Linux教程:在Ubuntu14.04中使SublimeText3支持中文输入法
在Ubuntu 14.04中安装了Sublime Text 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
安装方式有多种,本文所描述的是从官方网站上下载64位的.deb文件 ,具体为http://c758482.r82.cf2.rackcdn.com/sublime-text_build-3059_amd64.deb 文件,下载后双击即会自动使用默认的安装软件安装。
2. 相关依赖软件的安装
sudo apt-get install build-essential libgtk2.0-dev
3. 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
*
* gcc -shared -o libsublime-imfix.so sublime_imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
* LD_PRELOAD=./libsublime-imfix.so sublime_text

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);
}
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. 中文输入
到这里默认已经装好了中文输入法(搜狗输入法linux版)。得到第3步中的库libsublime-imfix.so之后,先试试看是否能正常使用中文输入法,在终端中输入如下命令:
LD_PRELOAD=./libsublime-imfix.so subl #subl是安装好SublimeText 3后的程序启动命令
如果一切正常,在启动之后,搜狗输入法就能可以输入了。
5. 为了方便
在第4步中如果每次都输入LD_PRELOAD这样显得太不方便了,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。
注:第五步仅限使用.deb文件安装的情况,如果使用源码安装的则需要变通一下,写个脚本将LD_PRELOAD加上即可
