1. 编译共享内库

sublime-imfix.c(保存在文件夹Sublime Text 2下)：

/*
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

*/
#include <gtk/gtk.h>
#include <gdk/gdkx.h>
typedef GdkSegment GdkRegionBox;

struct _GdkRegion
{
  long size;
  long numRects;
  GdkRegionBox *rects;
  GdkRegionBox extents;
};

GtkIMContext *local_context;

void
gdk_region_get_clipbox (const GdkRegion *region,
            GdkRectangle    *rectangle)
{
  g_return_if_fail (region != NULL);
  g_return_if_fail (rectangle != NULL);

  rectangle->x = region->extents.x1;
  rectangle->y = region->extents.y1;
  rectangle->width = region->extents.x2 - region->extents.x1;
  rectangle->height = region->extents.y2 - region->extents.y1;
  GdkRectangle rect;
  rect.x = rectangle->x;
  rect.y = rectangle->y;
  rect.width = 0;
  rect.height = rectangle->height; 
  //The caret width is 2; 
  //Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.
  if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {
        gtk_im_context_set_cursor_location(local_context, rectangle);
  }
}

//this is needed, for example, if you input something in file dialog and return back the edit area
//context will lost, so here we set it again.

static GdkFilterReturn event_filter (GdkXEvent *xevent, GdkEvent *event, gpointer im_context)
{
    XEvent *xev = (XEvent *)xevent;
    if(xev->type == KeyRelease && GTK_IS_IM_CONTEXT(im_context)) {
      GdkWindow * win = g_object_get_data(G_OBJECT(im_context),"window");
      if(GDK_IS_WINDOW(win))
        gtk_im_context_set_client_window(im_context, win);
    }
    return GDK_FILTER_CONTINUE;
}

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);

  if(!GDK_IS_WINDOW (window))
    return;
  g_object_set_data(G_OBJECT(context),"window",window);
  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);
    local_context = context;
  }
  gdk_window_add_filter (window, event_filter, context); 
}

2. 安装C/C++的编译环境和gtk libgtk2.0-dev

sudo apt-get install build-essential

sudo apt-get install libgtk2.0-dev

3. 编译共享内库

    在文件夹Sublime Text 2下运行：

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

    这时，在文件夹 Sublime Text 2下会生成libsublime-imfix.so文件。

4. 将整个文件夹复制到/usr/share下

sudo cp -R /home/lcj/Sublime\ Text\ 2/. /usr/share/Sublime

5. 在/usr/share/Sublime下编写sublime.sh文件

cd /usr/share/Sublime
LD_PRELOAD=./libsublime-imfix.so ./sublime_text

并且给它设定权限：

sudo chmod 777 sublime.sh

    这时，你可以手动运行指令：

./sublime.sh

    就会弹出会编写中文的sublime了。

6. 通过ln来设定软连接

sudo ln -s /usr/share/Sublime/sublime.sh /usr/bin/sublime

    这样，我们在terminal下直接输入：

sublime

就可以运行sublime了。

7. 设定桌面

进入/usr/share/applications:

cd /usr/share/applications

编写文件sublime.desktop:

[Desktop Entry]
Name=Sublime
Comment=Sublime Text 2
TryExec=sublime
Exec=sublime
Icon=sublime
Type=Application
Categories=GNOME;GTK;Utility;TerminalEmulator;System;
StartupNotify=true
X-Ubuntu-Gettext-Domain=sublime
X-Ayatana-Desktop-Shortcuts=NewWindow;
Keywords=terminal;shell;prompt;command;commandline;
[NewWindow Shortcut Group]
Name=Open a New Window
Exec=sublime
TargetEnvironment=Unity

大功告成！打开你的应用程序去搜索sublime吧，只是图标有点丑！
