Advent of Code solutions

This project holds my Python solutions + utilities for Advent of Code puzzles over the years.

Run it

To run solutions and utilities, first you must install dependencies. I highly recommend using a virtual environment for this. I've been using pipenv for that lately.

pipenv install
# start a new shell within the virtualenv. The shell (and virtualenv) can be exited normally, with `exit` or Ctrl-D.
pipenv shell

Once that's done, you can run solutions like so:

python -m adventofcode run [-y <year>] <day>

If the input for the solution you're trying to run hasn't already been saved in the inputs directory, the program will try to download it from the Advent of Code site first. If this is your first time downloading an input, you'll be asked to provide your unique session id. It's held in a cookie named session saved by the site--you can view it using your browser's dev tools or a number of cookie-viewing browser extensions.

---

To set up solution and test directories for a new year of puzzles, run

python -m adventofcode init [-y <year>]

The year param is optional in both of the adventofcode commands, and if not specified the latest year listed in the solutions directory (or latest year + 1 for init) is used.
Note: this command's output will be nicer if you have the tree shell command installed!

Test it

Assuming you've installed dependencies as described above, you can run tests with the following:

# run all tests
PYTHONPATH=$(pwd) py.test
# run a specific test
PYTHONPATH=$(pwd) py.test path/to/test.py

Copy it

If you like the setup I've got here, feel free to use it yourself. Or let me know if it's garbage! This is my first time making a proper Python project from scratch, so I'm sure it's not perfect. ¯\_(ツ)_/¯
