NAME

Maypole::Application - Universal Maypole Frontend

SYNOPSIS

     use Maypole::Application;
 
 

     use Maypole::Application qw(Config::YAML);
 
 

     use Maypole::Application qw(-Debug Config::YAML -Setup);
 
 

     use Maypole::Application qw(Config::YAML Loader -Setup -Debug);
 
 

     use Maypole::Application qw(-Debug2 MasonX AutoUntaint);
 
 

DESCRIPTION

This is a universal frontend for mod_perl1, mod_perl2, HTML::Mason and CGI.

Automatically determines the appropriate frontend for your environment (unless you want to use MasonX::Maypole, in which case include "MasonX" in the arguments).

Loads plugins supplied in the "use" statement.

Responds to flags supplied in the "use" statement.

Initializes the application's configuration object.

You can omit the Maypole::Plugin:: prefix from plugins. So Maypole::Plugin::Config::YAML becomes Config::YAML.

     use Maypole::Application qw(Config::YAML);
 
 

You can also set special flags like -Setup, -Debug and -Init.

     use Maypole::Application qw(-Debug Config::YAML -Setup);
 
 

The position of plugins in the chain is important, because they are loaded/executed in the same order they appear.

FRONTEND

Under mod_perl (1 or 2), selects Apache::MVC.

Otherwise, selects CGI::Maypole.

If "MasonX" is specified, sets MasonX::Maypole as the frontend. This currently also requires a mod_perl environment.

FLAGS

-Setup

     use Maypole::Application qw(-Setup);
 
 

is equivalent to

     use Maypole::Application;
     MyApp->setup;
 
 

Note that no options are passed to "setup()". You must ensure that the required model config parameters are set in "MyApp->config". See Maypole::Config for more information.

-Init

     use Maypole::Application qw(-Setup -Init);
 
 

is equivalent to

     use Maypole::Application;
     MyApp->setup;
     MyApp->init;
 
 

Note that the "-Setup" flag is required for the "-Init" flag to work.

In persistent environments (e.g. "mod_perl"), it is useful to call "init" once in the parent server, rather than at the beginning of the first request to each child server, in order to share the view code loaded during "init". Note that you must supply all the config data to your app before calling "setup" and "init", probably by using one of the "Maypole::Plugin::Config::*" plugins.

-Debug

     use Maypole::Application qw(-Debug);
 
 

is equivalent to

     use Maypole::Application;
     sub debug { 1 }
 
 

You can specify a higher debug level by saying "-Debug2" etc.
