Hi,

Semantic stores everything, so it will keep both.  If you use the low 
level search commands, it will also identify both if you do a search by 
name, unless you specifically ask for a "find the first by name".

If you instead refer to commands such as smart completion, those 
commands will call semantic-analyze-select-best-tag, which in turn 
returns only one item.

I recently added the semantic-ia-show-variants command to CEDET/CVS 
which will show all occurrences.

Does that help?

What are these low level search commands? Are they by default bound to 
any keys by semantic? Are you referring to senator-nonincremental-* 
search commands? I tried those but they only seem to find tags within 
the current file.

Sorry, I should have specified "low level search functions", as they are 
not commands.

The functions in question are:

semanticdb-find-tags-by-name
semanticdb-find-tags-by-name-regexp

The non-db version will search only the local file.

Thanks for clarifying that. I was trying to write a simple command with 
this, but I have a feeling I am over simplifying.

This is my attempt,

(defun foo(name)
   (interactive "s Tag:")
   (print (semanticdb-find-tags-by-name name nil t)))

Of course this is extremely crude, but for the future I wanted to get a 
prompt of the various function definitions maybe in a separate *Help 
like* buffer.

Can you point me in the right direction?

Appreciate you working on CEDET. It has simplified my life immensely. :)

Hi Suvayu,

   I've lost track of what your original question was.  There is a 
command in the CVS version of CEDET which I added recently called 
semantic-ia-show-variants.  It looks up the symbol under point, and 
shows different variants of that symbol if there are multiple things of 
the same name.  You could look at it's code, since that function is 
designed as a learning example.

   Alternately, you can use a debugging routine as an example of what to 
do.  The function semantic-adebug-searchdb shows how to do a search, and 
then show the search in an interactive dump buffer.

   You can use

M-x find-function RET

to go to a function by name, or you can use

C-h f some-symbol RET

and then click on the file where the symbol is located to go there.

Does this help?

Eric

This helps a ton! Thanks Eric. I will look at the source for those and 
try to write something. If it is any good and worth sharing, I'll post 
it here. ;)
