No way to specify python_gapic_opt flag with py_gapic_library rule #390
Description
We need to replicate the following protoc invocation from Bazel rule py_gapic_library. In particular, there's no current way to set --python_gapic_opt to the desired value below:
protoc google/ads/googleads/${VERSION}/**/*.proto \
--proto_path="${COMMON_PROTOS_PATH}" \
--proto_path=. \
--python_gapic_out=${OUTPUT_DIR} \
--plugin=${GAPIC_GENERATOR_PATH}/gapic/cli/generate.py=python_gapic \
--python_gapic_opt="old-naming,lazy-import,python-gapic-name=${GAPIC_NAME},python-gapic-templates=${GAPIC_GENERATOR_PATH}/gapic/ads-template"
where one var is custom:
GAPIC_NAME is googleads.
And the other vars are what you'd expect:
COMMON_PROTOS_PATH is api-common-protos dependencies
GAPIC_GENERATOR_PATH is root of gapic-generator-python
