Ruskey 🦀

An implementation of the Monkey programming language interpreter in Rust, based on the book “Writing An Interpreter In Go” by Thorsten Ball.

About

🚧 Work In Progress 🚧

This project is currently under active development. It’s a Rust implementation of the Monkey programming language introduced in the book “Writing An Interpreter In Go”. It serves as both a learning exercise for Rust and interpreter design.

The Monkey language features:

• C-like syntax
• Variable bindings
• Integer and boolean data types
• Functions as first-class citizens
• Closures
• A simple object system
