Lox — jlox & clox

This repository contains two implementations of the Lox language from Robert Nystrom’s Crafting Interpreters:

• jlox — a tree-walking interpreter implemented in Java.
• clox — a bytecode compiler and virtual machine implemented in C.

Requirements

• Java 11+ for jlox
• C compiler (GCC, Clang, or MSVC) and CMake for clox

Learning goals

Part	Focus	Key Topics
jlox	Simplicity & clarity	Lexing, Parsing, ASTs, Interpreter, Resolver
clox	Performance & internals	Bytecode, VM loop, Stack frames, Compiler, GC
