`chef`

Chef is a stack-based language designed to read like a recipe

The language was created following completion of Part III of the book Crafting Interpreters, porting the C bytecode interpreter into Rust (the implementation of Lox, with classes, closures etc. can be found on the lox branch)

In creating a grammar for a recipe-oriented language, I gained deeper insights into Pratt-parsing and stack-based compilation than the first pass through the book. I have written about the interesting challenges and alterations here (TODO)

Recipe for the nth fibonacci number
