Brian here.

My utility is up on GitHub as a standalone app. I learned enough c++ and wxWidgets so porting it to Kicad should be useful.

I set porting it to Kicad itself to the side for a few months so I could catch up with life and since it is destined for V6 (IIRC) I have some time.  While there is a lot of code in Kicad and lots of moving parts I have a clear path to porting it over using Kiway, etc.. Essentially this means 

1) Replacing my homebrew parsing of PCB, Schematic, and netlist files to calls to internal Kicad functions/methods in the respective apps;
2) Once this is done I’ll use Kiway to communicate the changes between eeSchema and PCBNew.

As near as I can determine, everything I need to extract from the files is already in Kicad.

When I set things aside I was trying to figure out what I needed to do in order to add a toolbar call in Tools to access my code. Since there seems to be numerous files associated with such a change I found it rather daunting.

If anybody wants to help they are welcome to reach out to me directly. 

Brian

Subject: Re: [Kicad-developers] Back annotate references from PCB

I thought that was part of the connectivity stuff that Jon was working on (it certainly wasn't me, and I don't know if there is another Ian contributing code right now). I remember seeing some email threads on real-time updates to the information in Eeschema.

The wishlist item that Wayne mentioned is [1]. Brian filed that a while ago because he had created a tool to do the back annotation based on the geography of the board. I don't know where he is with porting it into the KiCad codebase right now, but you should definitely reach out to him and coordinate work so that you don't duplicate effort.

I dimly remember that there was some work (Ian did that IIRC) to make the
netlist the master document and attach the schematic and PCB information to
that, with a first patch to keep the netlist up-to-date continuously.

It would probably make sense to join that effort, because any other
solution would conflict heavily with that.
