Summary

Adds opt-in CLI flags to organize generated files by the date they are written:

  • --date-based-output stores outputs under a date subfolder; default behavior remains unchanged.
  • --date-output-format accepts a standard strftime format, defaulting to %Y-%m-%d.
  • Existing filename-prefix subfolders are preserved beneath the date folder.

Operator quality of life

Long-running or high-volume installations accumulate large flat output directories that are slow to browse, harder to back up, and tedious to clean up. This gives operators a built-in, script-friendly organization policy without custom nodes, wrapper scripts, or manual file moves. The path is resolved for every save, so a process running across midnight automatically rolls into the next date folder without a restart. Per-folder counters also stay compact and meaningful.

Compatibility

The behavior is entirely opt-in. Existing workflows, API integrations, output paths, and filename-prefix behavior are unchanged unless the flag is supplied.

Tests

📝 Walkthrough

Walkthrough

The CLI adds --date-based-output and --date-output-format. When enabled, get_save_image_path prepends a subfolder based on the current local date and configured strftime format. Tests cover both default output paths and date-based paths using a fixed timestamp.

Merge Risk: 🟡 Moderate · up to f1933

The opt-in date-based output feature preserves existing default behavior, but saves around local midnight may place files in date folders that disagree with their filename timestamps, creating a bounded organization and automation risk that needs owner acceptance or correction.

Use one local-time snapshot for filename and subfolder dates. When date variables and date-based output are enabled, compute_vars() and date_subfolder call time.localtime() separately. If execution crosses local midnight, the filename and subfolder can contain different dates. Pass one time.struct_time to both operations and add a boundary regression test.

Reject empty and dot rendered date folders.

When --date-output-format renders to "" or ".", os.path.join(output_dir, subfolder) resolves to output_dir, so date-based output silently loses its date partition. Reject these values before joining them. The existing containment check does not catch this case.
