Features

Note: At this stage, the project is highly experimental and hacky, so don’t expect stable APIs and tons of features!

Functions are basically orchestrated using ASAM MCD-2MC (A2L) files.

Some examples include (not necessarily in a working condition yet):

• Create calibration data files (ASAM CDF) from XCP slaves or HEX files.

• Setup dynamic DAQs.

• High-level API to create MDF files.

Migration & Compatibility

• Prefer public imports from asamint.api (Calibration/OfflineCalibration/OnlineCalibration, ParameterCache, measurement helpers, finalize_daq_csv, config snapshots) instead of deep package paths; consume pyxcp/pya2l/asammdf/objutils only through their adapters.

• CLI/config: use asamint.cmdline.finalize_daq_csv for DAQ CSV → CSV/HDF5 finalization; configuration is traitlets-based (asamint.config) with Path and configure_logging defaults.

• Fixtures stay under tests/ (A2L/HEX/MSRSW, DAQ CSV/HDF5); external-facing formats (CDF/MDF/HDF5) remain compatible, with new helpers added behind existing facades.

• When migrating older code, update imports, replace direct adapter usage, and validate with poetry run pytest plus poetry run ruff check ..

API Stability & Deprecation

• The stable public surface is exported from asamint.api. Prefer these names in application code.

• Renamed or removed API names are kept as deprecated aliases in asamint.api and emit DeprecationWarning when accessed.

• Deprecated aliases include a removal version in asamint.api._DEPRECATED_ALIASES; remove legacy usage before that version.

• If you need a new alias for migration, add it to asamint.api._DEPRECATED_ALIASES and cover it with a small test.

Please refer to examples directory.

Measurement Formats & Registry

• CSV, HDF5, and MDF handling lives under asamint.measurement.{csv,hdf5,mdf} and is registered in the measurement format registry; thin shims stay at asamint.hdf5/asamint.mdf for compatibility.

• Custom backends can be registered without touching core code. Example (InfluxDB placeholder):

from pathlib import Path
from asamint.adapters.measurement import MeasurementFormat, register_measurement_format
from asamint import measurement

def persist_influx(*, data, units=None, project_meta=None, output_path: str | Path | None = None, **kwargs):
    return measurement.RunResult(
        mdf_path=None,
        csv_path=None,
        hdf5_path=str(output_path) if output_path else None,
        signals={},
        timebases=None,
    )

register_measurement_format(
    MeasurementFormat(
        name="INFLUX",
        persist=persist_influx,
        description="Persist measurements to InfluxDB",
        default_extension=".influx",
    )
)
