# rlox

`rlox` is an unpronouncable variant of the tree-walk interpreter laid out in
[Crafting Interpreters](http://craftinginterpreters.com/), 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.
