[ic] Trying to define a new filter

[Jonathan Clark]

[ic 4.6.4 / RH6.2]

Hi All,

I am trying to define a new filter in a GlobalSub in interchange.cfg.
As per the
I have:

GlobalSub <<EOR
sub new_filter {
        package Vend::Interpolate;
        $Filter{reverse} = sub { $val = shift; return scalar reverse
val  };
}
EOR

and, following a restart, on my page:

should be reversed:[filter reverse]jonathan[/filter]

but this produces:

should be reversed:jonathan


Looks like I'm not to be setting up the hash properly, I have tried to
follow the
docs(http://developer.akopia.com/cgi-bin/ic/docfly.html?mv_arg=ictags03%2e28
):

>You can define your own filters in a GlobalSub (or Sub or ActionMap):

Please can someone tell me what I am doing wrong. If you can give me a
complete example of setting up this filter from a GlobalSub and Sub I will
add an annotation to the docs.

Thanks,
