Rust implemention of the Lox bytecode intepreter in Crafting Interpreters

Rustilocks

Work in progress implemention of the Lox bytecode intepreter in Robert Nystrom's book Crafting Interpreters.

This is a Rust binary crate built with the clap CLI library, so cargo run help will print useful things. The binary operates on 3 file formats:

• .lox: Lox source code.

• .loxa: Lox assembly. This is similar to the disassembly output in Crafting Interpreters except it can also be parsed back in and compiled to bytecode.

• .rlks: Lox binary code. This is a serialization of a compiled Lox program, and can be run directly by the Rustilocks interpreter.

Goals

• Fully implement the interpreter to really understand how such interpreters work.

• Gain more experience with Rust.

Non-goals

• Performance; prefer to use simple idiomatic Rust.

• Implementing hash maps, stacks, etc. by hand, as is done in the book; instead, use the Rust standard library.

Status

• Chapter 14-21: done

• Chapter 22: in progress.

• Chapter 24-29: to be started
