Code Standards

Our older repositories were just checked with flake8.

We are now moving to checking all repositories with flake8, black and isort.

Note black will only work on Python 3.6+ so if the repository supports older version of Python, tricks will need to be used to make sure it only installs on 3.6+.

There are some config files we need.

isort.cfg should be:

# From https://black.readthedocs.io/en/stable/the_black_code_style.html?highlight=isort#how-black-wraps-lines
[settings]
multi_line_output=3
include_trailing_comma=True
force_grid_wrap=0
use_parentheses=True
line_length=88

setup.cfg should be:

[flake8]
# Ignore style checking, because black does this for us
ignore = E,W

.Travis should have lines to run isort, black and flake8.

• black --check .py /

• isort --check-only --recursive .py /

• flake8
