在Ubuntu 14.04中使SublimeText 3支持中文输入法

在Ubuntu 14.04中安装了SublimeText 3之后发现既然不支持输入中文，于是在网上搜罗一下，发现很多人遇到了同样的问题，但是解决办法大该就只有一个。下面根据自身的安装及解决办法总结如下：

1. SublimeText 3的安装

Ubuntu14.04

搜狗输入法 for Linux

Sublime text 3

2.拷贝如下代码到文件sublime-imfix.c文件中，该文件需要自己创建，随便放到那里都行。

/*
* 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);
}
3.编译

按照文件头上注释所说的编译该文件，在终端里进入到存放该文件的目录中，输入如下命令：
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC

最后在当前目录下得到libsublime-imfix.so这个共享库。
4. 鼠标右键打开支持中文

在这里提供简单修改图标连接的方式，快速打开SublimeText。将libsublime-imfix.so拷贝到系统库的默认路径中：

sudo cp libsublime-imfix.so /usr/lib/

修改/usr/share/applications/sublime_text.desktop文件

sudo vim /usr/share/applications/sublime_text.desktop

打开后将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

这样就通过快捷方式打开SublimeText 3就可以支持中文输入了。
5.命令行打开支持中文

修改文件/usr/bin/subl的内容 sudo gedit /usr/bin/subl 将 #!/bin/sh exec /opt/sublime_text/sublime_text "$@" 修改为 #!/bin/sh LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so exec /opt/sublime_text/sublime_text "$@" 此时，在命令中执行 subl 将可以使用搜狗for linux的中文输入
