# gflag

A go1.18 wrapper to provide simple generics based API for defining command line flags.

## Example

```

package main

import (

	"flag"

	"fmt"

	"time"

	"github.com/ckaznocha/gflag"

)

func main() {

	salutation := gflag.Define("salutation", "Hello", "a salutation")

	subject := gflag.Define("subject", "user", "a subject to greet")

	wait := gflag.Define("wait", 1*time.Second, "how long  to  wait before greeting")

	flag.Parse()

	time.Sleep(*wait)

	fmt.Printf("%s, %s\n", *salutation, *subject)

}

```
