Basically your generate subroutine would look like:
sub generate {
my $hashref = shift;
my $template = HTML::Template->new(filename => "$tmpldir/generic.tt"
+);
$template->param(map { defined $hashref->{$_} ? ($_ => $hashref->{$_
+}) : () }
keys %$hashref);
);
print $template->output;
}
This works because HTML::Template::param expects a list an even number of elements in length suitable for hash type operations, and map of course produces lists, so our expression there utilizes the ternary operator (?:) to test for defined values and outputs key/value pairs.
I am not really qualified to give advice about template design since I'm new to it myself. But just the fact you're using them I can comfortably say is a good sign :)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
