Subject: 24.0.94; Arabic character composition
Date: Fri, 23 Mar 2012 16:44:01 +0100

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

Although Emacs 24 has bidi support (yay!), character composition for Arabic
does not work for me on OS X. (In the Arabic script, each character has
different forms depending on its position in the word: beginning, middle or
end. These shapes should be selected automatically by the software, but
they are not.)

On Linux, Emacs needs to be compiled with libotf in order to provide the
necessary character composition, which then works perfectly.

Unless you build Emacs with a library that supports Arabic shaping,
you won't be able to have it.  Does OS X offer such a library?

Can't libotf be compiled on OS X?

I don't know, but I suspect it does, because Arabic text is displayed
correctly in e.g. TextEdit. (Though interestingly, neither LibreOffice nor
MS Word do...)

I haven't tried, but since it's part of both Fink and MacPorts, I suspect
it can.

I can try compiling libotf and then Emacs 24 and see if it works, but it'll
be a few days (perhaps even more) before I have an opportunity (and the
time...) to do so. (OTOH, since libotf isn't part of OS X, it may not be
preferable for Emacs to use it on OS X, especially if there is a native
library.)

Anyway, just let me know if I can help.

Well, maybe you can find out what that libraries are and how to link
against them, then we could include the necessary instructions in
Emacs.

If you try that, please be sure to build all the libraries mentioned
in INSTALL under "Complex Text Layout support libraries".

I don't have access to OS X, so if you could build libotf and the
other libraries mentioned in INSTALL and see if that gets you Arabic
shaping, that'd be nice.  Thanks in advance.

Since I'm not an Apple developer, I'm not really sure where to look for
such information. From what I've found through Google, it seems that the
relevant library is simply CoreText, but I may completely misunderstand how
OS X libraries work...

I've tried, but haven't been successful... m17n-db can be installed, though
it requires downloading the charmaps and installing GNU/gettext because the
program msgfmt isn't part of OS X. (It's part of GNU/gettext but not of the
gettext that comes with OS X, it seems.)

Then, however, configuring m17n-lib failed with the following message:

autoreconf: running: aclocal --force -I m4
autoreconf: configure.ac: tracing
autoreconf: configure.ac: not using Libtool
autoreconf: running: /usr/local/Cellar/autoconf/2.68/bin/autoconf --force
configure.ac:52: error: possibly undefined macro: AC_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /usr/local/Cellar/autoconf/2.68/bin/autoconf failed with exit status: 1

Since I have no idea what this is about, I stopped my attempts at
installation.

The NS port doesn't support text shaping.  The Mac port, which used to
support text shaping only for left-to-right, now also supports for
right-to-left:

  http://lists.gnu.org/archive/html/emacs-devel/2012-04/msg00018.html

I'd appreciate it if you could accept its experimental/hackers-only
status and try it, because its right-to-left text shaping code is very
new and not fully tested.

I'd be happy to try it, but when I open the Emacs.app included in the mac/
folder, I get the following error:

joost <at> pc201:~/Desktop/emacs-24.0.95-mac-2.91/mac $ open Emacs.app/
LSOpenURLsWithRole() failed with error -10810 for the file /Users/joost/Desktop/emacs-24.0.95-mac-2.91/mac/Emacs.app.

(Same thing happens if I move Emacs.app to /Applications.)

It seems that you don't have libtool.

By the way, as someone else wrote, the current OS X port
code doesn't support text shaping, which means, even if you
successfully installed m17n-lib and libotf, Emacs can't use
it.

Well, XCode (which I have installed) does have a program called libtool,
but it's not GNU libtool.

Ah ok... Thanks for pointing that out. I won't make any further attempts,
then.

Hi, does anyone know if this bug was resolved? I assume if it worked in

In the seven or eight years since this bug report was made, we
switched over to the mac port font backend.

It might still be an issue on GNUstep, though. I think it still uses
nsfont.m.

It looks to me like this works on macOS now.  At least the Arabic
characters compose differently depending on where they are in the
word. Admittedly, my knowledge here is superficial at best, having done
only a brief foray into learning beginner Persian.

So, I can't say for sure if they compose correctly, just that they
compose differently.

Since that was written, harfbuzz was enabled by default.  And wouldn't
that library have good support for this anyhow?

I'm not a GNUstep user so I can't easily test this.

But would the recent harfbuzz support (enabled by default on GNUstep
too, I assume) fix this?  Do you know, Eli?

It should (assuming the GNUstep build supports HarfBuzz).

As I understand it Harfbuzz is not supported on the NS port at all. I
know that Yamamoto Mitsuharu wrote a proof of concept, but I don’t
believe it was ever finished.

It is for the mac-ct font backend, and doesn't work on GNUstep.

What are the problems that prevent getting HarfBuzz to work in the
GNUstep port?  I think we want all the major supported platforms to be
able to build with HarfBuzz, since many modern features related to
sophisticated text shaping and display to be developed for Emacs will
be based on HarfBuzz facilities.

I’m not aware of any fundamental problems, I think someone just needs
to write the code.

Most of the code is already in hbfont.c, you just need the

supported on all major platforms.

Thanks.
