You can return immediately if the string is less than or equal to the desired length. Then it depends on what you want to do to make it pretty. I have a couple of routines like this:

sub shorten_string { my ( $string, $length ) = @_; $length ||= 64; $length = 10 if $length < 10; return $string unless length($string) > $length; my $chunk = int($length/2)-3; return substr($string,0,$chunk+1) . ' ... ' . substr($string,-$chunk +); } sub shorten_url { my ( $url, $length ) = @_; $length ||= 64; return $url unless $url and length($url) > $length; ( $url ) = split /\?/, $url; return $url if length($url) < $length or $url =~ m!\w+://[^/]+/?$!; $url =~ s!(\w+://[^/]+)!!; my $domain = $1 ? "$1/ ... " : '... '; $length -= length $domain; return $domain if $length < 1; my @bits = split '/', $url; my @keepers = $url =~ m!/$! ? ('') : (); my $tail = 1; while ( my $bit = pop @bits ) { next unless $bit; $length -= (length($bit) + 1); unshift @keepers, $bit if $tail or $length > 0; $tail = 0; last if $length < 1; } return @keepers ? ( "$domain/".join'/',@keepers ) : $domain; }

  • 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.
