Conversation
When an unhandled exception occurs, the app now saves each open package to a recovery file in the settings directory. On the next launch, if a recovery file is found for a previously opened file, the user is asked whether to restore the auto-saved version or discard it and open the original. Recovery files are cleaned up after a successful manual save. - aas_editor/settings/app_settings.py: add RECOVERY_DIR constant - aas_editor/utils/recovery.py: new helper to scan for recovery index files - aas_editor/package.py: add write_recovery(), delete_recovery(), recovery_path() - aas_editor/utils/exceptionhook.py: activate hook, add set_crash_callback() - main.py: uncomment exceptionhook import so hook is registered at startup - aas_editor/editorApp.py: register crash callback, prompt user to restore on open - aas_editor/treeviews/treeview_pack.py: delete recovery files after successful save https://claude.ai/code/session_01UFxYCRhX5pM18utUMv55rP

This pull request implements a robust crash recovery system for the editor, ensuring that unsaved changes are not lost in the event of an unexpected crash. The main changes introduce automatic recovery file management, prompt users to restore unsaved work, and ensure cleanup of recovery data after successful saves. Additionally, it improves exception handling to trigger recovery logic on crashes.
Crash Recovery System:
Added a mechanism to auto-save recovery files for open packages when the application crashes, and prompt the user to restore unsaved changes on the next startup. This includes functions to find, write, and delete recovery files, as well as logic to remap recovered files to their original paths. (
