Advent of Code Elixir

Getting started

Setting ENV (Optional)

cp .env.example .env

Copy and insert your cookie (required only to download new inputs or running live submission)

Downloading your inputs

mix download 2020 1

This will download and place your inputs inside the folder required for the computation to run

Generating the day module and related tests

mix gen.aoc 2020 5

This will set up your day, day test and download your input all in one go

Runnning computations

iex(1)> Aoc.Y2020.D1.run
Part 1: 926464
Part 2: 65656536
:ok
iex(2)> Aoc.Y2020.D1.run 1
926464
iex(3)> Aoc.Y2020.D1.run 2
65656536

Equivalent would be

iex(1)> Aoc.Runner.run 2020,1,1
926464
iex(2)> Aoc.Runner.run 2020,1,2
65656536

If you're too lazy to type I've added .iex.exs script to import Aoc.Runner which means you can access Aoc.Runner.run without namespacing it

iex(1)> run 2020,1,1
926464
iex(2)> run 2020,1,2
65656536
iex(3)> run 2020,1
Part 1: 926464
Part 2: 65656536
:ok

The repo contains year and day separated modules that has macros to run the solution dates in Aoc.Runner. The parts can be executed directly with Aoc.Y2020.D1.part1 or Aoc.Y2020.D1.part2 though the macros provide an easy way to quickly run given there's already an input.
