'find use of' a symbol

'find use of' a symbol

[Rodrigo Canellas]

Hi,

Is there a 'find use of' function like in Emacs? I mean, a function that 
finds all the places where a certain symbol is used, given a group of files?
 
I read I can use 'grep', but I wonder if there is another way.


Thanks!

I have never heard of such a command, but I'd recommand for this use
case to use emacs built-in M-x grep command, because it will allow to
visit places interactively. This is very efficient.

If you have the "ID Utilities" installed, you can use "gid".
There are also interfaces to use cscope, eclipse and a bunch of other tools.

do you want to find all locations where the symbol appears, or where
the symbol is called, or including where it is defined?

i suppose you just want all locations where it appears. Besides “Alt+x
grep”, which i use, a better solution is probably tags. Unfortunately
you'll have to set it up first. See emacs manual on Tags. (info
"(emacs)Tags")

i know there are few other solutions but i've never tried... some show
all functions in a panel ... like modern IDE...

Tags only finds the location where a symbol is defined.  To find ALL
locations, ID Utils + the gid command is the way to go.

You can try  M-x lgrep  and  M-x rgrep  (recursive grep).
The interface is a bit more friendly than the barbone M-x grep.
