git diff/grep add --exclude option

Hi,

I was surprised to not find an option to exclude file from git diff/grep outputs like -x for diff or --exclude for grep. It's too bad because it can be really useful.

Is something like that is planned to be implemented by somebody? I would have loved to do it but unfortunately I'm no C developer.

Regards.

Yeah, me too, but probably because I never needed it ;) Anyway, there were some discussions on this before [1]. I thin a viable workaround is using ls-files and grep. Quick example:

git diff -- $(git ls-files | grep -Ev "(^Documentation|^compat/mingw.c)")

would show everything except the whole Documentation subtree and mingw.c from compat. Now, you might even whip that into your very own shellscript or use a git alias (dirty):

[alias]
  ediff = "!sh -c 'git diff -- $(git ls-files | grep -Ev $0)'"

And call it with 
  git ediff "(Documentation|compat/mingw.c)"
