Here's something I'm using. It can probably be done much more easily,
but I'm to busy to make it elegant. You can see what it's doing. I have
a minimum length, and I break at word boundaries. There's a lot of
improvements that could be made. For example, it doesn't recognize
punctuation, but it should.
/** Shorten string to max length and replace last three chars with an
ellipsis */
def shorten(in: String, len: Int): String = {
if (in.length > (10 max len)) {
val words = in.substring(0,(7 max (len - 3))).split(" ").toList
if (words.length > 1)
words.dropRight(1).reduceLeft(_ + " " + _) + "..."
else if (words.head.length > (7 max len))
words.head.substring(0, (7 max len)) + "..."
else
words.head + "..."
}
else
in
}
