What Radon Includes Today

The current repository ships with:

• An interactive REPL in radon.py
• File execution with python radon.py program.rn
• Inline execution with python radon.py -c 'print("hello")'
• Dynamic types including numbers, strings, booleans, arrays, hash maps, and null
• Functions, classes, methods, modules, and from ... import ... support
• A Radon standard library in stdlib/
• A Python bridge through pyapi() with runtime permission prompts

First Run

git clone https://github.com/radon-project/radon.git
cd radon
python radon.py

To run a file instead of the REPL:

python radon.py examples/simple.rn

Example

import io

class Network {
    fun __constructor__(username, password) {
        this.username = username
        this.password = password
    }

    fun login() {
        if this.username == "radon" {
            if this.password == "password" {
                print("Log in successful")
            } else {
                print("Invalid credentials")
            }
        } else {
            print("Invalid credentials")
        }
    }
}

var username = input("Enter your username: ")
var password = io.Input.get_password("Enter your password: ")

var network = Network(username, password)
network.login()

Notes on Permissions

Some capabilities delegate to Python or the host system. When a program uses the Python API, disk access, or network access, Radon can prompt before continuing. The CLI also exposes testing-only flags such as --allow-py, --allow-disk, and --allow-network.
