Linux下Sublime Text 2 中文输入

转载] http://my.oschina.net/tsl0922/blog/113495
一直没办法在Linux下的sublime里输入中文，在网上找了很多办法都没成功，这个转载的办法需要gcc的编译介入，虽然麻烦却也一次搞定了这个麻烦。

1. 安装gtk开发环境(当然必须有gcc了)：
sudo apt-get install libgtk2.0-dev
sudo apt-get install pkg-config
sudo apt-get install fcitx //安装小企鹅输入法, - =键是选字翻页
im-switch -s fcitx //切换系统默认的输入法

CentOS6.4 使用sohu的yum源
sudo yum -y install gtk+*

2. 保存代码到文件sublime_imfix.c
    /*
    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
    LD_PRELOAD=./libsublime-imfix.so sublime_text
    */
    #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);
    }

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

4. 拷贝 libsublime-imfix.so 文件到 sublime Text的软件目录下面
sudo cp libsublime-imfix.so /usr/lib/SublimeText2/

5. 建立启动文件 sublime_text.sh, 内容如下：
SUBLIME_HOME="/Your/Path/SublimeText2"
LD_LIB=$SUBLIME_HOME/libsublime-imfix.so
sh -c "LD_PRELOAD=$LD_LIB $SUBLIME_HOME/sublime_text $@"

修改权限
$ sudo chmod 755 sublime_text.sh

6. 做成系统命令
sudo ln -s /Your/Path/SublimeText2/sublime_text.sh /usr/bin/sublime

7. 重新启动系统
OK,搞定
