Ruby Bundler Support	Ruby Bundler support in Renovate

Automated Dependency Updates for Ruby Bundler Dependencies

Renovate supports upgrading dependencies in Bundler's Gemfiles and their accompanying Gemfile.lock files. Support is considered "alpha" stage until there have been some more real-world tests.

How It Works

1. Renovate will search each repository for any Gemfile files
2. Existing dependencies will be extracted from the files
3. Renovate will resolve the dependency on Rubygems or elsewhere if configured, and look for any newer versions
4. A PR will be created with Gemfile and Gemfile.lock updated in the same commit
5. If the source repository has either a "changelog" file or uses GitHub releases, then Release Notes for each version will be embedded in the generated PR

Enabling

Either install the Renovate App on GitHub, or check out Renovate OSS for self-hosted. Bundler support is now enabled by default in both.

Future work

• Updating .gemspec files
• Pinning dependencies to the version found in Gemfile.lock rather than the latest matching version
• Lock file maintenance
• Selective lock file updating (if ranges are in use in the Gemfile)
