Storable brings persistence to your Perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time.

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.

List::SomeUtils provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.

All of the below functions are implementable in only a couple of lines of Perl code. Using the functions from this module however should give slightly better performance as everything is implemented in C. The pure-Perl implementation of these functions only serves as a fallback in case the C portions of this module couldn't be compiled on this machine.

Data::Entropy provides modules relating to the generation and use of entropy. The Data::Entropy::Source class manages the entropy coming from a particular source. This class acts as a layer over a raw entropy source, which may be a normal I/O handle or a special-purpose class. The Data::Entropy::RawSource::* classes provide fundamental sources of entropy. The sources specially supported are an OS-supplied entropy collector, downloads from servers on the Internet, and cryptographic fake entropy. The Data::Entropy::Algorithms module contains a collection of fundamental algorithms that use entropy. There are random number generators and functions to shuffle arrays.

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.

Meta::Builder is designed to be a generic tool for writing Meta objects. Unlike specialized tools, Meta::Builder makes no assumptions about what metrics you will care about. Meta::Builder also makes it simple for others to extend your meta-object based tools by providing hooks for other packages to add metrics to your meta object.

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

This module provides a collection of named blocks that allow a return statement to return different values depending on the context in which it is called.

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 Log::Any adapter to send log messages to screen, with colors and some other features.

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.

The Digest::MD5 module allows you to use the MD5 Message Digest algorithm from within Perl programs. The algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input.

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

Internationalized Domain Names (IDNs) use characters drawn from a large repertoire (Unicode), but IDNA allows the non-ASCII characters to be represented using only the ASCII characters already allowed in so-called host names today (letter-digit-hyphen, /[A-Z0-9-]/i).

Use this module if you just want to convert domain names (or email addresses), using whatever IDNA standard is the best choice at the moment.

This module tries to make install path resolution as easy as possible.

This module provides some XS functions to assist in writing parsers for sub-like syntax, primarily for authors of keyword plugins using the PL_keyword_plugin hook mechanism.

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

Exporter::Tiny supports many of Sub::Exporter's external-facing features including renaming imported functions with the `-as`, `-prefix` and `-suffix` options; explicit destinations with the `into` option; and alternative installers with the `installer` option. But it's written in only about 40% as many lines of code and with zero non-core dependencies.

The functions exported by this module allow you to open URLs in the user's browser. A set of known commands per OS-name is tested for presence, and the first one found is executed. With an optional parameter, all known commands are checked.

XML::Writer is a simple Perl module for writing XML documents: it takes care of constructing markup and escaping data correctly. By default, it also performs a significant amount of well-formedness checking on the output to make certain (for example) that start and end tags match, that there is exactly one document element, and that there are not duplicate attribute names.

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

Devel::StackTrace::AsHTML adds as_html method to Devel::StackTrace which displays the stack trace in beautiful HTML, with code snippet context and function parameters. If you call it on an instance of Devel::StackTrace::WithLexicals, you even get to see the lexical variables of each stack frame.

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.

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.
