Wish I could comment on the routing like others but the render is stuck at 96.2% for me. Nothing else on the page shows it on my phone so I assume that's the problem. (And of course nothing in the log of error tabs).

I think just looking at the first code example you can already see the problem. A lot of duplication and hand written or auto generated code. I thought the point was to define it in the code. Put an array of pin functions. For loop the footprint. That kinda thing. This looks like a mess to get started with and even worse is at higher point count parts it looks like it'll balloon in maintainability. Altium has very solid footprint generators with a nice menu. This looks like it's missing an overarching API for creating these long lists of parameters. Doesn't feel like the juice is worth the squeeze on this one. If it's a simple schematic, just do it by hand. If it's complicated, this feels harder to wrangle.

Another example of weird code is the previousLedName. Like like really that variable isn't used and the first term of the && should be that indeed check. But even more so, it should be an if statement not rely on remembering short circuiting (lazy evaluation) tricks. Because that's what you mean. You mean if it's not the first one, connect to the previous one. So, the code should say that. I find it hard to believe such a high level language would prevent it.

I think the pin label lists don't make sense. They're maps where the value is an array where the first element is the key? Why is this not just a list of pin numbers to names or a map of they're not contiguous whole numbers?

And then the icing on the cake: you still have to define where in XY everything is.

So really, in thinking about this, this looks more like a file format than a tool. And maybe that's fine. But I'll stick to the native formats of the tools.
