Good morning, this is your Homebrew development briefing for May 15th, 2026.
MikeMcQuaid merged "Move API checks into RuboCop," a significant refactoring that consolidates public API validation into Homebrew's existing code style infrastructure. The change removes a 94-line CI-only script and integrates API checks directly into the `brew style` command that contributors already run locally.
The pull request modified eight files, adding 154 lines while removing 104. Key changes include enhanced RuboCop cops for public API cookbook and documentation validation, along with expanded test coverage. The GitHub Actions workflow was simplified by removing the separate API check step.
This consolidation means API validation failures will now surface earlier in the development process, before code reaches the continuous integration pipeline. Previously, contributors might not discover API issues until after pushing their changes, creating additional review cycles.
The merge also ties cookbook and documentation checks directly to their respective RuboCop rules, creating a more cohesive validation system. Test files were expanded to cover the new functionality, with 45 new lines in the cookbook spec and 30 in the documentation spec.
What's next: Contributors will immediately benefit from catching API issues locally during style checks. The simplified CI workflow should reduce build times and improve the overall development experience.
That's your Homebrew update for today. Back tomorrow with more development news.
