Re: Re: Template Toolkit 2 and subroutines

There are all kinds of things you CAN do in TT, but that doesn't mean you should do them.

I'm quite well aware of that, but thanks for reminding anyway ;)

What I want to do is really simple output processing (like substituting   for spaces in menus). I think that's something I can safely do in a template -- if not, I'll be happy to hear why before I go too far in a wrong direction :)

I checked merlyn's examples. Here are the results:

Template:

--cut here--
[% MACRO tr_test BLOCK %]
   join ':', @_;
[% END %]

[% PERL %]
   $stash->set( 'tr_test_2', sub { join ':', @_ } );
[% END %]

1: [% tr_test( 'test', '1' ) %]
2: [% tr_test_2( 'test', '2' ) %]
--cut here--
[download]

And the result:

--cut here--
 
 
 
 
1:
   join ':', @_;
 
2: test:2
--cut here--
[download]

So the latter does exactly what I need. Thanks for both answers.

I think that's something I can safely do in a template -- if not, I'll be happy to hear why before I go too far in a wrong direction :) Oh, then be sure to read Template::Filters to see how to do that properly.

In addition to the use of filters, you can pass a reference to any sub in as part of the stash. I sometimes pass in a URI escape subroutine from Apache::Util and use it like this in a template: `[% uri(foo.bar) %]`	[reply] [d/l]
