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 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?

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.

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.
