There *is* a method in class String - kind of:

irb(main):009:0> w = ["a", "b" * 17, "c" * 20, "d" * 25]
=> ["a", "bbbbbbbbbbbbbbbbb", "cccccccccccccccccccc",
"ddddddddddddddddddddddddd"]
irb(main):010:0> x = w.map {|s| s.sub(%r{\A(.{17}).{4,}\z}, '\\1...')}
=> ["a", "bbbbbbbbbbbbbbbbb", "cccccccccccccccccccc", "ddddddddddddddddd..."]
irb(main):011:0> x.map {|s| s.length}
=> [1, 17, 20, 20]

;-)

Kind regards

robert
