DateTimeX::Easy uses a variety of DateTime::Format packages to create DateTime objects, with some custom tweaks to smooth out the rough edges (mainly concerning timezone detection and selection).

XString provides the B string helpers in one isolated package. Right now only cstring and perlstring are available.

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.

Object::Signature is an abstract base class that you can inherit from in order to allow your objects to generate unique cryptographic signatures.

Create a command line tool with your Mo, Moo, Moose objects. You have an option keyword to replace the usual has to explicitly use your attribute on the command line. The option keyword takes additional parameters and uses Getopt::Long::Descriptive to generate a command line tool.

Path::Class is a module for manipulation of file and directory specifications in a cross-platform manner.

This module provides an interface to layout and image generation of directed and undirected graphs in a variety of formats (PostScript, PNG, etc.) using the dot, neato, twopi, circo, and fdp programs from the Graphviz project. This package is deprecated in favour of GraphViz2.

When an undefined variable is dereferenced, it gets silently upgraded to an array or hash reference (depending of the type of the dereferencing). This behaviour is called autovivification and usually does what you mean but it may be unnatural or surprising because your variables get populated behind your back. This is especially true when several levels of dereferencing are involved, in which case all levels are vivified up to the last, or when it happens in intuitively read-only constructs like exists. The pragma provided by this package lets you disable autovivification for some constructs and optionally throws a warning or an error when it would have happened.

This is a unified interface to retrieve terminal size. It loads one module of a list of known alternatives, each implementing some way to get the desired terminal information. This loaded module will actually do the job on behalf of Term::Size::Any.

When subclassing a class, you may occasionally want to dispatch control to the superclass---at least conditionally and temporarily. This module provides nicer equivalents to the native Perl syntax for calling superclasses, along with a universal super method to determine a class' own superclass, and better support for run-time mix-ins and roles.

Text::Unidecode provides a function, unidecode(...) that takes Unicode data and tries to represent it in US-ASCII characters (i.e., the universally displayable characters between 0x00 and 0x7F). The representation is almost always an attempt at transliteration-- i.e., conveying, in Roman letters, the pronunciation expressed by the text in some other writing system.

Like Tcl's uplevel() function, but not quite so dangerous. The idea is just to fool caller(). All the really naughty bits of Tcl's uplevel() are avoided.

File::pushd does a temporary chdir that is easily and automatically reverted, similar to pushd in some Unix command shells. It works by creating an object that caches the original working directory. When the object is destroyed, the destructor calls chdir to revert to the original working directory. By storing the object in a lexical variable with a limited scope, this happens automatically at the end of the scope.

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

Class::Data::Inheritable is for creating accessor/mutators to class data. That is, if you want to store something about your class as a whole (instead of about a single object). This data is then inherited by your subclasses and can be overridden.

Lexical::SealRequireHints prevents leakage of lexical hints

Number::Range is an object-oriented interface to test if a number exists in a given range, and to be able to manipulate the range.

This module allows you to specify conflicting versions of modules separately and deal with them after the module is done installing.

POSIX::strftime::Compiler provides GNU C library compatible strftime(3). But this module is not affected by the system locale. This feature is useful when you want to write loggers, servers, and portable applications.

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

Time::Duration::Parse is a module to parse human readable duration strings like "2 minutes" and "3 seconds" to seconds.

This module reads a file backwards line by line. It is simple to use, memory efficient and fast. It supports both an object and a tied handle interface.

It is intended for processing log and other similar text files which typically have their newest entries appended to them. By default files are assumed to be plain text and have a line ending appropriate to the OS. But you can set the input record separator string on a per file basis.

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.

This module provides $CWD and @CWD as alternatives to chdir().
