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!

Sub::Install makes it easy to install subroutines into packages without the unsightly mess of C<no strict> or typeglobs lying about where just anyone can see them.

This module provides a general-purpose date and datetime type for perl.

Manipulating stashes (Perl's symbol tables) is occasionally necessary, but incredibly messy, and easy to get wrong. This module hides all of that behind a simple API.

This package provides the Statistics::PCA module, an implementation of Principal Component Analysis (PCA).

Assigns a new name to referenced sub. If package specification is omitted in the name, then the current package is used. The return value is the sub.

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

The File::LibMagic module is a simple perl interface to libmagic from the file package.

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 provides a simple syntax for creating object classes.

This module is an implementation of the BGP-4 inter-domain routing protocol. It encapsulates all of the functionality needed to establish and maintain a BGP peering session and exchange routing update information with the peer. It aims to provide a simple API to the BGP protocol for the purposes of automation, logging, monitoring, testing, and similar tasks using the power and flexibility of perl. The module does not implement the functionality of a RIB (Routing Information Base) nor does it modify the kernel routing table of the host system. However, such operations could be implemented using the API provided by the module.

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

This module may be used to convert from under_score text to CamelCase and back again.

This Perl module provides a central location for modules to report monitoring metrics, such as counters of the number of times interesting events have happened, and programs to collect up and send those metrics to monitoring services.

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

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.

A shared memory cache through an mmap'ed file. It's core is written in C for performance. It uses fcntl locking to ensure multiple processes can safely access the cache at the same time. It uses a basic LRU algorithm to keep the most used entries in the cache.

Devel::StackTrace::AsHTML adds as_html method to Devel::StackTrace which displays the stack trace in beautiful HTML, with code snippet context and function parameters. If you call it on an instance of Devel::StackTrace::WithLexicals, you even get to see the lexical variables of each stack frame.

This module converts Perl data structures to JSON and vice versa using either JSON::XS or JSON::PP.

The namespace::autoclean pragma will remove all imported symbols at the end of the current package's compile cycle. Functions called in the package itself will still be bound by their name, but they won't show up as methods on your class or instances. It is very similar to namespace::clean, except it will clean all imported functions, no matter if you imported them before or after you used the pragma. It will also not touch anything that looks like a method.

IO::String is an IO::File (and IO::Handle) compatible class that reads or writes data from in-core strings.

The Params::Validate module allows you to validate method or function call parameters to an arbitrary level of specificity.

Crypt::UnixCrypt_XS implements the DES-based Unix crypt function. For those who need to construct non-standard variants of crypt, the various building blocks used in crypt are also supplied separately.

This package is a plugin to tidyall allowing integration with the Test::Count module, to keep track of the number of tests in a test file.
