This is definitely mostly about Igniter, incidentally about Nerves and Phoenix.

Both of those projects have generators that create a mix project. The convention in Nerves is a “poncho” project, that is, not quite an umbrella. You put Phoenix as thing_ui and Nerves as thing_firmware.

The firmware project puts the UI project as a path dependency. You copy and modify a ton of Phoenix config over the the firmware project. Then you run locally or compile firmware for your device from the firmware project.

I want to make a generator that does this all for you. It seems like igniter would be very helpful for patching config and such. But I’m uncertain if the --with approach works here for igniter.new and to what extent Igniter helps for this journey. I am fundamentally generating two separate mix projects and tying them together a bit.
