rebinding iso keys

rebinding iso keys

[josh]

Hi,

I have a german keyboard and would like to rebind the characters "ä"
"ö"
"ü" and also "ß" to functions, replacing the self-insert function,
but I
can't find the right vector code or whatever for the keys.

For example, I've tried the following variations (from my .emacs):

(defun TeX-parenth () (interactive) (TeX-Inserting ?\\ "("  "()"))
(defun TeX-a-umlaut () (interactive) (insert "\"") (insert "a"))

(add-hook 'LaTeX-mode-hook
	  '(lambda ()
	     ;; Begin bracket closing
	     (local-set-key  "(" 'TeX-parenth)

	     (local-set-key "ä" 'TeX-a-umlaut)
	     (local-set-key [?\xe4] 'TeX-a-umlaut)   ;iso ?
	     (local-set-key [?\xc384] 'TeX-A-umlaut) ;unicode ?

))

It works for the parenthesis, but not for "ä", and actually, I would
like to
keep my .emacs in ascii, so I don't really even want the "ä"
variation.

Two questions:
1) what am I doing wrong and

2)How can I capture the right vector code that the keyboard sends to
emacs when I press "ä", so I can bind it properly?


Thanks,

Josh

Try to set the keys interactively first. Then do repeat-complex- 
command and grab and save the interactive key binding:

	C-x ESC ESC C-a C-k C-g C-x b .emacs RET C-y C-x C-s

You could start your .emacs file with

	;;; -*- mode: lisp; coding: us-ascii; -*-

The variable file-coding-system-alist could be set to handle files  
ending in .emacs to be of a certain coding system ...

Hi Peter,

Thanks for your reply, it worked!

I still have two questions:

1) binding interactively, executing repeat-complex-command, and then
yanking out of the mini-buffer was certainly a clever idea to get what
I wanted, but what's the "real" way? Is there no way to look up the
correct code? Where is it stored?

2) what was wrong with what I tried:

             (local-set-key "ä" 'TeX-a-umlaut)
             (local-set-key [?\xe4] 'TeX-a-umlaut)   ;iso ?
             (local-set-key [?\xc384] 'TeX-A-umlaut) ;unicode ?

These are all /your/ ideas about this "key code." Obviously GNU Emacs  
has its own. What is GNU Emacs' idea of ä, i.e. what is your code?

Hi Peter,

yes (except that "ä" should still be "ä"), which is why I asked
question number 1) above:

So, where is this stored, and how can I look up the code? Like I said,
using repeat-complex-command was clever, but what's the "real" way of
doing this?

You can position the cursor over the character in a buffer (ä in this
case), and use `C-x =' to see its "emacs code".

Hi Miles,

cool, thanks! This clears up some of my confusion, since C-x = produces

Char: ä (04344, 2276, 0x8e4, file ...) point=192 of 192 (99%) column 0

and now not only does the following (produced using
repeat-complex-command as suggested above) work:

(local-set-key (quote [2276]) (quote TeX-a-umlaut))

but also

(local-set-key [?\x8e4] 'TeX-a-umlaut)

e4 being the iso code for "ä" (as I recall, at least). My last
question is now, why the "8" ?

I can't tell! I think I've seen a few times that the data C-h k gave  
me did not work in global-set-key. From this list I knew this trick  
and use it excessively and successfully.

I think GNU Emacs uses environment variables like LC_CTYPE, LC_ALL,  
LANG to determine in which format data from the keyboard enters. I  
have some UTF-8 set. I have from this setting the problem of  
converting UTF-8 to ISO 8859-15 encoding as used in my .emacs. When  
you use the trick of interactively binding a key and retrieving it  
with repeat-complex-command, you insert for example UTF-8 data from  
the keyboard that is automatically converted into ISO 8859-15 format!

Variables and commands used in this area are set-keyboard-coding- 
system, set-terminal-coding-system, set-clipboard-coding-system, set- 
selection-coding-system, ...

E4 is indeed the ISO 8859-X code for "ä", but that is not the point
here. 8E4 is the code point for the character "ä" (well, for one of
the "ä"-characters) in Emacs internal coding system `emacs-mule'.
