This module splits a set of data with IDs and arbitrary values into one test file per (key+value) for easy parallelisation.

This module allows you to speed up your sleep(), alarm(), and time() calls.

Moo is an extremely light-weight Object Orientation system. It allows one to concisely define objects and roles with a convenient syntax that avoids the details of Perl's object system. Moo contains a subset of Moose and is optimised for rapid startup.

This module defines a single regex that will match syntactically valid Perl documents, or valid components (such as statements, expressions, blocks, strings, etc.)

This module provides various portable helper functions for module building modules.

This module provides $CWD and @CWD as alternatives to chdir().

This module attempts to emulate the behavior of Class::Accessor::Fast as accurately as possible using the Moose attribute system. The public API of Class::Accessor::Fast is wholly supported, but the private methods are not.

Lexical::SealRequireHints prevents leakage of lexical hints

Simply loading this module makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it calls Moose->throw_error().

This module implement a UDP client for the statsd statistics collector daemon in use at Etsy.com.

The YAML.pm module implements a YAML Loader and Dumper based on the YAML 1.0 specification.

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.

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!

This module provides lexicon-handling modules to read from other localization formats, such as Gettext, Msgcat, and so on.

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.

Getopt::Long::Descriptive is yet another Getopt library. It's built atop Getopt::Long, and gets a lot of its features, but tries to avoid making you think about its huge array of options. It also provides usage (help) messages, data validation, and a few other useful features.

Internationalized Domain Names (IDNs) use characters drawn from a large repertoire (Unicode), but IDNA allows the non-ASCII characters to be represented using only the ASCII characters already allowed in so-called host names today (letter-digit-hyphen, /[A-Z0-9-]/i).

Use this module if you just want to convert domain names (or email addresses), using whatever IDNA standard is the best choice at the moment.

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.

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

Authen::DecHpwd implements the SYS$HASH_PASSWORD password hashing function from VMS (also known as LGI$HPWD) and some associated VMS username and password handling functions. The password hashing function is implemented in XS with a pure Perl backup version for systems that cannot handle XS.

Circos is a program for the generation of publication-quality, circularly composited renditions of genomic data and related annotations.

This package provides a package to change terminal modes and perform non-blocking reads.

This module has 3 functions: one to copy files only, one to copy directories only, and one to do either depending on the argument's type.

When an undefined variable is dereferenced, it gets silently upgraded to an array or hash reference (depending of the type of the dereferencing). This behaviour is called autovivification and usually does what you mean but it may be unnatural or surprising because your variables get populated behind your back. This is especially true when several levels of dereferencing are involved, in which case all levels are vivified up to the last, or when it happens in intuitively read-only constructs like exists. The pragma provided by this package lets you disable autovivification for some constructs and optionally throws a warning or an error when it would have happened.
