获取

go get -u github.com/Li-giegie/go-scout

使用

package main

	"fmt"
	go_scout "github.com/Li-giegie/go-scout"
	"log"
	"os"
)

//type ScoutI interface {
// Root() string                              //目录路径
// StartEvent(info []*FileInfo)               //首次启动后触发检测目录的文件信息
// CreateEvent(info []*FileInfo)              //检测到创建行为触发
// ChangeEvent(info []*FileInfo)              //检测到有变更行为触发
// RemoveEvent(info []*FileInfo)              //检测到有删除行为触发
// ErrorCallBack(err error) (isContinue bool) //isContinue：是否继续，true继续，false遇到错误终止
//}
