Very much like the param version just posted here. Insert tags of the
form:
<tmpl_set name=x value=y>
with _no_ quoting around the x and y (this is a quick-and-dirty hack);
each one will provide a value for a top-level parameter. You can't do
anything about values within loops with this.
package HTML::Template::Set;
use HTML::Template;
use base qw(HTML::Template);
sub new {
my %set_params;
my $set_filter = sub {
my $text_ref=shift;
my $match='<(?:\!--\s*)?tmpl_set\s*name=(.*?)\s*value=(.*?)\s*(?:--)?>';
my @taglist=$$text_ref =~ m/$match/gi;
while (@taglist) {
my ($t,$v)=(shift @taglist,shift @taglist);
$set_params{$t}=$v;
}
$$text_ref =~ s/$match/<tmpl_if name=never><tmpl_var name=$1><\/tmpl_if>/gi;
};
my $proto = shift;
my $class = ref($proto) || $proto;
my $self=HTML::Template->new(filter => $set_filter,
@_);
bless ($self, $class);
$self->param(%set_params);
return $self;
}
1;
