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

This package provides a selection of regular expression subroutines including is_regexp, regexp_seen_evals, regexp_is_foreign, regexp_is_anchored, serialize_regexp, and deserialize_regexp.

Mozilla::CA provides a copy of Mozilla's bundle of Certificate Authority certificates in a form that can be consumed by modules and libraries based on OpenSSL.

This module simply interpolates option file hints in @ARGV by the contents of the pointed files. This enables option reading from files instead of or additional to the usual reading from the command line.

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

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.

Pod::Parser is a base class for creating POD filters and translators. It handles most of the effort involved with parsing the POD sections from an input stream, leaving subclasses free to be concerned only with performing the actual translation of text.

NOTE: This module is considered legacy. New projects should prefer Pod::Simple instead.

This module may be used to convert from under_score text to CamelCase and back again.

POSIX::strftime::Compiler provides GNU C library compatible strftime(3). But this module is not affected by the system locale. This feature is useful when you want to write loggers, servers, and portable applications.

RFCs 2822 and 822 specify date formats to be used by email. This module parses and emits such dates.

List::SomeUtils provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.

All of the below functions are implementable in only a couple of lines of Perl code. Using the functions from this module however should give slightly better performance as everything is implemented in C. The pure-Perl implementation of these functions only serves as a fallback in case the C portions of this module couldn't be compiled on this machine.

Lingua::Translit can be used to convert text from one writing system to another, based on national or international transliteration tables. Where possible a reverse transliteration is supported.

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.

This module splits a set of data with IDs and arbitrary values into one test file per (key+value) for easy parallelisation.

This module provides various portable helper functions for module building modules.

The Eval::WithLexicals Perl library provides support for lexical scope evaluation. This package also includes the tinyrepl command, which can be used as a minimal Perl read-eval-print loop (REPL).

This package compiles yacc-like Look Ahead LR (LALR) grammars to generate Perl object oriented parser modules.

It's boring to deal with opening files for IO, converting strings to handle-like objects, and all that. With Mixin::Linewise::Readers and Mixin::Linewise::Writers, you can just write a method to handle handles, and methods for handling strings and file names are added for you.

This module converts Perl data structures to JSON and vice versa.

Collection of classes that wrap fundamental data types that exist in Perl. These classes and methods as they exist today are an attempt to mirror functionality provided by Moose's Native Traits. One important thing to note is all classes currently do no validation on constructor input.

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 an interface to layout and image generation of directed and undirected graphs in a variety of formats (PostScript, PNG, etc.) using the dot, neato, twopi, circo, and fdp programs from the Graphviz project. This package is deprecated in favour of GraphViz2.

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.

Simply loading this module makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it calls Moose->throw_error().
