Parsing tags (gnatxref)

Parsing tags (gnatxref)

[Preben Randhol]

For vim and other utilities there are tools for using tags that are
generated from exhuberant ctags. (http://ctags.sf.net) However ctags
doesn't support Ada, but with gnat there is gnatxref.

gnatxref has a switch for generating Vi compatible tag lists, but it
gives a too minimalistic list. I mean that it doesn't include
information on what the different tags is like procedure, function,
object etc... So I'm looking into making a program for parsing the
full tag file that gnatxref can generate. However before I start doing
this I would like to know if somebody else have already done this?

Thanks in advance.

If "standard" vi (or Vim) can use this information, then "standard"
gnatxref should output it; send in a request to report@gnat.com. Since
they already generate the info, it should not be hard to add to the
"vi" output.

Better yet, get the sources, do the mod yourself, and send that in :).

There is code in Emacs ada-mode to deal with gnatxref; I'm not sure
exactly how it works. But I guess you meant "has anybody already done
this for vim".

Depends what you mean by standard :-) Vim is far more powerful and
better than Vi. I guess that one would perhaps need an extra flag.

The format can be found here: http://ctags.sourceforge.net/FORMAT

I think I'll first make a solution to use gnatxref as-is because then I
get to experiment with what works best. Then I'll see if gnatxref can be
improved. Is it written in Ada?

No not really, but I don't know lisp so I think I would be a bit lost
there. :-)
