pyprotostuben 0.3.4

Generate Python MyPy stub modules from protobuf files.

pyprotostuben

Generate Python modules from protobuf files.

usage

pypi package

install with your favorite python package manager

pip install pyprotostuben

Then use protoc plugins to generate python code. See greeting examples for more info.

protoc plugins

protoc-gen-mypy-stub

Generates python stubs (*_pb2.pyi & *_pb2_grpc.pyi files which then used by MyPy type checker / IDE syntax highlits & suggestions).

features:

• choose message structure immutability / mutability
• choose async / sync grpc module stubs
• grpc servicer abstract methods have full signature (with appropriate type args in generics), thus it is easier to implement methods in IDE

plugin options:

• message-mutable -- add setters for fields, use mutable containers
• message-all-init-args-optional -- each field is optional in message constructor (even if field is not optional)
• grpc-sync -- use sync grpc stubs instead of grpc.aio module and async defs
• grpc-skip-servicer -- don't generate code for servicers
• grpc-skip-stub -- don't generate code for stubs
• no-parallel -- disable multiprocessing
• debug -- turn on plugin debugging

protoc-gen-brokrpc

Generates *_brokrpc.py modules for BrokRPC framework. This is similar to gRPC codegen (*_pb2_grpc.py modules).

plugin options:

• no-parallel -- disable multiprocessing
• debug -- turn on plugin debugging

protoc-gen-echo

Saves protoc plugin input to a file. Helps develop protoc plugins.

plugin options:

• format={raw|binary|json} (default = raw) -- specify output format
• dest={path} (default = request.json) -- specify file destination
