This module generalises the mechanism of the wantarray function, allowing a function to determine in some detail how its return value is going to be immediately used.

This module simply interpolates option file hints in @ARGV by the contents of the pointed files. This enables option reading from files instead of or additional to the usual reading from the command line.

Dates are complex enough without times and timezones. This module may be used to create simple date objects. It handles validation, interval arithmetic, and day-of-week calculation. It does not deal with hours, minutes, seconds, and time zones.

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

The PPI module parses, analyzes and manipulates Perl code.

This package compiles yacc-like Look Ahead LR (LALR) grammars to generate Perl object oriented parser modules.

Loading MooX::StrictConstructor makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it dies.

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

Text::Patch combines source text with given diff (difference) data. Diff data is produced by Text::Diff module or by the standard diff utility.

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

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.

This module provides a convenient way to perform cleanup or other forms of resource management at the end of a scope. It is particularly useful when dealing with exceptions: the Scope::Guard constructor takes a reference to a subroutine that is guaranteed to be called even if the thread of execution is aborted prematurely. This effectively allows lexically-scoped "promises" to be made that are automatically honoured by perl's garbage collector.

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.

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".

BinHex is a format for transporting files safely through electronic mail, as short-lined, 7-bit, semi-compressed data streams. This module provides a means of converting those data streams back into into binary data.

The Readonly module is an effective way to create non-modifiable variables. However, it's relatively slow.

The reason it's slow is that is implements the read-only-ness of variables via tied objects. This mechanism is inherently slow. Perl simply has to do a lot of work under the hood to make tied variables work.

This module corrects the speed problem, at least with respect to scalar variables. When Readonly::XS is installed, Readonly uses it to access the internals of scalar variables. Instead of creating a scalar variable object and tying it, Readonly simply flips the SvREADONLY bit in the scalar's FLAGS structure.

This module makes the functionality of the perltidy command available to Perl scripts. Any or all of the input parameters may be omitted, in which case the @ARGV array will be used to provide input parameters as described in the perltidy(1) man page.

DateTime::Format::Builder creates DateTime parsers. Many string formats of dates and times are simple and just require a basic regular expression to extract the relevant information. Builder provides a simple way to do this without writing reams of structural code.

This library allows communication with a smart card using PC/SC from a Perl script.

Mail::Sendmail is a pure perl module that provides a simple means to send email from a perl script. The module only requires Perl5 and a network connection.

SVG is a Perl module which generates a nested data structure containing the DOM representation of an SVG (Scalable Vector Graphics) image. Using SVG, you can generate SVG objects, embed other SVG instances into it, access the DOM object, create and access Javascript, and generate SMIL animation content.

This module provide a convenient way to create directories of arbitrary depth and to delete an entire directory subtree from the file system.

This module understands the formats used by MySQL for its DATE, DATETIME, TIME, and TIMESTAMP data types. It can be used to parse these formats in order to create DateTime objects, and it can take a DateTime object and produce a string representing it in the MySQL format.

Given a list of scalars or reference variables, Data::Dumper writes out their contents in Perl syntax. The references can also be objects. The content of each variable is output in a single Perl statement. It handles self-referential structures correctly.
