Advent of code solutions in PHP

Events added

• 2020
• 2021 (default)

Requirements

• Advent of Code account
• Docker & Docker Compose

Installation

Clone the repository.

Put your session token under: .env.local file to be able to download inputs

docker-compose up -d then docker-compose exec app composer install

Usage

Execute those inside the docker container:

Generate class for solution for given event & day

./app generate - Generate for current year, current day

./app generate 15 - Generate for current year, day 15

./app generate 21 --event 2020 - Generate for event 2020, day 21

./app generate --event 2016 - Generate for event 2016, current day (if between 1 and 25)

Test and execute solutions

If year is not given (-y xxxx or --event xxxx), then it takes current year if we're in December, otherwise it takes the last available event

./app solve -d 1 - to execute day 1 with AoC user input (downloaded automatically)

./app solve -d 1 -y 2019 - to execute day 1 with user input (downloaded automatically) for event 2019

./app solve -d 1 --test - to execute solution for day 1 with tests inputs (defined in the solution class)

./app solve -t 2020 -d 1 --validate - validate already solved day 1 year 2020 in AoC, downloading the answers and checking the solution against them

This repo does follow the automation guidelines on the /r/adventofcode community wiki https://www.reddit.com/r/adventofcode/wiki/faqs/automation. Specifically:

• Once inputs are downloaded, they are cached locally
• If you suspect your input is corrupted, you can manually request a fresh copy by deleting the input file: /inputs/{year}/{day}
• The User-Agent header in requests to AoC is set to me since I maintain this repo :)
