Indic script rendering bug is fixed.

[-- Attachment #1: Type: text/plain, Size: 605 bytes --]

I've just started my recently built GNU Emacs, from recently checked-out
From CVS 2-3 hours ago, and noticed that rendering is proper, and
doesn't require me to explicitly hint Emacs to use "Lohit Hindi" font
for rendering Devanagari text. Following is the version of GNU Emacs,
I'm running:

GNU Emacs 23.0.60.1 (x86_64-pc-linux-gnu, GTK+ Version 2.12.8) of 2008-05-29 on chateau

Thanks all :)

Good to know.  Thanks for checking.

23.0.60; Indic Script is not rendered properly

[Ashish Shukla]

In typing the text like "शुक्ल", I get this bug.

Following is the URL of screenshot of what I'm getting currently:
http://flickr.com/photos/wahjava/2525377097/

An earlier version of Emacs CVS used to render that correctly, as
shown in the following URL of screenshot:
http://flickr.com/photos/wahjava/2488290981/

I'm currently running emacs-cvs (checked-out an hour ago) port, in
Gentoo GNU/Linux :) .

Emacs is not crashed.

Please use C-u C-x = on a devanagari character to check
which font is used for it.

And also, if you know how to use gdb, please set break point
on Ffont_shape_text, and check why shaping doesn't work.

        OK. Here is my take on it.
 “मनोज श्रिवास्तव” is how to write my name; this is how an older version
 of emacs used to render it (correctly)

I typed characters क्ल and placed cursor on them, and then did C-u C-x =,
and following is the output.

---->8---->8----
        character: क (2325, #o4425, #x915)
preferred charset: unicode (Unicode (ISO10646))
       code point: 0x0915
           syntax: w 	which means: word
         category: i:Indian
         to input: type "ka" with devanagari-itrans
      buffer code: #xE0 #xA4 #x95
        file code: #xE0 #xA4 #x95
		   (encoded by coding system utf-8-unix)
          display:
		   composed to form "क्ल" (see below)

Composed with the following character(s) "्ल" using this font:
  -unknown-FreeSans-normal-normal-normal-*-12-*-*-*-*-0-iso10646-1
by these glyphs:
  [#<font-object "-unknown-FreeSans-normal-normal-normal-*-12-*-*-*-*-0-iso10646-1"> 17 -2 9 8 4]
  [0 2 2325 1210 9 9 0 8 1 nil]
  [0 2 2381 1265 0 -8 -11 0 3 [-3 -1 0]]
  [0 2 2354 1239 8 8 0 8 1 nil]

Character code properties are not shown: customize what to show

There are text properties here:
  auto-composed        t
  composition          [Show]
  fontified            t
---->8---->8----

Now I got that Emacs is using FreeSans font to render Devanagari
characters which is not expected, so I modified fontset-default to use
"Lohit Hindi-10" Xft font using following Elisp code:

---->8---->8----
(set-fontset-font "fontset-default"
(cons (decode-char 'ucs ?\x0900)
(decode-char 'ucs ?\x097f))
"Lohit Hindi-10")
---->8---->8----

And typed characters शुक्ल, and this time text got rendered perfectly and
following is the output of C-u C-x = on the text.

---->8---->8----
        character: क (2325, #o4425, #x915)
preferred charset: unicode (Unicode (ISO10646))
       code point: 0x0915
           syntax: w 	which means: word
         category: i:Indian
      buffer code: #xE0 #xA4 #x95
        file code: #xE0 #xA4 #x95 (encoded by coding system utf-8-emacs)
          display: composed to form "क्ल" (see below)

Composed with the following character(s) "्ल" using this font:
  -unknown-Lohit Hindi-normal-normal-normal-*-12-*-*-*-*-0-*-*
by these glyphs:
  [#<font-object "-unknown-Lohit Hindi-normal-normal-normal-*-12-*-*-*-*-0-*-*"> 16 8 7 8 0]
  [0 2 0 179 7 8 0 8 0 nil]
  [0 2 2354 65 9 9 0 8 0 nil]

Character code properties are not shown: customize what to show

There are text properties here:
  auto-composed        t
  composition          [Show]
  fontified            t
---->8---->8----

So I guess this is the font issue, that Emacs is not able to figure out
which font to use. For the moment, I added that LISP code in my .emacs,
but is this the proper fix for this issue ? Or, I've to change something
in fonts.conf or any such font-related configuration, hmmm..?

Okay, I know how to use gdb, but how do I know if shaping is working or
not, hmm...?

Hmmm, it seems that your FreeSans.ttf is old.  At least, my
FreeSans.ttf (Version 1.79 of date 16-5-2007) displays that
text correctly.

For Devanagari, by default, Emacs uses an OpenType font that
supports the script `deva' and has feature `rphf'.  If
multiple fonts match that spec, Emacs selects one
arbitrarily.  Perhaps, we must implement a way to reflect
the preference of underlying font-backend.

Are you using FreeSans.ttf from repositories, hmm..? The version of
GNU freefont[1], I'm using is 20080323, released on 24-Mar-2008. BtW, 
I'm using freefont-ttf. And they've made no releases in 2007.

And on hexdump -C FreeSans.ttf, I got following version, I hope thats
the correct version:

Version: $Revision: 1.136$

So, are there any issues with new version of freefont ?

Ummm, then perhaps, some version after 1.79 instroduced a
bug, or my version is the one hacked by some other person.

I don't know.

        This still does not work for me. When I type in "श्रिवास्तव",
 the composition is not happening (the 'sri' should compose into a
 single character, and the 'st' should compose together as well -- what
 I get is the 'स्' character next to 'त', and they should be joined).

        I think back when using the non-free CDAC fonts I could get it
 to work, but I no longer have those fonts on my machine.

Strange.  It works for me.  Attached is the image of Emacs
display.  Is it correct?

        Yes, the figure shows a correctly composed version of my
 name. Well, this is good to know -- this means that the display issue
 is a matter of correctly selecting a font, and that Emacs itself is
 able to do the right thing. Now, if only I could replicate your set up

Please show me the results of:

% m17n-config --version
% libotf-config --version

Or, if you don't have those commands,

% pkg-config --modversion m17n-flt
% pkg-config --modversion libotf

Incidentally, the version of libm17n in debian is only 1.3.4 (I assume
you've compiled a newer version from source), which seems kind of old...

They are the latest version.  Ummm, I don't understand why
Emacs doesn't render Devanagari correctly in your
environment.

When Emacs stops at Ffont_shape_text, please use n(ext)
command to step one line by one, and check where the
function return.

In typing the text like "शुक्ल", I get this bug.

Following is the URL of screenshot of what I'm getting currently:
http://flickr.com/photos/wahjava/2525377097/

An earlier version of Emacs CVS used to render that correctly, as
shown in the following URL of screenshot:
http://flickr.com/photos/wahjava/2488290981/

I'm currently running emacs-cvs (checked-out an hour ago) port, in
Gentoo GNU/Linux :) .
