Tommy Graves (Dec 02 2022 at 05:40): Tommy Graves (Dec 02 2022 at 05:40):Here's my day 2 solution. I opted to hardcode the cases instead of building any logic today because I wanted to try out list pattern matching and I'm lazy.
Braydon Hall (Dec 02 2022 at 05:49):Nice! I did the same thing but did the math in my head and hard-coded the result :joy:
Luke Boswell (Dec 02 2022 at 07:27):Here is my Day 2 solution. I'm pretty happy with these parsers, felt really nice to work with. Thank you Roc devs!
Luke Boswell (Dec 02 2022 at 07:33):@Tommy Graves that's nice and simple, love it!
Andy Kluger (Dec 02 2022 at 09:25): Ghislain (Dec 02 2022 at 11:47):Even lazier than @Tommy Graves, very hardcoded solution :innocent:
Tommy Graves (Dec 02 2022 at 13:06):Brilliant! Of course splitting the individual line is unnecessary :face_palm:♂️
Shritesh Bhattarai (Dec 02 2022 at 13:14): JesterXL (Dec 02 2022 at 14:46):My Day 2; I had fun with tags, and they helped find a compiler error, but just hardcoded to numbers https://github.com/JesterXL/advent-of-code-2022/blob/main/day2/main.roc
Tommy Graves (Dec 02 2022 at 16:20):I made an alternative solution using tags to model the problem a bit: https://github.com/TAGraves/adventofcode2022/blob/main/day2_with_modeling.roc
Srinivas Rao-Mouw (Dec 02 2022 at 18:09):My day 2 solution. Excited to see everyone else's tag system, I feel like mine is pretty repetitive.
Srinivas Rao-Mouw (Dec 02 2022 at 20:44):stole your file loading logic @JesterXL , thank you
Ayaz Hafiz (Dec 02 2022 at 23:34):My day 2 - man im loving this. here is parser.roc
Ayaz Hafiz (Dec 02 2022 at 23:38):Does have me reaching for a List.findBy : List e -> (e -> [Found e, Unknown]) -> [Found e, Unknown]) function though. You can emulate it with walkTry of course but that requires one more parameter and the Continue/Break wrapper tags.
JesterXL (Dec 02 2022 at 23:55):@Srinivas Rao-Mouw I stole it from https://github.com/shritesh/advent/blob/main/2022/02.roc haha
Richard Feldman (Dec 03 2022 at 00:07):we should totally add a List.findBy to builtins! :100:
Logan Lowder (Dec 04 2022 at 03:40):Day2!
Think I'm starting to get the hang of it.
