a quick golang implementation of google pubsub subscriber for testing with the emulator.
it does one thing which is subscribing to a topic and receiving messages. ok, that's two.
this can be used to read message your application sends to the emulator. there is a python script for it but as I can play around with Go and do more things I make this one.
go install https://github.com/namp10010/gosub@latest PUBSUB_EMULATOR_HOST=localhost:8085 gosub -p project -t topic -s testsub
