Key binding in local keymap problem

Key binding in local keymap problem

[etay.meiri]

Hi,

I have the following line in my .emacs:

(define-key gud-mode-map [f9] 'gud-break)

and I get an error that the value of gud-mode-map is void.

Here's the full log:

An error has occurred while loading `/home/cl/.emacs':

Symbol's value as variable is void: gud-mode-map

Any idea?

Thanks,

You need to load library `gud' before you do that.
It defines variable `gud-mode-map' and gives it a value.

So, if you don't want to load `gud' on Emacs start-up, use `add-hook':

(add-hook 'gud-mode-hook
          (lambda () (define-key gud-mode-map [f9] 'gud-break)))

Yes, I should have added that. Thanks.

I think it's cleaner to do the customizations like this:

(eval-after-load 'gud '(define-key gud-mode-map [f9] 'gud-break))

So they aren't executed every time the mode is started.
