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。
|
||
</p>
|
||
|
||
简体中文 | [English](./README.md)
|
||
|
||
## 特性
|
||
|
||
- 👏 全面、高效、可复用。
|
||
- 💪 500+常用 go 工具函数,支持 string、slice、datetime、net、crypt...
|
||
- 💅 只依赖 go 标准库和 golang.org/x。
|
||
- 🌍 所有导出函数单元测试覆盖率 100%。
|
||
|
||
## 安装
|
||
|
||
### Note:
|
||
|
||
1. <b>使用 go1.18 及以上版本的用户,建议安装 v2.x.x。 因为 v2.x.x 应用 go1.18 的泛型重写了大部分函数。</b>
|
||
|
||
```go
|
||
go get github.com/duke-git/lancet/v2 //安装v2最新版本v2.x.x
|
||
```
|
||
|
||
2. <b>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 v1.4.0。</b>
|
||
|
||
```go
|
||
go get github.com/duke-git/lancet// 使用go1.18以下版本, 必须安装v1.x.x版本
|
||
```
|
||
|
||
## 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/v2/strutil"
|
||
```
|
||
|
||
## 示例
|
||
|
||
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/v2/strutil"
|
||
)
|
||
|
||
func main() {
|
||
s := "hello"
|
||
rs := strutil.Reverse(s)
|
||
fmt.Println(rs) //olleh
|
||
}
|
||
```
|
||
|
||
