xkb greek polytonic: cannot write psili and dasia after upgrade to breezy

How do you write the other Greek Polytonic accents in GNOME?

See
http://bugzilla.gnome.org/show_bug.cgi?id=167940
and if you speak Greek, see
http://www.livejournal.com/users/simos74/32918.html

(In reply to comment #1)

I use X Input Method. The effect is the descripted above.

Happened to me too on SuSE 9.3 using KDE, using polytonic greek layout typing shift+semicolon prints nothing, whereas everything else works according to the xkb symbol file pc/el. Maybe LC_CTYPE has something to do with it?

setxkbmap -model pc104 -layout us,el -variant ,polytonic -option grp:caps_toggle
LANG=en_US.UTF-8

I verify that this bug exists.

What happens is that Xorg is able to send the mentioned characters, however, somewhere in both GTK+ and QT applications cannot receive them.

To verify, run an X application such as "xterm" (is there an old-style X editor around?).

Try
$ xterm -font "-bitstream-dejavu sans mono-medium-r-normal--0-0-0-0-c-0-iso10646-1"

Then, switch the keyboard to Greek Polytonic:
άὰἁἀᾷᾶὰἇῢ

I cannot figure out why some characters are excluded and other are not.

This issue is not directly related to the upstream bug report in GTK+.

Some more results:

The compose file in Breezy (probably Dapper) contains "incompatible" (???) compose sequences for polytonic letters that have diacritical marks. Those "incompatible" compose sequences do not produce any characters, so as is, it is not possible to produce daseia, psili and possibly others. Not possible, either in GTK+, QT, old X apps.

If someone fixes the Compose file*, then in QT applications it is possible to type all those characters. In GTK+ applications I was not able to type them, though it is possible that some settings where cached; I did not restart my session.

Due to the upstream GTK+ bug report, for GTK+ applications one needs to set the Input Method to the X Input Method in order to use the fixed Compose file.

To "fix" the compose file, replace the existing Greek polytonic compose sequences in /usr/share/X11/locale/en_US.UTF-8/Compose
with those generated by
http://hal.csd.auth.gr/~vvas/i18n/xkb/polytonic-compose.pl

It seems to be a bug in the greek layout file in /etc/X11/xkb/symbols/gr. Following the hint in http://www.jw-stumpel.nl/stestu.html#T6.5.3 I changed the lines
key <AC10> { [ dead_acute, dead_horn ] };
key <AC11> { [ dead_grave, dead_ogonek ] };
 to
key <AC10> { [ dead_acute, U0313 ] };
key <AC11> { [ dead_grave, U0314 ] };
and writing psili and dasia is working again.

Marking as Confirmed to match upstream bug, assigning to team since I'm not working on that and we will likely wait for upstream

libx11 (2:1.0.3-0ubuntu5) feisty; urgency=low

    console-setup and debian-installer; LP: #21637):
    - 019_greek_polytonic_Compose.diff (numbered 016 in Debian): Add compose

I think this should be a lot better following the libx11 and xkeyboard-config merges above in Feisty, but I don't know enough about GTK to know if it still needs to be modified. Can anyone check, perhaps once Herd 1 is out?

dead_grave doesn't seem to produce grave's properly. Used with shift it does produce another dead-keys character as expected, and it does produce a grave if used in xterm, but not in gtk apps.

A patch has been applied upstream which should solve these issues.

Patch is described at
http://blogs.gnome.org/simos/2008/03/05/testing-the-updated-im-support-in-gtk/

Two new keysyms, dead_psili and dead_dasia have been added to Xorg.
xkeyboard-config has been updated with dead_psili and dead_dasia.
GTK+ has been updated to dead_psili and dead_dasia (on Trunk).

This means that Hardy should be able to type Greek polytonic (when using XIM).
The GTK+ patch will probably make it in the next version of Ubuntu.

Fix has been commited in GTK+ (trunk)

There might still be some problems left in hardy. I upgraded from gutsy, where I was able to write polytonic Greek with XIM after I replaced the Compose file with a modified one. After upgrading to hardy (beta -- now up to date as of 2008-04-20) I found that I was not able to type dasia or psili anymore (with XIM, previously shift+ä and shift+ö + plus letter produced the breathings -- ä and ö being the two keys left from L in my keyboard) -- pressing them did not produce anything.

Then I modified /usr/share/X11/xkb/symbols/gr file, keys AC10 and AC11 to

  key <AC10> { [ dead_acute, dead_dasia ] }; // ´ ̓
  key <AC11> { [ dead_grave, dead_psili ] }; // `

According to a freedesktop.org bug (unfortunately I don't have the link right here, if I recall, Simos Xenitellis who also subscribes to this bug, commented/opened it.

This didn't change anything.

Then I changed dead_dasia to U0313 and dead_psili to U0314 -- Now I am able to type the breathing marks, but they don't combine with other accents -- acute is just written over the breathing, for instance.

I seems that the fixes that are in hardy are not complete. What has changed since gutsy, where I had perfect output, just after modifying the Compose file?

Ok. I should have checked my old modified Compose file. It seems that hardy has

/usr/share/X11/xkb/symbols/gr:

key <AC10> { [ dead_acute, dead_horn ] };
key <AC11> { [ dead_grave, dead_ogonek ] };

which I changed to

key <AC10> { [ dead_acute, U0313 ] };
key <AC11> { [ dead_grave, U0314 ] };

and in /usr/share/locale/en_US.UTF-8

has U10000313's and 010000314's instead of U0313 or U0314. I changed U1000313's and U1000314 to U0314 and got polytonic input working correctly. Let's see how the upgrades in x.org ja gtk have progressed in hardy+1

the new version has been uploaded to intrepid now

Sorry, but I not english speaker:
I solved in this way:
I didn't modificated neither Compose file neither gr file.
I had spanishlayout and installed greek polytonic, with the GUI of Gnome.
I saw the composer combination didn't work in greek
I correct /etc/environment with the line export GTK_IM_MODULE=xim
export QT_IM_MODULE=xim
I copy Composer en_US.UTF-8 to .XCompose (this archive seem to have the combination Composer of the predefinide language)
  cp /usr/share/X11/locale/en_US.UTF-8/Compose ~/.XCompose
and works.
The changes of gr file (U0313 and U0314) are not usefull, because the introduce a combinated acent, not show the real ancient greek character.
about the horrible definition of <dead_ogonek> and <dead_horn>, I tried to changed modificating (keysymdef.h). But the <dead_dasia> and <dead_psili> i think are wrong.
Please, If someboy understand me, rewrite this post correctly
