proto-topy 0.1.0

Yet another tool that compiles .proto strings and import the outcome Python modules.

A tool that

• takes a str containing protobuf messages definitions
• returns a types.ModuleType instance

It is useful for Python programs needing to parse protobuf messages without having to host .proto files in their code base.

Installation

pip install proto-topy

Usage example

import sys, os
from pathlib import Path
from distutils.spawn import find_executable
from proto_topy.entities import ProtoModule
from google.protobuf.timestamp_pb2 import Timestamp

protoc_path = Path(find_executable("protoc") or os.environ.get('PROTOC'))

source = """

    syntax = "proto3";
    import "google/protobuf/timestamp.proto";
    
    message Test5 {
        google.protobuf.Timestamp created = 1;
    }

"""

proto = ProtoModule(file_path=Path("test5.proto"), source=source).compiled(protoc_path)
sys.modules["test5"] = proto.py

assert isinstance(proto.py.Test5().created, Timestamp)
