.emacs key maps are overwritten by php-mode

.emacs key maps are overwritten by php-mode

[Stefan Horomnea]

Hello,
I write something in my .emacs file like this:
(global-set-key [(control ?d)] 'kill-ring-save)

This works fine, in other modes (text, html, etc.). But when I open a 
php file, my Ctrl+d instead of kill-ring-save does 
c-electric-delete-forward .
And I have several commands in my .emacs file, that are broken by the 
loading of the php-mode. What's the catch ?

Thank you.

Stefan

There is a convention that major modes should use, see "(elisp) Key 
Binding Conventions" (maybe this is only find in current CVS Emacs?):

   * Please do not define `C-c LETTER' as a key in Lisp programs.
     Sequences consisting of `C-c' and a letter (either upper or lower
     case) are reserved for users; they are the *only* sequences
     reserved for users, so do not block them.

So the php-mode you use does not follow this convention. Perhaps it 
would be good to contact the author?

Hello,

I think I don't understand. I have just Control+D, and not Control-C and 
a Letter.
If I only find a way to load my .emacs file or some other file with my 
keybindings after the last mode has loaded and overwrite those ?

Sure you do not understand when I give you the wrong answer ;-)

Sorry, my mistake. I thought you where using 'C-c d'. That is a sequence 
reserved for users (see below). If you really want to overwrite a 
binding in a major mode you can do that in the mode hook. Mode hooks are 
run as the last thing when a mode is setup. For php-mode the hook should 
be called php-mode-hook, they are always named like that. Use add-hook 
to add a function that set up the key binding for you. Something like

   (add-hook 'php-mode-hook
           (lambda()
             (local-set-key ....)
            )

Here you should use local-set-key instead of global-set-key. This way 
you change the major modes keymap.

Huch?  C-d is not `C-c LETTER'.

The Emacs manual explains Stefan too (in the last sentence):

,----[ (info "(emacs)Keymaps") ]

| may be overridden by certain extensions or major modes which redefine
| the same key.
`----

This, as well as your quote from (info "(elisp)Coding Conventions")
was already present in Emacs 21.

Bye, Reiner.

Php-mode uses its own php-mode-map. You would need to change this  
map ...
