sub trim_length { my($string, $desired_length) = @_; # edit: swiped idea from Tachyon if((length($string)) < $desired_length) { return $string; } my @words = split(" ", $string); my $clipped = ""; foreach(@words) { my $temp = $clipped; $clipped .= $_; if((length($clipped)) > $desired_length) { $clipped = $temp; last +; } } if((length($clipped)) == 0) { $clipped = substr($string, 0, $desired_length); } $clipped .= "..."; return $clipped }

Does the same as your code but with a little less effort. Breaks the string down into words, keeps adding words until it passes your minimum marker, then keeps the previous version. If the first word puts it over the minimum marker, then it goes back to the original $string and clips that.

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.
