Invalid syntax error in generated .pyi file

Hey! I’ve started using your plugin, and it’s working to an extent that the type hints are picked up by my IDE, which is helpful.

When trying to run mypy on the command line I get this error however:

com/fish/time/time_range_pb2.pyi:45: error: invalid syntax

The relevant lines:

 42 class TimeRange(google___protobuf___message___Message):
 43 
 44     @property
 45     def from(self) -> google___protobuf___timestamp_pb2___Timestamp: ...
 46 

I’m using this command line to check the types:

mypy --ignore-missing-imports --python-version 3.7 --namespace-packages --check-untyped-defs -p fish

where the com and fish directories reside inside the same directory, and fish is importing protobufs from com.

Before adding the --namespace-packages mypy did finish, but it didn’t seem like it took the types of the protobufs into account.

The protobufs are generated by

python3 -m grpc_tools.protoc -I ./proto --python_out=. --mypy_out=. --grpc_python_out=. ./proto/com/fish/*/*.proto

mypy version 0.701, Python 3.7.3

Any ideas?

#91 should solve it!

woops! It appears to be missing from https://github.com/dropbox/mypy-protobuf/blob/master/python/protoc-gen-mypy#L44

Comparing to https://www.programiz.com/python-programming/keyword-list - it’s the only one missing. Going to go ahead and add it and kick a version of mypy-protobuf! Thanks for the catch!
