Mor ethan one modulefile may be +# specified. (required) +# -L --libgobject Specifies the name of the gobject library (optional but +# must be specified if "libgobject-2.0.so" is not availble) +# -s --separate Create separate files for objects and function/method defs +# using the given name as the base name (optional). If this +# is not specified the combined object and function defs +# will be output to sys.stdout. +# -f --defsfile Extract defs from the given file to filter the output defs +# that is don't output defs that are defined in the +# defsfile. More than one deffile may be specified. +# -D --defines Include portions of the defsfile defs that are conditional +# on the given define, for example GDK_TARGET_X11. Only +# useful with the --defsfile option +# -m --modulename The prefix to be stripped from the front of function names +# for the given module +# -p --useprefix Use the modulename prefix as a hint to split names into +# module and name for object and enum defs. Also used for +# generating type codes. +# --onlyenums Only produce defs for enums and flags +# --onlyobjdefs Only produce defs for objects +# --onlyvirtuals Only produce defs for virtuals +# --genpropgetsets Experimental option to generate prop-getset annotations. +# Not supported by codegen.py and friends. +# +# Examples: +# +# python defsgen.py -m pango -l libpango-1.0.so \ +# /usr/local/include/pango-1.0/pango/*.h >/tmp/pango.defs +# +# - Outputs all defs for the pango module.using the library module +# libpango-1.0.so. +# +# python defsgen.py -m gdk -DGDK_TARGET_X11 -l libgdk-x11-2.0.so \ +# -l libgdk_pixbuf-2.0.so -s /tmp/gdk-2.10 \ +# -f /usr/tmp/pygtk/gtk/gdk-base.defs \ +# /usr/local/include/gtk-2.0/gdk/*.h \ +# /usr/local/include/gtk-2.0/gdk-pixbuf/*.h +# +# - Outputs the gdk module defs that are not contained in the defs file +# /usr/tmp/pygtk/gtk/gdk-base.defs.
