Generate language specific interfaces from proto file

Python gRPC Server (./python):

python -m grpc_tools.protoc -I. --python_out=./python --grpc_python_out=./python nltk_service.proto
python -m nltk.downloader stopwords

Go gRPC client (./golang):

protoc -I. nltk_service.proto --go_out=plugins=grpc:golang

How to run

Terminal 1 (python server):

brew install python
pip3 install virtualenv
virtualenv -p python3 .venv
pip install -r requirements.txt
source .venv/bin/activate
python python/server.py

Terminal 2 (Go client):

cd golang
go run client.go

IDE config

IntelliJ

• Mark python directory as "Sources root" (right click directory)
• Enable Go modules (vgo) integration

VSCode

• Import golang directory as a new folder to workspace in order for go-modules to work.
