Submit Feedback

The best way to send feedback is to file an issue at

If you are proposing a feature:

  • Explain in detail how it would work.

  • Keep the scope as narrow as possible, to make it easier to implement.

Get Started!

Ready to contribute? Here’s how to set up sevivi for local development.

  1. Fork the sevivi repo on GitHub.

  2. Clone your fork locally:

    $ git clone
  3. Install all dependencies after installing poetry <>:

    $ cd sevivi/
    $ poetry install
    $ pre-commit install
  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

    Now you can make your changes locally.

  5. When you’re done making changes, check that your changes pass the tests and linters and that the docs can be built:

    $ py.test
    $ pre-commit run --all-files
    $ cd docs && make html
  1. Commit your changes and then push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
  2. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.

  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.

  3. The pull request should work for Python 3.7, 3.8 and 3.9, and for PyPi. This will be verified within the PR.


To run a subset of tests:

$ py.test tests.test_sevivi


A reminder for the maintainers on how to deploy. Make sure all your changes are committed, including an entry in HISTORY.rst and an update of the old version code in docs/ and pyproject.toml.

GitHub will then deploy to PyPI if tests pass.
