Sorry, I don't understand this issue. Has it anything to do with the field order at encode time? I'm using two libraries (java and this one) to create the same protobuf and getting different ordering.

@diegonc Hi, protobuf's spec do not define the order of encoded bytes. So it's valid to just have random order. if you really need specific order, you could write message yourself using pb.buffer low level routines.

Yeah, it's valid for parser but encoders should sort them by number according to the link posted above.

Anyway, I'm trying in the gist below to use pb.buffer but I'm no sure how to send fields and following Lpb_encode is getting hard as it uses things that don't seem to be available in Lua. Can you help me fill the gaps? Thanks
