🎄 Advent of Code

Solutions for Advent of Code puzzles in languages I enjoy.

Environment variables

Update the AOC_LANGUAGE and AOC_YEAR environment variables in bin/env to match your preferences. They determine which puzzles to download and which solution files to run and submit.

Commands

$ bin/new <day><part> # start a new puzzle in the active year
$ bin/run <day><part> # run a puzzle solution in the active year
$ bin/submit <day><part> # submit a puzzle answer in the active year

For example:

$ bin/new 1a # download the 2015, day 1, part 1 puzzle and its input and generate solution files
$ bin/run 25b # output my 2023, day 25, part 2 answer
$ bin/submit 25b # submit my 2023, day 25, part 2 answer

Find the cookie named "session" and copy its value into a .aoc-session-cookie file at the root of this project (it won't be tracked).
