💎 Kettle::Deps::Floor

if ci_badges.map(&:color).detect { it != "green"} ☝️ let me know on Discord or RubyForum, as I may have missed the notification.

if ci_badges.map(&:color).all? { it == "green"} 👇️ send money so I can do more of this. FLOSS maintenance is now my full-time job.

kettle-deps-floor discovers the minimum dependency versions already supported by your Ruby gems and raises their declared floors when newer versions are safe to use. It can inspect gemspecs and configured template sources, with upgrade limits, dry-run reports, checks, and controlled commits.

Compatible with MRI Ruby 3.2.0+, JRuby, and TruffleRuby. CI workflows and Appraisals are generated for MRI Ruby 3.2.0+. The current MRI CI lane runs on Linux and macOS. This test floor is configured by ruby.test_minimum in .kettle-jem.yml and may be higher than the gem's runtime compatibility floor when legacy Rubies are not practical for the current toolchain.

The amazing test matrix is powered by the kettle-dev stack.

Other support channels:

Install the gem and add to the application's Gemfile by executing:

bundle add kettle-deps-floor

If bundler is not being used to manage dependencies, install the gem by executing:

gem install kettle-deps-floor

By default, kettle-deps-floor scans *.gemspec in the selected project root and queries RubyGems for newer compatible versions. A project may add .kettle-deps-floor.yml to configure source globs, explicit family-release versions, and dependency holds:

sources:
  - "*.gemspec"
  - "Gemfile"
target_versions:
  token-resolver: "2.0.14"
holds:
  rubocop-minitest: "Wait until the standard gem range permits this release."

target_versions is useful for sibling-family lockstep releases. Holds suppress a named dependency from automatic updates. Use quoted version strings.

Preview compatible dependency-floor updates without changing files:

bundle exec kettle-deps-floor --upgrade patch

Check a family member against an explicit just-released sibling version:

bundle exec kettle-deps-floor --check --target token-resolver=2.0.14

Apply updates, add a keyed Unreleased changelog entry, and commit only the changed source files (the default write behavior):

bundle exec kettle-deps-floor --write --upgrade minor

Use --no-commit to write without committing, --no-changelog to omit the changelog update, --source GLOB to add or override scanned Ruby source paths, and --only GEM[,GEM...] to limit the update set. The major, minor, and patch limits constrain registry candidates; existing non-floor requirements are still checked before a target is accepted. Changes use Prism AST source locations rather than text substitutions.

Use --events to stream compact NDJSON progress events to stdout; the normal human summary moves to stderr so the stream remains machine-readable. Events use kettle-ndjson's versioned run_start, command_step, and summary schema.

See SECURITY.md.

If you need some ideas of where to help, you could work on adding more code coverage, check issues or PRs, or use the gem and think about how it could be better.

We so if you make changes, remember to update it.

This library follows for its public API where practical. For most applications, prefer the Pessimistic Version Constraint with two digits of precision.

For example:

spec.add_dependency("kettle-deps-floor", "~> 0.0")

Maintainers have teeth and need to pay their dentists. After getting laid off in an RIF in March, and encountering difficulty finding a new one, I began spending most of my time building open source tools. I'm hoping to be able to pay for my kids' health insurance this month, so if you value the work I am doing, I need your support. Please consider sponsoring me or the project.
