The Obligatory Hello World

This example shows how to define and consume actors in Go

Hello World using the Go API

Define a message:

//define a struct for our message
type Hello struct{ Who string }

Define your actor

func (state *HelloActor) Receive(context actor.Context) {
    switch msg := context.Message().(type) {
    case Hello:
        fmt.Printf("Hello %v\n", msg.Who)
    }
}

Usage:

func main() {
    props := actor.FromInstance(&HelloActor{})
    pid := actor.Spawn(props)
    pid.Tell(Hello{Who: "Roger"})
    console.ReadLine()
}
