Migration Guide: From Scripts to Library

This guide helps you migrate from using standalone scripts to the new sovereign level monolithic dense library.

Overview

The new library consolidates all functionality into a unified, object-oriented interface while maintaining backward compatibility with existing scripts.

Key Changes

Before (Scripts)

# Old approach - separate scripts
python scripts/fetch-public-files.py
python scripts/process-pdfs.py
python scripts/generate-search-index.py

After (Library)

# New approach - unified library
from epstein_files import Hub

hub = Hub()
hub.fetch_public_files()
hub.process_documents()
hub.generate_search_index()

Migration Steps

1. Install the Library

# Install in development mode
pip install -e .

# Or install normally
pip install .

2. Update Your Code

Fetching Public Files

Before:

# scripts/fetch-public-files.py
import requests
# ... manual implementation

After:

from epstein_files import Hub

hub = Hub()
results = hub.fetch_public_files(sources=["fbi_vault", "doj"])
print(f"Fetched {results['total_files']} files")

Processing Documents

Before:

# scripts/process-pdfs.py
import pypdf
# ... manual implementation

After:

from epstein_files import Hub

hub = Hub()
results = hub.process_documents(enable_ocr=True)
print(f"Processed {results['total_processed']} documents")

Generating Search Index

Before:

# scripts/generate-search-index.py
import json
# ... manual implementation

After:

from epstein_files import Hub

hub = Hub()
results = hub.generate_search_index()
print(f"Indexed {results['total_documents']} documents")

3. Configuration Management

Before (Environment Variables)

export DATA_DIR=data
export ENABLE_OCR=true

After (Unified Config)

from epstein_files import Hub

hub = Hub()

# Access configuration
data_dir = hub.config.get("data_dir")

# Modify configuration
hub.config.set("enable_ocr", True)
hub.config.set("max_workers", 8)

# Get all paths
paths = hub.config.get_paths()

4. Data Management

Before (Manual File Handling)

import json
with open("data/file.json", "r") as f:
    data = json.load(f)

After (DataManager)

from epstein_files import Hub

hub = Hub()

# Load data
data = hub.data.load_json("data/file.json")

# Save data
hub.data.save_json(data, "data/output.json")

# List files
files = hub.data.list_files("data/public_files", "*.pdf")

# Get statistics
stats = hub.data.get_statistics()

5. Caching

Before (No Built-in Caching)

# Manual cache implementation required

After (CacheManager)

from epstein_files import Hub

hub = Hub()

# Cache data
hub.cache.set("key", value, namespace="processing")

# Retrieve cached data
value = hub.cache.get("key", namespace="processing")

# Cache decorator
@hub.cache.cached(namespace="wikipedia", ttl=168)
def expensive_operation():
    return result

# Get cache statistics
stats = hub.cache.get_stats()

6. Running Full Pipeline

Before (Multiple Scripts)

#!/bin/bash
python scripts/fetch-public-files.py
python scripts/fetch-wikipedia-data.py
python scripts/process-pdfs.py
python scripts/generate-search-index.py

After (Single Command)

from epstein_files import Hub

hub = Hub()

# Run entire pipeline
results = hub.run_full_pipeline(force_refresh=False)

# Or use CLI
# epstein-hub pipeline

CLI Usage

The library provides a command-line interface:

# Get system status
epstein-hub status

# Fetch public files
epstein-hub fetch

# Process documents
epstein-hub process

# Generate search index
epstein-hub index

# Run full pipeline
epstein-hub pipeline

# Cleanup
epstein-hub cleanup

# Use debug mode
epstein-hub status --debug

# Force refresh
epstein-hub fetch --force

Backward Compatibility

Scripts Still Work

All original scripts continue to work:

python scripts/fetch-public-files.py
python scripts/process-pdfs.py
python scripts/generate-search-index.py

Gradual Migration

You can migrate gradually:

Keep using scripts for some operations
Use library for new functionality
Migrate scripts one at a time
Eventually deprecate old scripts

Advanced Usage

Direct Subsystem Access

from epstein_files import Hub

hub = Hub()

# Access subsystems directly
hub.public_files.fetch_fbi_vault()
hub.wikipedia.fetch_character_data("Name")
hub.pdf_processor.process_file("doc.pdf")
hub.search_indexer.build_index()
hub.agents.run_agent("pdf_analysis", task)

Context Manager

from epstein_files import Hub

# Automatic cleanup
with Hub() as hub:
    hub.fetch_public_files()
    hub.process_documents()
    hub.generate_search_index()
# Cleanup happens automatically

Custom Configuration

from epstein_files import Hub
from pathlib import Path

# Custom config path
hub = Hub(config_path=Path(".env.custom"))

# Or modify after initialization
hub.config.set("data_dir", "custom_data")
hub.config.set("max_workers", 16)
hub.config.ensure_directories()

Benefits of Migration

1. Unified Interface

Single import for all functionality
Consistent API across all operations
Reduced code duplication

2. Better Performance

Intelligent caching reduces redundant operations
Lazy loading of subsystems
Parallel processing support

3. Improved Maintainability

Centralized configuration
Better error handling
Comprehensive logging

4. Enhanced Features

Context manager support
CLI interface
Statistics and monitoring
Automatic cleanup

5. Type Safety

Type hints throughout
Better IDE support
Fewer runtime errors

Common Migration Patterns

Pattern 1: Simple Script to Library

Before:

# my_script.py
import scripts.fetch_public_files as fetch
fetch.main()

After:

# my_script.py
from epstein_files import Hub

hub = Hub()
hub.fetch_public_files()

Pattern 2: Configuration

Before:

import os
data_dir = os.getenv("DATA_DIR", "data")

After:

from epstein_files import Hub

hub = Hub()
data_dir = hub.config.get("data_dir")

Pattern 3: Data Operations

Before:

import json
from pathlib import Path

data_path = Path("data/file.json")
with open(data_path, "r") as f:
    data = json.load(f)

After:

from epstein_files import Hub

hub = Hub()
data = hub.data.load_json("data/file.json")

Testing After Migration

# test_migration.py
from epstein_files import Hub

def test_basic_operations():
    hub = Hub()
    
    # Test status
    status = hub.get_status()
    assert status['config']['valid']
    
    # Test operations
    results = hub.fetch_public_files()
    assert 'total_files' in results
    
    results = hub.process_documents()
    assert 'total_processed' in results
    
    results = hub.generate_search_index()
    assert 'total_documents' in results

Troubleshooting

Issue: Module not found

# Solution: Install the library
pip install -e .

Issue: Configuration not loading

# Solution: Ensure .env file exists or create config
from epstein_files import Hub

hub = Hub()
hub.config.ensure_directories()

Issue: Import errors

# Solution: Check PYTHONPATH
import sys
sys.path.insert(0, '/path/to/Hub_of_Epstein_Files_Directory')

from epstein_files import Hub

Phase 2 (Next): Deprecation warnings added to scripts
Phase 3 (Future): Scripts marked deprecated
Phase 4 (Later): Scripts removed (with sufficient notice)

The new library provides:

✅ Unified interface for all operations
✅ Backward compatibility with existing scripts
✅ Better performance through caching
✅ Enhanced features (CLI, context manager, etc.)
