SDCV and indian diacritics

SDCV and indian diacritics

[Sebastian Nehrdich]

Hello everybody,
I am new to this list and didn't do anything with my emacs for some time,
so please be patient if I am not giving the right/enough information. :)

Lately I set up my emacs to work with SDVC via the sdvc.el extension, as
described here: http://www.emacswiki.org/emacs-de/Sdcv

So far it is working alright and it really is a handy tool for me, but one
problem keeps bothering me.
Mostly I am using emacs to set Sanskrit texts wich usually contain a lot of
diacritics.
this might look like this: dṛṣṭvādḍhataṃ rūpamugraṃ tavedaṃ
And the dictionary files contain the words in the ITRANS / Harvard-Kyoto
transliteration sheme, wich is used to set Devanagari-letters in the roman
alphabet without using diacritics at all.
So when I want to run sdcv on my input wich includes diacritis, naturally
it does not work well because the dict-files are in ITRANS/Harvad-Kyoto
transliteration.
Of course, if I replace the diacritics manually and turn the input into
something like this:
dRSTVAdDhataM rUpamugraM tavedaM
wich is in conformity to the ITRANS/Harvad-Kyoto transliteration, sdcv is
working very well. But I do not want to input all my stuff in ITRANS
because I might want to use it later for latex etc.
So my question is: Is it possible to hack the sdcv.el to do this
replacement so I can type with my diacritics, then the sdcv.el converts all
the characters to itrans before the input is sent to sdcv?
Greetings & thanks for any advice on this

Sebastian

No idea about sdcv
I have a bit of elisp that goes the other way.
You type in ASCII/ITRANS
That code then batch-runs the Itrans input method on the buffer and generates another buffer with devanagari.
You could presumably change the input method to diacritics (Dunno... Just an idea)

I could pass on that code to you. [Not on that machine now]

Heres the code
To use:
0. Load this code
1. Visit a file (cant be a file-less buffer) that has ITrans devanagari
2. Press f4
    (should open a new frame having the devanagari)

Notes:
1. You can keep pressing f4 to check the two views are in sync
2. If your diacritics are done by an emacs input method, then all you have to do is replace the defvar input-method by whatever you are using.
Of course if you are using something at OS or h/w level (like a different keyboard) then sorry you are not in luck (for this method)

        (out-buf-name (concat (file-name-sans-extension filename)
                               "-hi" (file-name-extension filename t)))
