IO::Pty provides an interface to allow the creation of a pseudo tty. IO::Pty inherits from IO::Handle and so provides all the methods defined by the IO::Handle package.

This Perl module provides a central location for modules to report monitoring metrics, such as counters of the number of times interesting events have happened, and programs to collect up and send those metrics to monitoring services.

This module runs code after a subroutine call, preserving the context the subroutine would have seen if it were the last statement in the caller.

This package enables you to do generic message logging throughout programs and projects. Every message will be logged with stacktraces, timestamps and so on. You can use built-in handlers immediately, or after the fact when you inspect the error stack. It is highly configurable and lets you even provide your own handlers for dealing with messages.

B::Utils provide helper functions for op tree manipulation.

This module makes the functionality of the perltidy command available to Perl scripts. Any or all of the input parameters may be omitted, in which case the @ARGV array will be used to provide input parameters as described in the perltidy(1) man page.

This package provides the Statistics::PCA module, an implementation of Principal Component Analysis (PCA).

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

This library provides a set of Path::Tiny types and coercions for Specio. These types can be used with Moose, Moo, Params::ValidationCompiler, and other modules.

Collection of classes that wrap fundamental data types that exist in Perl. These classes and methods as they exist today are an attempt to mirror functionality provided by Moose's Native Traits. One important thing to note is all classes currently do no validation on constructor input.

Text::Diff provides a basic set of services akin to the GNU diff utility. It is not anywhere near as feature complete as GNU diff, but it is better integrated with Perl and available on all platforms. It is often faster than shelling out to a system's diff executable for small files, and generally slower on larger files.

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

Date::Calc::XS is an XS wrapper and C library plug-in for Date::Calc.

This module tries to provide a coherent API to bring together the various JSON modules currently on CPAN. This module will allow you to code to any JSON API and have it work regardless of which JSON module is actually installed.

This pragma allows you to declare constants at compile-time. When a constant is used in an expression, Perl replaces it with its value at compile time, and may then optimize the expression further. In particular, any code in an if (CONSTANT) block will be optimized away if the constant is false.

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

This module allows you to manage a set of deprecations for one or more modules.

Term::Encoding is a simple module to detect the encoding of the current terminal expects in various ways.

This package provides a way to sort revision-like numbers.

This module provides a small, fast utility for working with file paths.

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.

Hash::MultiValue is an object (and a plain hash reference) that may contain multiple values per key, inspired by MultiDict of WebOb.

This module provides some extra datatypes that are used by common serialisation formats such as JSON or CBOR.

This module provides a convenient way to perform cleanup or other forms of resource management at the end of a scope. It is particularly useful when dealing with exceptions: the Scope::Guard constructor takes a reference to a subroutine that is guaranteed to be called even if the thread of execution is aborted prematurely. This effectively allows lexically-scoped "promises" to be made that are automatically honoured by perl's garbage collector.
