解决Sublime-Text-3在ubuntu下中文输入的问题

  在ubuntu下使用ST这神器已经一段日子了,但是一直有个纠结的问题,就是中文输入非常坑爹,曾经一段时间,使用inputHelper这个插件来解决,

但是……每次都要按个快捷键,弹出一个小小小框来输入中文,能这样欺负人吗?在无数次翻阅前辈的博客之后……一如既往的坑爹,因为太多都是copy,

很多残缺,或者我的亲ubuntu14.04一点反应都没有,于是,一次偶然的机会,才发现sublime text自己就有个论坛……这就是浮躁的年轻人,咋就不会

看看脚下呢……马上来记录一下今天的解决方案:

  1. 首先找到ST的安装目录,我的是/opt/sublime_text/,创建一个sublime-imfix.c的文件,由于网上各种的压缩代码非常坑爹,就不压缩了,代码如下:

/*

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); 

}

  2. 安装C/C++的编译环境和gtk libgtk2.0-dev 命令如下:

  sudo apt-get install build-essential  

  sudo apt-get install libgtk2.0-dev
  sudo apt-get install gtk+-2.0

  3. 编译成共享库

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

  4. 命令行启动sublime,检测一下能否输入中文:

  LD_PRELOAD=./libsublime-imfix.so subl //我的sublime是deb安装的,所以命令行可用subl

  5. 接下来我们还要通过修改sublime-text-2.desktop达到点击图标启动。 

  mv libsublime-imfix.so /usr/lib



  cd /usr/share/applications



  sudo gedit sublime_text.desktop

  打开sublime_text.desktop后,修改如下

  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 

  完成,即可,当然我的用是fcitx输入法框架,ibus的就……一脸的泪,其实有点感觉,方便即可……实在不行就用win系统也是不错的选择。
