NAME
    Dancer::Plugin::Hosts - Config trigger for virtual sites

NOTES BEFORE
    After this module has been written i found other way to make virtual
    hosts without this module. Please to see "OTHER WAY" section below

SYNOPSIS
    This plugin doesn't have syntax commands. It has only configurable
    options in Dancer config file. It changes appdir & application settings
    by seeing in "Host:" HTTP header. For every site you can use different
    directories and application settings in one Dancer process (author
    tested from Starman + Dancer bundle). Also you can use your own signle
    'App' module for some sites. Additional you can set any your own
    settings as Dancer::setting command does.

        use Dancer;
        use Dancer::Plugin::Hosts;

        get '/' => sub {
            template 'foo';
        };

        dance;

CONFIGURATION
  Example
        plugins:
            Hosts:
                http://app1.foo.com:
                    alias: http://www.app1.foo.com
                    appdir: /foo-2/dir
                    application: My::App1

                http://app1.foo2.com:
                    alias: http://www.app1.foo2.com
                    appdir: /foo-2/dir
                    public: /where/public/dir

                    # 'confdir' will be as "$appdir" setting
                    # 'views' will be as "$appdir/veiws"
                    # 'public' will be as "/where/public/dir"

                    # Here we use same module of application as in previous example
                    application: My::App1

                http://app2.foo.com:
                    alias: http://www.app2.foo.com
                    appdir: /foo-3/dir

                    # Here no 'application'
                    # so will be used 'main' App of Dancer

                # Here site is located at 81th port
                http://app3.foo.com:81:
                    appdir: /foo-4/dir
                    application: My::App3

PLUGIN OPTIONS
  appdir
    *This option is required*. If you have only one "appdir" setting for
    directory settings of one host site then other directory settings will
    be set to following values (as Dancer does itself):

        confdir     -> appdir
        public      -> appdir/public
        views       -> appdir/views

  application
    *This option is optional*. If you will define it then the module after
    it will be loaded if need through Dancer::load_app command and all
    settings for this host will be set for this App settings. Otherwise
    application will be 'main' (Dancer no App default)

OTHER WAY
  Example without using this module
    Here the example: one module (App) for some sites.

    *Your lib/YourApp.pm should be as:*

        package YourApp;

        use strict;
        use warnings;

        use Dancer ':syntax';

        setting apphandler => 'PSGI';

        Dancer::App->set_running_app('YourApp');

        # This and other routes ...
        get '/' => sub {
            # Static and template files will be from different directories are
            # based by host http header
            template 'index';
        };

        1;

    *Your bin/app.psgi should be as:*

        #!/usr/bin/perl
        use strict;
        use warnings;

        use Dancer;

        # The next line can miss but need for quickly loading in L<Starman> server
        use YourApp;

        use Plack::Builder;

        # Please notice that here no need ports in url
        # So for http://app1.foo.com:3000/ will work
        # http://app1.foo.com/
        my $hosts = {
          'http://app1.foo.com/' => '/appdir/1',
          'http://app2.foo.com/' => '/appdir/2'
        };

        builder {
            my $last;
            foreach my $host (keys %$hosts) {
                $last = mount $host => sub {
                    my $env = shift;
                    local $ENV{DANCER_APPDIR} = $hosts->{$host};
                    load_app "YourApp";
                    Dancer::App->set_running_app('YourApp');
                    setting appdir => $hosts->{$host};
                    Dancer::Config->load;
                    my $request = Dancer::Request->new( env => $env );
                    Dancer->dance($request);
                };
             }
            $last;
        };
