[Dancer-users] idiom for programming the Perl OO way with Dancer

3 Aug 2010

      The following would hopefully be a welcome change from my usual "I
can't deploy" emails ;-).

I am looking for the right idiom(s) for programming correctly with
Dancer. Right now, my dance.pm looks a mess

    package dance;
    use Dancer ':syntax';

    # bunch of modules #####################
    use Tie::File;
    use Tie::File::AsHash;
    use URI::Escape;

    use lib '/Users/punkish/Library/Perl';
    use Markdown 'markdown';

    my $markdown_opts = {url_prefix => '/', url_pattern => '-'};
    # end bunch of modules #################

    our $VERSION = '0.1';

    get '/*?' => sub {
        my ($p) = splat;
        my $page_name = $p ? $p : config->{default_page};

        if ( $page_name =~ /slideshow/ ) {
            template 'album.tt', {..};
        }
        elsif ($page_name =~ /maps/ {
            template 'map.tt', {..};
        }
        elsif ($page_name =~ /something_else/ {
            template 'something_else.tt', {..};
        }
        else {
            template 'default.tt', {..};
        }
    };

    sub slideshow {
        ..
    }

    sub maps {
        ..
    }

    sub something_else {
        ..
    }

The above is just the beginning. All those subs and methods not only
make for a very long dance.pm, they also clash syntactically with
Dancer's magic "get '/' => sub {}" idiom.

Now, in the world of CGI::Application, I would actually sub-class
CGI::Application, add my custom methods and junk to it, and then
sub-class that custom instance into my application instance which
would then be clean. Yes, I know, I am sweeping the crap under the
carpet, but at least the carpet it clean.

Is there something like that I can do with Dancer? Can I create a
sub-class of Dancer, add my custom stuff to it, and then create
application instances with it and program with it the Perl OO way?

Has someone written a tute on that? :-)
