This module provide functions that takes a list of values as their argument and produces a string as its result. The string contains Perl code that, when "eval"ed, produces a deep copy of the original arguments.

This package provides procedures to create read-only scalars, arrays, and hashes.

Log::Log4perl lets you remote-control and fine-tune the logging behaviour of your system from the outside. It implements the widely popular (Java-based) Log4j logging package in pure Perl.

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.

Pod::Simple is a Perl library for parsing text in the Pod (plain old documentation) markup language that is typically used for writing documentation for Perl and for Perl modules.

Term::Encoding is a simple module to detect the encoding of the current terminal expects in various ways.

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.

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 Perl module provides Chinese encodings that are not part of Perl by default, including "BIG5-1984", "BIG5-2003", "BIG5PLUS", "BIG5EXT", "CCCII", "EUC-TW", "CNS11643-*", "GB18030", and "UNISYS".

The Cache modules are designed to assist a developer in persisting data for a specified period of time. Often these modules are used in web applications to store data locally to save repeated and redundant expensive calls to remote machines or databases. People have also been known to use Cache::Cache for its straightforward interface in sharing data between runs of an application or invocations of a CGI-style script or simply as an easy to use abstraction of the file system or shared memory.

Text::CSV provides facilities for the composition and decomposition of comma-separated values. An instance of the Text::CSV class can combine fields into a CSV string and parse a CSV string into fields.

The File::LibMagic module is a simple perl interface to libmagic from the file package.

Conf::Libconfig is a Perl interface to the libconfig configuration file library. It support scalar, array, and hash data structures just like its C/C++ counterpart. It reduces the effort required to implement a configuration file parser in your Perl programme and allows sharing configuration files between languages.

This module is intended to easily load initialization values for attributes on object construction from an appropriate config file. The building is done in MooX::ConfigFromFile::Role---using MooX::ConfigFromFile ensures that the role is applied.

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.

The functions exported by this module deal with runtime handling of Perl modules, which are normally handled at compile time.

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.

IO::Pager can be used to locate an available pager and use it to display output if a TTY is in use.

Term::ProgressBar provides a simple progress bar on the terminal, to let the user know that something is happening, roughly how much stuff has been done, and maybe an estimate at how long remains.

Term::ProgressBar is a wonderful module for showing progress bars on the terminal. This module acts very much like that module when it is run interactively. However, when it is not run interactively (for example, as a cron job) then it does not show the progress bar.

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

Class:Unload unloads a given class by clearing out its symbol table and removing it from %INC.

The File::List module crawls the directory tree starting at the provided base directory and can return files (and/or directories if desired) matching a regular expression.

This module provides conflicts checking for Module::Runtime, which had a recent release that broke some versions of Moose. It is called from Moose::Conflicts and moose-outdated.
