ruff.toml

# Which ruff rules 4CAT checks, and why the list is short.
#
# .github/workflows/ruff.yml pins the ruff version too, so that the same code
# gives the same answer for everyone.
#
# New rules worth reviewing under ruff 0.16.1:
#
#   ASYNC    blocking calls such as time.sleep or open inside an async function
#   W605     a backslash in a string that Python does not read as an escape

# The oldest Python that 4CAT supports
