2021-08-26qapi: make 'if' condition strings simple identifiersMarc-André Lureau
Change the 'if' condition strings to be C-agnostic. It will accept '[A-Z][A-Z0-9_]*' identifiers. This allows to express configuration conditions in other languages (Rust or Python for ex) or other more suitable forms.

2021-08-26qapi: Fix crash on redefinition with a different conditionMarkus Armbruster
QAPISchema._make_implicit_object_type() asserts that when an implicit object type is used multiple times, @ifcond is the same for all uses. It will be for legitimate uses, i.e. simple union branch wrapper types. A comment explains this. The assertion fails when a command or event is redefined with a different condition. The redefinition is an error, but it's flagged only later. Fixing the assertion would complicate matters further. Not worthwhile, drop it instead. We really need to get rid of simple unions. Tweak test case redefined-event to cover redefinition with a different condition.

2017-03-16qapi: Back out doc comments added just to please qapi.pyMarkus Armbruster
This reverts commit 3313b61's changes to tests/qapi-schema/, except for tests/qapi-schema/doc-*. We could keep some of these doc comments to serve as positive test cases. However, they don't actually add to what we get from doc comment use in actual schemas, as we we don't test output matches expectations, and don't systematically cover doc comment features. Proper positive test coverage would be nice.

2017-01-16qapi: add qapi2texi scriptMarc-André Lureau
As the name suggests, the qapi2texi script converts JSON QAPI description into a texi file suitable for different target formats (info/man/txt/pdf/html...). It parses the following kind of blocks: Free-form: ## # = Section # == Subsection # # Some text foo with *emphasis* # 1. with a list # 2. like that # # And some code: # | $ echo foo # | -> do this # | <- get that # ## Symbol description: ## # @symbol: # # Symbol body ditto ergo sum. Foo bar # baz ding. # # @param1: the frob to frobnicate # @param2: #optional how hard to frobnicate # # Returns: the frobnicated frob. # If frob isn't frobnicatable, GenericError. # # Since: version # Notes: notes, comments can have # - itemized list # - like this # # Example: # # -> { "execute": "quit" } # <- { "return": {} } # ## That's roughly following the following EBNF grammar: api_comment = "##\n" comment "##\n" comment = freeform_comment | symbol_comment freeform_comment = { "# " text "\n" | "#\n" } symbol_comment = "# @" name ":\n" { member | tag_section | freeform_comment } member = "# @" name ':' [ text ] "\n" freeform_comment tag_section = "# " ( "Returns:", "Since:", "Note:", "Notes:", "Example:", "Examples:" ) [ text ] "\n" freeform_comment text = free text with markup Note that the grammar is ambiguous: a line "# @foo:\n" can be parsed both as freeform_comment and as symbol_comment. The actual parser recognizes symbol_comment. See docs/qapi-code-gen.txt for more details. Deficiencies and limitations: - the generated QMP documentation includes internal types - union type support is lacking - type information is lacking in generated documentation - doc comment error message positions are imprecise, they point to the beginning of the comment. - a few minor issues, all marked TODO/FIXME in the code Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20170113144135.5150-16-marcandre.lureau@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> [test-qapi.py tweaked to avoid trailing empty lines in .out] Signed-off-by: Markus Armbruster <armbru@redhat.com>
2015-05-05qapi: Better error messages for duplicated expressionsEric Blake
The previous commit demonstrated that the generator overlooked duplicate expressions: - a complex type or command reusing a built-in type name - redeclaration of a type name, whether by the same or different metatype - redeclaration of a command or event - collision of a type with implicit 'Kind' enum for a union - collision with an implicit MAX enum constant Since the c_type() function in the generator treats all names as being in the same namespace, this patch adds a global array to track all known names and their source, to prevent collisions before it can cause further problems. While valid .json files won't trigger any of these cases, we might as well be nicer to developers that make a typo while trying to add new QAPI code.

2015-05-05qapi: Add tests of redefined expressionsEric Blake
Demonstrate that the qapi generator doesn't deal very well with redefined expressions. At the parse level, they are silently accepted; and while the testsuite just stops at parsing, I've further tested that many of them cause generator crashes or invalid C code if they were appended to qapi-schema-test.json. A later patch will tighten things up and adjust the testsuite to match.
