Mail::RFC822::Address validates email addresses against the grammar described in RFC 822 using regular expressions.

Chaolin Zhang's Perl Library (czplib) contains assorted functions and data structures for processing and analysing genomic and bioinformatics data.

Crypt::RandPasswd provides three functions that can be used to generate random passwords, constructed from words, letters, or characters. This code is a Perl implementation of the Automated Password Generator standard, like the program described in "A Random Word Generator For Pronounceable Passwords". This code is a re-engineering of the program contained in Appendix A of FIPS Publication 181, "Standard for Automated Password Generator".

This package provides tools for inspecting subroutines in Perl.

Hash::FieldHash provides the field hash mechanism which supports the inside-out technique. It is an alternative to Hash::Util::FieldHash with a simpler interface, higher performance, and relic support.

This toolkit primarily provides modules for performing both traditional and object-oriented i/o) on things *other* than normal filehandles; in particular, IO::Scalar, IO::ScalarArray, and IO::Lines.

This module compares arbitrary data structures to see if they are copies of each other.

Exporter::Tiny supports many of Sub::Exporter's external-facing features including renaming imported functions with the `-as`, `-prefix` and `-suffix` options; explicit destinations with the `into` option; and alternative installers with the `installer` option. But it's written in only about 40% as many lines of code and with zero non-core dependencies.

This module exports all of the functions that either List::Util or List::MoreUtils defines, with preference to List::Util.

This is a meta-package that installs the CPAN dependencies of the Freecell Solver test suite.

The File::LibMagic module is a simple perl interface to libmagic from the file package.

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.

Data::Perl is a container class for the following classes:

• Data::Perl::Collection::Hash

• Data::Perl::Collection::Array

• Data::Perl::String

• Data::Perl::Number

• Data::Perl::Counter

• Data::Perl::Bool

• Data::Perl::Code

This Perl module provides a central location for modules to report monitoring metrics, such as counters of the number of times interesting events have happened, and programs to collect up and send those metrics to monitoring services.

Parse::RecDescent can incrementally generate top-down recursive-descent text parsers from simple yacc-like grammar specifications.

This module packages several Moose::Util::TypeConstraints with coercions, designed to work with the DateTime suite of objects.

This module provides various type-testing functions. These are intended for functions that care what type of data they are operating on. There are two flavours of function. Functions of the first flavour provide type classification only. Functions of the second flavour also check that an argument is of an expected type. The type enforcement functions handle only the simplest requirements for arguments of the types handled by the classification functions. Enforcement of more complex types may be built using the classification functions, or it may be more convenient to use a module designed for the more complex job, such as Params::Validate

This is a unified interface to retrieve terminal size. It loads one module of a list of known alternatives, each implementing some way to get the desired terminal information. This loaded module will actually do the job on behalf of Term::Size::Any.

This module provides bare bones try/catch/finally statements that are designed to minimize common mistakes with eval blocks, and nothing else.

Text::Unidecode provides a function, unidecode(...) that takes Unicode data and tries to represent it in US-ASCII characters (i.e., the universally displayable characters between 0x00 and 0x7F). The representation is almost always an attempt at transliteration-- i.e., conveying, in Roman letters, the pronunciation expressed by the text in some other writing system.

This module understands the formats used by SQLite for its date, datetime and time functions. It can be used to parse these formats in order to create DateTime objects, and it can take a DateTime object and produce a timestring accepted by SQLite.

Clipboard provides functionality to copy and paste with any OS.

This module provides three utility subroutines that make it easier to develop interactive applications: is_interactive(), interactive(), and busy().

IPC::Cmd allows for the searching and execution of any binary on your system. It adheres to verbosity settings and is able to run interactively. It also has an option to capture output/error buffers.
