A while back I asked some help to find an easy way to draw some component diagrams with TIkZ. The answer was awesome, but when adaption the solution to my case, I ended up copy-pasting the same code several times.
Here is a part of the code (without all the copy-pasted code).

The styles ueast, uwest, unorth, usouth defines the use port to draw on every side of the component they're attached. The styles peast, pwest, pnorth, psouth define the provide ports. And there are 4 variations of them.
The plain one that draw black circles / half-circles.
One that draw thick green circles / half circles.
One that draw triangles as ports (not cut in half and shapes rotated).
One that draw squares (not cut in half).
So it's 4 variations of 8 styles, which makes 32 very similar TIkZ styles.
Is there a way to write those styles more concisely? Possibily without using macros to generate the code. Ideally, it would rotate automagically the port.
I can include the missing code if needed.
