ubuntu下sublime text 3无法输入中文

按照如下步骤操作即可输入中文：

1. 保存下述代码为sublime-imfix.c文件

/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang
 
gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
LD_PRELOAD=./libsublime-imfix.so subl
*/
#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++编译环境和 gtk libgtk

sudo apt-get install build-essential

sudo apt-get install libgtk2.0-dev

3. 编辑共享库文件

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

将libsublime-imfix.so文件放在安装目录下，默认/opt/sublime_text/

4. 编辑sublime_text.desktop文件,如下

[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
Exec=bash -c 'LD_PRELOAD=/path_to_sublime_text/libsublime-imfix.so /path_to_sublime_text/sublime_text' %F
Icon=/path_to_sublime_text/Icon/48x48/sublime_text.png
Terminal=false
MimeType=text/plain;
Icon=sublime-text
Categories=TextEditor;Development;
StartupNotify=true

Actions=Window;Document

[Desktop Action Window]
Name=New Window
Exec=/opt/sublime_text/sublime_text -n
OnlyShowIn=Unity;


[Desktop Action Document]
Name=New File
Exec=/opt/sublime_text/sublime_text --command new_file
OnlyShowIn=Unity;

将它放在/usr/share/applications下替换原来的，就可以使用了
