Statick-planning

Changed

- Run deployment actions on ubuntu-latest.
- Make setup.py and tox.ini consistent with supported versions.
- Update versions of actions to use only tags.
- Unpin sphinx dependency used when building documentation.

Removed

- Drop support for Python 3.7 due to end-of-life on 27 June 2023.
- Removed deprecated pypi package [codecov](https://github.com/codecov/codecov-python) from Tox configuration. (#74)
Discussion at: <https://community.codecov.com/t/codecov-yanked-from-pypi-all-versions/4259>.

Changed

- Updated tool plugins to match new structure introduced in sscpac/statick423.

Fixed

- Pin flake8<5 and pycodestyle<2.9.0 until <https://github.com/tholo/pytest-flake8/issues/87> is fixed.

Removed

- Drop support for Python 3.6 due to end-of-life of that distribution.
See <https://endoflife.date/python>.
To continue using Statick with Python 3.6 [pin the version](https://pip.pypa.io/en/stable/user_guide/)
used to the `0.1` tags.
An example is at the discussion at <https://github.com/sscpac/statick/discussions/376>.

Added

- Add Python 3.10 support.
- Add plugin for VAL Parser tool from King's College London.
- Switch type hints from comment style to inline style.
- Switch workflow testing from local installed Statick to
[Statick GitHub Action](https://github.com/sscpac/statick-action).

Fixed

- Use quotes for version numbers in YAML to avoid truncating trailing zeros.
- Do not fail workflow if Codecov results are not uploaded successfully.
That step is too brittle and fails intermittently.

Added

- Add testing support for Python 3.10.
- Add weekly scheduled test actions to identify issues on a consistent basis.
This will catch bugs related to updated dependencies when the code is not modified.

Fixed

- Fixed a bug in the stock planning configuration file.
The name of the tool plugin in the configuration file was not updated to reflect the renamed plugin.
- Fixed pylint warnings related to using the open call without specifying an encoding.

Removed

- No longer supporting Ubuntu 16.04.
- No longer supporting Python 3.5.

Added

- Use new Statick feature of walking directory structure once per package for discovery phase.

Changed

- Convert use of print() and show tool output flags to the built-in Python logging module.
- Rename `val` tool plugin to `val_validate`.
This matches the actual utility name, and provides room to add other utilities from the VAL project.
