Note&Cross

Stanford University (Code in Place) - Final Project Author: David Jimenez

Note&Cross is a command-line interface (CLI) task manager written in Python. The application provides local data persistence to manage, track, and log daily operations and pending objectives through a flat-file storage system.

Technical Features

• Data Persistence: Uses the Python os module to handle file system verification and stream updates directly to a local text archive using UTF-8 encoding.
• Input Validation: Implements runtime exception handling via try-except blocks to catch ValueError anomalies during user type conversion.
• Modular Architecture: Separates system logic into distinct operational layers for data loading, state synchronization, and main process execution loop.
• Dynamic Indexing: Utilizes tracking loops to dynamically re-index active elements whenever items are removed or updated.

Technical Specifications

• Language: Python 3.x
• Standard Libraries: os
• Storage Architecture: Flat-file system (my_tasks.txt)

Core Operations

1. Task Registration: Appends strings to the memory array with optional conditional formatting for deadlines.
2. Index-Based Removal: Disposes of targeted array elements based on user-selected numeric indexes.
3. Batch Reset: Flushes the memory array and mirrors the state to the storage archive after user confirmation.
4. Auto-Commit on Exit: Synchronizes the current array state to disk prior to process termination.

Deployment and Execution

Prerequisites: Python 3 installed on the host system.

1. Clone the repository: git clone https://github.com/djc1416/note-cross

2. Navigate to the project directory: cd note-cross

3. Execute the script: python main.py

The application automatically initializes the reference storage file during the first execution cycle if no prior database file is found.
