- The list operator promotes scalars to lists (it's a no-op for lists),
so you can reliably write:
[% cgi.checkbox_group('list', fooey).list.join("\n") %]
Although checkbox_group is still called in array context,
the list operator saves you in the case where checkbox_group
returns a single-element list, which TT demotes to a scalar.
- Use the experimental stash Template::Stash::Context, which allows
you to call plugin functions in scalar context using the new
virtual "scalar" operator. Here's a complete example:
use Template;
use Template::Stash::Context;
use CGI;
my $args = {
cgi => CGI->new,
fooey => [qw/foo bar baz/],
};
my $stash = Template::Stash::Context->new($args);
my $tt = Template->new({ STASH => $stash });
$tt->process(\*DATA, $args) or die $tt->error();
__END__
[% cgi.h1("Test") %]
[% cgi.checkbox_group('list', fooey).scalar %]
[% cgi.checkbox_group('list', ["abc"]).scalar %]
