A little guidance. A lot to build.

Explore the ideas behind Elfie, learn the shape of the language, and find your way from intent to a first program.

New to Elfie?

Start with a small idea.

Take a tour of the core ideas of the language and what it can do. Then build your first program with a guided example.

hello.lfy

fn hello(): `Greets the world` {
  @acceptanceCriteria.add({
    behavior = `Prints "Hello world!"`,
  });
}

A tiny example to start

Core concepts

Understand the building blocks you can use to build your next piece of software.

Diving deeper

See how d, fn, and acceptance criteria turn intent into code that an agent writes and another agent checks.

Compiling code

A reference to the Elfie CLI: how to build your app, and every flag, setting, and file you need to get going.

Behind the language

Explore how a compile works and the language choices behind it.

Follow a step-by-step tutorial and build a small program from the ground up.
