This Perl module provides Unicode normalization forms.

One recurring problem in modules that use Scalar::Util's weaken function is that it is not present in the pure-perl variant. If Scalar::Util is not available at all, it will issue a normal dependency on the module. However, if Scalar::Util is relatively new ( it is >= 1.19 ) and the module does not have weaken, the install will bail out altogether with a long error encouraging the user to seek support.

This module brings the speed advantages of Set::IntSpan (written by Steven McDougall) to arrays. Uses include manipulating grades, routing tables, or any other situation where you have mutually exclusive ranges of integers that map to given values.

Perl module for using special zip files (called Perl ARchives) as libraries from which Perl modules can be loaded.

This module uses Pod::Simple to convert POD to Markdown.

This module provides a file handle that hides the beginning of a file, by modifying the seek() and tell() calls.

This is a meta-package containing specifications for installing all the Test::Run plugins.

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.

Similar to List::MoreUtils, Hash::MoreUtils contains trivial but commonly-used functionality for hashes. The primary focus for the moment is providing a common API - speeding up by XS is far away at the moment.

This module is for manipulating data as hierarchical tag/value pairs (Structured TAGs or Simple Tree AGgregates). These datastructures can be represented as nested arrays, which have the advantage of being native to Perl.

Xslate is a template engine, tuned for persistent applications, safe as an HTML generator, and with rich features. The core design principle is that template logic does not have access outside the template without permission.

This package consists of a Perl module for date calculations based on the Gregorian calendar, thereby complying with all relevant norms and standards: ISO/R 2015-1971, DIN 1355 and, to some extent, ISO 8601 (where applicable).

Chaolin Zhang's Perl Library (czplib) contains assorted functions and data structures for processing and analysing genomic and bioinformatics data.

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

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.

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

This module provides functions for fast reading and writing of files.

Routines to manipulate defhash, a convention to define things more precisely and uniformly using a hash, in Perl.

Magic is Perl's way of enhancing variables. This mechanism lets the user add extra data to any variable and hook syntactical operations (such as access, assignment or destruction) that can be applied to it. With this module, you can add your own magic to any variable without having to write a single line of XS.

Bit::Vector is an efficient C library which allows you to handle bit vectors, sets (of integers), "big integer arithmetic" and boolean matrices, all of arbitrary sizes. The package also includes an object-oriented Perl module for accessing the C library from Perl, and optionally features overloaded operators for maximum ease of use. The C library can nevertheless be used stand-alone, without Perl.

This module provides three utility subroutines that make it easier to develop interactive applications: is_interactive(), interactive(), and busy().

ExtUtils::PkgConfig is a very simplistic interface to the pkg-config utility, intended for use in the Makefile.PL of perl extensions which bind libraries that pkg-config knows. It is really just boilerplate code that you would have written yourself.

This package provides an ASCII mapping for the eucJP encoding.

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