Ubuntu14.04下Sublime Text 3解决无法输入中文

在Ubuntu 14.04中安装了SublimeText 3之后发现既然不支持输入中文，于是在网上搜罗一下，发现很多人遇到了同样的问题，但是解决办法大该就只有一个。下面根据自身的安装及解决办法总结如下：

1. SublimeText 3的安装

安装方式有多种，本文所描述的是从官网下载与自己系统相匹配的.deb 文件，下载后双击即可安装。

2. 相关依赖软件的安装

sudo apt-get install build-essential libgtk2.-dev

3. 支持中文输入

拷贝如下代码到文件sublime-imfix.c文件中，该文件需要自己创建，放在主文件夹下(home文件夹)

 #include <gtk/gtk.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);
 }

打开终端，输入如下命令：

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

最后在当前目录下得到libsublime-imfix.so这个共享库。再将libsublime-imfix.so拷贝到系统库的默认路径中：

sudo cp libsublime-imfix.so /usr/lib/

修改/usr/share/applications/sublime_text.desktop文件

sudo gedit /usr/share/applications/sublime_text.desktop

打开后将Exec=/opt/sublime_text/sublime_text %F修改为

Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /opt/sublime_text/sublime_text' %F

将Exec=/opt/sublime_text/sublime_text -n修改为

Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /opt/sublime_text/sublime_text' -n

保存关闭，重新打开SublimeText 3就可以支持中文输入了。到这里默认已经装好了中文输入法（搜狗输入法linux版）。
