Advent of Code Solutions

Here be answers/solutions to Advent of Code challenges for various years.

Answers are divided into individual subdirectories for each year and day.

cmd/aoc contains a small CLI tool for automatically generating subdirectory structure, pre-populating each day with files to be completed.

cmd/aoc-announce, and the associated Docker image, ghcr.io/arylatt/advent-of-code/aoc-announce:latest, is a tool for watching a private leaderboard and sending notifications to a Discord channel via a webhook when players complete puzzles.

elves is my helper package. It contains functionality to:

• Enable easier testing of the samples provided as part of the challenge descriptions
• Automatically pull the full inputs when running the test case (uses session cookie placed in AOC_SESSION_COOKIE env var)
• Automatically submit answer from test case to AoC (uses AOC_SESSION_COOKIE and is enabled by setting AOC_SUBMIT_ANSWERS to any non-empty value)
