Advent of Code Helper Library

A library that lets you focus on problem-solving rather than boilerplate when doing Advent of Code.

This library utilises Rust's testing framework to run each part of each day with either real live inputs from adventofcode.com or your own test inputs.

It also contains a few utility functions to speed up common input transformations.

Installation

Place the following in your Cargo.toml dependencies section:

[dependencies]
aoc-lib = "1.0.0"

or you can do a cargo add aoc-lib.

Usage

Cookie

The auto-download functionality needs a cookie to authenticate with AOC.

Get the adventofcode.com cookie value from your browser and place it in a ~/.aoc.cookie file (name: .aoc.cookie, in your home folder).

There's many browser extensions that let you view your cookies.

Your Repository

Follow the below example as closely as possible:

src
├── lib.rs
└── year2022
    ├── day01.rs
    └── mod.rs

The year folders must follow the regex ^year\d\d\d\d$ and the days must follow the regex ^day\d\d\.rs$.

Hint: To avoid unused warnings, your mod.rs file should use pub: pub mod dayXX and similarly for your lib.rs: pub mod year2022.

Here's a template dayXX.rs file:

pub fn part1(_input: String) -> usize {
    0
}

pub fn part2(_input: String) -> usize {
    0
}

#[cfg(test)]
mod tests {
    use super::*;
    use aoc_lib::*;

    #[test]
    fn test_part1() {
        run_test!(part1);
    }

    #[test]
    fn run_part1() {
        run_real!(part1);
    }

    #[test]
    fn test_part2() {
        run_test!(part2);
    }

    #[test]
    fn run_part2() {
        run_real!(part2);
    }
}

After all the above is set up, just run the tests!

Before you commit anything, don't forget to .gitignore the /input folder.
