Ruby
Ruby programming language
A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming. He has often said that he is “trying to make Ruby natural, not simple,” in a way that mirrors life. Since its public release in 1995, Ruby has drawn devoted coders worldwide. In 2006, Ruby achieved mass acceptance. With active user groups formed in the world’s major cities and Ruby-related conferences filled to capacity. Ruby-Talk, the primary mailing list for discussion of the Ruby language, climbed to an average of 200 messages per day in 2006. It has dropped in recent years as the size of the community pushed discussion from one central list into many smaller groups. -

Linguist
Detect blob languages, suppress generated files and generate graphs
This library is used on GitHub.com to detect blob languages, ignore binary or vendored files, suppress generated files in diffs, and generate language breakdown graphs. Linguist is a Ruby library so you will need a recent version of Ruby installed. There are known problems with the macOS/XCode supplied version of Ruby that causes problems installing some of the dependencies. Accordingly, we highly recommend you install a version of Ruby using Homebrew, rbenv, rvm, ruby-build, asdf or other packaging system, before attempting to install Linguist and the dependencies. Linguist uses charlock_holmes for character encoding and rugged for libgit2 bindings for Ruby. These components have their own dependencies. A repository's languages stats can also be assessed from the command line using the github-linguist executable. Without any options, github-linguist will output the breakdown that correlates to what is shown in the language stats bar. -

Cuprite
Headless Chrome/Chromium driver for Capybara
Cuprite is a Ruby driver for the Capybara testing framework that allows developers to automate browsers using the Chrome DevTools Protocol instead of traditional WebDriver-based tools. It is built on top of the Ferrum library and provides a modern approach to browser automation that removes the need for Selenium or external browser drivers. By communicating directly with Chromium-based browsers through the DevTools protocol, Cuprite enables faster and more reliable browser automation for testing and scraping tasks. The driver integrates seamlessly with Capybara, allowing developers to write feature tests that simulate real user interactions with web applications. Because it uses headless Chrome by default, Cuprite is well suited for automated test environments and continuous integration pipelines. Developers can also run tests with a visible browser window for debugging purposes during development. -

Ferrum
Headless Chrome Ruby API
Ferrum is a Ruby library that provides a high-level API for controlling Chrome or Chromium browsers using the Chrome DevTools Protocol. The project allows developers to automate browser interactions directly without relying on Selenium, WebDriver, or external drivers, which simplifies browser automation workflows. Ferrum runs in headless mode by default but can also be configured to run with a visible browser window for debugging and development purposes. The library communicates directly with Chrome through the DevTools Protocol, providing access to advanced browser functionality such as DOM manipulation, network inspection, and page automation. Because of this low-level access, Ferrum offers greater flexibility and performance compared to traditional WebDriver-based automation tools. It is commonly used for tasks such as web scraping, automated testing, crawling, and screenshot or PDF generation. -

Resque
Ruby library for creating background jobs and processing them
Resque is a Redis-backed Ruby library for creating background jobs, placing them on multiple queues, and processing them later. Resque (pronounced like "rescue") is a Redis-backed library for creating background jobs, placing those jobs on multiple queues, and processing them later. Background jobs can be any Ruby class or module that responds to perform. Your existing classes can easily be converted to background jobs or you can create new classes specifically to do work. Or, you can do both. Resque is heavily inspired by DelayedJob (which rocks) and comprises three parts, a Ruby library for creating, querying, and processing jobs, a Rake task for starting a worker which processes jobs, a Sinatra app for monitoring queues, jobs, and workers. Resque workers can be distributed between multiple machines, support priorities, are resilient to memory bloat / "leaks," are optimized for REE (but work on MRI and JRuby), tell you what they're doing, and expect failure. -

RuboCop
A Ruby static code analyzer and formatter, based on the community Ruby
RuboCop is a Ruby static code analyzer (a.k.a. linter) and code formatter. Out of the box it will enforce many of the guidelines outlined in the community Ruby Style Guide. RuboCop packs a lot of features on top of what you’d normally expect from a linter. Works with every major Ruby implementation. Autocorrection of many of the code offenses it detects. Robust code formatting capabilities. Multiple result for matters for both interactive use and for feeding data into other tools. Ability to have different configurations for different parts of your codebase. Ability to disable certain cops only for specific files or parts of files. Extremely flexible configuration that allows you to adapt RuboCop to pretty much every style and preference. It’s easy to extend RuboCop with custom cops and formatters. Many online services use RuboCop internally (e.g. HoundCI, Sider and CodeClimate). -

RuboCop Rails
A RuboCop extension focused on enforcing Rails best practices
A RuboCop extension focused on enforcing Rails best practices and coding conventions. It’s based on the community-driven Rails style guide. You need to tell RuboCop to load the Rails extension. Now you can run rubocop and it will automatically load the RuboCop Rails cops together with the standard cops. If you are using Rails 6.1 or newer, add the following config.generators.after_generate setting to your config/application.rb to apply RuboCop autocorrection to code generated by bin/rails g. It uses rubocop -A to apply Style/FrozenStringLiteralComment and other unsafe autocorretion cops. rubocop -A is unsafe autocorrection, but code generated by default is simple and less likely to be incompatible with rubocop -A. If you have problems you can replace it with rubocop -a instead. -
