Re: [Mason] Piped Content and Perl conditionals.

[John Williams]

No.  The <&| tag must gather up the content and pass it to the component.

It should be thought of as a sort of control block, like eval{}, so in
compiled form, it looks *vaguely* like this, which would break up
your if statements.

$m->comp_with_content( content => "
  <!-- other html goes here -->
");


Here are a couple alternatives:

 <&| ($thing eq 'somecondition' ? '/some/piped/component/' : 
'/some/passthru/component'), %args >
<!-- where the passthru just returns the content unchanged -->
 </&>

... or ...

 <&| '/some/piped/component/', %args, nevermind => ($thing ne 'somecondition') >
  yada yada yada
 </&>

where the piped component begins with:

$m->print( $m->content ) if $ARGS{nevermind};

... or even ...

% if ($thing eq 'somecondition') {
<&| '/some/piped/component/', %args >
<& stuff &>
</&>
%} else {
<& stuff &>
%}
<%def stuff>
<!-- other html goes here -->
</%def>
