问题描述

在ubuntu下想使用sublime，但是不能输入中文，很尴尬啊，参考了一位中国大神的方法，再针对自己实际情况修改，成功了，哈哈。

使用环境

Ubunt Kylin 14.04, sublime text 2, 搜狗输入法。

解决方法

1. 保存下面的代码为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 = ;
   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 ==  && 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 !=  && height !=) {
     gtk_im_context_focus_in(context);
     local_context = context;
   }
   gdk_window_add_filter (window, event_filter, context);
 }

2. 编译动态库：

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

编译之前请确保检查一下gtk+-2.0库是否具备：

pkg-config --libs --cflags gtk+-2.0

如果提示有库找不到，自己安装一下：

sudo apt-get install gtk+-2.0

3.设置LD_PRELAD路径

让每次启动编辑器前，先把刚才编译的库加载。因为不想每次启动编辑器都打长长的命令，所以我使用如下脚本来启动：

 #!/bin/bash
 SUBLIME_HOME="/opt/SublimeText2"
 LD_LIB=$SUBLIME_HOME/libsublime-imfix.so
 EXE=$SUBLIME_HOME/sublime_text
 bash -c "LD_PRELOAD=$LD_LIB $EXE $@"

为了启动更加方便，可以把脚本取名为sublime，放在自己的PATH环境下，就可以随时输入sublime启动编辑器了，不错吧！

4.要注意的问题

启动脚本的SUBLIME_HOME的路径中不能有空格，否则编辑器启动后还是不能输入中文；如果编辑器的路径确实有空格，可以做个软链接，这样在脚本中可以避免带空格了。
