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 + "!")
   }
   

2. Import flagstone and add one line.

   package main
   
   import (
       "flag"
       "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 + "!")
   }
   
   

3. Finish!

   When you run the program, the browser starts.

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