[rt-users] Having stripmime put a clickable link

[Frank Thommen]

hi lorens,

i did the following:

i added a subroutine 'print_url_list' to 'support.pm' and called this routine 
at the end of 'print_transaction' in 'support.pm'.  it prints a list of all 
http-urls occurring in the transaction (not only stripmime links) as clickable 
urls at the end of each transaction.

the regexp used to detect http-urls is not very good :-}.  you'll sometimes 
have to correct the url in your browser, but that should not be a big problem 
and - at least for me - is better than nothing.

the rest of the transaction is printed as preformatted text (<PRE>), therefore 
you cannot have any clickable links in it.  for 'optical conformance' the url 
list is printed in teletype style (<TT>).

any feedbacks for enhancements are welcome.


#
# this is tne new subroutine
#
sub print_url_list {
    my ($value) = shift;

    $url_regexp = 'http://([\w-])+(\.\1)*(/?[^ ])*[^\.]';

    if ($value =~ /$url_regexp/) {
      print "<tt><b>URL-List for this Transaction:</b><p>\n";

      while ($value =~ /$url_regexp/g) {
        $url = $&;
        print "* <a href=\"$url\" target=\"_new\">$url</a><br>\n";
      }

      print "</tt>\n";
    }
}


#
# this is the modified print_transaction
#
sub print_transaction {

    ...codecodecode...

    print "<pre>";
    &print_html($body);
    print "</pre>";

    &print_url_list($body);  #add here print_url_list
}
