I'm in the process of rewriting the language from typescript to nim, so right now it's a recursive descent parser written in typescript[1]. Typescript generates the textual bytecode and that feeds into a Nim interpreter.[2]

I think I'll keep the recursive descent parser even after rewriting to Nim. It's easy to change the grammar and understand how it works, and I can have good error messages & handling.

IMO the main problem is that right now the code for parsing infix expressions is fairly repetitive, I'd like to eventually use Pratt parsing for that.
