Crackerjack code style

Crackerjack Python

Crackerjack is a python coding style which uses a minimalist approach to produce elegant, easy to read, code.

crack·​er·​jack ˈkra-kər-ˌjak : a person or thing of marked excellence

Why Crackerjack?

Crackerjack works on the theory that with static typing and explicit class, function, variable, and other object names - the code should be straight forward to read. Documentation and tests should be able to write themselves using a generative ai. Crackerjack provides a set of guidelines and utilities to keep the codebase clean, elegant, standardized, and easily readable.

Crackerjack philosophy...

Virtual envs:

Let's face it virtual envs are a mess and a lot of time and resources are spent maintaining them. This pretty much says it all. Enough is enough.

Regression testing:

Again, here is what we believe become to be waste of time too. It takes more time to keep codebases compliant with previous versions of python than it does to just update your code to run the latest versions of python as they are released (within a liberal-ish timeline of course). Why are you running old versions of python anyway. There are various easy ways to keep your system python versions up-to-date and Docker containers for the latest versions are available immediately upon release. Most cloud providers will support the new versions in their virtual machines and containers shortly after release as well. If your dependencies break upon upgrade, file a bug report or fix it yourself. Simple enough.

...the Crackerjack solution:

Crackerjack uses PDM with PEP-582 (yes, PEP-582 has been rejected but PDM still supports it and Crackerjack will continue to use it!). No more virtualenvs. Update your system python versions as they are released and start migrating your code. Crackerjack, and Crackerjack'd packages, should support the latest python release's features within 2 month after the release and depend solely on that version. Again, if something breaks, file a bug report or, even better, fix it yourself (maybe even learn something new things in the process). Easy-peasy. You just saved yourself a zillion headaches and can sleep better at night now.

What does this package do?

This package:

• streamlines and standardizes code style across numerous packages

• removes pipenv, poetry, and hatch build, dependency management, and virtual environment management packages and replaces them with PDM using PEP-582 (work in progress)

• installs, or updates, a project's pre-commit tools as well as .gitignore & other config files to comply with evolving crackerjack standards

• runs the following pre-commit hooks (in order):

  • various core pre-commit hooks
  • black
  • ruff
  • creosote
  • flynt
  • pyanalyze
  • autotyping
  • refurb
  • pyright
  • ruff (again for sanity checking)
  • black (again for sanity checking)

• converts/creates documentation in Markdown (md) (work in progress)

• runs tests and generates pytest mock stubs if needed (work in progress)

• bumps the project version and publishes it to PyPI

• commits changes to git repositories

What are the rules?

(...more what you'd call "guidelines" than actual rules. -Captain Barbossa )

• code is statically typed

• all docstrings, README's, and other documentation is to be done in Markdown (md)

• format with black

• use aiopath.AsyncPath or pathlib.Path not os.path

• import typing as t

• do not capitalize all letters in configuration settings or constants (we diverge from PEP-8 here for not other reason than it looks ugly)

• functions that deal with path operations should get passed AsyncPaths or Paths - not strings

• if a class can be a dataclasses.dataclass, pydantic.BaseModel, or msgspec.Struct it should be

• force single line imports (will support isort Vertical Hanging Indent when ruff does)

• use PDM and PEP-582 for dependency management and package building/publishing

• use pdoc and mkdocs for producing documentation

• use pytest for testing

• be compliant with the latest python version within 2 months after release

Installation

From your projects root directory:

pdm add -d crackerjack

Usage

From your projects root directory:

python -m crackerjack

For a full list of options:

python -m crackerjack -h

When you ready to publish your project:

python -m crackerjack -p micro

The -p option not only publishes your project but will bump your project version for you. The options are 'micro', 'minor', and 'major'. Put the -c option at the end and commit the bumped version to your git repository at the same time.
