测试系统：Ubuntu 12.10 （理论上所有 Linux 发行版都通用）

输入法：Fcitx 4.2.6.1

Sublime Text 版本：Sublime Text 3 dev（Build 3026）

\--------------------------------------------------------------------

我的电脑配置是：linuxMint17.1

输入法：搜狗输入法

Sublime Text 版本：Sublime Text 3

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++ 的编译环境和 gtk libgtk2.0-dev

sudo apt-get install build-essential
    sudo apt-get install libgtk2.0-dev

3. 编译共享内库

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

4. 设置 LD\_PRELOAD 并启动 Sublime Text

LD_PRELOAD=./libsublime-imfix.so subl

5. 修改 `/usr/share/applications/sublime_text.desktop` 为

[Desktop Entry]
    [...]
    Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text %F
    [...]
    
    [Desktop Action Window]
    [...]
    Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text -n
    [...]
    
    [Desktop Action Document]
    [...]
    Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text --command new_file
    [...]

不要忘了把 `libsublime-imfix.so` 放到 `/opt/sublime_text/` 中

6. 修改 `/usr/bin/subl` 为

\#!/bin/sh

export LD\_PRELOAD=/opt/sublime\_text/libsublime-imfix.so  
exec /opt/sublime\_text/sublime\_text "$@"

重启电脑，可以看到Sublime能够输入中文了。
