Recursive pyupgrade option

[dsaxton]

Very cool project @asottile! I was curious if there was a way to run pyupgrade on whole directories or projects, and if not whether this might be a helpful feature to add? For instance have pyupgrade -r some_directory run recursively on the directory, or even drop the -r and let the recursive part be implied?

Thanks for building this!

pre-commit run pyupgrade --all-files or shell globs pyupgrade **/*.py

I don't think that this is a sufficient solution, because now you are forcing the user to use pre-commit instead of simply using Pyupgrade as a standalone tool.

For instance, I would love to add Pyupgrade as one of the default tools run by Statue, but the absence of the ability to run on directories is the only thing preventing me from doing it.

As I've shown in #344 , Implementation of this ability is quite easy and I hope you reconsider.
