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)

Here’s one way to do it:

string.gsub(/(.{75,}?\S*)\s+/, “\1\n”)

It meets the criteria of “around every 80ish character”… :slight_smile:

gsub(/(.{1,#{width}})(\s+|\Z)/, “\1\n”)

I know you have been served well but I would like to take advantage to
point to a RubyQuiz as there are surprisingly often
answers to Ruby programming questions. Yours was handled here
http://rubyquiz.com/quiz113.html

BTW James, will the Quiz page remain available after your retierement?

Cheers
