Statick

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.

Added

- Discovery plugin to find PDDL files.
The files are sorted into domain and problem file types based on the contents of the file.
- Tool plugin for the `Validate` application from
[VAL](https://github.com/KCL-Planning/VAL/tree/master/applications#validate).
`Validate` is a utility to check the syntax of PDDL files.
In order to use the tool a domain file is required to have been discovered, and a problem file is optional.

Added

- Add Python 3.10 support. (Thomas Denewiler, tdenewiler, 48)
- Add weekly tests and a manual trigger to the test workflow.
- Switch testing environment from macos-latest to macos-10.15.
This is to retain support for Python 3.6. (Thomas Denewiler, tdenewiler, 46)

Fixed

- Switch use of codecov-action from v1 to v2 for increased stability when uploading reports.
(Thomas Denewiler, tdenewiler, 45)
- Use quotes for version numbers in YAML to avoid truncating trailing zeros. (Thomas Denewiler, tdenewiler, 48)
- Fix proselint tests by changing exclamation point to a period in test Markdown files. (Thomas Denewiler, tdenewiler, 50)
