I’ll be doing Advent of Code 2021 primarily in haskell, and I threw together a project with some useful dependencies and convenience functions to make each day as swift and easy as I can.
Each day gets its own module, and they get imported into Main and put into a list, it’s pretty sweet.
There are some utility functions in Common for some nice things like running the parts of the day with output, fetching a day’s input from adventofcode.com directly and caching it, and a couple other things.
