For reference, Rails has word_wrap: http://apidock.com/rails/ActionView/Helpers/TextHelper/word_wrap word_wrap(text, options = {}) public Wraps the text into lines no longer than line_width width. This method breaks on the first whitespace character that does not exceed line_width (which is 80 by default). word_wrap('Once upon a time') # => Once upon a time word_wrap('Once upon a time, in a kingdom called Far Far Away, a king fell ill, and finding a successor to the throne turned out to be more trouble than anyone could have imagined...') # => 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 -- Martin Vidner, YaST Team http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu
