rlox

Lox bytecode compiler and interpreter written in Rust.

My implementation has a few QoL improvements over the vanilla language:

• nil -> null
• fun -> fn
• var -> let
• +=, -=, *=, and /= for operation and assignment
• % for modulo
• break support inside for and while loops
• print as a built-in function instead of a statement

Some possible optimizations to implement once everything is up and running so I can measure them:

• Use tries for matching keywords (https://docs.rs/trie-match/latest/trie_match/)
• Sprinkle some pointer + unsafe magic around
• Use data structures that go more brrr (FxHash{Set, Map}, ArrayVec...)
