MonkeyLang

A toolchain for the Monkey programming language on the .NET platform.
Note that this project is still under active developement.

  A CLI tool for the Monkey programming language that runs on .NET. Monkey is a general-purpose, minimal, procedural language with first-class functions. With a robust toolchain and tight .NET integration, it offers a feature rich platform with an emphasis on rapid prototyping.

 

Easy to install

dotnet tool install --global bryjen.monkey

No bootstrapping or building from source required, all you need is a compatible .NET runtime installed.

 

Development experience first

Inspired by the error handling and error messages of modern functional languages (OCaml, F#, Rust, Gleam, etc.), the toolchain is developed to make writing and debugging as stress-free and predictable as possible.

 

Dotnet Interop

// csharp interop example
let builder = WebApplication.CreateBuilder(args);
let app = builder.Build();

let middleware = async fn(HttpContext context, Func<Task> next) {
    // preprocessing
    await next();
    // postprocessing
};

app.Use(middleware);
app.Run();

With first-class .NET support, Monkey can seamlessly use countless C#/F#/VB.NET libraries. Monkey can also transpile into C#, allowing you to see how your Monkey code translates to C#.
