current-data-py

Current Data protobuf messages and schema metadata. Requires Python 3.9+.

pip install current-data-py

from current_data_py import SCHEMA_TO_CLASS, descriptor_set, topic_metadata
from current_data_py.schema import Pose

message = Pose()
message.position.y = 1.0
metadata = topic_metadata(Pose)
decoded = SCHEMA_TO_CLASS[metadata["schema_name"]].FromString(message.SerializeToString())

TD examples write/read a Pose on /head/pose/command:

python -m current_data_py.write_td example.td
python -m current_data_py.read_td example.td

Development and releases

Packaging configuration lives in current_data_py/. Generated messages live only in the repository's proto_gen/python/msg. Regenerate them using the existing proto/generate.sh workflow after changing proto/msg. The build reads those files and adjusts their Python imports in the build directory, placing them under current_data_py._proto in the wheel. It does not modify or duplicate generated sources in the checkout. The source distribution includes the original generated files so it can also build without protoc. Installation requires neither the repository nor protoc.

cd current_data_py  # from the repository root
python -m pip install build twine
python -m build
python -m twine check dist/*
python tests/check_distribution.py

Artifacts are written to current_data_py/dist/. The build adds the shared protobuf inputs to the source archive without copying them into this directory.

For development, use a regular pip install . and run from outside the checkout; reinstall after changes. Editable installs are not supported by this build step.

Install the wheel in a fresh environment and run python /absolute/path/to/current_data_py/tests/check_package.py from outside the repository. Use a clean dist for each release and increment the version in pyproject.toml. Confirm the package name, license and supported Python versions before publishing. No license has been selected yet.

python -m twine upload --repository testpypi dist/*
# After validating the test release:
python -m twine upload dist/*
