2021-advent-of-code

Each day, advent of code presents a challenge for those of brave heart to complete. This repo contains my answers to the 2021 version of advent of code, not all challenges have been completed. I complete AoC to get familiar with a technology, its build tools and testing tools, it's kind of a mini-production type workflow I follow.

In this year I chose to use the following tools:

• Python v3.11.5. Language for this years AOC solutions.
• black v23.9.1. Prettifier for python code.
• ruff v0.1.0. Linter for python code.
• isort v5.12.0. Sorts imports in python code.
• pytest v7.4.2. Testing framework for python code.
• pre-commit v3.5.0. Used for pre commit hooks.

All development was completed using PyCharm which is an awesome IDE.

Setup

With Python, I like to work with virtual envs, this keeps the development environments for each project separate.

First step is to install the version of python to use. I use pyenv to manage my python versions, so I install the version I want to use with the following command:

pyenv install 3.11.5

Next I create a virtual environment for the project:

pyenv virtualenv 3.11.5 2021-advent-of-code

Then I activate the virtual environment:

pyenv activate 2021-advent-of-code

Finally, I install the dependencies:

pip install -r requirements-dev.txt

My environment is now setup and ready to go.

Testing

$ make test

Committing

The pre-commit hook should kick-in, when it does it will lint and prettify the code.

$ git add --all
$ git commit -a
