Ubuntu 16.04 LTS 安装搜狗拼音输入法

记录一下Ubuntu 16.04 LTS中如何安装搜狗拼音输入法

参考:

下载安装Sougou输入法

在搜狗输入法官方页面,下载适合系统的deb安装文件,安装

1
2

4
sudo dpkg -i sogoupinyin_2.1.0.0086_amd64.deb
# 如果出现依赖未安装
sudo apt install -f
sudo dpkg -i sogoupinyin_2.1.0.0086_amd64.deb

设置Fcitx输入法

在Ubuntu中,打开System Settings -> Language Support,根据提示安装完整的语言支持,并将Keyboard input method system设为fcitx

在Fcitx中添加搜狗输入法

打开Terminal(快捷键 Ctrl + Alt + T),输入fcitx-configtool,点击添加,去掉勾选的Only Show Current Language,添加Sougou Pinyin

在System Settings -> Keyboard -> Shortcuts -> Typing中,将Switch to next source和Switch to previous source的选项,都设为Diabled(点击选项后,按Backspace)。这样可以禁用系统的切换输入法快捷键,搜狗拼音输入法的默认快捷键为Ctrl + ,

在Sublime Text 3中添加搜狗输入法的支持

Sublime Text是一款跨平台下十分好用的文本编辑软件,然而在Ubuntu下,默认安装的Sublime Text 3不支持搜狗中文输入法,需要手动编译一个共享库

安装依赖软件

安装编译共享库的依赖’build-essential’和’libgtk2.0-dev’

1
sudo apt install build-essential libgtk2.0-dev

编写sublime-imfix.c文件

在该文件所在目录下,编译

1
gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC

编译后可以得到libsublime-imfix.so这个共享库

添加共享库到Sublime Text 3

首先,测试一下是否在Sublime Text 3中可以输入中文

1
LD_PRELOAD=./libsublime-imfix.so subl

如果可以正常使用搜狗输入法,进行接下来的配置

将libsublime-imfix.so拷贝到系统库的默认路径下:

1
sudo cp libsublime-imfix.so /usr/lib

修改Sublime的执行文件/usr/bin/subl

1
2
#!/bin/sh
LD_PRELOAD=/usr/lib/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@"

修改Sublime的快捷方式/usr/share/applications/sublime_text.desktop:

1
2
3
4
5
6
7
# Exec=/opt/sublime_text/sublime_text %F
# 修改为
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /opt/sublime_text/sublime_text' %F
# Exec=/opt/sublime_text/sublime_text -n
# 修改为
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /opt/sublime_text/sublime_text' -n

这样就可以在命令行subl和系统Application中的Sublime Text 3中输入中文了
