Advent of Code

This is my repository for the Advent of Code (https://adventofcode.com/), starting from 2021.

File Structure

Inside each year folder, such as 2021/, there are folders for each day's puzzles (dayN). These contain 2 files each: dayN.py (my solutions w/ Python) and dayN.txt (input data).

Day Initialization

A few minutes before 12:00 AM EST, run initialize.py. The script creates the folder and Python file (from template.py) for the day. Then, it checks in 0.5s intervals for midnight, upon which it downloads the input file for the day to dayN.txt inside the proper folder.

The automatic input file downloading is made possible by the session cookie in AoC. The cookie value can be found in the Application tab of Inspect Element, Storage > Cookies > session. Create a .env file in the root project folder with content

session=cookie_value_here

Dependencies

The dependencies for this repository are saved in a requirements.txt. Be sure to create a venv (I used Python 3.10.0), activate it, and run

pip install -r requirements.txt
