Poetry gRPC plugin

A Poetry plugin to run the Protocol Buffers compiler with gRPC support.

Installing the plugin

Requires Poetry version 1.2.0 or above

poetry self add poetry-grpc-plugin

Usage

To run it manually:

poetry help protoc

Usage:
  protoc [options]

Options:
      --proto_path[=PROTO_PATH]             Base path for protobuf resources. [default: "<module_name>"]
      --python_out[=PYTHON_OUT]             Output path for generated protobuf wrappers. [default: "."]
      --grpc_python_out[=GRPC_PYTHON_OUT]   Output path for generated gRPC wrappers. Defaults to same path as python_out.
      --mypy_out[=MYPY_OUT]                 Output path for mypy type information for generated protobuf wrappers. Defaults to same path as python_out.
      --mypy_grpc_out[=MYPY_GRPC_OUT]       Output path for mypy type information for generated gRPC wrappers. Defaults to same path as grpc_python_out.
      --venv_proto_paths[=VENV_PROTO_PATHS] Additional protobuf resources paths, from the plugin's venv. Defaults to None.
      ...

Run on poetry update

[tool.poetry-grpc-plugin]

Additional config

[tool.poetry-grpc-plugin]
proto_path = "protos"               # Defaults to module name
python_out = "."                    # Defaults to .
venv_proto_paths = ["google/type"]  # Defaults to None

Settings in pyproject.toml will be used as defaults for manual execution with poetry protoc.

Using venv_proto_paths, one can import additional protos from packages installed in the same virtual environment as this plugin. For example:

pipx inject poetry googleapis-common-protos

[tool.poetry-grpc-plugin]
...
venv_proto_paths = ["google/type"]  # Defaults to None

Then in your proto file you can do:

import "latlng.proto";
