I have a series of text that contains mixed numbers (ie: a whole part and a fractional part). The problem is that the text is full of human-coded sloppiness: The whole part may or may not exist (ex: "10") The fractional part may or may not exist (ex: "1/3") The two parts may be separated by spaces and/or a hyphens (ex: "10 1/3", "10-1/...

Searching through here, I've found http://www.rubular.com/ which is useful, but not what I found originally. Today, I found a few testing tools through google, but most often they are slow, don't allow you to test as-you-type, or ...

I liked the...
