Rumle.Golang

A small POC project where i try implementing Golang features in C#.

This is just something that I have put togehter after reading a bit about Go, not something that I would use in a real production environment. Each "goroutine" runs in its own background thread.

Features:

• chan : Rumle.Golang.Channel<T>
• select: Rumle.Golang.Select
• go: Rumle.Golang.Go.Run(Action func)

The following code will run and produce the same output as the examples that they are based on.

chan example

The following peace of C# code is based on Sameer Ajmanis ping-pong example from his Advanced Go Concurrency Patterns talk:

class Program
{
    class Ball
    {
        public int Hits { get; set; }
    }

    static void Main(string[] args)
    {
        var table = new Channel<Ball>();
        Go.Run(() => Player("ping", table));
        Go.Run(() => Player("pong", table));
        table.Send(new Ball());
        Thread.Sleep(1000);
        table.Receive();
    }
    
    static void Player(string name, Channel<Ball> table)
    {
        while (true)
        {
            var ball = table.Receive();
            ball.Hits++;
            Console.WriteLine(name + " " + ball.Hits);
            Thread.Sleep(100);
            table.Send(ball);
        }
    }
}

select example

The follow C# code is based on an example by @mmcgrana

class Program
{
    static void Main(string[] args)
    {
        var c1 = new Channel<string>();
        var c2 = new Channel<string>();

        Go.Run(() =>
            {
                Thread.Sleep(1000);
                c1.Send("one");
            });

        Go.Run(() =>
            {
                Thread.Sleep(2000);
                c1.Send("two");
            });

        for (int i = 0; i < 2; i++)
        {
            Go.Select()
              .Case(c1, _ => Console.WriteLine("received " + _))
              .Case(c2, _ => Console.WriteLine("received " + _))
              .Run();
        }
    }
}
