CHI provides a unified caching API, designed to assist a developer in persisting data for a specified period of time.

The CHI interface is implemented by driver classes that support fetching, storing and clearing of data. Driver classes exist or will exist for the gamut of storage backends available to Perl, such as memory, plain files, memory mapped files, memcached, and DBI.

SDL Perl is a package of Perl modules that provide both functional and object oriented interfaces to the Simple DirectMedia Layer for Perl5. This package takes some liberties with the SDL API, and attempts to adhere to the spirit of both the SDL and Perl.

This package provides basic statistics functions like median(), mean(), variance() and stddev().

This Clone::Choose module checks several different modules which provide a clone() function and selects an appropriate one.

This module is a data dumper optimized for logging of arbitrary parameters.

Module::Build is a system for building, testing, and installing Perl modules; it used to be part of Perl itself until version 5.22, which dropped it. It is meant to be an alternative to ExtUtils::MakeMaker. Developers may alter the behavior of the module through subclassing in a much more straightforward way than with MakeMaker. It also does not require a make on your system---most of the Module::Build code is pure-Perl.

The Term::Animation Perl module provides a framework to produce sprite animations using ASCII art. Each ASCII 'sprite' is given one or more frames, and placed into the animation as an 'animation entity'. An animation entity can have a callback routine that controls the position and frame of the entity. The module can also do collision detection between entities.

Authen-Passphrase is the base class for a system of objects that encapsulate passphrases. An object of this type is a passphrase recogniser; its job is to recognise whether an offered passphrase is the right one. For security such passphrase recognisers usually do not themselves know the passphrase they are looking for; they can merely recognise it when they see it. There are many schemes in use to achieve this effect and the intent of this class is to provide a consistent interface to them all. In addition to the base class, this module also contains implementations of several specific passphrase schemes.

File::Grep provides similar functionality as perl's builtin grep, map, and foreach commands, but iterating over a passed filelist instead of arrays. While trivial, this module can provide a quick dropin when such functionality is needed.

These self-contained Perl modules provide cryptography based on the LibTomCrypt library.

This is pragma to change Perl 5's standard method resolution order from depth-first left-to-right (a.k.a - pre-order) to the more sophisticated C3 method resolution order.

This module does not provide any methods. Simply loading it changes the default naming policy for the loading class so that accessors are separated into get and set methods. The get methods have the same name as the accessor, while set methods are prefixed with "_set_".

Stream::Buffered is a buffer class to store arbitrary length of byte strings and then get a seekable filehandle once everything is buffered. It uses PerlIO and/or temporary file to save the buffer depending on the length of the size.

This module attempts to work around people calling UNIVERSAL::can() as a function, which it is not.

This module provides routines for parsing date string into time values and formatting dates into ASCII strings.

When an undefined variable is dereferenced, it gets silently upgraded to an array or hash reference (depending of the type of the dereferencing). This behaviour is called autovivification and usually does what you mean but it may be unnatural or surprising because your variables get populated behind your back. This is especially true when several levels of dereferencing are involved, in which case all levels are vivified up to the last, or when it happens in intuitively read-only constructs like exists. The pragma provided by this package lets you disable autovivification for some constructs and optionally throws a warning or an error when it would have happened.

This module provides functions for expressing durations in rounded or exact terms.

Class::XSAccessor implements fast read, write, and read/write accessors in XS. Additionally, it can provide predicates such as "has_foo()" for testing whether the attribute "foo" is defined in the object. It only works with objects that are implemented as ordinary hashes. Class::XSAccessor::Array implements the same interface for objects that use arrays for their internal representation.

XML::Writer is a simple Perl module for writing XML documents: it takes care of constructing markup and escaping data correctly. By default, it also performs a significant amount of well-formedness checking on the output to make certain (for example) that start and end tags match, that there is exactly one document element, and that there are not duplicate attribute names.

File::Find::Object is an object-oriented File::Find replacement in Perl.

Text::TabularDisplay simplifies displaying textual data in a table. The output is identical to the columnar display of query results in the mysql text monitor.

This package eases the writing of command line utilities, accepting commands and subcommands and so on. These commands can form a tree, which is mirrored in the package structure. On invocation, each command along the path through the tree (starting from the top-level command through to the most specific one) is instantiated.

List::Compare provides a module to perform comparative operations on two or more lists. Provided operations include intersections, unions, unique elements, complements and many more.

This package allows you to define different interpreters for different test scripts with Test::Run.
