Lancet is a comprehensive, efficient, and reusable util function library of go. Inspired by the java apache common package and lodash.js.
English | [็ฎไฝไธญๆ](./README_zh-CN.md)
## Feature
- ๐ Comprehensive, efficient and reusable.
- ๐ช 400+ go util functions, support string, slice, datetime, net, crypt...
- ๐
Only depend on the go standard library.
- ๐ Unit test for every exported function.
## Installation
```go
go get github.com/duke-git/lancet
```
## 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,import the strutil package like below:
```go
import "github.com/duke-git/lancet/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/strutil"
)
func main() {
s := "hello"
rs := strutil.Reverse(s)
fmt.Println(rs) //olleh
}
```
