Async::Interrupt implements a single feature only of interest to advanced perl modules, namely asynchronous interruptions (think "UNIX signals", which are very similar).

Sometimes, modules wish to run code asynchronously (in another thread, or from a signal handler), and then signal the perl interpreter on certain events. One common way is to write some data to a pipe and use an event handling toolkit to watch for I/O events. Another way is to send a signal. Those methods are slow, and in the case of a pipe, also not asynchronous - it won't interrupt a running perl interpreter.

This module implements asynchronous notifications that enable you to signal running perl code from another thread, asynchronously, and sometimes even without using a single syscall.

This package provides a Perl library that allows refreshing classes at runtime.

File::Zglob provides a traditional Unix glob functionality; it returns a list of file names that match the given pattern. For instance, it supports the **/*.pm form.

The Regexp::Grammars module adds a small number of new regex constructs that can be used within Perl 5.10 patterns to implement complete recursive-descent parsing. It allows you to go beyond matching complex, nested and recursive structures, and allows you to parse and extract hierarchical data from it.

The alias module loads the class you specify and exports into your namespace a subroutine that returns the class name. You can explicitly alias the class to another name or, if you prefer, you can do so implicitly.

This module opens a config file and parses its contents for you. The format of config files supported by Config::General is inspired by the well known Apache config format and is 100% compatible with Apache configs, but you can also just use simple name/value pairs in your config files. In addition to the capabilities of an Apache config file it supports some enhancements such as here-documents, C-style comments, and multiline options.

This is a module for computing the difference between two files, two strings, or any other two lists of things. It uses an intelligent algorithm similar to (or identical to) the one used by the Unix "diff" program. It is guaranteed to find the *smallest possible* set of differences.

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.

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

This Perl module facilitates the creation and modification of PDF files.

This module simply interpolates option file hints in @ARGV by the contents of the pointed files. This enables option reading from files instead of or additional to the usual reading from the command line.

This package allows you to define different interpreters for different test scripts with Test::Run.

This package allows you to analyze tests from the command line using Test::Run.

Loading MooX::StrictConstructor makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it dies.

This module solves the problem of having to continually write accessor methods for your objects that perform standard tasks.

This package provides a way to sort revision-like numbers.

IO::All combines all of the best Perl IO modules into a single nifty object oriented interface to greatly simplify your everyday Perl IO idioms. It exports a single function called io, which returns a new IO::All object. And that object can do it all!

Data::OptList provides a simple syntax for name/value option pairs.

This module generalises the mechanism of the wantarray function, allowing a function to determine in some detail how its return value is going to be immediately used.

This module provides some extra datatypes that are used by common serialisation formats such as JSON or CBOR.

PAR::Dist is a toolkit to create and manipulate PAR distributions.

Module::Build is a system for building, testing, and installing Perl modules; it used to be part of Perl itself until version 5.22, which dropped it. It is meant to be an alternative to ExtUtils::MakeMaker. Developers may alter the behavior of the module through subclassing in a much more straightforward way than with MakeMaker. It also does not require a make on your system---most of the Module::Build code is pure-Perl.

Class::ErrorHandler provides an error-handling mechanism that is generic enough to be used as the base class for a variety of OO classes. Subclasses inherit its two error-handling methods, error and errstr, to communicate error messages back to the calling program.

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.
