# wikilinks.py:
# This throwaway program can be used to convert idl_chapter_refs.txt to a
# "fake" IDL file that can be fed to doxygen to get the DevGuide Wiki links.
#
# Usage:
#
# In core, generate a file letting us know what kinds of entities to declare:
# cat <(make -s cmd cmd='$(INSTDIR)/sdk/bin/unoidl-read --summary $(INSTDIR)/program/types.rdb') <(make -s cmd cmd='$(INSTDIR)/sdk/bin/unoidl-read --summary $(INSTDIR)/program/types.rdb $(INSTDIR)/program/types/offapi.rdb') | LC_ALL=C sort | LC_ALL=C uniq > /tmp/kinds
#
# Run the script while feeding it the chapter references and output the fake IDL:
# python wikilinks.py < idl_chapter_refs.txt > generated_idl_chapter_refs.idl
