This module allows you to wrap OP check callbacks.

The Digest::SHA Perl module implements the hash functions of the SHA family. It also provides the shasum binary.

This module implements the Perl foreign function interface XS for C++; it is a thin layer over plain XS.

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

This module makes some new features of the Perl 5.14.0 C API available to XS modules running on older versions of Perl. The features are centred around the function cv_set_call_checker, which allows XS code to attach a magical annotation to a Perl subroutine, resulting in resolvable calls to that subroutine being mutated at compile time by arbitrary C code. This module makes cv_set_call_checker and several supporting functions available.

Text::ParseWords module is used to parse text into an array of tokens or array of arrays.

Term::ANSIColor provides constants and simple functions for setting ANSI text attributes, most notably colors. It can be used to set the current text attributes or to apply a set of attributes to a string and reset the current text attributes at the end of that string. Eight-color, sixteen-color, 256-color, and true color (24-bit color) escape sequences are all supported.

This module provides lexicon-handling modules to read from other localization formats, such as Gettext, Msgcat, and so on.

Exporter implements an import method which allows a module to export functions and variables to its users' namespaces. Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimised for the common case.

Data::Float is about the native floating point numerical data type. A floating point number is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native floating point type, classification functions and functions to manipulate floating point values at a low level.

This module implements the Rijndael cipher which has been selected as the Advanced Encryption Standard. The keysize for Rijndael is 32 bytes. The blocksize is 16 bytes (128 bits). The supported encryption modes are:

• MODE_CBC---Cipher Block Chaining

• MODE_CFB---Cipher feedback

• MODE_CTR---Counter mode

• MODE_ECB---Electronic cookbook mode

• MODE_OFB---Output feedback

This Perl module provides various functions to quickly sort arrays by one or multiple calculated keys.

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.

Pod::Simple is a Perl library for parsing text in the Pod (plain old documentation) markup language that is typically used for writing documentation for Perl and for Perl modules.

This package provides Digest::SHA3, an implementation of the NIST SHA-3 message digest algorithm for use by Perl programs.

Sub::Exporter provides a sophisticated alternative to Exporter.pm for custom-built routines.

DateTime is a class for the representation of date/time combinations. It represents the Gregorian calendar, extended backwards in time before its creation (in 1582).

YAML::XS is a Perl XS binding to libyaml which offers Perl the best YAML support to date.

This is a Moose role which provides an alternate constructor for creating objects using parameters passed in from the command line.

Ref::Util::XS is the XS implementation of Ref::Util, which provides several functions to help identify references in a more convenient way than the usual approach of examining the return value of ref.

Guard implements so-called guards. A guard is something (usually an object) that "guards" a resource, ensuring that it is cleaned up when expected.

Specifically, this module supports two different types of guards: guard objects, which execute a given code block when destroyed, and scoped guards, which are tied to the scope exit.

This module provides a Log::Any adapter to send log messages to screen, with colors and some other features.

Test::Run is an improved test harness, originally based on Test::Harness version 2.xx by Michael G. Schwern, Andy Lester and others.

The top-level "Test::Run" by itself does not do much. You should refer to Task::Test::Run::AllPlugins for more detailed instructions.

Config::Any provides a facility for Perl applications and libraries to load configuration data from multiple different file formats. It supports XML, YAML, JSON, Apache-style configuration, and Perl code.
