Building

1. Install Rust and Cargo using rustup
2. Clone this repository
3. Run cargo build to build the project
4. Run cargo test to run the test suite

Usage

cargo run -- input.ls

This will compile the LavaScript source file input.ls and output JavaScript code.

Example

// Example LavaScript code
class Animal {
  init() {}
  method speak() Void { return println(0); }
}

class Cat extends Animal {
  init() { super(); }
  method speak() Void { return println(1); }
}

Animal cat;
cat = new Cat();
cat.speak();
