IO::CaptureOutput provides routines for capturing STDOUT and STDERR from perl subroutines, forked system calls (e.g. system(), fork()) and from XS or C modules.

This module is no longer recommended by its maintainer. Users are advised to try Capture::Tiny instead.

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

Devel::CheckBin is a perl module that checks whether a particular command is available.

Multidimensional disables multidimensional array emulation.

This module provides an interface to layout and image generation of directed and undirected graphs in a variety of formats (PostScript, PNG, etc.) using the dot, neato, twopi, circo, and fdp programs from the Graphviz project. This package is deprecated in favour of GraphViz2.

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

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

This module first checks to see if either Cpanel::JSON::XS or JSON::XS is already loaded, in which case it uses that module. Otherwise it tries to load Cpanel::JSON::XS, then JSON::XS, then JSON::PP in order, and either uses the first module it finds or throws an error.

Regexp patterns related to DefHash, a convention to define things more precisely and uniformly using a hash.

Display Perl variables and objects on screen, properly formatted (to be inspected by a human).

File::ShareDir::Dist finds share directories for distributions. It is a companion module to File::ShareDir.

This package provides a simple Perl library to extract height/width from images.

This module is able to generically format rows of data into tables.

This module exports a single hash (%RE) that stores or generates commonly needed regular expressions. Patterns currently provided include: balanced parentheses and brackets, delimited text (with escapes), integers and floating-point numbers in any base (up to 36), comments in 44 languages, offensive language, lists of any pattern, IPv4 addresses, URIs, and Zip codes.

Text::NeatTemplate provides a simple, middleweight but fast template engine, for when you need speed rather than complex features, yet need more features than simple variable substitution.

Text::TabularDisplay simplifies displaying textual data in a table. The output is identical to the columnar display of query results in the mysql text monitor.

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.

Sometimes you need to test what happens when a given module is not installed. This module provides a way of temporarily hiding installed modules from perl's require mechanism. The Module::Mask object adds itself to @INC and blocks require calls to restricted modules.

The Text::Balanced module can be used to extract delimited text sequences from strings.

This module provides convenience methods that let you easily create DateTime::Set objects for various recurrences, such as "once a month" or "every day". You can also create more complicated recurrences, such as "every Monday, Wednesday and Thursday at 10:00 AM and 2:00 PM".

This package compiles yacc-like Look Ahead LR (LALR) grammars to generate Perl object oriented parser modules.

This module implements the Rijndael cipher which has been selected as the Advanced Encryption Standard. The keysize for Rijndael is 32 bytes. The blocksize is 16 bytes (128 bits). The supported encryption modes are:

• MODE_CBC---Cipher Block Chaining

• MODE_CFB---Cipher feedback

• MODE_CTR---Counter mode

• MODE_ECB---Electronic cookbook mode

• MODE_OFB---Output feedback

Lexical::SealRequireHints prevents leakage of lexical hints

This module provides functions for fast and correct file slurping and spewing. All functions are optionally exported.
