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

File::Zglob provides a traditional Unix glob functionality; it returns a list of file names that match the given pattern. For instance, it supports the **/*.pm form.

Role::Tiny is a minimalist role composition tool.

This module facilitates using Moose or Mouse modules without changing the code. By default, Mouse will be provided to libraries, unless Moose is already loaded, or explicitly requested by the end-user. End users can force the decision of which backend to use by setting the environment variable ANY_MOOSE to be Moose or Mouse.

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.

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.

This module provides tools to deal with International Standard Serial Numbers.

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".

Term::Encoding is a simple module to detect the encoding of the current terminal expects in various ways.

The Regexp::Grammars module adds a small number of new regex constructs that can be used within Perl 5.10 patterns to implement complete recursive-descent parsing. It allows you to go beyond matching complex, nested and recursive structures, and allows you to parse and extract hierarchical data from it.

Statistics::Distributions calculates percentage points (5 significant digits) of the u (standard normal) distribution, the student's t distribution, the chi-square distribution and the F distribution. It can also calculate the upper probability (5 significant digits) of the u (standard normal), the chi-square, the t and the F distribution.

This module, ReadKey, provides ioctl control for terminals so the input modes can be changed (thus allowing reads of a single character at a time), and also provides non-blocking reads of stdin, as well as several other terminal related features, including retrieval/modification of the screen size, and retrieval/modification of the control characters.

This module allows you to call isa, can, does, and DOES safely on things that may not be objects.

The mix_class function provided by this module dynamically generates anonymous classes with specified inheritance. This is useful where an incomplete class requires use of a mixin in order to become instantiable.

Exporter::Lite is an alternative to Exporter, intended to provide a lightweight subset of the most commonly-used functionality. It supports import(), @EXPORT and @EXPORT_OK and not a whole lot else.

This module implement a UDP client for the statsd statistics collector daemon in use at Etsy.com.

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

Moo is an extremely light-weight Object Orientation system. It allows one to concisely define objects and roles with a convenient syntax that avoids the details of Perl's object system. Moo contains a subset of Moose and is optimised for rapid startup.

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.

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

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

Data::Dump::Streamer provides ways to accurately serialize a data structure as Perl code.

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