Apr 7, 2018 at 22:48 comment added Neil @JonathanAllan That doesn't help for the 1xw and the hx1 rectangles, but I've found a solution anyway, only cost another 20 bytes...

Apr 7, 2018 at 20:47 comment added Jonathan Allan Can you not just output [0,0,0,0] when nothing matched?
Apr 7, 2018 at 20:44 comment added Neil @JonathanAllan Ugh, in that case, I think I'd better delete my answer, since the regex required to match degenerate rectangles is going to be fiendishly complex.
Apr 7, 2018 at 20:26 comment added Jonathan Allan (by "points" I meant a single element would now be a 1x1 rectangle)
Apr 7, 2018 at 20:25 comment added Jonathan Allan ...and now it's been relaxed to make the lex check unnecessary.
Apr 7, 2018 at 20:23 comment added Neil Fixing the lexicographical order cost 20 bytes :-( and I noticed that the area calculation changed, which cost another 2 bytes, but I don't know what @JonathanAllan means about points.

Apr 7, 2018 at 20:14 comment added Jonathan Allan ...this will now need to match lines and points.
Apr 7, 2018 at 20:12 comment added danihp I just relaxed some restrictions (lexicographical-min requirement ). I hope don't be a problem for you.
Apr 7, 2018 at 20:03 comment added Jonathan Allan (...yeah first two values in output are the wrong way around I think)
Apr 7, 2018 at 19:53 comment added Jonathan Allan Fails the lexicographical-min requirement (try the test case I added to the OP for example) (maybe also output can be in the wrong order??) TIO
