Is there a way to activate (inhibit-message) only for particular modes or buffers?

Question

Is there any way to turn on (inhibit-message) only for particular modes or buffers or frames or windows? (any of those would do)

Answer 1

inhibit-message is a variable (added in 25.1), not a function (I mention this because you've written it like a function call).

Therefore you can set its value buffer-locally:

(setq-local inhibit-message t)

Where you would do that would depend on your specific requirements.

For a particular mode you can use the associated mode hook. For foo-mode you would use:

(add-hook 'foo-mode-hook 'my-inhibit-buffer-messages)

(defun my-inhibit-buffer-messages ()
  "Set `inhibit-message' buffer-locally."
  (setq-local inhibit-message t))

Note that a more typical use for the variable would be to let-bind it around some specific code:

(let ((inhibit-message t))
  ...)
