            qr|/([^/]+)/([^/]+)/?|                => { names =>
                                                         [qw(app rm)]
                                                     },
            qr|/([^/]+)/([^/]+)/page(\d+)\.html?| => { names =>
                                                         [qw(app rm page)]
                                                     },
        ],
    );

DESCRIPTION ^

CGI::Application::Dispatch uses its own syntax dispatch table. CGI::Application::Dispatch::Regexp allows one to use flexible and powerful Perl regular expressions to transform a path into argument list.

DISPATCH TABLE ^

The dispatch table should contain list of regular expressions with hashref of corresponding parameters. Hash element 'names' is a list of names of regular expression groups. The default table looks like this:

        table       => [
            qr|/([^/]+)/?|          => { names => ['app']      },
            qr|/([^/]+)/([^/]+)/?|  => { names => [qw(app rm)] },
        ],

Here's an example of defining a custom 'page' parameter:

        qr|/([^/]+)/([^/]+)/page(\d+)\.html/?| => {
            names => [qw(app rm page)],
        },
