Octokit wraps the GitHub API in a flat API client that follows Ruby conventions and requires little knowledge of REST.

Spectroscope is a Behavior-Driven Development (BDD) framework built on RubyTest, designed to emulate RSpec in most respects. It is assertion framework independent so any number of assertion systems can be used, such as Assay or AE.

Text::Hyphen is a Ruby library to hyphenate words in various languages using Ruby-fied versions of TeX hyphenation patterns. It will properly hyphenate various words according to the rules of the language the word is written in. The algorithm is based on that of the TeX typesetting system by Donald E. Knuth.

Haml is a layer on top of HTML or XML that is designed to express the structure of documents using indentation rather than closing tags. It was originally envisioned as a plugin for Ruby on Rails, but it can function as a stand-alone templating engine.

Covered uses modern Ruby features to generate comprehensive coverage, including support for templates which are compiled into Ruby. It has the following features:

• Incremental coverage -- if you run your full test suite, and the run a subset, it will still report the correct coverage - so you can incrementally work on improving coverage.

• Integration with RSpec, Minitest, Travis & Coveralls - no need to configure anything - out of the box support for these platforms.

• It supports coverage of views -- templates compiled to Ruby code can be tracked for coverage reporting.

RubyPants is a Ruby port of the smart-quotes library SmartyPants. The original SmartyPants is a web publishing plug-in for Movable Type, Blosxom, and BBEdit that easily translates plain ASCII punctuation characters into smart typographic punctuation HTML entities.

Lemon is a unit testing framework that enforces highly formal case-to-class and unit-to-method test construction. This enforcement can help focus concern on individual units of behavior.

pry-stack_explorer is a plugin for the Pry REPL that add support to navigate the call-stack.

This gem generates a treemap showing the complexity of Ruby code on which it is run. It uses Saikuro under the covers to analyze Ruby code complexity.

Optimized XML (Ox) is a fast XML parser and object serializer for Ruby written as a native C extension. It was designed to be an alternative to Nokogiri and other Ruby XML parsers for generic XML parsing and as an alternative to Marshal for Object serialization.

This Ruby library is controlling and communicating with spawned processes. It is designed after Python's subprocess module.

This small library lets you see which property values are supported by the regular expression engine of the Ruby version you are running and can directly read out their code point ranges. In other words, it determines all supported values for \pvalue expressions and what they match.

Saikuro is a Ruby cyclomatic complexity analyzer. When given Ruby source code Saikuro will generate a report listing the cyclomatic complexity of each method found. In addition, Saikuro counts the number of lines per method and can generate a listing of the number of tokens on each line of code.

Metaclass is a Ruby library adding a metaclass method to all Ruby objects.
