def spec_from_signature(

    sig: Signature,
    include_defaults: bool = True,
    base: Type[BaseConfiguration] = BaseConfiguration
) -> Tuple[Type[BaseConfiguration], Dict[str, Any]]

[view_source]

Creates a SPEC on base base1 for a function fwith signaturesig`.

All the arguments in sig that are valid SPEC hints and have defaults will be part of the SPEC. Special markers for required SPEC fields dlt.secrets.value and dlt.config.value are parsed using module source code, which is a hack and will not work for modules not imported from a file.

The name of a SPEC type is inferred from qualname of f and type will refer to f module and is unique for a module. NOTE: the SPECS are cached in the module by using name as an id.

Return value is a tuple of SPEC and SPEC fields created from a sig.
