Yet Another Lox Interpreter

Another Rust implementation of Lox, the language introduced in Crafting Interpreters by Robert Nystrom.

Tip

What makes this unique: Nothing! This Lox interpreter is just a vessel I use to learn Rust. Expect non-idiomatic and unsafe Rust here and there! Nevertheless, this might be useful to people who also follows the book with Rust.

Important

Unlike other Rust implementations out there, I don't use the Visitor pattern used in the book. It's all full on pattern matching.

Setup

  1. Install Rust
  2. REPL: cargo run
  3. Executing .lox script: cargo run -- your_script.lox

Tip

Check out playground dir. It contains some example Lox scripts. Run via cargo run -- playground/{script_name}.lox
