Python Radioplayer Dataclasses

Classes for generating radioplayer compatible data. Generated using xsdata.

Installation

pip install radioplayer-dataclasses

Usage

The radioplayer.dataclasses module may be used to build radioplayer compatible structures. Serializing is done using the xsdata library.

>>> from radioplayer.dataclasses import *
>>> epg = Epg(lang="en")
>>> epg
Epg(programme_groups=[], schedule=[], alternate_source=[], lang='en', system=<SystemType.DAB: 'DAB'>)

>>> from xsdata.formats.dataclass.serializers import XmlSerializer
>>> from xsdata.formats.dataclass.serializers.config import SerializerConfig
>>>
>>> config = SerializerConfig(
...     pretty_print=True,
...     xml_declaration=False,
... )
>>> serializer = XmlSerializer(config=config)
>>> xml = serializer.render(epg, ns_map={None: Epg.Meta.namespace})
>>> print(xml.strip())
<epg xmlns="http://www.radioplayer.co.uk/schemas/11/epgSchedule" xml:lang="en" system="DAB"/>

Additional examples are available in the tests/ directory.

Development

Some touchups where made to the files to make them validate where necessary.

Generating dataclasses

poetry run xsdata -c .xsdata.xml schemas/

Running tests

poetry run pytest

Release Management

The CI/CD setup uses semantic commit messages following the conventional commits standard. There is a GitHub Action in .github/workflows/semantic-release.yaml that uses go-semantic-commit to create new releases.

The commit message should be structured as follows:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

The commit contains the following structural elements, to communicate intent to the consumers of your library:

1. fix: a commit of the type fix patches gets released with a PATCH version bump
2. feat: a commit of the type feat gets released as a MINOR version bump
3. BREAKING CHANGE: a commit that has a footer BREAKING CHANGE: gets released as a MAJOR version bump
4. types other than fix: and feat: are allowed and don't trigger a release

If a commit does not contain a conventional commit style message you can fix it during the squash and merge operation on the PR.

Once a commit has landed on the main branch a release will be created and automatically published to pypi using the GitHub Action in .github/workflows/release.yaml which uses poetry to publish the package to pypi.
