I have a script which parses /etc/log/maillog and builds a hash of bounced email addresses, doing a few database interactions to identify the names and phone numbers of the recipients going without their email.

Today I'm adding Template::Latex to the mix to generate a report which might be useful for tracking down corrections to the bouncing email. But for some reason my variable substitutions are not happening.

My template includes the following:

[% FOREACH recipient IN call_list %]
    \textbf{recipient.email} & box & recipient.uid: recipient.name & r
+ecipient.fname recipient.lname & recipient.phones \\
    \hline
    [% FOREACH sponsor IN call_list.recipient.upstream %]
        \multicolumn{2}{||r|}{sponsor.email} & sponsor.uid: sponsor.na
+me & sponsor.fname sponsor.lname & sponsor.phones \\
    [% END %]
    \hline
[% END %]
[download]

The script itself includes:

sub produce_report {
  my $call_list = shift;
  my $vars = { 'call_list' => $call_list };
  print Dumper($vars);
  $tt->process('nightly_bounced_emails_report.tex.tt2',
                $vars,
                'bounced_email_report.pdf',
                binmode => 1) || die $tt->error();

  return;
}

$call_list arrives as a hashref, with the bouncing email addresses used as keys, each containing a data structure for the bounced recipient, plus a key called 'upstream', which includes an arrayref of anonymous hashes for the folks who brought the bounced recipient into the mix.

When the template is processed, it is producing a .tex file including:

    \textbf{recipient.email} & box & recipient.uid: recipient.name & r
+ecipient.fname recipient.lname & recipient.phones \\
    \hline

    \hline

    \textbf{recipient.email} & box & recipient.uid: recipient.name & r
+ecipient.fname recipient.lname & recipient.phones \\
    \hline

    \hline

And it never descends into the data structure to process the internal loop.

Can anyone please advise how I can get my template variables interpolated instead, please?

Any clues appreciated.
