How to report a bug

Report bugs on the Issue Tracker.

When filing an issue, make sure to answer these questions:

• Which operating system and Python version are you using?
• Which version of this project are you using?
• What did you do?
• What did you expect to see?
• What did you see instead?

The best way to get your bug fixed is to provide a test case, and/or steps to reproduce the issue.

How to set up your development environment

You need Python and the following tools:

• Poetry
• Nox
• nox-poetry
• Quarto
• Make]

Install the package with development requirements:

$ poetry install

You can now run an interactive Python session, or the command-line interface:

$ poetry run python
$ poetry run skimpy

To build the documentation, you will also need Quarto and Make. You can preview the docs using poetry run quarto preview --execute. You can build them with make, which runs

poetry run jupyter nbconvert --to markdown --execute index.ipynb && mv index.md README.md

to build the readme and

poetry run quarto render --execute

to build the documentation website behind the scenes.

How to test the project

Run the full test suite:

$ nox

List the available Nox sessions:

$ nox --list-sessions

You can also run a specific Nox session. For example, invoke the unit test suite like this:

$ nox --session=tests

Unit tests are located in the tests directory, and are written using the pytest testing framework.

You may need to use, for example, poetry run nox to ensure that the tests are run in the right environment.

For the pre-commit checks, use

$ poetry run pre-commit run --all-files

How to submit changes

Open a pull request to submit changes to this project.

Your pull request needs to meet the following guidelines for acceptance:

• The Nox test suite must pass without errors and warnings.
• Include unit tests. This project aims to maintain 100% code coverage.
• If your changes add functionality, update the documentation accordingly.

Feel free to submit early, though—we can always iterate on this.

To run linting and code formatting checks before commiting your change, you can install pre-commit as a Git hook by running the following command:

$ nox --session=pre-commit -- install

It is recommended to open an issue before starting work on anything. This will allow a chance to talk it over with the owners and validate your approach.
