Ubuntu下 Sublime Text 中文输入

完美解决 Linux 下 Sublime Text 中文输入
测试系统：Ubuntu 16.04 （理论上所有 Linux 发行版都通用）
输入法：搜狗拼音linux版
Sublime Text 版本：Sublime Text 3 dev（Build 3026）

1. 下载共享库
   点击下载 libsublime-imfix.so
   然后解压出来后缀为.rar

rar x fileName.rar 

2. 保存下述代码为 sublime-imfix.c文件

  /*

Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.

gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
LD_PRELOAD=./libsublime-imfix.so subl

//The caret width is 2;
//Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.
if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {

}
}

}

}

3. 安装 C/C++ 的编译环境和 gtk libgtk2.0-dev

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

4. 编译共享内库

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

5. 设置 LD_PRELOAD 并启动 Sublime Text

  LD_PRELOAD=./libsublime-imfix.so subl

6. 为了使用方便，还需要做一下配置
   不必每次都输入LD_PRELOAD打开sublime text 3，需要修改sublime图标链接方式 首先将共享库复制到系统默认路径中

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

打开修改 sublime 配置文件

sudo vim /usr/share/applications/sublime_text.desktop

修改地方 ①将

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

修改地方 ②将

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

这样就通过快捷方式打开SublimeText 3就可以支持中文输入了
