Without `if __name__ == "__main__": sys.exit(main())` at the bottom of cli.py, `python -m cmos.cli format <path>` imports the module but never invokes main(), so the process silently exits 0 with empty stdout — indistinguishable from a successful run that produced no output. Discovered during real-draft testing on 2026-04-11. Adds a regression test that subprocesses the CLI with --help and asserts on stdout content. argparse --help exits 0 in both broken and fixed states; stdout content is the only discriminator. Both invocation paths now work: - uv run cmos format <path> (pyproject script entry) - uv run python -m cmos.cli format <path> (module invocation)
cmos — Chicago Manual of Style 18 bibliography reformatter
A Python tool that reformats the bibliography section of an English-language markdown draft to CMOS 18th edition, notes-and-bibliography form.
Accuracy-first, iterative, built with a karpathy/autoresearch-style dev loop.
See program.md for the goal specification and
/home/claudecode1/.claude/plans/pure-mixing-yao.md for the implementation plan.
