Key binding problem

Key binding problem

[tubescreamer808]

Hi all,

I'm trying to bind a few keys in c mode and so far, didn't have much
success with it. I have the following defined in my .emacs:

(defun my-c-mode-common-hook ()
  (local-set-key [C-|] 'indent-region)
  (local-set-key [C-%] 'query-replace-regexp)
  (local-set-key (kbd "RET") 'newline-and-indent)
  (local-set-key [C-/] 'comment-region)
  (local-set-key [C-?] 'uncomment-region)
  (c-subword-mode 1)
  )

(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

The only binding that works is the one for the newline-and-indent
command. For the other ones, emacs tells me that the key combination
is not defined. However, if I run local-set-key interactively once
emacs is done loading and after visiting a C++ file, it works. I tried
the same bindings in c++-mode-hook but, unsurprisingly, it made no
difference at all which.

What am I doing wrong?

Thanks in advance
Jean

I don't know about this local-set-key command...

Could you try changing to something like these
  (define-key c-mode-map "\C-%" 'query-replace-regexp)
instead?

Cheers,

   (local-set-key KEY COMMAND)

   Give KEY a local binding as COMMAND.
   COMMAND is the command definition to use; usually it is
   a symbol naming an interactively-callable function.
   KEY is a key sequence; noninteractively, it is a string or vector
   of characters or event types, and non-ASCII characters with codes
   above 127 (such as ISO Latin-1) can be included if you use a
vector.

   The binding goes in the current buffer's local map,
   which in most cases is shared with all other buffers in the same
major mode.

I tried that also and got the same result.

Try

(local-set-key [(control ?|)] (lambda() (interactive) (message "Hi from 
C-|")))

Thank you very much weber, it works perfectly.

Alternatively, I have just discovered that using the kbd macro works
fine also e.g.
   (local-set-key (kbd "C-|") 'indent-region)

Don't ask me why I never tried it before since I was already using it
for the newline-and-indent binding. I guess that sometimes things are
just too obvious or you're just too stupid...

Anyways, thanks again for your help!

You are not stupid at all. The two versions are perfectly right

kbd macro is just "the new syntax" to define key bindings. It has
been introduced into emacs 20.x as far as I remember.

[()} is called the XEmacs way and has been supported (and is
still supported) by older emacs.

There is also the string syntax but I do not use it.

Not AFAIK. GNU Emacs 21 perhaps, but not GNU Emacs 20.

Hum I am pretty sure I have seen it introduced in emacs 20.1 or
something like that.

I may be wrong, I will have to check this.

Oops, I just noticed that I thanked weber for the solution but it was
in fact Lennart Borgman who came up with the answer. So, sorry about
that Lennart and thank you very much.

As always it is the intention that counts. I was fond to see you liked 
it and did not care that you thought someone else did it.

If there were some salaries involved I might have thought differently, 
but anyway in that case it is quite often so that no one cares about who 
actually does the job ;-)
