The functions exported by this module allow you to open URLs in the user's browser. A set of known commands per OS-name is tested for presence, and the first one found is executed. With an optional parameter, all known commands are checked.

This module understands the W3CDTF date/time format, an ISO 8601 profile, defined at https://www.w3.org/TR/NOTE-datetime. This format is the native date format of RSS 1.0. It can be used to parse these formats in order to create the appropriate objects.

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 provides a simple but extensible way of having plugins for your Perl module.

Module::Install is a package for writing installers for CPAN (or CPAN-like) distributions that are clean, simple, minimalist, act in a strictly correct manner with ExtUtils::MakeMaker, and will run on any Perl installation version 5.005 or newer.

String::Formatter is a tool for building sprintf-like formatting routines. It supports named or positional formatting, custom conversions, fixed string interpolation, and simple width-matching.

This module may be used to convert from under_score text to CamelCase and back again.

This module provides an XS implementation for portions of Class::Load.

Carp::Assert is intended for a purpose like the ANSI C library assert.h.

Manipulating stashes (Perl's symbol tables) is occasionally necessary, but incredibly messy, and easy to get wrong. This module hides all of that behind a simple API.

This module builds on MooseX::Types::DateTime to add additional custom types and coercions. Since it builds on an existing type, all coercions and constraints are inherited.

File::Which was created to be able to get the paths to executable programs on systems under which the `which' program wasn't implemented in the shell.

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

Safe::Hole can execute outside defined subroutines in the original main compartment from the Safe compartment.

This Perl module allows you to split data into records by not only specifying what you wish to split the data on, but also by specifying an "unless" regular expression. If the text in question matches the "unless" regex, it will not be split there. This allows us to do things like split on newlines unless newlines are embedded in quotes.

This module provide functions that takes a list of values as their argument and produces a string as its result. The string contains Perl code that, when "eval"ed, produces a deep copy of the original arguments.

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

This module allows errors from a clan (or family) of modules to appear to originate from the caller of the clan. This is necessary in cases where the clan modules are not classes derived from each other, and thus the Carp.pm module doesn't help.

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

This module provides a list of known mime-types, combined from various sources. For instance, it contains all IANA types and the knowledge of Apache.

This module exposes interpreter threads to the Perl level.

This is a Moose role which provides an alternate constructor for creating objects using parameters passed in from the command line.

Template::Tiny is a reimplementation of a subset of the functionality from Template Toolkit in as few lines of code as possible.

It is intended for use in light-usage, low-memory, or low-cpu templating situations, where you may need to upgrade to the full feature set in the future, or if you want the retain the familiarity of TT-style templates.

Devel::CheckLib is a Perl module that checks whether a particular C library and its headers are available. You can also check for the presence of particular functions in a library, or even that those functions return particular results.
