This is useful for preparing the current environment for ``tox --current-env``.

It is possible to use the two printing options together, as long as the ``FILE`` is different.
``tox --print-dependency-groups-to=FILE``
Instead of running any ``commands``, simply prints the names of the
`declared dependency_groups <https://tox.wiki/en/latest/config.html#dependency_groups>`_
in ``dependency_groups`` to the specified ``FILE``.
This is useful for preparing the current environment for ``tox --current-env``.
Use ``-`` for ``FILE`` to print to standard output.
This option only exists with tox 4 and requires at least tox 4.22.
It is possible to use the three printing options together, as long as the ``FILE`` is different.
Invoking ``tox`` without any of the above options should behave as regular ``tox`` invocation without this plugin.
Any deviation from this behavior is considered a bug.

- The plugin does not check the requested Python version nor the environment name.
If you let it run for multiple environments they'll all use the same Python.
- Deprecated ``--print-deps-only`` option is no longer available.
- The ``--print-dependency-groups-to`` is only defined on tox 4.
