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。
简体中文 | [English](./README.md)
## 特性
- 👏 全面、高效、可复用
- 💪 400+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%
## 安装
```go
go get github.com/duke-git/lancet
```
## 用法
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:
```go
import "github.com/duke-git/lancet/strutil"
```
## 例子
此处以字符串工具函数 Reverse（逆序字符串）为例，需要导入 strutil 包:
```go
package main
import (
"fmt"
"github.com/duke-git/lancet/strutil"
)
func main() {
s := "hello"
rs := strutil.Reverse(s)
fmt.Println(rs) //olleh
}
```
