Thread: [Amforth] Ref Card Generation -- working hack

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

So here is a working hack to make a refcard with both the avr8/works and
common/words directory. Since I don't even sort of speak Perl I'll leave
any real fixes to someone who does. However, I made a few notes pointing
out the things that were the issue before.
There is still the issue of files that don't have the 3 lines at the top of
stack effects, category and description. It is easy to see which files need
to be fixed so they can be scanned correctly. The ones in the unclassified
group at the end can be a little tougher to find. I had to search for <.db
"-1"> to find that one in num-constants.asm. Those did fail pretty
gracefully though.

tl;dnr
This works in a hackish sort of way. Still work to do but closer now.
