在Ubuntu 14.04中使SublimeText 3支持中文输入法

    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

• Ubuntu14.04

• 搜狗输入法 for Linux

• Sublime text 3

• 
  

2.拷贝如下代码到文件sublime-imfix.c文件中，该文件需要自己创建，随便放到那里都行。

/*

 * 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);

}

3.编译

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. 鼠标右键打开支持中文

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

这样就通过快捷方式打开SublimeText 3就可以支持中文输入了。

5.命令行打开支持中文

    修改文件/usr/bin/subl的内容

    sudo gedit /usr/bin/subl

    将

    #!/bin/sh

    exec /opt/sublime_text/sublime_text "$@"

    修改为

    #!/bin/sh

    LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@"

    此时，在命令中执行 subl 将可以使用搜狗for linux的中文输入
