Advent of Code CLI Bundle

This bundle helps to create puzzle implementations for Advent of Code.

Key features:

• Tests your code against the demo input + expected answer
• Automatically downloads your full puzzle input
• Automatically submit your answer to Advent of Code

Installation

Prerequisites

This bundle is based on Symfony and relies on Symfony's core components Dependency Injection and Console Commands.

Installation

Install using composer:

And register your bundle in config/bundles.php if not done already by Symfony Flex:

Features and usage

Register puzzle solution implementation

• Create a class and method containing your puzzle solution implementation.
• Your method should accept one single argument of the type PuzzleInput and should return an integer or string (int|string).
• Register your method by adding the #[Puzzle] attribute.
• Add one or more #[TestWithDemoInput] attributes to test your implementation against the demo input and verify it gives the expected answer.
• Make sure your puzzle class is registered as (Symfony) service.

See the example puzzle implementation for more guidance.

Authenticate to Advent of Code

This bundle can retrieve your full puzzle input from Advent of Code and automatically submit your answer. Run bin/console aoc:auth and follow the instructions.

Run your puzzle solution

Use the bin/console aoc:run command to run your puzzle. This will first test your code against the demo input provided with the #[TestWithDemoInput] attribute(s). When these tests were successful it will run your code with the full puzzle input and submit your answer to Advent of Code.

Puzzle selection

• bin/console aoc:run will run the last puzzle implementation in your project (highest year + day + part).
• bin/console aoc:run year [day] [part] will run all puzzle implementations in the given year + optional day + optional part.
• bin/console aoc:run --all will run all puzzles implementations

Automatically submitting your solution

The automatic submission of your solution can be managed with

• Using the --submit or --no-submit flags on bin/console aoc:run
• Setting the ADVENT_OF_CODE_AUTO_SUBMIT environment value (e.g. in .env.local)

List all your puzzle solutions

Run bin/console aoc:list to list all your puzzle implementations within your project.

IDE integration

To run your puzzle implementation directly from your IDE, the binary vendor/bin/puzzle-php-bridge can be used. Read the IDE configuration instructions.
