Storable brings persistence to your Perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time.

These self-contained Perl modules provide cryptography based on the LibTomCrypt library.

Modern::Perl provides a simple way to enable multiple, by now, standard libraries in a Perl program.

Switch is a Perl module which implements a generalized case mechanism. The module augments the standard Perl syntax with two new statements: switch and case.

This package eases the writing of command line utilities, accepting commands and subcommands and so on. These commands can form a tree, which is mirrored in the package structure. On invocation, each command along the path through the tree (starting from the top-level command through to the most specific one) is instantiated.

Sys::SigAction is a Perl extension for Consistent Signal Handling.

PerlIO::utf8_strict provides a fast and correct UTF-8 PerlIO layer. Unlike Perl's default :utf8 layer it checks the input for correctness.

The package provides Perl bindings to OpenGL, GLU and FreeGLUT.

Scalar::String is about the string part of plain Perl scalars. A scalar has a string value, which is notionally a sequence of Unicode codepoints but may be internally encoded in either ISO-8859-1 or UTF-8. In places, more so in older versions of Perl, the internal encoding shows through. To fully understand Perl strings it is necessary to understand these implementation details. This module provides functions to classify a string by encoding and to encode a string in a desired way. The module is implemented in XS, with a pure Perl backup version for systems that cannot handle XS.

Adds support on top of MooseX::Traits for class precedence search for traits and some extra attributes.

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.

DateTime::Format::ISO8601 is a DateTime extension that parses almost all ISO8601 date and time formats.

This module provides a simple syntax for creating object classes.

Clipboard provides functionality to copy and paste with any OS.

Given a list of scalars or reference variables, Data::Dumper writes out their contents in Perl syntax. The references can also be objects. The content of each variable is output in a single Perl statement. It handles self-referential structures correctly.

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 module offers a minimalist class construction kit. It uses no non-core modules for any recent Perl.

This is a library for generating letters, building HTML pages, or filling in templates generally. A template is a piece of text that has little Perl programs embedded in it here and there. When you fill in a template, you evaluate the little programs and replace them with their values.

This package provides a way to have readable configuration files outside your Perl script. Configurations can be imported, sections can be grouped, and settings can be accessed from a tied hash.

Given a list of Perl modules/filenames, this module makes require and use statements fail (no matter whether the specified files/modules are installed or not).

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

Mouse is a Moose compatible object system that implements a subset of the functionality for reduced startup time.

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.

This package provides tools for inspecting subroutines in Perl.
