Example of Virtualenv Discover Selection?

[lanshark]

What's the problem this feature will solve?

I would like to use either asdf or pyenv to run tests with multiple versions of python.

Describe the solution you'd like

Provide a decent example of the implementation of the python discovery process, which is extremely poorly documented.

Both the tox-asdf and tox-pyenv plugins no longer support version 4. The only extant implementation appears to be tox-pdm, but its not clear this implementation works in a similar manner.

Alternative Solutions

None - I have already forked both tox-asdf and tox-pyenv, and am willing to do the work to bring them up to support 4.0 - in fact, I have some parts of that work completed. But the discovery mechanism is not well documented.

Additional context

Any suggestions, or links to any package which supports the python virtualenv discovery mechanism would be helpful.

Have you considered virtualenv-pyenv?

It seems to replace the functionality of tox-pyenv, but works for virtualenvs outside of tox as well; you could probably depend on it in your tox environment by adding the plugin to the requires list
