Class::Spiffy is a framework and methodology for doing object oriented (OO) programming in Perl. Class::Spiffy combines the best parts of Exporter.pm, base.pm, mixin.pm and SUPER.pm into one magic foundation class. It attempts to fix all the nits and warts of traditional Perl OO, in a clean, straightforward and (perhaps someday) standard way.

Class::Tangram is a common base class originally intended for use with Tangram objects, that gives you free constructors, access methods, update methods, and a destructor that should help in breaking circular references for you. Type checking is achieved by parsing the Tangram schema for the object, which is contained within the object class in an exported variable $schema.

The Config::Objective module provides a mechanism for parsing config files to manipulate configuration data. Unlike most other config file modules, which represent config data as simple variables, Config::Objective represents config data as perl objects. This allows for a much more flexible configuration language, since new classes can be easily written to add methods to the config syntax.

Config::Versioned allows an application to access configuration parameters not only by parameter name, but also by version number. This allows for the configuration subsystem to store previous versions of the configuration parameters. When requesting the value for a specific attribute, the programmer specifies whether to fetch the most recent value or a previous value.

Curses::Application is designed to provide a flexible framework for rapid application development of Curses-based console applications in Perl. Based on Curses::Widgets and Curses::Forms, Curses::Application provides a flexible OO framework to manage forms, widgets, and dialogs, without (hopefully) ever having to deal directly with Curses calls.

Curses::Forms is designed to provide high level APIs for rapid user interface design on the console in Perl. Based on Curses::Widgets, Curses::Forms provide a flexible OO framework to manage a collection of widgets on forms and dialogs. While intended to be used in the Curses::Application framework, it can also be used alone with Curses::Widgets for quick and dirty interfaces.

Dump in hexadecimal the content of a scalar. The result is returned in a string. Each line of the result consists of the offset in the source in the leftmost column of each line, followed by one or more columns of data from the source in hexadecimal. The rightmost column of each line shows the printable characters (all others are shown as single dots).

This module is about the native integer numerical data type. A native integer is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native integer type. There are actually two native integer representations: signed and unsigned. Both are handled by this module.

Anjuta is a very versatile Integrated development environment for C and C++. Written in GTK/GNOME and written for GTK+/GNOME, it features many advanced programming tools and utilities. It is basically a GUI interface for the bunch of command line programming utilities and tools available for FreeBSD, which are usually run in console and are very user unfriendly.

Data::Alias is a module that allows you to apply "aliasing semantics" to a section of code, causing aliases to be made wherever Perl would normally make copies instead. You can use this to improve efficiency and readability, when compared to using references.
