The purpose of the PPIx-Regexp package is to parse regular expressions in a manner similar to the way the PPI package parses Perl. This class forms the root of the parse tree, playing a role similar to PPI::Document.

SDL Perl is a package of Perl modules that provide both functional and object oriented interfaces to the Simple DirectMedia Layer for Perl5. This package takes some liberties with the SDL API, and attempts to adhere to the spirit of both the SDL and Perl.

Params::Util provides a basic set of importable functions that makes checking parameters easier.

This module provides convenience methods that let you easily create DateTime::Set objects for RFC 2445 style recurrences.

The package provides Perl bindings to OpenGL, GLU and FreeGLUT.

MooseX::Object::Pluggable makes your classes pluggable.

This module exports two functions, nsort and ncmp; they are used in implementing a "natural sorting" algorithm. Under natural sorting, numeric substrings are compared numerically, and other word-characters are compared lexically.

MooseX::Types::LoadableClass provides a ClassName type constraint with coercion to load the class.

This module provides tools to deal with International Standard Book Numbers, including ISBN-10 and ISBN-13.

This module tries to make it easy to build Perl extensions that use functions and typemaps provided by other perl extensions. This means that a perl extension is treated like a shared library that provides also a C and an XS interface besides the perl one.

Hook::LexWrap allows you to install a pre- or post-wrapper (or both) around an existing subroutine. Unlike other modules that provide this capacity (e.g., Hook::PreAndPost and Hook::WrapSub), Hook::LexWrap implements wrappers in such a way that the standard caller function works correctly within the wrapped subroutine.

Mail::RFC822::Address validates email addresses against the grammar described in RFC 822 using regular expressions.

This module automagically generates accessors/mutators for your class.

The Eval::WithLexicals Perl library provides support for lexical scope evaluation. This package also includes the tinyrepl command, which can be used as a minimal Perl read-eval-print loop (REPL).

This module provides a Log::Any adapter to send log messages to screen, with colors and some other features.

The functions exported by this module allow you to open URLs in the user's browser. A set of known commands per OS-name is tested for presence, and the first one found is executed. With an optional parameter, all known commands are checked.

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

This module is meant as a debugging aid. It can be used to make a script complain loudly with stack backtraces when warn()-ing or die()ing.

This package provides functions to format text in various ways like centering, paragraphing, and converting tabs to spaces and spaces to tabs.

This package provides a selection of regular expression subroutines including is_regexp, regexp_seen_evals, regexp_is_foreign, regexp_is_anchored, serialize_regexp, and deserialize_regexp.

Parse::RecDescent can incrementally generate top-down recursive-descent text parsers from simple yacc-like grammar specifications.

Exporter::Tiny supports many of Sub::Exporter's external-facing features including renaming imported functions with the `-as`, `-prefix` and `-suffix` options; explicit destinations with the `into` option; and alternative installers with the `installer` option. But it's written in only about 40% as many lines of code and with zero non-core dependencies.

Data::SExpression parses Lisp S-Expressions into Perl data structures.

DateTime::Format::ISO8601 is a DateTime extension that parses almost all ISO8601 date and time formats.
