Catalyst (software)
Catalyst is an open-source web application framework written in Perl. It closely follows the model–view–controller (MVC) architecture and supports a number of experimental web patterns. It is written using Moose, a modern object system for Perl. Its design is heavily inspired by frameworks such as Ruby on Rails, Maypole, and Spring.
Catalyst can be used by web application developers to deal with code common to all web applications. It provides an interface for receiving page requests, dispatching page requests into developer-written code to process, and return of the requests. Catalyst also provides a standardised interface for data models, authentication, session management and other common web application elements.
All of these elements are implemented as plugins to a set of common interfaces, allowing the developer to change the specific method used (e.g. a session storing in shared memory versus as a database table, or using FastCGI versus operating as an within Apache's mod_perl) by changing the configuration of Catalyst to use a different plugin without altering the application code.
Catalyst is primarily distributed through the CPAN, which is the official distribution channel for Perl libraries and applications.
Maypole was one of the first web application frameworks for the Perl programming language that was based on the MVC pattern; its principal author was Simon Cozens. Catalyst started as a fork of Maypole, intended to become Maypole 3.0. Development ceased on Maypole, however, with its most recent release in April 2008, and Catalyst became its modern supported equivalent.
The first development release of Catalyst took place on 28 January 2005. The first official version was published on CPAN on 16 February 2005. As of June 2011, Catalyst had 201 registered contributors.
Catalyst is based on the "don't repeat yourself" (DRY) principle, which means that definitions should only have to be made once. Catalyst can be used with automatic class loading from the database through one of the many loader modules, thus requiring no code for the database layer. But, if you require the flexibility of manually doing everything, it's also an option. Another guiding principle of Catalyst is flexibility.
Catalyst promotes the re-use of existing Perl modules that already handle common web application concerns well.
