The article quotes a code sample from FitNesse – the author has apparently maintained that codebase since then. You can check out the code for the current version at https://github.com/unclebob/fitnesse, or browse the code in a Monaco editor using https://github1s.com/unclebob/fitnesse/blob/HEAD/src/. (I have no idea if that code is “well-regarded”, but as you wrote, you can read it for yourself.)
