Plugin: updater-homebrew

Updates a Homebrew formula with the new release URL and checksum. Use it when SemRel publishes tarballs that also need to be reflected in a Homebrew tap.

Installation

go install github.com/SemRels/updater-homebrew@latest

Each plugin is a standalone Go binary. Keep it on your PATH or reference it with path: in .semrel.yaml. If you keep secrets in a .env file, load them with semrel --env-file .env release.
