Oniguruma is a BSDL Regular Expression library written for ruby-m17n, which implements all of Perl extensions, many of .NET extensions plus more. It provides multiple APIs for ease of use; GNU regex compatible API, POSIX regex compatible API and its own. This library is multilingualized by design and can have one encoding for each regex object. Currently supported character encodings are ASCII, UTF-8, EUC-JP and Shift_JIS. 4.x supports Ruby1.9.

OpenGrok is a fast source code search and cross reference engine. It helps you search, cross-reference and navigate your source tree. It can understand various program file formats and version control histories like Mercurial, Git, SCCS, RCS, CVS, Subversion, Teamware, ClearCase, Perforce and Bazaar. In other words it lets you grok (profoundly understand) the open source, hence the name OpenGrok. It is written in Java.

Mercurial is a fast, lightweight source control management system designed for efficient handling of very large distributed projects. Features include: * O(1) delta-compressed file storage and retrieval scheme * Complete cross-indexing of file and changesets for efficient exploration of project history * Robust SHA1-based integrity checking and append-only storage model * Decentralized development model with arbitrary merging between trees * High-speed HTTP-based network merge protocol * Easy-to-use command-line interface * Integrated stand-alone web interface * Small Python codebase * GPL license

Carp::Assert::More is a set of wrappers around the Carp::Assert functions to make the habit of writing assertions even easier. Everything in here is effectively syntactic sugar. There's no technical reason to use assert_isa( $foo, 'HTML::Lint' ); instead of assert( defined $foo ); assert( ref($foo) eq 'HTML::Lint' ); other than readability and simplicity of the code. My intent here is to make common assertions easy so that we as programmers have no excuse to not use them.

This module makes it easy to build classes using array based objects. It's main goal is to allow one to create less memory hungry programs, notably in memory-sensitive contexts such as mod_perl. This module is little more than a cute way of defining constant subs in your own package. Constant subs are very useful when dealing with array based objects because they allow one to access array slots by name instead of by index.

Date::Business provides the functionality to perform simple date manipulations quickly. Support for calendar date and business date math is provided. Business dates are weekdays only. Adding 1 to a weekend returns Monday, subtracting 1 returns Friday. The difference in business days between Friday and the following Monday (using the diffb function) is one business day. The number of business days between Friday and the following Monday (using the betweenb function) is zero.

The Perl 5 module Devel::Events::Objects provides an event generator and a handler for Devel::Events, that facilitate leak checking. There are two components of this module: Devel::Events::Generator::Objects, and Devel::Events::Handler::ObjectTracker. The first one uses some trickery to generate events for every object creation and destruction in code loaded after it was loaded. The second one will listen on these events, and track all currently living objects.

Perl's global destruction is a little tricky to deal with WRT finalizers because it's not ordered and objects can sometimes disappear. Writing defensive destructors is hard and annoying, and usually if global destruction is happenning you only need the destructors that free up non process local resources to actually execute. For these constructors you can avoid the mess by simply bailing out if global destruction is in effect.

This module provides an attribute wrapper around Getopt::Long. Instead of declaring the options in a hash with references to the variables and subroutines affected by the options, you can use the Getopt attribute on the variables and subroutines directly. As you can see from the Synopsis, the attribute takes an argument of the same format as you would give as the hash key for Getopt::Long. See the Getopt::Long manpage for details.
