I noticed I never see in the mode line in which VCS branch I'm currently in, when I open a file in Emacs.

So I tried it with an empty Emacs, created a folder in Eshell, called ~/foo , and initialized Git with git init inside ~/foo. Then I have Emacs created a buffer inside ~/foo with M-x find-file bar.txt. I saved the file, and in Eshell I did [user ~/foo] git add bar.txt.

But I don't see any VCS-related in the mode line. When I run C-x v = Emacs tells me that bar.txt is not under version control. And the same story when I revert the buffer.

When I do the following M-: (eval (executable-find "git"), it pointed to /usr/bin/git which is correct.

Auto-revert-modedidn't help it. What else can I do in order to figure out how this issue is caused? Git in terminal tells me that bar.txt is recognized and tracked by Git.

    M-: is a command to evaluate an expression, so there's no need to use eval within it.

  • Have you tried with emacs -Q?

The VC packages uses caching, and in many places assumes that the user interacts with VCS systems (e.g. Git) through it.

To register a new file in a Git repository, press C-x v v, you don't need to use Eshell for that.

If you've changed a buffer's status using something else than VC commands, though, you can visit the file again to refresh the status information. The easiest way to do that, IMO, is M-x revert-buffer.

Also make sure that vc-handled-backends includes Git, which it does by default.

  • Thanks for your response. I tried C-x v v and I got only the message "Use VC backend:" with an empty list in helm-mode-vc-next-action". Still no master or any branch in mode line.

  • Could you try running Emacs with -Q and then repeating the procedure again? I'm wondering if some other package or setting you've got enabled is causing the problem.

  • Helm is an obvious culprit, going by helm-mode-vc-next-action being present in the scenario.

  • I included (setq vc-handled-backends "Git") and evaluated it. But when I call C-x v v, I got the error Wrong type argument: symbolp, 71 and there is no command helm-mode-vc-next-action in M-x. What would you suggest?

    @ReneFroger That happens. VC doesn't know how to diff against a branch that contains zero revisions.

Use C-x C-v (find-alternate-file) to reload bar.txt. You should then see "Git@master" in the mode line.

Check your vc-git-program value. I just hit this issue and found that I had customised it (well actually vc-hg-program in my case) and the program was missing from the specified location.
