FORTRAN Unit Test Framework (FRUIT)
FORTRAN Unit Test Framework FRUIT - TDD in FORTRAN
FORTRAN Unit Test Framework, written in FORTRAN 95. So that all FORTRAN features can be tested. FRUIT has assertion, fixture, setup, teardown, report, spec, driver generation. Rake used as build tool. Tutorials at http://fortranxunit.wiki.sourceforge.net The core testing part is in FORTRAN, this part can be used independent of the Ruby codes. The Ruby code is to make fixtures and reports easier. Rake is to build the project elegantly. This project also demonstrate a new way to build mixed language code in an alternative way than Make. Most of the FORTRAN are important in nature, used in nuclear and aerospace codes, etc, and maintained and written actively. Please help to bring TDD practices to the FORTRAN community. The change could be very hard, personally, I quit, since I could not make the change. I hope your organization will be successful. Enjoy a cup of fruit while maintaining FORTRAN !

Capistrano
Remote multi-server automation tool
A remote server automation and deployment tool written in Ruby. Capistrano extends the Rake DSL with methods specific to running commands on() servers. Capistrano is written in Ruby, but it can easily be used to deploy any language. If your language or framework has special deployment requirements, Capistrano can easily be extended to support them. Capistrano is bundled as a Ruby Gem. It requires Ruby 2.0 or newer. Capistrano can be installed as a standalone Gem, or bundled into your application. It is recommended to fix the version number when using Capistrano, and is therefore recommended to use an appropriate bundler. The capistrano-rails gem includes extras specifically designed for Ruby on Rails, specifically Asset Pipeline Support and Database Migration Support. Capistrano deploys using SSH. Thus, you must be able to SSH (ideally with keys and ssh-agent) from the deployment system to the destination system for Capistrano to work. -

Chromebrew
Package manager for Chrome OS
The Missing Package Manager For Chrome OS. Chromebooks with ChromeOS run a Linux kernel. The only missing pieces to use as a full-featured Linux distro were gcc and make with their dependencies. Well, these pieces aren't missing anymore. Say hello to Chromebrew. In fact, Chromebrew is a simple Ruby script. There's also some Git involved, so we needed both of these things to run it on a bare Chrome OS. We have prebuilt them along with their dependencies to install into your system during installation. So, basically, after installing Chromebrew, you will have fully functional Ruby with Rubygems, Git, and a package manager dedicated just to your Chromebook. -

Concurrent Ruby
Modern concurrency tools including agents, futures, promises, etc.
Modern concurrency tools including agents, futures, promises, thread pools, supervisors, and more. Inspired by Erlang, Clojure, Scala, Go, Java, JavaScript, and classic concurrency patterns. Concurrent Ruby is an 'unopinionated' toolbox that provides useful utilities without debating which is better or why. It remains free of external gem dependencies. It stays true to the spirit of the languages providing inspiration, but implements in a way that makes sense for Ruby. Keeps the semantics as idiomatic Ruby as possible, supports features that make sense in Ruby. Excludes features that don't make sense in Ruby. It is small, lean, and loosely coupled, thread-safety, and with backward compatibility. Concurrent Ruby makes one of the strongest thread safety guarantees of any Ruby concurrency library, providing consistent behavior and guarantees on all four of the main Ruby interpreters (MRI/CRuby, JRuby, Rubinius, TruffleRuby). -

Discourse
A platform for community discussion. Free, open, simple
Discourse is a modern, open-source discussion platform that rethinks forum software with an emphasis on civilized, long-lived conversations and community moderation at scale. It replaces dated bulletin-board paradigms with features like real-time updates, infinite scrolling, rich text composition, and progressive trust levels that let communities delegate moderation as members demonstrate good behavior. On the administrative side, Discourse provides powerful moderation tools—flagging, bulk actions, user silencing, and automated throttles—plus robust spam defenses and analytics to surface community health signals. The platform is extensible: a plugin system and well-documented APIs let organizations add integrations (SSO, chat bridges, badges, embeds) and tailor behavior without hacking core code. -

Errbit
The open source error catcher that's Airbrake API compliant
Errbit is a tool for collecting and managing errors from other applications. It is Airbrake API compliant, so if you are already using Airbrake, you can just point the airbrake gem to your Errbit server. The way Errbit arranges notices into error groups is configurable. By default, Errbit uses the notice's error class, error message, complete backtrace, component (or controller), action and environment name to generate a unique fingerprint for every notice. Notices with identical fingerprints appear in the UI as different occurences of the same error and notices with differing fingerprints are displayed as separate errors. Following the recommendation of 12factor.net, Errbit takes all of its configuration from environment variables. You can use dotenv, which is included in the Gemfile, to fill in any values that you can't or won't supply through the environment. -

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. -

Grape
An opinionated framework for creating REST-like APIs in Ruby
Grape is a Ruby framework for building REST-like APIs with a focus on simplicity and convention. It provides a DSL for declaring endpoints, parameters, formats, and validation rules, making it easy to build consistent and documented APIs. Grape supports multiple content types (JSON, XML, etc.), versioning, error handling, and authentication hooks, which are crucial for maintaining long-lived APIs. It integrates well with frameworks like Rails or Sinatra but can also be used standalone for microservices. Built-in tools like parameter coercion, strong validations, and automatic documentation (via Swagger integrations) reduce boilerplate and improve maintainability. Because it’s lightweight and purpose-built, Grape is popular in service-oriented architectures where clean, well-structured APIs are central. -

Homebrew Cask
CLI workflow for the administration of macOS apps as binaries
Homebrew installs the stuff you need that Apple (or your Linux system) didn’t. Homebrew installs packages to their own directory and then symlinks their files into /usr/local. Homebrew won’t install files outside its prefix and you can place a Homebrew installation wherever you like. Trivially create your own Homebrew packages. It’s all Git and Ruby underneath, so hack away with the knowledge that you can easily revert your modifications and merge upstream updates. Homebrew formulae are simple Ruby scripts. Homebrew complements macOS (or your Linux system). Install your RubyGems with gem and their dependencies with brew. Homebrew Cask installs macOS apps, fonts and plugins and other non-open source software. Making a cask is as simple as creating a formula. -

Lolcat
Rainbows and unicorns
Lolcat is a command-line tool that colorizes terminal output by printing text in rainbow gradients. Inspired by the original Ruby “lolcat” project, it takes input from stdin or files and outputs the same text with colorful ANSI escape codes. It’s frequently used to add a playful touch to logs, help messages, or shell scripts, making otherwise mundane terminal output more fun. Options allow customizing color spread, speed, and randomization to create different rainbow effects. Lolcat is often piped into commands like cat, figlet, or fortune to create whimsical and eye-catching console art. Despite being lighthearted in purpose, it demonstrates the use of ANSI codes and stream manipulation in a clean, portable way. -

Ransack
Object-based searching
Create search forms for your Ruby on Rails application with Ransack! Ransack is available in two modes: simple and advanced, allowing you to create either simple or advanced search forms. Simple mode works much like MetaSearch and is very easy to set up. The advanced mode makes use of Rails' nested attributes functionality in order to generate complex queries with nested AND/OR groupings, etc. This involves more complexity but does produce some very interesting search interfaces and puts more power in the hands of users. Ransack is compatible with Rails 5.0, 5.1, 5.2 and 6.0, and on Ruby 2.3 and later. -

Ruby on Rails
Web Application Framework written in Ruby
Rails is a web application development framework written in the Ruby programming language. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. It allows you to write less code while accomplishing more than many other languages and frameworks. Experienced Rails developers also report that it makes web application development more fun. -

SimpleCov
Code coverage for Ruby with a powerful configuration library
Code coverage for Ruby with a powerful configuration library and automatic merging of coverage across test suites. SimpleCov is a code coverage analysis tool for Ruby. It uses Ruby's built-in Coverage library to gather code coverage data, but makes processing its results much easier by providing a clean API to filter, group, merge, format, and display those results, giving you a complete code coverage suite that can be set up with just a couple lines of code. SimpleCov/Coverage track covered ruby code, gathering coverage for common templating solutions like erb, slim and haml is not supported. In most cases, you'll want overall coverage results for your projects, including all types of tests, Cucumber features, etc. SimpleCov automatically takes care of this by caching and merging results when generating reports, so your report actually includes coverage across your test suites and thereby gives you a better picture of blank spots. -
