# tinker_cookbook.utils.make_deprecated_module_getattr

### [**tinker_cookbook.utils.make_deprecated_module_getattr**](https://github.com/thinking-machines-lab/tinker-cookbook/blob/main/tinker_cookbook/utils/deprecation.py#L198)(*module_name*, *attrs*)

Create a `__getattr__` function for deprecating module-level attributes.

Returns a function suitable for assigning to `__getattr__` at module scope. When an old attribute name is accessed, it emits a deprecation warning and transparently returns the new object.

**Parameters:**

- [**module_name**](https://github.com/thinking-machines-lab/tinker-cookbook/blob/main/tinker_cookbook/utils/deprecation.py#L199) (*str*) – `__name__` of the module defining `__getattr__`.
- [**attrs**](https://github.com/thinking-machines-lab/tinker-cookbook/blob/main/tinker_cookbook/utils/deprecation.py#L200) (*dict\[str, tuple[str, str | None]\]*) – Mapping of `{old_name: (dotted_path_to_new, removal_version)}`. *dotted_path_to_new* is `"package.module.NewName"` and will be imported and returned. *removal_version* may be `None`.

**Returns:** A `__getattr__` function.

```python
# In mymodule/__init__.py
__getattr__ = make_deprecated_module_getattr(
__name__,
{"OldThing": ("mymodule.new_place.NewThing", "0.20.0")},
)
```
