This module exports methods useful for factory classes.

This is Graph, a Perl module for dealing with graphs, the abstract data structures.

Params::Util provides a basic set of importable functions that makes checking parameters easier.

This module provides tools to deal with International Standard Book Numbers, including ISBN-10 and ISBN-13.

ExtUtils::PkgConfig is a very simplistic interface to the pkg-config utility, intended for use in the Makefile.PL of perl extensions which bind libraries that pkg-config knows. It is really just boilerplate code that you would have written yourself.

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

This module tries to find middle ground between one at a time and all at once processing of data sets. The purpose of this module is to avoid the overhead of implementing an iterative api when this isn't necessary, without breaking forward compatibility in case that becomes necessary later on.

Class::Method::Modifiers provides three modifiers: before, around, and after. before and after are run just before and after the method they modify, but can not really affect that original method. around is run in place of the original method, with a hook to easily call that original method.

DateTime is a class for the representation of date/time combinations. It represents the Gregorian calendar, extended backwards in time before its creation (in 1582).

Parallel::ForkManager is intended for use in operations that can be done in parallel where the number of processes to be forked off should be limited.

Devel::GlobalDestruction provides a function returning the equivalent of "${^GLOBAL_PHASE} eq 'DESTRUCT'" for older perls.

shell-quote lets you pass arbitrary strings through the shell so that they won't be changed.

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.

This module disables bareword filehandles.

Throwable is a role for classes that are meant to be thrown as exceptions to standard program flow.

Set::Infinite is a set theory module for infinite sets.

This library provides a set of Path::Tiny types and coercions for Specio. These types can be used with Moose, Moo, Params::ValidationCompiler, and other modules.

The Params::Validate module allows you to validate method or function call parameters to an arbitrary level of specificity.

The functions exported by this module allow you to open URLs in the user's browser. A set of known commands per OS-name is tested for presence, and the first one found is executed. With an optional parameter, all known commands are checked.

This package provides a package to change terminal modes and perform non-blocking reads.

Devel::OverloadInfo returns information about overloaded operators for a given class (or object), including where in the inheritance hierarchy the overloads are declared and where the code implementing it is.

This module runs code after a subroutine call, preserving the context the subroutine would have seen if it were the last statement in the caller.

XML::Writer is a simple Perl module for writing XML documents: it takes care of constructing markup and escaping data correctly. By default, it also performs a significant amount of well-formedness checking on the output to make certain (for example) that start and end tags match, that there is exactly one document element, and that there are not duplicate attribute names.

This module provide functions that takes a list of values as their argument and produces a string as its result. The string contains Perl code that, when "eval"ed, produces a deep copy of the original arguments.
