## install

```
go get github.com/kurehajime/flagstone
```

## usage

1. Use golang's standard flag package.

```
    package main

import (
        "flag"
        "fmt"
    )

var who *string

func main() {
        who = flag.String("who", "world", "say hello to ...")
        flag.Parse()

fmt.Println("hello " + *who + "!")
    }
    ```

1. Import flagstone and add one line.

```
    package main

import (
        "flag"
        "github.com/kurehajime/flagstone" //★ here ★
        "fmt"
    )

var who *string

func main() {
        who = flag.String("who", "world", "say hello to ...")
        flag.Parse()

flagstone.Launch("helloworld", "flagstone sample") //★ here ★

fmt.Println("hello " + *who + "!")
    }

```

1. Finish!

When you run the program, the browser starts.

Pressing the "Run" button sets the flag and runs the program.
