Python Betterproto Versions Save

Clean, modern, Python 3.6+ code generator & library for Protobuf 3 and async gRPC

v.2.0.0b6

11 months ago

Enhancements

  • Breaking: the minimum Python version has been bumped to 3.7 #444

  • Support generating Pydantic dataclasses. Pydantic dataclasses are are drop-in replacement for dataclasses in the standard library that additionally supports validation. Pass --python_betterproto_opt=pydantic_dataclasses to enable this feature. Refer to #406 and README.md for more information.

  • Added support for @generated marker #382

  • Pull down the include_default_values argument to to_json() #405

  • Pythonize input_type name in py_input_message #436

  • Widen from_dict() to accept any Mapping #451

  • Replace pkg_resources with importlib #462

Bug Fixes

  • Fix typechecker compatibility checks in server streaming methods #413
  • Fix "empty-valued" repeated fields not being serialised #417
  • Fix dict encoding for timezone-aware datetimes #468
  • Fix to_pydict() serialization for optional fields #495
  • Handle empty value objects properly #481

Thank you to all the contributors to this release and everyone for being so patient with its release.

v2.0.0b5

1 year ago

Enhancements

  • Breaking: Client and Service Stubs no longer pack and unpack the input message fields as parameters #331:

    Update your client calls and server handlers as follows:

    Clients before:

    response = await service.echo(value="hello", extra_times=1)

    Clients after:

    response = await service.echo(EchoRequest(value="hello", extra_times=1))

    Servers before:

    async def echo(self, value: str, extra_times: int) -> EchoResponse: ...

    Servers after:

    async def echo(self, echo_request: EchoRequest) -> EchoResponse:
    # Use echo_request.value
    # Use echo_request.extra_times
    ...

  • Format field comments also as docstrings #304
