# 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. We also have closures and anonymous functions (and literals for them), and implicit returns. If you wonder what that looks like, you can look at the [examples](/examples).
