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 or check command yet for a dry-run or linting.
