c++ and c common mode

c++ and c common mode

[Hadron Quark]

I am duplicating hook additions e.g

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

Is there not a "common c/c++ hook" or have I messed up?

I think this line is sufficient.

I don't have this variable in Emacs CVS.

A great example of not staying up too late when messing around with
your setup - you are quite correct. I was sure I had checked that. Works
fine. *slaps forehead*.

The one line I *did* have to duplicate was the define-key to add to both
keyboard maps:


,----
|   (let ((dl '(
| 	      ([f1] . jump-man-page)
| 	      ([backtab] . semantic-ia-complete-symbol)
| 	      ([f5] . find-tag-noconfirm)
| 	      ([f6] . find-tag-repeat)
| 	      ([f7] . pop-tag-mark)
| 	      ([f2] . gdb-restore-windows)
| 	      ([f10] . compile)
| 	      ([f11] . next-error)
| 	      ([f12] . gdba))))
|     (dolist (i dl)
|       (define-key c-mode-map (car i) (cdr i))
|       (define-key c++-mode-map (car i) (cdr i))
|       ))
`----

is there a better way? Some common "subset" for "c like" files?

Add-hook just adds a function, so why not put the above in a function?

It is : it was just an extract to show the duplication of the define-key lines.

Ah, I'm with yer now.  You could do:-

(defun define-key-c-and-c++-map (key x)
  (define-key c-mode-map key x)
  (define-key c++-mode-map key y))

Thanks, but  I realise that - not much of a saving IMO and more
cluttering up of name space. I guess I was asking if there is a "base
key map" shared by all "c like" file modes so I only have to define-key
once. No big deal I agree, but was just trying to tidy my emacs
libraries which are full of this & that at the moment as I built up my
emacs gdb support knowledge.

Inside CC-mode there is such a beast, it's called c-mode-base-map.
It would be generally useful if it were possible to change it in Emacs
configuration.  Try asking the CC-mode maintainer if they would
consider making it a variable users can set.

Use `c-mode-base-map' or if needed `local-set-key'.

It was changeable! Thanks for your help.
