Often I have many buffers open and, for whatever reason, I no longer wish to use a particular minor mode with them. Is there currently a built-in way to disable a particular minor mode for all open buffers, or does this require writing a custom elisp function?


This does require a custom elisp function unless the minor mode has a (global-*-mode) function attached to it.

Luckily, it is a pretty simple function:

(defun global-disable-mode (mode-fn)
  "Disable `MODE-FN' in ALL buffers."
  (interactive "a")
  (dolist (buffer (buffer-list))
    (with-current-buffer buffer
      (funcall mode-fn -1))))

To use (for example, on projectile-mode):

(global-disable-mode 'projectile-mode)

Or call it interactively:

M-x global-disable-mode RET projectile-mode

    Seems to work! And nicely written to boot. Thank you very much. =) – holocronweaver Dec 20 '14 at 22:31
  • alternatively, if you only need this one time, you can just copy Eval the body of the function: M-S-; (dolist ....) and replace mode-fn with 'projectile-mode in this case. – Old account Oct 30 '15 at 15:04
