Repository: deshaw/pyflyby
Base commit: c25497f (image tag)
Issue: tidy-imports --black fails with no pyproject.toml (PyInf#11819) When using --black outside of a tree with a pyproject.toml, tidy-imports 1.8.9 crashes with the attached traceback. tidy-imports 1.8.6 doesn't exhibit this issue. Started happening after commit - https://github.com/deshaw/pyflyby/commit/8c10f4971d328fc985b0910f1397b4c36a67c318 ``` > tidy-imports --black /var/tmp/a.py --no-remove-unused Traceback (most recent call last): File "/usr/local/python/python-3.11/std/lib64/python3.11/site-packages/pyflyby/_cmdline.py", line 391, in process_actions action(m)

Files to edit

lib/python/pyflyby/_importstmt.py

Approach: Add a null check in `read_black_config`: if `path_config` is `None`, return `{}` immediately instead of proceeding to parse.
