In addition to other changes, you may want to write trim like this:

sub trim { 
    my @out = wantarray ? @_ : shift;

    return "" unless @out;
    for (@out) {
        $_ = "" => next unless defined;
        tr/|\n\r//d;
        s/^\s+|\s+$//g;
    } 
    return @out; 
}

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
