# => Once upon a time, in a kingdom called Far Far Away, a king fell ill, and finding\na successor to the throne turned out to be more trouble than anyone could have\nimagined...

word_wrap('Once upon a time', line_width: 8)
# => Once\nupon a\ntime

word_wrap('Once upon a time', line_width: 1)
# => Once\nupon\na\ntime

You can also specify a custom +break_sequence+ ("\n" by default)

word_wrap('Once upon a time', line_width: 1, break_sequence: "\r\n")
# => Once\r\nupon\r\na\r\ntime
