Hi Matthew,

as this is something I wanted to do myself, I really like it! I've
been looking at the code only so far; I'll test it once I have access
to my computer in the evening. A few comments:

1. In tm_tag.c it would be better to have ctagKinds languageKinds[]
separate for each language and then have allKinds array indexed by
lang_id containing languageKinds[] of all languages. So to get to
language's tags, you would just do allKinds[lang_id] instead of going
through the whole list every time. (a dummy entry would be used for
lang_id's not present in the table)

2. You can get function parameters from extension fields when you run
ctags with --fields=+S (and I believe you get variable type with "t").
Check the man pages of ctags. I think this is safer than using your

3. More general comment - if we have ctags file parsing support, it's
a question whether Geany should continue using the old format and its
generation. Tags generation would be then redundant in Geany if you
can do the same with ctags (and ctags is the right tool to generate
tags, not a text editor). Geany's documentation would then just say
what flags should be used for ctags in order to create all the
necessary fields.
