go语言编写脚本，开源一个全面高效

一飞开源，介绍创意、新奇、有趣、实用的免费开源应用、系统、软件、硬件及技术，一个探索、发现、分享、使用与互动交流的开源技术社区平台。致力于打造活力开源社区，共建开源新生态！

lancet（柳叶刀）是一个全面、高效、可复用的go语言工具函数库。 lancet受到了java apache common包和lodash.js的启发。

使用MIT开源协议

• 全面、高效、可复用
• 300 常用go工具函数，支持string、slice、datetime、net、crypt...
• 只依赖go标准库
• 所有导出函数单元测试覆盖率100%

1. 对于使用go1.18及以上的用户，建议安装v2.x.x。 因为v2.x.x用go1.18的泛型重写了大部分函数。

go get github.com/duke-git/lancet/v2 //安装v2最新版本v2.x.x

2. 使用go1.18以下版本的用户，必须安装v1.x.x。目前最新的v1版本是v1.2.9。

go get github.com/duke-git/lancet@v1.2.9 // 使用go1.18以下版本, 必须安装v1.x.x版本

lancet是以包的结构组织代码的，使用时需要导入相应的包名。例如：如果使用字符串相关函数，需要导入strutil包:

import "github.com/duke-git/lancet/v2/strutil"

此处以字符串工具函数ReverseStr（逆序字符串）为例，需要导入strutil包:

package main import ( "fmt" "github.com/duke-git/lancet/v2/strutil" ) func main() { s := "hello" rs := strutil.ReverseStr(s) fmt.Println(rs) //olleh }
