Full disclosure, i was the one who suggested using .flake8 so this on me, but i figured out that we can instead use setup.cfg, which we are already using for versioneer. So I'm requesting that we update setup.cfg to look like this

[versioneer]
VCS = git
style = pep440
versionfile_source = arkouda/_version.py
tag_prefix =
parentdir_prefix = arkouda-

[isort]
profile = black

[flake8]
max-line-length = 88
extend-ignore = E203

We can still git ignore .flake8 in case anyone wants to override our default

@pierce314159 - setup.cfg has been updated.

@pierce314159 - we may want to update max line length. At least in my editor, it is showing lines as too long that aren't showing as long at all. Based on what I am seeing I would recommend setting it at 110. Though, I would like to see if maybe my editor is just wider than others or something.

yeah this is one of the few cases where i don't like PEP 8. I'm with you, i prefer longer lines for readability

Just so everyone is aware, black already exceeds PEP 8's recommendation of 79 characters per line with it's default of 88 characters

It appears like line length is one of the only configurable things in black with the --line-length flag. I don't know if this can be set to higher than 88 or only lower tho. But i'm down for a more sensible default as long as we're all consistent about it since we all have large monitors.... and i love my long one liners :)

I updated the max_line_length to 105. This looks like it is a good setting. This requires black to be run as black --line-length 105 <filename>. If using black as an external tool in pycharm this can be set to run automatically.
