• Performance of Control+Space.
• New Control+Space GUI window.
• IBus indicator can work without ibus-daemon on gnome-shell to handle XKB only.

Previously ibus-daemon handles the trigger key, Control+Space, and some of the performance problems were happened when input method engines are switched. Now the ibus status icon on panel handles Control+Space and I hope the performance issue was fixed.

Previously the trigger key switches a previous ibus engine and next engine. Now the trigger key behaves to switch multiple engines likes Alt+Tab. If you use Control+Shift+Space, the reverse switching is called. The following is the new window with ibus GTK:

The following is the new window with ibus-gnome3 on gnome-shell:

Requirements:

# yum install ibus ibus-gnome3 gnome-shell gjs
# rpm -q ibus gnome-shell gjs
ibus-1.4.99.20120203-3.fc17.x86_64
gnome-shell-3.3.5-1.fc17.x86_64
gjs-1.31.10-1.fc17.x86_64

Currently we use the devel branch with ibus and ibus-gjs git and when the upstream is updated, I will move the devel branch to master.

ibus-gnome3-1.4.0-17 is now available in Fedora 16 or later.

# yum install ibus ibus-gnome3
% rpm -q ibus
ibus-1.4.0-17.fc16.x86_64

It would enhances the gnome-shell lookup window.

# yum install --enablerepo=updates-testing ibus ibus-gnome3
% rpm -q ibus
ibus-1.4.0-14.fc16.x86_64

This update enhances the shell menu.

Now menu icons on ibus icon menu use the prefix of language names for XKB keymaps and multi-byte special chars for input methods and have numeric suffix if the icon strings are duplicated. (e.g. 中2 and en2)
The ibus shell menu also deletes the item of quit, restart, ibus-setup to follow the UI spec since the indicator will persist for XKB keymaps even if ibus is not running. We’d like to integarte ibus setup into gnome-control-center.
Also this update adds the IM engine’s setup button on ibus-setup.

The feature is upstreamed in ibus HEAD.
We also would like to integrate this function into gnome-control-center.

# yum install --enablerepo=updates-testing ibus ibus-gnome3
% rpm -q ibus
ibus-1.4.0-5.fc16.x86_64

The development ibus-gjs is avaialable here.
1. Get the current keyboard layout when no variant.
ibus could not get the current keyboard layout when the layout has no variant. e.g. ‘us’ layout.
The patch was integrated.

2. An error when XKB feature is disabled.
Fedora enables the XKB feature but this problem is reported by the other platforms.
The patch was integrated.

3. Cannot open ibus panel icon menu in gnome-shell 3.2.1.
I had added a workaround not to move the input focus with ibus status icon in Fedora 15 but it does not work in Fedora 16 and the workaround caused an up compatible issue in gnome-shell 3.2.1.
The patch was integrated.

4. IM engine’s menu items are not selectable on ibus panel icon meenu.
IME menu items cannot be selected because of no focus in gnome-shell 3.2.x because of the F15 workaround.
The patch was integrated.

If I’m not mistaken, you’re the author of this patch for mousepad: http://code.google.com/p/ibus/issues/detail?id=1192
First off, thank you very much for fixing this annoying bug that has vexed me for months!
Now, the only problem is that the same bug still exists for the TAB key, as in TAB key strokes are not recognized with ibus running, but work if I kill ibus.
Sadly, I couldn’t really tell how you fixed the enter key, so I couldn’t reproduce a fix for TAB either.
Maybe your could help me? This problem just seems way too small to open up yet another bug report, so I hope you can help me.

お願いします!

I checked the source code and the similar fix also needs to be applied for TAB key.
The following is the all the fix of Enter and TAB keys:

There are two points to enable ibus-gnome3 with gnome-shell.

#1 Checking the versions
After you install ibus-gnome3 (yum install ibus-gnome3), you will notice /usr/share/gnome-shell/extensions/ibus-indicator@example.com/metadata.json is installed. That file provides the supported versions of gnome-shell and gjs.

# yum install gnome-shell gjs
# rpm -q gnome-shell gjs
gnome-shell-3.1.92-1.fc16.x86_64
gjs-1.29.18-1.fc16.x86_64
# yum install --enablerepo=updates-testing ibus ibus-gnome3
# rpm -q ibus-gnome3
ibus-gnome3-1.4.0-2.fc16.x86_64
# cat /usr/share/gnome-shell/extensions/ibus-indicator@example.com/metadata.json
{"shell-version": ["3.1.92"],
 "js-version": ["1.29.18"],
 "uuid": "ibus-indicator@example.com",
 "name": "Input-Method Status Indicator",
 "description": "Add a system status menu for input-methods using IBus",
 "url": "https://github.com/fujiwarat/ibus-gjs"
}

The example shows metadata.json file has the two keys ‘shell-version’ and ‘js-version’ and ‘shell-version’ is ’3.1.92′ and ‘js-version’ is ’1.29.18′.
The versions are matched with the versions of gnome-shell and gjs.
If the versions are different, ibus-gnome3 won’t be enabled with gnome-shell. [1]

#2 Enable dconf key
Unfortunately all shell extensions are disabled by default in GNOME 3.2 so you need to enable the dconf key by manual.

% gsettings get org.gnome.shell enabled-extensions 
[]
% gsettings set org.gnome.shell enabled-extensions "['ibus-indicator@example.com']"
% gsettings get org.gnome.shell enabled-extensions 
['ibus-indicator@example.com']

Now you can enable ibus-gnome3 with gnome-shell in Fedora 16. [2]

% gnome-shell --replace

If you cannot enable ibus-gnome3 but no errors on terminal, probably the follwing debug option might be useful for you

% env GJS_DEBUG_OUTPUT=stderr  gnome-shell --replace

Note: gnome-shell 3.2.0 and gjs 1.30.0 will be available soon and I also will update ibus-gnome3 with metadata.json file.

[1] Actually gnome-shell compares the versions with /usr/share/gnome-shell/js/misc/config.js and the checking script is versionCheck() in /usr/share/gnome-shell/js/ui/extensionSystem.js
[2] If you’d like to run gnome-shell by manual, compiz-gnome can shows the ‘Classic GNOME with Compiz’ on GDM login screen.

I also added some links in https://live.gnome.org/GnomeShell/Design/Guidelines/SystemStatus/InputLanguage

# yum install --enablerepo=updates-testing ibus ibus-gnome3
# rpm -q ibus-gnome3
ibus-gnome3-1.3.99.20110419-11.fc15.x86_64

It also includes a patch from ueno-san, which can provide a separated package as ibus-gnome3.

The package ibus-gnome3 is a test package and I have to discuss with upstream whether the embedded function or the separated module is better.
Probably I have to fix vertical-horizontal window and have a few RFEs about enabling the clicking commit on the lookup window and adding a handle widget (likes Gtk.paint_handle).

I think it can work with the upstream ibus but I’m also adding some features in my gjs brach:
https://github.com/fujiwarat/ibus/tree/gjs
Actually they are integrated in Fedora 16 and 15.
