Word Wrapping

Hi all,
        Is there any gem or plugin for "word wrapping".

The reason is I'm trying to generate a pdf from my application. There
are issues when I am trying to display long strings with no spaces. A
word wrapper should solve the issue I guess.

Any help would be appreciated.

Thanks

Why don't you write your own routine to wrap text? Here is a simple
one.

def wrap_text(txt, col = 80)
  txt.gsub(/(.{1,#{col}})( +|$\n?)|(.{1,#{col}})/,
    "\\1\\3\n")
end

Have a look at http://blog.macromates.com/2006/wrapping-text-with-regular-expressions/
for explanation.
