How I set up ひらがな input on my laptop
I am currently working with Hiragana, Katakana, and, Kanji in some projects, and needed a more reliable way to write than running some romaji through an online translator. So, this post will detail what I did to enable native inputs on my laptop. This guide is specifically for i3wm, because it does not obey system settings for languages and inputs.
Adding font support to Linux
Firstly, we need fonts. Depending on your system, these may already be installed. For Japanese, I only used
vlgothic, so here in the package for it:
sudo apt install fonts-vlgothic
Im not sure if this matters, but I have seen other people do it, so why not be safe?
I am currently running a stock Ubuntu 18.04 base, which means that everything is pre-configured for Gnome. To set language support in Gnome, pull up the settings panel:
# This line fixes some compatibility issues between # Gnome and I3 when launching the settings menu. # I recommend aliasing it. env XDG_CURRENT_DESKTOP=GNOME gnome-control-center
Next, go to Settings > Language and Region > Input Sources, and click on Manage Installed Languages. This will bring up a window where you can select a new language to install. From here, I clicked on Install / Remove Language.
In this list, I just selected the languages I wanted (English and Japanese), and applied my changes. You may be asked to enter your password while installing the new languages. Once installation is complete, log out, and in again.
With the new language support installed, return to the Input Sources settings, and press the
+ button to add a new language. From here, search the language you want (it may be under Other) and select it. For Japanese, select the
Gnome's language settings are now configured. If you are using Gnome (not I3), you can stop here.
Don't get me wrong, I love I3wm, but sometimes it's configurability drives me crazy.
After searching through various forums and wikis looking for an elegant way to switch languages in I3, I found a link to an ArchWiki page at the bottom of a mailing list (I blame Google for not showing this sooner). It turns out that a program called
ibus is exactly what I needed. Here is how to set it up:
mozc from above? If you are not using it, this package may not work. Search for the appropriate
ibus- package for your selected language(s).
# Install ibus-mozc for Japanese (mozc) sudo apt install ibus-mozc
ibus is installed, run the setup script:
From here, set your shortcut to something not used by I3 (I chose
CTRL+Shift+Space, but most people prefer
Alt+Space), and enable the system tray icon.
Now, go to the Input Method settings.
From here, press the
+, and add your language(s).
According to the Wiki page, I needed to add the following to my
# Language support export GTK_IM_MODULE=ibus export XMODIFIERS=@im=ibus export QT_IM_MODULE=ibus ibus-daemon -d -x
It turns out that this causes issues with some browsers, so I actually put this in my
# Language support export GTK_IM_MODULE=xim export XMODIFIERS=@im=ibus export QT_IM_MODULE=xim ibus-daemon -drx
Now, log out and in again to let ibus properly start again, and there should now be a new applet in your bar for language settings.
ibus runs in the background and will show an indication of your selected language upon pressing the keyboard shortcut set in the setup tool. For languages like Japanese, where it's writing systems do not use the English / Latin-based alphabets,
ibus will automatically convert your words as you type (this behavior will be different from language to language).
An example of this is as follows. I want to write the word Computer in Japanese (Katakana to be exact). I would switch to
mozc input, and start typing the romaji word for computer, Pasokon. This will automatically be converted to Hiragana, ぱそこん. Computer is not a word that one would write in Hiragana as far as I know, so Katakana would be a better choice. To convert this word, I just press
Space (This is indicated in the bottom left of my screen by
ibus), and I now have パソコン, the Katakana word for Computer!
