Threading

New threads can be created with the fork keyword, which allows you to start a function in a new thread.

function spin() {
    loop {} //Loop forever.
}

fork spin()
print("This still prints!")

You can pass arguments like a normal function does, although you cannot return values. In order to communicate between threads you need to use pipes or the Mailbox system.

The MailBox system is a default pipe that connects your thread with its creator.

function sendHelloWorld() {
    outbox("Hello World")
}

fork sendHelloWorld()
print(inbox())

You can also create your own pipe.

function communicateWithMe(||channel) {
	var m = channel()
    print("You sent me: ", m)
    outbox("I sent you this")
}

var p = ||
fork communicateWithMe(p)
p("Hello thread")
print("Reply: ", inbox())
