[Catalyst] Need example of Catalyst with Mason View

[August R. Wohlt]

Hiya Justin et al,

I used to use TT2 about 5 years ago, but switched to mason about 3 years
ago. One of the better choices I've made IMHO. For catalyst, its setup is
straightforward:

create lib/MyApp/View/Mason.pm and within it, put one line to define the
temporary directory where apache will put its object files. I use an
application-specific directory since I have a number of different catalyst
apps and the mason defaults will clobber each other otherwise:

  package MyApp::View::Mason;

  use strict;
  use base 'Catalyst::View::Mason';

  __PACKAGE__->config->{data_dir} 
  1;

And then in lib/MyApp/Controller/Root.pm, I put a default subby like the
following which will serve any page out of the root/ directory as a mason
component. That way I don't have to keep defining controllers for everything
when I want to put most of my development application logic in mason
components anyway (that way I don't have to keep reloading apache on HUGE
applications that catalyst takes forever to load as a cgi):

  sub default : Private {
     my ( $self, $c ) 
     # what directory our default mason components are in:
     my $f 
     if ( -f $f ) {
         $c->stash->{template}          $c->forward("MyApp::View::Mason");
     }
  }

I have an override in apache for root/static for all those unprotected
things I don't want catalyst to touch, like dojo, yui, images, css, etc.

The use of lib/MyApp/Controller/Root.pm suggests a more recent version of
Catalyst. If you dont have a root controller, it's time to upgrade.

$c is available in every mason component, and so is $m like normal. Hope
that helps. Glad to see not everyone is drinking the TT2 kool-aid :-)
