Advent of Code

Solutions for Advent of Code puzzles, written in Rust.

Getting Started

1. Clone the repository.

git clone https://github.com/jontmy/aoc-rust
cd aoc-rust

2. Get your SESSION_TOKEN from the session cookie on adventofcode.com and save it in .env.

vim .env  # add SESSION_TOKEN=...

3. Run the solver for a specific puzzle. The solver will automatically download the puzzle input and cache it.

cargo run --release -- -d <day> -y <year>

Tip

If Advent of Code is currently ongoing, the -d and -y flags can be omitted. The current system date will be used instead.

Other tips

• The -i flag lets you specify a custom file extension for the file which the input will be read from. Useful for example inputs.
• For example, -d 1 -y 2024 -i ex1 will read from input/2024/01.ex1 (note the leading zero).
• Setting the -r flag will re-download the input.
