Advent of Code, implemented in Rust

How to run with your AoC account

This suite can auto-download your personalized AoC input if you provide it with the session cookie from your logged in browser session.

1. Log in to Advent of Code in your browser.
2. Get the value of the cookie named "session" from the browser developer tools.
3. Store the value in your dotenv, e.g. in the file .env in the repo root path.
4. Set a valid User-Agent for HTTP requests in your dotenv, as requested by the AoC creator in this post.

AOC_SESSION=5361[...]1448
USER_AGENT="github.com/your_username/your_clone_of_this_repo by [email protected]"

If you do not want to use the auto-download feature, provide the downloaded AoC inputs manually with the following path scheme relative to the repository root: input/year20xx/dayxx.input.

Command-line usage

The code should be run with the cargo run --release command from the root path of the repo.

Examples:

Run the code for the latest day (no arguments):

cargo run --release

Run the code for a specific day of the most recent year:

cargo run --release 11

Run the code for a specific year / day:

cargo run --release 2016 11

Run all implemented days for a single year:

cargo run --release 2016 all

Code structure

A solution for each day is implemented in a single Rust source file: yearxxxx/src/dayxx.rs.

Re-used code has been moved to the subcrate util.

Tests

AoC example input is implemented as unit tests in the respective file.
