File::Grep provides similar functionality as perl's builtin grep, map, and foreach commands, but iterating over a passed filelist instead of arrays. While trivial, this module can provide a quick dropin when such functionality is needed.

This module implements the Perl foreign function interface XS for C++; it is a thin layer over plain XS.

This package provides a Perl module for TrueType/OpenType font hacking. It supports reading, processing and writing of the following tables: GDEF, GPOS, GSUB, LTSH, OS/2, PCLT, bsln, cmap, cvt, fdsc, feat, fpgm, glyf, hdmx, head, hhea, hmtx, kern, loca, maxp, mort, name, post, prep, prop, vhea, vmtx and the reading and writing of all other table types.

Config::Any provides a facility for Perl applications and libraries to load configuration data from multiple different file formats. It supports XML, YAML, JSON, Apache-style configuration, and Perl code.

While Mouse attributes provide a way to name your accessors, readers, writers, clearers and predicates, MouseX::NativeTraits provides commonly used attribute helper methods for more specific types of data.

The namespace::clean pragma will remove all previously declared or imported symbols at the end of the current package's compile cycle. Functions called in the package itself will still be bound by their name, but they won't show up as methods on your class or instances.

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.

JSON::Parse is a module for parsing JSON. It offers parse_json which takes a string containing JSON and returns an equivalent Perl structure, valid_json which returns true or false depending on whether the JSON is correct or not, assert_valid_json which produces a descriptive fatal error if the JSON is invalid, and so on.

Given a list of Perl modules/filenames, this module makes require and use statements fail (no matter whether the specified files/modules are installed or not).

Moo is an extremely light-weight Object Orientation system. It allows one to concisely define objects and roles with a convenient syntax that avoids the details of Perl's object system. Moo contains a subset of Moose and is optimised for rapid startup.

Sometimes you need to test what happens when a given module is not installed. This module provides a way of temporarily hiding installed modules from perl's require mechanism. The Module::Mask object adds itself to @INC and blocks require calls to restricted modules.

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.

Text::Table renders plaintext tables.

This Perl module provides Unicode normalization forms.

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

Devel::OverloadInfo returns information about overloaded operators for a given class (or object), including where in the inheritance hierarchy the overloads are declared and where the code implementing it is.

Adds support on top of MooseX::Traits for class precedence search for traits and some extra attributes.

ExtUtils::CppGuess attempts to guess the C++ compiler that is compatible with the C compiler used to build perl.

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

DateTime is a class for the representation of date/time combinations. It represents the Gregorian calendar, extended backwards in time before its creation (in 1582).

Display Perl variables and objects on screen, properly formatted (to be inspected by a human).

This module adds the ability to quickly create new types of tie objects without creating a complete class. It does so in such a way as to try and make the programmers life easier when it comes to single-use ties that I find myself wanting to use from time-to-time.

The Tie::Simple package is actually a front-end to other classes which really do all the work once tied, but this package does the dwimming to automatically figure out what you're trying to do.

It's boring to deal with opening files for IO, converting strings to handle-like objects, and all that. With Mixin::Linewise::Readers and Mixin::Linewise::Writers, you can just write a method to handle handles, and methods for handling strings and file names are added for you.

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