解决openSUSE中Sublime Text 3的中文显示和输入问题

Posted 2020-10-15

 

Sublime Text 2是免安装的，下载完解压就可以了。我这边解压路径是/home/fhp/App/SublimeText2

 

为了能在终端直接使用sublime打开文件，添加软链接:
sudo ln -s /home/fhp/App/SublimeText2/sublime_text /usr/bin/sublime

添加desktop:
sudo sublime /usr/share/applications/sublime.desktop

修改文件关联:
编辑sudo sublime /usr/share/applications/defaults.list:
替换文件中所有gedit.desktop为sublime.desktop。

 

首先，将这段广为流传的代码保存为sublime_imfix.c，并编译成共享库，作为输入法补丁。

       GdkWindow * win = g_object_get_data(G_OBJECT(im_context),"window");

}

 

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

 

顺利完成后，将编译的libsublime-imfix.so文件复制到Sublime的安装目录：

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

然后，准备用来加载共享库的shell脚本。

 

将以下shell脚本代码保存为sublime_text.sh

 

#!/bin/bash

SUBLIME_HOME="/opt/sublime_text"
LD_LIB=$SUBLIME_HOME/libsublime-imfix.so
sh -c "LD_PRELOAD=$LD_LIB $SUBLIME_HOME/sublime_text [email protected]"

 

 授予文件可执行权限：

sudo chmod a+x sublime_text.sh

 把脚本文件复制到Sublime安装目录：

sudo cp sublime_text.sh /opt/sublime_text/

 最后，修改用来启动sublime的sublime_text.desktop文件，以便从系统菜单等处点击图标直接启动编辑器就可正常输入中文。
将sublime_text.desktop文件复制到自己的用户目录，右键打开设置窗口并切换到应用程序标签页，修改命令一项里的sublime_text为sublime_text.sh后确定保存。点击图标测试能正常启动编辑器并且切换输入法后，将修改过的文件复制到usr/share/applications/目录。

sudo cp sublime_text.desktop usr/share/applications/


（sublime_text.desktop文件所在的位置与安装方式有关，如果直接下载的压缩包，文件就在解压的目录里。
如果通过加载官方源用包管理器安装，文件一般在/usr/share/applications/目录里。
直接用chmod命令修改系统路径里的desktop文件权限修改属性是行不通的，权限不足的情况下尽量新建文件或者复制到用户目录修改后再用覆盖/usr/share/applications/里的。其他方法相对复杂。）
