This module implements a subset of the YAML specification for use in reading and writing CPAN metadata files like META.yml and MYMETA.yml.

This module provides a convenient way to perform cleanup or other forms of resource management at the end of a scope. It is particularly useful when dealing with exceptions: the Scope::Guard constructor takes a reference to a subroutine that is guaranteed to be called even if the thread of execution is aborted prematurely. This effectively allows lexically-scoped "promises" to be made that are automatically honoured by perl's garbage collector.

This module in a fully object-oriented implementation of a simple n-ary tree.

This module allows errors from a clan (or family) of modules to appear to originate from the caller of the clan. This is necessary in cases where the clan modules are not classes derived from each other, and thus the Carp.pm module doesn't help.

MooseX::Role::WithOverloading allows you to write a Moose::Role which defines overloaded operators and allows those overload methods to be composed into the classes/roles/instances it's compiled to, where plain Moose::Roles would lose the overloading.

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

This module provides functions for fast and correct file slurping and spewing. All functions are optionally exported.

This module provides convenience methods that let you easily create DateTime::Set objects for RFC 2445 style recurrences.

This module provides a class to monitor a directory for changes made to any file.

The namespace::autoclean pragma will remove all imported symbols at the end of the current package's compile cycle. Functions called in the package itself will still be bound by their name, but they won't show up as methods on your class or instances. It is very similar to namespace::clean, except it will clean all imported functions, no matter if you imported them before or after you used the pragma. It will also not touch anything that looks like a method.

Unicode::LineBreak implements the line breaking algorithm described in Unicode Standard Annex #14. The East_Asian_Width property defined by Annex #11 is used to determine breaking positions.

Date::Calc::XS is an XS wrapper and C library plug-in for Date::Calc.

The Cache modules are designed to assist a developer in persisting data for a specified period of time. Often these modules are used in web applications to store data locally to save repeated and redundant expensive calls to remote machines or databases. People have also been known to use Cache::Cache for its straightforward interface in sharing data between runs of an application or invocations of a CGI-style script or simply as an easy to use abstraction of the file system or shared memory.

This is a backend for Package::Stash, which provides the functionality in a way that's less buggy and much faster. It will be used by default if it's installed, and should be preferred in all environments with a compiler.

When subclassing a class, you may occasionally want to dispatch control to the superclass---at least conditionally and temporarily. This module provides nicer equivalents to the native Perl syntax for calling superclasses, along with a universal super method to determine a class' own superclass, and better support for run-time mix-ins and roles.

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

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.

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.

YAML::Syck provides a Perl interface to the libsyck data serialization library. It exports the Dump and Load functions for converting Perl data structures to YAML strings, and the other way around.

This package provides an ASCII mapping for the eucJP encoding.

This module understands the W3CDTF date/time format, an ISO 8601 profile, defined at https://www.w3.org/TR/NOTE-datetime. This format is the native date format of RSS 1.0. It can be used to parse these formats in order to create the appropriate objects.

This module exports a single function: ttie. It ties a variable to a type constraint, ensuring that whatever values stored in the variable will conform to the type constraint. If the type constraint has coercions, these will be used if necessary to ensure values assigned to the variable conform.

This package provides encodings for JIS X 0212, which is also known as JIS 2000.

Internationalized Domain Names (IDNs) use characters drawn from a large repertoire (Unicode), but IDNA allows the non-ASCII characters to be represented using only the ASCII characters already allowed in so-called host names today (letter-digit-hyphen, /[A-Z0-9-]/i).

Use this module if you just want to convert domain names (or email addresses), using whatever IDNA standard is the best choice at the moment.
