Loaders

Functions to load JSON or XML files for conversion into authorityspoke objects.

Will usually hand off data to the io.readers module to create authorityspoke objects.

authorityspoke.io.loaders.load_holdings(filename=None, directory=None, filepath=None)

Load list of records from YAML or JSON to create Holdings with text selectors.

Parameters:

filename (Optional[str]) – the name of the JSON file to look in for Holding data in the format that lists mentioned_factors followed by a list of holdings.
directory (Optional[Path]) – the path of the directory containing the JSON file.
filepath (Optional[Path]) – Complete path to the XML file representing the Code, including filename.

Return type:

List[Dict[str, Union[Dict[str, Union[Dict[str, Sequence[Dict[str, Union[Dict[str, Union[str, bool]], Sequence[Any], str, bool]]]], Sequence[RawEnactment], str, bool]], str, bool]]]

Returns:

a list of Holdings from a JSON file in the example_data/holdings subdirectory, from a JSON file.

authorityspoke.io.loaders.read_holdings_from_file(filename=None, directory=None, filepath=None, client=None)

Read holdings from a file.

Parameters:

filename (Optional[str]) – The name of the input JSON file.
directory (Optional[Path]) – The directory where the input JSON file is located.
filepath (Optional[Path]) – Complete path to the JSON file representing the Opinion, including filename.
client (Optional[Client]) – The client with an API key to download Enactments mentioned in the holding.

Return type:

List[Holding]

authorityspoke.io.loaders.read_anchored_holdings_from_file(filename=None, directory=None, filepath=None, client=None)

Read holdings from file, with Opinion text anchors for holdings and factors.

This function can accept a file containing authorityspoke.holdings.Holding summaries in the YAML format that may contain abbreviations and expandable named entities.

In the example below, a FakeClient is used to add fields to Enactments in the Holding objects, to avoid using the network or making API calls. The real LegisClient class would also have worked (with an appropriate API key). :rtype: AnchoredHoldings

>>> from authorityspoke.io.fake_enactments import FakeClient
>>> fake_client = FakeClient.from_file("usc.json")
>>> filepath = filepaths.make_filepath(filename="holding_mazza_alaluf.yaml")
>>> with open(filepath, "r") as f:
...     yaml.safe_load(f)
