Can I turn off ivy-mode in comint buffers?

Can I turn off ivy-mode in comint buffers?

[bbenedetto]

Good day.

I have loaded ivy-mode and really like it... everywhere except in
comint buffers (for filename completion).  Is there some way to either
disable it in comint buffers or to just turn it on everywhere else?

Sorry if this is a pretty basic question.  I couldn't find an answer
either online or looking through the source.

Thanks!

I don't speak for Goodyear and they don't speak for me.  We're both happy.

One way to do it is to customize post-command-hook to dynamically turn
ivy on and off depending on the current buffer's major mode.

(ivy-mode 1) ; globally enabled

(defun disable-ivy-in-comint-only ()
  "Leave `ivy-mode' enabled everywhere except in buffers that derive
from `comint-mode'."
  (if (derived-mode-p 'comint-mode)
      (ivy-mode -1)
    (ivy-mode 1)))

(add-hook 'post-command-hook 'disable-ivy-in-comint-only)

AKA

   (ivy-mode (if (derived-mode-p 'comint-mode) -1 1))

Hmm... really?
You want to (re)enable/disable ivy-mode after every command?

Yeah, the command hooks are a blunt instrument.  I was able to get M-x
shell working with buffer-list-update-hook instead, but I had to add a
second hook to make sure it's disabled on the first buffer switch.

(ivy-mode 1)

;; Turn off ivy on first entry into a new comint-mode buffer.
(add-hook 'comint-mode-hook (lambda () (ivy-mode -1)))

;; Toggle ivy after every buffer switch, avoiding the minibuffer.
(add-hook 'buffer-list-update-hook
	  (lambda ()
	    (unless (eq major-mode 'minibuffer-inactive-mode)
	      (ivy-mode (if (derived-mode-p 'comint-mode) -1 1)))))

How's that?
