This package provides a selection of regular expression subroutines including is_regexp, regexp_seen_evals, regexp_is_foreign, regexp_is_anchored, serialize_regexp, and deserialize_regexp.

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.

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

This package provides a way to memory map a file.

This module provides syntactical support for try/catch control flows.

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.

This module opens a config file and parses its contents for you. The format of config files supported by Config::General is inspired by the well known Apache config format and is 100% compatible with Apache configs, but you can also just use simple name/value pairs in your config files. In addition to the capabilities of an Apache config file it supports some enhancements such as here-documents, C-style comments, and multiline options.

Log::Report combines three tasks which are closely related in one: logging, exceptions, and translations.

Moo is an extremely light-weight Object Orientation system. It allows one to concisely define objects and roles with a convenient syntax that avoids the details of Perl's object system. Moo contains a subset of Moose and is optimised for rapid startup.

Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.

This module provides functions for fast reading and writing of files.

This module provides a mechanism for determining if the pod for a given module is comprehensive.

This module, ReadKey, provides ioctl control for terminals so the input modes can be changed (thus allowing reads of a single character at a time), and also provides non-blocking reads of stdin, as well as several other terminal related features, including retrieval/modification of the screen size, and retrieval/modification of the control characters.

File::Temp can be used to create and open temporary files in a safe way.

Safe::Hole can execute outside defined subroutines in the original main compartment from the Safe compartment.

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

This module provides tools to deal with International Standard Music Numbers.

This package lets you declare types using short names, but behind the scenes it namespaces all your type declarations, effectively prevent name clashes between packages.

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.

String::Format lets you define arbitrary printf-like format sequences to be expanded. This module would be most useful in configuration files and reporting tools, where the results of a query need to be formatted in a particular way. It was inspired by mutt's .

A shared memory cache through an mmap'ed file. It's core is written in C for performance. It uses fcntl locking to ensure multiple processes can safely access the cache at the same time. It uses a basic LRU algorithm to keep the most used entries in the cache.

This module provides two new keywords, fun and method, for defining functions and methods with parameter lists. At minimum this saves you from having to unpack @_ manually, but this module can do much more.

Text::Sprintf::Named provides a sprintf equivalent with named conversions. Named conversions are sprintf field specifiers (like %s or %4d) only they are associated with the key of an associative array of parameters. So for example %(name)s will emit the name parameter as a string, and %(num)4d will emit the num parameter as a variable with a width of 4.

ExtUtils::PkgConfig is a very simplistic interface to the pkg-config utility, intended for use in the Makefile.PL of perl extensions which bind libraries that pkg-config knows. It is really just boilerplate code that you would have written yourself.
