Python implementation of JLox

Lox compiler in Python

This Lox compiler is an implementation of the book “Crafting Interpreters” from Bob Nystrom. It is not delivered as a complete package to let you play with it as you like.

Requirements

The code uses Python 3.6 and was developed on OS X. It should work quite easily on Windows.

How to run the lox compiler

1. You can run the REPL with “python3 -m lox.lox” once you are in the pylox folder (top folder). You can exit the REPL with ‘exit’.
2. You can run any test file (extension does not matter) as “python3 -m test.test_lox testfiles/$file”, placing the file in “test/testfiles” folder.

What is implemented on top of the book (in the Challenges section)

1. ‘break’ statement is implemented.
2. Closures are implemented.
3. Lambdas are implemented (lambdas are supposed to be anonymous function here).

pylox's Issues

Hello

Hi! It looks impressive, a lot of things implemented. Is that everything what was in the book or have you added something more?
I'd like to read the CI book as well, so I've checked python implementations from that page: https://github.com/munificent/craftinginterpreters/wiki/Lox-implementations
Great job. Hope that I would be able to refer to that repo in case I'm stuck.
Thanks!
