IBus(Intelligent Input Bus) is an input method(IM) framework that uses a bus-like architecture. It's widely used in the Linux desktop world and is integrated in desktop environments like Gnome. It allows for different plugins to be installed for input in different languages, this modular design + compatibility with XKB and desktop environments makes ibus the preferred choice for people typing in CJK(Chinese Japanese Korean), Vietnamese, Thai and other languages that require specific tools not found in standard XKB.

Installation

app-i18n/ibus USE flags
+X Adds X11 support
appindicator Builtin support for notifications using the libindicate or libappindicator plugin
+emoji Enables emoji support
gtk2 Enables GTK-2 input method module
+gtk3 Enables GTK-3 input method module
gtk4 Enables GTK-4 input method module
+gui Enables support for a graphical user interface
+introspection Adds support for GObject based introspection
nls Adds Native Language Support(using gettextGNU locale utilities)
+python Adds optional support/bindings for the Python programming language
test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
+unicode Enables support for Unicode choice
vala Enables bindings for dev-lang/vala
wayland Enables dev-libs/wayland backend

Installing ibus is as simple as:

root # emerge ibus

once ibus is installed, you can use it as is because it is interoperable with XKB, or you can install tables and plugins to add additional language support if needed.

Integrating ibus into your Desktop Environment

Gnome and Gnome-based desktops support ibus out of the box so you don't have to configure anything

For KDE the ibus USE flag needs to be enabled for the following packages:

  1. qtgui
  2. plasma-desktop

For all desktops you are going to need to add the following code to your ~/.xinitrc or ~/.xprofile

   ~/.xprofile or ~/.xinitrc (sh source code)
export XMODIFIERS=@im=ibus
export GTK_IM_MODULE=ibus
export QT_IM_MODULE=ibus
export SDL_IM_MODULE=ibus
export GLFW_IM_MODULE=ibus

ibus-daemon -drx

The environment variables will be read by applications which will enable ibus support, the last line starts the ibus-daemon so that you don't have to start it manually

Using the ibus interfaces

Once ibus is installed, normally there will be 2 ways to interact with it, the ibus CLI and the ibus-setup GUI

IBus CLI

The ibus command provides multiple ways of interacting with ibus, for example:

user $ ibus engine

will list the current active ibus engine

user $ ibus engine libpinyin

will set the current ibus engine to libpinyin

user $ ibus list-engine

will list all available engines for every language category, while the control arguments of

  1. start
  2. restart
  3. exit

will control the state of the ibus daemon

For more information refer to the ibus wiki

IBus GUI

On some desktops such as Gnome where ibus is integrated into the desktop environment, you might get the IBus settings integrated into your settings manager, these settings however are not as full as the ones provided by the official IBus GUI settings manager, ibus-setup

To open it, run the command ibus-setup and a window like this should appear:

Ibus-setup-default-screen.png

Under the General tab you can find common settings such as the IM switching keybing and font settings

Under the Input Method tab you can find your current input methods. On the side panels you can add, remove, access the settings or information about a given input method. Here is an example image:

Ibus-setup-input-method-screen.png

When compiled with the default USE flags, ibus provides emoji input and settings under the Emoji tab, Example image below:

Ibus-setup-emoji-screen.png

Finally in the Advanced tab you can find settings that allow you to change the theme of the IBus GUI, as well as settings on whether to use the system keyboard layout, and whether to share the input method among all applications:

   Important

If you depend on running a custom keyboard layout in XKB that isn't available by default in both XKB and ibus, you are going to need to use both systems for input. To do that make sure that the settings Use system keyboard layout and Share the same input method among all applications are enabled, otherwise you will notice how your layout changing shortcut in XKB, doesn't switch to your languages set in your XKB settings

IBus plugins in Funtoo

Funtoo provides multiple packages for different language support in IBus, for more information please open the separate wiki pages listed below:

  1. Chinese
  2. Korean
  3. Vietnamese
  4. Miscellaneous input methods
