Knows about MRI, Rubinius, JRuby, MagLev and MacRuby.

A Ruby gem for tokenizing, parsing, and transforming regular expressions. It comprises the following components:

• A scanner/tokenizer based on Ragel,

• A lexer that produces a stream of token objects,

• A parser that produces a tree of Expression objects.

Antwrap is a Ruby module that wraps the Apache Ant build tool. Antwrap can be used to invoke Ant tasks from a Ruby or a JRuby script.

Given a string pattern, Mustermann will turn it into an object that behaves like a regular expression and has comparable performance characteristics.

This package provides a Ruby library to handle the WebSocket protocol.

This gem provide built-in support for the Sass converter in Jekyll.

Multipart-Post Adds multipart POST capability to Ruby's net/http library.

The sys-filesystem library provides a cross-platform interface for gathering file system information, such as disk space and mount points.

Capybara is an integration testing tool for rack based web applications. It simulates how a user would interact with a website.

Debugging functionality for Ruby. This is completely rewritten debug.rb which was contained by the ancient Ruby versions. It is included with Ruby itself, but this package is made available so that the latest version can be made available independently from Ruby.

This package provides C extensions to optimize the concurrent-ruby gem when running under the Matz's Ruby Interpreter (MRI, also known as CRuby).

This package provides a set of parsers for Accept and Accept-Language HTTP headers.

jaro_winkler is an implementation of Jaro-Winkler distance algorithm. It is written as a C extension and will fallback to a pure Ruby implementation on platforms where this is unsupported.

Prawn::Icon provides various icon fonts including FontAwesome, PaymentFont and Foundation Icons for use with the Prawn PDF toolkit.

Timeout provides a way to auto-terminate a potentially long-running operation if it hasn't finished in a fixed amount of time.

The SafeYAML gem provides an alternative implementation of YAML.load suitable for accepting user input in Ruby applications.

This library contains the Ruby extension that implements Protocol Buffers functionality in Ruby.

The Ruby extension makes use of generated Ruby code that defines message and enum types in a Ruby DSL. You may write definitions in this DSL directly, but we recommend using protoc's Ruby generation support with .proto files. The build process in this directory only installs the extension; you need to install protoc (in package ruby-grpc-tools) as well to have Ruby code generation functionality.

Sentry-Core provides a gem that provides a client interface for the Sentry error logger.

Power-assert is an assertion library providing descriptive assertion messages for tests.

Parallel allows you to run any code in parallel Processes (to use all CPUs) or Threads(to speedup blocking operations). It is best suited for map-reduce or e.g. parallel downloads/uploads.

mkmf-lite is a light version of Ruby's mkmf.rb designed for use as a library. It does not create packages, builds, or log files of any kind. Instead, it provides mixin methods that you can use in FFI or tests to check for the presence of header files, constants, and so on.
