example

参照php的date()函数和strtotime()函数

t := utils.StrToTime("2012-11-12 23:32:01")

字符串转换为time.Time类型

t := utils.StrToLocalTime("2012-11-12 23:32:01")
t := utils.StrToLocalTime("2012-11-12")

原生Go实现字符串转换为time.Time类型

t := time.Date(2012, 11, 12, 23, 32, 01, 0, time.Local)
t := time.Date(2012, 11, 12, 0, 0, 0, 0, time.Local)

time.Time类型格式化为字符串

now := time.Now()
strTime := utils.Format("Y-m-d H:i:s", now)

原生Go实现time.Time类型格式化为字符串

strTime := time.Now().Format("2006-01-02 15:04:05")

Overview

Package functools is a simple Golang library including some commonly used functional programming tools. There is no generic in golang, so most of the functions will return interface{}, be sure to type assert it to the type you want before you use it.
