I'm working with Emacs on windows, I usually work locally, but I want to disable magit when I'm working on a remote file.

I'm trying to add a hook that disables magit when it detects that the file is on a remote server. I tried this snippet but it freezes tramp everytime I try to open a remote file:

(use-package magit
    :ensure t
       (lambda () (when (file-remote-p default-directory) (magit-mode -1)))))

    What exactly are you trying to disable? magit-mode is a major mode for magit buffers, not something that is enabled in specific source files. Jan 21, 2021 at 13:37
  • I don't want magit to run git on the remote server everytime I open a file with Tramp. I just want it to work if I'm working with a file on my local machine. I don't know if that's possible really.

  • I'm not sure if this is an answer or not for you, but Magit mentions a fix for bad performance when using TRAMP in it's docs here: you might try their snippet out. magit.vc/manual/magit/Performance.html Jan 21, 2021 at 18:21

I don't think Magit will be responsible for that; but vc might?

See whether vc-ignore-dir-regexp helps. That has a default value of:


For ease of editing and reading, let's use rx syntax. The excellent xr package on GNU ELPA gives me the following rx syntax for the default vc-ignore-dir-regexp value:

(seq bos (or (seq (any "/\\") (any "/\\")
                  (one-or-more (not (any "/\\")))
                  (any "/\\"))
             (seq "/" (or "net" "afs" "...") "/"))

So let's try the following. I'm using tramp-methods to establish the remote path syntax possibilities.

n.b. The position of the (eval-when-compile (require 'tramp)) looks very odd, but our usage of the rx macro needs tramp-methods to be defined at byte-compile time, and this achieves that without unnecessarily loading tramp in other circumstances. We could alternatively use the rx-to-string function instead of the rx macro, but this way we retain the slight compile-time performance benefit.

(with-eval-after-load "tramp"
  (eval-when-compile (require 'tramp))
  (setq vc-ignore-dir-regexp
        (rx (seq bos
                 (or (seq (any "/\\") (any "/\\")
                          (one-or-more (not (any "/\\")))
                          (any "/\\"))
                     (seq "/" (or "net" "afs" "...") "/")
                     ;; Ignore all tramp paths.
                     (seq "/"
                          (eval (cons 'or (mapcar #'car tramp-methods)))
                          (zero-or-more anything)))
  • I have put the last code in my init.el file, but sometimes when I byte-compile this file, it complains about tramp-methods not being defined. Apparently this happens when tramp wasn't loaded before byte-compiling, which of course happens when I had not used any tramp files before in this session. However, I don't understand why it needs the value of tramp-methods when compiling this. I thought it would only need it after loading tramp.el, and then tramp-methods would be defined. I'm now trying to solve this by including (eval-when-compile (require 'tramp)) in my init.el. Dec 12, 2022 at 11:14
  • Ah, yes indeed. rx is a macro, so it gets expanded at compile-time. I think you'll be able to handle this with the somewhat odd nesting of (with-eval-after-load "tramp" (eval-when-compile (require 'tramp)) ...). I'll edit the answer.
