instance method
word_wrap
Ruby on Rails 3.0.20
Since v2.2.3Signature
word_wrap(text, *args)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).
Examples
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\n a successor to the throne turned out to be more trouble than anyone could have\n imagined... word_wrap('Once upon a time', :line_width => 8) # => Once upon\na time word_wrap('Once upon a time', :line_width => 1) # => Once\nupon\na\ntime
You can still use word_wrap with the old API that accepts the line_width as its optional second parameter:
word_wrap('Once upon a time', 8) # => Once upon\na time
