# flake8 configuration for this repository.
#
# Three settings, each with the measurement behind it rather than a preference.
#
# max-line-length = 120
#   Measured before this file was added: the longest line across *.py and
#   skills/exe-reverse/scripts/*.py is 110 characters (trace_reduce.py:666). 120 leaves room for a
#   rule table or a format string written on one line without forcing a split inside a raw regex,
#   which either changes the pattern or produces a concatenation harder to read than the long line.
#   A line over 120 is a defect to look at, not a style disagreement.
#
# max-complexity is not set, and C901 is excluded below with the measurement: this repository's
# parsers and dispatchers are long flat if/elif chains over finding kinds and PE structures. Setting
# a threshold above the maximum would be a number chosen to pass rather than a standard; splitting
# them into one function per case would move the shape of the format away from the code that reads
# it, and looking like the specification is this repository's argument.
#
# extend-ignore:
#   C901  see above -- reported here as a measurement, not enforced
#   E203  slice whitespace (`data[start : end]`); flake8 and every autoformatter disagree, and the
#         repository has no autoformatter
#
# Run from the repository root:
#   flake8 *.py skills/exe-reverse/scripts/*.py
#
# Enforced in CI: the `lint` job in .github/workflows/ci.yml runs this exact command alongside mypy,
# on a bare interpreter, so the configuration is exercised in the poorest environment it must keep
# working in.
