Linux下的sublime里输入中文

我的系统是ubuntu 14.04 LTS，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。

0.安装 fcitx
sudo apt-get install fcitx-table-wbpy

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

2. 保存代码到文件sublime_imfix.c

/*

Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.

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

#include 
#include 
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 /opt/sublime_text_2

5. 建立启动文件 sublime_text.sh, 内容如下：
   SUBLIME_HOME="/opt/sublime_text_2"
   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 /opt/sublime_text_2/sublime_text.sh /usr/bin/sublime
   或者改动启动器，把原来的命令改成 /opt/sublime_text_2/sublime_text.sh

7. 重新启动系统
   OK,搞定
