Given a list of scalars or reference variables, Data::Dumper writes out their contents in Perl syntax. The references can also be objects. The content of each variable is output in a single Perl statement. It handles self-referential structures correctly.

Because Moose roles serve many different masters, they usually provide only the least common denominator of functionality. To empower roles further, more configurability than -alias and -excludes is required. Perhaps your role needs to know which method to call when it is done processing, or what default value to use for its url attribute. Parameterized roles offer a solution to these (and other) kinds of problems.

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

The purpose of the PPIx-Regexp package is to parse regular expressions in a manner similar to the way the PPI package parses Perl. This class forms the root of the parse tree, playing a role similar to PPI::Document.

lib::relative module proposes a more straightforward method than adding a path to @INC: take a path relative to the current file, absolutize it, and add it to @INC.

Data::Perl is a container class for the following classes:

• Data::Perl::Collection::Hash

• Data::Perl::Collection::Array

• Data::Perl::String

• Data::Perl::Number

• Data::Perl::Counter

• Data::Perl::Bool

• Data::Perl::Code

This module is about the native integer numerical data type. A native integer is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native integer type. Both signed and unsigned representations are handled.

This is a Moose role which provides an alternate constructor for creating objects using parameters passed in from the command line.

File::Find is great, but constructing the wanted routine can sometimes be a pain. File::Finder provides a wanted-writer, using syntax that is directly mappable to the find(1) command's syntax.

A File::Finder object contains a hash of File::Find options, and a series of steps that mimic find's predicates. Initially, a File::Finder object has no steps. Each step method clones the previous object's options and steps, and then adds the new step, returning the new object. In this manner, an object can be grown, step by step, by chaining method calls. Furthermore, a partial sequence can be created and held, and used as the head of many different sequences.

This module verifies if requirements described in a CPAN::Meta object are present.

Term::ProgressBar provides a simple progress bar on the terminal, to let the user know that something is happening, roughly how much stuff has been done, and maybe an estimate at how long remains.

This package provides some compilation helpers so you can link Fortran libraries into C libraries.

This module is for manipulating data as hierarchical tag/value pairs (Structured TAGs or Simple Tree AGgregates). These datastructures can be represented as nested arrays, which have the advantage of being native to Perl.

Test::Run is an improved test harness, originally based on Test::Harness version 2.xx by Michael G. Schwern, Andy Lester and others.

The top-level "Test::Run" by itself does not do much. You should refer to Task::Test::Run::AllPlugins for more detailed instructions.

Text::Tabs will add or remove tabs from a document. Text::Wrap will reformat lines into paragraphs.

Conf::Libconfig is a Perl interface to the libconfig configuration file library. It support scalar, array, and hash data structures just like its C/C++ counterpart. It reduces the effort required to implement a configuration file parser in your Perl programme and allows sharing configuration files between languages.

Sys::SigAction is a Perl extension for Consistent Signal Handling.

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.

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.

This package allows you to make the file verdict (i.e., ok, NOT OK) colorful in test outputs.

String::Formatter is a tool for building sprintf-like formatting routines. It supports named or positional formatting, custom conversions, fixed string interpolation, and simple width-matching.

Authen-Passphrase is the base class for a system of objects that encapsulate passphrases. An object of this type is a passphrase recogniser; its job is to recognise whether an offered passphrase is the right one. For security such passphrase recognisers usually do not themselves know the passphrase they are looking for; they can merely recognise it when they see it. There are many schemes in use to achieve this effect and the intent of this class is to provide a consistent interface to them all. In addition to the base class, this module also contains implementations of several specific passphrase schemes.

This module implements some sane defaults for Perl programs, as defined by two typical specimens of Perl coders.

This module is for reading record-oriented data in a delimited text file. The most common example have records separated by newlines and fields separated by commas or tabs, but this module aims to provide a consistent interface for handling sequential records in a file however they may be delimited.
