Well no. It can get pretty messy. But it's messy in a structured way I guess.
I think this is easier to touch by a newcomer than the current quote and syn backend.

Alright, rewriting the device-driver backend with askama. I've set it up so the old backend is still leading but the new one is run in parallel. Then it prints a diff between the two so I can see if I've got all of the details right.

Pretty chill workflow for converting :D

Askama let's go!

Maybe my gripe is not having a template engine. All the popular ones in Rust have examples with html templates and say they're inspired by jinja. (I don't know jinja)

Maybe I should look into Askama. It looks nice...?

If you do codegen, what's the best way to generate the final text output?

Right now I'm using quote, syn and proc_macro2, but I want to leave the TCU and maybe generate C code in the future too.

So I've been replacing quote with format! and tokenstream with String. But that feels wrong...

Is there a better way to structure this?

Literally the worst crate ever? 1 star

Ok! KDL is pretty nice! Little test of how device-driver in KDL could look like. Almost as nice to write as the existing DSL, but it's still a real document format.

Maybe maybe this is nice enough to get rid of the DLS and yaml/json. (Though I'd have to provide a good upgrade path)

Simulation results of how much a home battery could've saved me last year (with 2027 prices). No trading, just a simple charge when exporting and discharge when importing.

These results are... disappointing. A 10 kWh battery saves €190, but costs ~€4000. So it'd take 21 years to recoup.

The answer is about 15 seconds (when file is already loaded into RAM).Not good, but not too bad I guess

Maybe silly idea?

What if device-driver could also generate C headers? Maybe 'normal' embedded people would use it and publish it. Then we (the crab people) would get low level drivers for (almost) free!
