## Install

```sh

go get github.com/nasermirzaei89/env

```

## Sample Usage

### With default value

```go

package main

import (

	"fmt"

	"github.com/nasermirzaei89/env"

)

func main() {

	b := env.GetBool("A", true)

	fmt.Println(b) // true (default)

	f := env.GetFloat64("B", 14.5)

	fmt.Println(f) // 14.5 (default)

	i := env.GetInt("C", 12)

	fmt.Println(i) // 12 (default)

	s := env.GetString("B", "hi")

	fmt.Println(s) // hi (default)

	// Generics

	b2 := env.Get("A", true)

	fmt.Println(b2) // true (default)

	f2 := env.Get("B", 14.5)

	fmt.Println(f2) // 14.5 (default)

	i2 := env.Get("C", 12)

	fmt.Println(i2) // 12 (default)

	s2 := env.Get("B", "hi")

	fmt.Println(s2) // hi (default)

}

```

### Force setting environment

```go

package main

import (

	"fmt"

	"github.com/nasermirzaei89/env"

)

func main() {

	s := env.MustGetString("HOME")

	fmt.Println(s) // /Users/nasermirzaei89

	s = env.MustGetString("NEW") // panics

	// Generics

	s2 := env.MustGet[string]("HOME")

	fmt.Println(s2) // /Users/nasermirzaei89

	s2 = env.MustGet[string]("NEW") // panics

}

```
