Format output to 40 characters long per line

Question

I\'m fairly new to Ruby and I\'ve been searching Google for a few hours now. Does anyone know how to format the output of a print to be no more than 40 characters long?

Answer 1

Ruby 1.9 (and not overly efficient):

>> x.join(" ").each_char.each_slice(40).to_a.map(&:join)
=> ["This is a simple sentence. This simple s", "entence appears on three lines."]

The reason your solution doesn't work is that all the individual strings are shorter than 40 characters, so n[0..40] always is the entire string.
