Advent of Code

Advent of Code is a yearly programming challenge that encourages people to solve problems using programming. This repository holds any attempts I make at completing the challenge!

Years

2020, 2021, 2022, 2023, 2024: Rust

I decided to do the 2020, 2021, 2022, 2023, and 2024 challenge using Rust. I don't use Rust professionally, so I want to flex my problem solving skills with it using Advent of Code.

Running the Project

• Install the Rust tooling
• Navigate to rust-202#/ for whatever year you want to run
• cargo run will run a CLI program that outputs info for each of the challenges
• cargo test will run all the unit tests

How to Use the aoc-utils Crate

• Install the utils crate to your system by running cargo install --path aoc-utils from the root of the repository.
• Get the session token by inspecting an authenticated request to the Advent of Code website. There's not currently an easier way that I know, unfortunately.
• Place that session token in a .env file at the root of the repository with the key AOC_SESSION_TOKEN.
• Use the aoc-utils command as you're developing your solutions! See what's available by running aoc-utils --help.

Needed Updates

aoc-utils

• More helper functions for common input parsing needs
• Run a single day instead of all of them
• Instructions on how to use the CLI tooling
• Submission of answers (and rate limiting so I don't accidentally spam the server)
• Publish helper crates to crates.io
• More CLI options (like setting the input storage directory)
• Festive ASCII art

Problem Solving Code

• Remove deprecated read_input function in 2021's code
• Set up a workspace so I can have all years depend on workspace dependencies, which makes me feel better about pulling in a variety of helpful crates
