CoCoL 1.8.1

CoCoL is a fresh multi-programming approach, leveraging the C# await keyword to produce sequential and easily understandable multithreading code. With a shared-nothing approach and explicit communication, programs written with CoCoL are automatically free from race conditions and other threading hazards.

If you are familiar with the Go Language, you can think of CoCoL as providing the Go programming model inside the CLR.

Hello World

The most basic program with multithreading would be a producer/consumer setup, where one thread produces data, and another consumes it:

using CoCoL;

class Example
{
    static async Task Produce(IChannel<int> channel)
    {
        foreach (var i in Enumerable.Range(0, 5))
            await channel.WriteAsync(i);
        channel.Retire();
    }

    static async Task Consume(IChannel<int> channel)
    {
        try
        {
            while (true)
                Console.WriteLine("Hello World: {0}", await channel.ReadAsync());
        }
        catch (RetiredException)
        {
        }
    }

    static void Main()
    {
        var channel = ChannelManager.CreateChannel<int>();
        Task.WhenAll(
          Produce(channel),
          Consume(channel)
        ).Wait();
    }
}

Output:

Hello World: 0
Hello World: 1
Hello World: 2
Hello World: 3
Hello World: 4
