Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.

This package provides encodings for JIS X 0212, which is also known as JIS 2000.

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.

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.

This module makes the functionality of the perltidy command available to Perl scripts. Any or all of the input parameters may be omitted, in which case the @ARGV array will be used to provide input parameters as described in the perltidy(1) man page.

Collection of classes that wrap fundamental data types that exist in Perl. These classes and methods as they exist today are an attempt to mirror functionality provided by Moose's Native Traits. One important thing to note is all classes currently do no validation on constructor input.

Given a list of Perl modules/filenames, this module makes require and use statements fail (no matter whether the specified files/modules are installed or not).

The Inline::C module allows you to write Perl subroutines in C. Since version 0.30 the Inline module supports multiple programming languages and each language has its own support module. This document describes how to use Inline with the C programming language. It also goes a bit into Perl C internals.

Text::Diff provides a basic set of services akin to the GNU diff utility. It is not anywhere near as feature complete as GNU diff, but it is better integrated with Perl and available on all platforms. It is often faster than shelling out to a system's diff executable for small files, and generally slower on larger files.

This package allows you to stop processing the entire test suite after the first failure, instead of going all the way through it.

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 module allows you to specify conflicting versions of modules separately and deal with them after the module is done installing.

This module creates a customized, highly efficient parameter checking subroutine. It can handle named or positional parameters, and can return the parameters as key/value pairs or a list of values. In addition to type checks, it also supports parameter defaults, optional parameters, and extra "slurpy" parameters.

Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.

DateTime::Format::ISO8601 is a DateTime extension that parses almost all ISO8601 date and time formats.

Lingua::Translit can be used to convert text from one writing system to another, based on national or international transliteration tables. Where possible a reverse transliteration is supported.

A CPAN::Meta::Requirements object models a set of version constraints like those specified in the META.yml or META.json files in CPAN distributions, and as defined by CPAN::Meta::Spec. It can be built up by adding more and more constraints, and will reduce them to the simplest representation.

This module applies roles to make a subclass instead of manually setting up a subclass.

Lexical::Persistence introduces persistent lexical variable values for arbitrary calls.

Text::Haml implements Haml http://haml.info/docs/yardoc/file.REFERENCE.html specification.

Class::ErrorHandler provides an error-handling mechanism that is generic enough to be used as the base class for a variety of OO classes. Subclasses inherit its two error-handling methods, error and errstr, to communicate error messages back to the calling program.

The Digest::HMAC module follows the common Digest:: interface for the RFC 2104 HMAC mechanism.

Parallel::ForkManager is intended for use in operations that can be done in parallel where the number of processes to be forked off should be limited.

The Readonly module is an effective way to create non-modifiable variables. However, it's relatively slow.

The reason it's slow is that is implements the read-only-ness of variables via tied objects. This mechanism is inherently slow. Perl simply has to do a lot of work under the hood to make tied variables work.

This module corrects the speed problem, at least with respect to scalar variables. When Readonly::XS is installed, Readonly uses it to access the internals of scalar variables. Instead of creating a scalar variable object and tying it, Readonly simply flips the SvREADONLY bit in the scalar's FLAGS structure.
