grep excludes

grep excludes

[Rustom Mody]

When we run grep the exclude list is this:

grep  --exclude=.\#\* --exclude=\*.o --exclude=\*\~ --exclude=\*.bin
--exclude=\*.lbin --exclude=\*.so --exclude=\*.a --exclude=\*.ln
--exclude=\*.blg --exclude=\*.bbl --exclude=\*.elc --exclude=\*.lof
--exclude=\*.glo --exclude=\*.idx --exclude=\*.lot --exclude=\*.fmt
--exclude=\*.tfm --exclude=\*.class --exclude=\*.fas --exclude=\*.lib
--exclude=\*.mem --exclude=\*.x86f --exclude=\*.sparcf --exclude=\*.dfsl
--exclude=\*.pfsl --exclude=\*.d64fsl --exclude=\*.p64fsl
--exclude=\*.lx64fsl --exclude=\*.lx32fsl --exclude=\*.dx64fsl
--exclude=\*.dx32fsl --exclude=\*.fx64fsl --exclude=\*.fx32fsl
--exclude=\*.sx64fsl --exclude=\*.sx32fsl --exclude=\*.wx64fsl
--exclude=\*.wx32fsl --exclude=\*.fasl --exclude=\*.ufsl --exclude=\*.fsl
--exclude=\*.dxl --exclude=\*.lo --exclude=\*.la --exclude=\*.gmo

--exclude=\*.pgs --exclude=\*.tps --exclude=\*.vrs --exclude=\*.pyc
--exclude=\*.pyo -i --color -nH -e emacs * .*




---------------------
It literally fills up and overflows the whole window!!

Given that most of these are file types of OSes/Apps that are long defunct
Yeah I know about
1. option grep-find-ignored-files
2. That GREP_OPTIONS env variable became deprecated

But grep has an --exclude-from option that will take all these globs from a
file

Would it not be nice to have a customize option that reads this file (if
non-nil)
rather than filling a screen-full of irrelevant excludes??

Rather than excluding the whole computer one
typically use the input file list to limit the
search space...

Just to be clear this is the default behavior of lgrep [sorry should have been 
clear when I said 'grep']

ie emacs started -Q
M-x lgrep
Giving all its 3 options
 1. Search for
 2. In files
 3. In directory 

This is its output

For rgrep its bigger:


find . -type d \( -path \*/SCCS -o -path \*/RCS -o -path \*/CVS -o -path \*/MCVS -o -path \*/.svn -o -path \*/.git -o -path \*/.hg -o -path \*/.bzr -o -path \*/_MTN -o -path \*/_darcs -o -path \*/\{arch\} \) -prune -o \! -type d \( -name .\#\* -o -name \*.o -o -name \*\~ -o -name \*.bin -o -name \*.lbin -o -name \*.so -o -name \*.a -o -name \*.ln -o -name \*.blg -o -name \*.bbl -o -name \*.elc -o -name \*.lof -o -name \*.glo -o -name \*.idx -o -name \*.lot -o -name \*.fmt -o -name \*.tfm -o -name \*.class -o -name \*.fas -o -name \*.lib -o -name \*.mem -o -name \*.x86f -o -name \*.sparcf -o -name \*.dfsl -o -name \*.pfsl -o -name \*.d64fsl -o -name \*.p64fsl -o -name \*.lx64fsl -o -name \*.lx32fsl -o -name \*.dx64fsl -o -name \*.dx32fsl -o -name \*.fx64fsl -o -name \*.fx32fsl -o -name \*.sx64fsl -o -name \*.sx32fsl -o -name \*.wx64fsl -o -name \*.wx32fsl -o -name \*.fasl -o -name \*.ufsl -o -name \*.fsl -o -name \*.dxl -o -name \*.lo -o -name \*.la -o -name \*.gmo -o -name \*.mo -o -name \*.toc -o -name \*.aux -o -name \*.cp -o -name \*.fn -o -name \*.ky -o -name \*.pg -o -name \*.tp -o -name \*.vr -o -name \*.cps -o -name \*.fns -o -name \*.kys -o -name \*.pgs -o -name \*.tps -o -name \*.vrs -o -name \*.pyc -o -name \*.pyo \) -prune -o  -type f \( -name \* -o -name .\* \) -exec grep -i --color -nH -e emacs {} +

It looks crazy. Put it in a function so you
don't have to see it at all?

(defun my-grep(pattern file-name)
  "My own version of grep command"
  (interactive "sPattern: \nFFind %s in file(s): ")
  (let ((cmd "grep -e"))
    ;;       ^^^^^^^^^ My Grep Command

If I understand correctly, you requires the change of command as
mentioned here.

Only GNU Grep has that option, AFAIR.

On second thoughts, the following set should be helpful:

(defun my-grep-base(grep-cmd params)
  (grep (format "%s %s %s" grep-cmd (car params) (cadr params))))

(defun my-grep-params(pattern file-name)
  "My own version of grep command"
  (interactive "sPattern: \nFFind %s in file(s): ")
  (list pattern file-name))

(defun my-grep()
  (interactive)
  (my-grep-base "grep -e" (call-interactively #'my-grep-params)))

(defun my-lgrep()
  (interactive)
  (my-grep-base "lgrep -e" (call-interactively #'my-grep-params)))

(defun my-rgrep()
  (interactive)
  (my-grep-base "rgrep -e" (call-interactively #'my-grep-params)))

and you can define lgrep and rgrep in your .bashrc (or .bash_aliases) as follows:

alias lgrep='grep -n '
alias rgrep='grep -nR '

Does posix grep support the currently used --exclude option?
Doesnt show for example here http://www.unix.com/man-page/posix/1p/grep/

Raghav thanks for your attempt.
I'll try and get back on how it goes
Do consider incorporating the exclude-from option
I believe its easier for lgrep, harder for rgrep

Thanks for trying Raghav but as of now it does:

And when I change the lgrep defun to:

(defun my-lgrep()
  (interactive)
  (my-grep-base "grep -e" (call-interactively #'my-grep-params)))

in order to remove gratuitous dependency on a shell lgrep

I get:

Grep started at Fri Jul  8 08:40:04

For now with:

grep-find-ignored-directories set to (".git" ".hg" "__pycache__")))

and

grep-find-ignored-files set to  (".#*" "*.o" "*.elc" "*.pyc")))

I get things like this:

-*- mode: grep; default-directory: "~/vit-projects-common-wiki/" -*-
Grep started at Fri Jul  8 08:48:12

grep  --exclude=.\#\* --exclude=\*.o --exclude=\*.elc --exclude=\*.pyc -i --color -nH -e emacs * .*
followed by the real grep output
without too many false positives

Sure one line of output would be better than 4 but its ok ... can live with it

Try the following in your command line:

$ alias lgrep
alias lgrep='grep -n '

or something like that should be ouput.


If this is not the case, The problem is about configuring your shell
environment for emacs, not the emacs itself
