Welcome to Kaon

A little scripting language written in rust.

Examples

Hello World

A simple hello world program:

System.println("Hello, World!")

Classes

A slightly more convoluted example using classes:

class Vector {
    // A field
    var x = 0
    var y = 0

    // A constructor
    create new(a, b) {
        self.x = a
        self.y = b
    } 

    fun add(other: Vector) {
        self.x = self.x + other.x
        self.y = self.y + other.y
    }

    // A method
    fun to_string() {
        return "{ x: " + self.x + " y: " + self.y + " }"  
    }
}

fun main() {
    var v1 = Vector.new(4, 5)
    var v2 = Vector.new(6, 7)

    v1.add(v2)

    print(v1.to_string()) // -> { x: 10 y: 12 }
}

main()

More examples can be found in scripts or tests/kaon.

Features

Object-oriented

Bytecode compiler and VM

Simple, straightforward syntax

Strongly typed; the compiler does its best to eliminate runtime errors

Getting Started

To get started using kaon, first make sure you have cargo installed, then run the following commands:

git clone https://github.com/PlutonianHacker/kaon-lang.git
cd kaon-lang
cargo build

Usage

Currently the only way to run a Kaon script is with cargo run inside the kaon-lang directory. To run a file, use cargo run <FILE.kaon>, if no file is provided, interactive mode is run instead. To see a list of options, run cargo run -- --help.

Contributing

All contributions are welcome! If you find any bugs or have ideas to make the language better, you can open up an issue.
