Setup Homebrew Github Action

An action that sets up a Homebrew environment.

Runs on ubuntu and macos.

Usage

- name: Set up Homebrew
  id: set-up-homebrew
  uses: Homebrew/actions/setup-homebrew@master

This also sets up the variables necessary to cache the gems installed by Homebrew developer commands (e.g. brew style). To use these add:

- name: Cache Homebrew Bundler RubyGems
  id: cache
  uses: actions/cache@v3
  with:
    path: ${{ steps.set-up-homebrew.outputs.gems-path }}
    key: ${{ runner.os }}-rubygems-${{ steps.set-up-homebrew.outputs.gems-hash }}
    restore-keys: ${{ runner.os }}-rubygems-

- name: Install Homebrew Bundler RubyGems
  if: steps.cache.outputs.cache-hit != 'true'
  run: brew install-bundler-gems

Note you do not need to use the actions/setup-ruby or actions/checkout steps because this action will install the necessary Ruby for Homebrew and checkout the repository being tested.
