Class:Unload unloads a given class by clearing out its symbol table and removing it from %INC.

This is Graph, a Perl module for dealing with graphs, the abstract data structures.

Loading MooX::StrictConstructor makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it dies.

Sub::Identify allows you to retrieve the real name of code references.

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

perlcritic is a Perl source code analyzer. It is the executable front-end to the Perl::Critic engine, which attempts to identify awkward, hard to read, error-prone, or unconventional constructs in your code. Most of the rules are based on Damian Conway's book "Perl Best Practices". However, perlcritic is not limited to enforcing PBP, and it will even support rules that contradict Conway. All rules can easily be configured or disabled to your liking.

Crypt::MySQL emulates the MySQL PASSWORD() function. The module does not depend on an interface to the MySQL database server. This enables the comparison of encrypted passwords without the need for a real MySQL environment.

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.

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 module makes some new features of the Perl 5.14.0 C API available to XS modules running on older versions of Perl. The features are centred around the function cv_set_call_checker, which allows XS code to attach a magical annotation to a Perl subroutine, resulting in resolvable calls to that subroutine being mutated at compile time by arbitrary C code. This module makes cv_set_call_checker and several supporting functions available.

This module opens a config file and parses its contents for you. The format of config files supported by Config::General is inspired by the well known Apache config format and is 100% compatible with Apache configs, but you can also just use simple name/value pairs in your config files. In addition to the capabilities of an Apache config file it supports some enhancements such as here-documents, C-style comments, and multiline options.

This module provides user-defined Unicode properties that deal with width status of East Asian characters, as specified in Unicode® Standard Annex #11.

Meta::Builder is designed to be a generic tool for writing Meta objects. Unlike specialized tools, Meta::Builder makes no assumptions about what metrics you will care about. Meta::Builder also makes it simple for others to extend your meta-object based tools by providing hooks for other packages to add metrics to your meta object.

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

This module simply interpolates option file hints in @ARGV by the contents of the pointed files. This enables option reading from files instead of or additional to the usual reading from the command line.

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.

This module converts Perl data structures to JSON and vice versa.

Lingua::Translit can be used to convert text from one writing system to another, based on national or international transliteration tables. Where possible a reverse transliteration is supported.

Contains the MooX and MooX::Role packages.

Provides several perl modules for date/time manipulation: Time::CTime.pm, Time::JulianDay.pm, Time::ParseDate.pm, Time::Timezone.pm, and Time::DaysInMonth.pm.

This package provides a way to have readable configuration files outside your Perl script. Configurations can be imported, sections can be grouped, and settings can be accessed from a tied hash.

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.

The intent of File::ShareDir is to provide a companion to Class::Inspector and File::HomeDir. Quite often you want or need your Perl module to have access to a large amount of read-only data that is stored on the file-system at run-time. Once the files have been installed to the correct directory, you can use File::ShareDir to find your files again after the installation.

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.
