I have a string = "this is text that    I   want to 9 9.90  89 9 ii8 u"

using str = string.gsub(/(?!\d)\b\s\b(?!\d)/,'-')

i get "this-is-text-that    I   want-to 9 9.90  89 9-ii8-u"
                                                    ^   ^

there problem is that I do not want the "-" to show up if the last char is a digit or the first chat is a digit.  Got real close, but I think I need lookbehind which is not supported in ruby?
