BTW, though that fix seems obviously correct to me, I won't commit it
unless someone who actually uses Indian input methods tests it.
For all I know, something somewhere else assumes "dev-aiba".
(It's broken all the way back to Emacs 22.1.)

(Refer http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11103)

I am copying Rustom who has more understanding of devanagari. He can
suggest the default input method to go with that particular language
environment and also test your earlier patch.

C-h L Devanagari actually gives the following output

Devanagari language environment

Such languages using Devanagari script as Hindi and Marathi
are supported in this language environment.

Input methods:
  devanagari-inscript ("DevIS" in mode line)
  devanagari-aiba ("DevAB" in mode line)
  devanagari-kyoto-harvard ("DevKH" in mode line)
  devanagari-itrans ("DevIT" in mode line)

Character sets:
  unicode: Unicode (ISO10646)

Coding systems:
  utf-8 (`U' in mode line):
	UTF-8 (no signature (BOM))
	(alias: utf-8 mule-utf-8)

[back]

My 2 cents will be that the current defaults of devanagari-aiba need
to be changed to devanagari-itrans. I don't speak the language that
uses devanagari script.

Sorry I dont get the context.
On my emacs 23.3.1 I can activate devanagari-aiba input method.
Is there something else you want me to check?
I dont know this input method (and google does not help) but looking at
describe-input-method and trying out a bit it seems very close
(identical??) to itrans.

You can ignore this mail, if you want.

Rustom,

Here is the context -

> Sorry I dont get the context.

> Is there something else you want me to check?

Are you activating the input method like this - 

1. C-x C-m l Devanagari
2. C-\

Do you see a crash like this -

Debugger entered--Lisp error: (error "Can't activate input method `dev-aiba'")
  signal(error ("Can't activate input method `dev-aiba'"))

See [1]. They apparently has something to do with diacritic marks
(whatever that means).

> but looking at describe-input-method and trying out a bit it seems
> very close (identical??) to itrans.

See [2].  The table that compares two methods and is attached here for
future reference.  There are 12 entries in that table where the aiba and
itrans input methods differ.

I was wondering, as someone who is more familiar with Devanagari which
of these would you prefer as the input method.  If you think that you
have no particular opinion, I think we can leave the defaults as such.

Here is an entry for SHA.

I applied this patch. 

I continue to get the orignal crash. 

Quick look suggests that language-info-alist (right after emacs -Q and
no intervening commands) continues to refer to "dev-aiba".

As a result when I do, C-x C-m l Devanagari, the `default-input-method'
picked up is "dev-aiba".

This results in a crash when I do C-\

Please don't call "a crash" something that is merely an error.

If I do it like you say I only see
Can't activate input method `dev-aiba'


No backtrace.

If I do what I usually do ie C-x RET C-\
and then give devanagari-aiba (not dev-aiba) it seems to work for me

My preferences later (I'll look more carefully at both)

Mine doesn't. You need to rebuild Emacs to pick up the change. Did you
do that? You need to get leim-list.el regenerated. I don't know the
minimum steps needed for that, so, as always, I suggest bootstrapping.

I get devanagari-aiba.

Ok.

No. I wasn't aware of it. It's all new to me.

I rely only on binaries. I have not built Emacs at all and I don't want
to build one.

Check your fix in. Once Christopher Scholtes makes available a new
binary build, I will update the status of this bug. Meanwhile Rustom
might have also made his opinion on whether he wants aiba or itrans by
default.

Version: 24.0.95

Fair enough, I checked it in.
If you think there should be actual changes to the input method, I
suggest making a new report with the details. Followup to this report if
there turns out to be some problem with the fix for the input method not
working at all.
