23 # Script : gtkdoc-mktmpl
24 # Description : This creates or updates the template files which contain the
25 # manually-edited documentation. (A 'template' is a simple text
26 # form which is filled in with the description of a function,
27 # macro, enum, or struct. For functions and macros it also
28 # contains fields for describing the parameters.)
30 # This script reads in the existing templates, found in
31 # tmpl/*.sgml, moves these files to tmpl/*.sgml.bak, and then
32 # recreates the .sgml files according to the structure given in
33 # the file $MODULE-sections.txt.
35 # Any new templates added, or new function parameters, are
36 # marked with 'FIXME' so you can do a grep to see which parts
39 # Any templates which are no longer used (i.e. they are remove
40 # from $MODULE-sections.txt) are placed in the file
41 # tmpl/$MODULE-unused.sgml. If they are included again later
42 # they are automatically copied back into position.
43 # If you are certain that these templates will never be used
44 # again you can delete them from tmpl/$MODULE-unused.sgml.
46 # Any parameters to functions which are no longer used are
47 # separated from the rest of the parameters with the line
48 # '<!-- # Unused Parameters # -->'. It may be that the parameter
49 # name has just been changed, in which case you can copy the
50 # description to the parameter with the new name. You can delete
51 # the unused parameter descriptions when no longer needed.

822 # set a flag in the %DeclarationConditional hash so the

826 # gtk_object_ref, the function declaration takes precedence.

829 # _name name;' in which case the declaration may be empty.

831 # that overrides the empty declaration.
