euporie.core.config.DefaultNamespace

class euporie.core.config.DefaultNamespace(default_factory: Callable[[str], Any] | None = None, mapping_or_iterable: Mapping | Iterable[tuple[str, Any]] | None = None, /, **kwargs: Any)

A namespace that creates default values for undefined attributes using a factory function.

This class extends SimpleNamespace to provide automatic creation of default values when accessing undefined attributes, similar to collections.defaultdict but for object attributes.

_factory

A callable that generates default values for undefined attributes. If None, AttributeError will be raised for undefined attributes.

Examples

>>> # Create namespace with list factory
>>> ns = DefaultNamespace(default_factory=list)
>>> ns.numbers.append(1)  # Creates new list automatically
>>> ns.numbers
[1]

>>> # Create with initial values
>>> ns = DefaultNamespace(default_factory=int, x=1, y=2)
>>> ns.x
1
>>> ns.z  # Creates new int (0) automatically
