多关键字的文本精确匹配搜索 (mss - Multi-String Search)

基本的要求是对给定的一个文本块进行关键字匹配，进行匹配的关键字是多个，而且可能非常多(成千上万)，然后输出各个匹配到的关键字的位置。这可用用作关键字的高亮显示，当然也可用进行敏感词过滤。

参考linux命令行fgrep

输入一段文本，输出匹配到的关键字在输入文本中的位置。

例如，关键词列表：

	package xsync

	import (
	"context"
	"fmt"
	"runtime/debug"
	)

	// PanicGroup 并行执行多个协程并捕获所有 panic
	// 使用方法如下

	env YACC=`brew --prefix bison`/bin/bison ./configure
	--disable-all
	--prefix=/tmp/php71
	--enable-phar
	--enable-zip
	--enable-tokenizer
	--enable-json
	--enable-posix
	--with-libedit

	// compile with: gcc epoll-example-pipe.c

	#include <stdio.h>
	#include <stdlib.h>
	#include <sys/epoll.h>

	#define MAXEVENTS 64

	int
	main (int argc, char *argv[])

	#!/usr/bin/env php

	# you should add the following two line in you ovpn.conf
	# route-noexec # donot let openvpn set local route
	# route-up a.sh # run a.sh under ~/Library/Application Support/Tunnelblick/Configurations/bilibili.tblk/Contents/Resources

	<?php
	$env = $_ENV;

	$route = [];

	# -- coding: utf-8 --
	import socket

	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM);
	s.connect(('192.168.8.20', 3000))

	m = '{"username":"test20","message":"测试"}'
	mp = (
	"POST /notice HTTP/1.0\r\n"
	"Content-Type:application/json\r\n"

	# curl -H "Content-Type: application/json" -d '{"username":"test20","message":"测试"}' http://192.168.8.20:3000/notice -v

	#include <stdio.h>

	void doit(char *text)
	{
	char out;cJSON json;

	json=cJSON_Parse(text);
	if (!json) {printf("Error before: [%s]\n",cJSON_GetErrorPtr());}
