The ideal state is a graphic interface where the exercises are presented on the screen to reduce the friction. Gotta start somewhere.
I am not going to put my personal email here, and I don't see an option to send private messages on hn, although it's probably out there somewhere. Probably in the commits, lol. Worst case, feel free to open an issue on the trane repo.
As a first ask, what do you think of this: https://github.com/1Password/typeshare?
I figured writing the UI in rust is probably not a good idea. The ecosystem for UI is very immature and the language itself is probably overkill. But doing it in typescript/html/css requires you to understand the internal data structures (all the JSON files you see in the courses are just serialized rust objects).
I found that repo and it seems like a promising approach to autogenerate the types and make the interaction easier.
