Data::Entropy provides modules relating to the generation and use of entropy. The Data::Entropy::Source class manages the entropy coming from a particular source. This class acts as a layer over a raw entropy source, which may be a normal I/O handle or a special-purpose class. The Data::Entropy::RawSource::* classes provide fundamental sources of entropy. The sources specially supported are an OS-supplied entropy collector, downloads from servers on the Internet, and cryptographic fake entropy. The Data::Entropy::Algorithms module contains a collection of fundamental algorithms that use entropy. There are random number generators and functions to shuffle arrays.

Ref::Util introduces several functions to help identify references in a smarter (and usually faster) way. The difference with conventional approach:

• No comparison against a string constant

• Supports blessed variables

• Supports tied variables and magic

• Ignores overloading

• Ignores subtle types

• Usually faster

This module allows code attributes of methods to be introspected using Moose meta method objects.

Config::Grammar is a module to parse configuration files. The configuration may consist of multiple-level sections with assignments and tabular data.

File::Find::Object::Rule is an alternative Perl interface to File::Find::Object.

This package provides a way to have readable configuration files outside your Perl script. Configurations can be imported, sections can be grouped, and settings can be accessed from a tied hash.

This is a minimalist Perl module for building simple classes with read-only accessors.

File::Next is a Perl CPAN module for finding files.

Shell::Command is a thin wrapper around ExtUtils::Command.

This subclass of Module::Build adds some tools and processes to make it easier to use for wrapping C++ using XS++ (ExtUtils::XSpp).

The fundamental task of the autoformat subroutine is to identify and rearrange independent paragraphs in a text. Paragraphs typically consist of a series of lines containing at least one non-whitespace character, followed by one or more lines containing only optional whitespace. This is a more liberal definition than many other formatters use: most require an empty line to terminate a paragraph. Paragraphs may also be denoted by bulleting, numbering, or quoting (see the following sections).

PPIx::Utils is a collection of utility functions for working with PPI documents. The functions are organized into submodules, and may be imported from the appropriate submodules or via this module.

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

This module allows you to manage a set of deprecations for one or more modules.

MIME::Charset provides information about character sets used for MIME messages on Internet.

This package is a plugin to tidyall allowing integration with the Test::Count module, to keep track of the number of tests in a test file.

Struct::Dumb creates record-like structure types, similar to the struct keyword in C, C++ or C#, or Record in Pascal. An invocation of this module will create a construction function which returns new object references with the given field values. These references all respond to lvalue methods that access or modify the values stored.

The Time::Warp module offers developers control over the measurement of time.

File::HomeDir is a module for locating the directories that are owned by a user (typically your user) and to solve the various issues that arise trying to find them consistently across a wide variety of platforms.

File::ShareDir::Install allows you to install read-only data files from a distribution. It is a companion module to File::ShareDir, which allows you to locate these files after installation.

Crypt::DES is an XS-based implementation of the DES cryptography algorithm. The module implements the Crypt::CBC interface which has blocksize, keysize, encrypt and decrypt functions.

This module generalises the mechanism of the wantarray function, allowing a function to determine in some detail how its return value is going to be immediately used.

This module is an alternative to String::Trim. Instead of a single trim function, this module provides several from which you can choose on, depending on your needs.

MIME::Base64 module provides functions to encode and decode strings into and from the base64 encoding specified in RFC 2045 - MIME (Multipurpose Internet Mail Extensions). The base64 encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. A 65-character subset ([A-Za-z0-9+/=]) of US-ASCII is used, enabling 6 bits to be represented per printable character.
