Is anyone else doing Advent Of Code in Nix? (github.com)

Recently got started with Nix and Home-Manager. I thought Advent Of Code would be a good way to get more comfortable with the Nix language.

I don't think I ever made it beyond Day 6 though, even in my most comfortable language (Python) so no idea where this will strand.

I am learning a lot about Nix though!

Have you used the Nix language outside of configuration? Let's share and discuss!

Your code looks awesome, I'm definitely going to steal some ideas from that, especially the lib.pipe really cleans up a lot of unnecessary bindings I did.

Doing a with import ./utils.nix is also a lot cleaner than nesting let statements.

You can also use the pipe operators; but they are still experimental features.

foo (bar (baz x)) = x |> baz |> bar |> foo = foo <| bar <| baz <| x

Nix regex sucks. Is there any package with a reasonable regex matchAll?

@F04118F if it’s for todays advent of code, I used split and it worked fine. See my live steam on YouTube or my GitHub .

Somehow I completely missed that split can do match groups.. Oopsie! I did it in Python today but I did make a completely functional (and way too complicated) algorithm.

Tap for spoilerThe way you handle the do and dont is much cleaner

@F04118F if i had known about match i probably would have gotten stuck also lol but luckily i used split once before and remembered it :) i made an issue in your github, hope thats ok, just to mention this in case you didnt see it on fedi!
