Auto revert mode but only for git projects

Auto revert mode but only for git projects

[Andrea Crotti]

When using branches with emacs reverting the buffers can be quite
tedious.

But also activating auto-revert-mode everywhere is not such a good idea.

So I thought that I could automatically activate auto-revert-mode BUT
only when
1. I'm in a git repo
2. I have at least 2 branches

What could be the cleaner way to do it?
Textmate.el has already something to look if it's a git repo, then I can
check for more branches with
--8<---------------cut here---------------start------------->8---
git branch | wc -l
--8<---------------cut here---------------end--------------->8---
for example and maybe add a hook in find-file-hooks?

Could that work?

I solved with something like this:
--8<---------------cut here---------------start------------->8---
(defun is-git-file ()
    "Return nil unless the file is in the git files"
    (if
        (member (file-name-nondirectory buffer-file-name)
                (split-string  (shell-command-to-string "git ls-files")))
        (auto-revert-mode t)))
  
  (add-hook 'find-file-hook 'is-git-file)
--8<---------------cut here---------------end--------------->8---

It doesn't really make sense to look at branches since for every pull we
could have to revert...
Apparently it's working, if you have some hints/complaints/suggestions
don't hesitate
