See the -sections below for further details on formatting and configuration options. - -To dump a variable with full newlines, indentation, type, and pointer -information use Dump, Fdump, or Sdump: - spew.Dump(myVar1, myVar2, ...) - spew.Fdump(someWriter, myVar1, myVar2, ...) - str := spew.Sdump(myVar1, myVar2, ...) - -Alternatively, if you would prefer to use format strings with a compacted inline -printing style, use the convenience wrappers Printf, Fprintf, etc with -%v (most compact), %+v (adds pointer addresses), %#v (adds types), or -%#+v (adds types and pointer addresses): - spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - -Configuration Options - -Configuration of spew is handled by fields in the ConfigState type. For -convenience, all of the top-level functions use a global state available -via the spew.Config global. - -It is also possible to create a ConfigState instance that provides methods -equivalent to the top-level functions. This allows concurrent configuration -options. See the ConfigState documentation for more details. - -The following configuration options are available: - * Indent - String to use for each indentation level for Dump functions. - It is a single space by default. A popular alternative is "\t". - - * MaxDepth - Maximum number of levels to descend into nested data structures. - There is no limit by default. - - * DisableMethods - Disables invocation of error and Stringer interface methods. - Method invocation is enabled by default. - - * DisablePointerMethods - Disables invocation of error and Stringer interface methods on types - which only accept pointer receivers from non-pointer variables. - Pointer method invocation is enabled by default. - - * DisablePointerAddresses - DisablePointerAddresses specifies whether to disable the printing of - pointer addresses. This is useful when diffing data structures in tests. - - * DisableCapacities - DisableCapacities specifies whether to disable the printing of - capacities for arrays, slices, maps and channels. This is useful when - diffing data structures in tests. - - * ContinueOnMethod - Enables recursion into types after invoking error and Stringer interface - methods. Recursion after method invocation is disabled by default. - - * SortKeys - Specifies map keys should be sorted before being printed. Use - this to have a more deterministic, diffable output. Note that - only native types (bool, int, uint, floats, uintptr and string) - and types which implement error or Stringer interfaces are - supported with other types sorted according to the - reflect.Value.String() output which guarantees display - stability. Natural map order is used by default. - - * SpewKeys - Specifies that, as a last resort attempt, map keys should be - spewed to strings and sorted by those strings. This is only - considered if SortKeys is true. - -Dump Usage - -Simply call spew.Dump with a list of variables you want to dump: - - spew.Dump(myVar1, myVar2, ...) - -You may also call spew.Fdump if you would prefer to output to an arbitrary -io.Writer. For example, to dump to standard error: - - spew.Fdump(os.Stderr, myVar1, myVar2, ...) - -A third option is to call spew.Sdump to get the formatted output as a string: - - str := spew.Sdump(myVar1, myVar2, ...) - -Sample Dump Output - -See the Dump example for details on the setup of the types and variables being -shown here. - - (main.Foo) { - unexportedField: (*main.Bar)(0xf84002e210)({ - flag: (main.Flag) flagTwo, - data: (uintptr) <nil> - }), - ExportedField: (map[interface {}]interface {}) (len=1) { - (string) (len=3) "one": (bool) true - } - } - -Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C -command as shown. - ([]uint8) (len=32 cap=32) { - 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... | - 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0| - 00000020 31 32 |12| - } - -Custom Formatter - -Spew provides a custom formatter that implements the fmt.Formatter interface -so that it integrates cleanly with standard fmt package printing functions.

A single -// option may have both a short and a long name. Each option may be a flag or a -// value. A value takes an argument. -// -// Declaring no long names causes this package to process arguments like the -// traditional BSD getopt. -// -// Short flags may be combined into a single parameter. For example, "-a -b -c" -// may also be expressed "-abc". Long flags must stand on their own "--alpha -// --beta" -// -// Values require an argument. For short options the argument may either be -// immediately following the short name or as the next argument. Only one short -// value may be combined with short flags in a single argument; the short value -// must be after all short flags. For example, if f is a flag and v is a value, -// then: -// -// -vvalue (sets v to "value") -// -v value (sets v to "value") -// -fvvalue (sets f, and sets v to "value") -// -fv value (sets f, and sets v to "value") -// -vf value (set v to "f" and value is the first parameter) -// -// For the long value option val: -// -// --val value (sets val to "value") -// --val=value (sets val to "value") -// --valvalue (invalid option "valvalue") -// -// Values with an optional value only set the value if the value is part of the -// same argument. In any event, the option count is increased and the option is -// marked as seen. -// -// -v -f (sets v and f as being seen) -// -vvalue -f (sets v to "value" and sets f) -// --val -f (sets v and f as being seen) -// --val=value -f (sets v to "value" and sets f) -// -// There is no convenience function defined for making the value optional. The -// SetOptional method must be called on the actual Option. -// -// v := String("val", 'v', "", "the optional v") -// Lookup("v").SetOptional() -// -// var s string -// FlagLong(&s, "val", 'v', "the optional v).SetOptional() -// -// Parsing continues until the first non-option or "--" is encountered. -// -// The short name "-" can be used, but it either is specified as "-" or as part -// of a group of options, for example "-f-". If there are no long options -// specified then "--f" could also be used. If "-" is not declared as an option -// then the single "-" will also terminate the option processing but unlike -// "--", the "-" will be part of the remaining arguments. -// -// ADVANCED USAGE -// -// Normally the parsing is performed by calling the Parse function. If it is -// important to see the order of the options then the Getopt function should be -// used. The standard Parse function does the equivalent of: -// -// func Parse() { -// if err := getopt.Getopt(os.Args, nil); err != nil { -// fmt.Fprintln(os.Stderr, err) -// s.usage() -// os.Exit(1) -// } -// -// When calling Getopt it is the responsibility of the caller to print any -// errors. -// -// Normally the default option set, CommandLine, is used. Other option sets may -// be created with New. -// -// After parsing, the sets Args will contain the non-option arguments. If an -// error is encountered then Args will begin with argument that caused the -// error. -// -// It is valid to call a set's Parse a second time to amen flags or values. As -// an example: -// -// var a = getopt.Bool('a', "", "The a flag") -// var b = getopt.Bool('b', "", "The a flag") -// var cmd = "" -// -// var opts = getopt.CommandLine -// -// opts.Parse(os.Args) -// if opts.NArgs() > 0 { -// cmd = opts.Arg(0) -// opts.Parse(opts.Args()) -// } -// -// If called with set to { "prog", "-a", "cmd", "-b", "arg" } then both and and -// b would be set, cmd would be set to "cmd", and opts.Args() would return { -// "arg" }. -// -// Unless an option type explicitly prohibits it, an option may appear more than -// once in the arguments. The last value provided to the option is the value. -// -// MANDATORY OPTIONS -// -// An option marked as mandatory and not seen when parsing will cause an error -// to be reported such as: "program: --name is a mandatory option". An option -// is marked mandatory by using the Mandatory method: -// -// getopt.FlagLong(&fileName, "path", 0, "the path").Mandatory() -// -// Mandatory options have (required) appended to their help message: -// -// --path=value the path (required) -// -// MUTUALLY EXCLUSIVE OPTIONS -// -// Options can be marked as part of a mutually exclusive group. When two or -// more options in a mutually exclusive group are both seen while parsing then -// an error such as "program: options -a and -b are mutually exclusive" will be -// reported. Mutually exclusive groups are declared using the SetGroup method: -// -// getopt.Flag(&a, 'a', "use method A").SetGroup("method") -// getopt.Flag(&a, 'b', "use method B").SetGroup("method") -// -// A set can have multiple mutually exclusive groups. Mutually exclusive groups -// are identified with their group name in {}'s appeneded to their help message: -// -// -a use method A {method} -// -b use method B {method} -// -// BUILTIN TYPES -// -// The Flag and FlagLong functions support most standard Go types. For the -// list, see the description of FlagLong below for a list of supported types. -// -// There are also helper routines to allow single line flag declarations. These -// types are: Bool, Counter, Duration, Enum, Int16, Int32, Int64, Int, List, -// Signed, String, Uint16, Uint32, Uint64, Uint, and Unsigned. -// -// Each comes in a short and long flavor, e.g., Bool and BoolLong and include -// functions to set the flags on the standard command line or for a specific Set -// of flags. -// -// Except for the Counter, Enum, Signed and Unsigned types, all of these types -// can be declared using Flag and FlagLong by passing in a pointer to the -// appropriate type. -// -// DECLARING NEW FLAG TYPES -// -// A pointer to any type that implements the Value interface may be passed to -// Flag or FlagLong. -// -// VALUEHELP -// -// All non-flag options are created with a "valuehelp" as the last parameter. -// Valuehelp should be 0, 1, or 2 strings. The first string, if provided, is -// the usage message for the option. If the second string, if provided, is the -// name to use for the value when displaying the usage.
