This library is intended to provide a reducer library on collections for ruby like the clojure reducers

A multi-line search and replace utility that uses Ruby regular expressions for searching and allows back references to captured groups from the pattern to appear in the replacement text.

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).

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.

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?

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.

reverse-require allows one to require files that ends with a specified path from other RubyGems. For instance, if one wanted to require the file 'mylibrary/extensions.rb' from all RubyGems: require 'reverse_require' require_all 'mylibrary/extensions' # => true One can also require 'mylibrary/extensions.rb' only from RubyGems that depend on the currently loaded version of the mylibrary Gem: require_for 'mylibrary', 'mylibrary/extensions' # => true

Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among Nokogiri's many features is the ability to search documents via XPath or CSS3 selectors. XML is like violence - if it doesn’t solve your problems, you are not using enough of it.

rFeedFinder uses RSS autodiscovery, Atom autodiscovery, spidering, URL correction, and Web service queries -- whatever it takes -- to find the feed.
