Fast Parse VS adventofcode

Perhaps use Li Haoyi's fastparse instead? https://github.com/com-lihaoyi/fastparse

You might want to adapt Li Haoyi’s XML parser for fastparse.

Mostly a mess of pattern matching. I really need to make some generic tree utilities. Haven't been able to find a decent parser combinator that works in Scala 3 (I usually use fastparse which depends heavily on Scala 2 macros, and scala-parser-combinators works in Scala 3, but I've had a lot of trouble getting it to not be too greedy), so I used the state monad from cats to parse at the bottom of the file, which I think turned out fairly nice.

Agreed! I would say that parser combinators are the sweet spot and the right choice in most cases.

Scala has them as well, e.g.: https://com-lihaoyi.github.io/fastparse/

And the good thing is, you don't have to learn a completely new language/syntax, you can use the host language's syntax and you have full IDE support as well.

The only code differs for two parts is as follows - https://github.com/bhosale-ajay/adventofcode/blob/master/2023/ts/D07.test.ts - under 80 lines.

Easy day TypeScript, P1 - Brute Force, P2 - Formula

[LANGUAGE: TypeScript] Github - Under 40 lines, all parts running under 8ms.

[LANGUAGE: TypeScript] TypeScript - Running under 30ms (both parts)

F# This year I solved puzzles using TypeScript as well as F# - Day 18, 19, and 22 TBD

F# - After looking at some Python solution calculated the position of blizzard for nth time instead of maintaining the grid, which makes it easier with F#.
