How can I override WRAPPER in a Template Toolkit template file?

Question

Is there a way to disabling a WRAPPER that was set in new(\%config), through either the template, or a temporary override with parse()? I want to have a single default WRAPPER (that I'll use for 99.9% of my templates), but exclude a few.

I'm doing this all through Catalyst::View::TT just like the example in the configuration synopsis, except I don't want the WRAPPER to apply to all of my templates.

Edit the wrapper, to include a conditional like:

[% IF no_wrapper OR template.no_wrapper %] [% content %] [% ELSE %]
  top;
    [% content %]
  bottom;
[% END %]

This allows me to disable the wrapper either (1) inside of template, or (2) from the stash.

1. [%- META no_wrapper = 1 -%]
2. $c->stash->{no_wrapper} = 1

META var ...; is a directive that makes var accessible through the template hash as template.var

Define exceptions in site/wrapper itself, and btw there are exceptions defined there already.

[% IF template.name.match('\.(css|js|txt)');
     debug("Passing page through as text: $template.name");
     content;
   ELSE;
     debug("Applying HTML page layout wrappers to $template.name\n");
     content WRAPPER site/html + site/layout;
   END;
-%]

I stumbled into the same problem, and created a more generalized solution that allows for dynamic switching of layouts, or to have no layout at all. See here:
