[discussion] make position of pin numbers within connectors consistent?

Currently, pin numbers appear on the left or the right of the connector's pin table depending on which side the wires come out.

This was implemented since the very first draft of WireViz and has remained unchanged. As more and more fields can/will be defined on a pin level (pin labels, color, notes, shorts/bridges, ...), it can cause confusion.
And when daisy-chaining connectors horizontally, duplicating the pin number on both edges can look silly, especially if no other pin attributes are defined.

Should pin numbers always appear on the left, to keep the order of the columns consistent across all connectors?
Personally, I am leaning more and more in favor of this solution.

I use these wireviz drawings to document cabling and to assist technicians with construction cables. Our techs like the pin numbers next to the wires, as that's the information they use most when making the cable. Many times, they don't care about or refer to the signal name. I'd prefer to move the signal names into the rightmost column after the shorts, so that it's a mirror image of the left connector.

Some thought that I have been considering to post as a feature request recently: Currently, pin activation takes effect on both sides of the connector, causing the entire pin list to be shown on whichever side there is any connection. Should it also be possible to show individual pin listings on the left and right side of connectors? Or would it just overcomplicate things?

That was the thinking behind the initial behavior :)

I wrote #404 (comment) under the assumption that hide_disconnected_pins is active. IMO this should treat both sides independently to produce a more compact output. Any opinions on this?

First, I would not talk about left and right but rather see it like an onion, with a core, outside, and inside (currently empty) layers. Currently, the outside layer is always th Nr. and then the core goes lable and jumpers

Second, I think that this outside and inside layers are mirrored if wiers are connected to both sides of the connector.

It would be reasonable to put the lable into the first inside layer.

It would also be good if it would be selectable if these layers are always left, right, both sides or auto(similar to current).

It would also be reasonable if it would be possible to select if the lable is part of the core or layer.

I think that things like the jumpers should remain in the core.

• When hiding disconnected pins, it makes sense to hide the whole row because no information about those pins are needed.
• Pins that are connected at one side and disconnected at the other side in the diagram, are indeed connected in real life, and all information about them are needed. Do you want to replace the pin name at the disconnected side with an empty cell? That will not be more compact. I don't really see the benefit. Please elaborate.
