# -*- conf -*-
# flake8 settings for Spack.
#
# These exceptions are for Spack core files. We're slightly more lenient
# with packages.  See .flake8_packages for that.
#
# This is the only flake8 rule Spack violates somewhat flagrantly
# - E731: do not assign a lambda expression, use a def
#
# This is the only flake8 exception needed when using Black.
# - E203: white space around slice operators can be required, ignore : warn
#
# We still allow these in packages (Would like to get rid of them or rely on mypy
# in the future)
# - F403: from/import * used; unable to detect undefined names
# - F405: undefined name or from *
# - F821: undefined name (needed with from/import *)
