This should probably be asked on the CGI::Application mailing list, but I'll
answer it anyway.
The load_tmpl function in CGI::Application is really just a helper function, and
doesn't need to be used in order to use HTML::Template. Just create the
template object yourself in your run modes.
my $template = HTML::Template::Expr->new(...);
If you really want to use the load_tmpl function in your code, then override it
with your own version.
sub load_tmpl {
my $self = shift;
my ($tmpl_file, @extra_params) = @_;
# add tmpl_path to path array of one is set, otherwise add a path arg
if (my $tmpl_path = $self->tmpl_path) {
my $found = 0;
for( my $x = 0; $x < @extra_params; $x += 2 ) {
if ($extra_params[$x] eq 'path' and
ref $extra_params[$x+1] and
ref $extra_params[$x+1] eq 'ARRAY') {
unshift @{$extra_params[$x+1]}, $tmpl_path;
$found = 1;
last;
}
}
push(@extra_params, path => [ $tmpl_path ]) unless $found;
}
require HTML::Template::Expr;
my $t = HTML::Template::Expr->new_file($tmpl_file, @extra_params);
return $t;
}
All I have done here is taken the exact load_tmpl function from
CGI::Application, and changed the HTML::Template calls to HTML::Template::Expr.
Put this in your superclass and all your template objects will be Expr objects.
You will have a performance hit on your templates that don't require H::T::E, so
I would recommend you use the first method. Or perhaps even better, create a
load_tmpl_expr function that uses HTML::Template::Expr and leave load_tmpl as
is. That would give you the option to choose the right one in your run mode.
That might not be a bad addition to the CGI::Application core...
