🔍 Code Extractor

Main entry point for a Streamlit-based FileCloud Data Processor application that handles authentication, session state management, and navigation between multiple modules including document audit, controlled documents, settings, and reports.

Purpose

This function serves as the central orchestrator for a multi-module Streamlit application. It configures the page layout, manages user authentication state, and routes users to different functional modules based on their selections. The application appears to be a document management system with audit capabilities, controlled document workflows, settings configuration, and reporting features.

Source Code

def main():
    """Main application entry point."""
    # Set up page config
    st.set_page_config(
        page_title="FileCloud Data Processor",
        page_icon="📊",
        layout="wide",
        initial_sidebar_state="expanded"
    )
    
    # Initialize session state if needed
    if 'authenticated' not in st.session_state:
        st.session_state['authenticated'] = False
    
    if 'current_module' not in st.session_state:
        st.session_state['current_module'] = None
    
    # Authentication check
    if not st.session_state['authenticated']:
        login_page()
        return
    
    # Navigate to the selected module
    current_module = st.session_state.get('current_module')
    
    if current_module == 'document_audit':
        document_audit_page()
    elif current_module == 'controlled_docs':
        controlled_docs_navigation()
    elif current_module == 'settings':
        settings_page()
    elif current_module == 'reports':
        reports_page()
    else:
        main_page()

Return Value

No return value (implicitly returns None). The function controls application flow through Streamlit's rendering system and session state management.

Required Imports

import streamlit as st

Conditional/Optional Imports

These imports are only needed under specific conditions:

from login_module import login_page

from document_audit_module import document_audit_page

from controlled_docs_module import controlled_docs_navigation

from settings_module import settings_page

from reports_module import reports_page

from main_module import main_page

Usage Example

import streamlit as st
from login_module import login_page
from document_audit_module import document_audit_page
from controlled_docs_module import controlled_docs_navigation
from settings_module import settings_page
from reports_module import reports_page
from main_module import main_page

def main():
    st.set_page_config(
        page_title="FileCloud Data Processor",
        page_icon="📊",
        layout="wide",
        initial_sidebar_state="expanded"
    )
    
    if 'authenticated' not in st.session_state:
        st.session_state['authenticated'] = False
    
    if 'current_module' not in st.session_state:
        st.session_state['current_module'] = None
    
    if not st.session_state['authenticated']:
        login_page()
        return
    
    current_module = st.session_state.get('current_module')
    
    if current_module == 'document_audit':
        document_audit_page()
    elif current_module == 'controlled_docs':
        controlled_docs_navigation()
    elif current_module == 'settings':
        settings_page()
    elif current_module == 'reports':
        reports_page()
    else:
        main_page()

if __name__ == '__main__':
    main()

Best Practices

• This function must be called only once as the application entry point, typically in an if __name__ == '__main__': block
• Ensure all page functions (login_page, document_audit_page, etc.) are properly defined before calling main()
• The st.set_page_config() must be the first Streamlit command called and can only be called once per app
• Session state variables 'authenticated' and 'current_module' should be managed consistently across all page modules
• The function uses early return pattern after login_page() to prevent unauthorized access to other modules
• Module navigation relies on string matching, so ensure 'current_module' values match exactly the expected strings
• Consider implementing error handling for missing page functions to prevent application crashes
• The wide layout and expanded sidebar are configured for a dashboard-style application with multiple navigation options
