Introduction

Advent of Code (AOC) is crated by Eric Wastl and is an annual advent calendar of small programming puzzles. They can be solved in any language (you don't really need code at all to solve some of them) and its intended for people of all skill levels. There are a total of 25 exercises per year, one per day starting on December 1st and ending on December 25th (Christmas).

You can find all of the advent of code exercises on the official website here:

Overview

I'm using AOC as an opportunity to sharpen my rust skills and get more familiar with the language and toolchain.

This AOC crate serves as a dummy top-level create that links to each of the other years.

The repository is structured as follows:

• Each year is a cargo workspace
• Each day is a cargo crate

Cheers & happy coding!

How to use

There are two ways that you can run the code in this repository:

• Run it using Replit
• Run it locally

Running in replit

You can now run all of the examples in this repository without installing any rust toolchains or dependencies directly in the browser here:

https://replit.com/@hkennyv/aoc#README.md

Simply go to the link above, skip the running locally section below and go straight to the running the code section.

Running locally

In order to run locally, you'll have to install the rust toolchain using rustup. See below.

Prerequisites

• install rust using rustup (this should install the cargo toolchain as well). using the nightly build is recommended

Running the code

Any day of the AOC can be run by going into that day's directory and running:

$ cd 2020/day10
$ cargo run --release

NOTE: everyone's input for the advent of code is different. I've committed the input for my account in this repository and the answers for my input in the documentation, however, feel free to run the solutions using your own input. Each crate reads from an "input.txt" file in their respective directories.

Documentation

Bonus: I've added the description of each day's challenge to the crate description so you can view all of the challenges and all of the functions and their docstrings that I used.

To build the documentation for each workspace, simply run the following command in the year's workspace:

cargo doc --workspace --open

The documentation should automatically open up in your browser. Each of the AOC days should appear in the left-hand sidebar as its own crate that you can choose to view.

README

NOTE: this readme is generated using cargo-readme.

To edit the README, please edit the src/main.rs file and regenerate the README using the following command:

cargo readme > README.md

Tests

Many crates also have some runnable tests that you can run using:

cargo test

Alternatively, run tests for the entire workspace using:

cargo test --all
