If you're reading this you probably either want to see my solutions -- they're arranged by year and then day at src/aoc -- or you want to run them. Maybe you're me from the future. Entry points for running solutions and tests are in the user namespace, you probably want run-tests, run, or rrr (do all of refresh, run tests, and then run).

run will download input (exactly once ever for each puzzle) and submit solutions (or check them against a local cache). When it does make requests it looks for a .session file.

Solutions are functions of no arguments called part-1 or part-2 in the relevant namespace. run will also run functions called scrap for the purpose of checking intermediate results without submitting anything.

Arguments to run (and run-tests and rrr) are integers: year, day, part; all optional.

• (run) runs everything
• (run 2021) runs every day in 2021
• (run 2015 19) runs 2015 day 19
• (run 2017 1 2) runs 2017 day 1 part 2
• (run 24) runs day 24 in whatever user/default-year currently is

(log) spits the output of (run) to results.log.
