Re: [protobuf] Re: python enum values option
I see, the problem is that you've created a copy of descriptor.proto and are
extending that rather than extending the original file.
To correctly extend descriptor.proto, you need to import it like:
import google/protobuf/descriptor.proto;
The path name is important, because it determines which module your
generated code imports and extends. You want it to import
google.protobuf.descriptor_pb2 (which is included in the protobuf library),
not your own local copy of descriptor_pb2.
Note that when you install protocol buffers, a copy of descriptor.proto is
placed in $PREFIX/include/google/protobuf (where $PREFIX is usually /usr or
/usr/local). So you should invoke protoc like:
protoc -I. -I/usr/include ooo.proto
This way ooo.proto will be able to import google/protobuf/descriptor.proto,
which protoc will find in /usr/include.

Kenton,
I didn't find how to attach file in the group discussion, so am replying to
you directly.
In attach you will find the source proto file, the generated *pb2.py files,
and the test program enum_test.py
I used: google protobuf 2.3.0 and proto compiler 2.3.0 win32 from here:
http://code.google.com/p/protobuf/downloads/list
The test output is:

Thnk you very much for support

That is strange. Can you provide a minimal but complete program that
reproduces this problem, so I can look at it?

Any ideas ? may be it is already solved in trunk version?
Thanks

I haven't checked that that's exactly correct, but it gives you an
idea. We
should probably improve this.

Hi, I'm stuck with getting the enum value option in Python. The proto

When I receive the Request message, I can access the 'error' field,
and its type is int, that's actually ok. But how can I get the
verbose_enum_value_option of 'error' field value ?
Thanks
p.s. The goal is to keep error types and their verbose error messages
in one place, available for every service in our project, so the
error
messages would've been identical.
