Re: Parse template into data structure

Without getting too complicated - here are the basics.

use Template;

{
    package MyStash;
    use base qw(Template::Stash);

    sub undefined {
        my $self = shift;
        my @ident = shift;

        print "(".join("|",@ident).")\n";

        if (@ident > 1) {
            return '';
        } elsif ($ident[0] eq 'adjective') {
            return 'red';
        } elsif ($ident[0] eq 'noun') {
            return 'fox';
        } elsif ($ident[0] eq 'verb') {
            return 'jumped';
        } else {
            return '';
        }
    }
}

my $stash  = MyStash->new;
my $string = "The [% adjective %] [% noun %] [% verb %] over the river
+.\n";
Template->new(STASH => $stash)->process(\$string);

And if you'd rather use CGI::Ex::Template (which is Template::Toolkit compatible template wise) you could use the following code (I'd use CGI::Ex::Template personally - but that might be because I'm intimately familiar with it :)). `use CGI::Ex::Template; my $cet = CGI::Ex::Template->new( UNDEFINED_GET => sub { my $self = shift; my $ident = shift; print "(".join("\|",@$ident).")\n"; if (@$ident > 2) { return ''; } elsif ($ident->[0] eq 'adjective') { return 'red'; } elsif ($ident->[0] eq 'noun') { return 'fox'; } elsif ($ident->[0] eq 'verb') { return 'jumped'; } else { return ''; } }, ); my $string = "The [% adjective %] [% noun %] [% verb %] over the river +.\n"; $cet->process(\$string);` [download] my @a=qw(random brilliant braindead); print $a[rand(@a)];	[reply] [d/l]

UNDEFINED_GET in this package appears to be able to do what I had in mind. I will have to take some time to play with it a bit. Thank you.	[reply]
