Advent of Code 2021

Robert Haines

My attempt at doing Advent of Code 2021 in Ruby, with tests and all the trimmings.

Usage

After cloning, and changing into the aoc-2021 directory, run:

$ gem install bundler
$ bundle install
$ rake

This will set everything up and run all the tests.

To run the solution for a particular day:

$ ./aoc-2021 <day>

Or via rake:

$ rake run <day>

You can run multiple days like this:

$ rake run <day_1> <day_2> ... <day_n>
