I'm on the fence. I think I'd be okay with this if it was done at something like a 3.0 release, which is what it is slated for in the issues. Doing so before that seems like it will cause headaches for everyone with an active fork. What I'm more worried about is how it is handled moving forward. Is it reasonable to require all contributors to run with pyflakes or flake8 (http://pypi.python.org/pypi/flake8) with an option that all failures stop the commit? Or do we just ask that they do so, let Jenkins tell us if they screwed up, and ask them to fix it?
I'm also fine with waiting for a 3.0 release, which I would like to have out by the end of this calendar year. An overall eyes-on-code initiative would fit with that. Unfortunately this is the kind of activity that fits much better with coordinated development, either remotely through some kind of audio video chat, or in person around a table. As for mandating people do it, I think having Jenkins complain and then either encouraging compliance or manually fixing minor things would be fine. Right now we are still setting the standards for how to develop; we can strive to set a good example and encourage those practices by others. Mentoring during early development is a good idea, as well. We actually have style guides which aren't commonly read, but if we are serious about improving the code smell we can try to make this a bigger priority when evaluating pull requests, suggesting projects, going over diffs, etc. -Matt
Anyways, I guess I'm a +0.

I'm in favor of this, too. There's a good amount of code written by myself that does not comply but has not gotten changed because I didn't want to break old scripts. I wouldn't mind fixing it all as a part of one big effort.

I am broadly in favor of using PEP-8 standards. (As long as we're on the topic, Kacper also had a great suggestion that we run static analysis like pyflakes.) Our oldest open ticket, from pre-BB migration, is about PEP-8.
https://bitbucket.org/yt_analysis/yt/issue/39/follow-pep8-style-conventions
Fixing line length and so on I am fine with being done automatically with one of those tools. For changing method names, which I am also in favor of, we should either identify them and fix them manually or use a refactoring tool like rope or bicycle repair man.
For all of this I would like to do it in one go, with a single bandaid to rip off, and beforehand consolidate all extant branches. RIght now we have a couple things under active development; we could do this relatively soon, but I think we need some kind of coordinated effort to merge relatively quickly back into those branches to make sure we don't just cause a ton of merge conflicts. Here's my proposal:
* Make the change to main branch * Merge those into geometry, rockstar, volume rendering * Add pyflakes and/or pep8 checks to Jenkins
Thoughts?

Hi Stephen.
Not sure about all of the pep8 suggestions, but I think this is important. Some are purely style/consistency, like whitespace before ')'. Some would hold yt back from Python3 in the future, like .has_key() is deprecated, use 'in'.
Do you think it will be enough to autopep and run the full tests? I have no idea about coverage, but it would be great to fix some of these.
Best, Casey

Hi all,
while vegging out in front of the TV, I've been playing with a pep8 checker (http://pypi.python.org/pypi/pep8), and I get the statistics below for all the *.py files in yt. How much do we care about this stuff? There are automatic tools (http://pypi.python.org/pypi/autopep8/0.3) but I don't know if we can trust them. Thoughts?
