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.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. 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=1.0 Type=Application Name=Sublime Text GenericName=Text Editor Comment=Sophisticated text editor for code, markup and prose #Exec=/opt/sublime_text/sublime_text %F Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text" Terminal=false MimeType=text/plain; Icon=sublime-text Categories=TextEditor;Development; StartupNotify=true Actions=Window;Document; [Desktop Action Window] Name=New Window Exec=/opt/sublime_text/sublime_text -n OnlyShowIn=Unity; [Desktop Action Document] Name=New File Exec=/opt/sublime_text/sublime_text --command new_file OnlyShowIn=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！
