Advent of Code 2019

First time doing this event! I'm excited!

This repository is my attempt at the 2019 edition of AdventOfCode, using the Crystal programming language.

This project is also my first time using the Nix package manager 🎉.

Build & run using Nix

Build all puzzles using nix-build or specific day using nix-build -A day2.

Then the built puzzles are symlinked by nix-build in the current directory.

Run using crystal directly

Each day puzzle can be run using: crystal run ./day2/day2.cr
