解决Ubuntu下Sublime Text不能输入中文的问题
安装Ubuntu之后发现神器Sublime Text不能输入中文了，虽说写代码不要中文，但是写注释还有MD还是需要的嘛～
查找了下资料，解决了问题，老规矩，记录下。
1.首先将一下代码写入名为sublime-imfix.c的文件(这里假设当前目录为home（～）)
/*
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;
}

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++编译环境和gtk libgtk2.0-dev
终端下输入以下命令：
sudo apt-get install build-essential libgtk2.0-dev
3.编译共享库
终端下输入以下命令：
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
该命令需要在 home 目录下执行， 即 sublime-imfix.c 所在目录。
4.将libsublime-imfix.so拷贝到sublime_text所在文件夹
sudo mv libsublime-imfix.so /opt/sublime_text/
5.修改文件/usr/bin/subl的内容
sudo gedit /usr/bin/subl
将
#!/bin/sh exec /opt/sublime_text/sublime_text "$@"
改为
#!/bin/sh LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@"
此时，在命令中执行 subl 将可以中文输入
6.为了使用鼠标右键打开文件时或者点击快捷图标能够使用中文输入，还需要修改文件sublime_text.desktop的内容。
命令
sudo gedit /usr/share/applications/sublime_text.desktop
将[Desktop Entry]中的字符串
Exec=/opt/sublime_text/sublime_text %F
修改为
Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text -n"
将[Desktop Action Window]中的字符串
Exec=/opt/sublime_text/sublime_text -n
#修改为： Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text -n"
将[Desktop Action Document]中的字符串
Exec=/opt/sublime_text/sublime_text --command new_file #修改为 Exec=bash -c "LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text --command new_file"
注意：
修改时请注意双引号””,否则会导致不能打开带有空格文件名的文件。
此处仅修改了/usr/share/applications/sublime-text.desktop，但可以正常使用了。
opt/sublime_text/目录下的sublime-text.desktop可以修改，也可不修改。
