# Spec Classes This is a small utility package that provides the `spec_cls` decorator that adds helper methods to allow users to mutate fields. ## Installation ```shell pip install spec-classes ``` ## Documentation There is not much in the way of standalone documentation, but everything is documented fairly thoroughly in the source code, or you can install it and the view the inline documentation using: ```python >>> from spec_classes import spec_class >>> help(spec_class) A class decorator that adds `with_<field>`, `transform_<field>` and `without_<field>` methods to a class in order to simplify the incremental building and mutating of specification objects. By default these methods return a new instance decorated class, with the appropriate field mutated. ... ``` ## Examples ```python @spec_class class UnkeyedSpec: nested_scalar: int = 1 nested_scalar2: str = 'original value' @spec_class(_key='key') class KeyedSpec: key: str = 'key' nested_scalar: int = 1 nested_scalar2: str = 'original value' @spec_class(_key='key') class Spec: key: str = None scalar: int = None list_values: List[int] = None dict_values: Dict[str, int] = None set_values: Set[str] = None spec: UnkeyedSpec = None spec_list_items: List[UnkeyedSpec] = None spec_dict_items: Dict[str, UnkeyedSpec] = None keyed_spec_list_items: List[KeyedSpec] = None keyed_spec_dict_items: Dict[str, KeyedSpec] = None recursive: Spec = None s = Spec() spec.with_scalar(3).with_spec_list_item('x').... ```
