That's because Darren misread your request. What he thought you'd written
is this:
# pass everything in under the SUI key
my $tt = Template->new();
$tt->process("foo.tt2", { SUI => \%SUI })
or die $tt->error;
Not
# pass everything in as a top level
my $tt = Template->new();
$tt->process("foo.tt2", \%SUI )
or die $tt->error;
What you really want to know in TT is a way of seeing every variable that
is defined in the stash at all. I can't think of an easy way to do this
within TT. You're not the first person to ask for this either (Tom Insam
asked about this a few months back iirc.)
>From Perl space, this is fairly simply of course:
# dump out what we've about to pass in
use Data::Dumper;
print STDERR Dumper(\%SUI); # print to the apache log everything
# pass everything in as a top level
my $tt = Template->new();
$tt->process("foo.tt2", \%SUI )
or die $tt->error;
I hope that helps.
Mark.
