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>
