neon3-sdk

Python SDK for the Neon3 neon3.rpc control plane.

cd packages/python-sdk
pip install -e .
python -m neon3_sdk calculator

Tests and deterministic scenario:

python -m unittest discover -s tests -v
python -m neon3_sdk calculator --once

Event subscriptions

The SDK also exposes the canonical neon3.event stream. A WGPU window owner publishes ui.file_drop.accepted for OS file drops; same-machine tools can subscribe without implementing a second transport:

from neon3_sdk import EventClient

events = EventClient.connect("127.0.0.1:39101").subscribe(
    name="ui.file_drop.accepted"
)
with events:
    for image in events.file_drops():
        print(image.source_path)

When --neon-root is omitted, the command uses the SDK-local release directory. Set NEON_ROOT or pass --neon-root <path> only to override it. Runtime clients can select a checkout profile with RuntimeConfig(profile="debug") or RuntimeConfig(profile="release"); auto preserves the release-first default.
