安装fcitx输入法

这个看前面教程

编译sublime-imfix.so

/*

#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);
}

保存后，编译之：

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

然后放到sublime_text_3的安装目录下。

配置环境变量

我曾经尝试在~/.bashrc或者~/.bash_profile中定义相应的变量，确实可以输入中文，但重启并输入登录密码后，无法进入桌面，所以还是写到脚本里好了：

新建名为sublime_text_run的脚本，添加：

#!/bin/bash
export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS="@im=fcitx"

export LD_PRELOAD="/home/chris/software/sublime_text_3/libsublime-imfix.so"

其中，前三个是用来调用fcitx的;最后一个是指定前面编译出的.so文件的路径，应当根据实际情况修改。

保存后，为此脚本创建软链接，比如链接到/usr/bin/目录。或者直接移动到/usr/bin也可以。

好了， 现在可以通过sublime_text_run的命令召唤出sublime_text，并流畅地使用fcitx输入中文了！
