Pull request overview
This PR enhances the cache-homebrew-prefix action with two main features: automatic cleanup of existing formulae via brew test-bot --only-cleanup-before when uninstall=true, and support for installing formulae from a Brewfile using brew bundle.
Changes:
- Added
uninstallinput to automatically remove existing formulae before installation - Added
brewfileinput to support installation from a./Brewfileinstead of specifying individual formula names - Changed behavior to only check for formulae (not casks), making the action more flexible
- Made the
installinput optional (with mutual exclusivity betweeninstallandbrewfileenforced)
