This module attempts to recover from people calling UNIVERSAL::isa as a function.

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

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.

Number::Format is a library for formatting numbers. Functions are provided for converting numbers to strings in a variety of ways, and to convert strings that contain numbers back into numeric form. The output formats may include thousands separators - characters inserted between each group of three characters counting right to left from the decimal point. The characters used for the decimal point and the thousands separator come from the locale information or can be specified by the user.

Env::Path presents an object-oriented interface to path variables, defined as that subclass of environment variables which name an ordered list of file system elements separated by a platform-standard separator.

This package provides real threads for Perl.

PadWalker is a module which allows you to inspect (and even change) lexical variables in any subroutine which called you. It will only show those variables which are in scope at the point of the call. PadWalker is particularly useful for debugging.

Perl module for using special zip files (called Perl ARchives) as libraries from which Perl modules can be loaded.

This package provides a set of numeric types to be used in Moo-based classes, adapted from MooseX::Types::Common::Numeric.

This package eases the writing of command line utilities, accepting commands and subcommands and so on. These commands can form a tree, which is mirrored in the package structure. On invocation, each command along the path through the tree (starting from the top-level command through to the most specific one) is instantiated.

This policy checks for perlsecret operators in your code and warns you about them. You can override the secrets that are allowed or disallowed using the parameters allow_secrets and disallow_secrets. The default is to simply disallow everything.

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.

Class::ErrorHandler provides an error-handling mechanism that is generic enough to be used as the base class for a variety of OO classes. Subclasses inherit its two error-handling methods, error and errstr, to communicate error messages back to the calling program.

Role::Tiny is a minimalist role composition tool.

Devel::Symdump provides access to the perl symbol table.

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 package provides a data pack for Business::ISBN. These data are generated from the RangeMessage.xml file provided by the ISBN Agency.

PPIx::Utilities is a collection of functions for dealing with PPI objects, many of which originated in Perl::Critic. They are organized into modules by the kind of PPI class they relate to, by replacing the "PPI" at the front of the module name with "PPIx::Utilities", e.g. functionality related to PPI::Nodes is in PPIx::Utilities::Node.

This Perl module provides various functions to quickly sort arrays by one or multiple calculated keys.

This package provides the docmake command-line tool, and the App::XML::DocBook::Docmake and App::XML::DocBook::Builder Perl modules.

It translates DocBook/XML mark-up into various other documentation formats such as XHTML, RTF, PDF, and XSL-FO, using the more low-level tools. It aims to be a replacement for xmlto.

Lexical::Persistence introduces persistent lexical variable values for arbitrary calls.

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 is a library for generating letters, building HTML pages, or filling in templates generally. A template is a piece of text that has little Perl programs embedded in it here and there. When you fill in a template, you evaluate the little programs and replace them with their values.

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