Crafting Interpreters

by Robert Nystrom (@munificentbob)

I worked on the 1st Print Edition. Unlike a lot of the other books worked on in this monorepo, the code doesn't follow a chapter-by-chapter structure, as it's not appropriate in this case.

This book covers off two implementations of a programming language called Lox, and each gets its own folder.

• jlox (Java Implementation)
• clox (C Implementation)

I also may complete some bonus implementations.

• pylox (Python Implementation)
• rlox (Rust Implementation)

Textbook code is available at https://github.com/munificent/craftinginterpreters/.

jlox ☕️

Usage

I have completed all of part 1 of the textbook! But I have not done any extension exercises, thus my implementation still fails dozens of the test suite tests.

You can run the jlox exe in 'repl' mode:

bazel run //books/crafting_interpreters/jlox/lox:Lox
> var foo = 12;
> print foo;
12

Or you can pass it a file:

bazel run //books/crafting_interpreters/jlox/lox:Lox -- foo.lox

Testing

Integration

I have a script that clones and use's the textbook's test suite.

./scripts/run_test.sh

---

clox

I worked on the C implementation of the Lox interpreter straight after finishing jlox. It's a bytecode interpreter using a stack-based virtual machine.

Usage

You can run the clox exe in 'repl' mode:

bazel run //books/crafting_interpreters/clox/lox

Or you can pass it a file:

bazel run //books/crafting_interpreters/clox/lox -- foo.lox

Testing

Integration

I have a script that clones and use's the textbook's test suite.

TODO(Jonathon): Support clox testing in ./scripts/run_tests.sh

---

rlox 🦀

After I've completed that C implementation, clox, I'll implement a Lox interpreter in Rust to both learn Rust better and solidify my learning from the textbook.

Usage

At the moment rlox is TODO.

You can run the rlox exe in 'repl' mode:

bazel run //books/crafting_interpreters/rlox/lox

Or you can pass it a file:
