PPIx::Utils is a collection of utility functions for working with PPI documents. The functions are organized into submodules, and may be imported from the appropriate submodules or via this module.

Assigns a new name to referenced sub. If package specification is omitted in the name, then the current package is used. The return value is the sub.

Sometimes you need to test what happens when a given module is not installed. This module provides a way of temporarily hiding installed modules from perl's require mechanism. The Module::Mask object adds itself to @INC and blocks require calls to restricted modules.

This module provides various type-testing functions. These are intended for functions that care what type of data they are operating on. There are two flavours of function. Functions of the first flavour provide type classification only. Functions of the second flavour also check that an argument is of an expected type. The type enforcement functions handle only the simplest requirements for arguments of the types handled by the classification functions. Enforcement of more complex types may be built using the classification functions, or it may be more convenient to use a module designed for the more complex job, such as Params::Validate

Config::INI is a module that facilates the reading and writing of .ini-style configuration files.

This module implements an interface to the Linux 2.6.13 and later Inotify file change notification system.

Path::Iterator::Rule iterates over files and directories to identify ones matching a user-defined set of rules. The API is based heavily on File::Find::Rule, but with more explicit distinction between matching rules and options that influence how directories are searched. A Path::Iterator::Rule object is a collection of rules (match criteria) with methods to add additional criteria. Options that control directory traversal are given as arguments to the method that generates an iterator.

A summary of features for comparison to other file finding modules:

• provides many helper methods for specifying rules

• offers (lazy) iterator and flattened list interfaces

• custom rules implemented with callbacks

• breadth-first (default) or pre- or post-order depth-first searching

• follows symlinks (by default, but can be disabled)

• directories visited only once (no infinite loop; can be disabled)

• doesn't chdir during operation

• provides an API for extensions

As a convenience, the PIR module is an empty subclass of this one that is less arduous to type for one-liners.

This module provides a clone() method which makes recursive copies of nested hash, array, scalar and reference types, including tied variables and objects.

This Spreadsheet::ParseExcel module parses Microsoft Excel95, 97 and 2000 format files.

File::Find::Rule::Perl provides methods for finding various types Perl-related files, or replicating search queries run on a distribution in various parts of the CPAN ecosystem.

Lingua::Translit can be used to convert text from one writing system to another, based on national or international transliteration tables. Where possible a reverse transliteration is supported.

Data::Dump::Streamer provides ways to accurately serialize a data structure as Perl code.

This module provides functions for expressing durations in rounded or exact terms.

This module provides a general-purpose date and datetime type for perl.

perlcritic is a Perl source code analyzer. It is the executable front-end to the Perl::Critic engine, which attempts to identify awkward, hard to read, error-prone, or unconventional constructs in your code. Most of the rules are based on Damian Conway's book "Perl Best Practices". However, perlcritic is not limited to enforcing PBP, and it will even support rules that contradict Conway. All rules can easily be configured or disabled to your liking.

XSLoader module defines a standard simplified interface to the dynamic linking mechanisms available on many platforms. Its primary purpose is to implement cheap automatic dynamic loading of Perl modules.

This is pragma to change Perl 5's standard method resolution order from depth-first left-to-right (a.k.a - pre-order) to the more sophisticated C3 method resolution order.

Authen::DecHpwd implements the SYS$HASH_PASSWORD password hashing function from VMS (also known as LGI$HPWD) and some associated VMS username and password handling functions. The password hashing function is implemented in XS with a pure Perl backup version for systems that cannot handle XS.

This toolkit primarily provides modules for performing both traditional and object-oriented i/o) on things *other* than normal filehandles; in particular, IO::Scalar, IO::ScalarArray, and IO::Lines.

Guard implements so-called guards. A guard is something (usually an object) that "guards" a resource, ensuring that it is cleaned up when expected.

Specifically, this module supports two different types of guards: guard objects, which execute a given code block when destroyed, and scoped guards, which are tied to the scope exit.

Growl::GNTP is a Perl implementation of the client part of the Growl Notification Transport Protocol (GNTP).

This module provides some XS functions to assist in writing syntax modules that provide new perl-visible syntax, primarily for authors of keyword plugins using the PL_keyword_plugin hook mechanism.

Devel::LexAlias provides the ability to alias a lexical variable in a subroutines scope to one of your choosing.

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).
