Rails is a full-stack framework for developing database-backed web applications according to the Model-View-Control pattern. From the Ajax in the view, to the request and response in the controller, to the domain model wrapping the database, Rails gives you a pure-Ruby development environment. To go live, all you need to add is a database and a web server.

Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in Perl). It is simple, straight-forward, extensible, and portable.

RadRails is an integrated development environment for the Ruby on Rails framework.

The RadRails IDE is built on the Eclipse RCP, and includes the Subclipse plug-in and the RDT plug-ins. The RadRails tools are also available as Eclipse plug-ins.

An enhanced and updated edition of the Ruby Users Guide is now available on the Zamples site.  Building on the work of Yukihiro Matsumoto, GOTO Kentaro, Julian Fondren, Mark Slagell and Dave Thomas, this new edtion features live online code examples embedded into the documentation and more examples than the previous edition.  All of the code examples work in a web browser without requiring the user to install any software.  The Zamplized Ruby Users Guide is freely available for browsing at http://zamples.com/rubyUG/ and can be downloaded in its entirety at no charge according to the terms of the LGPL.

For the first time, the Zamplized Ruby Users Guide takes advantage of a new Zamples capability, a single-step tracing facility.  With the trace, the result of evaluating each line of the program can be displayed.  Currently Zamples only supports the Ruby language with this facility.
