The ANSI project is a superlative collection of ANSI escape code related libraries eabling ANSI colorization and stylization of console output. Byte for byte ANSI is the best ANSI code library available for the Ruby programming language.

The Hashery is a tight collection of Hash-like classes. Included among its many offerings are the auto-sorting Dictionary class, the efficient LRUHash, the flexible OpenHash and the convenient KeyHash. Nearly every class is a subclass of the CRUDHash which defines a CRUD model on top of Ruby's standard Hash making it a snap to subclass and augment to fit any specific use case.

Facets is the premier collection of extension methods for the Ruby programming language. Facets extensions are unique by virtue of thier atomicity. They are stored in individual files allowing for highly granular control of requirements. In addition, Facets includes a few additional classes and mixins suitable to wide variety of applications.

Regex is a simple commmand-line Regular Expression tool that makes it easy to search documents for content matches.

Radix is a very easy to use Ruby library for converting numbers to and from any base. It supports both Integer, Float and Rational numbers, as well as representational string-notations that need not be in ASCII order.

Tapout is a TAP consumer that can take any TAP, TAP-Y or TAP-J stream and output it in a variety of useful formats.

Assertive Expressive is an assertions library specifically designed for reuse by other test frameworks.

Think of Executable as a *COM*, a Commandline Object Mapper, in much the same way that ActiveRecord is an ORM, an Object Relational Mapper. A class utilizing Executable can define a complete command line tool using nothing more than Ruby's own method definitions.

Finder is a general purpose file finder for Ruby. Finder can search RubyGems, Roll libraries and Ruby's standard $LOAD_PATH and system data directory for the active or the most current library files. It is especially useful for implementing library-based plugin systems.

Instance is a spin-off of Ruby Facets. It provides a simple convenient API for accessing an object's state.

Lemon is a unit testing framework that tightly correlates class to test case and method to test unit.

MiniTap provides a MiniTest TAP-Y/J report format suitable for use with TAPOUT.

OStruct2 is a reimplementation of Ruby's standard ostruct.rb library. This new OpenStruct class addresses issues the original has with conflicting member names and cloning.

Parametric Mixins provides parameters for mixin modules.

Rubytest is a universal test harness for Ruby. It can handle any compliant test framework, even running tests from multiple frameworks in a single pass. This is the core component of the system, and is the only part strictly necessary to run tests.

YAML Command provides a command line interface to teasing apart and reconstructing YAML files.

Anise is an annotations systems for the Ruby programming lanaguage.

Assay defines assertions in the same way that Ruby defines exceptions. Each type of asserition, called an assay, is then a child of the base Assertion class, which itself is a subclass of the Exception class.

Assay MiniTest defines a set of MiniTest-compatible assertion and extension method which seemlessly delegate on Assay assertions. This allows developers to change test frameworks without having to completely rewrite a slew of previously written MiniTest-based tests and/or sepcifications.

Assay TestUnit defines a set of TestUnit-compatible assertion methods which depend on Assay's assertion classes. This allows developers to change test frameworks without having to change a slew of previously defined assertions.
