Celerity is a JRuby wrapper around HtmlUnit – a headless Java browser with JavaScript support. It provides a simple API for programmatic navigation through web applications. Celerity aims at being API compatible with Watir.

Reittiopas is a Ruby library for accessing the [Reittiopas Developer API](http://developer.reittiopas.fi/pages/fi/reittiopas-api.php). Requires an account to the service that can be requested through [the account request page](http://developer.reittiopas.fi/pages/fi/accountrequest.php).

Rejuicer.

The relative library enhances Ruby's core and standard libraries to support naming, opening, and reading files relative to the Ruby file currently being interpreted (the contents of the __ FILE __ identifier). This functionality is especially useful in embedded Ruby (eruby, erb, erubis, etc.) where absolute paths or paths relative to the interpreter's current working directory are problematic (due to file system structures and working directories varying across platforms and web servers).

It's metastable

Provides single sign on for web applications using the CAS protocol.

Provides a basic framework for easily creating classes that access remote APIs.

Remote require capabilities.

R'epertoire is a Ruby library for quickly checking-out and updating code-bases from various SCMs. R'epertoire currently supports Subversion, Git, Mercurial and even RSync.

Real Estate Price change module for the Netherlands. In the Netherlands, one of the ways to index rent prices is to multiply the price with the Dutch Bureau of Statistics' (CBS, http://www.cbs.nl/) Consumer Price Index (CPI). The CPI is a float number larger than 1.0 that indicates the multiplication factor with which the old rent is to be multiplied. A Web service was set up at https://cpi-nl.heroku.com/ that serves these CPI numbers.

restarts.rb implements a new method Kernel#raise_condition which is similar to Kernel#raise for throwing exceptions, with the added feature of adding "restarts" next to the place where the exception is thrown so that they can be invoked from the exception handler somewhere higher up in the stack.

A very simple REST client.

This gem circumvents the "dynamic module include" (aka "double inclusion") problem, which is the fact that M.module_eval { include N } does not make the methods of module N available to modules and classes which had included module M beforehand, only to the ones that include it thereafter. This behaviour hurts the least surprise principle, specially because if K is a class, then K.class_eval { include M } *does* make all methods of M available to all classes which had previously inherited it.

[](http://travis-ci.org/estately/rets) A pure-ruby library for fetching data from [RETS] servers. If you're looking for a slick CLI interface check out [retscli](https://github.com/summera/retscli), which is an awesome tool for exploring metadata or learning about RETS. [RETS]: http://www.rets.org

return_bang implements non-local exits for methods. As a bonus, you also get exception handling that ignores standard Ruby's inflexible begin; rescue; ensure; end syntax. Use return_bang to exit back to a processing loop from deeply nested code, or just to confound your enemies *and* your friends! What could possibly go wrong?

== DESCRIPTION: The RightScale AWS gems have been designed to provide a robust, fast, and secure interface to Amazon EC2, EBS, S3, SQS, SDB, and CloudFront. These gems have been used in production by RightScale since late 2006 and are being maintained to track enhancements made by Amazon. The RightScale AWS gems comprise: - RightAws::Ec2 -- interface to Amazon EC2 (Elastic Compute Cloud), VPC (Virtual Private Cloud) and the associated EBS (Elastic Block Store) - RightAws::S3 and RightAws::S3Interface -- interface to Amazon S3 (Simple Storage Service) - RightAws::Sqs and RightAws::SqsInterface -- interface to first-generation Amazon SQS (Simple Queue Service) - RightAws::SqsGen2 and RightAws::SqsGen2Interface -- interface to second-generation Amazon SQS (Simple Queue Service) - RightAws::SdbInterface and RightAws::ActiveSdb -- interface to Amazon SDB (SimpleDB) - RightAws::AcfInterface -- interface to Amazon CloudFront, a content distribution service - RightAws::AsInterface -- interface to Amazon Auto Scaling - RightAws::AcwInterface -- interface to Amazon Cloud Watch - RightAws::ElbInterface -- interface to Amazon Elastic Load Balancer - RightAws::RdsInterface -- interface to Amazon RDS instances == FEATURES:

ImageScience is a clean and happy Ruby library that generates thumbnails -- and kicks the living crap out of RMagick. Oh, and it doesn't leak memory like a sieve. :) For more information including build steps, see http://seattlerb.rubyforge.org/

ReverseGeocoder Gem

reverse_require requires specific files from the gems which depend on a certain RubyGem and contain the specified path. Using reverse_require one can allow others to easily extend the functionality of a RubyGem. Simply add reverse_require into the code of your RubyGem: reverse_require 'my_gem', 'some/path' Then other gems which depend upon +my_gem+ merely have to provide <tt>some/path</tt> within their <tt>lib/</tt> directory, and reverse_require will load them all at run-time. This ability makes designing plug-in systems for a RubyGem trivial.
