I would like to release a python package for the protobuf message set. The protobuf ( protoc
) compiler creates a python library that does not actually define types / classes typical meaning, but rather constructs them dynamically. Is there any way to hint that the members and fields of these classes?
For example, consider the following simple protobuf message specification:
message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3;
}
The compiler generates the following long bunch of code:
# Generated by the protocol buffer compiler. DO NOT EDIT!
# source: test.proto
import sys
_b=sys.version_info[0]<3 and (lambda x:x) or (lambda x:x.encode('latin1'))

from google.protobuf import message as _message
from google.protobuf import reflection as _reflection
