This module allows you to build a variable package that contains a package template and can use it to build variant packages at runtime. Your variable package will export a subroutine which will build a variant package, combining its arguments with the template, and return the name of the new variant package. The implementation does not care about what kind of packages it builds, be they simple function exporters, classes, singletons or something else.

This module exports a single function: ttie. It ties a variable to a type constraint, ensuring that whatever values stored in the variable will conform to the type constraint. If the type constraint has coercions, these will be used if necessary to ensure values assigned to the variable conform.

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.

Hook::LexWrap allows you to install a pre- or post-wrapper (or both) around an existing subroutine. Unlike other modules that provide this capacity (e.g., Hook::PreAndPost and Hook::WrapSub), Hook::LexWrap implements wrappers in such a way that the standard caller function works correctly within the wrapped subroutine.

This Perl module provides Chinese encodings that are not part of Perl by default, including "BIG5-1984", "BIG5-2003", "BIG5PLUS", "BIG5EXT", "CCCII", "EUC-TW", "CNS11643-*", "GB18030", and "UNISYS".

Sub::Exporter is an incredibly powerful module, but with that power comes great responsibility, as well as some runtime penalties. This module is a "Sub::Exporter" wrapper that will let your users just use Exporter if all they are doing is picking exports, but use "Sub::Exporter" if your users try to use "Sub::Exporter"'s more advanced features, like renaming exports, if they try to use them.

File::ShareDir::Install allows you to install read-only data files from a distribution. It is a companion module to File::ShareDir, which allows you to locate these files after installation.

This module abstracts out the process of choosing one of several underlying implementations for a module. This can be used to provide XS and pure Perl implementations of a module, or it could be used to load an implementation for a given OS or any other case of needing to provide multiple implementations.

This module provides some XS functions to assist in writing syntax modules that provide new perl-visible syntax, primarily for authors of keyword plugins using the PL_keyword_plugin hook mechanism.

Config::Tiny is a Perl class to read and write .ini style configuration files with as little code as possible, reducing load time and memory overhead.

This module is primarily for reading human written files, and anything we write shouldn't need to have documentation/comments. If you need something with more power move up to Config::Simple, Config::General or one of the many other Config::* modules.

MooseX::Role::WithOverloading allows you to write a Moose::Role which defines overloaded operators and allows those overload methods to be composed into the classes/roles/instances it's compiled to, where plain Moose::Roles would lose the overloading.

This toolkit primarily provides modules for performing both traditional and object-oriented i/o) on things *other* than normal filehandles; in particular, IO::Scalar, IO::ScalarArray, and IO::Lines.

This module tries to make install path resolution as easy as possible.

Dates are complex enough without times and timezones. This module may be used to create simple date objects. It handles validation, interval arithmetic, and day-of-week calculation. It does not deal with hours, minutes, seconds, and time zones.

Mouse is a Moose compatible object system that implements a subset of the functionality for reduced startup time.

This module implements Spreadsheet::XLSX parsing Microsoft Excel 2007 xlsx files.

This module applies roles to make a subclass instead of manually setting up a subclass.

This module is a factory for dispensing Tree::Simple::Visitor::* objects.

This module provide a convenient way to create directories of arbitrary depth and to delete an entire directory subtree from the file system.

Guard implements so-called guards. A guard is something (usually an object) that "guards" a resource, ensuring that it is cleaned up when expected.

Specifically, this module supports two different types of guards: guard objects, which execute a given code block when destroyed, and scoped guards, which are tied to the scope exit.

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.

This module acts as a layer between Exporter and modules which consume exports. It is feature-compatible with Exporter, plus some much needed extras. You can use this to import symbols from any exporter that follows Exporters specification. The exporter modules themselves do not need to use or inherit from the Exporter module, they just need to set @EXPORT and/or other variables.

Crypt::CBC is a Perl-only implementation of the cryptographic Cipher Block Chaining (CBC) mode. In combination with a block cipher such as Crypt::Rijndael you can encrypt and decrypt messages of arbitrarily long length. The encrypted messages are compatible with the encryption format used by SSLeay.

Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for names with the same pronunciation to be encoded to the same representation so that they can be matched despite minor differences in spelling.

This module implements the original soundex algorithm developed by Robert Russell and Margaret Odell, patented in 1918 and 1922, as well as a variation called "American Soundex" used for US census data, and current maintained by the National Archives and Records Administration (NARA).
