> That said I totally get that writing specs are hard, so not dissing the authors as such. Oh definitely. Yeah maybe I come off as anti-spec or something, but in this case I just think MP was really well thought out, and then Bormann hung a bunch of stuff on it that really wasn't, and I'm salty haha. > Anyway I've only looked at CBOR and MessagePack when I dabbled with some microcontroller projects. I found both to be too big, ie couldn't find a library suitably small, either compiled size or memory requirements or both. So I ended up with JSON for those due to that. Using a SAX-like parser I could avoid dynamic allocations entirely (or close enough). Whaa? I wrote an MP implementation specifically for this use case: https://github.com/camgunz/cmp https://github.com/camgunz/cmp. JSON parsing terrifies me; there was some table of tons of JSON (de)serializers with all their weirdo bugs that I never would've thought of. There are probably pretty good test suites now though? I've never looked.

> I wrote an MP implementation specifically for this use case Perhaps I missed that, can't recall. Will definitely try (again) tho, looks very promising. As for parsing JSON, the upside is that's its trivial to debug over serial, both viewing and sending, and in my case I could assume limited shenanigans and fail hard if there were issues.
