I just use kino_aoc in my livebook.

Here’s the link: GitHub - ljgago/kino_aoc: A helper for Advent of Code (a smart cell) for Elixir Livebook

If found this one too that looks pretty nice:

Hello everyone,

Since this year is a bit special, I made a quick update so the library will not accept days >12 in 2025. Nothing else seems to require a change

Well a variable or two for path prefixes with sane defaults are not hard to setup.

But few people will use our tools, maybe nobody will ; there is no need for fully configurable stuff here, it’s not like a genral purpose application framework.

I do some of the days in Rust and I use a boilerplate, I don’t really care where the files are, I just do what the README tells me because I just want to solve the problems. The “app” does not need to be deployed somewhere, it just needs to compile and be called from the console.

Hello everyone,

I’ve added more helpers and documentation for my Advent Of Code library.

It’s still just a bunch of helpers to ease fetching and caching inputs, and generate boilerplate code and tests.

But I also updated the README file to be a comprehensive guide on how to use it and solve your first AoC puzzle. This is intended for Elixir beginners and/or AoC beginners.

For more seasoned alchemist elves, I still think the library adds value (I made it for myself after all). There is a TL;DR section in the README and a documentation for all the available commands.

Tell me if you find that useful, and if you have any idea to improve it!
