This way of associating structs with Perl space objects is designed to supersede Perl's builtin T_PTROBJ with something that is extensible (structs can be associated with any data type) and opaque (the C pointer is neither visible nor modifiable from Perl space).

This module implements most of `strptime(3)`, the POSIX function that is the reverse of `strftime(3)`, for `DateTime`. While `strftime` takes a `DateTime` and a pattern and returns a string, `strptime` takes a string and a pattern and returns the `DateTime` object associated.

Text::Tabs will add or remove tabs from a document. Text::Wrap will reformat lines into paragraphs.

Config::Simple is a class representing configuration file object. It supports several configuration file syntax and tries to identify the file syntax automatically. The library supports parsing, updating and creating configuration files.

The PPI module parses, analyzes and manipulates Perl code.

List::MoreUtils provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.

The Error package provides two interfaces. Firstly Error provides a procedural interface to exception handling. Secondly Error is a base class for errors/exceptions that can either be thrown, for subsequent catch, or can simply be recorded.

Text::CSV provides facilities for the composition and decomposition of comma-separated values. An instance of the Text::CSV class can combine fields into a CSV string and parse a CSV string into fields.

This package provides Digest::SHA3, an implementation of the NIST SHA-3 message digest algorithm for use by Perl programs.

This package lets you declare types using short names, but behind the scenes it namespaces all your type declarations, effectively prevent name clashes between packages.

Parse::CPAN::Meta is a parser for META.json and META.yml files, using JSON::PP and/or CPAN::Meta::YAML.

This module exports all of the functions that either List::Util or List::MoreUtils defines, with preference to List::Util.

Provides several perl modules for date/time manipulation: Time::CTime.pm, Time::JulianDay.pm, Time::ParseDate.pm, Time::Timezone.pm, and Time::DaysInMonth.pm.

App::Nopaste provides easy access to any pastebin.

The Devel::StackTrace module contains two classes, Devel::StackTrace and Devel::StackTrace::Frame. These objects encapsulate the information that can be retrieved via Perl's caller() function, as well as providing a simple interface to this data.

This module implements an expiry policy for Memoize that follows LRU semantics, that is, the last n results, where n is specified as the argument to the CACHESIZE parameter, will be cached.

This Digest::Perl::MD5 has the same interface as the much faster Digest::MD5, but it's a pure Perl implementation of MD5. Because of this it is slow but it works without C code.

This module is an alternative to String::Trim. Instead of a single trim function, this module provides several from which you can choose on, depending on your needs.

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.

The first priority of Set::Scalar is to be a convenient interface to sets (as in: unordered collections of Perl scalars). While not designed to be slow or big, neither has it been designed to be fast or compact.

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.

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_".

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

The form() subroutine may be exported from the module. It takes a series of format (or "picture") strings followed by replacement values, interpolates those values into each picture string, and returns the result. The effect is similar to the inbuilt perl format mechanism, although the field specification syntax is simpler and some of the formatting behaviour is more sophisticated.
