Need Help??

Alternative with regex:

sub trimTo {
  my ($line, $length) = @_;
  $line =~ s/^(.{0,$length}\s|.{$length}).*/$1.../;
  return $line;
}

I think has the same behaviour as the others. Not tested fully. Not that I think it's any faster than any substr method, but it's an alternative.

Maybe just add a line to return the string when its length is shorter than the desired length. Otherwise, with a string like "this is a very long sentence", you get "this is a very long ..." instead of "this is a very long sentence". Thanks and cheers :)	[reply]

Yes, sorry about that. I'm sure there's a one character change that makes the regex not match when it's shorter than $length, but a) I can't see it immediately, b) that's just stupid golfing.	[reply]
