NAME
Catalyst::Manual::Components - Reuseable components for Catalyst applications
DESCRIPTION
This section lists the some of the components (and plugins) that are available to extend the runtime functionality of Catalyst. Most components are not distributed with Catalyst but should be available from CPAN. They typically require additional modules from CPAN.
This list may well be outdated by the time you read this, and some plugins may be deprecated, or, conversely, may now part of core Catalyst. Be sure to check the Catalyst:: and CatalystX:: namespaces for additional components, and consult the mailing list ( http://dev.catalyst.perl.org/wiki/Support ) for advice on the current status or preferred use of your chosen plugin/framework.
PLUGINS
Take care with plugins! In general with a plugin ask "should this be acting globally on my application application?". If not it should be a Controller Role (e.g. see Catalyst::TraitFor::Controller::reCAPTCHA.
Catalyst::Plugin::Account::AutoDiscovery
Provides Account Auto-Discovery for Catalyst.
Catalyst::Plugin::Acme::Scramble
Implements a demonstration showing how easily fluent speakers can read scrambled text if the first and last letters remain constant but the middle . Operates on text/plain and text/html served by your Catalyst application. This should really be a controller role, or even a View these days.
Catalyst::Plugin::Alarm
Catalyst::Plugin::AtomPP
Allows you to dispatch AtomPP methods.
Catalyst::Plugin::AtomServer
A plugin that implements the necessary bits to make it easy to build an Atom API server for any Catalyst-based application.
Catalyst::Plugin::Authentication
An infrastructure plugin for the Catalyst authentication framework. Now the recommended way to do any form of Authentication.
Note that newer versions of the authentication plugin allow multiple realms, so that you can authenticate users in different ways in different parts of your application.
This, however, has involved deprecated all classes in the Catalyst::Plugin::Authentication::Credential::XXX and Catalyst::Plugin::Authentication::Store::XXX namespaces.
These plugins are still usable, but they have mostly been replaced with new modules in the new namespace which will work together.
Available Credential modules:
Catalyst::Authentication::Credential::AuthTkt
Allows you to use the Apache::AuthTkt module with Catalyst.
Catalyst::Authentication::Credential::FBConnect
Allows you to authenticate Facebook users using the FBConnect API.
Catalyst::Authentication::Credential::Flickr
Provides authentication via Flickr, using its API.
Catalyst::Authentication::Credential::HTTP
Allows you to authenticate users using HTTP Basic or Digest authentication.
Catalyst::Authentication::Credential::HTTP::Proxy
Allows you to authenticate users against a remote web server offering HTTP authentication.
Catalyst::Authentication::Credential::Kerberos
Allows you to authenticate your users against a Kerberos server.
Catalyst::Authentication::Credential::OAuth
Allows you to authenticate users using their login on other websites supporting the OAuth protocol.
Catalyst::Authentication::Credential::OpenID
Allows you to authenticate users using their login on other websites supporting the OpenID protocol.
Catalyst::Authentication::Credential::Password
Takes a username (or userid) and a password, and tries various methods of comparing a password based on what the chosen store's user objects support. Part of the Authentication Framework Catalyst::Plugin::Authentication.
Catalyst::Authentication::Credential::RPX
Allows you to authenticate users using the RPX protocol.
Catalyst::Authentication::Credential::Remote
Allows you to authenticate users in Catalyst that have already been authenticated by your web server. This is useful for authenticating users with SSL Client certificates, and using NTLM or any other authentication protocol natively supported by your web server.
Catalyst::Authentication::Credential::Testing
Allows you to set the same password for all users, which is useful when you want to test logging in as multiple users or multiple types of user, without having to mock things, or set all users' passwords in your test suite.
Catalyst::Authentication::Credential::Authen::Simple
Allows any of the Authen::Simple family of modules to be used to authenticate users in Catalyst.
Available Store modules:
Catalyst::Authentication::Store::DBIx::Class
Does authentication and authorization against a DBIx::Class model.

Catalyst::Authentication::Store::DBI
Allows you to use a plain DBI database connection to identify users.
Catalyst::Authentication::Store::Htpasswd

The Null store is a transparent store where any supplied user data is accepted. This is mainly useful for remotely authenticating credentials (e.g. OpenID) which may not be tied to any local storage.
Catalyst::Authentication::Store::RDBO
Allows access to authentication information stored in a database via a Rose::DB::Object class.
Catalyst::Authentication::Store::Tangram
Allows access to authentication information stored in a database via a Tangram class.

Catalyst::Authentication::Store::Jifty::DBI
Allows access to authentication information stored in a database via a Jifty::DBI class.
Catalyst::Authentication::User::Hash

A plugin to allow subrequests to actions to be made within Catalyst. Nice for portal software and such.
Catalyst::Plugin::SuperForm
An interface to the HTML::SuperForm module, enabling easy HTML form creation.
Catalyst::Plugin::Unicode::Encoding
Provides a Unicode-aware Catalyst. On request, it decodes all params from UTF-8 octets into a sequence of logical characters. On response, it encodes the body into UTF-8 octets.
Catalyst::Plugin::Unicode
Disrecommended plugin which tries to autodetect the uft8ness of the output and do the correct thing. This may work in some cases, but if it helps, you've already painted yourself into a corner - try to avoid!
Catalyst::Plugin::Upload::Basename
Catalyst::Plugin::Upload::MD5
Computes the MD5 message digest of uploaded files.
Catalyst::Plugin::Upload::MIME
Catalyst::Plugin::UploadProgress
