Probe::Perl provides methods for obtaining information about the currently running perl interpreter. It originally began life as code in the Module::Build project, but has been externalized here for general use.

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.

This module provides a mechanism for determining if the pod for a given module is comprehensive.

This Perl library provides a function which tells whether a specific time falls within a specified time period. Its syntax for specifying time periods allows you to test for conditions like "Monday to Friday, 9am till 5pm" and "on the second Tuesday of the month" and "between 4pm and 4:15pm" and "in the first half of each minute" and "in January of 1998".

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.

A chained accessor is one that always returns the object when called with parameters (to set), and the value of the field when called with no arguments. This module subclasses Class::Accessor in order to provide the same mk_accessors interface.

This module generalises the mechanism of the wantarray function, allowing a function to determine in some detail how its return value is going to be immediately used.

This library allows communication with a smart card using PC/SC from a Perl script.

Moo is an extremely light-weight Object Orientation system. It allows one to concisely define objects and roles with a convenient syntax that avoids the details of Perl's object system. Moo contains a subset of Moose and is optimised for rapid startup.

This module provides a small, fast utility for working with file paths.

This module provides some extra datatypes that are used by common serialisation formats such as JSON or CBOR.

Exception::Class allows you to declare exception hierarchies in your modules in a "Java-esque" manner.

PadWalker is a module which allows you to inspect (and even change) lexical variables in any subroutine which called you. It will only show those variables which are in scope at the point of the call. PadWalker is particularly useful for debugging.

DateTime::Format::Natural takes a string with a human readable date/time and creates a machine readable one by applying natural parsing logic.

Routines to manipulate defhash, a convention to define things more precisely and uniformly using a hash, in Perl.

Exporter::Tiny supports many of Sub::Exporter's external-facing features including renaming imported functions with the `-as`, `-prefix` and `-suffix` options; explicit destinations with the `into` option; and alternative installers with the `installer` option. But it's written in only about 40% as many lines of code and with zero non-core dependencies.

This package provides an ASCII mapping for the eucJP encoding.

Similar to List::MoreUtils, Hash::MoreUtils contains trivial but commonly-used functionality for hashes. The primary focus for the moment is providing a common API - speeding up by XS is far away at the moment.

When an undefined variable is dereferenced, it gets silently upgraded to an array or hash reference (depending of the type of the dereferencing). This behaviour is called autovivification and usually does what you mean but it may be unnatural or surprising because your variables get populated behind your back. This is especially true when several levels of dereferencing are involved, in which case all levels are vivified up to the last, or when it happens in intuitively read-only constructs like exists. The pragma provided by this package lets you disable autovivification for some constructs and optionally throws a warning or an error when it would have happened.

This is a unified interface to retrieve terminal size. It loads one module of a list of known alternatives, each implementing some way to get the desired terminal information. This loaded module will actually do the job on behalf of Term::Size::Any.

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

This module understands the ICal date/time and duration formats, as defined in RFC 2445. It can be used to parse these formats in order to create the appropriate objects.

This module makes some new features of the Perl 5.14.0 C API available to XS modules running on older versions of Perl. The features are centred around the function cv_set_call_checker, which allows XS code to attach a magical annotation to a Perl subroutine, resulting in resolvable calls to that subroutine being mutated at compile time by arbitrary C code. This module makes cv_set_call_checker and several supporting functions available.

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.
