Jifty - an application framework

 # Object containing lots of web related goodies...
 my $web      = Jifty->web;
 my $request  = Jifty->web->request;
 my $response = Jifty->web->response;
 my $link     = Jifty->web->link( label => _('W00t'), url => '/whatsit' );
 # Retrieve information from your application's etc/config.yml file.
 my $config   = Jifty->config;
 # Retrieve the Jifty::DBI handle
 my $handle   = Jifty->handle;
 # Load an application class, very handy in plugins
 my $class    = Jifty->app_class('Model', 'Foo');
 my $foo      = $class->new;
 $foo->create( frobnicate => 42 );
 # Configure information related to your application's actions
 my $api      = Jifty->api;
 # Retrieve general information about Mason
 my $handler  = Jifty->handler;

Yet another web framework.

DRY (Don't Repeat Yourself)
Jifty tries not to make you say things more than once.
Out of the proverbial box, Jifty comes with one way to do everything you should need to do: One database mapper, one templating system, one web services layer, one AJAX toolkit, one set of handlers for standalone or FastCGI servers. We work hard to make all the bits play well together, so you don't have to.
With Jifty, it's easy to let the user go off and do something else, like fill out a wizard, look something up in the help system or go twiddle their preferences and come right back to where they were.
Form-based dispatch
This is one of the things that Jifty does that we've not seen anywhere else. Jifty owns your form rendering and processing. This means you never need to write form handling logic. All you say is "I want an input for this argument here" and Jifty takes care of the rest. (Even autocomplete and validation)
A Pony
Jifty is the only web application framework that comes with a pony.

If this is your first time using Jifty, Jifty::Manual::Tutorial is probably a better place to start.

This class method instantiates a new "Jifty" object. This object deals with configuration files, logging and database handles for the system. Before this method returns, it calls the application's "start" method (i.e. "MyApp->start") to handle any application-specific startup.
Most of the time, the server will call this for you to set up your "Jifty" object. If you are writing command-line programs that want to use your libraries (as opposed to web services) you will need to call this yourself.
See Jifty::Config for details on how to configure your Jifty application.
If this is set to true, Jifty will not create a Jifty::Handle and connect to a database. Only use this if you're about to drop the database or do something extreme like that; most of Jifty expects the handle to exist. Defaults to false.
The name that Jifty::Logger will log under. If you don't specify anything Jifty::Logger will log under the empty string. See Jifty::Logger for more information.

An accessor for the Jifty::Config object that stores the configuration for the Jifty application.

An accessor for our Jifty::Logger object for the application.
You probably aren't interested in this. See "log" for information on how to make log messages.

An accessor for our Jifty::Handler object.
This is another method that you usually don't want to mess with too much. Most of the interesting web bits are handled by "web".

An accessor for the Jifty::Handle object that stores the database handle for the application.

An accessor for the Jifty::API object that publishes and controls information about the application's Jifty::Actions.

Return Class in application space. For example "app_class('Model', 'Foo')" returns YourApp::Model::Foo.
By the time you get it back, the class will have already been required
Is you pass a hashref as the first argument, it will be treated as configuration parameters. The only existing parameter is "require", which defaults to true.

An accessor for the Jifty::Web object that the web interface uses.

Returns a list of Jifty::Plugin objects for this Jifty application.

Find plugins by name.

An accessor for the Jifty::ClassLoader object that stores the loaded classes for the application.

Set up our database connection. Optionally takes a paramhash with a single argument. This method is automatically called by "new".
Defaults to false. If true, Jifty won't try to set up a database handle
Defaults to false. If true, plugins are notified that this is a pre-init, any trigger registration in "init()" should not happen during this stage. Note that model mixins' "register_triggers" is unrelated to this.
If "no_handle" is set or our application's config file is missing a "Database" configuration
section or has a "SkipDatabase: 1" directive in its framework configuration, does nothing.

Returns a globally unique id for this instance of this jifty application. This value is generated the first time it's accessed

Forks a background process, and ensures that database connections and sockets are not shared with the parent process.

Returns true if the application is in admin mode. This should be used instead of "Jifty->config->framework('AdminMode')".
