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

Multidimensional disables multidimensional array emulation.

This module tries to find middle ground between one at a time and all at once processing of data sets. The purpose of this module is to avoid the overhead of implementing an iterative api when this isn't necessary, without breaking forward compatibility in case that becomes necessary later on.

This module applies roles to make a subclass instead of manually setting up a subclass.

This package allows you to stop processing the entire test suite after the first failure, instead of going all the way through it.

This module provides tools to deal with International Standard Serial Numbers.

ExtUtils::PkgConfig is a very simplistic interface to the pkg-config utility, intended for use in the Makefile.PL of perl extensions which bind libraries that pkg-config knows. It is really just boilerplate code that you would have written yourself.

The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.

MIME::Base64 module provides functions to encode and decode strings into and from the base64 encoding specified in RFC 2045 - MIME (Multipurpose Internet Mail Extensions). The base64 encoding is designed to represent arbitrary sequences of octets in a form that need not be humanly readable. A 65-character subset ([A-Za-z0-9+/=]) of US-ASCII is used, enabling 6 bits to be represented per printable character.

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.

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.

Scalar::String is about the string part of plain Perl scalars. A scalar has a string value, which is notionally a sequence of Unicode codepoints but may be internally encoded in either ISO-8859-1 or UTF-8. In places, more so in older versions of Perl, the internal encoding shows through. To fully understand Perl strings it is necessary to understand these implementation details. This module provides functions to classify a string by encoding and to encode a string in a desired way. The module is implemented in XS, with a pure Perl backup version for systems that cannot handle XS.

Mouse is a Moose compatible object system that implements a subset of the functionality for reduced startup time.

This module provides a basic way to discover if a piece of perl code is allocating perl data and not releasing them again.

File::Remove::remove removes files and directories. It acts like /bin/rm, for the most part. Although unlink can be given a list of files, it will not remove directories; this module remedies that. It also accepts wildcards, * and ?, as arguments for file names.

A CPAN::Meta::Requirements object models a set of version constraints like those specified in the META.yml or META.json files in CPAN distributions, and as defined by CPAN::Meta::Spec. It can be built up by adding more and more constraints, and will reduce them to the simplest representation.

PerlIO::utf8_strict provides a fast and correct UTF-8 PerlIO layer. Unlike Perl's default :utf8 layer it checks the input for correctness.

With this module, you can calculate terminal character widths that vary by locale. This module supplies features similar to wcwidth(3) and wcswidth(3) in C language.

Ref::Util introduces several functions to help identify references in a smarter (and usually faster) way. The difference with conventional approach:

• No comparison against a string constant

• Supports blessed variables

• Supports tied variables and magic

• Ignores overloading

• Ignores subtle types

• Usually faster

The Digest::SHA Perl module implements the hash functions of the SHA family. It also provides the shasum binary.

This module overrides CORE::GLOBAL::require with a code reference in a way that plays nice with any existing overloading and ensures the right calling package is in scope.

This module allows one to run a subset of the subtest tests given in a test file.

The module declaration takes a whitelist of the subtests we want to run. Any subtest that doesn't match any of the whitelist items will be skipped (or potentially bypassed).

This module does not provide any methods. Simply loading it changes the default naming policy for the loading class so that accessors are separated into get and set methods. The get methods have the same name as the accessor, while set methods are prefixed with "_set_".

The Template Toolkit is a collection of modules which implement an extensible template processing system. It was originally designed and remains primarily useful for generating dynamic web content, but it can be used equally well for processing any other kind of text based documents: HTML, XML, POD, PostScript, LaTeX, and so on.
