Glib::ParseXSDoc - Parse POD and XSub declarations from XS files.
This is the heart of an automatic API reference documentation system for XS-based Perl modules. FIXME more info here!!
FIXME document recognized POD directives and the output data structures
Parse xs files for xsub signatures and pod. Writes to standard output a data structure suitable for eval'ing in another Perl script, describing all the stuff found. The output contains three variables:
array of pods found in the verbatim C portion of the XS file,
listed in the order found.
These are assumed to pertain to the XS/C api,
not the Perl api.
=for apidoc paragraphs following an
=object paragraphs in the verbatim sections are stripped (as are the
and will appear instead in
big hash keyed by package name (as found in the MODULE line), containing under each key a hash with all the xsubs and pods in that package, in the order found. Packages are consolidated across multiple files.
this creates a new parser and calls
parse_file on it for each input filename; then calls
swizzle_pods to ensure that any
=for apidoc name pods are matched up with their target xsubs; and finally calls Data::Dumper to write the data to stdout.
if you want to get finer control over how the output is created,
or keep all the data in-process,
now you know how.
If true, this causes the parser to be verbose.
Create a new xsub parser.
Get the current package name. Falls back to the module name. Will be undef if the parser hasn't reached the first MODULE line.
The data hash corresponding to the current package,
honoring the most recently encountered
=for object directive.
Ensures that it exists.
Returns a reference to the member of the main data structure,
so modifications are permanent and useful.
Parse one xs file. Stores all the collected data in $parser's internal data structures.
=for apidoc pods to xsubs.
__function__ directives in
=for apidoc lines.
We look for the strings anywhere, but you'll typically have it at the end of the line, e.g.:
=for apidoc symname __hide__ for detached blocks =for apidoc __hide__ for attached blocks =for apidoc symname __function__ for functions rather than methods =for apidoc __function__ for functions rather than methods
Analyze $line to see if it contains an XS MODULE directive. If so, returns true after setting the $parser's module, package, and prefix accordingly.
Slurp up POD lines from $filehandle from here to the next $term_regex or EOF. Since you probably already read a line to determine that we needed to start a pod, you can pass that first line to be included.
Parse an xsub header, in the form of a list of lines, into a data structure describing the xsub. That includes pulling out the argument types, aliases, and code type.
Without artificial intelligence, we cannot reliably determine anything about the types or number of parameters returned from xsubs with PPCODE bodies.
OUTLIST parameters are pulled from the args list and put into an "outlist" key. IN_OUTLIST parameters are put into both.
Data type names are not mangled at all.
Looks through the data member of the parser and removes any keys (and associated values) when no pod, enums, and xsubs exist for the package.
