grep options

grep options

[Ken Goldman]

When I use grep on C source, I'd like it to search all C source (.c, .h, 
.cpp), not just the files with the same extension.

I could do that with the (obsolete) igrep like this.  Can I reproduce it 
with emacs 23 / grep?

(put 'igrep-files-default 'c-mode
      (lambda () "*.[ch] *.cpp"))

Anything grep that come with anything-config.el allow you to do that in
two ways:

1) If you want to do a recursive search from your directory, access grep
with C-u, you will be prompted with "OnlyExt: ", add all the ext you
want like:
*.c *.h *.cpp
(separated with space)

2) if you don't want to recurse, from anything-find-files, narrow dow
the list in your directory by adding a space followed by c$\|h$\|cpp$ at
end of prompt e.g
Pattern: /home/you/work/ c$\|h$\|cpp$

then select grep (no prefix arg this time) and start writting your
pattern.

FYI, this grep is incremental, results changes as you write in minibuffer.

NOTE: You DON'T need the file anything-grep.el that is in anything repo,
this work out of the box with the files:

anything.el
anything-config.el
anything-match-plugin.el

Here is the anything repo:
http://repo.or.cz/w/anything-config.git

Sorry forget to mention you have to mark all with M-m before grepping.

This looks like a lot more work than igrep.  I didn't have to select files 
and manually
enter the extensions.  igrep just knew that, if the file was c-mode, it 
should search
*.[ch] *.cpp --- by default.

In combination for "search for the string under point", I could grep with 
a single keystroke.

Try M-x lgrep instead.  It also comes preconfigured via grep-files-aliases, but
you should be able to push ("ALIAS" . "WILDCARD ...") entries on to the front to
customize it.

lgrep is OK, but it requires 3 <enter>'s to get anything done.  grep
requires just one <enter>.

	- confirm the search string
	- confirm the file names
	- confirm the directory

Is there a way to tell lgrep to skip the latter two questions?

C-u C-u lgrep
from the doc string:

With C-u prefix, you can edit the constructed shell command line
before it is executed.
With two C-u prefixes, directly edit and run `grep-command'.

That sounds like an awful ui. Do you mind submitting a bug report by M-x
report-emacs-bug so that it may be fixed upstream? thanks.

I don't like that UI either, but I can't understand what you consider as
a bug: that UI is lgrep's raison d'être.
If you don't like it, you can use (C-u?) M-x grep.

I hesitate to file a bug report because I assume it's not a bug, just me 
missing an option or some customization.

So does anyone know how to make lgrep default to the files in 
grep-files-aliases and default to the current directory without prompting?

grep seems even worse than lgrep.  At least lgrep fills in the word 
under the point as the search string.

I'm looking for an equivalent to the old igrep - default to the word 
under the point, the files with the same mode, and the current directory 
--- with no prompting.

Hi Ken,

Good to hear from you again!

Perhaps you can do something like this:

(require 'igrep)

(defadvice lgrep (before interactive-igrep first activate)
   "Read REGEXP, FILES, and DIR using `igrep-read-args'."
   (interactive
    (progn
      (grep-compute-defaults)
      (let ((igrep-args (igrep-read-args)))
        ;; convert (PROGRAM REGEX FILES OPTIONS) to (REGEXP FILES DIR CONFIRM):
        (list (nth 1 igrep-args)
	     (mapconcat 'file-name-nondirectory (nth 2 igrep-args) " ")
	     (mapconcat 'file-name-directory (nth 2 igrep-args) " ")
	     nil)))))

Not if you provide the C-u prefix.
