The first implementation of the educational Lox language in the book Crafting intepreters (https://craftinginterpreters.com) is done in Java. As an excercise, I did it in Ruby instead.
While doing that I did my best to follow the naming and style convetions from the book which is why the code sometimes looks a bit like Java, not Ruby. This is for pragmatic reasons: to make it easier to find the relevant part in the book when looking at the code.
The implementation is now complete, all of the language features from the book are implemented.
Clone the repo and install the gems with bundle.
After that you can use bin/run in 2 different ways:
bin/runwithout arguments will run an interactive console that will evaluate Lox commands. Beware that you'll need to useprintto see the output.bin/run [script]will run a lox script. There are several in examples folder, for examplebin/run examples/fibonacci.lox
It's just a personal learning project, I expect no contributions.
