Catalyst::View::Component::SubInclude::Visit - visit() plugin for C::V::Component::SubInclude

=head1 VERSION

Version 0.07_03

=cut

our $VERSION = '0.07_03';
$VERSION = eval $VERSION;

=head1 SYNOPSIS

In your view class:

  package MyApp::View::TT;
  use Moose;

  extends 'Catalyst::View::TT';
  with 'Catalyst::View::Component::SubInclude';

  __PACKAGE__->config( subinclude_plugin => 'Visit' );

Then, somewhere in your templates:

  [% subinclude('/my/widget') %]

=head1 DESCRIPTION

C<Catalyst::View::Component::SubInclude::Visit> uses C<< $c->visit() >> to 
render subinclude contents.

This method is only supported when using L<Catalyst> version 5.71000 or newer.

B<WARNING: As of Catalyst version 5.71000, this plugin doesn't work for chained 
actions with captured arguments>. Apparently, C<visit> doesn't handle this type 
of actions yet.

=head1 CLASS METHODS

=head2 C<generate_subinclude( $c, $path, @args )>

This is (roughly) equivalent to the following call:

  $c->visit( $path, @args );

But it will handle all the nasty details such as localizing the stash, 
parameters and response body. This is necessary to keep behavior consistent 
with the other plugins.

has keep_stash => (
    isa => Bool,
    is => 'ro',
    default => 0,
);

sub generate_subinclude {
    my ($self, $c, $path, @params) = @_;

    croak "subincludes through visit() require Catalyst version 5.71000 or newer"
        unless $c->can('visit');

    {
        local $c->{stash} = $self->keep_stash ? $c->{stash} : {};
        
        local $c->request->{parameters} = 
            ref $params[-1] eq 'HASH' ? pop @params : {};

        local $c->response->{body};

        my $captures = ref $params[0] eq 'ARRAY' ? shift @params : [];
        $c->visit( $path, $captures, \@params );

        return $c->response->{body};
    }

}
