ubuntu 16.04 sublime 3安装搜狗输入法

在Ubuntu 16.04中安装了SublimeText 3之后发现既然不支持输入中文。

根据网上资料和自身的安装过程,解决办法总结如下:

1. SublimeText3的安装

    本文采用的是从官方网站上下载64位的.deb文件

    sudo dpkg -i sublime-text_build-3114_amd64.deb    

2. 相关依赖软件的安装

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

3. 拷贝如下代码到文件sublime_imfix.c文件中(该文件需要自己创建,可放任意位置)

    /*

     * sublime-imfix.c

     * Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.

     * 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

    #include

    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);

    }

    按照文件头上注释所说的编译该文件,在终端里进入到存放该文件的目录中,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。

4. 中文输入

    到这里默认已经装好了中文输入法(搜狗输入法linux版)。得到第3步中的库libsublime-imfix.so之后,先试试看是否能正常使用中文输入法,在终端中输入如下命令:

    LD_PRELOAD=./libsublime-imfix.so subl             #subl是安装好SublimeText 3后的程序启动命令

如果一切正常,在启动之后,搜狗输入法就能可以输入了。

5. 为了方便

    在第4步中如果每次都输入LD_PRELOAD这样显得太不方便了,在这里提供简单修改图标连接的方式,快速打开SublimeText。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 vim /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


    也可以相似方式修改/usr/bin/subl,以便命令行方式启动带中文输入法

    这样就通过快捷方式打开SublimeText 3就可以支持中文输入了。

注:第五步仅限使用.deb文件安装的情况,如果使用源码安装的则需要变通一下,写个脚本将LD_PRELOAD加上即可
