You may be interested in TextHelper's truncate function:

  truncate("Once upon a time in a world far far away")
  # => Once upon a time in a world f...

  truncate("Once upon a time in a world far far away", :length => 14)
  # => Once upon a...

  truncate("And they found that many people were sleeping better.", :length => 25, "(clipped)")
  # => And they found that many (clipped)

  truncate("And they found that many people were sleeping better.", :omission => "... (continued)", :length => 15)
  # => And they found... (continued)

Answer 2

'Once upon a time in a world far far away'.truncate(27)
"Once upon a time in a wo..."

'Once upon a time in a world far far away'.truncate(27, separator: ' ')
"Once upon a time in a..."

'Once upon a time in a world far far away'.truncate(27, separator: /\s/)
"Once upon a time in a..."

'And they found that many people were sleeping better.'.truncate(25, omission: '... (continued)')
"And they f... (continued)"
