sublime 在ubuntu下不支持中文输入法,这对于开发来说难免有很多不方便的地方

使用自定义程序方法启动sublime2./sublime3

首先,我们进入sublime的配置目录下:

cd /opt/sublime-text2

这里,我们新建一个代码文件来进行编译生成我们的自定义程序

sudo touch sublime-imfix.c

打开文件

sudo gedit sublime-imfix.c

然后输入以下代码

接下来,安装C/C++的编译环境和gtk libgtk2.0-dev

1
2
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev

如果在安装libgtk2.0-dev时发现us的源难以连接,则将source.list软件源替换为国内源地址,可以使用
163的镜像地址然后进行下载。下载完成后对c程序进行编译:

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

编译完成后,为了点击图标能够自动打开程序,我们对sublime-2.desktop进行修改:

sudo gedit /usr/share/applications/sublime-text.desktop

修改快捷方式的启动,修改如下:

[Desktop Entry]

Name=New File
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text_2/libsublime-imfix.so /opt/sublime_text_2/sublime_text' --command new_file

其中主要是exec的修改,其他不用修改。以后启动直接点击桌面图表或者dash中的图标启动,会调用desktop中的代码,如果使用terminal直接启动则依然不能使用中文。
