Something else must be going on -- are you sure that package 'Foo' is included and 'compute()' is getting called? Are you sure that 'process()' is working properly (check return value). Here's an example that works for me, just copy them both into the same directory and run the first one:
#!/usr/bin/perl
use strict;
use Foo;
use Template;
my $template = Template->new();
my @data = ( 1, 2, 3 );
$template->process( \*DATA, { object => Foo->new,
data => \@data })
|| die "Cannot process: ", $template->error();
__DATA__
[% FOREACH d = data %]
The datum is [% d %] and the computed
result is '[% object.compute( d ) %]'
[% END %]
And the Foo object:
package Foo;
# save as Foo.pm
sub new {
my ( $class, %params ) = @_;
return bless( \%params, $class );
}
sub compute {
my ( $self, $data ) = @_;
return "compute() called with: $data";
}
1;
Running this I get the expected:
$ perl test_tt_method.pl
The datum is 1 and the computed
result is 'compute() called with: 1'
The datum is 2 and the computed
result is 'compute() called with: 2'
The datum is 3 and the computed
result is 'compute() called with: 3'
Good luck!
