问题描述
在ubuntu下想使用sublime，但是不能输入中文，很尴尬啊，参考了一位中国大神的方法，再针对自己实际情况修改，成功了，哈哈。
使用环境
Ubunt Kylin 14.04, sublime text 2, 搜狗输入法。
解决方法
1. 保存下面的代码为sublime_imfix.c
1 /* 2 sublime-imfix.c 3 Use LD_PRELOAD to interpose some function to fix sublime input method support for linux. 4 By Cjacker Huang <jianzhong.huang at i-soft.com.cn> 5 6 gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC 7 LD_PRELOAD=./libsublime-imfix.so sublime_text 8 */ 9 #include <gtk/gtk.h> 10 #include <gdk/gdkx.h> 11 typedef GdkSegment GdkRegionBox; 12 13 struct _GdkRegion 14 { 15 long size; 16 long numRects; 17 GdkRegionBox *rects; 18 GdkRegionBox extents; 19 }; 20 21 GtkIMContext *local_context; 22 23 void 24 gdk_region_get_clipbox (const GdkRegion *region, 25 GdkRectangle *rectangle) 26 { 27 g_return_if_fail (region != NULL); 28 g_return_if_fail (rectangle != NULL); 29 30 rectangle->x = region->extents.x1; 31 rectangle->y = region->extents.y1; 32 rectangle->width = region->extents.x2 - region->extents.x1; 33 rectangle->height = region->extents.y2 - region->extents.y1; 34 GdkRectangle rect; 35 rect.x = rectangle->x; 36 rect.y = rectangle->y; 37 rect.width = 0; 38 rect.height = rectangle->height; 39 //The caret width is 2; 40 //Maybe sometimes we will make a mistake, but for most of the time, it should be the caret. 41 if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) { 42 gtk_im_context_set_cursor_location(local_context, rectangle); 43 } 44 } 45 46 //this is needed, for example, if you input something in file dialog and return back the edit area 47 //context will lost, so here we set it again. 48 49 static GdkFilterReturn event_filter (GdkXEvent *xevent, GdkEvent *event, gpointer im_context) 50 { 51 XEvent *xev = (XEvent *)xevent; 52 if(xev->type == KeyRelease && GTK_IS_IM_CONTEXT(im_context)) { 53 GdkWindow * win = g_object_get_data(G_OBJECT(im_context),"window"); 54 if(GDK_IS_WINDOW(win)) 55 gtk_im_context_set_client_window(im_context, win); 56 } 57 return GDK_FILTER_CONTINUE; 58 } 59 60 void gtk_im_context_set_client_window (GtkIMContext *context, 61 GdkWindow *window) 62 { 63 GtkIMContextClass *klass; 64 g_return_if_fail (GTK_IS_IM_CONTEXT (context)); 65 klass = GTK_IM_CONTEXT_GET_CLASS (context); 66 if (klass->set_client_window) 67 klass->set_client_window (context, window); 68 69 if(!GDK_IS_WINDOW (window)) 70 return; 71 g_object_set_data(G_OBJECT(context),"window",window); 72 int width = gdk_window_get_width(window); 73 int height = gdk_window_get_height(window); 74 if(width != 0 && height !=0) { 75 gtk_im_context_focus_in(context); 76 local_context = context; 77 } 78 gdk_window_add_filter (window, event_filter, context); 79 }
2. 编译动态库：
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
编译之前请确保检查一下gtk+-2.0库是否具备：
pkg-config --libs --cflags gtk+-2.0
如果提示有库找不到，自己安装一下：
sudo apt-get install gtk+-2.0
3.设置LD_PRELAD路径
让每次启动编辑器前，先把刚才编译的库加载。因为不想每次启动编辑器都打长长的命令，所以我使用如下脚本来启动：
1 #!/bin/bash 2 SUBLIME_HOME="/opt/SublimeText2" 3 LD_LIB=$SUBLIME_HOME/libsublime-imfix.so 4 EXE=$SUBLIME_HOME/sublime_text 5 bash -c "LD_PRELOAD=$LD_LIB $EXE $@"
为了启动更加方便，可以把脚本取名为sublime，放在自己的PATH环境下，就可以随时输入sublime启动编辑器了，不错吧！
4.要注意的问题
启动脚本的SUBLIME_HOME的路径中不能有空格，否则编辑器启动后还是不能输入中文；如果编辑器的路径确实有空格，可以做个软链接，这样在脚本中可以避免带空格了。
