antsibull-core is covered by the Ansible Code of Conduct.

Versioning and compatibility

From version 1.0.0 on, antsibull-core sticks to semantic versioning and aims at providing no backwards compatibility breaking changes during a major release cycle. We might make exceptions from this in case of security fixes for vulnerabilities that are severe enough.

The current development version is 3.x.y. 3.x.y is developed on the main branch. The current supported major version is 2.x.y. Development for 2.x.y occurs on the stable-2 branch. 1.x.y is End of Life and was developed on the stable-1 branch. It is no longer updated. 2.x.y mainly differs from 1.x.y by dropping support for Python 3.6, 3.7, and 3.8. It deprecates several compatibility functions for older Python versions that are no longer needed; see the changelog for details.

Development

Install and run nox to run all tests. That's it for simple contributions! nox will create virtual environments in .nox inside the checked out project and install the requirements needed to run the tests there.

antsibull-core depends on the sister antsibull-fileutils project. By default, nox will install a development version of this project from Github. If you're hacking on antsibull-fileutils alongside antsibull-core, nox will automatically install this project from ../antsibull-fileutils when running tests if this path exists. You can change this behavior through the OTHER_ANTSIBULL_MODE env var:

• OTHER_ANTSIBULL_MODE=auto — the default behavior described above
• OTHER_ANTSIBULL_MODE=local — install the project from ../antsibull-fileutils. Fail if this path doesn't exist.
• OTHER_ANTSIBULL_MODE=git — install the project from the Github main branch
• OTHER_ANTSIBULL_MODE=pypi — install the latest version from PyPI

To run specific tests:

1. nox -e test to only run unit tests;
2. nox -e coverage to display combined coverage results after running nox -e test;
3. nox -e lint to run all linters and formatters at once;
4. nox -e formatters to run isort and black;
5. nox -e codeqa to run flake8, pylint, reuse lint, and antsibull-changelog lint;
6. nox -e typing to run mypy and pyre

Creating a new release:

1. Run nox -e bump -- <version> <release_summary_message>. This:
   • Bumps the package version in src/antsibull_core/__init__.py.
   • Creates changelogs/fragments/<version>.yml with a release_summary section.
   • Runs antsibull-changelog release and adds the changed files to git.
   • Commits with message Release <version>. and runs git tag -a -m 'antsibull-core <version>' <version>.
   • Runs hatch build.
2. Run git push to the appropriate remotes.
3. Once CI passes on GitHub, run nox -e publish. This:
   • Runs hatch publish;
   • Bumps the version to <version>.post0;
   • Adds the changed file to git and run git commit -m 'Post-release version bump.';
4. Run git push --follow-tags to the appropriate remotes and create a GitHub release.
