Sublime Text是一个功能强大的跨平台代码编辑器，但是在Linux系统下一直无法输入中文。由于目前已把Ubuntu当作主力操作系统使用，平时使用Sublime Text处理文本时经常需要输入中文，所以整理一下Sublime Text打中文补丁的过程。

背景环境

  • 操作系统：Ubuntu 15.04
  • Sublime Text版本：3

安装Fcitx

Ubuntu 15.04默认输入法既为Fcitx，如果你的Ubuntu版本低于15.04可能需要安装Fcitx，安装方法可以从网络搜索。

安装补丁

新建文件sub-fcitx.c，建议放在Sublime Text的所在目录下，将下面的代码复制进去

安装编译环境

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

编译文件

切换到sub-fcitx.c，所在目录，编译生成so文件

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

目录下会多一个libsublime-imfix.so文件

添加启动脚本

修改目录下的sublime_text.desktop文件，内容如下(注: 路径改为实际路径)

为sublime_text.desktop文件添加执行权限

1
chmod +x sublime_text.desktop

以后双击 sublime_text.desktop 就能支持Sublime Text了，运行后也可以锁定到启动器上以方便启动。
