Date::Range is a library to work with date ranges. It can be used to determine whether a given date is in a particular range, or what the overlap between two ranges are.

This module replaces the standard localtime and gmtime functions with implementations that return objects. It does so in a backwards-compatible manner, so that using these functions as documented will still work as expected.

Test::Inter is another framework for writing test scripts, which offer the ability to access specific tests in a reasonably interactive fashion, primarily for debugging purposes. Much of the syntax is loosely inspired by Test::More.

This module provides functions that are the inverse of built-in perl functions localtime() and gmtime(). They accept a date as a six-element array, and return the corresponding time(2) value in seconds since the system epoch.

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.

The "mro" namespace provides several utilities for dealing with method resolution order and method caching in general in Perl 5.9.5 and higher. This module provides those interfaces for earlier versions of Perl (back to 5.6.0).

This package provides functions to convert between Roman and Arabic algorisms. It supports both conventional Roman algorisms (which range from 1 to 3999) and Milhar Romans, a variation which uses a bar across the algorism to indicate multiplication by 1000.

This module implements a Perl interface to the libxml2 library which provides interfaces for parsing and manipulating XML files. This module allows Perl programmers to make use of the highly capable validating XML parser and the high performance DOM implementation.

DBD::SQLite is a Perl DBI driver for SQLite, that includes the entire thing in the distribution. So in order to get a fast transaction capable RDBMS working for your Perl project you simply have to install this module, and nothing else.

The Digest::MD5 module allows you to use the MD5 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.

Email::MIME is an extension of the Email::Simple module, to handle MIME encoded messages. It takes a message as a string, splits it up into its constituent parts, and allows you access to various parts of the message. Headers are decoded from MIME encoding.

This module provides a Perl interface to the iconv() codeset conversion function, as defined by the Single UNIX Specification. For more details see the POD documentation embedded in the file Iconv.pm, which will also be installed as Text::Iconv(3) man page.

Test::Class provides a simple way of creating classes and objects to test your code in an xUnit style.

Built using Test::Builder, it was designed to work with other Test::Builder based modules (Test::More, Test::Differences, Test::Exception, etc.).

This module provides functions to percent-encode and percent-decode URI strings as defined by RFC 3986. Percent-encoding URI's is informally called URI escaping. This is the terminology used by this module, which predates the formalization of the terms by the RFC by several years.

A naive imperative JSON parser in pure Raku (but with direct access to nqp:: ops), to evaluate performance against JSON::Tiny. It is a drop-in replacement for JSON::Tiny's from-json and to-json subs, but it offers a few extra features.

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 Perl module implements Perl hashes that preserve the order in which the hash elements were added. The order is not affected when values corresponding to existing keys in the IxHash are changed. The elements can also be set to any arbitrary supplied order. The familiar perl array operations can also be performed on the IxHash.

Data::Float is about the native floating point numerical data type. A floating point number is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native floating point type, classification functions and functions to manipulate floating point values at a low level.

Pod::Parser is a base class for creating POD filters and translators. It handles most of the effort involved with parsing the POD sections from an input stream, leaving subclasses free to be concerned only with performing the actual translation of text.

NOTE: This module is considered legacy. New projects should prefer Pod::Simple instead.

This module offers some high level convenience functions for accessing web pages on SSL servers (for symmetry, the same API is offered for accessing http servers, too), an sslcat() function for writing your own clients, and finally access to the SSL api of the SSLeay/OpenSSL package so you can write servers or clients for more complicated applications.

Test::Mock is a module that works alongside the standard Test module to help you write tests when you want to verify what methods are called on an object, while still having calls to undefined methods die. You get started just as normal with the test file, but also add a use statement for Test::Mock.

This module attempts to answer, as accurately as it can, one of the nastiest technical questions there is: am I on the internet?

A host of networking and security issues make this problem very difficult. There are firewalls, proxies (both well behaved and badly behaved). We might not have DNS. We might not have a network card at all!

JSON::Parse is a module for parsing JSON. It offers parse_json which takes a string containing JSON and returns an equivalent Perl structure, valid_json which returns true or false depending on whether the JSON is correct or not, assert_valid_json which produces a descriptive fatal error if the JSON is invalid, and so on.

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.
