This module provides common interface to HMAC functionality. HMAC is a kind of "Message Authentication Code" (MAC) algorithm whose standard is documented in RFC2104. Namely, a MAC provides a way to check the integrity of information transmitted over or stored in an unreliable medium, based on a secret key. Originally written by Daiki Ueno.

RubyPython is a bridge between the Ruby and Python interpreters. It embeds a running Python interpreter in the Ruby application's process using FFI and provides a means for wrapping, converting, and calling Python objects and methods. RubyPython uses FFI to marshal the data between the Ruby and Python VMs and make Python calls. You can: * Inherit from Python classes. * Configure callbacks from Python. * Run Python generators (on Ruby 1.9.2 or later).

A Rubygems packaging tool that provides Rake tasks for documentation, extension compiling, testing, and deployment.

Transaction::Simple provides a generic way to add active transaction support to objects. The transaction methods added by this module will work with most objects, excluding those that cannot be Marshal-ed (bindings, procedure objects, IO instances, or singleton objects). The transactions supported by Transaction::Simple are not associated with any sort of data store. They are "live" transactions occurring in memory on the object itself. This is to allow "test" changes to be made to an object before making the changes permanent. Transaction::Simple can handle an "infinite" number of transaction levels (limited only by memory). If I open two transactions, commit the second, but abort the first, the object will revert to the original version. Transaction::Simple supports "named" transactions, so that multiple levels of transactions can be committed, aborted, or rewound by referring to the appropriate name of the transaction. Names may be any object except nil. Transaction groups are also supported. A transaction group is an object wrapper that manages a group of objects as if they were a single object for the purpose of transaction management. All transactions for this group of objects should be performed against the transaction group object, not against individual objects in the group. Version 1.4.0 of Transaction::Simple adds a new post-rewind hook so that complex graph objects of the type in tests/tc_broken_graph.rb can correct themselves. Version 1.4.0.1 just fixes a simple bug with #transaction method handling during the deprecation warning. Version 1.4.0.2 is a small update for people who use Transaction::Simple in bundler (adding lib/transaction-simple.rb) and other scenarios where having Hoe as a runtime dependency (a bug fixed in Hoe several years ago, but not visible in Transaction::Simple because it has not needed a re-release). All of the files internally have also been marked as UTF-8, ensuring full Ruby 1.9 compatibility.

The Lorax is a full diff and patch library for XML/HTML documents, based on Nokogiri. It can tell you whether two XML/HTML documents are identical, or if they're not, tell you what's different. In trivial cases, it can even apply the patch. It's based loosely on Gregory Cobena's master's thesis paper, which generates deltas in less than O(n * log n) time, accepting some tradeoffs in the size of the delta set. You can find his paper at http://gregory.cobena.free.fr/www/Publications/thesis.html. "I am the Lorax, I speak for the trees."

Erector is a Builder-like view framework, inspired by Markaby but overcoming some of its flaws. In Erector all views are objects, not template files, which allows the full power of object-oriented programming (inheritance, modular decomposition, encapsulation) in views.
