Re: [protobuf] How to generate google.protobuf.Type object from a file

Yes, I agree that we should update the docs. I'm working on changing the
wording to say that the type server functionality is an optional feature
that one might choose to set up.

I've heard this a couple of times before, that the type server stuff was
abandoned. Could the docs be updated to reflect this? They still indicate
that type definitions will be downloadable from servers via the type URL.

Re: [protobuf] How to generate google.protobuf.Type object from a file

2017-10-20 Thread Josh Humphries 
FWIW, I've implemented this logic in Go in a library called protoreflect,
with the intention that it could be used for the type server functionality,
as documented.

Take a look at the methods MessageAsPType and EnumAsPType in MessageRegistry:

[protobuf] How to generate google.protobuf.Type object from a file

2017-10-19 Thread pradeepg26 
Hi All,

The documentation for google.protobuf.Any says that an HTTP GET on the URL 
should return a Type object in binary. However, I can't find any 
documentation on how create a Type object from a protobuf definition file. 
Given a compiled Message, how can I get a Type?

Thanks,
Pradeep
