Tom Thank you so much for the offer!
My code is here: https://github.com/BrianAtDocumentedDesigns/RenumKicadPCB It needs to be seriously reworked in order to incorporate into Kicad because of the way it works. I read in the project sch, pcb, and netlist files. I scan the PCB file and create a list of components. Then I do a "rules based" sort of the components, create a was/is list, and essentially do a "search and replace" on the .sch, .pcb, and netlist files. This involves recursing through the root schematic, which is a little tricky. This means the code is highly dependent on the file formats and does not update times stamps, etc.. Nevertheless, the utility has been downloaded a fair number of times. I no of no non-Kicad related issues. I apologize if the code is not up to professional standards but I try. I believe it would be very easy to adopt the code to fit into Kicad entirely. Instead of parsing the PCB and sch file formats I could use the built-in Kicad structures, and instead of doing a text search and replace I'd update the structures as is done in Annotate or Edit inside Kicad. So I'd have to go from c to c++ coding but also tie directly into eeSchema and PCBNew and using the objects and functions. Since much of what my utility does is already inside Kicad its just a question of figuring out where the existing functions and structures are and using those (of course, since I am used to c, and not c++, my terminology is all wrong but I am sure you understand what I mean). My initial thoughts were to modify PCBNewto write a was/is file then modify eeSchema to use that was/is file to re-annotate the schematic. That could, of course result in file coherence issues. The Kweilin approach would greatly simplify this since I would not have to add a new file formation and require the user to run a command in PCBNew then run another tool in eeSchema. On reflection, it did occur to me that a similar approach might allow forward/backward annotation (i.e. a change to the schematic reference designation being immediately reflected in the PCB and vice versa) but that is another thing to think about. I am having trouble finding KiwayMailln source but I'll figure that out. How I am going to do this is, of course, evolving. In the past I discovered you really don't understand a problem the first time you solve it. Since this will be my second go around, I'll probably do it better but I'll only understand the approach after I have studied the PCBNew and eeSchema source. Based on my analysis of eeSchema, despite my limited grasp of c++, I can see that updating the schematics annotation is quite straightforward from inside eeSchema - its basically the annotate function except, instead of generating a new annotation I incorporate the was/is information. I have to study PCBnew to figure out how to extract the component information and relay that to eeSchema (presumably by KiwailMailln). The sorting, etc., is already written in my utility, so I'd just have to rewrite that in c++ as necessary. If you give me a day or so I'll be delighted to send you example of my dialogs. They are very simple - quite similar to the annotation dialog in eeSchema.

How do I go about this? > Hi Brian, Others have already answered to your questions so here's my offer: I believe geographical annotation is a very useful feature so I can offer a bit of my help. Point me to: - the latest sources of your tool, - a sketch of the user interface (dialogs), can be a hand-made drawing - a brief description of how you want all this to work (in terms of user experience). Once I have this information, I'll try making a basic port of your code to Kicad codebase to the stage where you could take it over and contribute further features/fixes on your own.
