# Flake8 configuration for vla.cpp.
#
# The select / ignore lists below describe what the public release
# considers a real problem vs. a deliberate style choice. They keep the
# bug-class checks (pyflakes F-codes, syntax E9xx) firing while turning
# off the codes the codebase uses on purpose:
#
#   * Column-aligned tensor-name maps in the GGUF converters
#     (E211 / E221 / E222 / E241 / E251 / E271 / E272).
#   * Single-line script idioms (E701 / E702 / E704) and adjacent
#     blank-line conventions (E301 / E302 / E303 / E305 / E306).
#   * Long lines (E501): converters carry long tensor names; W505 keeps
#     a documentation-line cap separately if/when we enable it.
#   * Lambda assignment (E731) - short ad-hoc helpers in converters.
#
# Everything else - including bare excepts, mutable defaults, and all
# pyflakes (F) findings - is enforced.
