Advent of code container project

This project contains code used to solve Advent of Code puzzles.

Puzzles are solved using Scala 3.

What you need

In order to run this project, you need to use sbt.

You can find more detailed instructions on how to setup your environment here.

Multi Year project

It may be a little bit of overthinking, but the sbt project is structured to contain solutions for puzzle for multiple years. 😅

Once the sbt prompt shows up, you need to switch to the current year in order to run its puzzles:

sbt:AdventOfCode> l
[info] In file:<project folder>
[info]   * AdventOfCode
[info]     Year_2021
sbt:AdventOfCode> cd Year_2021
[info] set current project to 2021 (in build file:…)
sbt:Year_2021> 

Solving puzzles

Puzzle inputs

In order to run puzzles, you first need to replace the puzzle inputs (the ones included in the project are @gcsolaroli's ones); these files are located in the <YEAR>/src/main/resources folder.

It should be enough to just save the page with your input into the matching file (named Day__.input.txt) as plain text.

Run solutions

Once started sbt, in order to run a solution, you just need to use the runMain command. eg:

runMain it.imolab.adventOfCode._2021.Day01.answer_1

sbt provided an autocompletion feature, so you don't have to type the fully qualified name of the method you want to run, but you can use tab key to let sbt helps you in selecting the right method.
