Statick-tex

Changed

- Updated tool plugins to match new structure introduced in sscpac/statick423.
- Use Statick action v0.0.2 instead of main.

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 `0.2` tags.
An example is at the discussion at <https://github.com/sscpac/statick/discussions/376>.

Added

- Add Python 3.10 support.
- Add scheduled weekly workflow run.
- Add ability to manually trigger workflow run for any branch.
- 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

- Fix pylint warnings related to using the open call without specifying an encoding.
- Switch to Pythonic way of checking that a variable is not equal to more than one value (fixes pylint warning).
- Use quotes for version numbers in YAML to avoid truncating trailing zeros.
- Switch use of codecov-action from v1 to v2 for increased stability when uploading reports.
- Do not fail workflow if Codecov results are not uploaded successfully.
That step is too brittle and fails intermittently.

Removed

- Remove support for Ubuntu 16.04 and Python 3.5.

Changed

- Convert use of print() and show tool output flags to the built-in Python logging module.

Added

- Python 3.9 is now supported and tested.
- Use new discovery plugin cache of file information instead of walking the package directory structure
independently.
Provides large speed improvement in discovery phase (about 3x faster). (Alexander Xydes, xydesa)

Added

- Documentation is generated and published to GitHub Pages on new tags.
- Tests are run on Ubuntu 16.04, 18.04, and 20.04 in addition to previous operating systems.
- The `--strict` flag is used for Mypy.
- Markdown linting using statick-md.

Fixed

- Tox configuration updated so that unit tests continue working.
- Limit discovery plugins that are run on default levels to speed up Statick.
