A toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Rich support for multibyte strings, internationalization, time zones, and testing.

Hashie is a collection of classes and mixins that make hashes more powerful.

Docile treats the methods of a given ruby object as a DSL (domain specific language) within a given block. Killer feature: you can also reference methods, instance variables, and local variables from the original (non-DSL) context within the block. Docile releases follow Semantic Versioning as defined at semver.org.

A few useful extensions to core Ruby classes.

Provides a C-optimized method for determining if a string is blank

Efficient, immutable, thread-safe collection classes for Ruby

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.

Support library for Merb

RubyTree is a Ruby implementation of the generic tree data structure. It provides simple APIs to store named nodes, and to access, modify, and traverse the tree. The data model is node-centric, where nodes in the tree are the primary structural elements. It supports all common tree-traversal methods (pre-order, post-order, and breadth first). RubyTree mixes in the Enumerable and Comparable modules and behaves like a standard Ruby collection (iteration, comparison, etc.). RubyTree also includes a binary tree implementation, which provides in-order node traversal besides the other methods. RubyTree can import from and export to JSON, and supports Ruby’s object marshaling.

tells you which method does the thing you want to do

DEPRECATED! Please use the sugar refinery: http://github.com/janlelis/sugar_refinery

A Scala-inspired Monad library for Ruby, aiming to share the most common idioms for folks working in both languages. Includes Option, Array, etc.

Provides a C-optimized method for underscoring a string

PluginFactory is a mixin module that turns an including class into a factory for its derivatives, capable of searching for and loading them by name. This is useful when you have an abstract base class which defines an interface and basic functionality for a part of a larger system, and a collection of subclasses which implement the interface for different underlying functionality. An example of where this might be useful is in a program which talks to a database. To avoid coupling it to a specific database, you use a Driver class which encapsulates your program's interaction with the database behind a useful interface. Now you can create a concrete implementation of the Driver class for each kind of database you wish to talk to. If you make the base Driver class a PluginFactory, too, you can add new drivers simply by dropping them in a directory and using the Driver's `create` method to instantiate them:

A collection of helpful methods and monkey patches for Objects, Strings, Enumerables, Arrays, Hash, Dates, Minitest & Rails

This gem simulates named-parameters in Ruby. It's a complement to the common Ruby idiom of using Hash args to emulate the use of named parameters.

DeepTree simplifies fetching deeply nested nodes in Ruby hashes.

A tiny Ruby gem to provide the 'scan_left' operation on any Ruby Enumerable.

Allows extending ruby's syntax and compilation process

Extends Vernacular to support rewriting the AST

Provides a C-optimized method for camelizing a string

a lightweight core and extra extensions for Ruby.
