GoFrame gregex-基本使用

一个简单示例：

package main

import (
	"fmt"
	"github.com/gogf/gf/v2/text/gregex"
)

func main() {
	match, _ := gregex.MatchString(`(\w+).+\-\-\s*(.+)`, `GF is best! -- John`)
	fmt.Printf(`%s says "%s" is the one he loves!`, match[2], match[1])
}

执行后，输出结果为：

John says "GF" is the one he loves!
