nio provides cross-platform asynchronous I/O primitives in Ruby for scalable network clients and servers.

EventMachine implements a single-threaded engine for arbitrary network communications. EventMachine wraps all interactions with sockets, allowing programs to concentrate on the implementation of network protocols. It can be used to create both network servers and clients.

Hoe is a rake/rubygems helper for project Rakefiles. It helps manage, maintain, and release projects and includes a dynamic plug-in system allowing for easy extensibility. Hoe ships with plug-ins for all the usual project tasks including rdoc generation, testing, packaging, deployment, and announcement.

These Ruby bindings are not intended to be directly used, but rather used by higher level bindings like those provided by CZTop.

Coderay is a Ruby library that provides syntax highlighting for select languages.

This library allows reading and writing RPM packages. It is used by the fpm tool. It is written in pure Ruby because librpm is not available on all systems and requires many dependencies.

This package provides a MiniTest plugin for displaying the slowest tests in a minitest suite.

Ruby-Locale is the pure ruby library which provides basic APIs for localization.

TestConstruct is a DSL for creating temporary files and directories during tests.

This package provides memory profiling routines for Ruby.

This package provides a plugin for the RuboCop code style enforcing & linting tool.

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.

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.

This package containse the XML parsing tools shared between a number of providers in the fog gem. fog is a Ruby cloud services library.

Inspired by Electric XML library for Java, REXML aims to be easy-to-use API, small and fast. It supports both tree and stream document parsing.

Ruby C bindings to the Yajl JSON stream-based parser library. The API is compatible with the JSON gem, so yajl-ruby can act as a drop in replacement.

A modified copy of yajl is used, and included in the package.

Cutest runs tests in separate processes to avoid shared state.

RubyMoney provides a library for dealing with money and currency conversion. Its features are:

• Provides a Money class which encapsulates all information about a certain amount of money, such as its value and its currency.

• Provides a Money::Currency class which encapsulates all information about a monetary unit.

• Represents monetary values as integers, in cents; so avoids floating point rounding errors.

• Represents currency as Money::Currency instances providing a high level of flexibility.

• Provides APIs for exchanging money from one currency to another.

Backports enables more compatibility across Ruby versions by providing backports of some features.

OpenURI with transparent disk caching, which is useful to avoid making excessive queries, for example when scraping web pages.

Pry is an IRB alternative and runtime developer console for Ruby. It features syntax highlighting, a plugin architecture, runtime invocation, and source and documentation browsing.

This package provides a set of Hoe plugins for tighter Git integration. It provides tasks to automate release tagging and pushing and changelog generation.

This package provides a collection of text algorithms: Levenshtein, Soundex, Metaphone, Double Metaphone, Porter Stemming.

AnyStyle is a very fast and smart parser for academic reference lists and bibliographies. AnyStyle uses powerful machine learning heuristics based on Conditional Random Fields and aims to make it easy to train the model with data that is relevant to your parsing needs.

This package provides the Ruby module AnyStyle. AnyStyle can also be used via the anystyle command-line utility or a web application, though the later has not yet been packaged for Guix.
