Code Review
This pull request refactors the group_photos function to reduce its complexity by extracting logic into helper functions, which is a great improvement for readability and maintainability. My review includes a suggestion to further refine one of the new helper functions, move_file_to_group, to better align with the Single Responsibility Principle and improve its error handling.

| """Moves the file to the current group folder if it's not already there.""" | ||

The function move_file_to_group currently mixes two responsibilities: moving a file and calculating the new group size. To improve modularity and adhere to the Single Responsibility Principle, this function could be refactored to only handle the file move and return a boolean indicating success. This also provides an opportunity to use more specific exception handling (shutil.Error, OSError) instead of a broad Exception.
After applying this suggestion, you would need to update the call site in process_file (lines 84-86) to something like:
if move_file_to_group(file_path, current_group_folder):
current_group_size += file_size| def move_file_to_group(file_path, current_group_folder, file_size, current_group_size): | |
| """Moves the file to the current group folder if it's not already there.""" | |
| abs_file_path = os.path.abspath(file_path) | |
| abs_group_folder = os.path.abspath(current_group_folder) | |
| if os.path.commonpath([abs_file_path, abs_group_folder]) != abs_group_folder: | |
| try: | |
| shutil.move(file_path, current_group_folder) | |
| print(f"Moved photo '{file_path}' to '{current_group_folder}'") | |
| return current_group_size + file_size | |
| except Exception as e: | |
| print(f"Failed to move photo '{file_path}': {e}") | |
| return current_group_size | |
| def move_file_to_group(file_path, current_group_folder): | |
| """Moves the file to the current group folder if it's not already there.""" | |
| abs_file_path = os.path.abspath(file_path) | |
| abs_group_folder = os.path.abspath(current_group_folder) | |
| if os.path.commonpath([abs_file_path, abs_group_folder]) != abs_group_folder: | |
| try: | |
| shutil.move(file_path, current_group_folder) | |
| print(f"Moved photo '{file_path}' to '{current_group_folder}'") | |
| return True | |
| except (shutil.Error, OSError) as e: | |
| print(f"Failed to move photo '{file_path}': {e}") | |
| return False |

- The style guide states that functions should follow the Single Responsibility Principle. The suggested change separates the file moving logic from the size calculation logic to better adhere to this principle. (link)

Pull request overview
Refactors group_photos in the Google Photos “Splitter” utility to reduce nesting by extracting file-handling logic into helper functions, improving readability and maintainability.
Changes:
- Extracted per-file handling into
process_file,ensure_space_in_group, andmove_file_to_group. - Simplified the inner loop of
group_photosby delegating sizing, group rollover, and move logic. - Added
pr_desc.mdcontaining the PR description text.

| 🎯 **What:** The `group_photos` function in `Cachyos/Scripts/WIP/gphotos/Splitter.py` had high cognitive complexity due to a deeply nested inner loop. | ||
| 💡 **Why:** Deep nesting makes the code harder to read, maintain, and reason about. By extracting the core file processing logic into smaller, dedicated helper functions (`process_file`, `ensure_space_in_group`, and `move_file_to_group`), the structure becomes clearer, and the iteration state can be managed explicitly through returns. | ||
| ✅ **Verification:** Validated that `ruff check` passes and the existing test suite (`python3 Cachyos/Scripts/WIP/gphotos/test_splitter.py`) passes perfectly, confirming that group counting, sizing, and moving boundaries all function properly without regression. | ||
| ✨ **Result:** A simplified `group_photos` function with significantly reduced nesting and cognitive complexity, promoting cleaner code health. |
