clox — Crafting Interpreters (clox, C)

A tiny bytecode VM + compiler for the Lox language, built while following Crafting Interpreters. This is a personal learning project.

Crafting Interpreters: https://craftinginterpreters.com/

Build

Requires a C99 compiler (tested with clang on macOS). Uses the provided Makefile.

# Build the executable to bin/clox
make

# Clean build artifacts
make clean

# Show discovered sources/objects (diagnostic)
make debug

# (Optional) regenerate compile_commands.json for clangd/etc.
make bear

Run (current behavior)

The current main builds a tiny test chunk and disassembles it—there’s no REPL or script runner yet.

./bin/clox

Example output:

== test chunk ==
0000  123 OP_CONSTANT    0 '1.2'
0002   | OP_RETURN

Layout

include/   # headers (.h files)
src/       # source (.c files)
obj/       # build objects (generated)
bin/       # executable output (generated)

Notes

• Tracks the book’s clox implementation; commits may follow chapters.
• compile_commands.json can be generated via make bear for editor tooling.
