The following is an answer I got last year on the Catalyst mailing
list, it worked for me, but I haven't really done much more than play
with it.

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} = "/workplace/MyApp/data";
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 = $c->path_to('root', @{$c->req->args});
if ( -f $f ) {
$c->stash->{template} = $f->relative($c->path_to('root')) ."";
$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 :-)
