  • use Mason's templating parts, not its web framework parts, like you would with Catalyst or Jifty. see the source of Catalyst::View::Mason, and the "using Mason in standalone scripts" part of HTML::Mason::Admin.
    • (I'll be damned if I can get the code to format within <code> tags, so this is all Code format.)

      I actually tried installing Jifty last night because I realized it might be more what I had in mind (continuations, Mason...), but I aborted the install after about a half hour of exciting CPAN action. (Maybe I should try Catalyst I guess, but it's never really felt right to me..)

      Then I ended up doing just what you mentioned, using Mason as a standalone script. It wasn't very elegant, though. Unfortunately I didn't bring my laptop today so I can't copy what I have, but from memory it was something like this (based on the example in Continuity):

      my $server = Continuity->new(port => 65432);
      $server->run;  # (or whatever it is)

      sub main {
          my $request = shift;

          my $outbuf = '';
          my $interp = HTML::Mason::Interp->new(
              comp_root => '...',
              data_root => '...',
              out_method => \$outbuf,   # something like that

          my $num1 = $request->param('num');

          $outbuf = '';
          my $num2 = $request->param('num');

          $outbuf = '';
          $interp->exec('/sum.html', num1 => $num1, num2 => $num2, sum => $num1 + $num2);

      And there the components 'comp/num1.html' etc. are like:

      Enter first number:
      <input type=text name=num><input type=submit>


      <h2>The sum of <% $num1 %> and <% $num2 %> is <% $sum %>!</h2>
      $num1 => 0
      $num2 => 0
      $sum  => 0

      and 'autohandler' is like:

      % $m->call_next();

      So I guess whatever I did would basically wrap around this tedious incantation:


      I guess it's not even a matter of subclassing a mapper/adapter of Continuity or whatever, just making an "exec + print" method on the application side.
      • Yeah. In larger apps I usually end up putting $request into an instance variable so that I don't have to pass it around all the time. You can do the same thing with your Mason interpreter, I imagine your main body might look like:

        sub main {
            my $request = shift;
            my $app = App->new(request => $request);

        # ...

        sub run {
            my $self = shift;
            my $num1 = $self->param('num
