Sublime text 3不支持中文输入法，下面是我结合网上的各种资料摸索实践了一遍，为Sublime text 3成功添加了搜狗拼音输入法，特此记录以备参考。

前提条件：

事先安装并配置好搜狗拼音法和Sublime text 3编辑器，参考本博客相关文章。

1.安装相关依赖库  
sudo apt-get install build-essential libgtk2.0-dev

2.编译相关动态库  
编译如下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 <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 = 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);
    }

gcc -shared -o libsublime-imfix.so sublime\_imfix.c  \`pkg-config --libs --cflags gtk+-2.0\` -fPIC  
得到libsublime-imfix.so共享库，复制到Sublime text 3的安装目录(通常是/opt/sublime\_text/)下  
sudo cp libsublime-imfix.so /opt/sublime\_text/  
同时在终端中输入如下命令, subl是安装好SublimeText 3后的程序启动命令：  
    LD\_PRELOAD=./libsublime-imfix.so subl  
如果一切正常，在启动之后，搜狗输入法就能可以输入了，但是下面还需要做相关的配置。  
3.编辑启动项  
sudo vim /usr/bin/subl  
修改/usr/bin/subl文件，将：  
sudo gedit /usr/bin/subl  
改为  
LD\_PRELOAD=/opt/sublime\_text/libsublime-imfix.so exec /opt/sublime\_text/sublime\_text "$@"  
保存，在命令行执行运行subl(注意不是sudo subl)，检查看是否可以正常使用搜狗输入法, 正常情况下会成功。  
为了能在Unity上的Sublime text 3图标打开时也能使用，下面继续修改文件sublime\_text.desktop的内容  
sudo vim /usr/share/applications/sublime-text.desktop  
修改如下三处地方  
将\[Desktop Entry\]中的字符串  
Exec=/opt/sublime\_text/sublime\_text %F  
修改为  
Exec=bash -c "LD\_PRELOAD=/opt/sublime\_text/libsublime-imfix.so exec /opt/sublime\_text/sublime\_text %F"  
将\[Desktop Action Window\]中的字符串  
Exec=/opt/sublime\_text/sublime\_text -n  
修改为  
Exec=bash -c "LD\_PRELOAD=/opt/sublime\_text/libsublime-imfix.so exec /opt/sublime\_text/sublime\_text -n"  
将\[Desktop Action Document\]中的字符串  
Exec=/opt/sublime\_text/sublime\_text --command new\_file  
修改为  
Exec=bash -c "LD\_PRELOAD=/opt/sublime\_text/libsublime-imfix.so exec /opt/sublime\_text/sublime\_text --command new\_file"

![Center][]  
使用vimdiff比较发现，它和/opt/sublime\_text/applications/sublime\_text.desktop几乎相同，不过前者主要是负责unity图标的，但这样就可以正常使用了。  
opt/sublime\_text/目录下的sublime-text.desktop可以修改，也可不修改。但是如果只修改后者，仍将无法使用搜狗拼音输入法。

4.验证

正常情况下, 如截图所示
