Re: actors library?

[xancorreu]

Thanks Gehr for your examples. Very illustrative.
I wanted what you do in example 1 like a library. It's easy import 
actors library than to define your own actors (class).

Thanks,
Xan.

Xan, read this article please:

You have exactly what you are looking for in the D runtime and
standard library.
I read it and **after** I post the question. I don't know how
std.concurrency is related to actors model. Can you enlight me?

Thanks,
Xan.

std.concurrency is an implementation of the actor model.
'Actor model' does not imply 'Object Oriented'.

Example 1:

import std.stdio, std.concurrency;
void myActor() {
    try {
        for(;;){
            receive(
                (int i){ writeln("Received integer: ",i); }
            );
        }
    }catch(Exception e){
        // cleanup
    }
}

void main() {
    auto actor = spawn(&myActor);
    foreach(i;0..10) actor.send(i);
}

Example 2:

import std.stdio, std.concurrency;
import core.thread;
alias Thread.sleep sleep;
void ping() {
    Tid pong;
    try {
        for(;;){
            receive(
                (string s){
                    writeln("ping received ",s);
                    sleep(dur!"seconds"(1));
                    pong.send("ping");
                },
                (Tid newPong){ pong = newPong; }
            );
        }
    }catch(Exception e){}
}

void pong(Tid ping) {
    try {
        ping.send("pong");
        for(;;){
            receive(
                (string s){
                    writeln("pong received ",s);
                    sleep(dur!"seconds"(1));
                    ping.send("pong");
                }
            );
        }
    }catch(Exception e){}
}

void main() {
    auto a1 = spawn(&ping);
    auto a2 = spawn(&pong,a1);
    a1.send(a2);
    sleep(dur!"seconds"(10));
}
