ubuntu下sublime text3无法输入中文的解决办法

最后系统换为ubuntu，发生了一大堆问题，也解决了一大堆问题。因为写前端代码我现在离不了sublime, 不曾想在ubuntu中装好sublime后竟然无法输入中文，吓哭…

我的电脑环境

ubuntu 14.04 LTS
sublime text 3
搜拘输入法

保存下述代码为sublime-imfix.c文件

安装 C/C++ 的编译环境和 gtk libgtk2.0-dev

折叠代码块SHELL 复制代码

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

编译共享内库

在Terminal中进入上述代码的保存位置

折叠代码块 复制代码

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

将libsublime-imfix.so拷贝到sublime_text所在文件夹

直接一条命令完成就好啦～

折叠代码块BASH 复制代码

sudo mv libsublime-imfix.so /opt/sublime_text/

修改文件/usr/bin/subl的内容

折叠代码块 复制代码

sudo gedit /usr/bin/subl

然后将

折叠代码块 复制代码

#!/bin/sh
exec /opt/sublime_text/sublime_text "$@"

修改为

折叠代码块 复制代码

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

此时，在命令中执行 subl 打开sublime将可以搜狗输入法的中文输入

修改文件sublime_text.desktop的内容， 以使鼠标打开的方式也可正常使用中文输入

折叠代码块 复制代码

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

将[Desktop Entry]中的字符串

折叠代码块 复制代码

Exec=/opt/sublime_text/sublime_text %F

修改为

折叠代码块 复制代码

Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text %F"

将[Desktop Action Window]中的字符串

折叠代码块 复制代码

Exec=/opt/sublime_text/sublime_text -n

修改为

折叠代码块 复制代码

Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text -n"

将[Desktop Action Document]中的字符串

折叠代码块 复制代码

Exec=/opt/sublime_text/sublime_text --command new_file

修改为

折叠代码块 复制代码

Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text --command new_file"

注意：
修改时请注意双引号””,否则会导致不能打开带有空格文件名的文件。
此处仅修改了/usr/share/applications/sublime-text.desktop，但可以正常使用了。
opt/sublime_text/目录下的sublime-text.desktop可以修改，也可不修改。

后记

初次使用ubuntu做开发，希望将遇到的问题记录下来，方便自己的同时如若能帮助他人亦是极好的。
