Function Documentation

emit_documentation()

static void emit_documentation ( const char * in_fname )

static

Read the documentation file with name IN_FNAME, perform substitutions
to incorporate information from hook_array, and emit the result on stdout.
Hooks defined with DEFHOOK / DEFHOOKPOD are emitted at the place of a
matching @hook in the input file; if there is no matching @hook, the
hook is emitted after the hook that precedes it in target.def .
Usually, the emitted hook documentation starts with the hook
signature, followed by the string from the doc field.
The documentation is bracketed in @deftypefn / @deftypevr and a matching
@end.
While emitting the doc field, an @findex entry is added
to the affected paragraph.
If the doc field starts with '*', the leading '*' is stripped, and the doc
field is otherwise emitted unaltered; no function signature/
@deftypefn/deftypevr/@end is emitted.
In particular, a doc field of "*" means not to emit any ocumentation for
this target.def / hook_array entry at all (there might be documentation
for this hook in the file named IN_FNAME, though).
A doc field of 0 is used to append the hook signature after the previous
hook's signture, so that one description can be used for a group of hooks.
When the doc field is "", @deftypefn/@deftypevr and the hook signature
is emitted, but not the matching @end.  This allows all the free-form
documentation to be placed in IN_FNAME, to work around GPL/GFDL
licensing incompatibility issues.

emit_init_macros()

static void emit_init_macros ( const char * docname )

static

Emit #defines to stdout (this will be redirected to generate
target-hook-def.h) which set target hooks initializer macros
to their default values.  These should only be emitted for hooks
whose type is given by DOCNAME.
