Hello everyone, I have a couple of micro-services, and each has couple of proto files. It's common for one micro-service proto file to reference another service proto file using import like so:
import "google/protobuf/struct.proto"; import "myService/v1/message.proto"; import "myOtherService/v2/parser.proto"; We use a Gradle script that's responsible on creating the folder structure and fetch all proto dependencies from different git repositories. So in the example above the Gradle script will output will be a folder named `google/protobuff`, `myServicev1/v1` and `myOtherService/v2` - each of the folders will hold the proto files needed. Once the folder structure is OK, I can use `protoc` to generate the Python code. Here's where the problem begins. The generated `_pb2` code import modules based on the folder structure. So the import inside the `_pb2` file will look like so: from google.protobuf import struct_pb2 as google_dot_protobuf_dot_struct__pb2 That's a relative path import, and it means that in order for my Python program to work, the root folder where the Python script running from, should have the `google/protobuff` folder for this import to work.Now because I have multiple micro-services, I don't appreciated the fact I have to add 3 new folders in my main Python project (it's even more painful when you create a Pip package). What I was hoping to do is to open a directory called `proto`, and add all that directory structure into it - but because imports are relative, this won't work. I tried to to play with couple of `protoc` options like `PROTO_PATH`, or run `protoc` from a parent directory, so the `_pb2` files will get created with a different relative path I can work with like so: from proto.google.protobuf import struct_pb2 as google_dot_protobuf_dot_struct__pb2 But I wasn't able to do so. A dirty option would be adding the `proto` folder into my `PYTHONPATH`. It's not pretty, and I'm guessing there is probably a simple solution for that I'm missing with `protoc`.
