ibus-mozc doesn't work when switching from Russian layout

[WGH-]

I have three layouts in ibus: ['xkb:us::eng', 'mozc-jp', 'xkb:ru::rus'].

mozc only works correctly when switching from English. If you switch from Russian layout to mozc, it will type Cyrillic letters instead of functioning properly.

% ibus version
IBus 1.5.14

It happens on at least mozc-2.16.2037.102 and mozc-2.20.2677.102.

FWIW, anthy doesn't suffer from this.

This is caused by layout option in /usr/share/ibus/component/mozc.xml. So basically if you change layout from default to jp, it works correctly. Anthy uses jp as well, which explains why Anthy doesn't have this issue.

Ping. Any reasons why default should be used instead of jp?

Hi, sorry for too late reply,

The default basically works well unless the user uses multiple keyboard layouts like this issue.
If we use jp here, people who use the us layout will have an inconsistent layout problem for example.

As you mentioned, you can specify the keyboard layout by modifying mozc.xml if you have the root permission.

Since 9ba59b6, the setting is moved to your home directory.
So you do not need the root permission.

Hi, I have the same problem with an additional issue: I use Dvorak.

If I configure Mozc either as

$ cat $HOME/.config/mozc/ibus_config.textproto           
# `ibus write-cache; ibus restart` might be necessary to apply changes.
engines {
  name : "mozc-jp"
  longname : "Mozc"
  layout : "us"
  layout_variant : "dvorak"
}
active_on_launch: False

or

$ cat $HOME/.config/mozc/ibus_config.textproto           
# `ibus write-cache; ibus restart` might be necessary to apply changes.
engines {
  name : "mozc-jp"
  longname : "Mozc"
  layout : "jp"
  layout_variant : "dvorak"
}
active_on_launch: False

the input layout (before conversion to Japanese) is always QWERTY.

If I set

$ cat $HOME/.config/mozc/ibus_config.textproto           
# `ibus write-cache; ibus restart` might be necessary to apply changes.
engines {
  name : "mozc-jp"
  longname : "Mozc"
  layout : "default"
  layout_variant : ""
}
active_on_launch: False

then the input layout is the last used one: either Dvorak or Russian.

Any hint how to make it work with Dvorak?

Hi, would you check the output of /usr/lib/ibus-mozc/ibus-engine-mozc --xml, and check if the output contains the <layout_variant> tag?

Here's my output for example:

<engines>
<engine>
  <description>Mozc (Japanese Input Method)</description>
  <language>ja</language>
  <icon>/usr/share/ibus-mozc/product_icon.png</icon>
  <rank>80</rank>
  <icon_prop_key>InputMode</icon_prop_key>
  <symbol>&#x3042;</symbol>
  <setup>/usr/lib/mozc/mozc_tool --mode=config_dialog</setup>
  <name>mozc-jp</name>
  <longname>Mozc</longname>
  <layout>default</layout>
  <layout_variant></layout_variant>
  <layout_option></layout_option>
</engine>
</engines>

if your output doesn't contain <layout_variant>, your Mozc version doesn't support it yet.
In that case, you might want to do either of

1. Update the Mozc version.
2. Modify /usr/share/ibus/component/mozc.xml as a workaround.

The file locations are possibly different if your distribution is not Debian or Ubuntu.

At the moment, I have the following settings:
/usr/lib/mozc/mozc_tool --help shows ver. 2.26.4538.102
Built on Arch Linux from the commit 5e7fdb7.

cat $HOME/.config/mozc/ibus_config.textproto

# `ibus write-cache; ibus restart` might be necessary to apply changes.
engines {
  name : "mozc-jp"
  longname : "Mozc"
  layout : "jp"
  layout_variant : "dvorak"
  rank : 0
}
active_on_launch: False

/usr/lib/ibus-mozc/ibus-engine-mozc --xml

<engines>
<engine>
  <description>Mozc (Japanese Input Method)</description>
  <language>ja</language>
  <icon>/usr/share/ibus-mozc/product_icon.png</icon>
  <rank>0</rank>
  <icon_prop_key>InputMode</icon_prop_key>
  <symbol>&#x3042;</symbol>
  <setup>/usr/lib/mozc/mozc_tool --mode=config_dialog</setup>
  <name>mozc-jp</name>
  <longname>Mozc</longname>
  <layout>jp</layout>
  <layout_variant>dvorak</layout_variant>
  <layout_option></layout_option>
</engine>
</engines>

Which somehow results in:

• Mozc Direct input: QWERTY instead of Dvorak.
• Mozc Hiragana: QWERTY instead of Dvorak.
