Sub::Exporter is an incredibly powerful module, but with that power comes great responsibility, as well as some runtime penalties. This module is a "Sub::Exporter" wrapper that will let your users just use Exporter if all they are doing is picking exports, but use "Sub::Exporter" if your users try to use "Sub::Exporter"'s more advanced features, like renaming exports, if they try to use them.

Text::Patch combines source text with given diff (difference) data. Diff data is produced by Text::Diff module or by the standard diff utility.

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

List::SomeUtils::XS is a XS implementation for List::SomeUtils. There are no user-facing parts here. See List::SomeUtils for API details.

This package is an internationalization library for Perl that aims to be compatible with the Uniforum message translations system as implemented for example in GNU gettext.

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.

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

This package provides asynchronous file and directory I/O for Perl.

Sub::Install makes it easy to install subroutines into packages without the unsightly mess of C<no strict> or typeglobs lying about where just anyone can see them.

Crypt::CBC is a Perl-only implementation of the cryptographic Cipher Block Chaining (CBC) mode. In combination with a block cipher such as Crypt::Rijndael you can encrypt and decrypt messages of arbitrarily long length. The encrypted messages are compatible with the encryption format used by SSLeay.

File::HomeDir is a module for locating the directories that are owned by a user (typically your user) and to solve the various issues that arise trying to find them consistently across a wide variety of platforms.

Data::Uniqid provides three simple routines for generating unique ids. These ids are coded with a Base62 system to make them short and handy (e.g. to use it as part of a URL).

This pragma allows you to declare constants at compile-time. When a constant is used in an expression, Perl replaces it with its value at compile time, and may then optimize the expression further. In particular, any code in an if (CONSTANT) block will be optimized away if the constant is false.

This module tries to make it easy to build Perl extensions that use functions and typemaps provided by other perl extensions. This means that a perl extension is treated like a shared library that provides also a C and an XS interface besides the perl one.

This package provides basic statistics functions like median(), mean(), variance() and stddev().

Guard implements so-called guards. A guard is something (usually an object) that "guards" a resource, ensuring that it is cleaned up when expected.

Specifically, this module supports two different types of guards: guard objects, which execute a given code block when destroyed, and scoped guards, which are tied to the scope exit.

This module overrides CORE::GLOBAL::require with a code reference in a way that plays nice with any existing overloading and ensures the right calling package is in scope.

Template::Tiny is a reimplementation of a subset of the functionality from Template Toolkit in as few lines of code as possible.

It is intended for use in light-usage, low-memory, or low-cpu templating situations, where you may need to upgrade to the full feature set in the future, or if you want the retain the familiarity of TT-style templates.

Crypt::DES is an XS-based implementation of the DES cryptography algorithm. The module implements the Crypt::CBC interface which has blocksize, keysize, encrypt and decrypt functions.

Set::Object provides efficient sets, unordered collections of Perl objects without duplicates for scalars and references.

Pegex is an Acmeist parser framework. It allows you to easily create parsers that will work equivalently in lots of programming languages. The inspiration for Pegex comes from the parsing engine upon which the postmodern programming language Perl 6 is based on. Pegex brings this beauty to the other justmodern languages that have a normal regular expression engine available.

YAML::PP is a modular YAML processor. It aims to support YAML 1.2 and YAML 1.1.

This package provides asynchronous Berkeley DB Access.

This class provides a tie constructor that returns the object it was given as it's first argument. This way side effects of calling $object->TIEHASH are avoided.
