Since Dancer doesn't support the concept of creating a base class, and then inheriting from it, how do I apply same settings to any route in any package or sub-package?

Who told you you can use inheritance with Dancer packages? Dancer does nothing for you regarding inheritance, but that doesn't mean you can't do it yourself:

package FooApp::Base;

use strict; use warnings;

use Dancer ':syntax';

sub opts {    return { base => 42 }; }

get '/' => sub {    "base opts : ".to_yaml(opts()); };

1;

package FooApp::Forum;

use strict; use warnings; use Dancer ':syntax';

use FooApp::Base; use base 'FooApp::Base';

sub opts {    my $self = shift;    my $parent_opts = $self->SUPER::opts();    return {        %{ $parent_opts },        forum => 34,    }; }

get '/' => sub {    "forum opts : ".to_yaml(FooApp::Forum->opts()); };

Tested with Dancer 1.1901 here, working.

Hope that helps,

This is great news, as it will greatly simplify my application. However, it doesn't work for me (also on 1.1901). My app structure is app.pl lib/ app.pm app/ app1.pm in app1.pm, I have ---- package app::app1; use Dancer ':syntax'; use lib ('/Users/punkish/Sites/app/lib'); use app; # do I really need this and the line just above it? use base 'app'; sub opts { my $self = shift; my $opts = $self->SUPER::opts(); return { %{ $opts }, app1 specific opts } }; ---- and, I get the following runtime error Can't call method "SUPER::opts" on an undefined value at /Users/punkish/Sites/app/lib/app/app1.pm line 16. /Users/punkish/Sites/app/lib/app/app1.pm around line 16 13 14 sub opts { 15 my $self = shift; 16 my $opts = $self->SUPER::opts(); 17 18 return { 19 %{ $opts },
