Advent of Code 2021

Usage

Clone the repo and cd into the directory.

Using the runner

Load the runner into an irb instance

irb -r ./runner.rb

Using Pry

Install the pry gem, then load the runner into the pry instance.

gem install pry
pry -r ./runner.rb

From irb you can now call any of the day/part combinations with their test inputs

$irb> runner = Runner.new(day: 1, part: 1, test: true)
$irb> runner.perform
 ==> 7

If you make changes to the solution.rb file that you're working on, you can reload it without exiting the IRB instance.

$irb> runner.reload
  ==> true
