Consider a `pyproject.toml` option for restoration of existing `version.py` behavior

[kory]

In setuptools-scm v 10.x, version.py is no longer generated in source. An environment variable is offered as an alternative to restore the old behavior.

We often mix installing a built wheel with running scripts from the root of our repository. Python's sys.path will prioritize the local package inside the repository root, which no longer has _version.py, resulting in failures.

It is difficult for us to inform all users of our source code that an environment variable is now needed for many of our workflows to continue functioning correctly.

Please consider adding a pyproject.toml option to restore the old behavior. This would help minimize disruption for projects that were relying heavily on the previous behavior.

the old behaviour will be partially restored - but eventually the version file generation should affect only editable/normal installs - not source trees

i'll create a timeline for this

ps - the release was yanked so the immediate problem should be resolved

Thhe current release restores the writing

The next phase out will be more
nuanced
