Makes typed arguments Optional when the default argument is None
Project description
auto-optional: Makes typed arguments Optional when the default argument is None.
Documentation: auto-optional.daanluttik.nl
Source Code: github.com/luttik/auto-optional
Purpose
The basic purpose of auto-optional is ensuring that whenever a default argument is None
the type annotation is Optional.
For example:
def foo(bar: str = None):
...
Would turn into
from typing import Optional
def foo(bar: Optional[str] = None):
...
Install
Install with pip install auto-optional
.
Run
After installing you can run auto-optional using auto-optional [path]
(path is an optional argument).
Properties
- Existing imports are reused.
import as
statements are properly handled.
Things of note
For all these points I welcome pull-requests.
- There is no exclude (for file patterns) option yet
- There is no ignore (for code lines) option yet
- Code is aways read and written as
UTF-8
(which is accurate most of the time). - There is no
diff
orcheck
command yet for a dry-run or linting.
