The last time I looked at upb, it only supported parsing, which was a deal-breaker. Have you implemented serializing since then? It's hard to tell from the git log, which is mostly "dump from google internal sources XX-YY-ZZZZ".

I'm very excited about upb! Thanks for your work on it over the years. Do you have any tasks that an outside contributor could help with?

Thanks!

Still no serialization, sorry. This is getting close to being my top priority though. It's a hard problem to design the kind of generic visitor I want while being speed-competitive with the fastest stuff that's out there.

Probably can't use a lot of outside help, but thanks for asking. What's taking so long is a very intense process of refining the design. I am often reminded of this bit from "Worse is Better":

"The right thing takes forever to design, but it is quite small at every point along the way."

This is exactly the approach I am taking. It's taken forever to design, but over time it becomes more and more capable without the core growing in size very much. I hope that this intensive design work will pay off soon.

Thanks for your interest and I hope to soon be able to reward it with a highly compelling parsing/serialization experience!

Awesome, looking forward to that day :). Keep up the great work.
