Word wrap in Ruby

word-wrap

# we can change the <wbr> and <br> as per our requirement.
  def wrap_long_string(text, max_width = 20)
    if text.blank?
      return text
    end
    
    sp = text.split(/\n/)
    sp.collect!{|s|
      s = (s.length < max_width) ? s : s.scan(/.{1,#{max_width}}/).join("<wbr>") 
    }
    return sp.join('<br/>')
  end

Change /.{1,#{max_width}}/ to /.{1,#{max_width}}\s/
