This package allows you to analyze tests from the command line using Test::Run.

Authen-Passphrase is the base class for a system of objects that encapsulate passphrases. An object of this type is a passphrase recogniser; its job is to recognise whether an offered passphrase is the right one. For security such passphrase recognisers usually do not themselves know the passphrase they are looking for; they can merely recognise it when they see it. There are many schemes in use to achieve this effect and the intent of this class is to provide a consistent interface to them all. In addition to the base class, this module also contains implementations of several specific passphrase schemes.

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.

The Digest::MD4 module allows you to use the RSA Data Security Inc.: MD4 Message Digest algorithm from within Perl programs. The algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. MD4 is described in RFC 1320.

This package provides a way to sort revision-like numbers.

Struct::Dumb creates record-like structure types, similar to the struct keyword in C, C++ or C#, or Record in Pascal. An invocation of this module will create a construction function which returns new object references with the given field values. These references all respond to lvalue methods that access or modify the values stored.

This Perl module allows you to split data into records by not only specifying what you wish to split the data on, but also by specifying an "unless" regular expression. If the text in question matches the "unless" regex, it will not be split there. This allows us to do things like split on newlines unless newlines are embedded in quotes.

This package provides a lexical analyzer for Perl5.

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.

Some Perl modules need to ship C libraries together with their Perl code. Although there are mechanisms to compile and link (or glue) C code in your Perl programs, there isn't a clear method to compile standard, self-contained C libraries. This module main goal is to help in that task.

This package trims the first components of the displayed filename to deal with excessively long ones.

Devel::LexAlias provides the ability to alias a lexical variable in a subroutines scope to one of your choosing.

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".

Exporter::Lite is an alternative to Exporter, intended to provide a lightweight subset of the most commonly-used functionality. It supports import(), @EXPORT and @EXPORT_OK and not a whole lot else.

This module brings the speed advantages of Set::IntSpan (written by Steven McDougall) to arrays. Uses include manipulating grades, routing tables, or any other situation where you have mutually exclusive ranges of integers that map to given values.

This module disables bareword filehandles.

This module allows you to execute code when perl finished compiling the surrounding scope.

Moose is a complete object system for Perl 5. It provides keywords for attribute declaration, object construction, inheritance, and maybe more. With Moose, you define your class declaratively, without needing to know about blessed hashrefs, accessor methods, and so on. You can concentrate on the logical structure of your classes, focusing on "what" rather than "how". A class definition with Moose reads like a list of very concise English sentences.

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

Module::Manifest is a simple utility module created originally for use in Module::Inspector.

It can load a MANIFEST file that comes in a Perl distribution tarball, examine the contents, and perform some simple tasks. It can also load the MANIFEST.SKIP file and check that.

This Perl module provides a central location for modules to report monitoring metrics, such as counters of the number of times interesting events have happened, and programs to collect up and send those metrics to monitoring services.

Config::INI is a module that facilates the reading and writing of .ini-style configuration files.

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 module provides a file handle that hides the beginning of a file, by modifying the seek() and tell() calls.
