# flake8 settings for Spack core files.

# These exceptions are for Spack core files. We're slightly more lenient
# with packages.  See .flake8_packages for that.
#
# E1: Indentation
# - E129: visually indented line with same indent as next logical line
#
# E2: Whitespace
# - E221: multiple spaces before operator
# - E241: multiple spaces after ','
# - E272: multiple spaces before keyword
#
# E7: Statement
# - E731: do not assign a lambda expression, use a def
#
# W5: Line break warning
# - W503: line break before binary operator
# - W504: line break after binary operator
#
# These are required to get the package.py files to test clean:
# - F999: syntax error in doctest
#
# N8: PEP8-naming
# - N801: class names should use CapWords convention
# - N813: camelcase imported as lowercase
# - N814: camelcase imported as constant
#
# F4: pyflakes import checks, these are now checked by mypy more precisely
# - F403: from module import *
# - F405: undefined name or from *
#
# Black ignores, these are incompatible with black style and do not follow PEP-8
# - E203: white space around slice operators can be required, ignore : warn
# - W503: see above, already ignored for line-breaks
