The following adds a method to the string class called wrap which wraps a
string at the specified width broken on a space but honouring line endings
class String
def wrap(width)
gsub(/(.{1,#{width}})(\s+|\Z)/, "\\1\n")
end
end
s = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Maecenas
cursus cursus enim. Ut sit amet metus at lacus consectetuer condimentum.
Suspendisse nulla arcu, varius eget, consequat id, sodales sit amet, turpis.
Etiam ornare felis id augue. Morbi eleifend sem nec odio. Aenean augue dui,
placerat et, porta tincidunt, accumsan vitae, tortor. Ut et nulla et diam
gravida eleifend. Nulla fermentum ligula nec tellus. Donec quis purus id
nisl blandit fermentum. Nunc commodo metus sit amet tortor. Nam lacus quam,
ultricies sit amet, fermentum at, dictum eget, metus."
puts s.wrap(80)
