🧵 Naples 🇮🇹

Naples is a simple asynchronous runtime for C#, built as a learning project inspired by the Rust library Tokio. The name is a nod to the Italian city — and to Tokio itself, which is also named after a city.

How does it work

Waker: holds a callback and fires it once when signaled, telling the scheduler a task is ready;
Scheduler: maintains a queue of tasks and runs them one by one — if a task is not completed it gets re-queued;
Runtime: the public face of the library, exposes Spawn() to add tasks and Run() to start the executor loop;
Channel<T>: a typed pipe between two tasks — one side sends values with Send(), the other receives them with TryReceive();

Example

using Naples.Core;
using Naples.Sync;

var runtime = new Runtime();
var channel = new Channel<string>();

// Task producer - sends a message
runtime.Spawn(() =>
{
    channel.Send("Hi from Naples");
    return Task.CompletedTask;
});

// Task consumer - receives a message
runtime.Spawn(() =>
{
    if (channel.TryReceive(out var message))
        Console.WriteLine(message); // "Hi from Naples!"

    return Task.CompletedTask;
});

// Runs everything
runtime.Run();

The runtime runs the loop, runs the producer, then the consumer and when the queue is empty it stops.

Requirements

Windows 10 or later
.NET SDK 10.0 or later

How to use

To add Naples as a dependency in your C# project execute this command:

dotnet add package Naples --version 1.0.0 # In the command prompt or powershell

Now in the .csproj file should appear this line:

<PackageReference Include="Naples" Version="1.0.0" />

Limitations

Single-threaded — all tasks run on one thread
Not thread-safe
No exception handling inside tasks
No I/O support (no timers, no sockets)
