Description Maciej Katafiasz 2006-09-03 16:00:45 UTC
UIM 1.2.0 has broken the Compose key operation, which used to work flawlessly in
1.1.1 and earlier. With 1.2.x, only very few combinations work (such as Compose
+ a + e (æ) or Compose + / + o (ø), but NOT Compose + o + /), and the vast
majority has no effect. They're not regarded as invalid (it doesn't beep), just
eaten silently, and actual invalid combos (such as C + h + y) result in the last
character (here "y") input being inserted instead of a beep.

This is a showstopper for anyone relying on Compose operation (like me, I am
Polish but live in Denmark, and use Compose to do 100% of my Danish writing);
setting the severity to critical because not many people know or use Compose,
but otherwise it's a blocker.

The version of UIM is 1.2.0 / 1.2.1, official releases compiled from source on
Ubuntu 6.06 Dapper, with the following config:

   Anthy           : no
   Canna           : no
   Mana            : no
   PRIME           : no
   m17n-lib        : no
   SCIM            : no
   Gtk+            : yes
   Gnome Applet    : yes
   Qt              : no
   Qt immodule     : no
   FEP             : no
   Emacs           : yes
   XIM             : yes
   Pref            : yes
   DICT            : no
   EB              : yes
   libedit         : no
   Default toolkit : gtk

prefix=/usr/ (it was built into a .deb with checkinstall)

1.1.1 from official sources compiled with the exact same config works like a
charm. It occurs at least for GTK+, can't test it for Qt as I didn't build it.
As a sidenote, the very same thing occurs when you select XIM as input method
from GTK+'s context menu without an input method actually running.
Comment 1 Etsushi Kato 2006-09-03 21:00:37 UTC
Thanks for the report.

From uim 1.2.0, our GTK+ and Qt input modules use X11's compose sequence table
in backend compose input instead of gtk+ internal one, as requested in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=377808.  The reporter said
GTK+'s internal table is not sufficient for user of traditional X11.

If you use da_DK.UTF-8 locale, $prefix/share/X11/locale/en_US.UTF-8/Compose is
used as a compose table.  And it doesn't seems to have "<Multi_key> <o> <slash>"
sequence as ø letter.  That the problem.

One way to solve the problem is copy
$prefix/share/X11/locale/en_US.UTF-8/Compose as $HOME/.XCompose, and
add your required compose sequences as follows.

<Multi_key> <o> <slash> : "ø" U00F8


Could you tell me which sequences have no effent (you said the vast majority)
with uim-1.2.1?

Cheers,

See message in
http://lists.freedesktop.org/archives/uim/2006-September/001532.html and
http://lists.freedesktop.org/archives/uim/2006-September/001533.html.  Maybe we
should merge compose table of gtkimcontextsimple and xorg's UTF-8 compose file.
Comment 4 Maciej Katafiasz 2006-10-06 16:19:29 UTC
Okay, it seems that I was just a particularly good target, having used GTK+
Danish sequences. Below is the content of my ~/.XCompose, until the two are
merged. This is not by any means complete, just the sequences I noticed the lack
of immediately:

<Multi_key> <O> <slash>          	: "Ø"   U00D8 # LATIN CAPITAL LETTER O WITH STROKE
<Multi_key> <O> <KP_Divide>      	: "Ø"   U00D8 # LATIN CAPITAL LETTER O WITH STROKE
<Multi_key> <o> <slash>          	: "ø"   U00F8 # LATIN SMALL LETTER O WITH STROKE
<Multi_key> <o> <KP_Divide>      	: "ø"   U00F8 # LATIN SMALL LETTER O WITH STROKE
<Multi_key> <A> <A>              	: "Å"   U00C5 # LATIN CAPITAL LETTER A WITH
RING ABOVE
<Multi_key> <A> <*>              	: "Å"   U00C5 # LATIN CAPITAL LETTER A WITH
RING ABOVE
<Multi_key> <*> <A>              	: "Å"   U00C5 # LATIN CAPITAL LETTER A WITH
RING ABOVE
<Multi_key> <a> <a>              	: "å"   U00E5 # LATIN SMALL LETTER A WITH RING
ABOVE
<Multi_key> <a> <*>              	: "å"   U00E5 # LATIN SMALL LETTER A WITH RING
ABOVE
<Multi_key> <*> <a>              	: "å"   U00E5 # LATIN SMALL LETTER A WITH RING
ABOVE
<Multi_key> <e> <equal>          	: "€"   EuroSign # EURO SIGN
<Multi_key> <equal> <e>          	: "€"   EuroSign # EURO SIGN
<Multi_key> <T> <M> 			: "™"   U2122 # TRADE MARK SIGN


However, there's another bug. ~/.XCompose *replaces*, and not augments normal
systemwide compose tables, so if you add ~/.XCompose, you lose all previously
defined sequences. As I can't find any way to say "include file", I needed to
copy verbatim the whole $prefix/share/X11/locale/en_US.UTF-8/Compose and paste
it into my ~/.XCompose. If anyone can confirm that behaviour, it needs reporting
in X.org.
Comment 5 Etsushi Kato 2006-10-06 23:03:00 UTC
Thanks for the list of sequences.  Since I haven't started to investigate the
diff between X11's Compose and GTK+ yet, it will help.

X.org's Compose surely supports "include file" system.
Please try to add following line in ~/.XCompose that contains only your specific
sequences.

include "/usr/share/X11/locale/en_US.UTF-8/Compose"
Comment 6 Mikael Magnusson 2007-06-19 20:50:46 UTC
hooray for finding old bugs on google, just wanted to mention you can use this to include the default compose map easily:
include "%L"
Comment 7 Marcin 'Qrczak' Kowalczyk 2007-08-08 04:51:19 UTC
Here is a patch which replaces the compose table in Gtk+ with the table taken from libX11-1.1.1 (excluding characters above U+FFFF which are not supported by UIM). It includes a script to regenerate it.

http://cvs.pld-linux.org/cgi-bin/cvsweb/SOURCES/gtk+2-compose-table.patch.bz2

Although the new table doesn't include e.g. [o/ → ø], leaving only [/o → ø], it's richer in other areas, e.g. [<" → “], [>" → ”], [," → „]. Some diacritics have been disunified: , = cedilla, ; = ogonek. The diacritic is always before the base letter, which leaves room for letter keys to denote some diacritics, e.g. o = ring above.

I propose to let Gtk+ use the same table as X11 by default, to avoid user confusion. Further improvements should be done in both sources.

Thanks for letting us know about the patch.  I think you should add your comment on GTK+'s bugzilla (http://bugzilla.gnome.org/show_bug.cgi?id=88639).
