRE_ERROR_NOSUBSTRING    (-7)
+.sp
+There is no substring whose number is \fIstringnumber\fP.
+.P
+The \fBpcre_get_substring_list()\fP function extracts all available substrings
+and builds a list of pointers to them. All this is done in a single block of
+memory that is obtained via \fBpcre_malloc\fP. The address of the memory block
+is returned via \fIlistptr\fP, which is also the start of the list of string
+pointers. The end of the list is marked by a NULL pointer. The yield of the
+function is zero if all went well, or the error code
+.sp
+  PCRE_ERROR_NOMEMORY       (-6)
+.sp
+if the attempt to get the memory block failed.
+.P
+When any of these functions encounter a substring that is unset, which can
+happen when capturing subpattern number \fIn+1\fP matches some part of the
+subject, but subpattern \fIn\fP has not been used at all, they return an empty
+string. This can be distinguished from a genuine zero-length substring by
+inspecting the appropriate offset in \fIovector\fP, which is negative for unset
+substrings.
+.P
+The two convenience functions \fBpcre_free_substring()\fP and
+\fBpcre_free_substring_list()\fP can be used to free the memory returned by
+a previous call of \fBpcre_get_substring()\fP or
+\fBpcre_get_substring_list()\fP, respectively. They do nothing more than call
+the function pointed to by \fBpcre_free\fP, which of course could be called
+directly from a C program. However, PCRE is used in some situations where it is
+linked via a special interface to another programming language that cannot use
+\fBpcre_free\fP directly; it is for these cases that the functions are
+provided.

+.P
+If you want to get full details of all captured substrings for a given name,

+\fBpcre_dfa_exec()\fP, it returns PCRE_ERROR_PARTIAL if the end of the subject
+is reached and there is still at least one matching possibility that requires
+additional characters. This happens even if some complete matches have also

+there have been no complete matches, but there is still at least one matching
+possibility. The portion of the string that was inspected when the longest
+partial match was found is set as the first matching string in both cases.
+.sp
+  PCRE_DFA_SHORTEST
+.sp
+Setting the PCRE_DFA_SHORTEST option causes the matching algorithm to stop as

+.TH PCREBUILD 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.
+.
+.SH "PCRE BUILD-TIME OPTIONS"
+.rs
+.sp
+This document describes the optional features of PCRE that can be selected when
+the library is compiled. It assumes use of the \fBconfigure\fP script, where
+the optional features are selected or deselected by providing options to
+\fBconfigure\fP before running the \fBmake\fP command. However, the same
+options can be selected in both Unix-like and non-Unix-like environments using
+the GUI facility of \fBcmake-gui\fP if you are using \fBCMake\fP instead of
+\fBconfigure\fP to build PCRE.
+.P
+There is a lot more information about building PCRE in non-Unix-like
+environments in the file called \fINON_UNIX_USE\fP, which is part of the PCRE
+distribution. You should consult this file as well as the \fIREADME\fP file if
+you are building in a non-Unix-like environment.
+.P
+The complete list of options for \fBconfigure\fP (which includes the standard
+ones such as the selection of the installation directory) can be obtained by
+running
+.sp
+  ./configure --help
+.sp
+The following sections include descriptions of options whose names begin with
+--enable or --disable. These settings specify changes to the defaults for the
+\fBconfigure\fP command. Because of the way that \fBconfigure\fP works,
+--enable and --disable always come in pairs, so the complementary option always
+exists as well, but as it specifies the default, it is not described.
+.
+.
+.SH "C++ SUPPORT"
+.rs
+.sp
+By default, the \fBconfigure\fP script will search for a C++ compiler and C++
+header files. If it finds them, it automatically builds the C++ wrapper library
+for PCRE. You can disable this by adding
+.sp
+  --disable-cpp
+.sp
+to the \fBconfigure\fP command.
+.
+.
+.SH "UTF-8 SUPPORT"
+.rs
+.sp
+To build PCRE with support for UTF-8 Unicode character strings, add
+.sp
+  --enable-utf8
+.sp
+to the \fBconfigure\fP command. Of itself, this does not make PCRE treat
+strings as UTF-8. As well as compiling PCRE with this option, you also have
+have to set the PCRE_UTF8 option when you call the \fBpcre_compile()\fP
+or \fBpcre_compile2()\fP functions.
+.P
+If you set --enable-utf8 when compiling in an EBCDIC environment, PCRE expects
+its input to be either ASCII or UTF-8 (depending on the runtime option). It is
+not possible to support both EBCDIC and UTF-8 codes in the same version of the
+library. Consequently, --enable-utf8 and --enable-ebcdic are mutually
+exclusive.
+.
+.
+.SH "UNICODE CHARACTER PROPERTY SUPPORT"
+.rs
+.sp
+UTF-8 support allows PCRE to process character values greater than 255 in the
+strings that it handles. On its own, however, it does not provide any
+facilities for accessing the properties of such characters. If you want to be
+able to use the pattern escapes \eP, \ep, and \eX, which refer to Unicode
+character properties, you must add
+.sp
+  --enable-unicode-properties
+.sp
+to the \fBconfigure\fP command. This implies UTF-8 support, even if you have
+not explicitly requested it.
+.P
+Including Unicode property support adds around 30K of tables to the PCRE
+library. Only the general category properties such as \fILu\fP and \fINd\fP are
+supported. Details are given in the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+documentation.
+.
+.
+.SH "CODE VALUE OF NEWLINE"
+.rs
+.sp
+By default, PCRE interprets the linefeed (LF) character as indicating the end
+of a line. This is the normal newline character on Unix-like systems. You can
+compile PCRE to use carriage return (CR) instead, by adding
+.sp
+  --enable-newline-is-cr
+.sp
+to the \fBconfigure\fP command. There is also a --enable-newline-is-lf option,
+which explicitly specifies linefeed as the newline character.
+.sp
+Alternatively, you can specify that line endings are to be indicated by the two
+character sequence CRLF. If you want this, add
+.sp
+  --enable-newline-is-crlf
+.sp
+to the \fBconfigure\fP command. There is a fourth option, specified by
+.sp
+  --enable-newline-is-anycrlf
+.sp
+which causes PCRE to recognize any of the three sequences CR, LF, or CRLF as
+indicating a line ending. Finally, a fifth option, specified by
+.sp
+  --enable-newline-is-any
+.sp
+causes PCRE to recognize any Unicode newline sequence.
+.P
+Whatever line ending convention is selected when PCRE is built can be
+overridden when the library functions are called. At build time it is
+conventional to use the standard for your operating system.
+.
+.
+.SH "WHAT \eR MATCHES"
+.rs
+.sp
+By default, the sequence \eR in a pattern matches any Unicode newline sequence,
+whatever has been selected as the line ending sequence. If you specify
+.sp
+  --enable-bsr-anycrlf
+.sp
+the default is changed so that \eR matches only CR, LF, or CRLF. Whatever is
+selected when PCRE is built can be overridden when the library functions are
+called.
+.
+.
+.SH "BUILDING SHARED AND STATIC LIBRARIES"
+.rs
+.sp
+The PCRE building process uses \fBlibtool\fP to build both shared and static
+Unix libraries by default. You can suppress one of these by adding one of
+.sp
+  --disable-shared
+  --disable-static
+.sp
+to the \fBconfigure\fP command, as required.
+.
+.
+.SH "POSIX MALLOC USAGE"
+.rs
+.sp
+When PCRE is called through the POSIX interface (see the
+.\" HREF
+\fBpcreposix\fP
+.\"
+documentation), additional working storage is required for holding the pointers
+to capturing substrings, because PCRE requires three integers per substring,
+whereas the POSIX interface provides only two. If the number of expected
+substrings is small, the wrapper function uses space on the stack, because this
+is faster than using \fBmalloc()\fP for each call. The default threshold above
+which the stack is no longer used is 10; it can be changed by adding a setting
+such as
+.sp
+  --with-posix-malloc-threshold=20
+.sp
+to the \fBconfigure\fP command.
+.
+.
+.SH "HANDLING VERY LARGE PATTERNS"
+.rs
+.sp
+Within a compiled pattern, offset values are used to point from one part to
+another (for example, from an opening parenthesis to an alternation
+metacharacter). By default, two-byte values are used for these offsets, leading
+to a maximum size for a compiled pattern of around 64K. This is sufficient to
+handle all but the most gigantic patterns. Nevertheless, some people do want to
+process truyl enormous patterns, so it is possible to compile PCRE to use
+three-byte or four-byte offsets by adding a setting such as
+.sp
+  --with-link-size=3
+.sp
+to the \fBconfigure\fP command. The value given must be 2, 3, or 4. Using
+longer offsets slows down the operation of PCRE because it has to load
+additional bytes when handling them.
+.
+.
+.SH "AVOIDING EXCESSIVE STACK USAGE"
+.rs
+.sp
+When matching with the \fBpcre_exec()\fP function, PCRE implements backtracking
+by making recursive calls to an internal function called \fBmatch()\fP. In
+environments where the size of the stack is limited, this can severely limit
+PCRE's operation. (The Unix environment does not usually suffer from this
+problem, but it may sometimes be necessary to increase the maximum stack size.
+There is a discussion in the
+.\" HREF
+\fBpcrestack\fP
+.\"
+documentation.) An alternative approach to recursion that uses memory from the
+heap to remember data, instead of using recursive function calls, has been
+implemented to work round the problem of limited stack size. If you want to
+build a version of PCRE that works this way, add
+.sp
+  --disable-stack-for-recursion
+.sp
+to the \fBconfigure\fP command. With this configuration, PCRE will use the
+\fBpcre_stack_malloc\fP and \fBpcre_stack_free\fP variables to call memory
+management functions. By default these point to \fBmalloc()\fP and
+\fBfree()\fP, but you can replace the pointers so that your own functions are
+used instead.
+.P
+Separate functions are provided rather than using \fBpcre_malloc\fP and
+\fBpcre_free\fP because the usage is very predictable: the block sizes
+requested are always the same, and the blocks are always freed in reverse
+order. A calling program might be able to implement optimized functions that
+perform better than \fBmalloc()\fP and \fBfree()\fP. PCRE runs noticeably more
+slowly when built in this way. This option affects only the \fBpcre_exec()\fP
+function; it is not relevant for \fBpcre_dfa_exec()\fP.
+.
+.
+.SH "LIMITING PCRE RESOURCE USAGE"
+.rs
+.sp
+Internally, PCRE has a function called \fBmatch()\fP, which it calls repeatedly
+(sometimes recursively) when matching a pattern with the \fBpcre_exec()\fP
+function. By controlling the maximum number of times this function may be
+called during a single matching operation, a limit can be placed on the
+resources used by a single call to \fBpcre_exec()\fP. The limit can be changed
+at run time, as described in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation. The default is 10 million, but this can be changed by adding a
+setting such as
+.sp
+  --with-match-limit=500000
+.sp
+to the \fBconfigure\fP command. This setting has no effect on the
+\fBpcre_dfa_exec()\fP matching function.
+.P
+In some environments it is desirable to limit the depth of recursive calls of
+\fBmatch()\fP more strictly than the total number of calls, in order to
+restrict the maximum amount of stack (or heap, if --disable-stack-for-recursion
+is specified) that is used. A second limit controls this; it defaults to the
+value that is set for --with-match-limit, which imposes no additional
+constraints. However, you can set a lower limit by adding, for example,
+.sp
+  --with-match-limit-recursion=10000
+.sp
+to the \fBconfigure\fP command. This value can also be overridden at run time.
+.
+.
+.SH "CREATING CHARACTER TABLES AT BUILD TIME"
+.rs
+.sp
+PCRE uses fixed tables for processing characters whose code values are less
+than 256. By default, PCRE is built with a set of tables that are distributed
+in the file \fIpcre_chartables.c.dist\fP. These tables are for ASCII codes
+only. If you add
+.sp
+  --enable-rebuild-chartables
+.sp
+to the \fBconfigure\fP command, the distributed tables are no longer used.
+Instead, a program called \fBdftables\fP is compiled and run. This outputs the
+source for new set of tables, created in the default locale of your C runtime
+system. (This method of replacing the tables does not work if you are cross
+compiling, because \fBdftables\fP is run on the local host. If you need to
+create alternative tables when cross compiling, you will have to do so "by
+hand".)
+.
+.
+.SH "USING EBCDIC CODE"
+.rs
+.sp
+PCRE assumes by default that it will run in an environment where the character
+code is ASCII (or Unicode, which is a superset of ASCII). This is the case for
+most computer operating systems. PCRE can, however, be compiled to run in an
+EBCDIC environment by adding
+.sp
+  --enable-ebcdic
+.sp
+to the \fBconfigure\fP command. This setting implies
+--enable-rebuild-chartables. You should only use it if you know that you are in
+an EBCDIC environment (for example, an IBM mainframe operating system). The
+--enable-ebcdic option is incompatible with --enable-utf8.
+.
+.
+.SH "PCREGREP OPTIONS FOR COMPRESSED FILE SUPPORT"
+.rs
+.sp
+By default, \fBpcregrep\fP reads all files as plain text. You can build it so
+that it recognizes files whose names end in \fB.gz\fP or \fB.bz2\fP, and reads
+them with \fBlibz\fP or \fBlibbz2\fP, respectively, by adding one or both of
+.sp
+  --enable-pcregrep-libz
+  --enable-pcregrep-libbz2
+.sp
+to the \fBconfigure\fP command. These options naturally require that the
+relevant libraries are installed on your system. Configuration will fail if
+they are not.
+.
+.
+.SH "PCRETEST OPTION FOR LIBREADLINE SUPPORT"
+.rs
+.sp
+If you add
+.sp
+  --enable-pcretest-libreadline
+.sp
+to the \fBconfigure\fP command, \fBpcretest\fP is linked with the
+\fBlibreadline\fP library, and when its input is from a terminal, it reads it
+using the \fBreadline()\fP function. This provides line-editing and history
+facilities. Note that \fBlibreadline\fP is GPL-licensed, so if you distribute a
+binary of \fBpcretest\fP linked in this way, there may be licensing issues.
+.P
+Setting this option causes the \fB-lreadline\fP option to be added to the
+\fBpcretest\fP build. In many operating environments with a sytem-installed
+\fBlibreadline\fP this is sufficient. However, in some environments (e.g.
+if an unmodified distribution version of readline is in use), some extra
+configuration may be necessary. The INSTALL file for \fBlibreadline\fP says
+this:
+.sp
+  "Readline uses the termcap functions, but does not link with the
+  termcap or curses library itself, allowing applications which link
+  with readline the to choose an appropriate library."
+.sp
+If your environment has not been set up so that an appropriate library is
+automatically included, you may need to add something like
+.sp
+  LIBS="-ncurses"
+.sp
+immediately before the \fBconfigure\fP command.

+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH "PCRE CALLOUTS"
+.rs
+.sp
+.B int (*pcre_callout)(pcre_callout_block *);
+.PP
+PCRE provides a feature called "callout", which is a means of temporarily
+passing control to the caller of PCRE in the middle of pattern matching. The
+caller of PCRE provides an external function by putting its entry point in the
+global variable \fIpcre_callout\fP. By default, this variable contains NULL,
+which disables all calling out.
+.P
+Within a regular expression, (?C) indicates the points at which the external
+function is to be called. Different callout points can be identified by putting
+a number less than 256 after the letter C. The default value is zero.
+For example, this pattern has two callout points:
+.sp
+  (?C1)abc(?C2)def
+.sp
+If the PCRE_AUTO_CALLOUT option bit is set when \fBpcre_compile()\fP or
+\fBpcre_compile2()\fP is called, PCRE automatically inserts callouts, all with
+number 255, before each item in the pattern. For example, if PCRE_AUTO_CALLOUT
+is used with the pattern
+.sp
+  A(\ed{2}|--)
+.sp
+it is processed as if it were
+.sp
+(?C255)A(?C255)((?C255)\ed{2}(?C255)|(?C255)-(?C255)-(?C255))(?C255)
+.sp
+Notice that there is a callout before and after each parenthesis and
+alternation bar. Automatic callouts can be used for tracking the progress of
+pattern matching. The
+.\" HREF
+\fBpcretest\fP
+.\"
+command has an option that sets automatic callouts; when it is used, the output
+indicates how the pattern is matched. This is useful information when you are
+trying to optimize the performance of a particular pattern.
+.
+.
+.SH "MISSING CALLOUTS"
+.rs
+.sp
+You should be aware that, because of optimizations in the way PCRE matches
+patterns by default, callouts sometimes do not happen. For example, if the
+pattern is
+.sp
+  ab(?C4)cd
+.sp
+PCRE knows that any matching string must contain the letter "d". If the subject
+string is "abyz", the lack of "d" means that matching doesn't ever start, and
+the callout is never reached. However, with "abyd", though the result is still
+no match, the callout is obeyed.
+.P
+If the pattern is studied, PCRE knows the minimum length of a matching string,
+and will immediately give a "no match" return without actually running a match
+if the subject is not long enough, or, for unanchored patterns, if it has
+been scanned far enough.
+.P
+You can disable these optimizations by passing the PCRE_NO_START_OPTIMIZE
+option to \fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP. This slows down the
+matching process, but does ensure that callouts such as the example above are
+obeyed.
+.
+.
+.SH "THE CALLOUT INTERFACE"
+.rs
+.sp
+During matching, when PCRE reaches a callout point, the external function
+defined by \fIpcre_callout\fP is called (if it is set). This applies to both
+the \fBpcre_exec()\fP and the \fBpcre_dfa_exec()\fP matching functions. The
+only argument to the callout function is a pointer to a \fBpcre_callout\fP
+block. This structure contains the following fields:
+.sp
+  int          \fIversion\fP;
+  int          \fIcallout_number\fP;
+  int         *\fIoffset_vector\fP;
+  const char  *\fIsubject\fP;
+  int          \fIsubject_length\fP;
+  int          \fIstart_match\fP;
+  int          \fIcurrent_position\fP;
+  int          \fIcapture_top\fP;
+  int          \fIcapture_last\fP;
+  void        *\fIcallout_data\fP;
+  int          \fIpattern_position\fP;
+  int          \fInext_item_length\fP;
+.sp
+The \fIversion\fP field is an integer containing the version number of the
+block format. The initial version was 0; the current version is 1. The version
+number will change again in future if additional fields are added, but the
+intention is never to remove any of the existing fields.
+.P
+The \fIcallout_number\fP field contains the number of the callout, as compiled
+into the pattern (that is, the number after ?C for manual callouts, and 255 for
+automatically generated callouts).
+.P
+The \fIoffset_vector\fP field is a pointer to the vector of offsets that was
+passed by the caller to \fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP. When
+\fBpcre_exec()\fP is used, the contents can be inspected in order to extract
+substrings that have been matched so far, in the same way as for extracting
+substrings after a match has completed. For \fBpcre_dfa_exec()\fP this field is
+not useful.
+.P
+The \fIsubject\fP and \fIsubject_length\fP fields contain copies of the values
+that were passed to \fBpcre_exec()\fP.
+.P
+The \fIstart_match\fP field normally contains the offset within the subject at
+which the current match attempt started. However, if the escape sequence \eK
+has been encountered, this value is changed to reflect the modified starting
+point. If the pattern is not anchored, the callout function may be called
+several times from the same point in the pattern for different starting points
+in the subject.
+.P
+The \fIcurrent_position\fP field contains the offset within the subject of the
+current match pointer.
+.P
+When the \fBpcre_exec()\fP function is used, the \fIcapture_top\fP field
+contains one more than the number of the highest numbered captured substring so
+far. If no substrings have been captured, the value of \fIcapture_top\fP is
+one. This is always the case when \fBpcre_dfa_exec()\fP is used, because it
+does not support captured substrings.
+.P
+The \fIcapture_last\fP field contains the number of the most recently captured
+substring. If no substrings have been captured, its value is -1. This is always
+the case when \fBpcre_dfa_exec()\fP is used.
+.P
+The \fIcallout_data\fP field contains a value that is passed to
+\fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP specifically so that it can be
+passed back in callouts. It is passed in the \fIpcre_callout\fP field of the
+\fBpcre_extra\fP data structure. If no such data was passed, the value of
+\fIcallout_data\fP in a \fBpcre_callout\fP block is NULL. There is a
+description of the \fBpcre_extra\fP structure in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation.
+.P
+The \fIpattern_position\fP field is present from version 1 of the
+\fIpcre_callout\fP structure. It contains the offset to the next item to be
+matched in the pattern string.
+.P
+The \fInext_item_length\fP field is present from version 1 of the
+\fIpcre_callout\fP structure. It contains the length of the next item to be
+matched in the pattern string. When the callout immediately precedes an
+alternation bar, a closing parenthesis, or the end of the pattern, the length
+is zero. When the callout precedes an opening parenthesis, the length is that
+of the entire subpattern.
+.P
+The \fIpattern_position\fP and \fInext_item_length\fP fields are intended to
+help in distinguishing between different automatic callouts, which all have the
+same callout number. However, they are set for all callouts.
+.
+.
+.SH "RETURN VALUES"
+.rs
+.sp
+The external callout function returns an integer to PCRE. If the value is zero,
+matching proceeds as normal. If the value is greater than zero, matching fails
+at the current point, but the testing of other matching possibilities goes
+ahead, just as if a lookahead assertion had failed. If the value is less than
+zero, the match is abandoned, and \fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP
+returns the negative value.
+.P
+Negative values should normally be chosen from the set of PCRE_ERROR_xxx
+values. In particular, PCRE_ERROR_NOMATCH forces a standard "no match" failure.
+The error number PCRE_ERROR_CALLOUT is reserved for use by callout functions;
+it will never be used by PCRE itself.

+.TH PCRECOMPAT 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH "DIFFERENCES BETWEEN PCRE AND PERL"
+.rs
+.sp
+This document describes the differences in the ways that PCRE and Perl handle
+regular expressions. The differences described here are with respect to Perl
+5.10.
+.P
+1. PCRE has only a subset of Perl's UTF-8 and Unicode support. Details of what
+it does have are given in the
+.\" HTML 
+.\" 
+section on UTF-8 support
+.\"
+in the main
+.\" HREF
+\fBpcre\fP
+.\"
+page.
+.P
+2. PCRE does not allow repeat quantifiers on lookahead assertions. Perl permits
+them, but they do not mean what you might think. For example, (?!a){3} does
+not assert that the next three characters are not "a". It just asserts that the
+next character is not "a" three times.
+.P
+3. Capturing subpatterns that occur inside negative lookahead assertions are
+counted, but their entries in the offsets vector are never set. Perl sets its
+numerical variables from any such patterns that are matched before the
+assertion fails to match something (thereby succeeding), but only if the
+negative lookahead assertion contains just one branch.
+.P
+4. Though binary zero characters are supported in the subject string, they are
+not allowed in a pattern string because it is passed as a normal C string,
+terminated by zero. The escape sequence \e0 can be used in the pattern to
+represent a binary zero.
+.P
+5. The following Perl escape sequences are not supported: \el, \eu, \eL,
+\eU, and \eN. In fact these are implemented by Perl's general string-handling
+and are not part of its pattern matching engine. If any of these are
+encountered by PCRE, an error is generated.
+.P
+6. The Perl escape sequences \ep, \eP, and \eX are supported only if PCRE is
+built with Unicode character property support. The properties that can be
+tested with \ep and \eP are limited to the general category properties such as
+Lu and Nd, script names such as Greek or Han, and the derived properties Any
+and L&. PCRE does support the Cs (surrogate) property, which Perl does not; the
+Perl documentation says "Because Perl hides the need for the user to understand
+the internal representation of Unicode characters, there is no need to
+implement the somewhat messy concept of surrogates."
+.P
+7. PCRE does support the \eQ...\eE escape for quoting substrings. Characters in
+between are treated as literals. This is slightly different from Perl in that $
+and @ are also handled as literals inside the quotes. In Perl, they cause
+variable interpolation (but of course PCRE does not have variables). Note the
+following examples:
+.sp
+    Pattern            PCRE matches      Perl matches
+.sp
+.\" JOIN
+    \eQabc$xyz\eE        abc$xyz           abc followed by the
+                                           contents of $xyz
+    \eQabc\e$xyz\eE       abc\e$xyz          abc\e$xyz
+    \eQabc\eE\e$\eQxyz\eE   abc$xyz           abc$xyz
+.sp
+The \eQ...\eE sequence is recognized both inside and outside character classes.
+.P
+8. Fairly obviously, PCRE does not support the (?{code}) and (??{code})
+constructions. However, there is support for recursive patterns. This is not
+available in Perl 5.8, but it is in Perl 5.10. Also, the PCRE "callout"
+feature allows an external function to be called during pattern matching. See
+the
+.\" HREF
+\fBpcrecallout\fP
+.\"
+documentation for details.
+.P
+9. Subpatterns that are called recursively or as "subroutines" are always
+treated as atomic groups in PCRE. This is like Python, but unlike Perl. There
+is a discussion of an example that explains this in more detail in the
+.\" HTML 
+.\" 
+section on recursion differences from Perl
+.\"
+in the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+page.
+.P
+10. There are some differences that are concerned with the settings of captured
+strings when part of a pattern is repeated. For example, matching "aba" against
+the pattern /^(a(b)?)+$/ in Perl leaves $2 unset, but in PCRE it is set to "b".
+.P
+11. PCRE does support Perl 5.10's backtracking verbs (*ACCEPT), (*FAIL), (*F),
+(*COMMIT), (*PRUNE), (*SKIP), and (*THEN), but only in the forms without an
+argument. PCRE does not support (*MARK).
+.P
+12. PCRE's handling of duplicate subpattern numbers and duplicate subpattern
+names is not as general as Perl's. This is a consequence of the fact the PCRE
+works internally just with numbers, using an external table to translate
+between numbers and names. In particular, a pattern such as (?|(?A)|(?
+.
+.SH DESCRIPTION
+.rs
+.sp
+The C++ wrapper for PCRE was provided by Google Inc. Some additional
+functionality was added by Giuseppe Maxia. This brief man page was constructed
+from the notes in the \fIpcrecpp.h\fP file, which should be consulted for
+further details.
+.
+.
+.SH "MATCHING INTERFACE"
+.rs
+.sp
+The "FullMatch" operation checks that supplied text matches a supplied pattern
+exactly. If pointer arguments are supplied, it copies matched sub-strings that
+match sub-patterns into them.
+.sp
+  Example: successful match
+     pcrecpp::RE re("h.*o");
+     re.FullMatch("hello");
+.sp
+  Example: unsuccessful match (requires full match):
+     pcrecpp::RE re("e");
+     !re.FullMatch("hello");
+.sp
+  Example: creating a temporary RE object:
+     pcrecpp::RE("h.*o").FullMatch("hello");
+.sp
+You can pass in a "const char*" or a "string" for "text". The examples below
+tend to use a const char*. You can, as in the different examples above, store
+the RE object explicitly in a variable or use a temporary RE object. The
+examples below use one mode or the other arbitrarily. Either could correctly be
+used for any of these examples.
+.P
+You must supply extra pointer arguments to extract matched subpieces.
+.sp
+  Example: extracts "ruby" into "s" and 1234 into "i"
+     int i;
+     string s;
+     pcrecpp::RE re("(\e\ew+):(\e\ed+)");
+     re.FullMatch("ruby:1234", &s, &i);
+.sp
+  Example: does not try to extract any extra sub-patterns
+     re.FullMatch("ruby:1234", &s);
+.sp
+  Example: does not try to extract into NULL
+     re.FullMatch("ruby:1234", NULL, &i);
+.sp
+  Example: integer overflow causes failure
+     !re.FullMatch("ruby:1234567891234", NULL, &i);
+.sp
+  Example: fails because there aren't enough sub-patterns:
+     !pcrecpp::RE("\e\ew+:\e\ed+").FullMatch("ruby:1234", &s);
+.sp
+  Example: fails because string cannot be stored in integer
+     !pcrecpp::RE("(.*)").FullMatch("ruby", &i);
+.sp
+The provided pointer arguments can be pointers to any scalar numeric
+type, or one of:
+.sp
+   string        (matched piece is copied to string)
+   StringPiece   (StringPiece is mutated to point to matched piece)
+   T             (where "bool T::ParseFrom(const char*, int)" exists)
+   NULL          (the corresponding matched sub-pattern is not copied)
+.sp
+The function returns true iff all of the following conditions are satisfied:
+.sp
+  a. "text" matches "pattern" exactly;
+.sp
+  b. The number of matched sub-patterns is >= number of supplied
+     pointers;
+.sp
+  c. The "i"th argument has a suitable type for holding the
+     string captured as the "i"th sub-pattern. If you pass in
+     void * NULL for the "i"th argument, or a non-void * NULL
+     of the correct type, or pass fewer arguments than the
+     number of sub-patterns, "i"th captured sub-pattern is
+     ignored.
+.sp
+CAVEAT: An optional sub-pattern that does not exist in the matched
+string is assigned the empty string. Therefore, the following will
+return false (because the empty string is not a valid number):
+.sp
+   int number;
+   pcrecpp::RE::FullMatch("abc", "[a-z]+(\e\ed+)?", &number);
+.sp
+The matching interface supports at most 16 arguments per call.
+If you need more, consider using the more general interface
+\fBpcrecpp::RE::DoMatch\fP. See \fBpcrecpp.h\fP for the signature for
+\fBDoMatch\fP.
+.P
+NOTE: Do not use \fBno_arg\fP, which is used internally to mark the end of a
+list of optional arguments, as a placeholder for missing arguments, as this can
+lead to segfaults.
+.
+.
+.SH "QUOTING METACHARACTERS"
+.rs
+.sp
+You can use the "QuoteMeta" operation to insert backslashes before all
+potentially meaningful characters in a string. The returned string, used as a
+regular expression, will exactly match the original string.
+.sp
+  Example:
+     string quoted = RE::QuoteMeta(unquoted);
+.sp
+Note that it's legal to escape a character even if it has no special meaning in
+a regular expression -- so this function does that. (This also makes it
+identical to the perl function of the same name; see "perldoc -f quotemeta".)
+For example, "1.5-2.0?" becomes "1\e.5\e-2\e.0\e?".
+.
+.SH "PARTIAL MATCHES"
+.rs
+.sp
+You can use the "PartialMatch" operation when you want the pattern
+to match any substring of the text.
+.sp
+  Example: simple search for a string:
+     pcrecpp::RE("ell").PartialMatch("hello");
+.sp
+  Example: find first number in a string:
+     int number;
+     pcrecpp::RE re("(\e\ed+)");
+     re.PartialMatch("x*100 + 20", &number);
+     assert(number == 100);
+.
+.
+.SH "UTF-8 AND THE MATCHING INTERFACE"
+.rs
+.sp
+By default, pattern and text are plain text, one byte per character. The UTF8
+flag, passed to the constructor, causes both pattern and string to be treated
+as UTF-8 text, still a byte stream but potentially multiple bytes per
+character. In practice, the text is likelier to be UTF-8 than the pattern, but
+the match returned may depend on the UTF8 flag, so always use it when matching
+UTF8 text. For example, "." will match one byte normally but with UTF8 set may
+match up to three bytes of a multi-byte character.
+.sp
+  Example:
+     pcrecpp::RE_Options options;
+     options.set_utf8();
+     pcrecpp::RE re(utf8_pattern, options);
+     re.FullMatch(utf8_string);
+.sp
+  Example: using the convenience function UTF8():
+     pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8());
+     re.FullMatch(utf8_string);
+.sp
+NOTE: The UTF8 flag is ignored if pcre was not configured with the
+      --enable-utf8 flag.
+.
+.
+.SH "PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE"
+.rs
+.sp
+PCRE defines some modifiers to change the behavior of the regular expression
+engine. The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle to
+pass such modifiers to a RE class. Currently, the following modifiers are
+supported:
+.sp
+   modifier              description               Perl corresponding
+.sp
+   PCRE_CASELESS         case insensitive match      /i
+   PCRE_MULTILINE        multiple lines match        /m
+   PCRE_DOTALL           dot matches newlines        /s
+   PCRE_DOLLAR_ENDONLY   $ matches only at end       N/A
+   PCRE_EXTRA            strict escape parsing       N/A
+   PCRE_EXTENDED         ignore whitespaces          /x
+   PCRE_UTF8             handles UTF8 chars          built-in
+   PCRE_UNGREEDY         reverses * and *?           N/A
+   PCRE_NO_AUTO_CAPTURE  disables capturing parens   N/A (*)
+.sp
+(*) Both Perl and PCRE allow non capturing parentheses by means of the
+"?:" modifier within the pattern itself. e.g. (?:ab|cd) does not
+capture, while (ab|cd) does.
+.P
+For a full account on how each modifier works, please check the
+PCRE API reference page.
+.P
+For each modifier, there are two member functions whose name is made
+out of the modifier in lowercase, without the "PCRE_" prefix. For
+instance, PCRE_CASELESS is handled by
+.sp
+  bool caseless()
+.sp
+which returns true if the modifier is set, and
+.sp
+  RE_Options & set_caseless(bool)
+.sp
+which sets or unsets the modifier. Moreover, PCRE_EXTRA_MATCH_LIMIT can be
+accessed through the \fBset_match_limit()\fR and \fBmatch_limit()\fR member
+functions. Setting \fImatch_limit\fR to a non-zero value will limit the
+execution of pcre to keep it from doing bad things like blowing the stack or
+taking an eternity to return a result. A value of 5000 is good enough to stop
+stack blowup in a 2MB thread stack. Setting \fImatch_limit\fR to zero disables
+match limiting. Alternatively, you can call \fBmatch_limit_recursion()\fP
+which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much PCRE
+recurses. \fBmatch_limit()\fP limits the number of matches PCRE does;
+\fBmatch_limit_recursion()\fP limits the depth of internal recursion, and
+therefore the amount of stack that is used.
+.P
+Normally, to pass one or more modifiers to a RE class, you declare
+a \fIRE_Options\fR object, set the appropriate options, and pass this
+object to a RE constructor. Example:
+.sp
+   RE_options opt;
+   opt.set_caseless(true);
+   if (RE("HELLO", opt).PartialMatch("hello world")) ...
+.sp
+RE_options has two constructors. The default constructor takes no arguments and
+creates a set of flags that are off by default. The optional parameter
+\fIoption_flags\fR is to facilitate transfer of legacy code from C programs.
+This lets you do
+.sp
+   RE(pattern,
+     RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str);
+.sp
+However, new code is better off doing
+.sp
+   RE(pattern,
+     RE_Options().set_caseless(true).set_multiline(true))
+       .PartialMatch(str);
+.sp
+If you are going to pass one of the most used modifiers, there are some
+convenience functions that return a RE_Options class with the
+appropriate modifier already set: \fBCASELESS()\fR, \fBUTF8()\fR,
+\fBMULTILINE()\fR, \fBDOTALL\fR(), and \fBEXTENDED()\fR.
+.P
+If you need to set several options at once, and you don't want to go through
+the pains of declaring a RE_Options object and setting several options, there
+is a parallel method that give you such ability on the fly. You can concatenate
+several \fBset_xxxxx()\fR member functions, since each of them returns a
+reference to its class object. For example, to pass PCRE_CASELESS,
+PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one statement, you may write:
+.sp
+   RE(" ^ xyz \e\es+ .* blah$",
+     RE_Options()
+       .set_caseless(true)
+       .set_extended(true)
+       .set_multiline(true)).PartialMatch(sometext);
+.sp
+.
+.
+.SH "SCANNING TEXT INCREMENTALLY"
+.rs
+.sp
+The "Consume" operation may be useful if you want to repeatedly
+match regular expressions at the front of a string and skip over
+them as they match. This requires use of the "StringPiece" type,
+which represents a sub-range of a real string. Like RE, StringPiece
+is defined in the pcrecpp namespace.
+.sp
+  Example: read lines of the form "var = value" from a string.
+     string contents = ...;                 // Fill string somehow
+     pcrecpp::StringPiece input(contents);  // Wrap in a StringPiece
+
+     string var;
+     int value;
+     pcrecpp::RE re("(\e\ew+) = (\e\ed+)\en");
+     while (re.Consume(&input, &var, &value)) {
+       ...;
+     }
+.sp
+Each successful call to "Consume" will set "var/value", and also
+advance "input" so it points past the matched text.
+.P
+The "FindAndConsume" operation is similar to "Consume" but does not
+anchor your match at the beginning of the string. For example, you
+could extract all words from a string by repeatedly calling
+.sp
+  pcrecpp::RE("(\e\ew+)").FindAndConsume(&input, &word)
+.
+.
+.SH "PARSING HEX/OCTAL/C-RADIX NUMBERS"
+.rs
+.sp
+By default, if you pass a pointer to a numeric value, the
+corresponding text is interpreted as a base-10 number. You can
+instead wrap the pointer with a call to one of the operators Hex(),
+Octal(), or CRadix() to interpret the text in another base. The
+CRadix operator interprets C-style "0" (base-8) and "0x" (base-16)
+prefixes, but defaults to base-10.
+.sp
+  Example:
+    int a, b, c, d;
+    pcrecpp::RE re("(.*) (.*) (.*) (.*)");
+    re.FullMatch("100 40 0100 0x40",
+                 pcrecpp::Octal(&a), pcrecpp::Hex(&b),
+                 pcrecpp::CRadix(&c), pcrecpp::CRadix(&d));
+.sp
+will leave 64 in a, b, c, and d.
+.
+.
+.SH "REPLACING PARTS OF STRINGS"
+.rs
+.sp
+You can replace the first match of "pattern" in "str" with "rewrite".
+Within "rewrite", backslash-escaped digits (\e1 to \e9) can be
+used to insert text matching corresponding parenthesized group
+from the pattern. \e0 in "rewrite" refers to the entire matching
+text. For example:
+.sp
+  string s = "yabba dabba doo";
+  pcrecpp::RE("b+").Replace("d", &s);
+.sp
+will leave "s" containing "yada dabba doo". The result is true if the pattern
+matches and a replacement occurs, false otherwise.
+.P
+\fBGlobalReplace\fP is like \fBReplace\fP except that it replaces all
+occurrences of the pattern in the string with the rewrite. Replacements are
+not subject to re-matching. For example:
+.sp
+  string s = "yabba dabba doo";
+  pcrecpp::RE("b+").GlobalReplace("d", &s);
+.sp
+will leave "s" containing "yada dada doo". It returns the number of
+replacements made.
+.P
+\fBExtract\fP is like \fBReplace\fP, except that if the pattern matches,
+"rewrite" is copied into "out" (an additional argument) with substitutions.
+The non-matching portions of "text" are ignored. Returns true iff a match
+occurred and the extraction happened successfully;  if no match occurs, the
+string is left unaffected.

+.SH NAME
+pcregrep - a grep with Perl-compatible regular expressions.
+.SH SYNOPSIS
+.B pcregrep [options] [long options] [pattern] [path1 path2 ...]
+.
+.SH DESCRIPTION
+.rs
+.sp
+\fBpcregrep\fP searches files for character patterns, in the same way as other
+grep commands do, but it uses the PCRE regular expression library to support
+patterns that are compatible with the regular expressions of Perl 5. See
+.\" HREF
+\fBpcrepattern\fP(3)
+.\"
+for a full description of syntax and semantics of the regular expressions
+that PCRE supports.
+.P
+Patterns, whether supplied on the command line or in a separate file, are given
+without delimiters. For example:
+.sp
+  pcregrep Thursday /etc/motd
+.sp
+If you attempt to use delimiters (for example, by surrounding a pattern with
+slashes, as is common in Perl scripts), they are interpreted as part of the
+pattern. Quotes can of course be used to delimit patterns on the command line
+because they are interpreted by the shell, and indeed they are required if a
+pattern contains white space or shell metacharacters.
+.P
+The first argument that follows any option settings is treated as the single
+pattern to be matched when neither \fB-e\fP nor \fB-f\fP is present.
+Conversely, when one or both of these options are used to specify patterns, all
+arguments are treated as path names. At least one of \fB-e\fP, \fB-f\fP, or an
+argument pattern must be provided.
+.P
+If no files are specified, \fBpcregrep\fP reads the standard input. The
+standard input can also be referenced by a name consisting of a single hyphen.
+For example:
+.sp
+  pcregrep some-pattern /file1 - /file3
+.sp
+By default, each line that matches a pattern is copied to the standard
+output, and if there is more than one file, the file name is output at the
+start of each line, followed by a colon. However, there are options that can
+change how \fBpcregrep\fP behaves. In particular, the \fB-M\fP option makes it
+possible to search for patterns that span line boundaries. What defines a line
+boundary is controlled by the \fB-N\fP (\fB--newline\fP) option.
+.P
+Patterns are limited to 8K or BUFSIZ characters, whichever is the greater.
+BUFSIZ is defined in \fB\fP. When there is more than one pattern
+(specified by the use of \fB-e\fP and/or \fB-f\fP), each pattern is applied to
+each line in the order in which they are defined, except that all the \fB-e\fP
+patterns are tried before the \fB-f\fP patterns.
+.P
+By default, as soon as one pattern matches (or fails to match when \fB-v\fP is
+used), no further patterns are considered. However, if \fB--colour\fP (or
+\fB--color\fP) is used to colour the matching substrings, or if
+\fB--only-matching\fP, \fB--file-offsets\fP, or \fB--line-offsets\fP is used to
+output only the part of the line that matched (either shown literally, or as an
+offset), scanning resumes immediately following the match, so that further
+matches on the same line can be found. If there are multiple patterns, they are
+all tried on the remainder of the line, but patterns that follow the one that
+matched are not tried on the earlier part of the line.
+.P
+This is the same behaviour as GNU grep, but it does mean that the order in
+which multiple patterns are specified can affect the output when one of the
+above options is used.
+.P
+Patterns that can match an empty string are accepted, but empty string
+matches are never recognized. An example is the pattern "(super)?(man)?", in
+which all components are optional. This pattern finds all occurrences of both
+"super" and "man"; the output differs from matching with "super|man" when only
+the matching substrings are being shown.
+.P
+If the \fBLC_ALL\fP or \fBLC_CTYPE\fP environment variable is set,
+\fBpcregrep\fP uses the value to set a locale when calling the PCRE library.
+The \fB--locale\fP option can be used to override this.
+.
+.SH "SUPPORT FOR COMPRESSED FILES"
+.rs
+.sp
+It is possible to compile \fBpcregrep\fP so that it uses \fBlibz\fP or
+\fBlibbz2\fP to read files whose names end in \fB.gz\fP or \fB.bz2\fP,
+respectively. You can find out whether your binary has support for one or both
+of these file types by running it with the \fB--help\fP option. If the
+appropriate support is not present, files are treated as plain text. The
+standard input is always so treated.
+.
+.SH OPTIONS
+.rs
+.sp
+The order in which some of the options appear can affect the output. For
+example, both the \fB-h\fP and \fB-l\fP options affect the printing of file
+names. Whichever comes later in the command line will be the one that takes
+effect.
+.TP 10
+\fB--\fP
+This terminate the list of options. It is useful if the next item on the
+command line starts with a hyphen but is not an option. This allows for the
+processing of patterns and filenames that start with hyphens.
+.TP
+\fB-A\fP \fInumber\fP, \fB--after-context=\fP\fInumber\fP
+Output \fInumber\fP lines of context after each matching line. If filenames
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of \fInumber\fP is expected to be relatively small. However, \fBpcregrep\fP
+guarantees to have up to 8K of following text available for context output.
+.TP
+\fB-B\fP \fInumber\fP, \fB--before-context=\fP\fInumber\fP
+Output \fInumber\fP lines of context before each matching line. If filenames
+and/or line numbers are being output, a hyphen separator is used instead of a
+colon for the context lines. A line containing "--" is output between each
+group of lines, unless they are in fact contiguous in the input file. The value
+of \fInumber\fP is expected to be relatively small. However, \fBpcregrep\fP
+guarantees to have up to 8K of preceding text available for context output.
+.TP
+\fB-C\fP \fInumber\fP, \fB--context=\fP\fInumber\fP
+Output \fInumber\fP lines of context both before and after each matching line.
+This is equivalent to setting both \fB-A\fP and \fB-B\fP to the same value.
+.TP
+\fB-c\fP, \fB--count\fP
+Do not output individual lines from the files that are being scanned; instead
+output the number of lines that would otherwise have been shown. If no lines
+are selected, the number zero is output. If several files are are being
+scanned, a count is output for each of them. However, if the
+\fB--files-with-matches\fP option is also used, only those files whose counts
+are greater than zero are listed. When \fB-c\fP is used, the \fB-A\fP,
+\fB-B\fP, and \fB-C\fP options are ignored.
+.TP
+\fB--colour\fP, \fB--color\fP
+If this option is given without any data, it is equivalent to "--colour=auto".
+If data is required, it must be given in the same shell item, separated by an
+equals sign.
+.TP
+\fB--colour=\fP\fIvalue\fP, \fB--color=\fP\fIvalue\fP
+This option specifies under what circumstances the parts of a line that matched
+a pattern should be coloured in the output. By default, the output is not
+coloured. The value (which is optional, see above) may be "never", "always", or
+"auto". In the latter case, colouring happens only if the standard output is
+connected to a terminal. More resources are used when colouring is enabled,
+because \fBpcregrep\fP has to search for all possible matches in a line, not
+just one, in order to colour them all.
+
+The colour that is used can be specified by setting the environment variable
+PCREGREP_COLOUR or PCREGREP_COLOR. The value of this variable should be a
+string of two numbers, separated by a semicolon. They are copied directly into
+the control string for setting colour on a terminal, so it is your
+responsibility to ensure that they make sense. If neither of the environment
+variables is set, the default is "1;31", which gives red.
+.TP
+\fB-D\fP \fIaction\fP, \fB--devices=\fP\fIaction\fP
+If an input path is not a regular file or a directory, "action" specifies how
+it is to be processed. Valid values are "read" (the default) or "skip"
+(silently skip the path).
+.TP
+\fB-d\fP \fIaction\fP, \fB--directories=\fP\fIaction\fP
+If an input path is a directory, "action" specifies how it is to be processed.
+Valid values are "read" (the default), "recurse" (equivalent to the \fB-r\fP
+option), or "skip" (silently skip the path). In the default case, directories
+are read as if they were ordinary files. In some operating systems the effect
+of reading a directory like this is an immediate end-of-file.
+.TP
+\fB-e\fP \fIpattern\fP, \fB--regex=\fP\fIpattern\fP, \fB--regexp=\fP\fIpattern\fP
+Specify a pattern to be matched. This option can be used multiple times in
+order to specify several patterns. It can also be used as a way of specifying a
+single pattern that starts with a hyphen. When \fB-e\fP is used, no argument
+pattern is taken from the command line; all arguments are treated as file
+names. There is an overall maximum of 100 patterns. They are applied to each
+line in the order in which they are defined until one matches (or fails to
+match if \fB-v\fP is used). If \fB-f\fP is used with \fB-e\fP, the command line
+patterns are matched first, followed by the patterns from the file, independent
+of the order in which these options are specified. Note that multiple use of
+\fB-e\fP is not the same as a single pattern with alternatives. For example,
+X|Y finds the first character in a line that is X or Y, whereas if the two
+patterns are given separately, \fBpcregrep\fP finds X if it is present, even if
+it follows Y in the line. It finds Y only if there is no X in the line. This
+really matters only if you are using \fB-o\fP to show the part(s) of the line
+that matched.
+.TP
+\fB--exclude\fP=\fIpattern\fP
+When \fBpcregrep\fP is searching the files in a directory as a consequence of
+the \fB-r\fP (recursive search) option, any regular files whose names match the
+pattern are excluded. Subdirectories are not excluded by this option; they are
+searched recursively, subject to the \fB--exclude_dir\fP and
+\fB--include_dir\fP options. The pattern is a PCRE regular expression, and is
+matched against the final component of the file name (not the entire path). If
+a file name matches both \fB--include\fP and \fB--exclude\fP, it is excluded.
+There is no short form for this option.
+.TP
+\fB--exclude_dir\fP=\fIpattern\fP
+When \fBpcregrep\fP is searching the contents of a directory as a consequence
+of the \fB-r\fP (recursive search) option, any subdirectories whose names match
+the pattern are excluded. (Note that the \fP--exclude\fP option does not affect
+subdirectories.) The pattern is a PCRE regular expression, and is matched
+against the final component of the name (not the entire path). If a
+subdirectory name matches both \fB--include_dir\fP and \fB--exclude_dir\fP, it
+is excluded. There is no short form for this option.
+.TP
+\fB-F\fP, \fB--fixed-strings\fP
+Interpret each pattern as a list of fixed strings, separated by newlines,
+instead of as a regular expression. The \fB-w\fP (match as a word) and \fB-x\fP
+(match whole line) options can be used with \fB-F\fP. They apply to each of the
+fixed strings. A line is selected if any of the fixed strings are found in it
+(subject to \fB-w\fP or \fB-x\fP, if present).
+.TP
+\fB-f\fP \fIfilename\fP, \fB--file=\fP\fIfilename\fP
+Read a number of patterns from the file, one per line, and match them against
+each line of input. A data line is output if any of the patterns match it. The
+filename can be given as "-" to refer to the standard input. When \fB-f\fP is
+used, patterns specified on the command line using \fB-e\fP may also be
+present; they are tested before the file's patterns. However, no other pattern
+is taken from the command line; all arguments are treated as file names. There
+is an overall maximum of 100 patterns. Trailing white space is removed from
+each line, and blank lines are ignored. An empty file contains no patterns and
+therefore matches nothing. See also the comments about multiple patterns versus
+a single pattern with alternatives in the description of \fB-e\fP above.
+.TP
+\fB--file-offsets\fP
+Instead of showing lines or parts of lines that match, show each match as an
+offset from the start of the file and a length, separated by a comma. In this
+mode, no context is shown. That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP
+options are ignored. If there is more than one match in a line, each of them is
+shown separately. This option is mutually exclusive with \fB--line-offsets\fP
+and \fB--only-matching\fP.
+.TP
+\fB-H\fP, \fB--with-filename\fP
+Force the inclusion of the filename at the start of output lines when searching
+a single file. By default, the filename is not shown in this case. For matching
+lines, the filename is followed by a colon; for context lines, a hyphen
+separator is used. If a line number is also being output, it follows the file
+name.
+.TP
+\fB-h\fP, \fB--no-filename\fP
+Suppress the output filenames when searching multiple files. By default,
+filenames are shown when multiple files are searched. For matching lines, the
+filename is followed by a colon; for context lines, a hyphen separator is used.
+If a line number is also being output, it follows the file name.
+.TP
+\fB--help\fP
+Output a help message, giving brief details of the command options and file
+type support, and then exit.
+.TP
+\fB-i\fP, \fB--ignore-case\fP
+Ignore upper/lower case distinctions during comparisons.
+.TP
+\fB--include\fP=\fIpattern\fP
+When \fBpcregrep\fP is searching the files in a directory as a consequence of
+the \fB-r\fP (recursive search) option, only those regular files whose names
+match the pattern are included. Subdirectories are always included and searched
+recursively, subject to the \fP--include_dir\fP and \fB--exclude_dir\fP
+options. The pattern is a PCRE regular expression, and is matched against the
+final component of the file name (not the entire path). If a file name matches
+both \fB--include\fP and \fB--exclude\fP, it is excluded. There is no short
+form for this option.
+.TP
+\fB--include_dir\fP=\fIpattern\fP
+When \fBpcregrep\fP is searching the contents of a directory as a consequence
+of the \fB-r\fP (recursive search) option, only those subdirectories whose
+names match the pattern are included. (Note that the \fB--include\fP option
+does not affect subdirectories.) The pattern is a PCRE regular expression, and
+is matched against the final component of the name (not the entire path). If a
+subdirectory name matches both \fB--include_dir\fP and \fB--exclude_dir\fP, it
+is excluded. There is no short form for this option.
+.TP
+\fB-L\fP, \fB--files-without-match\fP
+Instead of outputting lines from the files, just output the names of the files
+that do not contain any lines that would have been output. Each file name is
+output once, on a separate line.
+.TP
+\fB-l\fP, \fB--files-with-matches\fP
+Instead of outputting lines from the files, just output the names of the files
+containing lines that would have been output. Each file name is output
+once, on a separate line. Searching normally stops as soon as a matching line
+is found in a file. However, if the \fB-c\fP (count) option is also used,
+matching continues in order to obtain the correct count, and those files that
+have at least one match are listed along with their counts. Using this option
+with \fB-c\fP is a way of suppressing the listing of files with no matches.
+.TP
+\fB--label\fP=\fIname\fP
+This option supplies a name to be used for the standard input when file names
+are being output. If not supplied, "(standard input)" is used. There is no
+short form for this option.
+.TP
+\fB--line-offsets\fP
+Instead of showing lines or parts of lines that match, show each match as a
+line number, the offset from the start of the line, and a length. The line
+number is terminated by a colon (as usual; see the \fB-n\fP option), and the
+offset and length are separated by a comma. In this mode, no context is shown.
+That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP options are ignored. If there is
+more than one match in a line, each of them is shown separately. This option is
+mutually exclusive with \fB--file-offsets\fP and \fB--only-matching\fP.
+.TP
+\fB--locale\fP=\fIlocale-name\fP
+This option specifies a locale to be used for pattern matching. It overrides
+the value in the \fBLC_ALL\fP or \fBLC_CTYPE\fP environment variables. If no
+locale is specified, the PCRE library's default (usually the "C" locale) is
+used. There is no short form for this option.
+.TP
+\fB-M\fP, \fB--multiline\fP
+Allow patterns to match more than one line. When this option is given, patterns
+may usefully contain literal newline characters and internal occurrences of ^
+and $ characters. The output for any one match may consist of more than one
+line. When this option is set, the PCRE library is called in "multiline" mode.
+There is a limit to the number of lines that can be matched, imposed by the way
+that \fBpcregrep\fP buffers the input file as it scans it. However,
+\fBpcregrep\fP ensures that at least 8K characters or the rest of the document
+(whichever is the shorter) are available for forward matching, and similarly
+the previous 8K characters (or all the previous characters, if fewer than 8K)
+are guaranteed to be available for lookbehind assertions.
+.TP
+\fB-N\fP \fInewline-type\fP, \fB--newline=\fP\fInewline-type\fP
+The PCRE library supports five different conventions for indicating
+the ends of lines. They are the single-character sequences CR (carriage return)
+and LF (linefeed), the two-character sequence CRLF, an "anycrlf" convention,
+which recognizes any of the preceding three types, and an "any" convention, in
+which any Unicode line ending sequence is assumed to end a line. The Unicode
+sequences are the three just mentioned, plus VT (vertical tab, U+000B), FF
+(formfeed, U+000C), NEL (next line, U+0085), LS (line separator, U+2028), and
+PS (paragraph separator, U+2029).
+.sp
+When the PCRE library is built, a default line-ending sequence is specified.
+This is normally the standard sequence for the operating system. Unless
+otherwise specified by this option, \fBpcregrep\fP uses the library's default.
+The possible values for this option are CR, LF, CRLF, ANYCRLF, or ANY. This
+makes it possible to use \fBpcregrep\fP on files that have come from other
+environments without having to modify their line endings. If the data that is
+being scanned does not agree with the convention set by this option,
+\fBpcregrep\fP may behave in strange ways.
+.TP
+\fB-n\fP, \fB--line-number\fP
+Precede each output line by its line number in the file, followed by a colon
+for matching lines or a hyphen for context lines. If the filename is also being
+output, it precedes the line number. This option is forced if
+\fB--line-offsets\fP is used.
+.TP
+\fB-o\fP, \fB--only-matching\fP
+Show only the part of the line that matched a pattern. In this mode, no
+context is shown. That is, the \fB-A\fP, \fB-B\fP, and \fB-C\fP options are
+ignored. If there is more than one match in a line, each of them is shown
+separately. If \fB-o\fP is combined with \fB-v\fP (invert the sense of the
+match to find non-matching lines), no output is generated, but the return code
+is set appropriately. This option is mutually exclusive with
+\fB--file-offsets\fP and \fB--line-offsets\fP.
+.TP
+\fB-q\fP, \fB--quiet\fP
+Work quietly, that is, display nothing except error messages. The exit
+status indicates whether or not any matches were found.
+.TP
+\fB-r\fP, \fB--recursive\fP
+If any given path is a directory, recursively scan the files it contains,
+taking note of any \fB--include\fP and \fB--exclude\fP settings. By default, a
+directory is read as a normal file; in some operating systems this gives an
+immediate end-of-file. This option is a shorthand for setting the \fB-d\fP
+option to "recurse".
+.TP
+\fB-s\fP, \fB--no-messages\fP
+Suppress error messages about non-existent or unreadable files. Such files are
+quietly skipped. However, the return code is still 2, even if matches were
+found in other files.
+.TP
+\fB-u\fP, \fB--utf-8\fP
+Operate in UTF-8 mode. This option is available only if PCRE has been compiled
+with UTF-8 support. Both patterns and subject lines must be valid strings of
+UTF-8 characters.
+.TP
+\fB-V\fP, \fB--version\fP
+Write the version numbers of \fBpcregrep\fP and the PCRE library that is being
+used to the standard error stream.
+.TP
+\fB-v\fP, \fB--invert-match\fP
+Invert the sense of the match, so that lines which do \fInot\fP match any of
+the patterns are the ones that are found.
+.TP
+\fB-w\fP, \fB--word-regex\fP, \fB--word-regexp\fP
+Force the patterns to match only whole words. This is equivalent to having \eb
+at the start and end of the pattern.
+.TP
+\fB-x\fP, \fB--line-regex\fP, \fB--line-regexp\fP
+Force the patterns to be anchored (each must start matching at the beginning of
+a line) and in addition, require them to match entire lines. This is
+equivalent to having ^ and $ characters at the start and end of each
+alternative branch in every pattern.
+.
+.
+.SH "ENVIRONMENT VARIABLES"
+.rs
+.sp
+The environment variables \fBLC_ALL\fP and \fBLC_CTYPE\fP are examined, in that
+order, for a locale. The first one that is set is used. This can be overridden
+by the \fB--locale\fP option. If no locale is set, the PCRE library's default
+(usually the "C" locale) is used.
+.
+.
+.SH "NEWLINES"
+.rs
+.sp
+The \fB-N\fP (\fB--newline\fP) option allows \fBpcregrep\fP to scan files with
+different newline conventions from the default. However, the setting of this
+option does not affect the way in which \fBpcregrep\fP writes information to
+the standard error and output streams. It uses the string "\en" in C
+\fBprintf()\fP calls to indicate newlines, relying on the C I/O library to
+convert this to an appropriate sequence if the output is sent to a file.
+.
+.
+.SH "OPTIONS COMPATIBILITY"
+.rs
+.sp
+The majority of short and long forms of \fBpcregrep\fP's options are the same
+as in the GNU \fBgrep\fP program. Any long option of the form
+\fB--xxx-regexp\fP (GNU terminology) is also available as \fB--xxx-regex\fP
+(PCRE terminology). However, the \fB--locale\fP, \fB-M\fP, \fB--multiline\fP,
+\fB-u\fP, and \fB--utf-8\fP options are specific to \fBpcregrep\fP. If both the
+\fB-c\fP and \fB-l\fP options are given, GNU grep lists only file names,
+without counts, but \fBpcregrep\fP gives the counts.
+.
+.
+.SH "OPTIONS WITH DATA"
+.rs
+.sp
+There are four different ways in which an option with data can be specified.
+If a short form option is used, the data may follow immediately, or in the next
+command line item. For example:
+.sp
+  -f/some/file
+  -f /some/file
+.sp
+If a long form option is used, the data may appear in the same command line
+item, separated by an equals character, or (with one exception) it may appear
+in the next command line item. For example:
+.sp
+  --file=/some/file
+  --file /some/file
+.sp
+Note, however, that if you want to supply a file name beginning with ~ as data
+in a shell command, and have the shell expand ~ to a home directory, you must
+separate the file name from the option, because the shell does not treat ~
+specially unless it is at the start of an item.
+.P
+The exception to the above is the \fB--colour\fP (or \fB--color\fP) option,
+for which the data is optional. If this option does have data, it must be given
+in the first form, using an equals character. Otherwise it will be assumed that
+it has no data.
+.
+.
+.SH "MATCHING ERRORS"
+.rs
+.sp
+It is possible to supply a regular expression that takes a very long time to
+fail to match certain lines. Such patterns normally involve nested indefinite
+repeats, for example: (a+)*\ed when matched against a line of a's with no final
+digit. The PCRE matching function has a resource limit that causes it to abort
+in these circumstances. If this happens, \fBpcregrep\fP outputs an error
+message and the line that caused the problem to the standard error stream. If
+there are more than 20 such errors, \fBpcregrep\fP gives up.
+.
+.
+.SH DIAGNOSTICS
+.rs
+.sp
+Exit status is 0 if any matches were found, 1 if no matches were found, and 2
+for syntax errors and non-existent or inacessible files (even if matches were
+found in other files) or too many matching errors. Using the \fB-s\fP option to
+suppress error messages about inaccessble files does not affect the return
+code.

+NAME
+       pcregrep - a grep with Perl-compatible regular expressions.
+
+
+SYNOPSIS
+       pcregrep [options] [long options] [pattern] [path1 path2 ...]
+
+
+DESCRIPTION
+
+       pcregrep  searches  files  for  character  patterns, in the same way as
+       other grep commands do, but it uses the PCRE regular expression library
+       to support patterns that are compatible with the regular expressions of
+       Perl 5. See pcrepattern(3) for a full description of syntax and  seman-
+       tics of the regular expressions that PCRE supports.
+
+       Patterns,  whether  supplied on the command line or in a separate file,
+       are given without delimiters. For example:
+
+         pcregrep Thursday /etc/motd
+
+       If you attempt to use delimiters (for example, by surrounding a pattern
+       with  slashes,  as  is common in Perl scripts), they are interpreted as
+       part of the pattern. Quotes can of course be used to  delimit  patterns
+       on  the  command  line  because  they are interpreted by the shell, and
+       indeed they are required if a pattern contains  white  space  or  shell
+       metacharacters.
+
+       The  first  argument that follows any option settings is treated as the
+       single pattern to be matched when neither -e nor -f is  present.   Con-
+       versely,  when  one  or  both of these options are used to specify pat-
+       terns, all arguments are treated as path names. At least one of -e, -f,
+       or an argument pattern must be provided.
+
+       If no files are specified, pcregrep reads the standard input. The stan-
+       dard input can also be referenced by a  name  consisting  of  a  single
+       hyphen.  For example:
+
+         pcregrep some-pattern /file1 - /file3
+
+       By  default, each line that matches a pattern is copied to the standard
+       output, and if there is more than one file, the file name is output  at
+       the start of each line, followed by a colon. However, there are options
+       that can change how pcregrep behaves.  In  particular,  the  -M  option
+       makes  it  possible  to  search for patterns that span line boundaries.
+       What defines a line  boundary  is  controlled  by  the  -N  (--newline)
+       option.
+
+       Patterns  are  limited  to  8K  or  BUFSIZ characters, whichever is the
+       greater.  BUFSIZ is defined in . When there is more  than  one
+       pattern (specified by the use of -e and/or -f), each pattern is applied
+       to each line in the order in which they are defined,  except  that  all
+       the -e patterns are tried before the -f patterns.
+
+       By  default,  as soon as one pattern matches (or fails to match when -v
+       is used), no further patterns are considered. However, if --colour  (or
+       --color) is used to colour the matching substrings, or if --only-match-
+       ing, --file-offsets, or --line-offsets is used to output only the  part
+       of  the  line  that  matched (either shown literally, or as an offset),
+       scanning resumes immediately  following  the  match,  so  that  further
+       matches  on the same line can be found. If there are multiple patterns,
+       they are all tried on the remainder of the line, but patterns that fol-
+       low the one that matched are not tried on the earlier part of the line.
+
+       This is the same behaviour as GNU grep, but it does mean that the order
+       in which multiple patterns are specified can affect the output when one
+       of the above options is used.
+
+       Patterns  that can match an empty string are accepted, but empty string
+       matches   are   never   recognized.   An   example   is   the   pattern
+       "(super)?(man)?",  in  which  all components are optional. This pattern
+       finds all occurrences of both "super" and  "man";  the  output  differs
+       from  matching  with  "super|man" when only the matching substrings are
+       being shown.
+
+       If the LC_ALL or LC_CTYPE environment variable is  set,  pcregrep  uses
+       the  value to set a locale when calling the PCRE library.  The --locale
+       option can be used to override this.
+
+
+SUPPORT FOR COMPRESSED FILES
+
+       It is possible to compile pcregrep so that it uses libz  or  libbz2  to
+       read  files  whose names end in .gz or .bz2, respectively. You can find
+       out whether your binary has support for one or both of these file types
+       by running it with the --help option. If the appropriate support is not
+       present, files are treated as plain text. The standard input is  always
+       so treated.
+
+
+OPTIONS
+
+       The  order  in  which some of the options appear can affect the output.
+       For example, both the -h and -l options affect  the  printing  of  file
+       names.  Whichever  comes later in the command line will be the one that
+       takes effect.
+
+       --        This terminate the list of options. It is useful if the  next
+                 item  on  the command line starts with a hyphen but is not an
+                 option. This allows for the processing of patterns and  file-
+                 names that start with hyphens.
+
+       -A number, --after-context=number
+                 Output  number  lines of context after each matching line. If
+                 filenames and/or line numbers are being output, a hyphen sep-
+                 arator  is  used  instead of a colon for the context lines. A
+                 line containing "--" is output between each group  of  lines,
+                 unless  they  are  in  fact contiguous in the input file. The
+                 value of number is expected to be relatively small.  However,
+                 pcregrep guarantees to have up to 8K of following text avail-
+                 able for context output.
+
+       -B number, --before-context=number
+                 Output number lines of context before each matching line.  If
+                 filenames and/or line numbers are being output, a hyphen sep-
+                 arator is used instead of a colon for the  context  lines.  A
+                 line  containing  "--" is output between each group of lines,
+                 unless they are in fact contiguous in  the  input  file.  The
+                 value  of number is expected to be relatively small. However,
+                 pcregrep guarantees to have up to 8K of preceding text avail-
+                 able for context output.
+
+       -C number, --context=number
+                 Output  number  lines  of  context both before and after each
+                 matching line.  This is equivalent to setting both -A and  -B
+                 to the same value.
+
+       -c, --count
+                 Do  not output individual lines from the files that are being
+                 scanned; instead output the number of lines that would other-
+                 wise  have  been  shown. If no lines are selected, the number
+                 zero is output. If several files are  are  being  scanned,  a
+                 count  is  output  for each of them. However, if the --files-
+                 with-matches option is also  used,  only  those  files  whose
+                 counts are greater than zero are listed. When -c is used, the
+                 -A, -B, and -C options are ignored.
+
+       --colour, --color
+                 If this option is given without any data, it is equivalent to
+                 "--colour=auto".   If  data  is required, it must be given in
+                 the same shell item, separated by an equals sign.
+
+       --colour=value, --color=value
+                 This option specifies under what circumstances the parts of a
+                 line that matched a pattern should be coloured in the output.
+                 By default, the output is not coloured. The value  (which  is
+                 optional,  see above) may be "never", "always", or "auto". In
+                 the latter case, colouring happens only if the standard  out-
+                 put  is connected to a terminal. More resources are used when
+                 colouring is enabled, because pcregrep has to search for  all
+                 possible  matches in a line, not just one, in order to colour
+                 them all.
+
+                 The colour that is used can be specified by setting the envi-
+                 ronment variable PCREGREP_COLOUR or PCREGREP_COLOR. The value
+                 of this variable should be a string of two numbers, separated
+                 by  a  semicolon.  They  are copied directly into the control
+                 string for setting colour  on  a  terminal,  so  it  is  your
+                 responsibility  to ensure that they make sense. If neither of
+                 the environment variables is  set,  the  default  is  "1;31",
+                 which gives red.
+
+       -D action, --devices=action
+                 If  an  input  path  is  not  a  regular file or a directory,
+                 "action" specifies how it is to be  processed.  Valid  values
+                 are "read" (the default) or "skip" (silently skip the path).
+
+       -d action, --directories=action
+                 If an input path is a directory, "action" specifies how it is
+                 to be processed.  Valid  values  are  "read"  (the  default),
+                 "recurse"  (equivalent to the -r option), or "skip" (silently
+                 skip the path). In the default case, directories are read  as
+                 if  they  were  ordinary files. In some operating systems the
+                 effect of reading a directory like this is an immediate  end-
+                 of-file.
+
+       -e pattern, --regex=pattern, --regexp=pattern
+                 Specify a pattern to be matched. This option can be used mul-
+                 tiple times in order to specify several patterns. It can also
+                 be  used  as a way of specifying a single pattern that starts
+                 with a hyphen. When -e is used, no argument pattern is  taken
+                 from  the  command  line;  all  arguments are treated as file
+                 names. There is an overall maximum of 100 patterns. They  are
+                 applied  to  each line in the order in which they are defined
+                 until one matches (or fails to match if -v is used). If -f is
+                 used  with  -e,  the command line patterns are matched first,
+                 followed by the patterns from the file,  independent  of  the
+                 order  in which these options are specified. Note that multi-
+                 ple use of -e is not the same as a single pattern with alter-
+                 natives. For example, X|Y finds the first character in a line
+                 that is X or Y, whereas if the two patterns are  given  sepa-
+                 rately, pcregrep finds X if it is present, even if it follows
+                 Y in the line. It finds Y only if there is no X in the  line.
+                 This  really  matters  only  if  you are using -o to show the
+                 part(s) of the line that matched.
+
+       --exclude=pattern
+                 When pcregrep is searching the files in a directory as a con-
+                 sequence  of  the  -r  (recursive search) option, any regular
+                 files whose names match the pattern are excluded. Subdirecto-
+                 ries  are  not  excluded  by  this  option; they are searched
+                 recursively, subject to the --exclude_dir  and  --include_dir
+                 options.  The  pattern  is  a PCRE regular expression, and is
+                 matched against the final component of the file name (not the
+                 entire  path).  If  a  file  name  matches both --include and
+                 --exclude, it is excluded.  There is no short form  for  this
+                 option.
+
+       --exclude_dir=pattern
+                 When  pcregrep  is searching the contents of a directory as a
+                 consequence of the -r (recursive search) option,  any  subdi-
+                 rectories  whose  names match the pattern are excluded. (Note
+                 that the --exclude option does  not  affect  subdirectories.)
+                 The  pattern  is  a  PCRE  regular expression, and is matched
+                 against the final component  of  the  name  (not  the  entire
+                 path).  If a subdirectory name matches both --include_dir and
+                 --exclude_dir, it is excluded. There is  no  short  form  for
+                 this option.
+
+       -F, --fixed-strings
+                 Interpret  each pattern as a list of fixed strings, separated
+                 by newlines, instead of  as  a  regular  expression.  The  -w
+                 (match  as  a  word) and -x (match whole line) options can be
+                 used with -F. They apply to each of the fixed strings. A line
+                 is selected if any of the fixed strings are found in it (sub-
+                 ject to -w or -x, if present).
+
+       -f filename, --file=filename
+                 Read a number of patterns from the file, one  per  line,  and
+                 match  them against each line of input. A data line is output
+                 if any of the patterns match it. The filename can be given as
+                 "-" to refer to the standard input. When -f is used, patterns
+                 specified on the command line using -e may also  be  present;
+                 they are tested before the file's patterns. However, no other
+                 pattern is taken from the command  line;  all  arguments  are
+                 treated  as  file  names.  There is an overall maximum of 100
+                 patterns. Trailing white space is removed from each line, and
+                 blank  lines  are ignored. An empty file contains no patterns
+                 and therefore matches nothing. See also  the  comments  about
+                 multiple  patterns  versus a single pattern with alternatives
+                 in the description of -e above.
+
+       --file-offsets
+                 Instead of showing lines or parts of lines that  match,  show
+                 each  match  as  an  offset  from the start of the file and a
+                 length, separated by a comma. In this  mode,  no  context  is
+                 shown.  That  is,  the -A, -B, and -C options are ignored. If
+                 there is more than one match in a line, each of them is shown
+                 separately.  This  option  is mutually exclusive with --line-
+                 offsets and --only-matching.
+
+       -H, --with-filename
+                 Force the inclusion of the filename at the  start  of  output
+                 lines  when searching a single file. By default, the filename
+                 is not shown in this case. For matching lines,  the  filename
+                 is followed by a colon; for context lines, a hyphen separator
+                 is used. If a line number is also being  output,  it  follows
+                 the file name.
+
+       -h, --no-filename
+                 Suppress  the output filenames when searching multiple files.
+                 By default, filenames  are  shown  when  multiple  files  are
+                 searched.  For  matching lines, the filename is followed by a
+                 colon; for context lines, a hyphen separator is used.   If  a
+                 line number is also being output, it follows the file name.
+
+       --help    Output  a  help  message, giving brief details of the command
+                 options and file type support, and then exit.
+
+       -i, --ignore-case
+                 Ignore upper/lower case distinctions during comparisons.
+
+       --include=pattern
+                 When pcregrep is searching the files in a directory as a con-
+                 sequence of the -r (recursive search) option, only those reg-
+                 ular files whose names match the pattern are included. Subdi-
+                 rectories  are always included and searched recursively, sub-
+                 ject to the --include_dir and --exclude_dir options. The pat-
+                 tern is a PCRE regular expression, and is matched against the
+                 final component of the file name (not the entire path). If  a
+                 file  name  matches  both  --include  and  --exclude,  it  is
+                 excluded. There is no short form for this option.
+
+       --include_dir=pattern
+                 When pcregrep is searching the contents of a directory  as  a
+                 consequence  of  the -r (recursive search) option, only those
+                 subdirectories whose names match the  pattern  are  included.
+                 (Note  that  the --include option does not affect subdirecto-
+                 ries.) The pattern is  a  PCRE  regular  expression,  and  is
+                 matched  against  the  final  component  of the name (not the
+                 entire  path).  If   a   subdirectory   name   matches   both
+                 --include_dir  and --exclude_dir, it is excluded. There is no
+                 short form for this option.
+
+       -L, --files-without-match
+                 Instead of outputting lines from the files, just  output  the
+                 names  of  the files that do not contain any lines that would
+                 have been output. Each file name is output once, on  a  sepa-
+                 rate line.
+
+       -l, --files-with-matches
+                 Instead  of  outputting lines from the files, just output the
+                 names of the files containing lines that would have been out-
+                 put.  Each  file  name  is  output  once, on a separate line.
+                 Searching normally stops as soon as a matching line is  found
+                 in  a  file.  However, if the -c (count) option is also used,
+                 matching continues in order to obtain the correct count,  and
+                 those  files  that  have  at least one match are listed along
+                 with their counts. Using this option with -c is a way of sup-
+                 pressing the listing of files with no matches.
+
+       --label=name
+                 This option supplies a name to be used for the standard input
+                 when file names are being output. If not supplied, "(standard
+                 input)" is used. There is no short form for this option.
+
+       --line-offsets
+                 Instead  of  showing lines or parts of lines that match, show
+                 each match as a line number, the offset from the start of the
+                 line,  and a length. The line number is terminated by a colon
+                 (as usual; see the -n option), and the offset and length  are
+                 separated  by  a  comma.  In  this mode, no context is shown.
+                 That is, the -A, -B, and -C options are ignored. If there  is
+                 more  than  one  match in a line, each of them is shown sepa-
+                 rately. This option is mutually exclusive with --file-offsets
+                 and --only-matching.
+
+       --locale=locale-name
+                 This  option specifies a locale to be used for pattern match-
+                 ing. It overrides the value in the LC_ALL or  LC_CTYPE  envi-
+                 ronment  variables.  If  no  locale  is  specified,  the PCRE
+                 library's default (usually the "C" locale) is used. There  is
+                 no short form for this option.
+
+       -M, --multiline
+                 Allow  patterns to match more than one line. When this option
+                 is given, patterns may usefully contain literal newline char-
+                 acters  and  internal  occurrences of ^ and $ characters. The
+                 output for any one match may consist of more than  one  line.
+                 When  this option is set, the PCRE library is called in "mul-
+                 tiline" mode.  There is a limit to the number of  lines  that
+                 can  be matched, imposed by the way that pcregrep buffers the
+                 input file as it scans it. However, pcregrep ensures that  at
+                 least 8K characters or the rest of the document (whichever is
+                 the shorter) are available for forward  matching,  and  simi-
+                 larly the previous 8K characters (or all the previous charac-
+                 ters, if fewer than 8K) are guaranteed to  be  available  for
+                 lookbehind assertions.
+
+       -N newline-type, --newline=newline-type
+                 The  PCRE  library  supports  five  different conventions for
+                 indicating the ends of lines. They are  the  single-character
+                 sequences  CR  (carriage  return) and LF (linefeed), the two-
+                 character sequence CRLF, an "anycrlf" convention, which  rec-
+                 ognizes  any  of the preceding three types, and an "any" con-
+                 vention, in which any Unicode line ending sequence is assumed
+                 to  end a line. The Unicode sequences are the three just men-
+                 tioned,  plus  VT  (vertical  tab,  U+000B),  FF   (formfeed,
+                 U+000C),   NEL  (next  line,  U+0085),  LS  (line  separator,
+                 U+2028), and PS (paragraph separator, U+2029).
+
+                 When  the  PCRE  library  is  built,  a  default  line-ending
+                 sequence   is  specified.   This  is  normally  the  standard
+                 sequence for the operating system. Unless otherwise specified
+                 by  this  option,  pcregrep  uses the library's default.  The
+                 possible values for this option are CR, LF, CRLF, ANYCRLF, or
+                 ANY.  This  makes  it  possible to use pcregrep on files that
+                 have come from other environments without  having  to  modify
+                 their  line  endings.  If the data that is being scanned does
+                 not agree with the convention set by  this  option,  pcregrep
+                 may behave in strange ways.
+
+       -n, --line-number
+                 Precede each output line by its line number in the file, fol-
+                 lowed by a colon for matching lines or a hyphen  for  context
+                 lines.  If the filename is also being output, it precedes the
+                 line number. This option is forced if --line-offsets is used.
+
+       -o, --only-matching
+                 Show only the part of the line that  matched  a  pattern.  In
+                 this  mode,  no context is shown. That is, the -A, -B, and -C
+                 options are ignored. If there is more than  one  match  in  a
+                 line,  each  of  them  is shown separately. If -o is combined
+                 with -v (invert the sense of the match to  find  non-matching
+                 lines),  no  output  is generated, but the return code is set
+                 appropriately. This option is mutually exclusive with --file-
+                 offsets and --line-offsets.
+
+       -q, --quiet
+                 Work quietly, that is, display nothing except error messages.
+                 The exit status indicates whether or  not  any  matches  were
+                 found.
+
+       -r, --recursive
+                 If  any given path is a directory, recursively scan the files
+                 it contains, taking note of any --include and --exclude  set-
+                 tings.  By  default, a directory is read as a normal file; in
+                 some operating systems this gives an  immediate  end-of-file.
+                 This  option  is  a  shorthand  for  setting the -d option to
+                 "recurse".
+
+       -s, --no-messages
+                 Suppress error  messages  about  non-existent  or  unreadable
+                 files.  Such  files  are quietly skipped. However, the return
+                 code is still 2, even if matches were found in other files.
+
+       -u, --utf-8
+                 Operate in UTF-8 mode. This option is available only if  PCRE
+                 has  been compiled with UTF-8 support. Both patterns and sub-
+                 ject lines must be valid strings of UTF-8 characters.
+
+       -V, --version
+                 Write the version numbers of pcregrep and  the  PCRE  library
+                 that is being used to the standard error stream.
+
+       -v, --invert-match
+                 Invert  the  sense  of  the match, so that lines which do not
+                 match any of the patterns are the ones that are found.
+
+       -w, --word-regex, --word-regexp
+                 Force the patterns to match only whole words. This is equiva-
+                 lent to having \b at the start and end of the pattern.
+
+       -x, --line-regex, --line-regexp
+                 Force  the  patterns to be anchored (each must start matching
+                 at the beginning of a line) and in addition, require them  to
+                 match  entire  lines.  This  is  equivalent to having ^ and $
+                 characters at the start and end of each alternative branch in
+                 every pattern.
+
+
+ENVIRONMENT VARIABLES
+
+       The  environment  variables  LC_ALL  and LC_CTYPE are examined, in that
+       order, for a locale. The first one that is set is  used.  This  can  be
+       overridden  by  the  --locale  option.  If  no  locale is set, the PCRE
+       library's default (usually the "C" locale) is used.
+
+
+NEWLINES
+
+       The -N (--newline) option allows pcregrep to scan files with  different
+       newline  conventions  from  the  default.  However, the setting of this
+       option does not affect the way in which pcregrep writes information  to
+       the  standard  error  and  output streams. It uses the string "\n" in C
+       printf() calls to indicate newlines, relying on the C  I/O  library  to
+       convert  this  to  an  appropriate  sequence if the output is sent to a
+       file.
+
+
+OPTIONS COMPATIBILITY
+
+       The majority of short and long forms of pcregrep's options are the same
+       as  in  the  GNU grep program. Any long option of the form --xxx-regexp
+       (GNU terminology) is also available as --xxx-regex (PCRE  terminology).
+       However,  the  --locale,  -M,  --multiline, -u, and --utf-8 options are
+       specific to pcregrep. If both the -c and -l options are given, GNU grep
+       lists only file names, without counts, but pcregrep gives the counts.
+
+
+OPTIONS WITH DATA
+
+       There are four different ways in which an option with data can be spec-
+       ified.  If a short form option is used, the  data  may  follow  immedi-
+       ately, or in the next command line item. For example:
+
+         -f/some/file
+         -f /some/file
+
+       If  a long form option is used, the data may appear in the same command
+       line item, separated by an equals character, or (with one exception) it
+       may appear in the next command line item. For example:
+
+         --file=/some/file
+         --file /some/file
+
+       Note,  however, that if you want to supply a file name beginning with ~
+       as data in a shell command, and have the  shell  expand  ~  to  a  home
+       directory, you must separate the file name from the option, because the
+       shell does not treat ~ specially unless it is at the start of an item.
+
+       The exception to the above is the --colour  (or  --color)  option,  for
+       which  the  data is optional. If this option does have data, it must be
+       given in the first form, using an equals character. Otherwise  it  will
+       be assumed that it has no data.
+
+
+MATCHING ERRORS
+
+       It  is  possible  to supply a regular expression that takes a very long
+       time to fail to match certain lines.  Such  patterns  normally  involve
+       nested  indefinite repeats, for example: (a+)*\d when matched against a
+       line of a's with no final digit.  The  PCRE  matching  function  has  a
+       resource  limit that causes it to abort in these circumstances. If this
+       happens, pcregrep outputs an error message and the line that caused the
+       problem  to  the  standard error stream. If there are more than 20 such
+       errors, pcregrep gives up.
+
+
+DIAGNOSTICS
+
+       Exit status is 0 if any matches were found, 1 if no matches were found,
+       and  2 for syntax errors and non-existent or inacessible files (even if
+       matches were found in other files) or too many matching  errors.  Using
+       the  -s  option to suppress error messages about inaccessble files does
+       not affect the return code.

+.TH PCREMATCHING 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH "PCRE MATCHING ALGORITHMS"
+.rs
+.sp
+This document describes the two different algorithms that are available in PCRE
+for matching a compiled regular expression against a given subject string. The
+"standard" algorithm is the one provided by the \fBpcre_exec()\fP function.
+This works in the same was as Perl's matching function, and provides a
+Perl-compatible matching operation.
+.P
+An alternative algorithm is provided by the \fBpcre_dfa_exec()\fP function;
+this operates in a different way, and is not Perl-compatible. It has advantages
+and disadvantages compared with the standard algorithm, and these are described
+below.
+.P
+When there is only one possible way in which a given subject string can match a
+pattern, the two algorithms give the same answer. A difference arises, however,
+when there are multiple possibilities. For example, if the pattern
+.sp
+  ^<.*>
+.sp
+is matched against the string
+.sp
+    
+.sp
+there are three possible answers. The standard algorithm finds only one of
+them, whereas the alternative algorithm finds all three.
+.
+.SH "REGULAR EXPRESSIONS AS TREES"
+.rs
+.sp
+The set of strings that are matched by a regular expression can be represented
+as a tree structure. An unlimited repetition in the pattern makes the tree of
+infinite size, but it is still a tree. Matching the pattern to a given subject
+string (from a given starting point) can be thought of as a search of the tree.
+There are two ways to search a tree: depth-first and breadth-first, and these
+correspond to the two matching algorithms provided by PCRE.
+.
+.SH "THE STANDARD MATCHING ALGORITHM"
+.rs
+.sp
+In the terminology of Jeffrey Friedl's book "Mastering Regular
+Expressions", the standard algorithm is an "NFA algorithm". It conducts a
+depth-first search of the pattern tree. That is, it proceeds along a single
+path through the tree, checking that the subject matches what is required. When
+there is a mismatch, the algorithm tries any alternatives at the current point,
+and if they all fail, it backs up to the previous branch point in the tree, and
+tries the next alternative branch at that level. This often involves backing up
+(moving to the left) in the subject string as well. The order in which
+repetition branches are tried is controlled by the greedy or ungreedy nature of
+the quantifier.
+.P
+If a leaf node is reached, a matching string has been found, and at that point
+the algorithm stops. Thus, if there is more than one possible match, this
+algorithm returns the first one that it finds. Whether this is the shortest,
+the longest, or some intermediate length depends on the way the greedy and
+ungreedy repetition quantifiers are specified in the pattern.
+.P
+Because it ends up with a single path through the tree, it is relatively
+straightforward for this algorithm to keep track of the substrings that are
+matched by portions of the pattern in parentheses. This provides support for
+capturing parentheses and back references.
+.
+.SH "THE ALTERNATIVE MATCHING ALGORITHM"
+.rs
+.sp
+This algorithm conducts a breadth-first search of the tree. Starting from the
+first matching point in the subject, it scans the subject string from left to
+right, once, character by character, and as it does this, it remembers all the
+paths through the tree that represent valid matches. In Friedl's terminology,
+this is a kind of "DFA algorithm", though it is not implemented as a
+traditional finite state machine (it keeps multiple states active
+simultaneously).
+.P
+Although the general principle of this matching algorithm is that it scans the
+subject string only once, without backtracking, there is one exception: when a
+lookaround assertion is encountered, the characters following or preceding the
+current point have to be independently inspected.
+.P
+The scan continues until either the end of the subject is reached, or there are
+no more unterminated paths. At this point, terminated paths represent the
+different matching possibilities (if there are none, the match has failed).
+Thus, if there is more than one possible match, this algorithm finds all of
+them, and in particular, it finds the longest. There is an option to stop the
+algorithm after the first match (which is necessarily the shortest) is found.
+.P
+Note that all the matches that are found start at the same point in the
+subject. If the pattern
+.sp
+  cat(er(pillar)?)
+.sp
+is matched against the string "the caterpillar catchment", the result will be
+the three strings "cat", "cater", and "caterpillar" that start at the fourth
+character of the subject. The algorithm does not automatically move on to find
+matches that start at later positions.
+.P
+There are a number of features of PCRE regular expressions that are not
+supported by the alternative matching algorithm. They are as follows:
+.P
+1. Because the algorithm finds all possible matches, the greedy or ungreedy
+nature of repetition quantifiers is not relevant. Greedy and ungreedy
+quantifiers are treated in exactly the same way. However, possessive
+quantifiers can make a difference when what follows could also match what is
+quantified, for example in a pattern like this:
+.sp
+  ^a++\ew!
+.sp
+This pattern matches "aaab!" but not "aaa!", which would be matched by a
+non-possessive quantifier. Similarly, if an atomic group is present, it is
+matched as if it were a standalone pattern at the current point, and the
+longest match is then "locked in" for the rest of the overall pattern.
+.P
+2. When dealing with multiple paths through the tree simultaneously, it is not
+straightforward to keep track of captured substrings for the different matching
+possibilities, and PCRE's implementation of this algorithm does not attempt to
+do this. This means that no captured substrings are available.
+.P
+3. Because no substrings are captured, back references within the pattern are
+not supported, and cause errors if encountered.
+.P
+4. For the same reason, conditional expressions that use a backreference as the
+condition or test for a specific group recursion are not supported.
+.P
+5. Because many paths through the tree may be active, the \eK escape sequence,
+which resets the start of the match when encountered (but may be on some paths
+and not on others), is not supported. It causes an error if encountered.
+.P
+6. Callouts are supported, but the value of the \fIcapture_top\fP field is
+always 1, and the value of the \fIcapture_last\fP field is always -1.
+.P
+7. The \eC escape sequence, which (in the standard algorithm) matches a single
+byte, even in UTF-8 mode, is not supported because the alternative algorithm
+moves through the subject string one character at a time, for all active paths
+through the tree.
+.P
+8. Except for (*FAIL), the backtracking control verbs such as (*PRUNE) are not
+supported. (*FAIL) is supported, and behaves like a failing negative assertion.
+.
+.SH "ADVANTAGES OF THE ALTERNATIVE ALGORITHM"
+.rs
+.sp
+Using the alternative matching algorithm provides the following advantages:
+.P
+1. All possible matches (at a single point in the subject) are automatically
+found, and in particular, the longest match is found. To find more than one
+match using the standard algorithm, you have to do kludgy things with
+callouts.
+.P
+2. Because the alternative algorithm scans the subject string just once, and
+never needs to backtrack, it is possible to pass very long subject strings to
+the matching function in several pieces, checking for partial matching each
+time. The
+.\" HREF
+\fBpcrepartial\fP
+.\"
+documentation gives details of partial matching.
+.
+.
+.SH "DISADVANTAGES OF THE ALTERNATIVE ALGORITHM"
+.rs
+.sp
+The alternative algorithm suffers from a number of disadvantages:
+.P
+1. It is substantially slower than the standard algorithm. This is partly
+because it has to search for all possible matches, but is also because it is
+less susceptible to optimization.
+.P
+2. Capturing parentheses and back references are not supported.
+.P
+3. Although atomic groups are supported, their use does not provide the
+performance advantage that it does for the standard algorithm.

+.TH PCREPARTIAL 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH "PARTIAL MATCHING IN PCRE"
+.rs
+.sp
+In normal use of PCRE, if the subject string that is passed to
+\fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP matches as far as it goes, but is
+too short to match the entire pattern, PCRE_ERROR_NOMATCH is returned. There
+are circumstances where it might be helpful to distinguish this case from other
+cases in which there is no match.
+.P
+Consider, for example, an application where a human is required to type in data
+for a field with specific formatting requirements. An example might be a date
+in the form \fIddmmmyy\fP, defined by this pattern:
+.sp
+  ^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$
+.sp
+If the application sees the user's keystrokes one by one, and can check that
+what has been typed so far is potentially valid, it is able to raise an error
+as soon as a mistake is made, by beeping and not reflecting the character that
+has been typed, for example. This immediate feedback is likely to be a better
+user interface than a check that is delayed until the entire string has been
+entered. Partial matching can also sometimes be useful when the subject string
+is very long and is not all available at once.
+.P
+PCRE supports partial matching by means of the PCRE_PARTIAL_SOFT and
+PCRE_PARTIAL_HARD options, which can be set when calling \fBpcre_exec()\fP or
+\fBpcre_dfa_exec()\fP. For backwards compatibility, PCRE_PARTIAL is a synonym
+for PCRE_PARTIAL_SOFT. The essential difference between the two options is
+whether or not a partial match is preferred to an alternative complete match,
+though the details differ between the two matching functions. If both options
+are set, PCRE_PARTIAL_HARD takes precedence.
+.P
+Setting a partial matching option disables two of PCRE's optimizations. PCRE
+remembers the last literal byte in a pattern, and abandons matching immediately
+if such a byte is not present in the subject string. This optimization cannot
+be used for a subject string that might match only partially. If the pattern
+was studied, PCRE knows the minimum length of a matching string, and does not
+bother to run the matching function on shorter strings. This optimization is
+also disabled for partial matching.
+.
+.
+.SH "PARTIAL MATCHING USING pcre_exec()"
+.rs
+.sp
+A partial match occurs during a call to \fBpcre_exec()\fP whenever the end of
+the subject string is reached successfully, but matching cannot continue
+because more characters are needed. However, at least one character must have
+been matched. (In other words, a partial match can never be an empty string.)
+.P
+If PCRE_PARTIAL_SOFT is set, the partial match is remembered, but matching
+continues as normal, and other alternatives in the pattern are tried. If no
+complete match can be found, \fBpcre_exec()\fP returns PCRE_ERROR_PARTIAL
+instead of PCRE_ERROR_NOMATCH. If there are at least two slots in the offsets
+vector, the first of them is set to the offset of the earliest character that
+was inspected when the partial match was found. For convenience, the second
+offset points to the end of the string so that a substring can easily be
+identified.
+.P
+For the majority of patterns, the first offset identifies the start of the
+partially matched string. However, for patterns that contain lookbehind
+assertions, or \eK, or begin with \eb or \eB, earlier characters have been
+inspected while carrying out the match. For example:
+.sp
+  /(?<=abc)123/
+.sp
+This pattern matches "123", but only if it is preceded by "abc". If the subject
+string is "xyzabc12", the offsets after a partial match are for the substring
+"abc12", because all these characters are needed if another match is tried
+with extra characters added.
+.P
+If there is more than one partial match, the first one that was found provides
+the data that is returned. Consider this pattern:
+.sp
+  /123\ew+X|dogY/
+.sp
+If this is matched against the subject string "abc123dog", both
+alternatives fail to match, but the end of the subject is reached during
+matching, so PCRE_ERROR_PARTIAL is returned instead of PCRE_ERROR_NOMATCH. The
+offsets are set to 3 and 9, identifying "123dog" as the first partial match
+that was found. (In this example, there are two partial matches, because "dog"
+on its own partially matches the second alternative.)
+.P
+If PCRE_PARTIAL_HARD is set for \fBpcre_exec()\fP, it returns
+PCRE_ERROR_PARTIAL as soon as a partial match is found, without continuing to
+search for possible complete matches. The difference between the two options
+can be illustrated by a pattern such as:
+.sp
+  /dog(sbody)?/
+.sp
+This matches either "dog" or "dogsbody", greedily (that is, it prefers the
+longer string if possible). If it is matched against the string "dog" with
+PCRE_PARTIAL_SOFT, it yields a complete match for "dog". However, if
+PCRE_PARTIAL_HARD is set, the result is PCRE_ERROR_PARTIAL. On the other hand,
+if the pattern is made ungreedy the result is different:
+.sp
+  /dog(sbody)??/
+.sp
+In this case the result is always a complete match because \fBpcre_exec()\fP
+finds that first, and it never continues after finding a match. It might be
+easier to follow this explanation by thinking of the two patterns like this:
+.sp
+  /dog(sbody)?/    is the same as  /dogsbody|dog/
+  /dog(sbody)??/   is the same as  /dog|dogsbody/
+.sp
+The second pattern will never match "dogsbody" when \fBpcre_exec()\fP is
+used, because it will always find the shorter match first.
+.
+.
+.SH "PARTIAL MATCHING USING pcre_dfa_exec()"
+.rs
+.sp
+The \fBpcre_dfa_exec()\fP function moves along the subject string character by
+character, without backtracking, searching for all possible matches
+simultaneously. If the end of the subject is reached before the end of the
+pattern, there is the possibility of a partial match, again provided that at
+least one character has matched.
+.P
+When PCRE_PARTIAL_SOFT is set, PCRE_ERROR_PARTIAL is returned only if there
+have been no complete matches. Otherwise, the complete matches are returned.
+However, if PCRE_PARTIAL_HARD is set, a partial match takes precedence over any
+complete matches. The portion of the string that was inspected when the longest
+partial match was found is set as the first matching string, provided there are
+at least two slots in the offsets vector.
+.P
+Because \fBpcre_dfa_exec()\fP always searches for all possible matches, and
+there is no difference between greedy and ungreedy repetition, its behaviour is
+different from \fBpcre_exec\fP when PCRE_PARTIAL_HARD is set. Consider the
+string "dog" matched against the ungreedy pattern shown above:
+.sp
+  /dog(sbody)??/
+.sp
+Whereas \fBpcre_exec()\fP stops as soon as it finds the complete match for
+"dog", \fBpcre_dfa_exec()\fP also finds the partial match for "dogsbody", and
+so returns that when PCRE_PARTIAL_HARD is set.
+.
+.
+.SH "PARTIAL MATCHING AND WORD BOUNDARIES"
+.rs
+.sp
+If a pattern ends with one of sequences \eb or \eB, which test for word
+boundaries, partial matching with PCRE_PARTIAL_SOFT can give counter-intuitive
+results. Consider this pattern:
+.sp
+  /\ebcat\eb/
+.sp
+This matches "cat", provided there is a word boundary at either end. If the
+subject string is "the cat", the comparison of the final "t" with a following
+character cannot take place, so a partial match is found. However,
+\fBpcre_exec()\fP carries on with normal matching, which matches \eb at the end
+of the subject when the last character is a letter, thus finding a complete
+match. The result, therefore, is \fInot\fP PCRE_ERROR_PARTIAL. The same thing
+happens with \fBpcre_dfa_exec()\fP, because it also finds the complete match.
+.P
+Using PCRE_PARTIAL_HARD in this case does yield PCRE_ERROR_PARTIAL, because
+then the partial match takes precedence.
+.
+.
+.SH "FORMERLY RESTRICTED PATTERNS"
+.rs
+.sp
+For releases of PCRE prior to 8.00, because of the way certain internal
+optimizations were implemented in the \fBpcre_exec()\fP function, the
+PCRE_PARTIAL option (predecessor of PCRE_PARTIAL_SOFT) could not be used with
+all patterns. From release 8.00 onwards, the restrictions no longer apply, and
+partial matching with \fBpcre_exec()\fP can be requested for any pattern.
+.P
+Items that were formerly restricted were repeated single characters and
+repeated metasequences. If PCRE_PARTIAL was set for a pattern that did not
+conform to the restrictions, \fBpcre_exec()\fP returned the error code
+PCRE_ERROR_BADPARTIAL (-13). This error code is no longer in use. The
+PCRE_INFO_OKPARTIAL call to \fBpcre_fullinfo()\fP to find out if a compiled
+pattern can be used for partial matching now always returns 1.
+.
+.
+.SH "EXAMPLE OF PARTIAL MATCHING USING PCRETEST"
+.rs
+.sp
+If the escape sequence \eP is present in a \fBpcretest\fP data line, the
+PCRE_PARTIAL_SOFT option is used for the match. Here is a run of \fBpcretest\fP
+that uses the date example quoted above:
+.sp
+    re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+  data> 25jun04\eP
+   0: 25jun04
+   1: jun
+  data> 25dec3\eP
+  Partial match: 23dec3
+  data> 3ju\eP
+  Partial match: 3ju
+  data> 3juj\eP
+  No match
+  data> j\eP
+  No match
+.sp
+The first data string is matched completely, so \fBpcretest\fP shows the
+matched substrings. The remaining four strings do not match the complete
+pattern, but the first two are partial matches. Similar output is obtained
+when \fBpcre_dfa_exec()\fP is used.
+.P
+If the escape sequence \eP is present more than once in a \fBpcretest\fP data
+line, the PCRE_PARTIAL_HARD option is set for the match.
+.
+.
+.SH "MULTI-SEGMENT MATCHING WITH pcre_dfa_exec()"
+.rs
+.sp
+When a partial match has been found using \fBpcre_dfa_exec()\fP, it is possible
+to continue the match by providing additional subject data and calling
+\fBpcre_dfa_exec()\fP again with the same compiled regular expression, this
+time setting the PCRE_DFA_RESTART option. You must pass the same working
+space as before, because this is where details of the previous partial match
+are stored. Here is an example using \fBpcretest\fP, using the \eR escape
+sequence to set the PCRE_DFA_RESTART option (\eD specifies the use of
+\fBpcre_dfa_exec()\fP):
+.sp
+    re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+  data> 23ja\eP\eD
+  Partial match: 23ja
+  data> n05\eR\eD
+   0: n05
+.sp
+The first call has "23ja" as the subject, and requests partial matching; the
+second call has "n05" as the subject for the continued (restarted) match.
+Notice that when the match is complete, only the last part is shown; PCRE does
+not retain the previously partially-matched string. It is up to the calling
+program to do that if it needs to.
+.P
+You can set the PCRE_PARTIAL_SOFT or PCRE_PARTIAL_HARD options with
+PCRE_DFA_RESTART to continue partial matching over multiple segments. This
+facility can be used to pass very long subject strings to
+\fBpcre_dfa_exec()\fP.
+.
+.
+.SH "MULTI-SEGMENT MATCHING WITH pcre_exec()"
+.rs
+.sp
+From release 8.00, \fBpcre_exec()\fP can also be used to do multi-segment
+matching. Unlike \fBpcre_dfa_exec()\fP, it is not possible to restart the
+previous match with a new segment of data. Instead, new data must be added to
+the previous subject string, and the entire match re-run, starting from the
+point where the partial match occurred. Earlier data can be discarded.
+Consider an unanchored pattern that matches dates:
+.sp
+    re> /\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed/
+  data> The date is 23ja\eP
+  Partial match: 23ja
+.sp
+At this stage, an application could discard the text preceding "23ja", add on
+text from the next segment, and call \fBpcre_exec()\fP again. Unlike
+\fBpcre_dfa_exec()\fP, the entire matching string must always be available, and
+the complete matching process occurs for each call, so more memory and more
+processing time is needed.
+.P
+\fBNote:\fP If the pattern contains lookbehind assertions, or \eK, or starts
+with \eb or \eB, the string that is returned for a partial match will include
+characters that precede the partially matched string itself, because these must
+be retained when adding on more characters for a subsequent matching attempt.
+.
+.
+.SH "ISSUES WITH MULTI-SEGMENT MATCHING"
+.rs
+.sp
+Certain types of pattern may give problems with multi-segment matching,
+whichever matching function is used.
+.P
+1. If the pattern contains tests for the beginning or end of a line, you need
+to pass the PCRE_NOTBOL or PCRE_NOTEOL options, as appropriate, when the
+subject string for any call does not contain the beginning or end of a line.
+.P
+2. Lookbehind assertions at the start of a pattern are catered for in the
+offsets that are returned for a partial match. However, in theory, a lookbehind
+assertion later in the pattern could require even earlier characters to be
+inspected, and it might not have been reached when a partial match occurs. This
+is probably an extremely unlikely case; you could guard against it to a certain
+extent by always including extra characters at the start.
+.P
+3. Matching a subject string that is split into multiple segments may not
+always produce exactly the same result as matching over one single long string,
+especially when PCRE_PARTIAL_SOFT is used. The section "Partial Matching and
+Word Boundaries" above describes an issue that arises if the pattern ends with
+\eb or \eB. Another kind of difference may occur when there are multiple
+matching possibilities, because a partial match result is given only when there
+are no completed matches. This means that as soon as the shortest match has
+been found, continuation to a new subject segment is no longer possible.
+Consider again this \fBpcretest\fP example:
+.sp
+    re> /dog(sbody)?/
+  data> dogsb\eP
+   0: dog
+  data> do\eP\eD
+  Partial match: do
+  data> gsb\eR\eP\eD
+   0: g
+  data> dogsbody\eD
+   0: dogsbody
+   1: dog
+.sp
+The first data line passes the string "dogsb" to \fBpcre_exec()\fP, setting the
+PCRE_PARTIAL_SOFT option. Although the string is a partial match for
+"dogsbody", the result is not PCRE_ERROR_PARTIAL, because the shorter string
+"dog" is a complete match. Similarly, when the subject is presented to
+\fBpcre_dfa_exec()\fP in several parts ("do" and "gsb" being the first two) the
+match stops when "dog" has been found, and it is not possible to continue. On
+the other hand, if "dogsbody" is presented as a single string,
+\fBpcre_dfa_exec()\fP finds both matches.
+.P
+Because of these problems, it is probably best to use PCRE_PARTIAL_HARD when
+matching multi-segment data. The example above then behaves differently:
+.sp
+    re> /dog(sbody)?/
+  data> dogsb\eP\eP
+  Partial match: dogsb
+  data> do\eP\eD
+  Partial match: do
+  data> gsb\eR\eP\eP\eD
+  Partial match: gsb
+.sp
+.P
+4. Patterns that contain alternatives at the top level which do not all
+start with the same pattern item may not work as expected when
+PCRE_DFA_RESTART is used with \fBpcre_dfa_exec()\fP. For example, consider this
+pattern:
+.sp
+  1234|3789
+.sp
+If the first part of the subject is "ABC123", a partial match of the first
+alternative is found at offset 3. There is no partial match for the second
+alternative, because such a match does not start at the same point in the
+subject string. Attempting to continue with the string "7890" does not yield a
+match because only those alternatives that match at one point in the subject
+are remembered. The problem arises because the start of the second alternative
+matches within the first alternative. There is no problem with anchored
+patterns or patterns such as:
+.sp
+  1234|ABCD
+.sp
+where no string can be a partial match for both alternatives. This is not a
+problem if \fBpcre_exec()\fP is used, because the entire match has to be rerun
+each time:
+.sp
+    re> /1234|3789/
+  data> ABC123\eP
+  Partial match: 123
+  data> 1237890
+   0: 3789
+.sp
+Of course, instead of using PCRE_DFA_PARTIAL, the same technique of re-running
+the entire match can also be used with \fBpcre_dfa_exec()\fP. Another
+possibility is to work with two buffers. If a partial match at offset \fIn\fP
+in the first buffer is followed by "no match" when PCRE_DFA_RESTART is used on
+the second buffer, you can then try a new match starting at offset \fIn+1\fP in
+the first buffer.

+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH "PCRE REGULAR EXPRESSION DETAILS"
+.rs
+.sp
+The syntax and semantics of the regular expressions that are supported by PCRE
+are described in detail below. There is a quick-reference syntax summary in the
+.\" HREF
+\fBpcresyntax\fP
+.\"
+page. PCRE tries to match Perl syntax and semantics as closely as it can. PCRE
+also supports some alternative regular expression syntax (which does not
+conflict with the Perl syntax) in order to provide some compatibility with
+regular expressions in Python, .NET, and Oniguruma.
+.P
+Perl's regular expressions are described in its own documentation, and
+regular expressions in general are covered in a number of books, some of which
+have copious examples. Jeffrey Friedl's "Mastering Regular Expressions",
+published by O'Reilly, covers regular expressions in great detail. This
+description of PCRE's regular expressions is intended as reference material.
+.P
+The original operation of PCRE was on strings of one-byte characters. However,
+there is now also support for UTF-8 character strings. To use this,
+PCRE must be built to include UTF-8 support, and you must call
+\fBpcre_compile()\fP or \fBpcre_compile2()\fP with the PCRE_UTF8 option. There
+is also a special sequence that can be given at the start of a pattern:
+.sp
+  (*UTF8)
+.sp
+Starting a pattern with this sequence is equivalent to setting the PCRE_UTF8
+option. This feature is not Perl-compatible. How setting UTF-8 mode affects
+pattern matching is mentioned in several places below. There is also a summary
+of UTF-8 features in the
+.\" HTML 
+.\" 
+section on UTF-8 support
+.\"
+in the main
+.\" HREF
+\fBpcre\fP
+.\"
+page.
+.P
+The remainder of this document discusses the patterns that are supported by
+PCRE when its main matching function, \fBpcre_exec()\fP, is used.
+From release 6.0, PCRE offers a second matching function,
+\fBpcre_dfa_exec()\fP, which matches using a different algorithm that is not
+Perl-compatible. Some of the features discussed below are not available when
+\fBpcre_dfa_exec()\fP is used. The advantages and disadvantages of the
+alternative function, and how it differs from the normal function, are
+discussed in the
+.\" HREF
+\fBpcrematching\fP
+.\"
+page.
+.
+.
+.SH "NEWLINE CONVENTIONS"
+.rs
+.sp
+PCRE supports five different conventions for indicating line breaks in
+strings: a single CR (carriage return) character, a single LF (linefeed)
+character, the two-character sequence CRLF, any of the three preceding, or any
+Unicode newline sequence. The
+.\" HREF
+\fBpcreapi\fP
+.\"
+page has
+.\" HTML 
+.\" 
+further discussion
+.\"
+about newlines, and shows how to set the newline convention in the
+\fIoptions\fP arguments for the compiling and matching functions.
+.P
+It is also possible to specify a newline convention by starting a pattern
+string with one of the following five sequences:
+.sp
+  (*CR)        carriage return
+  (*LF)        linefeed
+  (*CRLF)      carriage return, followed by linefeed
+  (*ANYCRLF)   any of the three above
+  (*ANY)       all Unicode newline sequences
+.sp
+These override the default and the options given to \fBpcre_compile()\fP or
+\fBpcre_compile2()\fP. For example, on a Unix system where LF is the default
+newline sequence, the pattern
+.sp
+  (*CR)a.b
+.sp
+changes the convention to CR. That pattern matches "a\enb" because LF is no
+longer a newline. Note that these special settings, which are not
+Perl-compatible, are recognized only at the very start of a pattern, and that
+they must be in upper case. If more than one of them is present, the last one
+is used.
+.P
+The newline convention does not affect what the \eR escape sequence matches. By
+default, this is any Unicode newline sequence, for Perl compatibility. However,
+this can be changed; see the description of \eR in the section entitled
+.\" HTML 
+.\" 
+"Newline sequences"
+.\"
+below. A change of \eR setting can be combined with a change of newline
+convention.
+.
+.
+.SH "CHARACTERS AND METACHARACTERS"
+.rs
+.sp
+A regular expression is a pattern that is matched against a subject string from
+left to right. Most characters stand for themselves in a pattern, and match the
+corresponding characters in the subject. As a trivial example, the pattern
+.sp
+  The quick brown fox
+.sp
+matches a portion of a subject string that is identical to itself. When
+caseless matching is specified (the PCRE_CASELESS option), letters are matched
+independently of case. In UTF-8 mode, PCRE always understands the concept of
+case for characters whose values are less than 128, so caseless matching is
+always possible. For characters with higher values, the concept of case is
+supported if PCRE is compiled with Unicode property support, but not otherwise.
+If you want to use caseless matching for characters 128 and above, you must
+ensure that PCRE is compiled with Unicode property support as well as with
+UTF-8 support.
+.P
+The power of regular expressions comes from the ability to include alternatives
+and repetitions in the pattern. These are encoded in the pattern by the use of
+\fImetacharacters\fP, which do not stand for themselves but instead are
+interpreted in some special way.
+.P
+There are two different sets of metacharacters: those that are recognized
+anywhere in the pattern except within square brackets, and those that are
+recognized within square brackets. Outside square brackets, the metacharacters
+are as follows:
+.sp
+  \e      general escape character with several uses
+  ^      assert start of string (or line, in multiline mode)
+  $      assert end of string (or line, in multiline mode)
+  .      match any character except newline (by default)
+  [      start character class definition
+  |      start of alternative branch
+  (      start subpattern
+  )      end subpattern
+  ?      extends the meaning of (
+         also 0 or 1 quantifier
+         also quantifier minimizer
+  *      0 or more quantifier
+  +      1 or more quantifier
+         also "possessive quantifier"
+  {      start min/max quantifier
+.sp
+Part of a pattern that is in square brackets is called a "character class". In
+a character class the only metacharacters are:
+.sp
+  \e      general escape character
+  ^      negate the class, but only if the first character
+  -      indicates character range
+.\" JOIN
+  [      POSIX character class (only if followed by POSIX
+           syntax)
+  ]      terminates the character class
+.sp
+The following sections describe the use of each of the metacharacters.
+.
+.
+.SH BACKSLASH
+.rs
+.sp
+The backslash character has several uses. Firstly, if it is followed by a
+non-alphanumeric character, it takes away any special meaning that character
+may have. This use of backslash as an escape character applies both inside and
+outside character classes.
+.P
+For example, if you want to match a * character, you write \e* in the pattern.
+This escaping action applies whether or not the following character would
+otherwise be interpreted as a metacharacter, so it is always safe to precede a
+non-alphanumeric with backslash to specify that it stands for itself. In
+particular, if you want to match a backslash, you write \e\e.
+.P
+If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the
+pattern (other than in a character class) and characters between a # outside
+a character class and the next newline are ignored. An escaping backslash can
+be used to include a whitespace or # character as part of the pattern.
+.P
+If you want to remove the special meaning from a sequence of characters, you
+can do so by putting them between \eQ and \eE. This is different from Perl in
+that $ and @ are handled as literals in \eQ...\eE sequences in PCRE, whereas in
+Perl, $ and @ cause variable interpolation. Note the following examples:
+.sp
+  Pattern            PCRE matches   Perl matches
+.sp
+.\" JOIN
+  \eQabc$xyz\eE        abc$xyz        abc followed by the
+                                      contents of $xyz
+  \eQabc\e$xyz\eE       abc\e$xyz       abc\e$xyz
+  \eQabc\eE\e$\eQxyz\eE   abc$xyz        abc$xyz
+.sp
+The \eQ...\eE sequence is recognized both inside and outside character classes.
+.
+.
+.\" HTML 
+.SS "Non-printing characters"
+.rs
+.sp
+A second use of backslash provides a way of encoding non-printing characters
+in patterns in a visible manner. There is no restriction on the appearance of
+non-printing characters, apart from the binary zero that terminates a pattern,
+but when a pattern is being prepared by text editing, it is often easier to use
+one of the following escape sequences than the binary character it represents:
+.sp
+  \ea        alarm, that is, the BEL character (hex 07)
+  \ecx       "control-x", where x is any character
+  \ee        escape (hex 1B)
+  \ef        formfeed (hex 0C)
+  \en        linefeed (hex 0A)
+  \er        carriage return (hex 0D)
+  \et        tab (hex 09)
+  \eddd      character with octal code ddd, or backreference
+  \exhh      character with hex code hh
+  \ex{hhh..} character with hex code hhh..
+.sp
+The precise effect of \ecx is as follows: if x is a lower case letter, it
+is converted to upper case. Then bit 6 of the character (hex 40) is inverted.
+Thus \ecz becomes hex 1A, but \ec{ becomes hex 3B, while \ec; becomes hex
+7B.
+.P
+After \ex, from zero to two hexadecimal digits are read (letters can be in
+upper or lower case). Any number of hexadecimal digits may appear between \ex{
+and }, but the value of the character code must be less than 256 in non-UTF-8
+mode, and less than 2**31 in UTF-8 mode. That is, the maximum value in
+hexadecimal is 7FFFFFFF. Note that this is bigger than the largest Unicode code
+point, which is 10FFFF.
+.P
+If characters other than hexadecimal digits appear between \ex{ and }, or if
+there is no terminating }, this form of escape is not recognized. Instead, the
+initial \ex will be interpreted as a basic hexadecimal escape, with no
+following digits, giving a character whose value is zero.
+.P
+Characters whose value is less than 256 can be defined by either of the two
+syntaxes for \ex. There is no difference in the way they are handled. For
+example, \exdc is exactly the same as \ex{dc}.
+.P
+After \e0 up to two further octal digits are read. If there are fewer than two
+digits, just those that are present are used. Thus the sequence \e0\ex\e07
+specifies two binary zeros followed by a BEL character (code value 7). Make
+sure you supply two digits after the initial zero if the pattern character that
+follows is itself an octal digit.
+.P
+The handling of a backslash followed by a digit other than 0 is complicated.
+Outside a character class, PCRE reads it and any following digits as a decimal
+number. If the number is less than 10, or if there have been at least that many
+previous capturing left parentheses in the expression, the entire sequence is
+taken as a \fIback reference\fP. A description of how this works is given
+.\" HTML 
+.\" 
+later,
+.\"
+following the discussion of
+.\" HTML 
+.\" 
+parenthesized subpatterns.
+.\"
+.P
+Inside a character class, or if the decimal number is greater than 9 and there
+have not been that many capturing subpatterns, PCRE re-reads up to three octal
+digits following the backslash, and uses them to generate a data character. Any
+subsequent digits stand for themselves. In non-UTF-8 mode, the value of a
+character specified in octal must be less than \e400. In UTF-8 mode, values up
+to \e777 are permitted. For example:
+.sp
+  \e040   is another way of writing a space
+.\" JOIN
+  \e40    is the same, provided there are fewer than 40
+            previous capturing subpatterns
+  \e7     is always a back reference
+.\" JOIN
+  \e11    might be a back reference, or another way of
+            writing a tab
+  \e011   is always a tab
+  \e0113  is a tab followed by the character "3"
+.\" JOIN
+  \e113   might be a back reference, otherwise the
+            character with octal code 113
+.\" JOIN
+  \e377   might be a back reference, otherwise
+            the byte consisting entirely of 1 bits
+.\" JOIN
+  \e81    is either a back reference, or a binary zero
+            followed by the two characters "8" and "1"
+.sp
+Note that octal values of 100 or greater must not be introduced by a leading
+zero, because no more than three octal digits are ever read.
+.P
+All the sequences that define a single character value can be used both inside
+and outside character classes. In addition, inside a character class, the
+sequence \eb is interpreted as the backspace character (hex 08), and the
+sequences \eR and \eX are interpreted as the characters "R" and "X",
+respectively. Outside a character class, these sequences have different
+meanings
+.\" HTML 
+.\" 
+(see below).
+.\"
+.
+.
+.SS "Absolute and relative back references"
+.rs
+.sp
+The sequence \eg followed by an unsigned or a negative number, optionally
+enclosed in braces, is an absolute or relative back reference. A named back
+reference can be coded as \eg{name}. Back references are discussed
+.\" HTML 
+.\" 
+later,
+.\"
+following the discussion of
+.\" HTML 
+.\" 
+parenthesized subpatterns.
+.\"
+.
+.
+.SS "Absolute and relative subroutine calls"
+.rs
+.sp
+For compatibility with Oniguruma, the non-Perl syntax \eg followed by a name or
+a number enclosed either in angle brackets or single quotes, is an alternative
+syntax for referencing a subpattern as a "subroutine". Details are discussed
+.\" HTML 
+.\" 
+later.
+.\"
+Note that \eg{...} (Perl syntax) and \eg<...> (Oniguruma syntax) are \fInot\fP
+synonymous. The former is a back reference; the latter is a
+.\" HTML 
+.\" 
+subroutine
+.\"
+call.
+.
+.
+.SS "Generic character types"
+.rs
+.sp
+Another use of backslash is for specifying generic character types. The
+following are always recognized:
+.sp
+  \ed     any decimal digit
+  \eD     any character that is not a decimal digit
+  \eh     any horizontal whitespace character
+  \eH     any character that is not a horizontal whitespace character
+  \es     any whitespace character
+  \eS     any character that is not a whitespace character
+  \ev     any vertical whitespace character
+  \eV     any character that is not a vertical whitespace character
+  \ew     any "word" character
+  \eW     any "non-word" character
+.sp
+Each pair of escape sequences partitions the complete set of characters into
+two disjoint sets. Any given character matches one, and only one, of each pair.
+.P
+These character type sequences can appear both inside and outside character
+classes. They each match one character of the appropriate type. If the current
+matching point is at the end of the subject string, all of them fail, since
+there is no character to match.
+.P
+For compatibility with Perl, \es does not match the VT character (code 11).
+This makes it different from the the POSIX "space" class. The \es characters
+are HT (9), LF (10), FF (12), CR (13), and space (32). If "use locale;" is
+included in a Perl script, \es may match the VT character. In PCRE, it never
+does.
+.P
+In UTF-8 mode, characters with values greater than 128 never match \ed, \es, or
+\ew, and always match \eD, \eS, and \eW. This is true even when Unicode
+character property support is available. These sequences retain their original
+meanings from before UTF-8 support was available, mainly for efficiency
+reasons. Note that this also affects \eb, because it is defined in terms of \ew
+and \eW.
+.P
+The sequences \eh, \eH, \ev, and \eV are Perl 5.10 features. In contrast to the
+other sequences, these do match certain high-valued codepoints in UTF-8 mode.
+The horizontal space characters are:
+.sp
+  U+0009     Horizontal tab
+  U+0020     Space
+  U+00A0     Non-break space
+  U+1680     Ogham space mark
+  U+180E     Mongolian vowel separator
+  U+2000     En quad
+  U+2001     Em quad
+  U+2002     En space
+  U+2003     Em space
+  U+2004     Three-per-em space
+  U+2005     Four-per-em space
+  U+2006     Six-per-em space
+  U+2007     Figure space
+  U+2008     Punctuation space
+  U+2009     Thin space
+  U+200A     Hair space
+  U+202F     Narrow no-break space
+  U+205F     Medium mathematical space
+  U+3000     Ideographic space
+.sp
+The vertical space characters are:
+.sp
+  U+000A     Linefeed
+  U+000B     Vertical tab
+  U+000C     Formfeed
+  U+000D     Carriage return
+  U+0085     Next line
+  U+2028     Line separator
+  U+2029     Paragraph separator
+.P
+A "word" character is an underscore or any character less than 256 that is a
+letter or digit. The definition of letters and digits is controlled by PCRE's
+low-valued character tables, and may vary if locale-specific matching is taking
+place (see
+.\" HTML 
+.\" 
+"Locale support"
+.\"
+in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+page). For example, in a French locale such as "fr_FR" in Unix-like systems,
+or "french" in Windows, some character codes greater than 128 are used for
+accented letters, and these are matched by \ew. The use of locales with Unicode
+is discouraged.
+.
+.
+.\" HTML 
+.SS "Newline sequences"
+.rs
+.sp
+Outside a character class, by default, the escape sequence \eR matches any
+Unicode newline sequence. This is a Perl 5.10 feature. In non-UTF-8 mode \eR is
+equivalent to the following:
+.sp
+  (?>\er\en|\en|\ex0b|\ef|\er|\ex85)
+.sp
+This is an example of an "atomic group", details of which are given
+.\" HTML 
+.\" 
+below.
+.\"
+This particular group matches either the two-character sequence CR followed by
+LF, or one of the single characters LF (linefeed, U+000A), VT (vertical tab,
+U+000B), FF (formfeed, U+000C), CR (carriage return, U+000D), or NEL (next
+line, U+0085). The two-character sequence is treated as a single unit that
+cannot be split.
+.P
+In UTF-8 mode, two additional characters whose codepoints are greater than 255
+are added: LS (line separator, U+2028) and PS (paragraph separator, U+2029).
+Unicode character property support is not needed for these characters to be
+recognized.
+.P
+It is possible to restrict \eR to match only CR, LF, or CRLF (instead of the
+complete set of Unicode line endings) by setting the option PCRE_BSR_ANYCRLF
+either at compile time or when the pattern is matched. (BSR is an abbrevation
+for "backslash R".) This can be made the default when PCRE is built; if this is
+the case, the other behaviour can be requested via the PCRE_BSR_UNICODE option.
+It is also possible to specify these settings by starting a pattern string with
+one of the following sequences:
+.sp
+  (*BSR_ANYCRLF)   CR, LF, or CRLF only
+  (*BSR_UNICODE)   any Unicode newline sequence
+.sp
+These override the default and the options given to \fBpcre_compile()\fP or
+\fBpcre_compile2()\fP, but they can be overridden by options given to
+\fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP. Note that these special settings,
+which are not Perl-compatible, are recognized only at the very start of a
+pattern, and that they must be in upper case. If more than one of them is
+present, the last one is used. They can be combined with a change of newline
+convention, for example, a pattern can start with:
+.sp
+  (*ANY)(*BSR_ANYCRLF)
+.sp
+Inside a character class, \eR matches the letter "R".
+.
+.
+.\" HTML 
+.SS Unicode character properties
+.rs
+.sp
+When PCRE is built with Unicode character property support, three additional
+escape sequences that match characters with specific properties are available.
+When not in UTF-8 mode, these sequences are of course limited to testing
+characters whose codepoints are less than 256, but they do work in this mode.
+The extra escape sequences are:
+.sp
+  \ep{\fIxx\fP}   a character with the \fIxx\fP property
+  \eP{\fIxx\fP}   a character without the \fIxx\fP property
+  \eX       an extended Unicode sequence
+.sp
+The property names represented by \fIxx\fP above are limited to the Unicode
+script names, the general category properties, and "Any", which matches any

+.P
+Each character has exactly one general category property, specified by a
+two-letter abbreviation. For compatibility with Perl, negation can be specified
+by including a circumflex between the opening brace and the property name. For
+example, \ep{^Lu} is the same as \eP{Lu}.
+.P
+If only one letter is specified with \ep or \eP, it includes all the general
+category properties that start with that letter. In this case, in the absence
+of negation, the curly brackets in the escape sequence are optional; these two
+examples have the same effect:
+.sp
+  \ep{L}
+  \epL

+  Z     Separator
+  Zl    Line separator
+  Zp    Paragraph separator
+  Zs    Space separator
+.sp
+The special property L& is also supported: it matches a character that has
+the Lu, Ll, or Lt property, in other words, a letter that is not classified as
+a modifier or "other".
+.P
+The Cs (Surrogate) property applies only to characters in the range U+D800 to
+U+DFFF. Such characters are not valid in UTF-8 strings (see RFC 3629) and so
+cannot be tested by PCRE, unless UTF-8 validity checking has been turned off
+(see the discussion of PCRE_NO_UTF8_CHECK in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+page). Perl does not support the Cs property.
+.P
+The long synonyms for property names that Perl supports (such as \ep{Letter})
+are not supported by PCRE, nor is it permitted to prefix any of these
+properties with "Is".
+.P
+No character that is in the Unicode table has the Cn (unassigned) property.
+Instead, this property is assumed for any code point that is not in the
+Unicode table.
+.P
+Specifying caseless matching does not affect these escape sequences. For
+example, \ep{Lu} always matches only upper case letters.
+.P
+The \eX escape matches any number of Unicode characters that form an extended
+Unicode sequence. \eX is equivalent to
+.sp
+  (?>\ePM\epM*)
+.sp
+That is, it matches a character without the "mark" property, followed by zero
+or more characters with the "mark" property, and treats the sequence as an
+atomic group
+.\" HTML 
+.\" 
+(see below).
+.\"
+Characters with the "mark" property are typically accents that affect the
+preceding character. None of them have codepoints less than 256, so in
+non-UTF-8 mode \eX matches any one character.
+.P
+Matching characters by Unicode property is not fast, because PCRE has to search
+a structure that contains data for over fifteen thousand characters. That is
+why the traditional escape sequences such as \ed and \ew do not use Unicode
+properties in PCRE.
+.
+.
+.\" HTML 
+.SS "Resetting the match start"
+.rs
+.sp
+The escape sequence \eK, which is a Perl 5.10 feature, causes any previously
+matched characters not to be included in the final matched sequence. For
+example, the pattern:
+.sp
+  foo\eKbar
+.sp
+matches "foobar", but reports that it has matched "bar". This feature is
+similar to a lookbehind assertion
+.\" HTML 
+.\" 
+(described below).
+.\"
+However, in this case, the part of the subject before the real match does not
+have to be of fixed length, as lookbehind assertions do. The use of \eK does
+not interfere with the setting of
+.\" HTML 
+.\" 
+captured substrings.
+.\"
+For example, when the pattern
+.sp
+  (foo)\eKbar
+.sp
+matches "foobar", the first substring is still set to "foo".
+.
+.
+.\" HTML 
+.SS "Simple assertions"
+.rs
+.sp
+The final use of backslash is for certain simple assertions. An assertion
+specifies a condition that has to be met at a particular point in a match,
+without consuming any characters from the subject string. The use of
+subpatterns for more complicated assertions is described
+.\" HTML 
+.\" 
+below.
+.\"
+The backslashed assertions are:
+.sp
+  \eb     matches at a word boundary
+  \eB     matches when not at a word boundary
+  \eA     matches at the start of the subject
+  \eZ     matches at the end of the subject
+          also matches before a newline at the end of the subject
+  \ez     matches only at the end of the subject
+  \eG     matches at the first matching position in the subject
+.sp
+These assertions may not appear in character classes (but note that \eb has a
+different meaning, namely the backspace character, inside a character class).
+.P
+A word boundary is a position in the subject string where the current character
+and the previous character do not both match \ew or \eW (i.e. one matches
+\ew and the other matches \eW), or the start or end of the string if the
+first or last character matches \ew, respectively. Neither PCRE nor Perl has a
+separte "start of word" or "end of word" metasequence. However, whatever
+follows \eb normally determines which it is. For example, the fragment
+\eba matches "a" at the start of a word.
+.P
+The \eA, \eZ, and \ez assertions differ from the traditional circumflex and
+dollar (described in the next section) in that they only ever match at the very
+start and end of the subject string, whatever options are set. Thus, they are
+independent of multiline mode. These three assertions are not affected by the
+PCRE_NOTBOL or PCRE_NOTEOL options, which affect only the behaviour of the
+circumflex and dollar metacharacters. However, if the \fIstartoffset\fP
+argument of \fBpcre_exec()\fP is non-zero, indicating that matching is to start
+at a point other than the beginning of the subject, \eA can never match. The
+difference between \eZ and \ez is that \eZ matches before a newline at the end
+of the string as well as at the very end, whereas \ez matches only at the end.
+.P
+The \eG assertion is true only when the current matching position is at the
+start point of the match, as specified by the \fIstartoffset\fP argument of
+\fBpcre_exec()\fP. It differs from \eA when the value of \fIstartoffset\fP is
+non-zero. By calling \fBpcre_exec()\fP multiple times with appropriate
+arguments, you can mimic Perl's /g option, and it is in this kind of
+implementation where \eG can be useful.
+.P
+Note, however, that PCRE's interpretation of \eG, as the start of the current
+match, is subtly different from Perl's, which defines it as the end of the
+previous match. In Perl, these can be different when the previously matched
+string was empty. Because PCRE does just one match at a time, it cannot
+reproduce this behaviour.
+.P
+If all the alternatives of a pattern begin with \eG, the expression is anchored
+to the starting match position, and the "anchored" flag is set in the compiled
+regular expression.
+.
+.
+.SH "CIRCUMFLEX AND DOLLAR"
+.rs
+.sp
+Outside a character class, in the default matching mode, the circumflex
+character is an assertion that is true only if the current matching point is
+at the start of the subject string. If the \fIstartoffset\fP argument of
+\fBpcre_exec()\fP is non-zero, circumflex can never match if the PCRE_MULTILINE
+option is unset. Inside a character class, circumflex has an entirely different
+meaning
+.\" HTML 
+.\" 
+(see below).
+.\"
+.P
+Circumflex need not be the first character of the pattern if a number of
+alternatives are involved, but it should be the first thing in each alternative
+in which it appears if the pattern is ever to match that branch. If all
+possible alternatives start with a circumflex, that is, if the pattern is
+constrained to match only at the start of the subject, it is said to be an
+"anchored" pattern. (There are also other constructs that can cause a pattern
+to be anchored.)
+.P
+A dollar character is an assertion that is true only if the current matching
+point is at the end of the subject string, or immediately before a newline
+at the end of the string (by default). Dollar need not be the last character of
+the pattern if a number of alternatives are involved, but it should be the last
+item in any branch in which it appears. Dollar has no special meaning in a
+character class.
+.P
+The meaning of dollar can be changed so that it matches only at the very end of
+the string, by setting the PCRE_DOLLAR_ENDONLY option at compile time. This
+does not affect the \eZ assertion.
+.P
+The meanings of the circumflex and dollar characters are changed if the
+PCRE_MULTILINE option is set. When this is the case, a circumflex matches
+immediately after internal newlines as well as at the start of the subject
+string. It does not match after a newline that ends the string. A dollar
+matches before any newlines in the string, as well as at the very end, when
+PCRE_MULTILINE is set. When newline is specified as the two-character
+sequence CRLF, isolated CR and LF characters do not indicate newlines.
+.P
+For example, the pattern /^abc$/ matches the subject string "def\enabc" (where
+\en represents a newline) in multiline mode, but not otherwise. Consequently,
+patterns that are anchored in single line mode because all branches start with
+^ are not anchored in multiline mode, and a match for circumflex is possible
+when the \fIstartoffset\fP argument of \fBpcre_exec()\fP is non-zero. The
+PCRE_DOLLAR_ENDONLY option is ignored if PCRE_MULTILINE is set.
+.P
+Note that the sequences \eA, \eZ, and \ez can be used to match the start and
+end of the subject in both modes, and if all branches of a pattern start with
+\eA it is always anchored, whether or not PCRE_MULTILINE is set.
+.
+.
+.SH "FULL STOP (PERIOD, DOT)"
+.rs
+.sp
+Outside a character class, a dot in the pattern matches any one character in
+the subject string except (by default) a character that signifies the end of a
+line. In UTF-8 mode, the matched character may be more than one byte long.
+.P
+When a line ending is defined as a single character, dot never matches that
+character; when the two-character sequence CRLF is used, dot does not match CR
+if it is immediately followed by LF, but otherwise it matches all characters
+(including isolated CRs and LFs). When any Unicode line endings are being
+recognized, dot does not match CR or LF or any of the other line ending
+characters.
+.P
+The behaviour of dot with regard to newlines can be changed. If the PCRE_DOTALL
+option is set, a dot matches any one character, without exception. If the
+two-character sequence CRLF is present in the subject string, it takes two dots
+to match it.
+.P
+The handling of dot is entirely independent of the handling of circumflex and
+dollar, the only relationship being that they both involve newlines. Dot has no
+special meaning in a character class.
+.
+.
+.SH "MATCHING A SINGLE BYTE"
+.rs
+.sp
+Outside a character class, the escape sequence \eC matches any one byte, both
+in and out of UTF-8 mode. Unlike a dot, it always matches any line-ending
+characters. The feature is provided in Perl in order to match individual bytes
+in UTF-8 mode. Because it breaks up UTF-8 characters into individual bytes,
+what remains in the string may be a malformed UTF-8 string. For this reason,
+the \eC escape sequence is best avoided.
+.P
+PCRE does not allow \eC to appear in lookbehind assertions
+.\" HTML 
+.\" 
+(described below),
+.\"
+because in UTF-8 mode this would make it impossible to calculate the length of
+the lookbehind.
+.
+.
+.\" HTML 
+.SH "SQUARE BRACKETS AND CHARACTER CLASSES"
+.rs
+.sp
+An opening square bracket introduces a character class, terminated by a closing
+square bracket. A closing square bracket on its own is not special by default.
+However, if the PCRE_JAVASCRIPT_COMPAT option is set, a lone closing square
+bracket causes a compile-time error. If a closing square bracket is required as
+a member of the class, it should be the first data character in the class
+(after an initial circumflex, if present) or escaped with a backslash.
+.P
+A character class matches a single character in the subject. In UTF-8 mode, the
+character may be more than one byte long. A matched character must be in the
+set of characters defined by the class, unless the first character in the class
+definition is a circumflex, in which case the subject character must not be in
+the set defined by the class. If a circumflex is actually required as a member
+of the class, ensure it is not the first character, or escape it with a
+backslash.
+.P
+For example, the character class [aeiou] matches any lower case vowel, while
+[^aeiou] matches any character that is not a lower case vowel. Note that a
+circumflex is just a convenient notation for specifying the characters that
+are in the class by enumerating those that are not. A class that starts with a
+circumflex is not an assertion; it still consumes a character from the subject
+string, and therefore it fails if the current pointer is at the end of the
+string.
+.P
+In UTF-8 mode, characters with values greater than 255 can be included in a
+class as a literal string of bytes, or by using the \ex{ escaping mechanism.
+.P
+When caseless matching is set, any letters in a class represent both their
+upper case and lower case versions, so for example, a caseless [aeiou] matches
+"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
+caseful version would. In UTF-8 mode, PCRE always understands the concept of
+case for characters whose values are less than 128, so caseless matching is
+always possible. For characters with higher values, the concept of case is
+supported if PCRE is compiled with Unicode property support, but not otherwise.
+If you want to use caseless matching in UTF8-mode for characters 128 and above,
+you must ensure that PCRE is compiled with Unicode property support as well as
+with UTF-8 support.
+.P
+Characters that might indicate line breaks are never treated in any special way
+when matching character classes, whatever line-ending sequence is in use, and
+whatever setting of the PCRE_DOTALL and PCRE_MULTILINE options is used. A class
+such as [^a] always matches one of these characters.
+.P
+The minus (hyphen) character can be used to specify a range of characters in a
+character class. For example, [d-m] matches any letter between d and m,
+inclusive. If a minus character is required in a class, it must be escaped with
+a backslash or appear in a position where it cannot be interpreted as
+indicating a range, typically as the first or last character in the class.
+.P
+It is not possible to have the literal character "]" as the end character of a
+range. A pattern such as [W-]46] is interpreted as a class of two characters
+("W" and "-") followed by a literal string "46]", so it would match "W46]" or
+"-46]". However, if the "]" is escaped with a backslash it is interpreted as
+the end of range, so [W-\e]46] is interpreted as a class containing a range
+followed by two other characters. The octal or hexadecimal representation of
+"]" can also be used to end a range.
+.P
+Ranges operate in the collating sequence of character values. They can also be
+used for characters specified numerically, for example [\e000-\e037]. In UTF-8
+mode, ranges can include characters whose values are greater than 255, for
+example [\ex{100}-\ex{2ff}].
+.P
+If a range that includes letters is used when caseless matching is set, it
+matches the letters in either case. For example, [W-c] is equivalent to
+[][\e\e^_`wxyzabc], matched caselessly, and in non-UTF-8 mode, if character
+tables for a French locale are in use, [\exc8-\excb] matches accented E
+characters in both cases. In UTF-8 mode, PCRE supports the concept of case for
+characters with values greater than 128 only when it is compiled with Unicode
+property support.
+.P
+The character types \ed, \eD, \ep, \eP, \es, \eS, \ew, and \eW may also appear
+in a character class, and add the characters that they match to the class. For
+example, [\edABCDEF] matches any hexadecimal digit. A circumflex can
+conveniently be used with the upper case character types to specify a more
+restricted set of characters than the matching lower case type. For example,
+the class [^\eW_] matches any letter or digit, but not underscore.
+.P
+The only metacharacters that are recognized in character classes are backslash,
+hyphen (only where it can be interpreted as specifying a range), circumflex
+(only at the start), opening square bracket (only when it can be interpreted as
+introducing a POSIX class name - see the next section), and the terminating
+closing square bracket. However, escaping other non-alphanumeric characters
+does no harm.
+.
+.
+.SH "POSIX CHARACTER CLASSES"
+.rs
+.sp
+Perl supports the POSIX notation for character classes. This uses names
+enclosed by [: and :] within the enclosing square brackets. PCRE also supports
+this notation. For example,
+.sp
+  [01[:alpha:]%]
+.sp
+matches "0", "1", any alphabetic character, or "%". The supported class names
+are
+.sp
+  alnum    letters and digits
+  alpha    letters
+  ascii    character codes 0 - 127
+  blank    space or tab only
+  cntrl    control characters
+  digit    decimal digits (same as \ed)
+  graph    printing characters, excluding space
+  lower    lower case letters
+  print    printing characters, including space
+  punct    printing characters, excluding letters and digits
+  space    white space (not quite the same as \es)
+  upper    upper case letters
+  word     "word" characters (same as \ew)
+  xdigit   hexadecimal digits
+.sp
+The "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13), and
+space (32). Notice that this list includes the VT character (code 11). This
+makes "space" different to \es, which does not include VT (for Perl
+compatibility).
+.P
+The name "word" is a Perl extension, and "blank" is a GNU extension from Perl
+5.8. Another Perl extension is negation, which is indicated by a ^ character
+after the colon. For example,
+.sp
+  [12[:^digit:]]
+.sp
+matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the POSIX
+syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
+supported, and an error is given if they are encountered.
+.P
+In UTF-8 mode, characters with values greater than 128 do not match any of
+the POSIX character classes.
+.
+.
+.SH "VERTICAL BAR"
+.rs
+.sp
+Vertical bar characters are used to separate alternative patterns. For example,
+the pattern
+.sp
+  gilbert|sullivan
+.sp
+matches either "gilbert" or "sullivan". Any number of alternatives may appear,
+and an empty alternative is permitted (matching the empty string). The matching
+process tries each alternative in turn, from left to right, and the first one
+that succeeds is used. If the alternatives are within a subpattern
+.\" HTML

+"succeeds" means matching the rest of the main pattern as well as the
+alternative in the subpattern.
+.
+.
+.SH "INTERNAL OPTION SETTING"
+.rs
+.sp
+The settings of the PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and
+PCRE_EXTENDED options (which are Perl-compatible) can be changed from within
+the pattern by a sequence of Perl option letters enclosed between "(?" and ")".
+The option letters are
+.sp
+  i  for PCRE_CASELESS
+  m  for PCRE_MULTILINE
+  s  for PCRE_DOTALL
+  x  for PCRE_EXTENDED
+.sp
+For example, (?im) sets caseless, multiline matching. It is also possible to
+unset these options by preceding the letter with a hyphen, and a combined
+setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and
+PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also
+permitted. If a letter appears both before and after the hyphen, the option is
+unset.
+.P
+The PCRE-specific options PCRE_DUPNAMES, PCRE_UNGREEDY, and PCRE_EXTRA can be
+changed in the same way as the Perl-compatible options by using the characters
+J, U and X respectively.
+.P
+When one of these option changes occurs at top level (that is, not inside
+subpattern parentheses), the change applies to the remainder of the pattern
+that follows. If the change is placed right at the start of a pattern, PCRE
+extracts it into the global options (and it will therefore show up in data
+extracted by the \fBpcre_fullinfo()\fP function).
+.P
+An option change within a subpattern (see below for a description of
+subpatterns) affects only that part of the current pattern that follows it, so
+.sp
+  (a(?i)b)c
+.sp
+matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used).
+By this means, options can be made to have different settings in different
+parts of the pattern. Any changes made in one alternative do carry on
+into subsequent branches within the same subpattern. For example,
+.sp
+  (a(?i)b|c)
+.sp
+matches "ab", "aB", "c", and "C", even though when matching "C" the first
+branch is abandoned before the option setting. This is because the effects of
+option settings happen at compile time. There would be some very weird
+behaviour otherwise.
+.P
+\fBNote:\fP There are other PCRE-specific options that can be set by the
+application when the compile or match functions are called. In some cases the
+pattern can contain special leading sequences such as (*CRLF) to override what
+the application has set or what has been defaulted. Details are given in the
+section entitled
+.\" HTML 
+.\" 
+"Newline sequences"
+.\"
+above. There is also the (*UTF8) leading sequence that can be used to set UTF-8
+mode; this is equivalent to setting the PCRE_UTF8 option.
+.
+.
+.\" HTML 
+.SH SUBPATTERNS
+.rs
+.sp
+Subpatterns are delimited by parentheses (round brackets), which can be nested.
+Turning part of a pattern into a subpattern does two things:
+.sp
+1. It localizes a set of alternatives. For example, the pattern
+.sp
+  cat(aract|erpillar|)
+.sp
+matches one of the words "cat", "cataract", or "caterpillar". Without the
+parentheses, it would match "cataract", "erpillar" or an empty string.
+.sp
+2. It sets up the subpattern as a capturing subpattern. This means that, when
+the whole pattern matches, that portion of the subject string that matched the
+subpattern is passed back to the caller via the \fIovector\fP argument of
+\fBpcre_exec()\fP. Opening parentheses are counted from left to right (starting
+from 1) to obtain numbers for the capturing subpatterns.
+.P
+For example, if the string "the red king" is matched against the pattern
+.sp
+  the ((red|white) (king|queen))
+.sp
+the captured substrings are "red king", "red", and "king", and are numbered 1,
+2, and 3, respectively.
+.P
+The fact that plain parentheses fulfil two functions is not always helpful.
+There are often times when a grouping subpattern is required without a
+capturing requirement. If an opening parenthesis is followed by a question mark
+and a colon, the subpattern does not do any capturing, and is not counted when
+computing the number of any subsequent capturing subpatterns. For example, if
+the string "the white queen" is matched against the pattern
+.sp
+  the ((?:red|white) (king|queen))
+.sp
+the captured substrings are "white queen" and "queen", and are numbered 1 and
+2. The maximum number of capturing subpatterns is 65535.
+.P
+As a convenient shorthand, if any option settings are required at the start of
+a non-capturing subpattern, the option letters may appear between the "?" and
+the ":". Thus the two patterns
+.sp
+  (?i:saturday|sunday)
+  (?:(?i)saturday|sunday)
+.sp
+match exactly the same set of strings. Because alternative branches are tried
+from left to right, and options are not reset until the end of the subpattern
+is reached, an option setting in one branch does affect subsequent branches, so
+the above patterns match "SUNDAY" as well as "Saturday".
+.
+.
+.\" HTML 
+.SH "DUPLICATE SUBPATTERN NUMBERS"
+.rs
+.sp
+Perl 5.10 introduced a feature whereby each alternative in a subpattern uses
+the same numbers for its capturing parentheses. Such a subpattern starts with
+(?| and is itself a non-capturing subpattern. For example, consider this
+pattern:
+.sp
+  (?|(Sat)ur|(Sun))day
+.sp
+Because the two alternatives are inside a (?| group, both sets of capturing
+parentheses are numbered one. Thus, when the pattern matches, you can look
+at captured substring number one, whichever alternative matched. This construct
+is useful when you want to capture part, but not all, of one of a number of
+alternatives. Inside a (?| group, parentheses are numbered as usual, but the
+number is reset at the start of each branch. The numbers of any capturing
+buffers that follow the subpattern start after the highest number used in any
+branch. The following example is taken from the Perl documentation.
+The numbers underneath show in which buffer the captured content will be
+stored.
+.sp

+.P
+An alternative approach to using this "branch reset" feature is to use
+duplicate named subpatterns, as described in the next section.
+.
+.
+.SH "NAMED SUBPATTERNS"
+.rs
+.sp
+Identifying capturing parentheses by number is simple, but it can be very hard
+to keep track of the numbers in complicated regular expressions. Furthermore,
+if an expression is modified, the numbers may change. To help with this
+difficulty, PCRE supports the naming of subpatterns. This feature was not
+added to Perl until release 5.10. Python had the feature earlier, and PCRE
+introduced it at release 4.0, using the Python syntax. PCRE now supports both
+the Perl and the Python syntax. Perl allows identically numbered subpatterns to
+have different names, but PCRE does not.
+.P
+In PCRE, a subpattern can be named in one of three ways: (?...) or
+(?'name'...) as in Perl, or (?P...) as in Python. References to capturing
+parentheses from other parts of the pattern, such as
+.\" HTML 
+.\" 
+backreferences,
+.\"
+.\" HTML 
+.\" 
+recursion,
+.\"
+and
+.\" HTML 
+.\" 
+conditions,
+.\"
+can be made by name as well as by number.
+.P
+Names consist of up to 32 alphanumeric characters and underscores. Named
+capturing parentheses are still allocated numbers as well as names, exactly as
+if the names were not present. The PCRE API provides function calls for
+extracting the name-to-number translation table from a compiled pattern. There
+is also a convenience function for extracting a captured substring by name.
+.P
+By default, a name must be unique within a pattern, but it is possible to relax
+this constraint by setting the PCRE_DUPNAMES option at compile time. (Duplicate
+names are also always permitted for subpatterns with the same number, set up as
+described in the previous section.) Duplicate names can be useful for patterns
+where only one instance of the named parentheses can match. Suppose you want to
+match the name of a weekday, either as a 3-letter abbreviation or as the full
+name, and in both cases you want to extract the abbreviation. This pattern
+(ignoring the line breaks) does the job:
+.sp
+  (?Mon|Fri|Sun)(?:day)?|
+  (?Tue)(?:sday)?|
+  (?Wed)(?:nesday)?|
+  (?Thu)(?:rsday)?|
+  (?Sat)(?:urday)?
+.sp
+There are five capturing substrings, but only one is ever set after a match.
+(An alternative way of solving this problem is to use a "branch reset"
+subpattern, as described in the previous section.)
+.P
+The convenience function for extracting the data by name returns the substring
+for the first (and in this example, the only) subpattern of that name that
+matched. This saves searching to find which numbered subpattern it was.
+.P
+If you make a backreference to a non-unique named subpattern from elsewhere in
+the pattern, the one that corresponds to the first occurrence of the name is
+used. In the absence of duplicate numbers (see the previous section) this is
+the one with the lowest number. If you use a named reference in a condition
+test (see the
+.\"
+.\" HTML 
+.\" 
+section about conditions
+.\"
+below), either to check whether a subpattern has matched, or to check for
+recursion, all subpatterns with the same name are tested. If the condition is
+true for any one of them, the overall condition is true. This is the same
+behaviour as testing by number. For further details of the interfaces for
+handling named subpatterns, see the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation.
+.P
+\fBWarning:\fP You cannot use different names to distinguish between two
+subpatterns with the same number because PCRE uses only the numbers when
+matching. For this reason, an error is given at compile time if different names
+are given to subpatterns with the same number. However, you can give the same
+name to subpatterns with the same number, even when PCRE_DUPNAMES is not set.

+.SH REPETITION
+.rs
+.sp
+Repetition is specified by quantifiers, which can follow any of the following
+items:
+.sp
+  a literal data character
+  the dot metacharacter
+  the \eC escape sequence
+  the \eX escape sequence (in UTF-8 mode with Unicode properties)
+  the \eR escape sequence
+  an escape such as \ed that matches a single character
+  a character class
+  a back reference (see next section)
+  a parenthesized subpattern (unless it is an assertion)
+  a recursive or "subroutine" call to a subpattern
+.sp
+The general repetition quantifier specifies a minimum and maximum number of
+permitted matches, by giving the two numbers in curly brackets (braces),
+separated by a comma. The numbers must be less than 65536, and the first must
+be less than or equal to the second. For example:
+.sp
+  z{2,4}
+.sp
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
+character. If the second number is omitted, but the comma is present, there is
+no upper limit; if the second number and the comma are both omitted, the
+quantifier specifies an exact number of required matches. Thus
+.sp
+  [aeiou]{3,}
+.sp
+matches at least 3 successive vowels, but may match many more, while
+.sp
+  \ed{8}
+.sp
+matches exactly 8 digits. An opening curly bracket that appears in a position
+where a quantifier is not allowed, or one that does not match the syntax of a
+quantifier, is taken as a literal character. For example, {,6} is not a
+quantifier, but a literal string of four characters.
+.P
+In UTF-8 mode, quantifiers apply to UTF-8 characters rather than to individual
+bytes. Thus, for example, \ex{100}{2} matches two UTF-8 characters, each of
+which is represented by a two-byte sequence. Similarly, when Unicode property
+support is available, \eX{3} matches three Unicode extended sequences, each of
+which may be several bytes long (and they may be of different lengths).
+.P
+The quantifier {0} is permitted, causing the expression to behave as if the
+previous item and the quantifier were not present. This may be useful for
+subpatterns that are referenced as
+.\" HTML 
+.\" 
+subroutines
+.\"
+from elsewhere in the pattern. Items other than subpatterns that have a {0}
+quantifier are omitted from the compiled pattern.
+.P
+For convenience, the three most common quantifiers have single-character
+abbreviations:
+.sp
+  *    is equivalent to {0,}
+  +    is equivalent to {1,}
+  ?    is equivalent to {0,1}
+.sp
+It is possible to construct infinite loops by following a subpattern that can
+match no characters with a quantifier that has no upper limit, for example:
+.sp
+  (a?)*
+.sp
+Earlier versions of Perl and PCRE used to give an error at compile time for
+such patterns. However, because there are cases where this can be useful, such
+patterns are now accepted, but if any repetition of the subpattern does in fact
+match no characters, the loop is forcibly broken.
+.P
+By default, the quantifiers are "greedy", that is, they match as much as
+possible (up to the maximum number of permitted times), without causing the
+rest of the pattern to fail. The classic example of where this gives problems
+is in trying to match comments in C programs. These appear between /* and */
+and within the comment, individual * and / characters may appear. An attempt to
+match C comments by applying the pattern
+.sp
+  /\e*.*\e*/
+.sp
+to the string
+.sp
+  /* first comment */  not comment  /* second comment */
+.sp
+fails, because it matches the entire string owing to the greediness of the .*
+item.
+.P
+However, if a quantifier is followed by a question mark, it ceases to be
+greedy, and instead matches the minimum number of times possible, so the
+pattern
+.sp
+  /\e*.*?\e*/
+.sp
+does the right thing with the C comments. The meaning of the various
+quantifiers is not otherwise changed, just the preferred number of matches.
+Do not confuse this use of question mark with its use as a quantifier in its
+own right. Because it has two uses, it can sometimes appear doubled, as in
+.sp
+  \ed??\ed
+.sp
+which matches one digit by preference, but can match two if that is the only
+way the rest of the pattern matches.
+.P
+If the PCRE_UNGREEDY option is set (an option that is not available in Perl),
+the quantifiers are not greedy by default, but individual ones can be made
+greedy by following them with a question mark. In other words, it inverts the
+default behaviour.
+.P
+When a parenthesized subpattern is quantified with a minimum repeat count that
+is greater than 1 or with a limited maximum, more memory is required for the
+compiled pattern, in proportion to the size of the minimum or maximum.
+.P
+If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent
+to Perl's /s) is set, thus allowing the dot to match newlines, the pattern is
+implicitly anchored, because whatever follows will be tried against every
+character position in the subject string, so there is no point in retrying the
+overall match at any position after the first. PCRE normally treats such a
+pattern as though it were preceded by \eA.
+.P
+In cases where it is known that the subject string contains no newlines, it is
+worth setting PCRE_DOTALL in order to obtain this optimization, or
+alternatively using ^ to indicate anchoring explicitly.
+.P
+However, there is one situation where the optimization cannot be used. When .*
+is inside capturing parentheses that are the subject of a backreference
+elsewhere in the pattern, a match at the start may fail where a later one
+succeeds. Consider, for example:
+.sp
+  (.*)abc\e1
+.sp
+If the subject is "xyz123abc123" the match point is the fourth character. For
+this reason, such a pattern is not implicitly anchored.
+.P
+When a capturing subpattern is repeated, the value captured is the substring
+that matched the final iteration. For example, after
+.sp
+  (tweedle[dume]{3}\es*)+
+.sp
+has matched "tweedledum tweedledee" the value of the captured substring is
+"tweedledee". However, if there are nested capturing subpatterns, the
+corresponding captured values may have been set in previous iterations. For
+example, after
+.sp
+  /(a|(b))+/
+.sp
+matches "aba" the value of the second captured substring is "b".
+.
+.
+.\" HTML 
+.SH "ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS"
+.rs
+.sp
+With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy")
+repetition, failure of what follows normally causes the repeated item to be
+re-evaluated to see if a different number of repeats allows the rest of the
+pattern to match. Sometimes it is useful to prevent this, either to change the
+nature of the match, or to cause it fail earlier than it otherwise might, when
+the author of the pattern knows there is no point in carrying on.
+.P
+Consider, for example, the pattern \ed+foo when applied to the subject line
+.sp
+  123456bar
+.sp
+After matching all 6 digits and then failing to match "foo", the normal
+action of the matcher is to try again with only 5 digits matching the \ed+
+item, and then with 4, and so on, before ultimately failing. "Atomic grouping"
+(a term taken from Jeffrey Friedl's book) provides the means for specifying
+that once a subpattern has matched, it is not to be re-evaluated in this way.
+.P
+If we use atomic grouping for the previous example, the matcher gives up
+immediately on failing to match "foo" the first time. The notation is a kind of
+special parenthesis, starting with (?> as in this example:
+.sp
+  (?>\ed+)foo
+.sp
+This kind of parenthesis "locks up" the  part of the pattern it contains once
+it has matched, and a failure further into the pattern is prevented from
+backtracking into it. Backtracking past it to previous items, however, works as
+normal.
+.P
+An alternative description is that a subpattern of this type matches the string
+of characters that an identical standalone pattern would match, if anchored at
+the current point in the subject string.
+.P
+Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as
+the above example can be thought of as a maximizing repeat that must swallow
+everything it can. So, while both \ed+ and \ed+? are prepared to adjust the
+number of digits they match in order to make the rest of the pattern match,
+(?>\ed+) can only match an entire sequence of digits.
+.P
+Atomic groups in general can of course contain arbitrarily complicated
+subpatterns, and can be nested. However, when the subpattern for an atomic
+group is just a single repeated item, as in the example above, a simpler
+notation, called a "possessive quantifier" can be used. This consists of an
+additional + character following a quantifier. Using this notation, the
+previous example can be rewritten as
+.sp
+  \ed++foo
+.sp
+Note that a possessive quantifier can be used with an entire group, for
+example:
+.sp
+  (abc|xyz){2,3}+
+.sp
+Possessive quantifiers are always greedy; the setting of the PCRE_UNGREEDY
+option is ignored. They are a convenient notation for the simpler forms of
+atomic group. However, there is no difference in the meaning of a possessive
+quantifier and the equivalent atomic group, though there may be a performance
+difference; possessive quantifiers should be slightly faster.
+.P
+The possessive quantifier syntax is an extension to the Perl 5.8 syntax.
+Jeffrey Friedl originated the idea (and the name) in the first edition of his
+book. Mike McCloskey liked it, so implemented it when he built Sun's Java
+package, and PCRE copied it from there. It ultimately found its way into Perl
+at release 5.10.
+.P
+PCRE has an optimization that automatically "possessifies" certain simple
+pattern constructs. For example, the sequence A+B is treated as A++B because
+there is no point in backtracking into a sequence of A's when B must follow.
+.P
+When a pattern contains an unlimited repeat inside a subpattern that can itself
+be repeated an unlimited number of times, the use of an atomic group is the
+only way to avoid some failing matches taking a very long time indeed. The
+pattern
+.sp
+  (\eD+|<\ed+>)*[!?]
+.sp
+matches an unlimited number of substrings that either consist of non-digits, or
+digits enclosed in <>, followed by either ! or ?. When it matches, it runs
+quickly. However, if it is applied to
+.sp
+  aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
+.sp
+it takes a long time before reporting failure. This is because the string can
+be divided between the internal \eD+ repeat and the external * repeat in a
+large number of ways, and all have to be tried. (The example uses [!?] rather
+than a single character at the end, because both PCRE and Perl have an
+optimization that allows for fast failure when a single character is used. They
+remember the last single character that is required for a match, and fail early
+if it is not present in the string.) If the pattern is changed so that it uses
+an atomic group, like this:
+.sp
+  ((?>\eD+)|<\ed+>)*[!?]
+.sp
+sequences of non-digits cannot be broken, and failure happens quickly.
+.
+.
+.\" HTML 
+.SH "BACK REFERENCES"
+.rs
+.sp
+Outside a character class, a backslash followed by a digit greater than 0 (and
+possibly further digits) is a back reference to a capturing subpattern earlier
+(that is, to its left) in the pattern, provided there have been that many
+previous capturing left parentheses.
+.P
+However, if the decimal number following the backslash is less than 10, it is
+always taken as a back reference, and causes an error only if there are not
+that many capturing left parentheses in the entire pattern. In other words, the
+parentheses that are referenced need not be to the left of the reference for
+numbers less than 10. A "forward back reference" of this type can make sense
+when a repetition is involved and the subpattern to the right has participated
+in an earlier iteration.
+.P
+It is not possible to have a numerical "forward back reference" to a subpattern
+whose number is 10 or more using this syntax because a sequence such as \e50 is
+interpreted as a character defined in octal. See the subsection entitled
+"Non-printing characters"
+.\" HTML 
+.\" 
+above
+.\"
+for further details of the handling of digits following a backslash. There is
+no such problem when named parentheses are used. A back reference to any
+subpattern is possible using named parentheses (see below).
+.P
+Another way of avoiding the ambiguity inherent in the use of digits following a
+backslash is to use the \eg escape sequence, which is a feature introduced in
+Perl 5.10. This escape must be followed by an unsigned number or a negative
+number, optionally enclosed in braces. These examples are all identical:
+.sp
+  (ring), \e1
+  (ring), \eg1
+  (ring), \eg{1}
+.sp
+An unsigned number specifies an absolute reference without the ambiguity that
+is present in the older syntax. It is also useful when literal digits follow
+the reference. A negative number is a relative reference. Consider this
+example:
+.sp
+  (abc(def)ghi)\eg{-1}
+.sp
+The sequence \eg{-1} is a reference to the most recently started capturing
+subpattern before \eg, that is, is it equivalent to \e2. Similarly, \eg{-2}
+would be equivalent to \e1. The use of relative references can be helpful in
+long patterns, and also in patterns that are created by joining together
+fragments that contain references within themselves.
+.P
+A back reference matches whatever actually matched the capturing subpattern in
+the current subject string, rather than anything matching the subpattern
+itself (see
+.\" HTML 
+.\" 
+"Subpatterns as subroutines"
+.\"
+below for a way of doing that). So the pattern
+.sp
+  (sens|respons)e and \e1ibility
+.sp
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If caseful matching is in force at the time of the
+back reference, the case of letters is relevant. For example,
+.sp
+  ((?i)rah)\es+\e1
+.sp
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
+capturing subpattern is matched caselessly.
+.P
+There are several different ways of writing back references to named
+subpatterns. The .NET syntax \ek{name} and the Perl syntax \ek or
+\ek'name' are supported, as is the Python syntax (?P=name). Perl 5.10's unified
+back reference syntax, in which \eg can be used for both numeric and named
+references, is also supported. We could rewrite the above example in any of
+the following ways:
+.sp
+  (?(?i)rah)\es+\ek
+  (?'p1'(?i)rah)\es+\ek{p1}
+  (?P(?i)rah)\es+(?P=p1)
+  (?(?i)rah)\es+\eg{p1}
+.sp
+A subpattern that is referenced by name may appear in the pattern before or
+after the reference.
+.P
+There may be more than one back reference to the same subpattern. If a
+subpattern has not actually been used in a particular match, any back
+references to it always fail by default. For example, the pattern
+.sp
+  (a|(bc))\e2
+.sp
+always fails if it starts to match "a" rather than "bc". However, if the
+PCRE_JAVASCRIPT_COMPAT option is set at compile time, a back reference to an
+unset value matches an empty string.
+.P
+Because there may be many capturing parentheses in a pattern, all digits
+following a backslash are taken as part of a potential back reference number.
+If the pattern continues with a digit character, some delimiter must be used to
+terminate the back reference. If the PCRE_EXTENDED option is set, this can be
+whitespace. Otherwise, the \eg{ syntax or an empty comment (see
+.\" HTML 
+.\" 
+"Comments"
+.\"
+below) can be used.
+.P
+A back reference that occurs inside the parentheses to which it refers fails
+when the subpattern is first used, so, for example, (a\e1) never matches.
+However, such references can be useful inside repeated subpatterns. For
+example, the pattern
+.sp
+  (a|b\e1)+
+.sp
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
+the subpattern, the back reference matches the character string corresponding
+to the previous iteration. In order for this to work, the pattern must be such
+that the first iteration does not need to match the back reference. This can be
+done using alternation, as in the example above, or by a quantifier with a
+minimum of zero.
+.

+More complicated assertions are coded as subpatterns. There are two kinds:

+that look behind it. An assertion subpattern is matched in the normal way,
+except that it does not cause the current matching position to be changed.
+.P
+Assertion subpatterns are not capturing subpatterns, and may not be repeated,
+because it makes no sense to assert the same thing several times. If any kind
+of assertion contains capturing subpatterns within it, these are counted for
+the purposes of numbering the capturing subpatterns in the whole pattern.
+However, substring capturing is carried out only for positive assertions,
+because it does not make sense for negative assertions.
+.
+.
+.SS "Lookahead assertions"
+.rs
+.sp
+Lookahead assertions start with (?= for positive assertions and (?! for
+negative assertions. For example,

+  \ew+(?=;)
+.sp
+matches a word followed by a semicolon, but does not include the semicolon in
+the match, and
+.sp
+  foo(?!bar)
+.sp
+matches any occurrence of "foo" that is not followed by "bar". Note that the
+apparently similar pattern
+.sp
+  (?!foo)bar
+.sp
+does not find an occurrence of "bar" that is preceded by something other than
+"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
+(?!foo) is always true when the next three characters are "bar". A
+lookbehind assertion is needed to achieve the other effect.
+.P
+If you want to force a matching failure at some point in a pattern, the most
+convenient way to do it is with (?!) because an empty string always matches, so
+an assertion that requires there not to be an empty string must always fail.
+The Perl 5.10 backtracking control verb (*FAIL) or (*F) is essentially a

+what follows matches the rest of the pattern. If the pattern is specified as

+  ^.*abcd$
+.sp
+the initial .* matches the entire string at first, but when this fails (because
+there is no following "a"), it backtracks to match all but the last character,
+then all but the last two characters, and so on. Once again the search for "a"
+covers the entire string, from right to left, so we are no better off. However,
+if the pattern is written as
+.sp
+  ^.*+(?<=abcd)
+.sp
+there can be no backtracking for the .*+ item; it can match only the entire

+The first part matches an optional opening parenthesis, and if that
+character is present, sets it as the first captured substring. The second part
+matches one or more characters that are not parentheses. The third part is a
+conditional subpattern that tests whether the first set of parentheses matched
+or not. If they did, that is, if subject started with an opening parenthesis,
+the condition is true, and so the yes-pattern is executed and a closing
+parenthesis is required. Otherwise, since no-pattern is not present, the

+Perl uses the syntax (?()...) or (?('name')...) to test for a used
+subpattern by name. For compatibility with earlier versions of PCRE, which had
+this facility before Perl, the syntax (?(name)...) is also recognized. However,
+there is a possible ambiguity with this syntax, because subpattern names may
+consist entirely of digits. PCRE looks first for a named subpattern; if it
+cannot find one and the name consists entirely of digits, PCRE looks for a
+subpattern of that number, which must be greater than zero. Using subpattern
+names that consist entirely of digits is not recommended.
+.P
+Rewriting the above example to use a named subpattern gives this:
+.sp
+  (? \e( )?    [^()]+    (?() \e) )
+.sp
+If the name used in a condition of this kind is a duplicate, the test is
+applied to all subpatterns of the same name, and is true if any one of them has
+matched.
+.
+.SS "Checking for pattern recursion"
+.rs
+.sp
+If the condition is the string (R), and there is no subpattern with the name R,
+the condition is true if a recursive call to the whole pattern or any
+subpattern has been made. If digits or a name preceded by ampersand follow the
+letter R, for example:
+.sp
+  (?(R3)...) or (?(R&name)...)
+.sp
+the condition is true if the most recent recursion is into a subpattern whose
+number or name is given. This condition does not check the entire recursion
+stack. If the name used in a condition of this kind is a duplicate, the test is
+applied to all subpatterns of the same name, and is true if any one of them is
+the most recent recursion.
+.P
+At "top level", all these recursion test conditions are false.
+.\" HTML 
+.\" 
+The syntax for recursive patterns
+.\"
+is described below.
+.
+.SS "Defining subpatterns for use by reference only"
+.rs
+.sp
+If the condition is the string (DEFINE), and there is no subpattern with the
+name DEFINE, the condition is always false. In this case, there may be only one
+alternative in the subpattern. It is always skipped if control reaches this
+point in the pattern; the idea of DEFINE is that it can be used to define
+"subroutines" that can be referenced from elsewhere. (The use of
+.\" HTML 
+.\" 
+"subroutines"
+.\"
+is described below.) For example, a pattern to match an IPv4 address could be
+written like this (ignore whitespace and line breaks):
+.sp
+  (?(DEFINE) (? 2[0-4]\ed | 25[0-5] | 1\ed\ed | [1-9]?\ed) )
+  \eb (?&byte) (\e.(?&byte)){3} \eb
+.sp
+The first part of the pattern is a DEFINE group inside which a another group
+named "byte" is defined. This matches an individual component of an IPv4
+address (a number less than 256). When matching takes place, this part of the
+pattern is skipped because DEFINE acts like a false condition. The rest of the
+pattern uses references to the named group to match the four dot-separated
+components of an IPv4 address, insisting on a word boundary at each end.
+.
+.SS "Assertion conditions"
+.rs
+.sp
+If the condition is not in any of the above formats, it must be an assertion.
+This may be a positive or negative lookahead or lookbehind assertion. Consider
+this pattern, again containing non-significant white space, and with the two
+alternatives on the second line:
+.sp
+  (?(?=[^a-z]*[a-z])
+  \ed{2}-[a-z]{3}-\ed{2}  |  \ed{2}-\ed{2}-\ed{2} )
+.sp
+The condition is a positive lookahead assertion that matches an optional
+sequence of non-letters followed by a letter. In other words, it tests for the
+presence of at least one letter in the subject. If a letter is found, the
+subject is matched against the first alternative; otherwise it is matched
+against the second. This pattern matches strings in one of the two forms
+dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+.
+.
+.\" HTML 
+.SH COMMENTS
+.rs
+.sp
+The sequence (?# marks the start of a comment that continues up to the next
+closing parenthesis. Nested parentheses are not permitted. The characters
+that make up a comment play no part in the pattern matching at all.
+.P
+If the PCRE_EXTENDED option is set, an unescaped # character outside a
+character class introduces a comment that continues to immediately after the
+next newline in the pattern.
+.
+.
+.\" HTML 
+.SH "RECURSIVE PATTERNS"
+.rs
+.sp
+Consider the problem of matching a string in parentheses, allowing for
+unlimited nested parentheses. Without the use of recursion, the best that can
+be done is to use a pattern that matches up to some fixed depth of nesting. It
+is not possible to handle an arbitrary nesting depth.
+.P
+For some time, Perl has provided a facility that allows regular expressions to
+recurse (amongst other things). It does this by interpolating Perl code in the
+expression at run time, and the code can refer to the expression itself. A Perl
+pattern using code interpolation to solve the parentheses problem can be
+created like this:
+.sp
+  $re = qr{\e( (?: (?>[^()]+) | (?p{$re}) )* \e)}x;
+.sp
+The (?p{...}) item interpolates Perl code at run time, and in this case refers
+recursively to the pattern in which it appears.
+.P
+Obviously, PCRE cannot support the interpolation of Perl code. Instead, it
+supports special syntax for recursion of the entire pattern, and also for
+individual subpattern recursion. After its introduction in PCRE and Python,
+this kind of recursion was subsequently introduced into Perl at release 5.10.
+.P
+A special item that consists of (? followed by a number greater than zero and a
+closing parenthesis is a recursive call of the subpattern of the given number,
+provided that it occurs inside that subpattern. (If not, it is a
+.\" HTML 
+.\" 
+"subroutine"
+.\"
+call, which is described in the next section.) The special item (?R) or (?0) is
+a recursive call of the entire regular expression.
+.P
+This PCRE pattern solves the nested parentheses problem (assume the
+PCRE_EXTENDED option is set so that white space is ignored):
+.sp
+  \e( ( [^()]++ | (?R) )* \e)
+.sp
+First it matches an opening parenthesis. Then it matches any number of
+substrings which can either be a sequence of non-parentheses, or a recursive
+match of the pattern itself (that is, a correctly parenthesized substring).
+Finally there is a closing parenthesis. Note the use of a possessive quantifier
+to avoid backtracking into sequences of non-parentheses.
+.P
+If this were part of a larger pattern, you would not want to recurse the entire
+pattern, so instead you could use this:
+.sp
+  ( \e( ( [^()]++ | (?1) )* \e) )
+.sp
+We have put the pattern into parentheses, and caused the recursion to refer to
+them instead of the whole pattern.
+.P
+In a larger pattern, keeping track of parenthesis numbers can be tricky. This
+is made easier by the use of relative references (a Perl 5.10 feature).
+Instead of (?1) in the pattern above you can write (?-2) to refer to the second
+most recently opened parentheses preceding the recursion. In other words, a
+negative number counts capturing parentheses leftwards from the point at which
+it is encountered.
+.P
+It is also possible to refer to subsequently opened parentheses, by writing
+references such as (?+2). However, these cannot be recursive because the
+reference is not inside the parentheses that are referenced. They are always
+.\" HTML 
+.\" 
+"subroutine"
+.\"
+calls, as described in the next section.
+.P
+An alternative approach is to use named parentheses instead. The Perl syntax
+for this is (?&name); PCRE's earlier syntax (?P>name) is also supported. We
+could rewrite the above example as follows:
+.sp
+  (? \e( ( [^()]++ | (?&pn) )* \e) )
+.sp
+If there is more than one subpattern with the same name, the earliest one is
+used.
+.P
+This particular example pattern that we have been looking at contains nested
+unlimited repeats, and so the use of a possessive quantifier for matching
+strings of non-parentheses is important when applying the pattern to strings
+that do not match. For example, when this pattern is applied to
+.sp
+  (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
+.sp
+it yields "no match" quickly. However, if a possessive quantifier is not used,
+the match runs for a very long time indeed because there are so many different
+ways the + and * repeats can carve up the subject, and all have to be tested
+before failure can be reported.
+.P
+At the end of a match, the values of capturing parentheses are those from
+the outermost level. If you want to obtain intermediate values, a callout
+function can be used (see below and the
+.\" HREF
+\fBpcrecallout\fP
+.\"
+documentation). If the pattern above is matched against
+.sp
+  (ab(cd)ef)
+.sp
+the value for the inner capturing parentheses (numbered 2) is "ef", which is
+the last value taken on at the top level. If a capturing subpattern is not
+matched at the top level, its final value is unset, even if it is (temporarily)
+set at a deeper level.
+.P
+If there are more than 15 capturing parentheses in a pattern, PCRE has to
+obtain extra memory to store data during a recursion, which it does by using
+\fBpcre_malloc\fP, freeing it via \fBpcre_free\fP afterwards. If no memory can
+be obtained, the match fails with the PCRE_ERROR_NOMEMORY error.
+.P
+Do not confuse the (?R) item with the condition (R), which tests for recursion.
+Consider this pattern, which matches text in angle brackets, allowing for
+arbitrary nesting. Only digits are allowed in nested brackets (that is, when
+recursing), whereas any characters are permitted at the outer level.
+.sp
+  < (?: (?(R) \ed++  | [^<>]*+) | (?R)) * >
+.sp
+In this pattern, (?(R) is the start of a conditional subpattern, with two
+different alternatives for the recursive and non-recursive cases. The (?R) item
+is the actual recursive call.
+.
+.
+.\" HTML 
+.SS "Recursion difference from Perl"
+.rs
+.sp
+In PCRE (like Python, but unlike Perl), a recursive subpattern call is always
+treated as an atomic group. That is, once it has matched some of the subject
+string, it is never re-entered, even if it contains untried alternatives and
+there is a subsequent matching failure. This can be illustrated by the
+following pattern, which purports to match a palindromic string that contains
+an odd number of characters (for example, "a", "aba", "abcba", "abcdcba"):
+.sp
+  ^(.|(.)(?1)\e2)$
+.sp
+The idea is that it either matches a single character, or two identical
+characters surrounding a sub-palindrome. In Perl, this pattern works; in PCRE
+it does not if the pattern is longer than three characters. Consider the
+subject string "abcba":
+.P
+At the top level, the first character is matched, but as it is not at the end
+of the string, the first alternative fails; the second alternative is taken
+and the recursion kicks in. The recursive call to subpattern 1 successfully
+matches the next character ("b"). (Note that the beginning and end of line
+tests are not part of the recursion).
+.P
+Back at the top level, the next character ("c") is compared with what
+subpattern 2 matched, which was "a". This fails. Because the recursion is
+treated as an atomic group, there are now no backtracking points, and so the
+entire match fails. (Perl is able, at this point, to re-enter the recursion and
+try the second alternative.) However, if the pattern is written with the
+alternatives in the other order, things are different:
+.sp
+  ^((.)(?1)\e2|.)$
+.sp
+This time, the recursing alternative is tried first, and continues to recurse
+until it runs out of characters, at which point the recursion fails. But this
+time we do have another alternative to try at the higher level. That is the big
+difference: in the previous case the remaining alternative is at a deeper
+recursion level, which PCRE cannot use.
+.P
+To change the pattern so that matches all palindromic strings, not just those
+with an odd number of characters, it is tempting to change the pattern to this:
+.sp
+  ^((.)(?1)\e2|.?)$
+.sp
+Again, this works in Perl, but not in PCRE, and for the same reason. When a
+deeper recursion has matched a single character, it cannot be entered again in
+order to match an empty string. The solution is to separate the two cases, and
+write out the odd and even cases as alternatives at the higher level:
+.sp
+  ^(?:((.)(?1)\e2|)|((.)(?3)\e4|.))
+.sp
+If you want to match typical palindromic phrases, the pattern has to ignore all
+non-word characters, which can be done like this:
+.sp
+  ^\eW*+(?:((.)\eW*+(?1)\eW*+\e2|)|((.)\eW*+(?3)\eW*+\e4|\eW*+.\eW*+))\eW*+$
+.sp
+If run with the PCRE_CASELESS option, this pattern matches phrases such as "A
+man, a plan, a canal: Panama!" and it works well in both PCRE and Perl. Note
+the use of the possessive quantifier *+ to avoid backtracking into sequences of
+non-word characters. Without this, PCRE takes a great deal longer (ten times or
+more) to match typical phrases, and Perl takes so long that you think it has
+gone into a loop.
+.P
+\fBWARNING\fP: The palindrome-matching patterns above work only if the subject
+string does not start with a palindrome that is shorter than the entire string.
+For example, although "abcba" is correctly matched, if the subject is "ababa",
+PCRE finds the palindrome "aba" at the start, then fails at top level because
+the end of the string does not follow. Once again, it cannot jump back into the
+recursion to try other alternatives, so the entire match fails.
+.
+.
+.\" HTML 
+.SH "SUBPATTERNS AS SUBROUTINES"
+.rs
+.sp
+If the syntax for a recursive subpattern reference (either by number or by
+name) is used outside the parentheses to which it refers, it operates like a
+subroutine in a programming language. The "called" subpattern may be defined
+before or after the reference. A numbered reference can be absolute or
+relative, as in these examples:
+.sp
+  (...(absolute)...)...(?2)...
+  (...(relative)...)...(?-1)...
+  (...(?+1)...(relative)...
+.sp
+An earlier example pointed out that the pattern
+.sp
+  (sens|respons)e and \e1ibility
+.sp
+matches "sense and sensibility" and "response and responsibility", but not
+"sense and responsibility". If instead the pattern
+.sp
+  (sens|respons)e and (?1)ibility
+.sp
+is used, it does match "sense and responsibility" as well as the other two
+strings. Another example is given in the discussion of DEFINE above.
+.P
+Like recursive subpatterns, a subroutine call is always treated as an atomic
+group. That is, once it has matched some of the subject string, it is never
+re-entered, even if it contains untried alternatives and there is a subsequent
+matching failure. Any capturing parentheses that are set during the subroutine
+call revert to their previous values afterwards.
+.P
+When a subpattern is used as a subroutine, processing options such as
+case-independence are fixed when the subpattern is defined. They cannot be
+changed for different calls. For example, consider this pattern:
+.sp
+  (abc)(?i:(?-1))
+.sp
+It matches "abcabc". It does not match "abcABC" because the change of
+processing option does not affect the called subpattern.
+.
+.
+.\" HTML 
+.SH "ONIGURUMA SUBROUTINE SYNTAX"
+.rs
+.sp
+For compatibility with Oniguruma, the non-Perl syntax \eg followed by a name or
+a number enclosed either in angle brackets or single quotes, is an alternative
+syntax for referencing a subpattern as a subroutine, possibly recursively. Here
+are two of the examples used above, rewritten using this syntax:
+.sp
+  (? \e( ( (?>[^()]+) | \eg )* \e) )
+  (sens|respons)e and \eg'1'ibility
+.sp
+PCRE supports an extension to Oniguruma: if a number is preceded by a
+plus or a minus sign it is taken as a relative reference. For example:
+.sp
+  (abc)(?i:\eg<-1>)
+.sp
+Note that \eg{...} (Perl syntax) and \eg<...> (Oniguruma syntax) are \fInot\fP
+synonymous. The former is a back reference; the latter is a subroutine call.
+.
+.
+.SH CALLOUTS
+.rs
+.sp
+Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl
+code to be obeyed in the middle of matching a regular expression. This makes it
+possible, amongst other things, to extract different substrings that match the
+same pair of parentheses when there is a repetition.
+.P
+PCRE provides a similar feature, but of course it cannot obey arbitrary Perl
+code. The feature is called "callout". The caller of PCRE provides an external
+function by putting its entry point in the global variable \fIpcre_callout\fP.
+By default, this variable contains NULL, which disables all calling out.
+.P
+Within a regular expression, (?C) indicates the points at which the external
+function is to be called. If you want to identify different callout points, you
+can put a number less than 256 after the letter C. The default value is zero.
+For example, this pattern has two callout points:
+.sp
+  (?C1)abc(?C2)def
+.sp
+If the PCRE_AUTO_CALLOUT flag is passed to \fBpcre_compile()\fP, callouts are
+automatically installed before each item in the pattern. They are all numbered
+255.
+.P
+During matching, when PCRE reaches a callout point (and \fIpcre_callout\fP is
+set), the external function is called. It is provided with the number of the
+callout, the position in the pattern, and, optionally, one item of data
+originally supplied by the caller of \fBpcre_exec()\fP. The callout function
+may cause matching to proceed, to backtrack, or to fail altogether. A complete
+description of the interface to the callout function is given in the
+.\" HREF
+\fBpcrecallout\fP
+.\"
+documentation.
+.
+.
+.SH "BACKTRACKING CONTROL"
+.rs
+.sp
+Perl 5.10 introduced a number of "Special Backtracking Control Verbs", which
+are described in the Perl documentation as "experimental and subject to change
+or removal in a future version of Perl". It goes on to say: "Their usage in
+production code should be noted to avoid problems during upgrades." The same
+remarks apply to the PCRE features described in this section.
+.P
+Since these verbs are specifically related to backtracking, most of them can be
+used only when the pattern is to be matched using \fBpcre_exec()\fP, which uses
+a backtracking algorithm. With the exception of (*FAIL), which behaves like a
+failing negative assertion, they cause an error if encountered by
+\fBpcre_dfa_exec()\fP.
+.P
+If any of these verbs are used in an assertion or subroutine subpattern
+(including recursive subpatterns), their effect is confined to that subpattern;
+it does not extend to the surrounding pattern. Note that such subpatterns are
+processed as anchored at the point where they are tested.
+.P
+The new verbs make use of what was previously invalid syntax: an opening
+parenthesis followed by an asterisk. In Perl, they are generally of the form
+(*VERB:ARG) but PCRE does not support the use of arguments, so its general
+form is just (*VERB). Any number of these verbs may occur in a pattern. There
+are two kinds:
+.
+.SS "Verbs that act immediately"
+.rs
+.sp
+The following verbs act as soon as they are encountered:
+.sp
+   (*ACCEPT)
+.sp
+This verb causes the match to end successfully, skipping the remainder of the
+pattern. When inside a recursion, only the innermost pattern is ended
+immediately. If (*ACCEPT) is inside capturing parentheses, the data so far is
+captured. (This feature was added to PCRE at release 8.00.) For example:
+.sp
+  A((?:A|B(*ACCEPT)|C)D)
+.sp
+This matches "AB", "AAD", or "ACD"; when it matches "AB", "B" is captured by
+the outer parentheses.
+.sp
+  (*FAIL) or (*F)
+.sp
+This verb causes the match to fail, forcing backtracking to occur. It is
+equivalent to (?!) but easier to read. The Perl documentation notes that it is
+probably useful only when combined with (?{}) or (??{}). Those are, of course,
+Perl features that are not present in PCRE. The nearest equivalent is the
+callout feature, as for example in this pattern:
+.sp
+  a+(?C)(*FAIL)
+.sp
+A match with the string "aaaa" always fails, but the callout is taken before
+each backtrack happens (in this example, 10 times).
+.
+.SS "Verbs that act after backtracking"
+.rs
+.sp
+The following verbs do nothing when they are encountered. Matching continues
+with what follows, but if there is no subsequent match, a failure is forced.
+The verbs differ in exactly what kind of failure occurs.
+.sp
+  (*COMMIT)
+.sp
+This verb causes the whole match to fail outright if the rest of the pattern
+does not match. Even if the pattern is unanchored, no further attempts to find
+a match by advancing the starting point take place. Once (*COMMIT) has been
+passed, \fBpcre_exec()\fP is committed to finding a match at the current
+starting point, or not at all. For example:
+.sp
+  a+(*COMMIT)b
+.sp
+This matches "xxaab" but not "aacaab". It can be thought of as a kind of
+dynamic anchor, or "I've started, so I must finish."
+.sp
+  (*PRUNE)
+.sp
+This verb causes the match to fail at the current position if the rest of the
+pattern does not match. If the pattern is unanchored, the normal "bumpalong"
+advance to the next starting character then happens. Backtracking can occur as
+usual to the left of (*PRUNE), or when matching to the right of (*PRUNE), but
+if there is no match to the right, backtracking cannot cross (*PRUNE).
+In simple cases, the use of (*PRUNE) is just an alternative to an atomic
+group or possessive quantifier, but there are some uses of (*PRUNE) that cannot
+be expressed in any other way.
+.sp
+  (*SKIP)
+.sp
+This verb is like (*PRUNE), except that if the pattern is unanchored, the
+"bumpalong" advance is not to the next character, but to the position in the
+subject where (*SKIP) was encountered. (*SKIP) signifies that whatever text
+was matched leading up to it cannot be part of a successful match. Consider:
+.sp
+  a+(*SKIP)b
+.sp
+If the subject is "aaaac...", after the first match attempt fails (starting at
+the first character in the string), the starting point skips on to start the
+next attempt at "c". Note that a possessive quantifer does not have the same
+effect as this example; although it would suppress backtracking during the
+first match attempt, the second attempt would start at the second character
+instead of skipping on to "c".
+.sp
+  (*THEN)
+.sp
+This verb causes a skip to the next alternation if the rest of the pattern does
+not match. That is, it cancels pending backtracking, but only within the
+current alternation. Its name comes from the observation that it can be used
+for a pattern-based if-then-else block:
+.sp
+  ( COND1 (*THEN) FOO | COND2 (*THEN) BAR | COND3 (*THEN) BAZ ) ...
+.sp
+If the COND1 pattern matches, FOO is tried (and possibly further items after
+the end of the group if FOO succeeds); on failure the matcher skips to the
+second alternative and tries COND2, without backtracking into COND1. If (*THEN)
+is used outside of any alternation, it acts exactly like (*PRUNE).

+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH "PCRE PERFORMANCE"
+.rs
+.sp
+Two aspects of performance are discussed below: memory usage and processing
+time. The way you express your pattern as a regular expression can affect both
+of them.
+.
+.SH "MEMORY USAGE"
+.rs
+.sp
+Patterns are compiled by PCRE into a reasonably efficient byte code, so that
+most simple patterns do not use much memory. However, there is one case where
+memory usage can be unexpectedly large. When a parenthesized subpattern has a
+quantifier with a minimum greater than 1 and/or a limited maximum, the whole
+subpattern is repeated in the compiled code. For example, the pattern
+.sp
+  (abc|def){2,4}
+.sp
+is compiled as if it were
+.sp
+  (abc|def)(abc|def)((abc|def)(abc|def)?)?
+.sp
+(Technical aside: It is done this way so that backtrack points within each of
+the repetitions can be independently maintained.)
+.P
+For regular expressions whose quantifiers use only small numbers, this is not
+usually a problem. However, if the numbers are large, and particularly if such
+repetitions are nested, the memory usage can become an embarrassment. For
+example, the very simple pattern
+.sp
+  ((ab){1,1000}c){1,3}
+.sp
+uses 51K bytes when compiled. When PCRE is compiled with its default internal
+pointer size of two bytes, the size limit on a compiled pattern is 64K, and
+this is reached with the above pattern if the outer repetition is increased
+from 3 to 4. PCRE can be compiled to use larger internal pointers and thus
+handle larger compiled patterns, but it is better to try to rewrite your
+pattern to use less memory if you can.
+.P
+One way of reducing the memory usage for such patterns is to make use of PCRE's
+.\" HTML 
+.\" 
+"subroutine"
+.\"
+facility. Re-writing the above pattern as
+.sp
+  ((ab)(?2){0,999}c)(?1){0,2}
+.sp
+reduces the memory requirements to 18K, and indeed it remains under 20K even
+with the outer repetition increased to 100. However, this pattern is not
+exactly equivalent, because the "subroutine" calls are treated as
+.\" HTML 
+.\" 
+atomic groups
+.\"
+into which there can be no backtracking if there is a subsequent matching
+failure. Therefore, PCRE cannot do this kind of rewriting automatically.
+Furthermore, there is a noticeable loss of speed when executing the modified
+pattern. Nevertheless, if the atomic grouping is not a problem and the loss of
+speed is acceptable, this kind of rewriting will allow you to process patterns
+that PCRE cannot otherwise handle.
+.
+.SH "PROCESSING TIME"
+.rs
+.sp
+Certain items in regular expression patterns are processed more efficiently
+than others. It is more efficient to use a character class like [aeiou] than a
+set of single-character alternatives such as (a|e|i|o|u). In general, the
+simplest construction that provides the required behaviour is usually the most
+efficient. Jeffrey Friedl's book contains a lot of useful general discussion
+about optimizing regular expressions for efficient performance. This document
+contains a few observations about PCRE.
+.P
+Using Unicode character properties (the \ep, \eP, and \eX escapes) is slow,
+because PCRE has to scan a structure that contains data for over fifteen
+thousand characters whenever it needs a character's property. If you can find
+an alternative pattern that does not use character properties, it will probably
+be faster.
+.P
+When a pattern begins with .* not in parentheses, or in parentheses that are
+not the subject of a backreference, and the PCRE_DOTALL option is set, the
+pattern is implicitly anchored by PCRE, since it can match only at the start of
+a subject string. However, if PCRE_DOTALL is not set, PCRE cannot make this
+optimization, because the . metacharacter does not then match a newline, and if
+the subject string contains newlines, the pattern may match from the character
+immediately following one of them instead of from the very start. For example,
+the pattern
+.sp
+  .*second
+.sp
+matches the subject "first\enand second" (where \en stands for a newline
+character), with the match starting at the seventh character. In order to do
+this, PCRE has to retry the match starting after every newline in the subject.
+.P
+If you are using such a pattern with subject strings that do not contain
+newlines, the best performance is obtained by setting PCRE_DOTALL, or starting
+the pattern with ^.* or ^.*? to indicate explicit anchoring. That saves PCRE
+from having to scan along the subject looking for a newline to restart at.
+.P
+Beware of patterns that contain nested indefinite repeats. These can take a
+long time to run when applied to a string that does not match. Consider the
+pattern fragment
+.sp
+  ^(a+)*
+.sp
+This can match "aaaa" in 16 different ways, and this number increases very
+rapidly as the string gets longer. (The * repeat can match 0, 1, 2, 3, or 4
+times, and for each of those cases other than 0 or 4, the + repeats can match
+different numbers of times.) When the remainder of the pattern is such that the
+entire match is going to fail, PCRE has in principle to try every possible
+variation, and this can take an extremely long time, even for relatively short
+strings.
+.P
+An optimization catches some of the more simple cases such as
+.sp
+  (a+)*b
+.sp
+where a literal character follows. Before embarking on the standard matching
+procedure, PCRE checks that there is a "b" later in the subject string, and if
+there is not, it fails the match immediately. However, when there is no
+following literal this optimization cannot be used. You can see the difference
+by comparing the behaviour of
+.sp
+  (a+)*\ed
+.sp
+with the pattern above. The former gives a failure almost instantly when
+applied to a whole line of "a" characters, whereas the latter takes an
+appreciable time with strings longer than about 20 characters.
+.P
+In many cases, the solution to this kind of performance issue is to use an
+atomic group or a possessive quantifier.

+.SH DESCRIPTION
+.rs
+.sp
+This set of functions provides a POSIX-style API to the PCRE regular expression
+package. See the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation for a description of PCRE's native API, which contains much
+additional functionality.
+.P
+The functions described here are just wrapper functions that ultimately call
+the PCRE native API. Their prototypes are defined in the \fBpcreposix.h\fP
+header file, and on Unix systems the library itself is called
+\fBpcreposix.a\fP, so can be accessed by adding \fB-lpcreposix\fP to the
+command for linking an application that uses them. Because the POSIX functions
+call the native ones, it is also necessary to add \fB-lpcre\fP.
+.P
+I have implemented only those POSIX option bits that can be reasonably mapped
+to PCRE native options. In addition, the option REG_EXTENDED is defined with
+the value zero. This has no effect, but since programs that are written to the
+POSIX interface often use it, this makes it easier to slot in PCRE as a
+replacement library. Other POSIX options are not even defined.
+.P
+There are also some other options that are not defined by POSIX. These have
+been added at the request of users who want to make use of certain
+PCRE-specific features via the POSIX calling interface.
+.P
+When PCRE is called via these functions, it is only the API that is POSIX-like
+in style. The syntax and semantics of the regular expressions themselves are
+still those of Perl, subject to the setting of various PCRE options, as
+described below. "POSIX-like in style" means that the API approximates to the
+POSIX definition; it is not fully POSIX-compatible, and in multi-byte encoding
+domains it is probably even less compatible.
+.P
+The header for these functions is supplied as \fBpcreposix.h\fP to avoid any
+potential clash with other POSIX libraries. It can, of course, be renamed or
+aliased as \fBregex.h\fP, which is the "correct" name. It provides two
+structure types, \fIregex_t\fP for compiled internal forms, and
+\fIregmatch_t\fP for returning captured substrings. It also defines some
+constants whose names start with "REG_"; these are used for setting options and
+identifying error codes.
+.P
+.SH "COMPILING A PATTERN"
+.rs
+.sp
+The function \fBregcomp()\fP is called to compile a pattern into an
+internal form. The pattern is a C string terminated by a binary zero, and
+is passed in the argument \fIpattern\fP. The \fIpreg\fP argument is a pointer
+to a \fBregex_t\fP structure that is used as a base for storing information
+about the compiled regular expression.
+.P
+The argument \fIcflags\fP is either zero, or contains one or more of the bits
+defined by the following macros:
+.sp
+  REG_DOTALL
+.sp
+The PCRE_DOTALL option is set when the regular expression is passed for
+compilation to the native function. Note that REG_DOTALL is not part of the
+POSIX standard.
+.sp
+  REG_ICASE
+.sp
+The PCRE_CASELESS option is set when the regular expression is passed for
+compilation to the native function.
+.sp
+  REG_NEWLINE
+.sp
+The PCRE_MULTILINE option is set when the regular expression is passed for
+compilation to the native function. Note that this does \fInot\fP mimic the
+defined POSIX behaviour for REG_NEWLINE (see the following section).
+.sp
+  REG_NOSUB
+.sp
+The PCRE_NO_AUTO_CAPTURE option is set when the regular expression is passed
+for compilation to the native function. In addition, when a pattern that is
+compiled with this flag is passed to \fBregexec()\fP for matching, the
+\fInmatch\fP and \fIpmatch\fP arguments are ignored, and no captured strings
+are returned.
+.sp
+  REG_UNGREEDY
+.sp
+The PCRE_UNGREEDY option is set when the regular expression is passed for
+compilation to the native function. Note that REG_UNGREEDY is not part of the
+POSIX standard.
+.sp
+  REG_UTF8
+.sp
+The PCRE_UTF8 option is set when the regular expression is passed for
+compilation to the native function. This causes the pattern itself and all data
+strings used for matching it to be treated as UTF-8 strings. Note that REG_UTF8
+is not part of the POSIX standard.
+.P
+In the absence of these flags, no options are passed to the native function.
+This means the the regex is compiled with PCRE default semantics. In
+particular, the way it handles newline characters in the subject string is the
+Perl way, not the POSIX way. Note that setting PCRE_MULTILINE has only
+\fIsome\fP of the effects specified for REG_NEWLINE. It does not affect the way
+newlines are matched by . (they are not) or by a negative class such as [^a]
+(they are).
+.P
+The yield of \fBregcomp()\fP is zero on success, and non-zero otherwise. The
+\fIpreg\fP structure is filled in on success, and one member of the structure
+is public: \fIre_nsub\fP contains the number of capturing subpatterns in
+the regular expression. Various error codes are defined in the header file.
+.P
+NOTE: If the yield of \fBregcomp()\fP is non-zero, you must not attempt to
+use the contents of the \fIpreg\fP structure. If, for example, you pass it to
+\fBregexec()\fP, the result is undefined and your program is likely to crash.
+.
+.
+.SH "MATCHING NEWLINE CHARACTERS"
+.rs
+.sp
+This area is not simple, because POSIX and Perl take different views of things.
+It is not possible to get PCRE to obey POSIX semantics, but then PCRE was never
+intended to be a POSIX engine. The following table lists the different
+possibilities for matching newline characters in PCRE:
+.sp
+                          Default   Change with
+.sp
+  . matches newline          no     PCRE_DOTALL
+  newline matches [^a]       yes    not changeable
+  $ matches \en at end        yes    PCRE_DOLLARENDONLY
+  $ matches \en in middle     no     PCRE_MULTILINE
+  ^ matches \en in middle     no     PCRE_MULTILINE
+.sp
+This is the equivalent table for POSIX:
+.sp
+                          Default   Change with
+.sp
+  . matches newline          yes    REG_NEWLINE
+  newline matches [^a]       yes    REG_NEWLINE
+  $ matches \en at end        no     REG_NEWLINE
+  $ matches \en in middle     no     REG_NEWLINE
+  ^ matches \en in middle     no     REG_NEWLINE
+.sp
+PCRE's behaviour is the same as Perl's, except that there is no equivalent for
+PCRE_DOLLAR_ENDONLY in Perl. In both PCRE and Perl, there is no way to stop
+newline from matching [^a].
+.P
+The default POSIX newline handling can be obtained by setting PCRE_DOTALL and
+PCRE_DOLLAR_ENDONLY, but there is no way to make PCRE behave exactly as for the
+REG_NEWLINE action.
+.
+.
+.SH "MATCHING A PATTERN"
+.rs
+.sp
+The function \fBregexec()\fP is called to match a compiled pattern \fIpreg\fP
+against a given \fIstring\fP, which is by default terminated by a zero byte
+(but see REG_STARTEND below), subject to the options in \fIeflags\fP. These can
+be:
+.sp
+  REG_NOTBOL
+.sp
+The PCRE_NOTBOL option is set when calling the underlying PCRE matching
+function.
+.sp
+  REG_NOTEMPTY
+.sp
+The PCRE_NOTEMPTY option is set when calling the underlying PCRE matching
+function. Note that REG_NOTEMPTY is not part of the POSIX standard. However,
+setting this option can give more POSIX-like behaviour in some situations.
+.sp
+  REG_NOTEOL
+.sp
+The PCRE_NOTEOL option is set when calling the underlying PCRE matching
+function.
+.sp
+  REG_STARTEND
+.sp
+The string is considered to start at \fIstring\fP + \fIpmatch[0].rm_so\fP and
+to have a terminating NUL located at \fIstring\fP + \fIpmatch[0].rm_eo\fP
+(there need not actually be a NUL at that location), regardless of the value of
+\fInmatch\fP. This is a BSD extension, compatible with but not specified by
+IEEE Standard 1003.2 (POSIX.2), and should be used with caution in software
+intended to be portable to other systems. Note that a non-zero \fIrm_so\fP does
+not imply REG_NOTBOL; REG_STARTEND affects only the location of the string, not
+how it is matched.
+.P
+If the pattern was compiled with the REG_NOSUB flag, no data about any matched
+strings is returned. The \fInmatch\fP and \fIpmatch\fP arguments of
+\fBregexec()\fP are ignored.
+.P
+If the value of \fInmatch\fP is zero, or if the value \fIpmatch\fP is NULL,
+no data about any matched strings is returned.
+.P
+Otherwise,the portion of the string that was matched, and also any captured
+substrings, are returned via the \fIpmatch\fP argument, which points to an
+array of \fInmatch\fP structures of type \fIregmatch_t\fP, containing the
+members \fIrm_so\fP and \fIrm_eo\fP. These contain the offset to the first
+character of each substring and the offset to the first character after the end
+of each substring, respectively. The 0th element of the vector relates to the
+entire portion of \fIstring\fP that was matched; subsequent elements relate to
+the capturing subpatterns of the regular expression. Unused entries in the
+array have both structure members set to -1.
+.P
+A successful match yields a zero return; various error codes are defined in the
+header file, of which REG_NOMATCH is the "expected" failure code.
+.
+.
+.SH "ERROR MESSAGES"
+.rs
+.sp
+The \fBregerror()\fP function maps a non-zero errorcode from either
+\fBregcomp()\fP or \fBregexec()\fP to a printable message. If \fIpreg\fP is not
+NULL, the error should have arisen from the use of that structure. A message
+terminated by a binary zero is placed in \fIerrbuf\fP. The length of the
+message, including the zero, is limited to \fIerrbuf_size\fP. The yield of the
+function is the size of buffer needed to hold the whole message.
+.
+.
+.SH MEMORY USAGE
+.rs
+.sp
+Compiling a regular expression causes memory to be allocated and associated
+with the \fIpreg\fP structure. The function \fBregfree()\fP frees all such
+memory, after which \fIpreg\fP may no longer be used as a compiled expression.

+.TH PCREPRECOMPILE 3
+.SH NAME
+PCRE - Perl-compatible regular expressions
+.SH "SAVING AND RE-USING PRECOMPILED PCRE PATTERNS"
+.rs
+.sp
+If you are running an application that uses a large number of regular
+expression patterns, it may be useful to store them in a precompiled form
+instead of having to compile them every time the application is run.
+If you are not using any private character tables (see the
+.\" HREF
+\fBpcre_maketables()\fP
+.\"
+documentation), this is relatively straightforward. If you are using private
+tables, it is a little bit more complicated.
+.P
+If you save compiled patterns to a file, you can copy them to a different host
+and run them there. This works even if the new host has the opposite endianness
+to the one on which the patterns were compiled. There may be a small
+performance penalty, but it should be insignificant. However, compiling regular
+expressions with one version of PCRE for use with a different version is not
+guaranteed to work and may cause crashes.
+.
+.
+.SH "SAVING A COMPILED PATTERN"
+.rs
+.sh
+The value returned by \fBpcre_compile()\fP points to a single block of memory
+that holds the compiled pattern and associated data. You can find the length of
+this block in bytes by calling \fBpcre_fullinfo()\fP with an argument of
+PCRE_INFO_SIZE. You can then save the data in any appropriate manner. Here is
+sample code that compiles a pattern and writes it to a file. It assumes that
+the variable \fIfd\fP refers to a file that is open for output:
+.sp
+  int erroroffset, rc, size;
+  char *error;
+  pcre *re;
+.sp
+  re = pcre_compile("my pattern", 0, &error, &erroroffset, NULL);
+  if (re == NULL) { ... handle errors ... }
+  rc = pcre_fullinfo(re, NULL, PCRE_INFO_SIZE, &size);
+  if (rc < 0) { ... handle errors ... }
+  rc = fwrite(re, 1, size, fd);
+  if (rc != size) { ... handle errors ... }
+.sp
+In this example, the bytes that comprise the compiled pattern are copied
+exactly. Note that this is binary data that may contain any of the 256 possible
+byte values. On systems that make a distinction between binary and non-binary
+data, be sure that the file is opened for binary output.
+.P
+If you want to write more than one pattern to a file, you will have to devise a
+way of separating them. For binary data, preceding each pattern with its length
+is probably the most straightforward approach. Another possibility is to write
+out the data in hexadecimal instead of binary, one pattern to a line.
+.P
+Saving compiled patterns in a file is only one possible way of storing them for
+later use. They could equally well be saved in a database, or in the memory of
+some daemon process that passes them via sockets to the processes that want
+them.
+.P
+If the pattern has been studied, it is also possible to save the study data in
+a similar way to the compiled pattern itself. When studying generates
+additional information, \fBpcre_study()\fP returns a pointer to a
+\fBpcre_extra\fP data block. Its format is defined in the
+.\" HTML 
+.\" 
+section on matching a pattern
+.\"
+in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation. The \fIstudy_data\fP field points to the binary study data, and
+this is what you must save (not the \fBpcre_extra\fP block itself). The length
+of the study data can be obtained by calling \fBpcre_fullinfo()\fP with an
+argument of PCRE_INFO_STUDYSIZE. Remember to check that \fBpcre_study()\fP did
+return a non-NULL value before trying to save the study data.
+.
+.
+.SH "RE-USING A PRECOMPILED PATTERN"
+.rs
+.sp
+Re-using a precompiled pattern is straightforward. Having reloaded it into main
+memory, you pass its pointer to \fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP in
+the usual way. This should work even on another host, and even if that host has
+the opposite endianness to the one where the pattern was compiled.
+.P
+However, if you passed a pointer to custom character tables when the pattern
+was compiled (the \fItableptr\fP argument of \fBpcre_compile()\fP), you must
+now pass a similar pointer to \fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP,
+because the value saved with the compiled pattern will obviously be nonsense. A
+field in a \fBpcre_extra()\fP block is used to pass this data, as described in
+the
+.\" HTML 
+.\" 
+section on matching a pattern
+.\"
+in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation.
+.P
+If you did not provide custom character tables when the pattern was compiled,
+the pointer in the compiled pattern is NULL, which causes \fBpcre_exec()\fP to
+use PCRE's internal tables. Thus, you do not need to take any special action at
+run time in this case.
+.P
+If you saved study data with the compiled pattern, you need to create your own
+\fBpcre_extra\fP data block and set the \fIstudy_data\fP field to point to the
+reloaded study data. You must also set the PCRE_EXTRA_STUDY_DATA bit in the
+\fIflags\fP field to indicate that study data is present. Then pass the
+\fBpcre_extra\fP block to \fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP in the
+usual way.
+.
+.
+.SH "COMPATIBILITY WITH DIFFERENT PCRE RELEASES"
+.rs
+.sp
+In general, it is safest to recompile all saved patterns when you update to a
+new PCRE release, though not all updates actually require this. Recompiling is
+definitely needed for release 7.2.

+.sp
+A simple, complete demonstration program, to get you started with using PCRE,
+is supplied in the file \fIpcredemo.c\fP in the PCRE distribution. A listing of
+this program is given in the
+.\" HREF
+\fBpcredemo\fP
+.\"
+documentation. If you do not have a copy of the PCRE distribution, you can save
+this listing to re-create \fIpcredemo.c\fP.
+.P
+The program compiles the regular expression that is its first argument, and
+matches it against the subject string in its second argument. No PCRE options
+are set, and default character tables are used. If matching succeeds, the
+program outputs the portion of the subject that matched, together with the
+contents of any captured substrings.
+.P
+If the -g option is given on the command line, the program then goes on to
+check for further matches of the same regular expression in the same subject
+string. The logic is a little bit tricky because of the possibility of matching
+an empty string. Comments in the code explain what is going on.
+.P
+If PCRE is installed in the standard include and library directories for your
+operating system, you should be able to compile the demonstration program using
+this command:
+.sp
+  gcc -o pcredemo pcredemo.c -lpcre
+.sp
+If PCRE is installed elsewhere, you may need to add additional options to the
+command line. For example, on a Unix-like system that has PCRE installed in
+\fI/usr/local\fP, you can compile the demonstration program using a command
+like this:
+.sp
+.\" JOINSH
+  gcc -o pcredemo -I/usr/local/include pcredemo.c \e
+      -L/usr/local/lib -lpcre
+.sp
+Once you have compiled the demonstration program, you can run simple tests like
+this:
+.sp
+  ./pcredemo 'cat|dog' 'the cat sat on the mat'
+  ./pcredemo -g 'cat|dog' 'the dog sat on the cat'
+.sp
+Note that there is a much more comprehensive test program, called
+.\" HREF
+\fBpcretest\fP,
+.\"
+which supports many more facilities for testing regular expressions and the
+PCRE library. The
+.\" HREF
+\fBpcredemo\fP
+.\"
+program is provided as a simple coding example.
+.P
+When you try to run
+.\" HREF
+\fBpcredemo\fP
+.\"
+when PCRE is not installed in the standard library directory, you may get an
+error like this on some operating systems (e.g. Solaris):
+.sp
+  ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory
+.sp
+This is caused by the way shared library support works on those systems. You
+need to add
+.sp
+  -R/usr/local/lib
+.sp
+(for example) to the compile command to get round this problem.

+PCRE - Perl-compatible regular expressions
+.SH "PCRE DISCUSSION OF STACK USAGE"
+.rs
+.sp
+When you call \fBpcre_exec()\fP, it makes use of an internal function called
+\fBmatch()\fP. This calls itself recursively at branch points in the pattern,
+in order to remember the state of the match so that it can back up and try a
+different alternative if the first one fails. As matching proceeds deeper and
+deeper into the tree of possibilities, the recursion depth increases.
+.P
+Not all calls of \fBmatch()\fP increase the recursion depth; for an item such
+as a* it may be called several times at the same level, after matching
+different numbers of a's. Furthermore, in a number of cases where the result of
+the recursive call would immediately be passed back as the result of the
+current call (a "tail recursion"), the function is just restarted instead.
+.P
+The \fBpcre_dfa_exec()\fP function operates in an entirely different way, and
+hardly uses recursion at all. The limit on its complexity is the amount of
+workspace it is given. The comments that follow do NOT apply to
+\fBpcre_dfa_exec()\fP; they are relevant only for \fBpcre_exec()\fP.
+.P
+You can set limits on the number of times that \fBmatch()\fP is called, both in
+total and recursively. If the limit is exceeded, an error occurs. For details,
+see the
+.\" HTML 
+.\" 
+section on extra data for \fBpcre_exec()\fP
+.\"
+in the
+.\" HREF

+.\"
+documentation.
+.P
+Each time that \fBmatch()\fP is actually called recursively, it uses memory
+from the process stack. For certain kinds of pattern and data, very large
+amounts of stack may be needed, despite the recognition of "tail recursion".
+You can often reduce the amount of recursion, and therefore the amount of stack
+used, by modifying the pattern that is being matched. Consider, for example,
+this pattern:
+.sp
+  ([^<]|<(?!inet))+

+.SH NAME
+pcretest - a program for testing Perl-compatible regular expressions.
+.SH SYNOPSIS
+.rs
+.sp
+.B pcretest "[options] [source] [destination]"
+.sp
+\fBpcretest\fP was written as a test program for the PCRE regular expression
+library itself, but it can also be used for experimenting with regular
+expressions. This document describes the features of the test program; for
+details of the regular expressions themselves, see the
+.\" HREF
+\fBpcrepattern\fP
+.\"
+documentation. For details of the PCRE library function calls and their
+options, see the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation.
+.
+.
+.SH OPTIONS
+.rs
+.TP 10
+\fB-b\fP
+Behave as if each regex has the \fB/B\fP (show bytecode) modifier; the internal
+form is output after compilation.
+.TP 10
+\fB-C\fP
+Output the version number of the PCRE library, and all available information
+about the optional features that are included, and then exit.
+.TP 10
+\fB-d\fP
+Behave as if each regex has the \fB/D\fP (debug) modifier; the internal
+form and information about the compiled pattern is output after compilation;
+\fB-d\fP is equivalent to \fB-b -i\fP.
+.TP 10
+\fB-dfa\fP
+Behave as if each data line contains the \eD escape sequence; this causes the
+alternative matching function, \fBpcre_dfa_exec()\fP, to be used instead of the
+standard \fBpcre_exec()\fP function (more detail is given below).
+.TP 10
+\fB-help\fP
+Output a brief summary these options and then exit.
+.TP 10
+\fB-i\fP
+Behave as if each regex has the \fB/I\fP modifier; information about the
+compiled pattern is given after compilation.
+.TP 10
+\fB-M\fP
+Behave as if each data line contains the \eM escape sequence; this causes
+PCRE to discover the minimum MATCH_LIMIT and MATCH_LIMIT_RECURSION settings by
+calling \fBpcre_exec()\fP repeatedly with different limits.
+.TP 10
+\fB-m\fP
+Output the size of each compiled pattern after it has been compiled. This is
+equivalent to adding \fB/M\fP to each regular expression. For compatibility
+with earlier versions of pcretest, \fB-s\fP is a synonym for \fB-m\fP.
+.TP 10
+\fB-o\fP \fIosize\fP
+Set the number of elements in the output vector that is used when calling
+\fBpcre_exec()\fP or \fBpcre_dfa_exec()\fP to be \fIosize\fP. The default value
+is 45, which is enough for 14 capturing subexpressions for \fBpcre_exec()\fP or
+22 different matches for \fBpcre_dfa_exec()\fP. The vector size can be
+changed for individual matching calls by including \eO in the data line (see
+below).
+.TP 10
+\fB-p\fP
+Behave as if each regex has the \fB/P\fP modifier; the POSIX wrapper API is
+used to call PCRE. None of the other options has any effect when \fB-p\fP is
+set.
+.TP 10
+\fB-q\fP
+Do not output the version number of \fBpcretest\fP at the start of execution.
+.TP 10
+\fB-S\fP \fIsize\fP
+On Unix-like systems, set the size of the runtime stack to \fIsize\fP
+megabytes.
+.TP 10
+\fB-t\fP
+Run each compile, study, and match many times with a timer, and output
+resulting time per compile or match (in milliseconds). Do not set \fB-m\fP with
+\fB-t\fP, because you will then get the size output a zillion times, and the
+timing will be distorted. You can control the number of iterations that are
+used for timing by following \fB-t\fP with a number (as a separate item on the
+command line). For example, "-t 1000" would iterate 1000 times. The default is
+to iterate 500000 times.
+.TP 10
+\fB-tm\fP
+This is like \fB-t\fP except that it times only the matching phase, not the
+compile or study phases.
+.
+.
+.SH DESCRIPTION
+.rs
+.sp
+If \fBpcretest\fP is given two filename arguments, it reads from the first and
+writes to the second. If it is given only one filename argument, it reads from
+that file and writes to stdout. Otherwise, it reads from stdin and writes to
+stdout, and prompts for each line of input, using "re>" to prompt for regular
+expressions, and "data>" to prompt for data lines.
+.P
+When \fBpcretest\fP is built, a configuration option can specify that it should
+be linked with the \fBlibreadline\fP library. When this is done, if the input
+is from a terminal, it is read using the \fBreadline()\fP function. This
+provides line-editing and history facilities. The output from the \fB-help\fP
+option states whether or not \fBreadline()\fP will be used.
+.P
+The program handles any number of sets of input on a single input file. Each
+set starts with a regular expression, and continues with any number of data
+lines to be matched against the pattern.
+.P
+Each data line is matched separately and independently. If you want to do
+multi-line matches, you have to use the \en escape sequence (or \er or \er\en,
+etc., depending on the newline setting) in a single line of input to encode the
+newline sequences. There is no limit on the length of data lines; the input
+buffer is automatically extended if it is too small.
+.P
+An empty line signals the end of the data lines, at which point a new regular
+expression is read. The regular expressions are given enclosed in any
+non-alphanumeric delimiters other than backslash, for example:
+.sp
+  /(a|bc)x+yz/
+.sp
+White space before the initial delimiter is ignored. A regular expression may
+be continued over several input lines, in which case the newline characters are
+included within it. It is possible to include the delimiter within the pattern
+by escaping it, for example
+.sp
+  /abc\e/def/
+.sp
+If you do so, the escape and the delimiter form part of the pattern, but since
+delimiters are always non-alphanumeric, this does not affect its interpretation.
+If the terminating delimiter is immediately followed by a backslash, for
+example,
+.sp
+  /abc/\e
+.sp
+then a backslash is added to the end of the pattern. This is done to provide a
+way of testing the error condition that arises if a pattern finishes with a
+backslash, because
+.sp
+  /abc\e/
+.sp
+is interpreted as the first line of a pattern that starts with "abc/", causing
+pcretest to read the next line as a continuation of the regular expression.
+.
+.
+.SH "PATTERN MODIFIERS"
+.rs
+.sp
+A pattern may be followed by any number of modifiers, which are mostly single
+characters. Following Perl usage, these are referred to below as, for example,
+"the \fB/i\fP modifier", even though the delimiter of the pattern need not
+always be a slash, and no slash is used when writing modifiers. Whitespace may
+appear between the final pattern delimiter and the first modifier, and between
+the modifiers themselves.
+.P
+The \fB/i\fP, \fB/m\fP, \fB/s\fP, and \fB/x\fP modifiers set the PCRE_CASELESS,
+PCRE_MULTILINE, PCRE_DOTALL, or PCRE_EXTENDED options, respectively, when
+\fBpcre_compile()\fP is called. These four modifier letters have the same
+effect as they do in Perl. For example:
+.sp
+  /caseless/i
+.sp
+The following table shows additional modifiers for setting PCRE options that do
+not correspond to anything in Perl:
+.sp
+  \fB/A\fP              PCRE_ANCHORED
+  \fB/C\fP              PCRE_AUTO_CALLOUT
+  \fB/E\fP              PCRE_DOLLAR_ENDONLY
+  \fB/f\fP              PCRE_FIRSTLINE
+  \fB/J\fP              PCRE_DUPNAMES
+  \fB/N\fP              PCRE_NO_AUTO_CAPTURE
+  \fB/U\fP              PCRE_UNGREEDY
+  \fB/X\fP              PCRE_EXTRA
+  \fB/\fP           PCRE_JAVASCRIPT_COMPAT
+  \fB/\fP           PCRE_NEWLINE_CR
+  \fB/\fP           PCRE_NEWLINE_LF
+  \fB/\fP         PCRE_NEWLINE_CRLF
+  \fB/\fP      PCRE_NEWLINE_ANYCRLF
+  \fB/\fP          PCRE_NEWLINE_ANY
+  \fB/\fP  PCRE_BSR_ANYCRLF
+  \fB/\fP  PCRE_BSR_UNICODE
+.sp
+Those specifying line ending sequences are literal strings as shown, but the
+letters can be in either case. This example sets multiline matching with CRLF
+as the line ending sequence:
+.sp
+  /^abc/m
+.sp
+Details of the meanings of these PCRE options are given in the
+.\" HREF
+\fBpcreapi\fP
+.\"
+documentation.
+.
+.
+.SS "Finding all matches in a string"
+.rs
+.sp
+Searching for all possible matches within each subject string can be requested
+by the \fB/g\fP or \fB/G\fP modifier. After finding a match, PCRE is called
+again to search the remainder of the subject string. The difference between
+\fB/g\fP and \fB/G\fP is that the former uses the \fIstartoffset\fP argument to
+\fBpcre_exec()\fP to start searching at a new point within the entire string
+(which is in effect what Perl does), whereas the latter passes over a shortened
+substring. This makes a difference to the matching process if the pattern
+begins with a lookbehind assertion (including \eb or \eB).
+.P
+If any call to \fBpcre_exec()\fP in a \fB/g\fP or \fB/G\fP sequence matches an
+empty string, the next call is done with the PCRE_NOTEMPTY_ATSTART and
+PCRE_ANCHORED flags set in order to search for another, non-empty, match at the
+same point. If this second match fails, the start offset is advanced by one
+character, and the normal match is retried. This imitates the way Perl handles
+such cases when using the \fB/g\fP modifier or the \fBsplit()\fP function.
+.
+.
+.SS "Other modifiers"
+.rs
+.sp
+There are yet more modifiers for controlling the way \fBpcretest\fP
+operates.
+.P
+The \fB/+\fP modifier requests that as well as outputting the substring that
+matched the entire pattern, pcretest should in addition output the remainder of
+the subject string. This is useful for tests where the subject contains
+multiple copies of the same substring.
+.P
+The \fB/B\fP modifier is a debugging feature. It requests that \fBpcretest\fP
+output a representation of the compiled byte code after compilation. Normally
+this information contains length and offset values; however, if \fB/Z\fP is
+also present, this data is replaced by spaces. This is a special feature for
+use in the automatic test scripts; it ensures that the same output is generated
+for different internal link sizes.
+.P
+The \fB/L\fP modifier must be followed directly by the name of a locale, for
+example,
+.sp
+  /pattern/Lfr_FR
+.sp
+For this reason, it must be the last modifier. The given locale is set,
+\fBpcre_maketables()\fP is called to build a set of character tables for the
+locale, and this is then passed to \fBpcre_compile()\fP when compiling the
+regular expression. Without an \fB/L\fP modifier, NULL is passed as the tables
+pointer; that is, \fB/L\fP applies only to the expression on which it appears.
+.P
+The \fB/I\fP modifier requests that \fBpcretest\fP output information about the
+compiled pattern (whether it is anchored, has a fixed first character, and
+so on). It does this by calling \fBpcre_fullinfo()\fP after compiling a
+pattern. If the pattern is studied, the results of that are also output.
+.P
+The \fB/D\fP modifier is a PCRE debugging feature, and is equivalent to
+\fB/BI\fP, that is, both the \fB/B\fP and the \fB/I\fP modifiers.
+.P
+The \fB/F\fP modifier causes \fBpcretest\fP to flip the byte order of the
+fields in the compiled pattern that contain 2-byte and 4-byte numbers. This
+facility is for testing the feature in PCRE that allows it to execute patterns
+that were compiled on a host with a different endianness. This feature is not
+available when the POSIX interface to PCRE is being used, that is, when the
+\fB/P\fP pattern modifier is specified. See also the section about saving and
+reloading compiled patterns below.
+.P
+The \fB/S\fP modifier causes \fBpcre_study()\fP to be called after the
+expression has been compiled, and the results used when the expression is
+matched.
+.P
+The \fB/M\fP modifier causes the size of memory block used to hold the compiled
+pattern to be output.
+.P
+The \fB/P\fP modifier causes \fBpcretest\fP to call PCRE via the POSIX wrapper
+API rather than its native API. When this is done, all other modifiers except
+\fB/i\fP, \fB/m\fP, and \fB/+\fP are ignored. REG_ICASE is set if \fB/i\fP is
+present, and REG_NEWLINE is set if \fB/m\fP is present. The wrapper functions
+force PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set.
+.P
+The \fB/8\fP modifier causes \fBpcretest\fP to call PCRE with the PCRE_UTF8
+option set. This turns on support for UTF-8 character handling in PCRE,
+provided that it was compiled with this support enabled. This modifier also
+causes any non-printing characters in output strings to be printed using the
+\ex{hh...} notation if they are valid UTF-8 sequences.
+.P
+If the \fB/?\fP modifier is used with \fB/8\fP, it causes \fBpcretest\fP to
+call \fBpcre_compile()\fP with the PCRE_NO_UTF8_CHECK option, to suppress the
+checking of the string for UTF-8 validity.
+.
+.
+.SH "DATA LINES"
+.rs
+.sp
+Before each data line is passed to \fBpcre_exec()\fP, leading and trailing
+whitespace is removed, and it is then scanned for \e escapes. Some of these are
+pretty esoteric features, intended for checking out some of the more
+complicated features of PCRE. If you are just testing "ordinary" regular
+expressions, you probably don't need any of these. The following escapes are
+recognized:
+.sp
+  \ea         alarm (BEL, \ex07)
+  \eb         backspace (\ex08)

+.sp
+The escapes that specify line ending sequences are literal strings, exactly as
+shown. No more than one newline setting should be present in any data line.
+.P
+A backslash followed by anything else just escapes the anything else. If
+the very last character is a backslash, it is ignored. This gives a way of
+passing an empty line as data, since a real empty line terminates the data
+input.
+.P
+If \eM is present, \fBpcretest\fP calls \fBpcre_exec()\fP several times, with
+different values in the \fImatch_limit\fP and \fImatch_limit_recursion\fP
+fields of the \fBpcre_extra\fP data structure, until it finds the minimum
+numbers for each parameter that allow \fBpcre_exec()\fP to complete. The
+\fImatch_limit\fP number is a measure of the amount of backtracking that takes
+place, and checking it out can be instructive. For most simple matches, the
+number is quite small, but for patterns with very large numbers of matching
+possibilities, it can become large very quickly with increasing length of
+subject string. The \fImatch_limit_recursion\fP number is a measure of how much
+stack (or, if PCRE is compiled with NO_RECURSE, how much heap) memory is needed
+to complete the match attempt.
+.P
+When \eO is used, the value specified may be higher or lower than the size set
+by the \fB-O\fP command line option (or defaulted to 45); \eO applies only to
+the call of \fBpcre_exec()\fP for the line in which it appears.
+.P
+If the \fB/P\fP modifier was present on the pattern, causing the POSIX wrapper
+API to be used, the only option-setting sequences that have any effect are \eB
+and \eZ, causing REG_NOTBOL and REG_NOTEOL, respectively, to be passed to
+\fBregexec()\fP.
+.P
+The use of \ex{hh...} to represent UTF-8 characters is not dependent on the use
+of the \fB/8\fP modifier on the pattern. It is recognized always. There may be
+any number of hexadecimal digits inside the braces. The result is from one to
+six bytes, encoded according to the original UTF-8 rules of RFC 2279. This
+allows for values in the range 0 to 0x7FFFFFFF. Note that not all of those are
+valid Unicode code points, or indeed valid UTF-8 characters according to the
+later rules in RFC 3629.
+.
+.
+.SH "THE ALTERNATIVE MATCHING FUNCTION"
+.rs
+.sp
+By default, \fBpcretest\fP uses the standard PCRE matching function,
+\fBpcre_exec()\fP to match each data line. From release 6.0, PCRE supports an
+alternative matching function, \fBpcre_dfa_test()\fP, which operates in a
+different way, and has some restrictions. The differences between the two
+functions are described in the
+.\" HREF
+\fBpcrematching\fP
+.\"
+documentation.
+.P
+If a data line contains the \eD escape sequence, or if the command line
+contains the \fB-dfa\fP option, the alternative matching function is called.
+This function finds all possible matches at a given point. If, however, the \eF
+escape sequence is present in the data line, it stops after the first match is
+found. This is always the shortest possible match.
+.
+.
+.SH "DEFAULT OUTPUT FROM PCRETEST"
+.rs
+.sp
+This section describes the output when the normal matching function,
+\fBpcre_exec()\fP, is being used.
+.P
+When a match succeeds, pcretest outputs the list of captured substrings that
+\fBpcre_exec()\fP returns, starting with number 0 for the string that matched
+the whole pattern. Otherwise, it outputs "No match" when the return is
+PCRE_ERROR_NOMATCH, and "Partial match:" followed by the partially matching
+substring when \fBpcre_exec()\fP returns PCRE_ERROR_PARTIAL. For any other
+returns, it outputs the PCRE negative error number. Here is an example of an
+interactive \fBpcretest\fP run.
+.sp
+  $ pcretest
+  PCRE version 7.0 30-Nov-2006
+.sp
+    re> /^abc(\ed+)/
+  data> abc123
+   0: abc123
+   1: 123
+  data> xyz
+  No match
+.sp
+Note that unset capturing substrings that are not followed by one that is set
+are not returned by \fBpcre_exec()\fP, and are not shown by \fBpcretest\fP. In
+the following example, there are two capturing substrings, but when the first
+data line is matched, the second, unset substring is not shown. An "internal"
+unset substring is shown as "", as for the second data line.
+.sp
+    re> /(a)|(b)/
+  data> a
+   0: a
+   1: a
+  data> b
+   0: b
+   1: 
+   2: b
+.sp
+If the strings contain any non-printing characters, they are output as \e0x
+escapes, or as \ex{...} escapes if the \fB/8\fP modifier was present on the
+pattern. See below for the definition of non-printing characters. If the
+pattern has the \fB/+\fP modifier, the output for substring 0 is followed by
+the the rest of the subject string, identified by "0+" like this:
+.sp
+    re> /cat/+
+  data> cataract
+   0: cat
+   0+ aract
+.sp
+If the pattern has the \fB/g\fP or \fB/G\fP modifier, the results of successive
+matching attempts are output in sequence, like this:
+.sp
+    re> /\eBi(\ew\ew)/g
+  data> Mississippi
+   0: iss
+   1: ss
+   0: iss
+   1: ss
+   0: ipp
+   1: pp
+.sp
+"No match" is output only if the first match attempt fails.
+.P
+If any of the sequences \fB\eC\fP, \fB\eG\fP, or \fB\eL\fP are present in a
+data line that is successfully matched, the substrings extracted by the
+convenience functions are output with C, G, or L after the string number
+instead of a colon. This is in addition to the normal full list. The string
+length (that is, the return from the extraction function) is given in
+parentheses after each string for \fB\eC\fP and \fB\eG\fP.
+.P
+Note that whereas patterns can be continued over several lines (a plain ">"
+prompt is used for continuations), data lines may not. However newlines can be
+included in data by means of the \en escape (or \er, \er\en, etc., depending on
+the newline sequence setting).
+.
+.
+.
+.SH "OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION"
+.rs
+.sp
+When the alternative matching function, \fBpcre_dfa_exec()\fP, is used (by
+means of the \eD escape sequence or the \fB-dfa\fP command line option), the
+output consists of a list of all the matches that start at the first point in
+the subject where there is at least one match. For example:
+.sp
+    re> /(tang|tangerine|tan)/
+  data> yellow tangerine\eD
+   0: tangerine
+   1: tang
+   2: tan
+.sp
+(Using the normal matching function on this data finds only "tang".) The
+longest matching string is always given first (and numbered zero). After a
+PCRE_ERROR_PARTIAL return, the output is "Partial match:", followed by the
+partially matching substring.
+.P
+If \fB/g\fP is present on the pattern, the search for further matches resumes
+at the end of the longest match. For example:
+.sp
+    re> /(tang|tangerine|tan)/g
+  data> yellow tangerine and tangy sultana\eD
+   0: tangerine
+   1: tang
+   2: tan
+   0: tang
+   1: tan
+   0: tan
+.sp
+Since the matching function does not support substring capture, the escape
+sequences that are concerned with captured substrings are not relevant.
+.
+.
+.SH "RESTARTING AFTER A PARTIAL MATCH"
+.rs
+.sp
+When the alternative matching function has given the PCRE_ERROR_PARTIAL return,
+indicating that the subject partially matched the pattern, you can restart the
+match with additional subject data by means of the \eR escape sequence. For
+example:
+.sp
+    re> /^\ed?\ed(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\ed\ed$/
+  data> 23ja\eP\eD
+  Partial match: 23ja
+  data> n05\eR\eD
+   0: n05
+.sp
+For further information about partial matching, see the
+.\" HREF
+\fBpcrepartial\fP
+.\"
+documentation.
+.
+.
+.SH CALLOUTS
+.rs
+.sp
+If the pattern contains any callout requests, \fBpcretest\fP's callout function
+is called during matching. This works with both matching functions. By default,
+the called function displays the callout number, the start and current
+positions in the text at the callout time, and the next pattern item to be
+tested. For example, the output
+.sp
+  --->pqrabcdef
+    0    ^  ^     \ed
+.sp
+indicates that callout number 0 occurred for a match attempt starting at the
+fourth character of the subject string, when the pointer was at the seventh
+character of the data, and when the next pattern item was \ed. Just one
+circumflex is output if the start and current positions are the same.
+.P
+Callouts numbered 255 are assumed to be automatic callouts, inserted as a
+result of the \fB/C\fP pattern modifier. In this case, instead of showing the
+callout number, the offset in the pattern, preceded by a plus, is output. For
+example:
+.sp
+    re> /\ed?[A-E]\e*/C
+  data> E*
+  --->E*
+   +0 ^      \ed?
+   +3 ^      [A-E]
+   +8 ^^     \e*
+  +10 ^ ^
+   0: E*
+.sp
+The callout function in \fBpcretest\fP returns zero (carry on matching) by
+default, but you can use a \eC item in a data line (as described above) to
+change this.
+.P
+Inserting callouts can be helpful when using \fBpcretest\fP to check
+complicated regular expressions. For further information about callouts, see
+the
+.\" HREF
+\fBpcrecallout\fP
+.\"
+documentation.
+.
+.
+.
+.SH "NON-PRINTING CHARACTERS"
+.rs
+.sp
+When \fBpcretest\fP is outputting text in the compiled version of a pattern,
+bytes other than 32-126 are always treated as non-printing characters are are
+therefore shown as hex escapes.
+.P
+When \fBpcretest\fP is outputting text that is a matched part of a subject
+string, it behaves in the same way, unless a different locale has been set for
+the pattern (using the \fB/L\fP modifier). In this case, the \fBisprint()\fP
+function to distinguish printing and non-printing characters.
+.
+.
+.
+.SH "SAVING AND RELOADING COMPILED PATTERNS"
+.rs
+.sp
+The facilities described in this section are not available when the POSIX
+inteface to PCRE is being used, that is, when the \fB/P\fP pattern modifier is
+specified.
+.P
+When the POSIX interface is not in use, you can cause \fBpcretest\fP to write a
+compiled pattern to a file, by following the modifiers with > and a file name.
+For example:
+.sp
+  /pattern/im >/some/file
+.sp
+See the
+.\" HREF
+\fBpcreprecompile\fP
+.\"
+documentation for a discussion about saving and re-using compiled patterns.
+.P
+The data that is written is binary. The first eight bytes are the length of the
+compiled pattern data followed by the length of the optional study data, each
+written as four bytes in big-endian order (most significant byte first). If
+there is no study data (either the pattern was not studied, or studying did not
+return any data), the second length is zero. The lengths are followed by an
+exact copy of the compiled pattern. If there is additional study data, this
+follows immediately after the compiled pattern. After writing the file,
+\fBpcretest\fP expects to read a new pattern.
+.P
+A saved pattern can be reloaded into \fBpcretest\fP by specifing < and a file
+name instead of a pattern. The name of the file must not contain a < character,
+as otherwise \fBpcretest\fP will interpret the line as a pattern delimited by <
+characters.
+For example:
+.sp
+   re> " to prompt for regular expressions, and "data>" to prompt for data
+       lines.
+
+       When pcretest is built, a configuration  option  can  specify  that  it
+       should  be  linked  with the libreadline library. When this is done, if
+       the input is from a terminal, it is read using the readline() function.
+       This  provides line-editing and history facilities. The output from the
+       -help option states whether or not readline() will be used.
+
+       The program handles any number of sets of input on a single input file.
+       Each  set starts with a regular expression, and continues with any num-
+       ber of data lines to be matched against the pattern.
+
+       Each data line is matched separately and independently. If you want  to
+       do multi-line matches, you have to use the \n escape sequence (or \r or
+       \r\n, etc., depending on the newline setting) in a single line of input
+       to  encode  the  newline  sequences. There is no limit on the length of
+       data lines; the input buffer is automatically extended  if  it  is  too
+       small.
+
+       An  empty  line signals the end of the data lines, at which point a new
+       regular expression is read. The regular expressions are given  enclosed
+       in any non-alphanumeric delimiters other than backslash, for example:
+
+         /(a|bc)x+yz/
+
+       White  space before the initial delimiter is ignored. A regular expres-
+       sion may be continued over several input lines, in which case the  new-
+       line  characters  are included within it. It is possible to include the
+       delimiter within the pattern by escaping it, for example
+
+         /abc\/def/
+
+       If you do so, the escape and the delimiter form part  of  the  pattern,
+       but  since delimiters are always non-alphanumeric, this does not affect
+       its interpretation.  If the terminating delimiter is  immediately  fol-
+       lowed by a backslash, for example,
+
+         /abc/\
+
+       then  a  backslash  is added to the end of the pattern. This is done to
+       provide a way of testing the error condition that arises if  a  pattern
+       finishes with a backslash, because
+
+         /abc\/
+
+       is  interpreted as the first line of a pattern that starts with "abc/",
+       causing pcretest to read the next line as a continuation of the regular
+       expression.
+
+
+PATTERN MODIFIERS
+
+       A  pattern may be followed by any number of modifiers, which are mostly
+       single characters. Following Perl usage, these are  referred  to  below
+       as,  for  example,  "the /i modifier", even though the delimiter of the
+       pattern need not always be a slash, and no slash is used  when  writing
+       modifiers.  Whitespace  may  appear between the final pattern delimiter
+       and the first modifier, and between the modifiers themselves.
+
+       The /i, /m, /s, and /x modifiers set the PCRE_CASELESS, PCRE_MULTILINE,
+       PCRE_DOTALL,  or  PCRE_EXTENDED  options,  respectively, when pcre_com-
+       pile() is called. These four modifier letters have the same  effect  as
+       they do in Perl. For example:
+
+         /caseless/i
+
+       The following table shows additional modifiers for setting PCRE options
+       that do not correspond to anything in Perl:
+
+         /A              PCRE_ANCHORED
+         /C              PCRE_AUTO_CALLOUT
+         /E              PCRE_DOLLAR_ENDONLY
+         /f              PCRE_FIRSTLINE
+         /J              PCRE_DUPNAMES
+         /N              PCRE_NO_AUTO_CAPTURE
+         /U              PCRE_UNGREEDY
+         /X              PCRE_EXTRA
+         /           PCRE_JAVASCRIPT_COMPAT
+         /           PCRE_NEWLINE_CR
+         /           PCRE_NEWLINE_LF
+         /         PCRE_NEWLINE_CRLF
+         /      PCRE_NEWLINE_ANYCRLF
+         /          PCRE_NEWLINE_ANY
+         /  PCRE_BSR_ANYCRLF
+         /  PCRE_BSR_UNICODE
+
+       Those specifying line ending sequences are literal  strings  as  shown,
+       but  the  letters  can  be  in either case. This example sets multiline
+       matching with CRLF as the line ending sequence:
+
+         /^abc/m
+
+       Details of the meanings of these PCRE options are given in the  pcreapi
+       documentation.
+
+   Finding all matches in a string
+
+       Searching  for  all  possible matches within each subject string can be
+       requested by the /g or /G modifier. After  finding  a  match,  PCRE  is
+       called again to search the remainder of the subject string. The differ-
+       ence between /g and /G is that the former uses the startoffset argument
+       to  pcre_exec()  to  start  searching  at a new point within the entire
+       string (which is in effect what Perl does), whereas the  latter  passes
+       over  a  shortened  substring.  This makes a difference to the matching
+       process if the pattern begins with a lookbehind assertion (including \b
+       or \B).
+
+       If  any  call  to  pcre_exec()  in a /g or /G sequence matches an empty
+       string, the next  call  is  done  with  the  PCRE_NOTEMPTY_ATSTART  and
+       PCRE_ANCHORED  flags  set  in  order  to search for another, non-empty,
+       match at the same point. If this second match fails, the  start  offset
+       is  advanced  by  one  character, and the normal match is retried. This
+       imitates the way Perl handles such cases when using the /g modifier  or
+       the split() function.
+
+   Other modifiers
+
+       There are yet more modifiers for controlling the way pcretest operates.
+
+       The  /+ modifier requests that as well as outputting the substring that
+       matched the entire pattern, pcretest  should  in  addition  output  the
+       remainder  of  the  subject  string. This is useful for tests where the
+       subject contains multiple copies of the same substring.
+
+       The /B modifier is a debugging feature. It requests that pcretest  out-
+       put  a representation of the compiled byte code after compilation. Nor-
+       mally this information contains length and offset values;  however,  if
+       /Z  is also present, this data is replaced by spaces. This is a special
+       feature for use in the automatic test scripts; it ensures that the same
+       output is generated for different internal link sizes.
+
+       The  /L modifier must be followed directly by the name of a locale, for
+       example,
+
+         /pattern/Lfr_FR
+
+       For this reason, it must be the last modifier. The given locale is set,
+       pcre_maketables()  is called to build a set of character tables for the
+       locale, and this is then passed to pcre_compile()  when  compiling  the
+       regular  expression.  Without  an  /L  modifier,  NULL is passed as the
+       tables pointer; that is, /L applies only to the expression on which  it
+       appears.
+
+       The  /I  modifier  requests  that pcretest output information about the
+       compiled pattern (whether it is anchored, has a fixed first  character,
+       and  so  on). It does this by calling pcre_fullinfo() after compiling a
+       pattern. If the pattern is studied, the results of that are  also  out-
+       put.
+
+       The  /D modifier is a PCRE debugging feature, and is equivalent to /BI,
+       that is, both the /B and the /I modifiers.
+
+       The /F modifier causes pcretest to flip the byte order of the fields in
+       the  compiled  pattern  that  contain  2-byte  and 4-byte numbers. This
+       facility is for testing the feature in PCRE that allows it  to  execute
+       patterns that were compiled on a host with a different endianness. This
+       feature is not available when the POSIX  interface  to  PCRE  is  being
+       used,  that is, when the /P pattern modifier is specified. See also the
+       section about saving and reloading compiled patterns below.
+
+       The /S modifier causes pcre_study() to be called after  the  expression
+       has been compiled, and the results used when the expression is matched.
+
+       The  /M  modifier causes the size of memory block used to hold the com-
+       piled pattern to be output.
+
+       The /P modifier causes pcretest to call PCRE via the POSIX wrapper  API
+       rather  than  its  native  API.  When this is done, all other modifiers
+       except /i, /m, and /+ are ignored. REG_ICASE is set if /i  is  present,
+       and  REG_NEWLINE  is  set if /m is present. The wrapper functions force
+       PCRE_DOLLAR_ENDONLY always, and PCRE_DOTALL unless REG_NEWLINE is set.
+
+       The /8 modifier causes pcretest to call PCRE with the PCRE_UTF8  option
+       set.  This  turns on support for UTF-8 character handling in PCRE, pro-
+       vided that it was compiled with this  support  enabled.  This  modifier
+       also causes any non-printing characters in output strings to be printed
+       using the \x{hh...} notation if they are valid UTF-8 sequences.
+
+       If the /? modifier  is  used  with  /8,  it  causes  pcretest  to  call
+       pcre_compile()  with  the  PCRE_NO_UTF8_CHECK  option,  to suppress the
+       checking of the string for UTF-8 validity.
+
+
+DATA LINES
+
+       Before each data line is passed to pcre_exec(),  leading  and  trailing
+       whitespace  is  removed,  and it is then scanned for \ escapes. Some of
+       these are pretty esoteric features, intended for checking out  some  of
+       the  more  complicated features of PCRE. If you are just testing "ordi-
+       nary" regular expressions, you probably don't need any  of  these.  The
+       following escapes are recognized:
+
+         \a         alarm (BEL, \x07)
+         \b         backspace (\x08)
+         \e         escape (\x27)
+         \f         formfeed (\x0c)

+         \qdd       set the PCRE_MATCH_LIMIT limit to dd

+         \t         tab (\x09)

+         \nnn       octal character (up to 3 octal digits)
+         \xhh       hexadecimal character (up to 2 hex digits)

+         \Odd       set the size of the output vector passed to

+         \P         pass the PCRE_PARTIAL_SOFT option to pcre_exec()

+         \S         output details of memory get/free calls during matching
+         \Y         pass the PCRE_NO_START_OPTIMIZE option to pcre_exec()
+                      or pcre_dfa_exec()
+         \Z         pass the PCRE_NOTEOL option to pcre_exec()
+                      or pcre_dfa_exec()
+         \?         pass the PCRE_NO_UTF8_CHECK option to
+                      pcre_exec() or pcre_dfa_exec()
+         \>dd       start the match at offset dd (any number of digits);
+                      this sets the startoffset argument for pcre_exec()
+                      or pcre_dfa_exec()
+         \      pass the PCRE_NEWLINE_CR option to pcre_exec()
+                      or pcre_dfa_exec()
+         \      pass the PCRE_NEWLINE_LF option to pcre_exec()
+                      or pcre_dfa_exec()
+         \    pass the PCRE_NEWLINE_CRLF option to pcre_exec()
+                      or pcre_dfa_exec()
+         \ pass the PCRE_NEWLINE_ANYCRLF option to pcre_exec()
+                      or pcre_dfa_exec()
+         \     pass the PCRE_NEWLINE_ANY option to pcre_exec()
+                      or pcre_dfa_exec()
+
+       The  escapes  that  specify  line ending sequences are literal strings,
+       exactly as shown. No more than one newline setting should be present in
+       any data line.
+
+       A  backslash  followed by anything else just escapes the anything else.
+       If the very last character is a backslash, it is ignored. This gives  a
+       way  of  passing  an empty line as data, since a real empty line termi-
+       nates the data input.
+
+       If \M is present, pcretest calls pcre_exec() several times,  with  dif-
+       ferent  values  in  the match_limit and match_limit_recursion fields of
+       the pcre_extra data structure, until it finds the minimum  numbers  for
+       each parameter that allow pcre_exec() to complete. The match_limit num-
+       ber is a measure of the amount of backtracking that  takes  place,  and
+       checking it out can be instructive. For most simple matches, the number
+       is quite small, but for patterns with very large  numbers  of  matching
+       possibilities,  it can become large very quickly with increasing length
+       of subject string. The match_limit_recursion number is a measure of how
+       much  stack  (or,  if  PCRE is compiled with NO_RECURSE, how much heap)
+       memory is needed to complete the match attempt.
+
+       When \O is used, the value specified may be higher or  lower  than  the
+       size set by the -O command line option (or defaulted to 45); \O applies
+       only to the call of pcre_exec() for the line in which it appears.
+
+       If the /P modifier was present on the pattern, causing the POSIX  wrap-
+       per  API  to  be  used, the only option-setting sequences that have any
+       effect are \B and \Z, causing REG_NOTBOL and REG_NOTEOL,  respectively,
+       to be passed to regexec().
+
+       The  use of \x{hh...} to represent UTF-8 characters is not dependent on
+       the use of the /8 modifier on the pattern.  It  is  recognized  always.
+       There  may  be  any number of hexadecimal digits inside the braces. The
+       result is from one to six bytes,  encoded  according  to  the  original
+       UTF-8  rules  of  RFC  2279.  This  allows for values in the range 0 to
+       0x7FFFFFFF. Note that not all of those are valid Unicode  code  points,
+       or  indeed  valid  UTF-8 characters according to the later rules in RFC
+       3629.
+
+
+THE ALTERNATIVE MATCHING FUNCTION
+
+       By  default,  pcretest  uses  the  standard  PCRE  matching   function,
+       pcre_exec() to match each data line. From release 6.0, PCRE supports an
+       alternative matching function, pcre_dfa_test(),  which  operates  in  a
+       different  way,  and has some restrictions. The differences between the
+       two functions are described in the pcrematching documentation.
+
+       If a data line contains the \D escape sequence, or if the command  line
+       contains  the -dfa option, the alternative matching function is called.
+       This function finds all possible matches at a given point. If, however,
+       the  \F escape sequence is present in the data line, it stops after the
+       first match is found. This is always the shortest possible match.
+
+
+DEFAULT OUTPUT FROM PCRETEST
+
+       This section describes the output when the  normal  matching  function,
+       pcre_exec(), is being used.
+
+       When a match succeeds, pcretest outputs the list of captured substrings
+       that pcre_exec() returns, starting with number 0 for  the  string  that
+       matched  the  whole  pattern. Otherwise, it outputs "No match" when the
+       return is PCRE_ERROR_NOMATCH, and "Partial match:" followed by the par-
+       tially  matching substring when pcre_exec() returns PCRE_ERROR_PARTIAL.
+       For any other returns, it outputs the PCRE negative error number.  Here
+       is an example of an interactive pcretest run.
+
+         $ pcretest
+         PCRE version 7.0 30-Nov-2006
+
+           re> /^abc(\d+)/
+         data> abc123
+          0: abc123
+          1: 123
+         data> xyz
+         No match
+
+       Note  that unset capturing substrings that are not followed by one that
+       is set are not returned by pcre_exec(), and are not shown by  pcretest.
+       In  the following example, there are two capturing substrings, but when
+       the first data line is matched, the  second,  unset  substring  is  not
+       shown.  An "internal" unset substring is shown as "", as for the
+       second data line.
+
+           re> /(a)|(b)/
+         data> a
+          0: a
+          1: a
+         data> b
+          0: b
+          1: 
+          2: b
+
+       If the strings contain any non-printing characters, they are output  as
+       \0x  escapes,  or  as \x{...} escapes if the /8 modifier was present on
+       the pattern. See below for the definition of  non-printing  characters.
+       If  the pattern has the /+ modifier, the output for substring 0 is fol-
+       lowed by the the rest of the subject string, identified  by  "0+"  like
+       this:
+
+           re> /cat/+
+         data> cataract
+          0: cat
+          0+ aract
+
+       If  the  pattern  has  the /g or /G modifier, the results of successive
+       matching attempts are output in sequence, like this:
+
+           re> /\Bi(\w\w)/g
+         data> Mississippi
+          0: iss
+          1: ss
+          0: iss
+          1: ss
+          0: ipp
+          1: pp
+
+       "No match" is output only if the first match attempt fails.
+
+       If any of the sequences \C, \G, or \L are present in a data  line  that
+       is  successfully  matched,  the substrings extracted by the convenience
+       functions are output with C, G, or L after the string number instead of
+       a colon. This is in addition to the normal full list. The string length
+       (that is, the return from the extraction function) is given  in  paren-
+       theses after each string for \C and \G.
+
+       Note that whereas patterns can be continued over several lines (a plain
+       ">" prompt is used for continuations), data lines may not. However new-
+       lines  can  be included in data by means of the \n escape (or \r, \r\n,
+       etc., depending on the newline sequence setting).
+
+
+OUTPUT FROM THE ALTERNATIVE MATCHING FUNCTION
+
+       When the alternative matching function, pcre_dfa_exec(),  is  used  (by
+       means  of  the \D escape sequence or the -dfa command line option), the
+       output consists of a list of all the matches that start  at  the  first
+       point in the subject where there is at least one match. For example:
+
+           re> /(tang|tangerine|tan)/
+         data> yellow tangerine\D
+          0: tangerine
+          1: tang
+          2: tan
+
+       (Using  the  normal  matching function on this data finds only "tang".)
+       The longest matching string is always given first (and numbered  zero).
+       After a PCRE_ERROR_PARTIAL return, the output is "Partial match:", fol-
+       lowed by the partially matching substring.
+
+       If /g is present on the pattern, the search for further matches resumes
+       at the end of the longest match. For example:
+
+           re> /(tang|tangerine|tan)/g
+         data> yellow tangerine and tangy sultana\D
+          0: tangerine
+          1: tang
+          2: tan
+          0: tang
+          1: tan
+          0: tan
+
+       Since  the  matching  function  does not support substring capture, the
+       escape sequences that are concerned with captured  substrings  are  not
+       relevant.

+       When the alternative matching function has given the PCRE_ERROR_PARTIAL
+       return, indicating that the subject partially matched the pattern,  you
+       can  restart  the match with additional subject data by means of the \R
+       escape sequence. For example:
+
+           re> /^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$/
+         data> 23ja\P\D
+         Partial match: 23ja
+         data> n05\R\D
+          0: n05
+
+       For further information about partial  matching,  see  the  pcrepartial
+       documentation.
+
+
+CALLOUTS
+
+       If  the pattern contains any callout requests, pcretest's callout func-
+       tion is called during matching. This works  with  both  matching  func-
+       tions. By default, the called function displays the callout number, the
+       start and current positions in the text at the callout  time,  and  the
+       next pattern item to be tested. For example, the output
+
+         --->pqrabcdef
+           0    ^  ^     \d
+
+       indicates  that  callout number 0 occurred for a match attempt starting
+       at the fourth character of the subject string, when the pointer was  at
+       the  seventh  character of the data, and when the next pattern item was
+       \d. Just one circumflex is output if the start  and  current  positions
+       are the same.
+
+       Callouts numbered 255 are assumed to be automatic callouts, inserted as
+       a result of the /C pattern modifier. In this case, instead  of  showing
+       the  callout  number, the offset in the pattern, preceded by a plus, is
+       output. For example:
+
+           re> /\d?[A-E]\*/C
+         data> E*
+         --->E*
+          +0 ^      \d?
+          +3 ^      [A-E]
+          +8 ^^     \*
+         +10 ^ ^
+          0: E*
+
+       The callout function in pcretest returns zero (carry  on  matching)  by
+       default,  but you can use a \C item in a data line (as described above)
+       to change this.
+
+       Inserting callouts can be helpful when using pcretest to check  compli-
+       cated  regular expressions. For further information about callouts, see
+       the pcrecallout documentation.
+
+
+NON-PRINTING CHARACTERS
+
+       When pcretest is outputting text in the compiled version of a  pattern,
+       bytes  other  than 32-126 are always treated as non-printing characters
+       are are therefore shown as hex escapes.
+
+       When pcretest is outputting text that is a matched part  of  a  subject
+       string,  it behaves in the same way, unless a different locale has been
+       set for the  pattern  (using  the  /L  modifier).  In  this  case,  the
+       isprint() function to distinguish printing and non-printing characters.
+
+
+SAVING AND RELOADING COMPILED PATTERNS
+
+       The  facilities  described  in  this section are not available when the
+       POSIX inteface to PCRE is being used, that is, when the /P pattern mod-
+       ifier is specified.
+
+       When the POSIX interface is not in use, you can cause pcretest to write
+       a compiled pattern to a file, by following the modifiers with >  and  a
+       file name.  For example:
+
+         /pattern/im >/some/file
+
+       See  the pcreprecompile documentation for a discussion about saving and
+       re-using compiled patterns.
+
+       The data that is written is binary.  The  first  eight  bytes  are  the
+       length  of  the  compiled  pattern  data  followed by the length of the
+       optional study data, each written as four  bytes  in  big-endian  order
+       (most  significant  byte  first). If there is no study data (either the
+       pattern was not studied, or studying did not return any data), the sec-
+       ond  length  is  zero. The lengths are followed by an exact copy of the
+       compiled pattern. If there is additional study data, this follows imme-
+       diately  after  the  compiled pattern. After writing the file, pcretest
+       expects to read a new pattern.
+
+       A saved pattern can be reloaded into pcretest by specifing < and a file
+       name  instead  of  a pattern. The name of the file must not contain a <
+       character, as otherwise pcretest will interpret the line as  a  pattern
+       delimited by < characters.  For example:
+
+          re> &2
+	    exit 1;;
+	esac

+    -o) chowncmd="$chownprog $2"

+# choices, we go for a static library, that is the most portable,
+# since we can't tell whether shared libraries were disabled because
+# the user asked for that or because the platform doesn't support
+# them.  This is particularly important on AIX, because we don't
+# support having both static and shared libraries enabled at the same
+# time on that platform, so we default to a shared-only configuration.
+# If a disable-shared tag is given, we'll fallback to a static-only
+# configuration.  But we'll never go from static-only to shared-only.

+/* This file contains character tables that are used when no external tables
+are passed to PCRE by the application that calls it. The tables are used only
+for characters whose code values are less than 256.
+
+This is a default version of the tables that assumes ASCII encoding. A program
+called dftables (which is distributed with PCRE) can be used to build
+alternative versions of this file. This is necessary if you are running in an
+EBCDIC environment, or if you want to default to a different encoding, for
+example ISO-8859-1. When dftables is run, it creates these tables in the
+current locale. If PCRE is configured with --enable-rebuild-chartables, this
+happens automatically.
+
+The following #includes are present because without the gcc 4.x may remove the
+array definition from the final binary if PCRE is built into a static library
+and dead code stripping is activated. This leads to link errors. Pulling in the
+header ensures that the array gets flagged as "someone outside this compilation
+unit might reference this" and so it will always be supplied to the linker. */

+/* This file contains character tables that are used when no external tables
+are passed to PCRE by the application that calls it. The tables are used only
+for characters whose code values are less than 256.
+
+This is a default version of the tables that assumes ASCII encoding. A program
+called dftables (which is distributed with PCRE) can be used to build
+alternative versions of this file. This is necessary if you are running in an
+EBCDIC environment, or if you want to default to a different encoding, for
+example ISO-8859-1. When dftables is run, it creates these tables in the
+current locale. If PCRE is configured with --enable-rebuild-chartables, this
+happens automatically.
+
+The following #includes are present because without the gcc 4.x may remove the
+array definition from the final binary if PCRE is built into a static library
+and dead code stripping is activated. This leads to link errors. Pulling in the
+header ensures that the array gets flagged as "someone outside this compilation
+unit might reference this" and so it will always be supplied to the linker. */

+/* This module contains the external function pcre_dfa_exec(), which is an
+alternative matching function that uses a sort of DFA algorithm (not a true
+FSM). This is NOT Perl- compatible, but it has advantages in certain
+applications. */
+
+
+/* NOTE ABOUT PERFORMANCE: A user of this function sent some code that improved
+the performance of his patterns greatly. I could not use it as it stood, as it
+was not thread safe, and made assumptions about pattern sizes. Also, it caused
+test 7 to loop, and test 9 to crash with a segfault.
+
+The issue is the check for duplicate states, which is done by a simple linear
+search up the state list. (Grep for "duplicate" below to find the code.) For
+many patterns, there will never be many states active at one time, so a simple
+linear search is fine. In patterns that have many active states, it might be a
+bottleneck. The suggested code used an indexing scheme to remember which states
+had previously been used for each character, and avoided the linear search when
+it knew there was no chance of a duplicate. This was implemented when adding
+states to the state lists.
+
+I wrote some thread-safe, not-limited code to try something similar at the time
+of checking for duplicates (instead of when adding states), using index vectors
+on the stack. It did give a 13% improvement with one specially constructed
+pattern for certain subject strings, but on other strings and on many of the
+simpler patterns in the test suite it did worse. The major problem, I think,
+was the extra time to initialize the index. This had to be done for each call
+of internal_dfa_exec(). (The supplied patch used a static vector, initialized
+only once - I suspect this was the cause of the problems with the tests.)
+
+Overall, I concluded that the gains in some cases did not outweigh the losses
+in others, so I abandoned this code. */

+****************************************************************************
+                   RECURSION IN THE match() FUNCTION
+
+The match() function is highly recursive, though not every recursive call
+increases the recursive depth. Nevertheless, some regular expressions can cause
+it to recurse to a great depth. I was writing for Unix, so I just let it call
+itself recursively. This uses the stack for saving everything that has to be
+saved for a recursive call. On Unix, the stack can be large, and this works
+fine.
+
+It turns out that on some non-Unix-like systems there are problems with
+programs that use a lot of stack. (This despite the fact that every last chip
+has oodles of memory these days, and techniques for extending the stack have
+been known for decades.) So....
+
+There is a fudge, triggered by defining NO_RECURSE, which avoids recursive
+calls by keeping local variables that need to be preserved in blocks of memory
+obtained from malloc() instead instead of on the stack. Macros are used to
+achieve this so that the actual code doesn't look very different to what it
+always used to.
+
+The original heap-recursive code used longjmp(). However, it seems that this
+can be very slow on some operating systems. Following a suggestion from Stan
+Switzer, the use of longjmp() has been abolished, at the cost of having to
+provide a unique number for each call to RMATCH. There is no way of generating
+a sequence of numbers at compile time in C. I have given them names, to make
+them stand out more clearly.
+
+Crude tests on x86 Linux show a small speedup of around 5-8%. However, on
+FreeBSD, avoiding longjmp() more than halves the time taken to run the standard
+tests. Furthermore, not using longjmp() means that local dynamic variables
+don't have indeterminate values; this has meant that the frame size can be
+reduced because the result can be "passed back" by straight setting of the
+variable instead of being passed in the frame.

+http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
+information there, using __declspec(dllexport) without "extern" we have a
+definition; with "extern" we have a declaration. The settings here override the
+setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,

+  PCRE_EXP_DATA_DEFN  for definitions of exported variables
+
+The reason for the two DEFN macros is that in non-Windows environments, one
+does not want to have "extern" before variable definitions because it leads to
+compiler warnings. So we distinguish between functions and variables. In
+Windows, the two should always be the same.
+
+The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
+which is an application, but needs to import this file in order to "peek" at
+internals, can #include pcre.h first to get an application's-eye view.
+
+In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
+special-purpose environments) might want to stick other stuff in front of
+exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and

+
+July 2008: There is now a script called maint/GenerateUtt.py that can be used
+to generate this data instead of maintaining it entirely by hand.
+
+The script was updated in March 2009 to generate a new EBCDIC-compliant
+version. Like all other character and string literals that are compared against
+the regular expression pattern, we must use STR_ macros instead of literal
+strings to make sure that UTF-8 support works on EBCDIC platforms. */

+*         Validate a UTF-8 string                *
+*************************************************/
+
+/* This function is called (optionally) at the start of compile or match, to
+validate that a supposed UTF-8 string is actually valid. The early check means
+that subsequent code can assume it is dealing with a valid string. The check
+can be turned off for maximum performance, but the consequences of supplying
+an invalid string are then undefined.
+
+Originally, this function checked according to RFC 2279, allowing for values in
+the range 0 to 0x7fffffff, up to 6 bytes long, but ensuring that they were in
+the canonical format. Once somebody had pointed out RFC 3629 to me (it
+obsoletes 2279), additional restrictions were applied. The values are now
+limited to be between 0 and 0x0010ffff, no more than 4 bytes long, and the
+subrange 0xd000 to 0xdfff is excluded.
+
+Arguments:
+  string       points to the string
+  length       length of string, or -1 if the string is zero-terminated
+
+Returns:       < 0    if the string is a valid UTF-8 string
+               >= 0   otherwise; the value is the offset of the bad byte

+#ifndef _PCRECPP_H
+#define _PCRECPP_H
+
+// C++ interface to the pcre regular-expression library.  RE supports
+// Perl-style regular expressions (with extensions like \d, \w, \s,
+// ...).
+//
+// -----------------------------------------------------------------------
+// REGEXP SYNTAX:
+//
+// This module is part of the pcre library and hence supports its syntax
+// for regular expressions.
+//
+// The syntax is pretty similar to Perl's.  For those not familiar
+// with Perl's regular expressions, here are some examples of the most
+// commonly used extensions:
+//
+//   "hello (\\w+) world"  -- \w matches a "word" character
+//   "version (\\d+)"      -- \d matches a digit
+//   "hello\\s+world"      -- \s matches any whitespace character
+//   "\\b(\\w+)\\b"        -- \b matches empty string at a word boundary
+//   "(?i)hello"           -- (?i) turns on case-insensitive matching
+//   "/\\*(.*?)\\*/"       -- .*? matches . minimum no. of times possible
+//
+// -----------------------------------------------------------------------
+// MATCHING INTERFACE:
+//
+// The "FullMatch" operation checks that supplied text matches a
+// supplied pattern exactly.
+//
+// Example: successful match
+//    pcrecpp::RE re("h.*o");
+//    re.FullMatch("hello");
+//
+// Example: unsuccessful match (requires full match):
+//    pcrecpp::RE re("e");
+//    !re.FullMatch("hello");
+//
+// Example: creating a temporary RE object:
+//    pcrecpp::RE("h.*o").FullMatch("hello");
+//
+// You can pass in a "const char*" or a "string" for "text".  The
+// examples below tend to use a const char*.
+//
+// You can, as in the different examples above, store the RE object
+// explicitly in a variable or use a temporary RE object.  The
+// examples below use one mode or the other arbitrarily.  Either
+// could correctly be used for any of these examples.
+//
+// -----------------------------------------------------------------------
+// MATCHING WITH SUB-STRING EXTRACTION:
+//
+// You can supply extra pointer arguments to extract matched subpieces.
+//
+// Example: extracts "ruby" into "s" and 1234 into "i"
+//    int i;
+//    string s;
+//    pcrecpp::RE re("(\\w+):(\\d+)");
+//    re.FullMatch("ruby:1234", &s, &i);
+//
+// Example: does not try to extract any extra sub-patterns
+//    re.FullMatch("ruby:1234", &s);
+//
+// Example: does not try to extract into NULL
+//    re.FullMatch("ruby:1234", NULL, &i);
+//
+// Example: integer overflow causes failure
+//    !re.FullMatch("ruby:1234567891234", NULL, &i);
+//
+// Example: fails because there aren't enough sub-patterns:
+//    !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s);
+//
+// Example: fails because string cannot be stored in integer
+//    !pcrecpp::RE("(.*)").FullMatch("ruby", &i);
+//
+// The provided pointer arguments can be pointers to any scalar numeric
+// type, or one of
+//    string        (matched piece is copied to string)
+//    StringPiece   (StringPiece is mutated to point to matched piece)
+//    T             (where "bool T::ParseFrom(const char*, int)" exists)
+//    NULL          (the corresponding matched sub-pattern is not copied)
+//
+// CAVEAT: An optional sub-pattern that does not exist in the matched
+// string is assigned the empty string.  Therefore, the following will
+// return false (because the empty string is not a valid number):
+//    int number;
+//    pcrecpp::RE::FullMatch("abc", "[a-z]+(\\d+)?", &number);
+//
+// -----------------------------------------------------------------------
+// DO_MATCH
+//
+// The matching interface supports at most 16 arguments per call.
+// If you need more, consider using the more general interface
+// pcrecpp::RE::DoMatch().  See pcrecpp.h for the signature for DoMatch.
+//
+// -----------------------------------------------------------------------
+// PARTIAL MATCHES
+//
+// You can use the "PartialMatch" operation when you want the pattern
+// to match any substring of the text.
+//
+// Example: simple search for a string:
+//    pcrecpp::RE("ell").PartialMatch("hello");
+//
+// Example: find first number in a string:
+//    int number;
+//    pcrecpp::RE re("(\\d+)");
+//    re.PartialMatch("x*100 + 20", &number);
+//    assert(number == 100);
+//
+// -----------------------------------------------------------------------
+// UTF-8 AND THE MATCHING INTERFACE:
+//
+// By default, pattern and text are plain text, one byte per character.
+// The UTF8 flag, passed to the constructor, causes both pattern
+// and string to be treated as UTF-8 text, still a byte stream but
+// potentially multiple bytes per character. In practice, the text
+// is likelier to be UTF-8 than the pattern, but the match returned
+// may depend on the UTF8 flag, so always use it when matching
+// UTF8 text.  E.g., "." will match one byte normally but with UTF8
+// set may match up to three bytes of a multi-byte character.
+//
+// Example:
+//    pcrecpp::RE_Options options;
+//    options.set_utf8();
+//    pcrecpp::RE re(utf8_pattern, options);
+//    re.FullMatch(utf8_string);
+//
+// Example: using the convenience function UTF8():
+//    pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8());
+//    re.FullMatch(utf8_string);
+//
+// NOTE: The UTF8 option is ignored if pcre was not configured with the
+//       --enable-utf8 flag.
+//
+// -----------------------------------------------------------------------
+// PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE
+//
+// PCRE defines some modifiers to change the behavior of the regular
+// expression engine.
+// The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle
+// to pass such modifiers to a RE class.
+//
+// Currently, the following modifiers are supported
+//
+//    modifier              description               Perl corresponding
+//
+//    PCRE_CASELESS         case insensitive match    /i
+//    PCRE_MULTILINE        multiple lines match      /m
+//    PCRE_DOTALL           dot matches newlines      /s
+//    PCRE_DOLLAR_ENDONLY   $ matches only at end     N/A
+//    PCRE_EXTRA            strict escape parsing     N/A
+//    PCRE_EXTENDED         ignore whitespaces        /x
+//    PCRE_UTF8             handles UTF8 chars        built-in
+//    PCRE_UNGREEDY         reverses * and *?         N/A
+//    PCRE_NO_AUTO_CAPTURE  disables matching parens  N/A (*)
+//
+// (For a full account on how each modifier works, please check the
+// PCRE API reference manual).
+//
+// (*) Both Perl and PCRE allow non matching parentheses by means of the
+// "?:" modifier within the pattern itself. e.g. (?:ab|cd) does not
+// capture, while (ab|cd) does.
+//
+// For each modifier, there are two member functions whose name is made
+// out of the modifier in lowercase, without the "PCRE_" prefix. For
+// instance, PCRE_CASELESS is handled by
+//    bool caseless(),
+// which returns true if the modifier is set, and
+//    RE_Options & set_caseless(bool),
+// which sets or unsets the modifier.
+//
+// Moreover, PCRE_EXTRA_MATCH_LIMIT can be accessed through the
+// set_match_limit() and match_limit() member functions.
+// Setting match_limit to a non-zero value will limit the executation of
+// pcre to keep it from doing bad things like blowing the stack or taking
+// an eternity to return a result.  A value of 5000 is good enough to stop
+// stack blowup in a 2MB thread stack.  Setting match_limit to zero will
+// disable match limiting.  Alternately, you can set match_limit_recursion()
+// which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much pcre
+// recurses.  match_limit() caps the number of matches pcre does;
+// match_limit_recrusion() caps the depth of recursion.
+//
+// Normally, to pass one or more modifiers to a RE class, you declare
+// a RE_Options object, set the appropriate options, and pass this
+// object to a RE constructor. Example:
+//
+//    RE_options opt;
+//    opt.set_caseless(true);
+//
+//    if (RE("HELLO", opt).PartialMatch("hello world")) ...
+//
+// RE_options has two constructors. The default constructor takes no
+// arguments and creates a set of flags that are off by default.
+//
+// The optional parameter 'option_flags' is to facilitate transfer
+// of legacy code from C programs.  This lets you do
+//    RE(pattern, RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str);
+//
+// But new code is better off doing
+//    RE(pattern,
+//      RE_Options().set_caseless(true).set_multiline(true)).PartialMatch(str);
+// (See below)
+//
+// If you are going to pass one of the most used modifiers, there are some
+// convenience functions that return a RE_Options class with the
+// appropriate modifier already set:
+// CASELESS(), UTF8(), MULTILINE(), DOTALL(), EXTENDED()
+//
+// If you need to set several options at once, and you don't want to go
+// through the pains of declaring a RE_Options object and setting several
+// options, there is a parallel method that give you such ability on the
+// fly. You can concatenate several set_xxxxx member functions, since each
+// of them returns a reference to its class object.  e.g.: to pass
+// PCRE_CASELESS, PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one
+// statement, you may write
+//
+//    RE(" ^ xyz \\s+ .* blah$", RE_Options()
+//                            .set_caseless(true)
+//                            .set_extended(true)
+//                            .set_multiline(true)).PartialMatch(sometext);
+//
+// -----------------------------------------------------------------------
+// SCANNING TEXT INCREMENTALLY
+//
+// The "Consume" operation may be useful if you want to repeatedly
+// match regular expressions at the front of a string and skip over
+// them as they match.  This requires use of the "StringPiece" type,
+// which represents a sub-range of a real string.  Like RE, StringPiece
+// is defined in the pcrecpp namespace.
+//
+// Example: read lines of the form "var = value" from a string.
+//    string contents = ...;                 // Fill string somehow
+//    pcrecpp::StringPiece input(contents);  // Wrap in a StringPiece
+//
+//    string var;
+//    int value;
+//    pcrecpp::RE re("(\\w+) = (\\d+)\n");
+//    while (re.Consume(&input, &var, &value)) {
+//      ...;
+//    }
+//
+// Each successful call to "Consume" will set "var/value", and also
+// advance "input" so it points past the matched text.
+//
+// The "FindAndConsume" operation is similar to "Consume" but does not
+// anchor your match at the beginning of the string.  For example, you
+// could extract all words from a string by repeatedly calling
+//     pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word)
+//
+// -----------------------------------------------------------------------
+// PARSING HEX/OCTAL/C-RADIX NUMBERS
+//
+// By default, if you pass a pointer to a numeric value, the
+// corresponding text is interpreted as a base-10 number.  You can
+// instead wrap the pointer with a call to one of the operators Hex(),
+// Octal(), or CRadix() to interpret the text in another base.  The
+// CRadix operator interprets C-style "0" (base-8) and "0x" (base-16)
+// prefixes, but defaults to base-10.
+//
+// Example:
+//   int a, b, c, d;
+//   pcrecpp::RE re("(.*) (.*) (.*) (.*)");
+//   re.FullMatch("100 40 0100 0x40",
+//                pcrecpp::Octal(&a), pcrecpp::Hex(&b),
+//                pcrecpp::CRadix(&c), pcrecpp::CRadix(&d));
+// will leave 64 in a, b, c, and d.
+//
+// -----------------------------------------------------------------------
+// REPLACING PARTS OF STRINGS
+//
+// You can replace the first match of "pattern" in "str" with
+// "rewrite".  Within "rewrite", backslash-escaped digits (\1 to \9)
+// can be used to insert text matching corresponding parenthesized
+// group from the pattern.  \0 in "rewrite" refers to the entire
+// matching text.  E.g.,
+//
+//   string s = "yabba dabba doo";
+//   pcrecpp::RE("b+").Replace("d", &s);
+//
+// will leave "s" containing "yada dabba doo".  The result is true if
+// the pattern matches and a replacement occurs, or false otherwise.
+//
+// GlobalReplace() is like Replace(), except that it replaces all
+// occurrences of the pattern in the string with the rewrite.
+// Replacements are not subject to re-matching.  E.g.,
+//
+//   string s = "yabba dabba doo";

+*************************************************/
+
+/* This is a demonstration program to illustrate the most straightforward ways
+of calling the PCRE regular expression library from a C program. See the
+pcresample documentation for a short discussion ("man pcresample" if you have
+the PCRE man pages installed).
+
+In Unix-like environments, compile this program thuswise:
+
+  gcc -Wall pcredemo.c -I/usr/local/include -L/usr/local/lib \
+    -R/usr/local/lib -lpcre
+
+Replace "/usr/local/include" and "/usr/local/lib" with wherever the include and
+library files for PCRE are installed on your system. You don't need -I and -L
+if PCRE is installed in the standard system libraries. Only some operating
+systems (e.g. Solaris) use the -R option.
+
+Building under Windows:
+
+If you want to statically link this program against a non-dll .a file, you must
+define PCRE_STATIC before including pcre.h, otherwise the pcre_malloc() and
+pcre_free() exported functions will be declared __declspec(dllimport), with
+unwanted results. So in this environment, uncomment the following line. */

+* If the previous match WAS for an empty string, we can't do that, as it *
+* would lead to an infinite loop. Instead, a special call of pcre_exec() *
+* is made with the PCRE_NOTEMPTY_ATSTART and PCRE_ANCHORED flags set.    *
+* The first of these tells PCRE that an empty string at the start of the *
+* subject is not a valid match; other possibilities must be tried. The   *
+* second flag restricts PCRE to one match attempt at the initial string  *
+* position. If this match succeeds, an alternative to the empty string   *
+* match has been found, and we can proceed round the loop.               *

+  (INFO: this is regex-directed, NFA)
+  AH:  9-11-04 - pcre_free: removed var, pcre already gives the ptr, now
+			    everything works as it should (no more crashes)
+		 -> removed CheckRegExp because pcre handles errors perfectly
+      10-11-04 - added pcError (errorhandling), pcInit
+      13-11-04 - removed the ErrorPos = 0 check -> always print erroroffset
+      17-10-05 - support for \1-\9 backreferences in TpcRegExp.GetReplStr
+      17-02-06 - added RunTimeOptions: caller can set options while searching
+      19-02-06 - added SearchOfs(): let PCRE use the complete string and offset
+		 into the string itself
+      20-12-06 - support for version 7.0

+This is a file of miscellaneous text that is used as test data for checking
+that the pcregrep command is working correctly. The file must be more than 24K
+long so that it needs more than a single read() call to process it. New
+features should be added at the end, because some of the tests involve the
+output of line numbers, and we don't want these to change.
+
+PATTERN at the start of a line.
+In the middle of a line, PATTERN appears.
+
+This pattern is in lower case.
+
+Here follows a whole lot of stuff that makes the file over 24K long.
