Input Method for Indian Script

Input Method for Indian Script

Hi Everyone,

Is there any way I can add a new input method for Bengali in Emacs ?

There are two input methods right now,
1. bengali-inscript,
2. bengali-itrans.


I would like to add another input method which will be like
bengali-inscript, with fixed, or touch
typing based keyboard layout.

Is it possible to add a layout like "Probhat" or "Bijoy" ? (reference:
http://en.wikipedia.org/wiki/Bengali_input_methods ,
http://en.wikipedia.org/wiki/File:KB-Bengali-Probhat.svg ).

I will appreciate if someone can tell me whether implementing one of these
fixed keyboard layout can be done with minimal effort.


Thank you,

Do you mean that the current bengali-inscript is incorrect
and thus it should be "fixed"?  Or, you just want the
different behavior?

If those input methods are context free (i.e. the same key
(sequnece) always produces the same character(s)), making
a new input method is easy.

============================================================
(quail-define-package "Probhat" "Bengali" TITLE t DOC-STRING
                      nil t t t t nil nil nil nil nil t)
(quail-define-rules
  (KEY CHAR)
  ...)

;; See the docstrings of quail-define-package and
;; quail-define-rules.
============================================================

But, if an input method is not context free (e.g. the key
"a" produces different charaters depending on what you have
already typed), you need some Emacs Lisp programming skill.

Hi Kenichi,

I think the current input methods are fine,
I just want to add additional methods for bengali.

I want to start with Context Free one. Thanks for the hint.
I am going to look around the quali-define-* functions.

Thanks,
Mahmudul Hasan
