本文介绍了一种通过自定义库解决Sublime Text在Linux环境下中文输入法支持不佳的方法。涉及依赖安装、源代码编译及配置过程。

安装编译所需依赖

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

源代码

 /*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang <jianzhong.huang at i-soft.com.cn>
gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC

}

编译

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

启动sublime

 LD_PRELOAD=./libsublime-imfix.so subl

添加到默认启动

查看sublime-text所在文件夹：

 which subl
vi /usr/bin/subl

复制libsublime-imfix.so到sublime所在文件夹：

 sudo cp libsublime-imfix.so /opt/sublime_text

方法一

 cd /usr/bin/
sudo touch sublime_text3 
sudo chmod a+x sublime_text3
sudo vi sublime_text3

添加内容：

 #!/bin/bash
SUBLIME_HOME="/opt/sublime_text"
LD_LIB=$SUBLIME_HOME/libsublime-imfix.so
sh -c "LD_PRELOAD=$LD_LIB $SUBLIME_HOME/sublime_text $@"

保存退出。

编辑/usr/share/applications将其中的三处/opt/sublime_text/sublime_text修改为/usr/bin/sublime_text3。

这样无论在终端中执行sublime_text3还是双击或者右键打开文本都可以输入中文了。

方法二

编辑/usr/bin/subl，在最后一行上面添加：

 export LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so

编辑/usr/share/applications将其中的三处/opt/sublime_text/sublime_text替换为/usr/bin/subl
