'|' . $lab->{label}; next LOOP; } # or fit into empty space on existing line my $len = length($lab->{label}) + 1; if (substr($line, $lab->{start}, $len) eq ' ' x $len) { substr($line, $lab->{start}, $len,'|' . $lab->{label}); next LOOP; } } # or create a new line if needed push @lines, ' ' x $lab->{start} . '|' . $lab->{label}; } print "$_\n" for @lines;

UPDATE: added comments, added fitting new label into blank space, improved flow

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
