[操作系统]允许Sublime编辑器在Ubuntu上输入中文


  Sublime Text是一款功能非常强大的轻量级代码编辑器,有关功能介绍和使用可以看我另一篇文章的描述http://www.cnblogs.com/jaxu/p/5037547.html

  不过,在Ubuntu系统上Sublime Text不支持输入中文,如何解决呢?

  搜索百度和Google,在github上发现了一个解决方案,经过尝试可以使用。

  其基本思路就是用C编写一个hotfix然后编译成共享库,移到Sublime Text的安装目录中,启动的时候带上这个共享库。步骤和shell命令在github上已经写得非常清楚了,这里我再详细描述一下。

1. 编写sublime-imfix.c源文件,放在~/home目录下(其实任何目录都可以)。源代码文件在github上有下载,我这里也给一份,方便copy:

/*sublime-imfix.cUse 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` -fPICLD_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;voidgdk_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. 通过以下命令安装C\C++编译环境和gtk libgtk2.0-dev。

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

3. 执行以下命令编译共享库。执行该命令时需要在sublime-imfix.c文件所在的目录。

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

4. 将编译好的库移到Sublime Text的安装目录。如果你是通过Sublime Text官网直接下载.deb文件并安装的,在我机器上的默认位置是/opt/sublime_text

mv libsublime-imfix.so /opt/sublime_text

注意执行上述命令时需要在sublime-imfix.c文件所在的目录。

5. 通过下面的命令启动Sublime Text编辑器,看看是否可以输入中文啦?

LD_PRELOAD=./libsublime-imfix.so ./sublime_text

6. 你当然不想每次都在终端通过输入命令来打开Sublime Text编辑器,切换到/usr/share/applications目录,编辑sublime_text.desktop文件的内容如下。

cd /usr/share/applications/

[Desktop Entry]Version=1.0Type=ApplicationName=Sublime TextGenericName=Text EditorComment=Sophisticated text editor for code, markup and prose#Exec=/opt/sublime_text/sublime_text %FExec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text"Terminal=falseMimeType=text/plain;Icon=sublime-textCategories=TextEditor;Development;StartupNotify=trueActions=Window;Document;[Desktop Action Window]Name=New WindowExec=/opt/sublime_text/sublime_text -nOnlyShowIn=Unity;[Desktop Action Document]Name=New FileExec=/opt/sublime_text/sublime_text --command new_fileOnlyShowIn=Unity;

注意看上面高亮的部分,将第5步中的启动命令替换进去,注意相对路径的位置。

7. 然后就没有然后了。在dash或启动栏中直接点击Sublime Text的图标,在打开的窗口中新建一个文件,切换输入法输入中文吧!
