Contributing

When contributing to this repository, please first discuss the change you wish to make via issue, email, or any other method with the owners of this repository before making a change.

Code Style

Please adhere to PEP8 style guidelines unless called out in this document.

1. Add 3 lines of whitespace between classes and free functions.
2. Prefer 2 lines of whitespace between methods within classes.
3. Prefer all methods in classes should have an explicit return statement.
4. All pytest tests shoud return 0 if the test is successful.
5. Conform to Google-style docstrings except for where it might break Sphinx formatting.
6. Lines should not exceed 120 columns except in cases where it reduces the readability of the code.

Auto-formatting

We can also use the YAPF tool to perform auto-formatting. The .style.yapf file provides a formatting scheme that is also good. Using this breaks (2) above, it will only add 1 line between method definitions so this should be adjusted manually.

Versioning

This project uses Semantic Versioning.

Merge Request Process

1. Ensure any unapproved install or build dependencies are removed before submitting a merge request.
2. Update the CHANGELOG.md file with details of the changes you are making.
3. Update relevant documentation in the doc/ folder and any appropriate docstrings.
4. Update unit tests to fully test your additions. We aim for 100% coverage on this project.
5. Ensure unit tests and documentation build cleanly by running exec-tests.sh, exec-makedoc.sh and the example applications in the repository.
6. Run the exec-reformat.py script in the repository's root directory to update all formatting using the YAPF tool. This is optional but STRONGLY encouraged, we reserve the right to reject a merge request if this hasn't been run.
