publish-gem-to-github

Release your Ruby Gem to GitHub Packages, RubyGems.org, and Gem.coop with ease. This action is a fast, lightweight composite action that defaults to Ruby 4.0.

Why use this?

• Fast: Composite action runs directly on the host, avoiding Docker overhead.
• Multi-Registry: Support for GitHub Packages, RubyGems.org, and Gem.coop.
• Simple: Just add your API keys to enable pushing to each registry.
• Modern: Defaults to Ruby 4.0 but supports any version via input.
