Feature Request

I am trying to figure out what would be the best way to combine poetry's dependency management with tox. I need to configure multiple environments for formatting, linting, testing, etc. and each of those environments has a different list of development dependencies. I think I could make it work by defining groups for dependencies but would it not be simpler to just be able to create any dynamic filter within tox, so that poetry does not need to be aware of those different groups, just that the dependencies are only for development?

This is why I suggest adding filtering functionality to poetry export so that one could do:

poetry export --only dev --filter 'pytest,pytest-*'

So that then tox's default handling of dependencies (via pip) can rely on dynamically generated locked dependencies' lists.

Start by reviewing the existing poetry export command and its --only behavior, then examine how tox consumes dependency lists through pip. Define the filtering syntax and supported matching behavior before implementation. Done means an export can dynamically select matching development dependencies for tox environments and has coverage for the requested example.
