Disable Annoying Audio Notifications

January 30, 2024

By default Emacs ring the bell to attract the user's attention, this is annoying.

To get a visual signal instead, set visual-bell with t Emacs should flash the screen to represent a bell.

We can also customize ring-bell-function to just flash the modeline.

;;;###autoload
(defun dotemacs-ring-bell-fn ()
  "Blink the mode-line."
  (let ((buf (current-buffer)))
    (invert-face 'mode-line)
    (run-with-timer 0.05 nil
                    (lambda ()
                      (with-current-buffer buf
                        (invert-face 'mode-line))))))

(setq ring-bell-function 'dotemacs-ring-bell-fn
      visible-bell t)
