Hash::FieldHash provides the field hash mechanism which supports the inside-out technique. It is an alternative to Hash::Util::FieldHash with a simpler interface, higher performance, and relic support.

This module does not provide any methods. Simply loading it changes the default naming policy for the loading class so that accessors are separated into get and set methods. The get methods have the same name as the accessor, while set methods are prefixed with "_set_".

Locale::gettext provides an object oriented interface to the internationalization functions provided by the C library.

This class lets you build groups of accessors that will call different getters and setters.

This class provides several methods for host name resolution. It is designed to be used with event loops. Names are resolved by your system's native getaddrinfo(3) implementation, called in a separate thread to avoid blocking the entire application. Threading overhead is limited by using system threads instead of Perl threads.

Role::Tiny is a minimalist role composition tool.

This module is optionally used by Type::Tiny to provide faster, C-based implementations of some type constraints. This package has only core dependencies, and does not depend on Type::Tiny, so other data validation frameworks might also consider using it.

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 Perl module provides Unicode normalization forms.

RFCs 2822 and 822 specify date formats to be used by email. This module parses and emits such dates.

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

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

File::Find::Object::Rule is an alternative Perl interface to File::Find::Object.

App::cpanminus is a script to get, unpack, build and install modules from CPAN and does nothing else. It's dependency free (can bootstrap itself), requires zero configuration, and stands alone. When running, it requires only 10MB of RAM.

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.

List::SomeUtils::XS is a XS implementation for List::SomeUtils. There are no user-facing parts here. See List::SomeUtils for API details.

This module provides convenience methods that let you easily create DateTime::Set objects for various recurrences, such as "once a month" or "every day". You can also create more complicated recurrences, such as "every Monday, Wednesday and Thursday at 10:00 AM and 2:00 PM".

This module provides a small, fast utility for working with file paths.

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

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.

Date::Manip is a series of modules for common date/time operations, such as comparing two times, determining a date a given amount of time from another, or parsing international times.

Parse::CPAN::Meta is a parser for META.json and META.yml files, using JSON::PP and/or CPAN::Meta::YAML.

This package provides a selection of regular expression subroutines including is_regexp, regexp_seen_evals, regexp_is_foreign, regexp_is_anchored, serialize_regexp, and deserialize_regexp.

Data::UUID provides a framework for generating Universally Unique Identifiers (UUIDs), also known as Globally Unique Identifiers (GUIDs). A UUID is 128 bits long, and is guaranteed to be different from all other UUIDs/GUIDs generated until 3400 CE.
