antergos_japaneseIME.md

1. Install using pacman -S or pamac-manager:

adobe-source-han-sans-jp-fonts
mozc
uim-mozc

2. Add to ~/.xprofile, ~/.xinitrc or ~/.xsession:
   Note: uim-toolbar-gtk3-systray displays on Cinnamon but not with GNOME3
   for GNOME3 have to use the floating menu uim-toolbar-gtk3

export GTK_IM_MODULE='uim'
export QT_IM_MODULE='uim'
uim-xim &
uim-toolbar-gtk3-systray &
export XMODIFIERS='@im=uim'

3. Log out/in and test. Default is ctrl+shift to switch input methods.

4. Edit preferences using GUI: uim-pref-gtk

   Group -> Global Settings

   Default input method: Direct # otherwise Mozc (Japanese input) will be default for all new windows
   Enabled input methods: "Mozc" # just Mozc by itself

   Group -> Mozc

   Enabled toolbar buttons: "Input mode", "Mozc tool"
   Default input mode: Hiragana
   Input mode menu items: "Hiragana", "Katakana", "Halfwidth Katakana", "Halfwidth Alphanumeric", "Fullwidth Alphanumeric" # removed "Direct input"

TROUBLESHOOTING

1. Check if environment variables are set correctly. Using fish:

echo $XMODIFIERS
echo $GTK_IM_MODULE
echo $QT_IM_MODULE

2. Manually set environment variables. Using fish:

set -x XMODIFIERS @im=uim
set -x GTK_IM_MODULE uim
set -x QT_IM_MODULE uim

NOTES

• uim-toolbar-gtk3-systray doesn't seem to work with GNOME3 (doesn't appear in tray or anywhere at all)
  (however uim-toolbar-gtk and uim-toolbar-gtk3 do bring up a floating menu)

• uim-toolbar-gtk3-systray DOES work with Cinnamon, however the systray icon is squashed
