Simple EMACS Grep

Anyone has a good EMACS Grep define to search only certain file types,
such as "*.c, *.h, *.s, *.cpp" and etc?

The standard EMACS "grep-find" search all file types.

Thanks,

I always use M-x grep for such cases. E.g.

M-x grep
Run grep (like this): grep -nH -e 'foo' *.c

I've never used grep-find so I'm not sure if there are any differences
between these two searches.

You need to add:

	\( -name "*.[chs]" -or -name "*.cpp“ \)

And so one if you have more detailed wishes.

Thanks, Peter.    Do you know where I can find the original "find-
grep" to customize?  Sorry I am still at a newbee level for EMACS and
has only binary version of 21.3 EMACS installed.

Have a look at M-x find-function grep-find once, and see that it first
checks the value of `grep-find-command', and then uses it's own unique
`grep-find-history' variable for the command history.

You could create a ".dired" file for the top-level directory of you C
project with:

  Local Variables:
  grep-find-command: "find . -type f \( -name '*.[hcs]' -or -name '*.cpp' \) -print0 | xargs -0 -e grep -n -e "
  End:

That should make it do what you want by default whenever you run it from
that location, provided you have first requested a directory listing via
dired so that the .dired is seen.

You could also, if you liked, use `add-to-list' to push that string onto
the `grep-find-history' in ~/.emacs.
