Lisp error when using M-x

Lisp error when using M-x

[wael-zwaiter]

Am getting a problem when hitting M-x, with the following error.

Debugger entered--Lisp error: (wrong-type-argument commandp counsel-M-x)
  call-interactively(counsel-M-x nil nil)
  command-execute(counsel-M-x)

Re: Lisp error when using M-x

The problem occurs with ivy as follows.  How is best to have the keybindings?

  (require 'ivy)
  (ivy-mode 1)
  (setq ivy-use-virtual-buffers t)
  (setq ivy-count-format "(%d/%d) ")

  (global-set-key (kbd "C-s") 'swiper-isearch)
  (global-set-key (kbd "M-x") 'counsel-M-x)
  (global-set-key (kbd "C-x C-f") 'counsel-find-file)
  (global-set-key (kbd "M-y") 'counsel-yank-pop)
  (global-set-key (kbd "<f1> f") 'counsel-describe-function)
  (global-set-key (kbd "<f1> v") 'counsel-describe-variable)
  (global-set-key (kbd "<f1> l") 'counsel-find-library)
  (global-set-key (kbd "<f2> i") 'counsel-info-lookup-symbol)
  (global-set-key (kbd "<f2> u") 'counsel-unicode-char)
  (global-set-key (kbd "<f2> j") 'counsel-set-variable)
  (global-set-key (kbd "C-x b") 'ivy-switch-buffer)
  (global-set-key (kbd "C-c v") 'ivy-push-view)
  (global-set-key (kbd "C-c V") 'ivy-pop-view)  )

Probably you need a (require 'counsel) and a (require 'swiper) as well
before those two lines.

How did you install `ivy`?  The normal installation via `package.el`
should make the above `require` unnecessary.

But shouldn't those packages's autoloads take care of that already?

I am using ivy from source.

If you say so

Have done

(global-unset-key (kbd "C-i"))

But, C-i is still doing TAB.

IIRC a few key bindings are hard-coded. You can set the key binding to
something else, but you can't remove the "base" binding.

If you don't want C-i to do TAB, you can set the binding to a do-nothing
command:

(global-set-key (kbd "C-i") (lambda () (interactive)))

Re: Lisp error when using M-x

[wael-zwaiter]

I want to use C-i for ivy related commands.

  (global-set-key (kbd "C-i C-s") 'swiper)
  (global-set-key (kbd "C-i C-r") 'ivy-resume)
  (global-set-key (kbd "C-i C-i") 'ivy-resume)
  (global-set-key (kbd "C-i M-x") 'counsel-M-x)
  (global-set-key (kbd "C-i C-f") 'counsel-find-file)

For that you need to convert C-i to a prefix key. This seems to work:

(defvar cikm (make-keymap))
(global-set-key (kbd "C-i") cikm)
(global-set-key (kbd "C-i C-s") (lambda () (interactive) (message "hi!")))

Please note that Emacs has some guidelines about choosing keybindings:
some are reserved for users, some for external packages and some others
for Emacs itself.

See the "Key Bindings" node in the Emacs manual.

Hitting C-i it is still saying TAB.

Just a bit of general advice....

In Emacs if the keys beginning with C-c followed by an unescaped letter
are reserved for the user.  For example "C-c a" or "C-c b".  That prefix
is specifically for the user adding things.  If you add thing there then
they certainly won't collide with other things.  Note that the keys
beginning C-c and ending with another ctrl key are used by major modes.
So, although "C-c a" will always be free "C-c C-a" is probably used.

Secondly, if you want to use counsel then I suggest replacing the
standard keybindings.  Replace M-x with counsel-M-x, there is no reason
to have both of them.  The same is true of find-file, you may as well
just over-ride "C-x C-f" with counsel-find-file.  So you may as well
just do:

(global-set-key (kbd "M-x") 'counsel-M-x)
(global-set-key (kbd "C-x C-f") 'counsel-find-file)

This is what the Ivy/counsel/swiper manual suggests.  Try it out and see
if you like it.  If you don't you can go back to the original in-built
version or try out the other alternatives.

For the other keys I would do this:

(global-set-key (kbd "C-c s") 'swiper)
(global-set-key (kbd "C-c r") 'ivy-resume)

Lastly, if you want to use Emacs in a terminal emulator then there's a
problem with C-i.  In a terminal emulator (or a linux console screen)
C-i and tab always do the same thing.  So, if you press tab it will do
the same thing as C-i.  In your case that means it'll run your prefix
key.  So, there will be no way to press tab in the terminal.  This is
not an Emacs problem, it's a problem of the interface between
terminal-emulators and programs.  For some of these keys it can be fixed
by changing terminal configuration.
