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

👣 How will this project approach the September 2025 hostile takeover of RubyGems? 🚑️

I've summarized my thoughts in this blog post.

Compatibility

Compatible with MRI Ruby 3.2.0+, and concordant releases of JRuby, and TruffleRuby. CI workflows and Appraisals are generated for MRI Ruby 3.2.0+. 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.

✨ Installation

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

bundle add rubocop-lts-rspec

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

gem install rubocop-lts-rspec

⚙️ Configuration

🔧 Basic Usage

Via rubocop-lts gem

After adding both this gem and rubocop-lts to your Gemfile or gemspec, utilize a config provided by rubocop-lts. The configs that end in *_rspec.yml will pull in all the config from this gem, specifically for the version of Ruby indicated by the version of rubocop-lts you are on.

With Plain Ruby:

inherit_gem:
    rubocop-lts: config/ruby_rspec.yml

With RubyGem:

inherit_gem:
    rubocop-lts: config/rubygem_rspec.yml

With Rails:

inherit_gem:
    rubocop-lts: config/rails_rspec.yml

Via rubocop-ruby#_# gem

After adding both this gem and rubocop-ruby#_# to your Gemfile or gemspec, utilize a config provided by rubocop-ruby#_#. The configs that end in *_rspec.yml will pull in all the config from this gem, specifically for the version of Ruby indicated by the version of rubocop-ruby#_# you are on.

For this example we will use the rubocop-ruby3_2 gem. Replace only the gem name key if you are using a different one:

With Plain Ruby:

inherit_gem:
  rubocop-ruby3_2: rubocop-lts/ruby_rspec.yml

With RubyGem:

inherit_gem:
  rubocop-ruby3_2: rubocop-lts/rubygem_rspec.yml

With Rails:

inherit_gem:
  rubocop-ruby3_2: rubocop-lts/rails_rspec.yml

Standalone

If you are using this gem standalone, add to the top of your project's .rubocop.yml configuration file:

inherit_gem:
  # Replace {RUBY_MAJOR_VERSION} with the minimum major version of ruby you want to target.
  # Replace {RUBY_MINOR_VERSION} with the minimum minor version of ruby you want to target.
  rubocop-lts-rspec: config/ruby-{RUBY_MAJOR_VERSION}-{RUBY_MINOR_VERSION}.yml
What will this do for me?

Among other potential settings specific to your chosen minimum version of ruby, the above effectively results in the following config (& more):

inherit_mode:
  merge:
    - Exclude
    - Include

require:
  - rubocop-lts-rspec
  - rubocop-factory_bot
  - rubocop-rspec-extra
  - rubocop-env
  - rubocop-rspec

inherit_gem:
  rubocop-env: config/default.yml
  rubocop-rspec-extra: config/default.yml

RSpec/Focus: # run ALL tests on CI
  Enabled: true
  Exclude: []

Lint/Debugger: # don't leave binding.pry
  Enabled: true
  Exclude: [ ]

What about TargetRubyVersion?

It will be set up for you, when you follow any of the above setup instructions.

🦷 FLOSS Funding

While rubocop-lts tools are free software and will always be, the project would benefit immensely from some funding. Raising a monthly budget of... "dollars" would make the project more sustainable.

We welcome both individual and corporate sponsors! We also offer a wide array of funding channels to account for your preferences. Currently, Open Collective is our preferred funding platform.

If you're working in a company that's making significant use of rubocop-lts tools we'd appreciate it if you suggest to your company to become a rubocop-lts sponsor.

You can support the development of rubocop-lts tools via GitHub Sponsors, Liberapay, PayPal, Open Collective and Tidelift.

📍 NOTE
If doing a sponsorship in the form of donation is problematic for your company
from an accounting standpoint, we'd recommend the use of Tidelift,
where you can get a support-like subscription instead.

Open Collective for Individuals

Support us with a monthly donation and help us continue our activities. [Become a backer]

Another way to support open-source

I’m driven by a passion to foster a thriving open-source community – a space where people can tackle complex problems, no matter how small. Revitalizing libraries that have fallen into disrepair, and building new libraries focused on solving real-world challenges, are my passions. I was recently affected by layoffs, and the tech jobs market is unwelcoming. I’m reaching out here because your support would significantly aid my efforts to provide for my family, and my farm (11 🐔 chickens, 2 🐶 dogs, 3 🐰 rabbits, 8 🐈‍ cats).

If you work at a company that uses my work, please encourage them to support me as a corporate sponsor. My work on gems you use might show up in bundle fund.

I’m developing a new library, floss_funding, designed to empower open-source developers like myself to get paid for the work we do, in a sustainable way. Please give it a look.

📌 Versioning

This library follows Semantic Versioning 2.0.0 for its public API where practical. For most applications, prefer the Pessimistic Version Constraint with two digits of precision.

For example:

spec.add_dependency("rubocop-lts-rspec", "~> 1.0")
📌 Is "Platform Support" part of the public API? More details inside.

Dropping support for a platform can be a breaking change for affected users. If a release changes supported platforms, it should be called out clearly in the changelog and versioned with that impact in mind.

To get a better understanding of how SemVer is intended to work over a project's lifetime, read this article from the creator of SemVer:

See CHANGELOG.md for a list of releases.

🤑 A request for help

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.
