Look's interesting, but I hesitate to use a Python formatting tool whose own code runs counter to well accepted Python stylistic guidelines -- namely "Use 4 spaces per indentation level." (https://www.python.org/dev/peps/pep-0008/#indentation)
Without some examples from the author (or sinking time into installing/playing with it) it's pretty hard for me to tell what it's actually going to do with the code.
AutoPEP8 will generally intelligently pick between a standard hanging indent, a deep hanging indent, and an aligned indent. Does this not do so?
Edit: oh, I see. The author's code uses two spaces. Heh.
yapf is developed using an internal Google coding style. Please don't hold it against the project :-) Once you get used to the style, the code of yapf is very consistent in terms of style (it was formatted with yapf itself!) and should be easy to understand & work with.
It does support the PEP8 style out of the box, however.
^ that notes that you're referring to an internal style guide. Their external guide (which is the one I'd think I'd be following) is more PEP8-y.
You might consider renaming your "google" to "google-internal." But since Chromium appears to be the remaining big external-facing project using the old internal style, I'd suggest chromium vs. google vs. pep8. That would make more sense to the wider audience.
