October 28 - November 3, 2024 in Darker: Formatting edge cases and package restructuring

[github-actions[bot]]

There's been a mix of dependency management improvements and bug fixes this week. We're restructuring our package dependencies to make Black optional through a new darker[black] extras option, while keeping it as the default formatter. This change comes with helpful error messages when Black is needed but not installed. A new encoding-related bug was reported (#768) where Darker incorrectly handles files with mixed UTF-8 content and ISO-8859-5 encoding declarations.

Work continues on our documentation efforts with a simplified approach to the Sphinx website generation (PR #766), including automatic deployment on pushes to master. Meanwhile, the work on formatter plugins progresses steadily, with numerous improvements to the Ruff formatter support (#744) and the pyupgrade plugin implementation (#755). Both plugins now handle numeric target versions internally and include comprehensive test coverage. A particularly noteworthy change is that pyupgrade will always process entire files rather than just modified chunks, addressing a technical limitation in the integration.
