If TOX_WORK_DIR is set, honor it.

[jaraco]

This issue is a revived feature request of #20.

In summary, I'd like tox to honor TOX_WORK_DIR as the default tox.toxworkdir if set, similar to the effect of adding

toxworkdir={env:TOX_WORK_DIR:.tox}

to the tox.ini file.

In #1653, I attempted to implement the feature, but failed to land it before resolving all of the issues.

I'd still like to see this feature implemented so that I don't have to carry this config in every tox file.

Isn't this already working?

❯ env TOX_WORK_DIR=.tox4 tox c -e py311 -k env_dir
[testenv:py311]
env_dir = /Users/bgabor8/git/github/tox/.tox4/py311
~/git/github/tox on  work-dir [$?⇡]
❯ env TOX_WORK_DIR=.tox3 tox c -e py311 -k env_dir
[testenv:py311]
env_dir = /Users/bgabor8/git/github/tox/.tox3/py311

Yes! It does work.

It seems to have been fixed in the 4.0.0a2, so was fixed in the rewrite.

That's fantastic news. I'm a little ashamed I didn't think to re-check the assumption.

Would you like the bounty?

I've been extremely impressed with the reliability and design of tox 4. Thanks for doing all that work.
