CGI::Application is a framework for building reusable web-applications.

SYNOPSIS

# In "WebApp.pm"...
package WebApp;
use base CGI::Application;

# ( setup() can even be skipped for common cases. See docs below. )
sub setup {
my $self = shift;
$self->start_mode(mode1);
$self->mode_param(rm);
$self->run_modes(
mode1 => do_stuff,
mode2 => do_more_stuff,
mode3 => do_something_else
);
}
sub do_stuff { ... }
sub do_more_stuff { ... }
sub do_something_else { ... }
1;


### In "webapp.cgi"...

CGI::Application is intended to make it easier to create sophisticated, high-performance, reusable web-based applications. This module implements a methodology which, if followed, will make your web software easier to design, easier to document, easier to write, and easier to evolve.

CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system or web server.

Rainlendar project is a customizable desktop calendar.
Rainlendar is a feature rich calendar application that is easy to use and doesnt take much space on your desktop. The application is platform independent so you can run it both on Windows and on Linux. The appearance can be customized with skins and you can even mix different skins together.
It is possible to use Rainlendar with other calendar applications too. Rainlendar uses the standard iCalendar format to store its events and tasks so you can easily transfer them between applications. You can also subscribe to online calendars and see your Outlook appointments directly in Rainlendar*.
Rainlendar is an unicode application and support localization so you can use it on your own language.
All the coming events are shown in a separate list where you can see the weeks events at one glance. You can decide how many days in advance you want to see in the list. Different events can have a different appearance in the list so you can easily spot the important events from the others. The icons in the calendar are also available in the event list and other windows to make it easier to separate the events.
You can also have a separate list for your long term tasks. The task list can be arranged several ways so that you can keep it better organized. You can also set a due date for the tasks to make sure youll remember to do them on time.
Youll also get an alarm when an event or task is due so that you dont miss it. The alarm can be defined to be set off any duration before the actual event so you have time to prepare for it.
And thats not all. Check the list of features for better overview of all the things Rainlendar can do. If you find it useful go to the download page and get yourself a copy.

OpenPlugin::Application is a subclass of CGI::Application, meant to help you create reusable web applications.

SYNOPSIS

# Example from OpenThoughts Demo.pm

package Demo;
use base "OpenPlugin::Application";
sub setup {
my $self = shift;
$self->run_modes(
mode1 => init_demo,
mode2 => get_os_list,
mode3 => get_os_info,
);
$self->start_mode( mode1 );
$self->mode_param(run_mode);
}
sub init_demo { ... }
sub get_os_list { ... }
sub get_os_info { ... }
1;

# Example from OpenThoughts demo.pl

#!/usr/bin/perl -wT
use strict;
my $r = shift;
my $demo = Demo->new( PARAMS => {
config => { src => "/path/to/OpenPlugin.conf" },
request => { apache => $r },
});

$demo->run();

OpenPlugin::Application is built on Jesse Erlbaums popular CGI::Application module. OpenPlugin::Application is simply a subclass of CGI::Application. Jesse says the following about CGI::Application:

"CGI::Application is intended to make it easier to create sophisticated, reusable web-based applications. This module implements a methodology which, if followed, will make your web software easier to design, easier to document, easier to write, and easier to evolve."

How does it do this? Jesse goes on to say:

"The guiding philosophy behind CGI::Application is that a web-based application can be organized into a specific set of "Run-Modes." Each Run-Mode is roughly analogous to a single screen (a form, some output, etc.). All the Run-Modes are managed by a single "Application Module" which is a Perl module. In your web servers document space there is an "Instance Script" which is called by the web server"

The biggest difference between CGI::Application and OpenPlugin::Application is that query object they both use; one is designed to use CGI.pm, the other OpenPlugin. Generally speaking, everything in the still applies. Any differences will be noted in this document.
It is not necessary to use OpenPlugin::Application in order to build web applications using OpenPlugin. This plugin is meant to be for your convenience -- to help you structure your web applications in a manner which makes sense, and is reusable.
