AOC Utilities

This is a little python utility package to help with my Advent of Code challenges.

Setup

To use, first install:

git clone [email protected]:loganmeetsworld/aoc_utils.git
cd aoc_utils
pip3 install .

Then you will also need a session cookie setup. You can find your session cookie by logging into adventofcode.com and inspecting your session with developer tools. You'll need to set this in the environment. I do this with a script that contains the following:

export SESSION_COOKIE="cookie"

Once you have the module installed and the session cookie set you can use by importing like:

from aoc_utils import aoc_utils

Current it is just one module for the package. One you have it there are several functions available. The package assumes you are in a current directory of the problem you are trying to solve. The run method allows you to enter the year and day if you want to specify. For me, I have all my problems formatted advent_of_code/2019/1 which allows me to guess the year and day.

We can fetch our input or our problem within a folder like so:

year = 2019
day = 1
problem_input = aoc_utils.fetch_and_save('input|problem', year=year, day=day)

This will fetch the input.txt and problem.txt if they do not exist, otherwise will fetch the problem_input from a saved input.txt file.

We can submit answers to AOC via an answer() function that takes the input and part we are working on.

year = 2019
day = 1
level = 1

def answer(level, input):
    print('solve puzzle')

aoc_utils.submit(level, answer, year=year, day=day)

We can also test with test cases that look like this:

test_cases = [
  {'level': 1, 'input': '12', 'output': '100'}
]

and test like this:

test_cases = [
  {'level': 1, 'input': '12', 'output': '100'}
]
def answer(level, input):
    print('solve puzzle')

# Test returns a bool
passed_all = aoc_utils.test(answer, test_cases)

and then finally, when you put it all together, you simply use run() which will pull input, test based on a list of cases, and then attempt to submit answers.

year = 2019
day = 1
test_cases = [
  {'level': 1, 'input': '12', 'output': '100'}
]
def answer(level, input):
    print('solve puzzle')

aoc_utils.run(answer, test_cases=test_cases, year=year, day=day)

We keep state of what questions we've gotten right in a a stars.txt file created for correct answers. Test cases are optional. If there are no tests, it will move to submit.
