Provide mechanism to disable for some modes

[alephnull]

Like markdown-mode already has excellent prompt support when you are editing and which-key takes it over. I tried setting up a local variable in markdown-mode-hook like:

(lambda () 
   (setq-local which-key-idle-delay 60))

and I can see that the variable is set in buffer but w-k seems to be using the default value. ANy other way of disabling also welcome.

That won't work unless you reset the timer each time you enter and exit the buffer.

You could try something like this instead

(add-hook 'which-key-delay-functions
          (lambda (_ _)
            (when (eq major-mode 'markdown-mode)
              1000))
          nil t)

@alephnull you can set markdown-enable-prefix-prompts to nil instead :)

The which-key-delay-functions trick works well and is very helpful for me in vterm. Add this to the docs maybe?

Seconded on the delay functions trick as a solution in vterm, though I feel a list of disabled modes would be a cleaner solution.

Here's my take on a 2s added delay to make evil and leader keybindings work in vterm with doom emacs without which-key interfering with the cursor placement.

(after! which-key
  (defun t/delayed-which-key (_ _)
    (cond
     ((eq major-mode 'vterm-mode) 2)
     (t nil)))
  (add-hook! 'which-key-delay-functions #'t/delayed-which-key))
