Hi Brad,
I'm not sure I understand your problem entirely. Here is some rough code that
you may be able to get to do what you want, though. Basically it relies on
having the $tt object available to your routine and passing the vfield routine
in the process vars.
my $tt;
sub vfield {
my $name = shift;
my $context = $tt->context();
my $stash = $context->stash();
my $fq_vfield = $stash->get($name);
my $line = $stash->get('line');
# ... do stuff
return "$fq_vfield @ $line";
}
$tt = Template->new();
$tt->process(\'[% vfield("test") %]', { line => 123,
test => 5
vfield => \&vfield } );
# grabs whatever is in the variable named "test". So output will be:
5 @ 123
