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. 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.
