The Inline module allows you to put source code from other programming languages directly (inline) in a Perl script or module. The code is automatically compiled as needed, and then loaded for immediate access from Perl.

DateTime::Format::Flexible attempts to take any string you give it and parse it into a DateTime object.

Crypt::RandPasswd provides three functions that can be used to generate random passwords, constructed from words, letters, or characters. This code is a Perl implementation of the Automated Password Generator standard, like the program described in "A Random Word Generator For Pronounceable Passwords". This code is a re-engineering of the program contained in Appendix A of FIPS Publication 181, "Standard for Automated Password Generator".

Mail::Sendmail is a pure perl module that provides a simple means to send email from a perl script. The module only requires Perl5 and a network connection.

MIME::Base64 module provides functions to encode and decode strings into and from the base64 encoding specified in RFC 2045 - MIME (Multipurpose Internet Mail Extensions). The base64 encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. A 65-character subset ([A-Za-z0-9+/=]) of US-ASCII is used, enabling 6 bits to be represented per printable character.

This module provides a few useful functions for manipulating module names. Its main aim is to centralise some of the functions commonly used by modules that manipulate other modules in some way, like converting module names to relative paths.

You use Tie::Cycle to go through a list over and over again. Once you get to the end of the list, you go back to the beginning.

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

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.

Sys::Hostname::Long tries very hard to get the full hostname of a system.

This module provides Path::Tiny types for Moose, Moo, etc. It handles two important types of coercion: coercing objects with overloaded stringification, and coercing to absolute paths. It also can check to ensure that files or directories exist.

This package is a plugin to tidyall allowing integration with the Test::Count module, to keep track of the number of tests in a test file.

This class provides several methods for host name resolution. It is designed to be used with event loops. Names are resolved by your system's native getaddrinfo(3) implementation, called in a separate thread to avoid blocking the entire application. Threading overhead is limited by using system threads instead of Perl threads.

This module understands the formats used by PostgreSQL for its DATE, TIME, TIMESTAMP, and INTERVAL data types. It can be used to parse these formats in order to create DateTime or DateTime::Duration objects, and it can take a DateTime or DateTime::Duration object and produce a string representing it in a format accepted by PostgreSQL.

Chaolin Zhang's Perl Library (czplib) contains assorted functions and data structures for processing and analysing genomic and bioinformatics data.

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

This module is a factory for dispensing Tree::Simple::Visitor::* objects.

File::ShareDir::Install allows you to install read-only data files from a distribution. It is a companion module to File::ShareDir, which allows you to locate these files after installation.

Config::Any provides a facility for Perl applications and libraries to load configuration data from multiple different file formats. It supports XML, YAML, JSON, Apache-style configuration, and Perl code.

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.

Calling Perl's in-built system function is easy, determining if it was successful is hard. Let's face it, $? isn't the nicest variable in the world to play with, and even if you do check it, producing a well-formatted error string takes a lot of work.

IPC::System::Simple takes the hard work out of calling external commands.

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).

This module does not provide any methods. Simply loading it changes the default naming policy for the loading class so that accessors are separated into get and set methods. The get methods have the same name as the accessor, while set methods are prefixed with "_set_".

This module implements the C3 algorithm, which aims to provide a sane method resolution order under multiple inheritance.
