6 Glib::ParseXSDoc - Parse POD and XSub declarations from XS files.
7
9 This is the heart of an automatic API reference documentation system
10 for XS-based Perl modules. FIXME more info here!!
11 FIXME document recognized POD directives and the output data structures
13
15 xsdocparse (@filenames)
16 Parse xs files for xsub signatures and pod. Writes to standard
17 output a data structure suitable for eval'ing in another Perl
18 script, describing all the stuff found. The output contains three
19 variables:
20 $xspods = ARRAYREF
22 array of pods found in the verbatim C portion of the XS file,
23 listed in the order found. These are assumed to pertain to the
24 XS/C api, not the Perl api. Any "=for apidoc" paragraphs
25 following an "=object" paragraphs in the verbatim sections are
26 stripped (as are the "=object" paragraphs), and will appear
27 instead in "$data->{$package}{pods}".
28 $data = HASHREF
30 big hash keyed by package name (as found in the MODULE line),
31 containing under each key a hash with all the xsubs and pods in
32 that package, in the order found. Packages are consolidated
33 across multiple files.
34 FYI, this creates a new parser and calls "parse_file" on it for
36 each input filename; then calls "swizzle_pods" to ensure that any
37 "=for apidoc name" pods are matched up with their target xsubs; and
38 finally calls Data::Dumper to write the data to stdout. So, if you
39 want to get finer control over how the output is created, or keep
40 all the data in-process, now you know how. :-)
41
43 $Glib::ParseXSDoc::verbose
44 If true, this causes the parser to be verbose.
45 $parser = Glib::ParseXSDoc->new
47 Create a new xsub parser.
48 string = $parser->package
50 Get the current package name. Falls back to the module name. Will
51 be undef if the parser hasn't reached the first MODULE line.
52 HASHREF = $parser->pkgdata
54 The data hash corresponding to the current package, honoring the
55 most recently encountered "=for object" directive. Ensures that it
56 exists. Returns a reference to the member of the main data
57 structure, so modifications are permanent and useful.
58 $parser->parse_file (filename)
60 Parse one xs file. Stores all the collected data in $parser's
61 internal data structures.
62 $parser->swizzle_pods
64 Match "=for apidoc" pods to xsubs.
65 $parser->preprocess_pods
67 Honor the "__hide__" and "__function__" directives in "=for apidoc"
68 lines.
69 We look for the strings anywhere, but you'll typically have it at
71 the end of the line, e.g.:
72 =for apidoc symname __hide__ for detached blocks
74 =for apidoc __hide__ for attached blocks
75 =for apidoc symname __function__ for functions rather than methods
77 =for apidoc __function__ for functions rather than methods
78 bool = $parser->is_module_line ($line)
80 Analyze $line to see if it contains an XS MODULE directive. If so,
81 returns true after setting the $parser's module, package, and
82 prefix accordingly.
83 $pod = $parser->slurp_pod_paragraph ($firstline,
85 $term_regex=/^=cut\s*/)
86 Slurp up POD lines from $filehandle from here to the next
87 $term_regex or EOF. Since you probably already read a line to
88 determine that we needed to start a pod, you can pass that first
89 line to be included.
90 $xsub = $parser->parse_xsub (\@lines)
92 $xsub = $parser->parse_xsub (@lines)
93 Parse an xsub header, in the form of a list of lines, into a data
94 structure describing the xsub. That includes pulling out the
95 argument types, aliases, and code type.
96 Without artificial intelligence, we cannot reliably determine
98 anything about the types or number of parameters returned from
99 xsubs with PPCODE bodies.
100 OUTLIST parameters are pulled from the args list and put into an
102 "outlist" key. IN_OUTLIST parameters are put into both.
103 Data type names are not mangled at all.
105 Note that the method can take either a list of lines or a reference
107 to a list of lines. The flat list form is provided for
108 compatibility; the reference form is preferred, to avoid
109 duplicating a potentially large list of strings.
110 $parser->clean_out_empty_pods
112 Looks through the data member of the parser and removes any keys
113 (and associated values) when no pod, enums, and xsubs exist for the
114 package.
