Advent of code

Welcome to the Advent of Code1 Kotlin project created by maiatoday using the Advent of Code Kotlin Template delivered by JetBrains.

This repository, has been heavily modified to my workflow. It is still used for solutions using Kotlin language, however it has some scripts and testing built in and a collections of libraries I built up over the time I have been doing these challenges.

Getting started for a fresh year

  1. Pick the latest starter branch or head of main and make a fresh branch for the year
  2. Setup the data download script
    • Add an env variable for $ADVENT_SESSION and $ADVENT_USER_AGENT
    • Test the script with this command aoc 1 It should download day 1 data
    • Change the year in the script to point to the correct url
  3. Update any Kotlin versions or gradle versions
  4. Run some tests to see if everything still works
  5. There are two options to work, either call the day code in the Main.kt or setup tests in the DayXX test file.

Using benchmarks

  • The build should be setup to use benchmarks, there is a test that shows how to run these.
  • Run the benchmarks with ./gradlew benchmark

Utils

  • There are some generalised utils in utils package. InputUtils for various input handling, GridUtils for some point and 3d point utilities.

Quickstart live code templates

The steps each day:

  1. Setup the day code with new file Dayxx and live template aoc
  2. Generate a test file and use taoc live template, populate imports
  3. Download test data and read question and get cracking to submit for ⭐️⭐️
