not yet, but it should be reasonably easy to add,
i suspect its a nice item start contributing,
if you are interested, please drop by in the irc channel #pylib on freenode

Is this possible?

[obestwalter]

Closing this as it is very old and things have moved a lot since then.

I've bumped into this today, apparently this is needed so that the vagrant file you added can run on Windows 😲 we should probably reopen it to make this happen for ourselves (development purpose)

The need of this always copy is optional on the invoking environment, so this should be either a tox cli argument, or taken from the env; what do you guys think?

@gaborbernat thanks for trying this. Let's reopen this then.

I have no opinion about from where to fetch it yet. Is there some "prior art" in the code, where we could take inspiration from for this kind of problem?

[obestwalter]

just realized that @asottile added this already as a cli arg for 2.6, so I guess we can close this as resolved?

[asottile]

heh, I don't want to take credit for something I didn't do, here's the changeset thanks to @igordcard

https://github.com/tox-dev/tox/pull/434

[obestwalter]

ups - sorry, I had associated that with you for whatever reason - anyway you did other great things recently :)

Thanks to @igordcard then 🎉

[gaborbernat]

yeah, it works via that :+1:

[obestwalter]

fixed since 2.6 - see http://tox.readthedocs.io/en/latest/config.html?highlight=alwayscopy#confval-alwayscopy=True|False

Use the flag fo systems that need it.
