Contributing

Everyone is invited to contribute to this project. Feel free to create a pull request . If you find errors, omissions, inconsistencies, or other things that need improvement, please create an issue.

Development Installation

Instead of pip-installing the latest release from PyPI, you should get the newest development version from Github:

git clone https://github.com/audeering/audb/
cd audb
# Create virtual environment for this project
# e.g.
# virtualenv --python="python3"  $HOME/.envs/audb
# source $HOME/.envs/audb/bin/activate
pip install -r requirements.txt

This way, your installation always stays up-to-date, even if you pull new changes from the Github repository.

Coding Convention

We follow the PEP8 convention for Python code and use ruff as a linter and code formatter. In addition, we check for common spelling errors with codespell. Both tools and possible exceptions are defined in pyproject.toml.

The checks are executed in the CI using pre-commit. You can enable those checks locally by executing:

pip install pre-commit  # consider system wide installation
pre-commit install
pre-commit run --all-files

Afterwards ruff and codespell are executed every time you create a commit.

You can also install ruff and codespell and call it directly:

pip install ruff codespell  # consider system wide installation
ruff check --fix .  # lint all Python files, and fix any fixable errors
ruff format .  # format code of all Python files
codespell

It can be restricted to specific folders:

ruff check audfoo/ tests/
codespell audfoo/ tests/

Building the Documentation

If you make changes to the documentation, you can re-create the HTML pages using Sphinx. You can install it and a few other necessary packages with:

pip install -r docs/requirements.txt

To create the HTML pages, use:

python -m sphinx docs/ build/sphinx/html -b html

The generated files will be available in the directory build/sphinx/html/.

It is also possible to automatically check if all links are still valid:

python -m sphinx docs/ build/sphinx/html -b linkcheck

Running the Tests

You’ll need pytest for that. It can be installed with:

pip install -r tests/requirements.txt

To execute the tests, simply run:

python -m pytest

Creating a New Release

New releases are made using the following steps:

  1. Update CHANGELOG.rst

  2. Commit those changes as “Release X.Y.Z”

  3. Create an (annotated) tag with git tag -a X.Y.Z

  4. Push the commit and the tag to Github
