在Ubuntu 14.04中使SublimeText 3支持中文输入法(搜狗)
在Ubuntu 14.04中安装了SublimeText 3 以及搜狗输入法linux
发现SublimeText输入不了中文
解决办法如下：
安装C/C++的编译环境和gtk libgtk2.0-dev 命令如下
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
sudo apt-get install gtk+-2.0
创建sublime_imfix.c文件，可以放在当前用户目录～下，内容如下：
/*
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);
}
然后编译成共享库
gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
在目录下，得到libsublime-imfix.so
命令行启动sublime，检测一下能否输入中文：
LD_PRELOAD=./libsublime-imfix.so subl
假如成功，就可以输入中文了。
接下来我们还要通过修改sublime_text.desktop达到点击图标启动，也可以输入中文。
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sublime_text.desktop
cd /usr/share/applications
sudo gedit sublime_text.desktop
打开sublime_text.desktop后，修改如下
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
