April 21-28, 2024 in Darker: Configuration fixes and ongoing discussions

[akaihola]

This week saw improvements in Darker's configuration handling and continued discussions on various issues. We merged a fix to correctly display the configuration section name when using the -vv option (PR #586). This change ensures that the output now shows [tool.darker] instead of [tool.darkgraylib], providing a more accurate representation of Darker's configuration.

We also revisited some older issues, including a potential problem with pre-commit hooks returning non-zero exit codes even when there are no linting errors (Issue #390). The community is investigating whether recent changes in Graylint, which Darker now uses for linting support, might have resolved this issue. Ongoing discussions include exploring the use of Black's --preview option for early warnings about style changes (Issue #457) and improving documentation with Git diagrams to illustrate the --revision argument variations (Issue #326). We're also considering the use of Dependabot for updating dependencies and GitHub Action versions (Issue #341) to streamline our maintenance process.

Another open issue being addressed is Darker's handling of blank lines re-inserted by Black where a user had only deleted lines (Issue #371). This highlights the complex interactions between Darker and Black's formatting choices, and we're working on developing a minimal test case and a fix for this behavior.
