Project description
proto2obj
This Python library converts Protocol Buffers (Protobuf) messages into Python classes, mapping each message member to a class property. The main purpose of this library is to enable inheritance from Protobuf messages. Instead of inheriting directly from the Protobuf message (which is impossible), it inherits from a proxy class that shares the same data structure and can be converted back to Protobuf message data.
Installation
pip install proto2obj
Example of usage :
Example 1 :
from proto2obj import Proto2Obj
# msg is a protobuff message type
fake_msg_type = Proto2Obj(msg).convert()
#def convert(self,base = tuple() , attrs = dict()) :
# base = baseclasses , to generate the new type as drived from base classes
# attrs = extra static memebers assigned to new generated type
# get fields :
print(f"Message fields : {instance.__fields__}")
# get enums
print(f"Message enums : {instance.__enums__}")
# get nested types , they are converted also
print(f"Message nested types : {instance.__nested_types__}")
# the original protobuff message which is converted from
print(f"Message original protobuff message : {instance.__protobuf__}")
## create instance
instance = fake_msg_type(var = value , ....)
# assigne memebers like normal python object
instance.var = value2
# convert back to protobuff instance
msg_instance = instance.proto()
Example 2 :
from proto2obj import Proto2Obj
# msg is a protobuff message type
fake_msg_type = Proto2Obj(msg).convert()
class DrivedType(fake_msg_type) :
pass
instance = DrivedType(var = value , ....)
