You could divide in two functions, or just merge them, returning a
boolean when the output_rule is empty, and returning a string otherwise.

I agree with you, It is rather ugly. As someone that didn't come from
a CS background, I remember finding the regex syntax very daunting
to say the least at first sight. In fact, I didn't get it at first.

That being said, though, the flip side is that those rather ugly codes
are pretty handy tools to have at hand from time to time.
