rlox

Rust implementations of the jlox and clox interpreters from the book Crafting Interpreters.

jlox is a tree-walk interpreter written in Java and clox is a bytecode interpreter written in C.

Rust implementation of the clox interpreter from the third chapter of "Crafting Interpreters".

Note

The foundation of rclox was inspired by jeschkies's lox-rs implementation.
