choose input method automatically

choose input method automatically

[Simon Strobl]

Hello,

if a file starts with

 -*- coding: utf-8;-*-

emacs will automatically set the coding to utf-8. Is there something analogous for
the input method?

I would try adding this in -*-...-*-:

eval: (set-input-method "foo")

There's a gotcha with that --- if you don't want emacs forcing you to
confirm the local eval each time you read one of these files, you'll
need to frob enable-local-eval, as described in the "File Local
Variables" section of the emacs manual (excerpted below):

,----
|    The `eval' "variable," and certain actual variables, create a
| special risk; when you visit someone else's file, local variable
| specifications for these could affect your Emacs in arbitrary ways.
| Therefore, the option `enable-local-eval' controls whether Emacs
| processes `eval' variables, as well variables with names that end in
| `-hook', `-hooks', `-function' or `-functions', and certain other
| variables.  The three possibilities for the option's value are `t',
| `nil', and anything else, just as for `enable-local-variables'.  The
| default is `maybe', which is neither `t' nor `nil', so normally Emacs
| does ask for confirmation about file settings for these variables.

If you want to avoid both (confirming each time as well as frobbing
enable-local-eval) you could set some variable of your own in the
local variables section (everything below is untested)  …

-*- my-input-method: lirum-larum -*-

… and then put something like this into your .emacs:


(defvar my-input-method nil
  "Preferred input method local to a file.
This variable is meant to be set in the local variables section.")
(make-variable-buffer-local 'my-input-method)

;; When visiting a file, check whether `my-input-method' is non-nil
;; and set the current input method accordingly.
(add-hook 'find-file-hooks
	  (lambda ()
	    (when my-input-method
	      ;; I seem to recall that the argument to
	      ;; `set-input-method' is supposed to be a string, but I
	      ;; can't check right now.
	      (set-input-method (symbol-name my-input-method)))))



I think this method would also be useful for setting up file-specific
indentation styles, btw.

Thanks a lot. In order to set input-method *and* coding automatically,
I have put the following in the first line of my file:

% -*- coding: utf-8; my-input-method: u8tex; -*-

(For those who have the same problem: Replace % by the specific
comment character you need for your type of file.)

Having a coding line and a my-input-method line at the same time did
not work.

Thanks to all who participated in this thread.
