rlox

rlox is an unpronouncable variant of the tree-walk interpreter laid out in Crafting Interpreters, written in Ruby, because I want to learn it.

It deviates a little from the “canonical” version of Lox. I don’t use code generation for the expressions, and I don’t use the visitor pattern. var and fun are let and fn, respectively. And we don’t need parentheses around branching conditions, instead we require the bodies to be blocks.
