Ibus linux что это

Обновлено: 03.07.2024

Интеллектуальные входная шина ( IBus , объявленный как IBUS) представляет собой метод ввода (IM) , основу для многоязычного входа в Unix-подобные операционные системах. Название «Автобус» происходит от его архитектуры, напоминающей автобус .

СОДЕРЖАНИЕ

Основные цели проекта IBus:

  • Обеспечение полнофункциональных и удобных пользовательских интерфейсов для методов ввода
  • Использование мер аутентификации для повышения безопасности
  • Предоставление универсального интерфейса и библиотеки для разработчиков методов ввода
  • Соответствие потребностям пользователей из разных регионов и обычаев

Мотивация

С тех пор были начаты успешные проекты, такие как IM-BUS (возглавляемый Джеймсом Су ) и SCIM-2 (возглавляемый Чжэн Ху ). Однако оба проекта приостановлены. Поэтому Хуанг Пэн из Red Hat основал проект IBus, чтобы доказать идею IM-BUS, используя Python, D-Bus и GLib, а не реализуя функции, рекомендованные форумом CJK OSS. Несмотря на это, IBus уже получил признание сообщества, а FreeBSD и многие дистрибутивы Linux, такие как Fedora и Ubuntu, уже имеют IBus в своих репозиториях пакетов. IBus стал новой структурой метода ввода по умолчанию в Fedora 11 и заменил SCIM в Ubuntu 9.10.

Архитектура

IBus разработан на C и Python , что позволяет избежать проблемы перехода C ++ ABI в SCIM <1.4.14.

IBus предоставляет большую часть своих функций через службы. Есть три вида услуг:

  • Механизм метода ввода (IME): фактический метод ввода
  • Конфигурация: обрабатывает конфигурацию для IBus и других служб, таких как IME.
  • Панель: пользовательский интерфейс, например языковая панель и таблица выбора кандидатов.

Он реализует протокол XIM и имеет модули методов ввода GTK и Qt .

Функции

  • Загрузка и разгрузка двигателя по запросу
  • Поддержка области уведомлений на панели задач
  • Совместимость с XKB
  • Немедленно применяет изменения конфигурации
  • Предоставляет привязки C и Python

Доступные плагины и движки методов ввода

ibus-m17n

ibus-m17n - это IME, использующий методы ввода и соответствующие значки из базы данных m17n. В отличие от ibus-table, который поддерживает простые таблицы, методы ввода m17n также поддерживают состояния, метки которых отображаются на панели IBus (языковая панель). Методы ввода M17n также поддерживают окружающий текст, следовательно, с помощью ibus-m17n поддерживаются такие языки, как тайский, и IM, такие как простой чжуинь , для которых требуется эта функция.

ibus-стол

ibus-table, разработанный Yu Wei Yu, представляет собой IME, который загружает таблицы методов ввода, которые не требуют сложной логики для выбора слов. Таким образом поддерживаются многие методы ввода на китайском языке на основе структуры, такие как Cangjie и Wubi .

Fcitx is a lightweight input method framework aimed at providing environment independent language support for Linux. It supports a lot of different languages and also provides many useful non-CJK features.

Installation

Input method engines

Fcitx provides built-in input methods for Chinese Pinyin and table-based input (for example Wubi).

Depending on the language you wish to type, other input method engines are available:

Chinese

  • fcitx-baidupinyinAUR , fcitx wrapper for Baidu Pinyin IM engine.
  • fcitx-chewing is a popular Zhuyin input engine for Traditional Chinese based on libchewing .
  • fcitx-cloudpinyin uses internet sources to provide input candidates. The selected cloud result will be added to local dictionary. It support all fcitx pinyin input method except fcitx-rime .
  • fcitx-googlepinyin , Googlepinyin wrapper for fcitx.
  • fcitx-libpinyin , based on libpinyin . It has a better algorithm than fcitx-sunpinyin .
  • fcitx-rime , based on schemas from the Rime IME project.
  • fcitx-sogoupinyinAUR , Sogou input method supporting Jianpin, fuzzy sound, cloud input, English input, and mixed skin.
  • fcitx-sunpinyin , based on sunpinyin . It strikes a good balance between speed and accuracy.

Japanese

  • fcitx-anthy , a popular Japanese input engine. However, it is not actively developed anymore.
  • fcitx-mozc , based on Mozc, the Open Source Edition of Google Japanese Input.
  • fcitx-kkc , a Japanese Kana Kanji input engine, based on libkkc .
  • fcitx-skk , a Japanese Kana Kanji input engine, based on libskk .

Other languages

  • fcitx-hangul , for typing Korean hangul, based on libhangul .
  • fcitx-m17n , for other languages provided by M17n.
  • fcitx-sayura , for typing Sinhalese.
  • fcitx-unikey , for typing Vietnamese characters.

Input method module

To obtain a better experience in Qt programs, install the fcitx-qt4 AUR and fcitx-qt5 input method modules as your need, or the fcitx-im group to install fcitx and fcitx-qt5 . Without those modules, the input method may work on most applications but you may experience input method hang up, preview window screen location error or no preview error.

Applications below do not use GTK/Qt input module:

  • Applications use Tk, motif or xlib
  • Emacs, Opera, OpenOffice, LibreOffice, Skype, Wine, Java, Xterm, urxvt, WPS

Others

  • fcitx-ui-light , light UI for fcitx.
  • fcitx-table-extra adds Cangjie, Zhengma, Boshiamy support.
  • fcitx-table-other , tables for Latex, Emoji and others.

Others packages (including git version) are also available in the AUR. All components of fcitx will requires fcitx to restart after install.

Usage

Note: You need to have Chinese, Japanese, Korean or Vietnamese font installed to be able to enter the corresponding characters.

Desktop Environment Autostart

If you are using any XDG compatible desktop environment such as KDE, GNOME, Xfce, LXDE, after you re-login, the autostart should work out of box. If not run the fcitx executable. To see if fcitx is working correctly, open an application and press Ctrl+Space (the default shortcut for switching the input method) to invoke fcitx and input some words.

If fcitx failed to start with your desktop automatically or if you want to change the parameters to start fcitx, configure autostart or edit the fcitx-autostart.desktop file in your

/.config/autostart/ directory (copy it from /etc/xdg/autostart/ if it does not exist yet).

When other input methods with xim support are also running, fcitx may fail to start due to an xim error. Ensure that no other input methods are running before you start fcitx.

Also please set the following environment variables to prefer IM modules for GTK/Qt applications.

For i3 and Sway users, add exec --no-startup-id fcitx5 -d in your config file.

Set environment variables for IM modules

Define the environment variables to register the input method modules. Without these variables, applications may fallback to XIM protocol, except for qt5 applications which do not have XIM support and require an IM module in place.

As a general recommendation, define the following environment variables in

/.pam_environment . This file will be read by the pam_env module for all logins, including both X11 and Wayland sessions. See pam_env(8) and pam_env.conf(5) for details of its syntax and usage.

In case you do not want to define the above variables in

/.pam_environment for all your login sessions, please consider adding them to one of the start files for your X11 session. Most Display manager such as GDM and SDDM will source

/.xprofile for X11 sessions (but not for Wayland sessions). The syntax of

/.xprofile may depend on the specific Display manager and your login shell, consider the following example and modify it to suit your shell syntax:

For SLiM or startx users, they do NOT source

/.xprofile , but instead run

/.xinitrc to start your X11 session. Add the export lines to your

/.xinitrc before the exec YOUR_WM line:

/.xinitrc , but rather by default will source

/.xsession . The syntax is much the same as for

/.xinitrc , except the final line should just be YOUR_WM instead of exec YOUR_WM .

Re-login or reboot to make these environment changes effective.

If fcitx process does not start automatically, you might need to add fcitx & in your

/.xinitrc . If fcitx & does not start, type sleep 2 after it

  • Avoid .bashrc for this, see GregsWiki:DotFiles.
  • If all Qt apps have problem with fcitx, run qtconfig (qtconfig-qt4), and go to the third tab, make sure fcitx is in the Default Input Method combo-box.

Optionally, you can use the X Input Method (XIM) in your GTK and/or Qt programs without installing the above modules in which case you need to change the corresponding lines above as following:

If you change it in

/.xinitrc , add export .

Warning: Using XIM can sometimes cause problems including not being able to input, no cursor following, word selection window issue, application freeze on input method restart. For these XIM related problems, Fcitx cannot provide any fix or support. This is the same with any other input method framework, so please use the GTK and Qt input method modules instead of xim whenever possible Note: Gtk2 uses /usr/lib/gtk-2.0/2.10.0/immodules.cache as immodule cache file since 2.24.20. If you have set GTM_IM_MODULE_FILE environment variable or do not use install script of official packages to update the cache, please change/clear the environment variable and use /usr/bin/gtk-query-immodules-2.0 --update-cache to update immodule cache. Note: Qt5 applications no longer support XIM protocol as Qt4 did, and rely on IM modules entirely for communicating with fcitx.

Configuration

GUI configuration tools

fcitx provides a KDE configuration module ( kcm-fcitx ) and a GTK3 configuration tool ( fcitx-configtool ).

Run fcitx-config-gtk3 after fcitx-configtool is installed. Unset Only Show Current Language if you want to enable an input method for a different language.

Stop fcitx manually before changing configuration, or the change may be lost.

In order to enable spell checking, press Ctrl+Alt+h when fcitx is on an input method provided by fcitx-keyboard.

Input methods configuration

You can add/remove input methods in the GUI tools. Note that the search is case sensitive.

The first set input method is the inactive state, while all the rest will be active states. You generally want the inactive state to be one of the Keyboard options (e.g. "Keyboard - English (US)"). These options just input based on the keyboard layout in the name.

Under Global Config, the Trigger Input Method shortcut will only switch between the inactive and last used active state. The Scroll between Input Methods will by default only scroll between different active states, but can also be set to include the inactive state in the advanced settings. Furthermore, the Scroll between Input Methods shortcut has to be pressed in order, e.g. ALT_SHIFT will only activate if alt is pressed before shift .

Configuration settings for IME's can be found by by setting the keyboard to the desired IME and right-clicking the tray icon.

Change default UI

Fcitx support kimpanel protocol to provide better desktop integration.

Extend pinyin dictionary

Pinyin dictionary is located at

/.config/fcitx/pinyin . File pybase.mb is for single characters and file pyphrase.mb defines pinyin phrases. To extend them, put your file into /usr/share/fcitx/pinyin and restart fcitx.

Skins

You can download skins and extract them to one of the following directories, you can create the directory if it does not exist:

Cloud Pinyin configuration

After installing the fcitx-cloudpinyin input method, restart fcitx. If you could not find it in configuration GUI, enable advanced settings. The cloud query result will be added to current input method dictionary automatically.

If your network prevents you from accessing Google, change Cloud Pinyin source to Baidu.

The query result from cloud will list as secondary candidate by default and it is configurable. If the result already exists, only one item is shown.

Note: Set query result as first candidate is not recommend because the dictionary order will be changed if query returns an empty result

Tips and tricks

Shortcut keys

Some commonly used default shortcut keys:

  • Ctrl+Space - activates the input method
  • Left Shift - temporarily switches to English
  • Ctrl+Shift - switch between input methods
  • - / = - page forward/backward
  • Shift+Space - Full-width, half-width switching
Note: You can modify these shortcut keys in the global configuration of the configuration interface.

If you often use Fcitx under Vim, you can install the vim-fcitx AUR plugin, or add the following code to

/.vimrc . When exiting insert mode, Fcitx is automatically closed, otherwise the reverse:

Note: Due to calling external programs, this will significantly slow down the mapping that will repeatedly enter and exit insert mode. It is recommended to rewrite the relevant mapping, and use Vim with Python support in conjunction with fcitx.vim to improve efficiency.

Clipboard

Fcitx comes with a clipboard, the shortcut key is Ctrl+; , a small function to save the world.

Special symbols

/.config/fcitx/data/pySym.mb , the content of the file is as follows:

Enter a code directly to match the corresponding special symbol.

Note: The encoding can only be expressed with twenty-six lowercase letters; starting with v is invalid.

Clipboard Access

You can use fcitx to input text in you clipboard (as well as a short clipboard history and primary selection). The default trigger key is Ctrl-; . You can change the trigger key as well as other options in the Clipboard addon configure page.

Note: This is NOT a clipboard manager, it does not hold the selection or change its content as what a clipboard manager is supposed to do. It can only be used to input from the clipboard. Warning: Some clients do not support multi-line input, so you may see the multi-line clipboard content pasted as a single line using fcitx-clipboard. This is either a bug or feature of the program being used and it is not something fcitx is able to help with.

fcitx-remote

fcitx-remote is a commandline tool that can be used to control the fcitx state. It is installed with the fcitx package.

Input special character

Troubleshooting

Disable or change Extra key for trigger input method [sic]

This setting is under the Global Config tab and defaults to SHIFT Both, meaning that pressing either shift key will immediately change input methods. Although it should only apply when a shift key is pressed individually, it tends to randomly interrupt typing capital letters, selecting text with the keyboard, etc. while using standard keyboard input.

In addition, this setting may revert to default without warning at any time. To ensure fcitx's config cannot be modified, you must make fcitx's config file immutable: chattr +i

/.config/fcitx/config (as the root user).

Diagnose the problem

If you have problems using fcitx, eg. Ctrl+Space fail to work in all applications, then the first thing you should try is to diagnose using fcitx-diagnose . The output of fcitx-diagnose should contain the clue to most common problems. Providing the output of it will also help when you consult other people(eg. in IRC or forums).

Emacs

If your LC_CTYPE is English, you may not be able to use input method in emacs due to an old emacs bug. You can set your LC_CTYPE to something else such as zh_CN.UTF-8 before emacs starts to get rid of this problem.

Note that the corresponding locale should be generated on your your system.

The default fontset will use `-*-*-*-r-normal--14-*-*-*-*-*-*-*' as basefont (in src/xfns.c ), if you do not have one matched (like terminus or 75dpi things, you can look the output of `xlsfonts'), XIM can not be activated. According to FAQ and Fonts, it is likely that xorg-fonts-misc-otb AUR is the one that should be installed since xorg-fonts-misc no longer provides the required fontset.

Emacs Daemon

If you are using emacs daemon/client mode, LC_CTYPE should be set when starting the daemon. For example, by running emacs daemon with LC_CTYPE=zh_CN.UTF-8 emacs --daemon .

If starting emacs daemon from systemd, set Environment="LC_CTYPE=zh_CN.UTF-8" "XMODIFIERS=@im=fcitx" in the unit file.

( XMODIFIERS may need to be set explicitly here as systemd does not load .xprofile . Check the initial-environment variable in emacs to verify both variables are set correctly.)

Ctrl+Space fail to work in GTK programs

This problem sometimes happens especially when the locale is set as English. Please make sure your GTK_IM_MODULE is set correctly.

If you have set the *_IM_MODULE environment variables to fcitx but cannot activate fcitx, please check if you have installed the corresponding input method modules.

Some programs can only use xim, if you are using these programs, please make sure your XMODIFIERS is set properly and be aware of the problems you may have. These programs include all programs that are not using GTK or Qt (e.g. programs that use tk, motif, or xlib directly), emacs, opera, openoffice, libreoffice, skype.

If you cannot enable fcitx in gnome-terminal under Gnome and the above way does not work, try:

Buildin Chinese Pinyin Default NOT ACTIVE

If your locale is en_US.UTF-8 , fcitx did NOT enable the buildin Chinese Pinyin input method by default. There is only fcitx-keyboard-us input method enabled. You can get a notice by fcitx-diagnose command like this:

Then you should add Pinyin or Shuangpin input method to actived input methods by the GUI configure tool.

fcitx and KDE

For some reasons, KDE does not handle keyboard layouts properly. For example, if you switch from US (English) to LT (Lithuanian), all numbers on the keyboard should produce Lithuanian letters, but they still produce numbers as the output. This can be fixed by these steps:

  1. Turn off fcitx if it is running in the background.
  2. Disable stuff related to KDE:
    1. At System settings > Input devices > Layouts (tab) make sure that Configure layouts is unchecked.
    2. At System settings > Input devices > Advanced (tab) make sure that Configure keyboard options is unchecked.

    At this point you should have working layouts, native KDE layouts switch icon should appear and you can switch them by mouse scroll or click on it.

    Input method switched to English unintentionally

    For instance, in XMind, when the user presses Enter to create a node, input method is always switched to English, and has to be switched back to Chinese manually.

    To fix this issue, open the fcitx GUI configuration tool (provided by fcitx-configtool ), switch to tab Global Config, in dropdown menu Share State Among Window, select PerProgram or All.

    xmodmap settings being overwritten

    fcitx controls keyboard layout, so your xmodmap settings will be overwritten. Since 4.2.7, Fcitx will try to load

    IBus (Intelligent Input Bus) is an open source input framework for Linux and Unix.

    Emerge

    Except for the basic IBus framework, one or more engines should be installed. For example:

    For IBus to work with Qt 5 / KDE 5 / Plasma, the ibus USE flag needs to be set on at least dev-qt/qtgui and kde-plasma/plasma-desktop:

    And those packages rebuilt to reflect that change:

    Configuration

    Have a look at the eix output for more available engines:

    For graphical toolkit integration, app-i18n/ibus offers gtk (this refers to gtk+:2) and gtk3 flags.

    The app-i18n/im-chooser package can helpful for selecting the preferred input method. As of now all im-chooser packages in the Portage tree are marked unstable.

    If nothing starts (no ibus daemon) when a user logs in, put the following in the

    The installation can be finely tuned by running:

    ibus-setup can be used to set the preferred input methods, the system keyboard, or to add an icon in the taskbar.

    Note
    When using GNOME, type "ibus" in the search bar and launch "ibus-preferences" Tip
    The Input Method Panel widget in KDE may provide a better integrated experience with IBus on KDE. In 64-bit architectures, to launch IBus with Input Method Panel, first enable the widget and then run: user $ ibus-daemon -drx --panel=/usr/lib64/libexec/kimpanel-ibus-panel

    You may also use the command-line ibus utility, if you can't or don't want to use ibus-setup:
