Right, I guess I didn't explain why they don't work in this case. Generating .proto files from C++ headers is obviously the reverse of the normal sequence. In the PB method of versioning, the original .proto is written and deployed. The next version then writes an extension of the original. If

Protocol buffers are useful even if all users are using the same language. In fact, we used them in C++ for some time before anyone bothered writing Java and Python implementations. On Wed, Jan 7, 2009 at 3:43 PM, Alek Storm wrote: > > Mike, what exactly are you trying to accomplish? Do you ju

Mike, what exactly are you trying to accomplish? Do you just want to persist a C++ class? If so, you don't need to generate a .proto file, because other languages won't need to read it, and you know your own encoding layout. So you could still use the Protocol Buffers wire format. --~--~---

SWIG translates C/C++ APIs into other programming languages. Protocol Buffers is not a programming language, so I don't see the analogy. What would be the protocol buffer equivalent of a C function or a C++ class? On Wed, Jan 7, 2009 at 2:00 PM, mikesparr...@gmail.com < mikesparr...@gmail.com> w

Is there an existing convert that can take a header file and produce a .proto file? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Protocol Buffers" group. To post to this group, send email to protobuf@googlegroups.
