Create a command line tool with your Mo, Moo, Moose objects. You have an option keyword to replace the usual has to explicitly use your attribute on the command line. The option keyword takes additional parameters and uses Getopt::Long::Descriptive to generate a command line tool.

Bit::Vector is an efficient C library which allows you to handle bit vectors, sets (of integers), "big integer arithmetic" and boolean matrices, all of arbitrary sizes. The package also includes an object-oriented Perl module for accessing the C library from Perl, and optionally features overloaded operators for maximum ease of use. The C library can nevertheless be used stand-alone, without Perl.

The Digest::MD4 module allows you to use the RSA Data Security Inc.: MD4 Message Digest algorithm from within Perl programs. The algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. MD4 is described in RFC 1320.

This module exports a single hash (%RE) that stores or generates commonly needed regular expressions. Patterns currently provided include: balanced parentheses and brackets, delimited text (with escapes), integers and floating-point numbers in any base (up to 36), comments in 44 languages, offensive language, lists of any pattern, IPv4 addresses, URIs, and Zip codes.

The "mro" namespace provides several utilities for dealing with method resolution order and method caching in general in Perl 5.9.5 and higher. This module provides those interfaces for earlier versions of Perl (back to 5.6.0).

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

This Perl module allows you to split data into records by not only specifying what you wish to split the data on, but also by specifying an "unless" regular expression. If the text in question matches the "unless" regex, it will not be split there. This allows us to do things like split on newlines unless newlines are embedded in quotes.

This package provides an ASCII mapping for the eucJP encoding.

Sys::CPU is a module for counting the number of CPUs on a system, and determining their type and clock speed.

This module provides functions to encode and decode UTF-8 encoding form as specified by Unicode and ISO/IEC 10646:2011.

DateTime::Format::Builder creates DateTime parsers. Many string formats of dates and times are simple and just require a basic regular expression to extract the relevant information. Builder provides a simple way to do this without writing reams of structural code.

File::Find::Object is an object-oriented File::Find replacement in Perl.

Crypt::PasswdMD5 provides various crypt()-compatible interfaces to the MD5-based crypt() function found in various *nixes. It is based on the implementation found on FreeBSD 2.2.[56]-RELEASE.

This module provides a collection of named blocks that allow a return statement to return different values depending on the context in which it is called.

This module has 3 functions: one to copy files only, one to copy directories only, and one to do either depending on the argument's type.

CHI provides a unified caching API, designed to assist a developer in persisting data for a specified period of time.

The CHI interface is implemented by driver classes that support fetching, storing and clearing of data. Driver classes exist or will exist for the gamut of storage backends available to Perl, such as memory, plain files, memory mapped files, memcached, and DBI.

File::Find::Rule is a friendlier interface to File::Find. It allows you to build rules which specify the desired files and directories.

This package provides various utility functions. When used without argument, this module provides four universally accessible attributes of general interest as follows:

• Abstract

• Alias

• Memoize

• Method

• SigHandler

Similar to List::MoreUtils, Hash::MoreUtils contains trivial but commonly-used functionality for hashes. The primary focus for the moment is providing a common API - speeding up by XS is far away at the moment.

Sub::Quote provides an efficient generation of subroutines via string eval.

This module solves the problem of having to continually write accessor methods for your objects that perform standard tasks.

"require EXPR" only accepts Class/Name.pm style module names, not Class::Name. For that, this module provides "load_class 'Class::Name'".

Devel::Caller provides meatier version of caller.

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.
