Adds a Redis::Namespace class which can be used to namespace calls to Redis. This is useful when using a single instance of Redis with multiple, different applications.

The purpose of this library is to help move the terminal cursor around and manipulate text by using intuitive method calls.

This pure Ruby library can read and write PNG images without depending on an external image library, like RMagick. It tries to be memory efficient and reasonably fast. It supports reading and writing all PNG variants that are defined in the specification, with one limitation: only 8-bit color depth is supported. It supports all transparency, interlacing and filtering options the PNG specifications allows. It can also read and write textual metadata from PNG files. Low-level read/write access to PNG chunks is also possible. This library supports simple drawing on the image canvas and simple operations like alpha composition and cropping. Finally, it can import from and export to RMagick for interoperability. Also, have a look at OilyPNG at https://github.com/wvanbergen/oily_png. OilyPNG is a drop in mixin module that implements some of the ChunkyPNG algorithms in C, which provides a massive speed boost to encoding and decoding.

Provides a better error page for Rails and other Rack apps. Includes source code inspection, a live REPL and local/instance variable inspection for all stack frames.

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

Capybara aims to simplify the process of integration testing Rack applications, such as Rails, Sinatra or Merb. It is inspired by and aims to replace Webrat as a DSL for interacting with a webapplication. It is agnostic about the driver running your tests and currently comes bundled with rack-test, Culerity, Celerity and Selenium support built in.
