Extending etags.el + exuberant ctags for duplicate tag definitions

Extending etags.el + exuberant ctags for duplicate tag definitions

[Nordlöw]

Hi!

I am looking for a way to extend the behaviour of find-tag and similar
functions (in etags.el) together with exuberant ctags (either using
format 1 ("tags") or 2 ("TAGS")) to propose the following completions
for a tag say TAG that have multiple definitions say in the files fa.c
and fb.c in the following way:

Completions for TAG:

TAG@fa.c,
TAG@fb.c

or

TAG@foo()@fa.c,
TAG@bar()@fa.c

Is this possible using the file formats 1 or 2 that Exuberant Ctags
can produce?

Thanks in advance,
Nordlöw

It won't do tag-completion, but for browsing through tags with multiple
definitions, try:

Sorry for the late posting, but maybe this will still help. 

You can browse all tags (including duplicates) of all tags tables, complete
against them, and visit their source definitions, using Icicles
multi-command `icicle-search-tag'. Your minibuffer input filters the source
files to search, as well as the set of matching tags. Matching can use
regexps.

`icicle-search-tag' thus combines the functionality of standard commands
‘find-tag’ (`M-.’) to find a tag, ‘tags-loop-continue’ (`M-,’) to find
another matching tag, ‘tags-apropos’ to list all tags that match a regexp,
and ‘list-tags’ to show all tags (definitions) in a given source file.
