Homebrew tap for Roc.
brew install roc-lang/roc/rocThis installs a prebuilt Roc nightly for macOS 15+ (Apple silicon and Intel) or Linux (x86_64 and arm64).
brew upgrade roc moves you to the newest nightly the tap has picked up.
This tap is an interim solution until Roc has a stable release that can go into homebrew-core.
update.yml checks for a new nightly every three hours.
It only commits the new version to Formula/roc.rb once brew install and brew test pass on all four platforms, so a nightly that is missing a platform or fails to install is skipped.
To pin a specific nightly, run that workflow manually with a tag, or run this locally (needs gh):
