🧹 Refactor main function complexity in cia_3ds_decryptor.py#226
🧹 Refactor main function complexity in cia_3ds_decryptor.py#226
Conversation
Extracted logic from the main function into several smaller, modular helper functions: - initialize_tools - sanitize_filenames - get_file_counts - ask_for_conversion - run_decryption - run_conversion - display_summary This improves readability and maintainability while preserving the original functionality and sequence of operations. Verified with existing tests and ruff. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>

Code Review
This pull request effectively refactors the main function in cia_3ds_decryptor.py, significantly improving its readability and maintainability by breaking down a large monolithic function into smaller, focused helper functions. The new structure makes the script's execution flow much clearer. I have one suggestion to further improve the error logging in one of the new helper functions.

The error handling in run_decryption could be improved for better diagnostics. When a task fails with an exception, the current implementation logs the exception but doesn't specify which file failed. This is because the futures dictionary only stores the task type ('3ds' or 'cia').
To provide more context, you can store both the task type and the filename in the futures dictionary, similar to how run_conversion stores the filename. This will allow you to log the specific file that caused the error, making debugging much easier.

Pull request overview
This PR refactors the monolithic main() function in cia_3ds_decryptor.py into 7 focused helper functions: initialize_tools, sanitize_filenames, get_file_counts, ask_for_conversion, run_decryption, run_conversion, and display_summary. The resulting main() is a clear, linear orchestrator.
Changes:
- Extracted 7 helper functions from the original
main(), each with a single responsibility and proper type annotations/docstrings. - Moved the "no files found" early-return logic into the new
main()orchestrator (previously inline). - Minor formatting cleanup: collapsed multi-line
logging.infocalls into single lines and removed inline comments.

This PR addresses the high complexity of the
mainfunction inCachyos/Scripts/WIP/emu/cia_3ds_decryptor.py.🎯 What: The
mainfunction was a long, monolithic block of code handling multiple responsibilities. I refactored it into 7 focused helper functions.💡 Why: Smaller functions are easier to understand, test, and maintain. It also makes the high-level logic of the script clear at a glance in the
mainorchestrator.✅ Verification:
python3 -m py_compile.python3 Cachyos/Scripts/WIP/emu/test_decryptor_counters.py.ruff check.✨ Result: Improved code health and reduced cognitive load for future maintainers.
