### Note:
|

1. <b>For users who use go1.18 and above, it is recommended to install lancet v2.x.x. Cause v2.x.x rewrite all functions with generics of go1.18.</b>
|

```go
|

go get github.com/duke-git/lancet
|
||||
go get github.com/duke-git/lancet/v2 // will install latest version of v2.x.x
|

```
|

|
||||
2. <b>For users who use version below go1.18, you should install v1.x.x. now latest v1 is v1.2.9. </b>
|
||||
```go
|
||||
go get github.com/duke-git/lancet@v1.2.9 // below go1.18, install latest version of v1.x.x

Lancet organizes the code into package structure, and you need to import the corresponding package name when use it. For example, if you use string-related functions,import the strutil package like below:
|
||||
|
||||
```go
|
||||
import "github.com/duke-git/lancet/strutil"
|

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

## 安装
|
||||
### Note:
|
||||
1. <b>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。</b>
|
||||
|
||||
```go
|
||||
go get github.com/duke-git/lancet
|
||||
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v1.2.9。</b>
|
||||
```go
|
||||
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
|
||||
```
|
||||
|
||||
## 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:
