Solutions to puzzles are organized into directories, one directory for each day — 01, 02, 03, …, 24, 25:
01:
eval-1 # solution for part 1, expects puzzle input on stdin
eval-2 # solution for part 2, expects puzzle input on stdin
example.txt # example input
input.txt # puzzle input (.gitignore-d)
To initialize these directories with the daily puzzles from adventofcode.com, store your session cookie value in session.txt and run:
./bin/init <day>
To invoke puzzle implementations from the project root, you can run:
./bin/eval <day> [part [--test|-t]]
For instance, ./bin/eval 5 and ./bin/eval 5 1 will invoke day 5 part 1.
Running ./eval 5 2 will invoke part 2.
Adding --test or -t after the part number, will use input from example.txt instead of input.txt.
