BTW: I’ve been using

tox

for the last ~10 years and

poetry

for the last 2 or 3. I need to figure out how to use Pants with these two tools.

We really like both projects too! In fact, @steep-breakfast-98857 wrote a blog last week about the new Poetry support he added recently to Pants 2.6 https://blog.pantsbuild.org/poetry-support-for-pants-2-6/ Re tox, I'm honestly not sure the best way to integrate there and am not very familiar with folks trying that out. Happy to talk things through though if still using tox is important to you
