Ubuntu 16.04下解决sublime text3无法输中文问题

首先介绍一下常规方法。文章最后附有shell一键脚本可供懒人使用。

常规方法

一、系统已成功安装搜狗输入法
二、保存下面的代码到文件sublime_imfix.c(位于~目录)

#include <gtk/gtkimcontext.h>
    void gtk_im_context_set_client_window (GtkIMContext *context,
              GdkWindow    *window)
    {
      GtkIMContextClass *klass;
      g_return_if_fail (GTK_IS_IM_CONTEXT (context));
      klass = GTK_IM_CONTEXT_GET_CLASS (context);
      if (klass->set_client_window)
        klass->set_client_window (context, window);
      g_object_set_data(G_OBJECT(context),"window",window);
      if(!GDK_IS_WINDOW (window))
        return;
      int width = gdk_window_get_width(window);
      int height = gdk_window_get_height(window);
      if(width != 0 && height !=0)
        gtk_im_context_focus_in(context);
    }

如果出现以下问题:

则输入以下命令后再编译

sudo apt-get install libgtk2.0-dev

三、将上一步的代码编译成共享库libsublime-imfix.so，命令

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

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

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

五、修改文件/usr/bin/subl的内容

sudo gedit /usr/bin/subl

将

#!/bin/sh
exec /opt/sublime_text/sublime_text "[e-mail]"

修改为

#!/bin/sh
LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text "[e-mail]"

此时，在命令中执行 subl 将可以使用搜狗for linux的中文输入
六、为了使用鼠标右键打开文件时能够使用中文输入，还需要修改文件sublime_text.desktop的内容
sudo gedit /usr/share/applications/sublime_text.desktop
将[Desktop Entry]中的字符串

Exec=/opt/sublime_text/sublime_text %F

修改为

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

Exec=/opt/sublime_text/sublime_text -n

修改为

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

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

修改为

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

这样，在图形界面里通过右键打开也可以使用搜狗输入法了。

一键脚本

一键脚本完全基于常规方法。只是写成了脚本而已。运行起来没有提示，没有特别意外的情况基本是直接成功的。运行完可以测试一下是否能够正常使用搜狗输入法。
下面贴上代码：

#!/bin/bash
#开始写入文件
echo "#include <gtk/gtkimcontext.h>" > ~/sublime_imfix.c
echo "  void gtk_im_context_set_client_window (GtkIMContext *context," >> ~/sublime_imfix.c
echo "            GdkWindow    *window)" >> ~/sublime_imfix.c
echo "  {" >> ~/sublime_imfix.c
echo "    GtkIMContextClass *klass;" >> ~/sublime_imfix.c
echo "    g_return_if_fail (GTK_IS_IM_CONTEXT (context));" >> ~/sublime_imfix.c
echo "    klass = GTK_IM_CONTEXT_GET_CLASS (context);" >> ~/sublime_imfix.c
echo "    if (klass->set_client_window)" >> ~/sublime_imfix.c
echo "      klass->set_client_window (context, window);" >> ~/sublime_imfix.c
echo '    g_object_set_data(G_OBJECT(context),"window",window);' >> ~/sublime_imfix.c
echo "    if(!GDK_IS_WINDOW (window))" >> ~/sublime_imfix.c
echo "      return;" >> ~/sublime_imfix.c
echo "    int width = gdk_window_get_width(window);" >> ~/sublime_imfix.c
echo "    int height = gdk_window_get_height(window);" >> ~/sublime_imfix.c
echo "    if(width != 0 && height !=0)" >> ~/sublime_imfix.c
echo "      gtk_im_context_focus_in(context);" >> ~/sublime_imfix.c
echo "  }" >> ~/sublime_imfix.c


#检查是否已安装libgtk2.0-dev
((installed=0))
dpkg -s libgtk2.0-dev > /dev/null
((installed=$?))
if  [ "$installed" = 1 ];then
    echo  -e "\033[31mlibgtk2.0-dev\033[36m has not been installed! We have to install it first!"
    echo  -e "\033[Installing \033[31mlibgtk2.0-dev\033[0m..."
    sudo sudo apt-get install libgtk2.0-dev
fi
#编译libsublime-imfix.so
gcc -shared -o ~/libsublime-imfix.so ~/sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC
#清理源码文件
rm ~/sublime_imfix.c
#移动编译文件
sudo mv ~/libsublime-imfix.so /opt/sublime_text/
#修改文件/usr/bin/subl的内容
sudo sh -c 'echo "#!/bin/sh" > /usr/bin/subl'
sudo sh -c "echo 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text \"\[e-mail]\"' >> /usr/bin/subl"

#修改/usr/share/applications/sublime_text.desktop
sudo sed -i -e 's|Exec=/opt/sublime_text/sublime_text %F|Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text %F"|' /usr/share/applications/sublime_text.desktop

sudo sed -i -e 's|Exec=/opt/sublime_text/sublime_text -n|Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text -n"|' /usr/share/applications/sublime_text.desktop

sudo sed -i -e 's|Exec=/opt/sublime_text/sublime_text --command new_file|Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text --command new_file"|' /usr/share/applications/sublime_text.desktop
echo "All done here! Try it out!"

shell脚本的运行方式
将以上代码保存为任意文件名.sh，例如myscript.sh
然后在终端中输入：

chmod +x myscript.sh
./myscript.sh

即可。
