Some plugins (e.g., flake8-future-import) report errors for empty
files. Those plugins default to reporting the line number as 1 which
caused earlier versions of Flake8 3.0 beta to crash on an IndexError
Closes#157
When flake8's config is in setup.cfg, setuptools attempts to set those
options on the command instance. If they don't exist, it fails early
complaining that a specific option does not exist.
This adds this back and does it better than the Flake8 2.x version.
Closes#163
On Flake8 2.x we added the information about the implementation,
version, and operating system to the --version output to make helping
users easier. In short they can pretty simply just give us the output
from
flake8 --version
And we can get a lot of the information that we need.
Previously, pycodestyle never introspected the argument names for
classes except to require that ``tree`` be an argument it could pass.
For Flake8 3.0, we lifted that restriction, but old plugins seem to
have cargo-culted their __init__ signature to be
def __init__(self, tree, builtins=None):
For some yet unknown reason. This was causing an AttributeError. By
updating flake8.utils.parameters_for to return a dictionary that
indicates whether the parameter is required or not, we can side-step
this by simply ignoring the parameter if it has a default value and
we cannot provide it.
Closes#151
Previously the --select was only ever populated to E,F,W,C and so
plugins would not be reported when not off-by-default. This adds a
tiny shim so that we enable plugins that are not off-by-default and
:x

Previously Flake8 parsed both
max-line-length = 110
And
max_line_length = 110
From the config file without issue. When we updated our logic, I forgot
to test for that and we lost that behaviour temporarily.
Closes#152
If somebody explicitly has a `.flake8` file, presumably they intend to
put flake8 configuration in it, so prefer it to the generic `setup.cfg`
and `tox.ini` from pycodestyle.
