Part of the 2.0 redesign (in my mind) was to open up the avenue of
having an API as part of Flake8 to allow people to do fun stuff with
it. Unfortunately it seems we did not open it enough. Take a look at
this issue on pep8: https://github.com/jcrocholl/pep8/pull/181. It's
an odd request but it makes some sense to allow people to pass their
own everything to Flake8 using our tools. I have a few ideas about how
to make this easier for others to extend, but I'm not sure if they're
overkill or not.
The first is to have main create a StyleGuide and pass it to a
function that does the rest of main with the StyleGuide that was
passed in. This allows people to use `get_style_guide` to retrieve a
StyleGuide with their own options and do all kinds of wonderful
(horrible) things to it and then uses it to execute main. The issue
with this is they could ostensibly remove options or methods that main
currently relies on (and therefore this other function would rely on).
The second is not much different but would allow main to directly take
**kwargs and merge those with what we pass to `get_style_guide` (this
is actually Florent's idea).
The former feels more flexible and yet dangerous, the other seems less
flexible but almost flexible enough for what seems to be the current
Any and all opinions are welcome.
Anyone with Mercurial extension experience, please contact me separately. ;-)
