R2D2 - The programming Language

R2D2 is a programming language designed for building modular JavaScript applications using a clear, explicit, and structured syntax.

It is written in Go and compiles to JavaScript, embracing a module-based architecture where each module can contain variables and functions. These modules are compiled into native JavaScript objects, making it easy to integrate with existing frontend or backend projects.

R2D2 introduces the concept of pseudo-functions — a special type of function that can only contain calls to other functions. This enforces composability and encourages building code through reusable, isolated behaviors.

The language is built with simplicity and clarity in mind. It avoids hidden behavior and favors explicit patterns, making it approachable for those who want to write structured, maintainable code that compiles directly to JavaScript.

You can start using R2D2 by executing the following command on your system.

For UNIX based systems

curl -sSL https://raw.githubusercontent.com/ArturC03/r2d2-cli/main/install.sh | bash

For Windows

Just use WSL, believe me. I'm doing you a favor.

To verify the installation, try executing r2d2, if it returns something you're good to go!

Hello World

Let's try to make a hello world program!

1. Create a .r2d2 file such as helloworld.r2d2
2. Put the following content in the file

module HelloWorld {
  export fn main() {
    console.log("Hello World!");
  }
}

1. Now you can choose to compile, run or even convert it into a js file by using on of the following commands

r2d2 build helloworld.r2d2

r2d2 run helloworld.r2d2

r2d2 js helloworld.r2d2
