# Installation
|
||||
|
||||
1. <b>For users who use go1.18 and above, it is recommended to install lancet v2.x.x. Cause in v2.x.x all functions was rewriten with generics of go1.18.</b>
|
||||
|
||||
```go
|
||||
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. The latest of v1.x.x is v1.4.1. </b>
|
||||
|
||||
```go
|
||||
go get github.com/duke-git/lancet // below go1.18, install latest version of v1.x.x
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
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, just import the strutil package like below:
|
||||
|
||||
```go
|
||||
import "github.com/duke-git/lancet/v2/strutil"
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
Here takes the string function `Reverse` (reverse order string) as an example, and the strutil package needs to be imported.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"github.com/duke-git/lancet/v2/strutil"
|
||||
)
|
||||
|
||||
func main() {
|
||||
s := "hello"
|
||||
rs := strutil.Reverse(s)
|
||||
fmt.Println(rs) //olleh
|
||||
}
|
||||
```
|
||||
|
||||

||||

# What is lancet?
|
||||
|
||||
<b>Lancet is a powerful, efficient, and reusable util function library of go. Inspired by the java apache common package and lodash.js. </b>
|
||||
|
||||
|
||||
## Why lancet?
|
||||
|
||||
Lancet makes Go dev easier by taking the hassle out of working with concurrency, net, math, slice, string, etc.
|
||||
Lancet's utility methods are great for:
|
||||
|
||||
- Iterating slice and array.
|
||||
- Manipulating strings.
|
||||
- Work with net and http.
|
||||
- Other tools, eg. random, crypto, stream, retry, etc.

# 安装
|
||||
|
||||
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 // will install latest version of 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 v1.4.1。</b>
|
||||
|
||||
```go
|
||||
go get github.com/duke-git/lancet // below go1.18, install latest version of v1.x.x
|
||||
```
|
||||
|
||||
## 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
|
||||
}
|
||||
```
|
||||
|
||||

# lancet是什么?
|
||||
|
||||
<b>lancet（柳叶刀）是一个强大、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。 </b>
|
||||
|
||||

|
||||
|
||||
- 迭代切片和数组。
|
||||
- 操作字符串。
|
||||
