DESCRIPTION

Catalyst is based upon Maypole, which you should consider for smaller projects.

The key concept of Catalyst is DRY (Don't Repeat Yourself).

See Catalyst::Manual for more documentation.

Catalyst plugins can be loaded by naming them as arguments to the "use Catalyst" statement. Omit the Catalyst::Plugin:: prefix from the plugin name, so Catalyst::Plugin::My::Module becomes My::Module.

    use Catalyst 'My::Module';

Special flags like -Debug and -Engine can also be specifed as arguments when Catalyst is loaded:

    use Catalyst qw/-Debug My::Module/;

The position of plugins and flags in the chain is important, because they are loaded in exactly the order that they appear.

The following flags are supported:

-Debug

enables debug output, i.e.:

    use Catalyst '-Debug';

this is equivalent to:

    use Catalyst;
    sub debug { 1 }

-Engine

Force Catalyst to use a specific engine. Omit the Catalyst::Engine:: prefix of the engine name, i.e.:

    use Catalyst '-Engine=CGI';

METHODS

debug

Overload to enable debug messages.

config

Returns a hashref containing your applications settings.

$c->engine

Contains the engine class.

$c->log

Contains the logging object. Unless it is already set Catalyst sets this up with a Catalyst::Log object. To use your own log class:

    $c->log( MyLogger->new );
    $c->log->info("now logging with my own logger!");

Your log class should implement the methods described in the Catalyst::Log man page.

$c->plugin( $name, $class, @args )

Instant plugins for Catalyst. Classdata accessor/mutator will be created, class loaded and instantiated.

    MyApp->plugin( 'prototype', 'HTML::Prototype' );

    $c->prototype->define_javascript_functions;

LIMITATIONS

mod_perl2 support is considered experimental and may contain bugs.
