Advent of Code

My solutions to Advent of Code.

Structure

Each day of each year is implemented in a package of the form :aoc<year>.<day> which has a function named day<day> that returns the solutions of that day's part 1 and part 2 as multiple values. For example: day 11 from year 2021 is implemented in the package :aoc2021.11 and has a function day11.

Testing

To run all tests use (asdf:test-system :advent-of-code):

CL-USER> (asdf:test-system :advent-of-code)

In order to run a test for a specific day call parachute:test with that day's package as argument, e.g. for day 14 of the 2021 event or day 10 of the 2022 event:

AOC2021.14> (parachute:test *package*)
...
AOC2021.14> (parachute:test (find-package :aoc2022.10))
...

Pitfalls

This repository doesn't include the problems' inputs or examples, see this. You can't just clone it and run the tests or the code right away, you'll need to provide the inputs yourself which will likely be different from my own so the tests as they are defined probably don't make any sense for you.
