After a recent update eldoc is turned on by default, even for emacs -Q. I don't appreciate the noise it generates when I'm using eval-expression. How do I turn it off?

Disable it globally:

(global-eldoc-mode -1)

Disable it locally - make sure that eldoc-mode is nil in all your buffers.

A less drastic solution would be to increase eldoc-idle-delay.

    Nope, doesn't work.

  • check buffer-local values of eldoc-mode.

  • Setting eldoc-idle-delay works, but how would I disable eldoc-mode for minibuffer? I tried minibuffer-setup-hook, it didn't work.

    It should be (global-eldoc-mode -1): nil for minor modes used to mean "toggle" but nowadays it means "enable".

    Because "toggle" is virtually never the behavior that's needed when called non-interactively. This change fixed latent bugs for all those people who had (add-hook 'foo-mode-hook 'bar-mode) in their .emacs. A side-benefit is that we don't need any turn-on-foo-mode any more.

If you want to control the behavior from the minibuffer when using eval-expression, use eval-expression-minibuffer-setup-hook.

For example, if you have eldoc on globally and want it off only in this one case, use:

(defun turn-off-eldoc () (eldoc-mode -1))
(add-hook 'eval-expression-minibuffer-setup-hook #'turn-off-eldoc)

This hook is new in Emacs 24.4.

  • The answer from @sds is exactly right if you do not want to use eldoc at all. However from your question it sounds like you are specifically interested in disabling eldoc when using eval-expression. Another option of course is to disable eldoc globally and then use hooks to selectively turn in on, e.g. (add-hook 'emacs-lisp-mode-hook #'eldoc-mode)
