URI::Fetch is a smart client for fetching HTTP pages, notably syndication feeds (RSS, Atom, and others), in an intelligent, bandwidth- and time-saving way.

The File::List module crawls the directory tree starting at the provided base directory and can return files (and/or directories if desired) matching a regular expression.

This module provides the most commonly used testing functions, along with automatically turning on strict and warning and gives a bit more fine-grained control over test suites.

This module implements a wrapper for Net::SMTP, enabling over-SSL/STARTTLS support. This module inherits most of all the methods from Net::SMTP(2.X).

This module implements the Brew edit distance that is very close to the dynamic programming technique used for the Wagner-Fischer (and so for the Levenshtein) edit distance.

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.

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.

SVG::Plot is a simple 2D chart plotter for Raku. It currently supports bars, stacked bars, lines and points (both equally spaced with optional labels, or xy plots).

SOAP::Lite is a collection of Perl modules that provide a simple and lightweight interface to the SOAP, both on client and server side.

Feed::Find implements feed auto-discovery for finding syndication feeds, given a URI. It will discover the following feed formats: RSS 0.91, RSS 1.0, RSS 2.0, Atom.

Test::Base gives a way to trivially write your own test framework base class. It concentrates on offering reusable data driven patterns, so that you can write tests with a minimum of code.

YAML::Syck provides a Perl interface to the libsyck data serialization library. It exports the Dump and Load functions for converting Perl data structures to YAML strings, and the other way around.

The mix_class function provided by this module dynamically generates anonymous classes with specified inheritance. This is useful where an incomplete class requires use of a mixin in order to become instantiable.

This module is for manipulating data as hierarchical tag/value pairs (Structured TAGs or Simple Tree AGgregates). These datastructures can be represented as nested arrays, which have the advantage of being native to Perl.

This is a very simple HTTP/1.1 client, designed for doing simple requests without the overhead of a large framework like LWP::UserAgent. It supports proxies and redirection. It also correctly resumes after EINTR.

This module aims to comply exactly to the https://www.w3.org/TR/xpath and yet allow extensions to be added in the form of functions. It also provides the command xpath.

This package consists of a Perl module for date calculations based on the Gregorian calendar, thereby complying with all relevant norms and standards: ISO/R 2015-1971, DIN 1355 and, to some extent, ISO 8601 (where applicable).

This module provide functions that takes a list of values as their argument and produces a string as its result. The string contains Perl code that, when "eval"ed, produces a deep copy of the original arguments.

Text::Glob implements glob(3) style matching that can be used to match against text, rather than fetching names from a file system. If you want to do full file globbing use the File::Glob module instead.

HTML::Tidy is an HTML checker in a handy dandy object. It's meant as a replacement for HTML::Lint, which is written in Perl but is not nearly as capable as HTML::Tidy.

Testing code which forks is problematic because each test has a number associated with it. Coordinating the test number amongst the parent and child processes is complicated. Test::Fork provides a function to smooth over the complications.

This module is primarily (but not exclusively) for use in test scripts: A block eval configurable and extensible but by default trapping STDOUT, STDERR, warnings, exceptions, would-be exit codes, and return values from boxed blocks of test code.

Alien::SDL can be used to detect and get configuration settings from an installed SDL and related libraries. Based on your platform it offers the possibility to download and install prebuilt binaries or to build SDL & co.: from source codes.

Data::UUID provides a framework for generating Universally Unique Identifiers (UUIDs), also known as Globally Unique Identifiers (GUIDs). A UUID is 128 bits long, and is guaranteed to be different from all other UUIDs/GUIDs generated until 3400 CE.
