Re: Input Method for Indian Script

[Mahmudul Hasan]

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

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.
