Welcome to mightypy contributor’s guide.

Please notice, all users and contributors are expected to be open, considerate, reasonable, and respectful. When in doubt, Python Software Foundation’s Code of Conduct is a good reference in terms of behavior guidelines.

Issue Reports#

If you experience bugs or general issues with mightypy, please have a look on the issue tracker. If you don’t see anything useful there, please feel free to fire an issue report.


Please don’t forget to include the closed issues in your search. Sometimes a solution was already reported, and the problem is considered solved.

New issue reports should include information about your programming environment (e.g., operating system, Python version) and steps to reproduce the problem. Please try also to simplify the reproduction steps to a very minimal example that still illustrates the problem you are facing. By removing other factors, you help us to identify the root cause of the issue.

Documentation Improvements#

You can help improve mightypy docs by making them more readable and coherent, or by adding missing information and correcting mistakes.

mightypy documentation uses Sphinx as its main documentation compiler. This means that the docs are kept in the same repository as the project code, and that any documentation update is done in the same way was a code contribution.

When working on documentation changes in your local machine, you can compile them using tox:

tox -e docs

and use Python’s built-in web server for a preview in your web browser (http://localhost:8000):

python3 -m http.server --directory 'docs/_build/html'

Code Contributions#

Submit an issue#

Before you work on any non-trivial code contribution it’s best to first create a report in the issue tracker to start a discussion on the subject. This often provides additional considerations and avoids unnecessary work.

Create an environment#

Before you start coding, we recommend creating an isolated virtual environment to avoid any problems with your installed Python packages.

python -m venv .venv source .venv/bin/activate

Clone the repository#

  1. Create an user account on GitHub if you do not already have one.

  2. Fork the project repository: click on the Fork button near the top of the page. This creates a copy of the code under your account on GitHub.

  3. Clone this copy to your local disk:

    git clone
    cd mightypy
  4. You should run:

    pip install -U pip
    pip install -U tox -e .

    to be able to import the package under development in the Python REPL.

Implement your changes#

  1. Create a branch to hold your changes:

    git checkout -b my-feature

    and start making changes. Never work on the main branch!

  2. Start your work on this branch. Don’t forget to add docstrings to new functions, modules and classes, especially if they are part of public APIs.

  3. Add yourself to the list of contributors in AUTHORS.rst.

  4. When you’re done editing, do:

    .. todo:: if you are not using pre-commit, please remove the following item:

    Please make sure to see the validation messages from pre-commit and fix any eventual issues. This should automatically use flake8/black to check/fix the code style in a way that is compatible with the project.


    Don’t forget to add unit tests and documentation in case your contribution adds an additional feature and is not just a bugfix.

    Moreover, writing a descriptive commit message is highly recommended. In case of doubt, you can check the commit history with:

    git log --graph --decorate --pretty=oneline --abbrev-commit --all

    to look for recurring communication patterns.

  5. Please check that your changes don’t break any unit tests with:


    (after having installed tox with pip install tox or pipx).

    You can also use tox to run several other pre-configured tasks in the repository. Try tox -av to see a list of the available checks.
