ubuntu下解决sublime2中文输入问题

1. 安装 fcitx输入框架

sudo add-apt-repository ppa:fcitx-team/nightly

sudo apt-get update

sudo apt-get install fcitx-sogoupinyin

2. 编译共享内存

1) 保存如下代码到任意目录,将其命名为 sublime-imfix.c

/*
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) 安装C/C++的编译环境和gtk libgtk2.0-dev

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

3) 编译共享内存

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

4) 现在就可以在当前目录下运行一下命令启动sublime2,实现中文输入了

LD_PRELOAD=./libsublime-imfix.so sublim

3.创建快捷方式

1)将编译目录下的 libsublime-imfix.so 拷贝到 /usr/lib 目录下

2)在 /usr/share/applications 目录下新建一个名为 sublime2.desktop 的文件,其内容如下:

[Desktop Entry]
Name=Sublime
Comment=sublime
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /usr/bin/sublime' %F
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /usr/bin/sublime' --new-window
Icon=/home/tbin/Software/sublime2/Sublime.png
Terminal=false
Type=Application
Categories=Application;Development

3)这样就可以在applications中找到sublime的快捷方式了.
