一个简单示例：

package main

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

func main() {
    match, _ := gregex.MatchString(`(\w+).+\-\-\s*(.+)`, `GoFrame 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 "GoFrame" is the one he loves!
