⚡ Quick Start

Automate in 5 Minutes

1. Basic Script Example

Create search_script.sh:

#!/bin/bash
# Search for a term and save results
python naviduck.py << 'EOF'
s "$1"
# Results automatically displayed
quit
EOF

Run it:

chmod +x search_script.sh
./search_script.sh "python tutorial"

2. Python One-Liner

# Quick search from Python
import subprocess
result = subprocess.run(
    ['python', 'naviduck.py'],
    input=b's python tutorial\nquit\n',
    capture_output=True,
    text=True
)
print(result.stdout)

3. Scheduled Daily Search

# Add to crontab
crontab -e
# Add: 0 9 * * * /path/to/search_script.sh "daily news"

---

💻 Command-Line Automation

Basic Input Redirection

Simple Search Script

#!/bin/bash
# search_term.sh - Search and capture results
TERM="$1"
python naviduck.py << EOF
s $TERM
quit
EOF

Multiple Commands

#!/bin/bash
# research_script.sh - Complete research workflow
TOPIC="$1"

python naviduck.py << EOF
clear
s $TOPIC
1          # Open first result
b          # Bookmark it
h          # History
q          # Back to main
ai explain $TOPIC
quit
EOF

Capture Output to File

#!/bin/bash
# search_to_file.sh
QUERY="$1"
OUTPUT_FILE="${2:-results.txt}"

python naviduck.py << EOF | tee "$OUTPUT_FILE"
s $QUERY
quit
EOF

echo "Results saved to $OUTPUT_FILE"

Advanced Shell Scripting

Interactive Script

#!/bin/bash
# interactive_search.sh
echo "What would you like to search for?"
read -r query

python naviduck.py << EOF
s $query

# Pause for user to view results
echo "Press Enter to continue..."
read -r

quit
EOF

Batch Processing

#!/bin/bash
# batch_search.sh
SEARCHES=("python tutorial" "machine learning" "web development")

for search in "${SEARCHES[@]}"; do
    echo "=== Searching: $search ==="
    python naviduck.py << EOF
s $search
sleep 2  # Wait for results display
quit
EOF
    echo ""  # Blank line
done

Error Handling

#!/bin/bash
# robust_search.sh
set -e  # Exit on error

search_term="$1"

if [ -z "$search_term" ]; then
    echo "Error: No search term provided"
    exit 1
fi

if ! command -v python &> /dev/null; then
    echo "Error: Python not found"
    exit 1
fi

# Timeout after 30 seconds
timeout 30 python naviduck.py << EOF
s $search_term
quit
EOF

if [ $? -eq 124 ]; then
    echo "Error: Search timed out"
    exit 1
fi

Using Expect for Complex Automation

Expect Script Example

#!/usr/bin/expect -f
# naviduck_automation.exp
set timeout 30
set query [lindex $argv 0]

spawn python naviduck.py

expect "naviduck>"
send "s $query\r"

expect {
    "Select an option:" {
        send "1\r"  # Open first result
        exp_continue
    }
    "Page Actions:" {
        send "b\r"  # Bookmark
        exp_continue
    }
    "naviduck>" {
        send "quit\r"
    }
    timeout {
        send_user "Timeout occurred\n"
        exit 1
    }
}

expect eof

Install and Use Expect

# Install expect
sudo apt install expect  # Ubuntu/Debian
sudo yum install expect  # RHEL/CentOS
brew install expect      # macOS

# Run expect script
expect naviduck_automation.exp "python tutorial"

🐍 Python API & Integration

Direct Module Import

Import NaviDuck Components

# naviduck_integration.py
import sys
import os

# Add NaviDuck to path
sys.path.insert(0, '/path/to/naviduck')

# Import core components
from naviduck import BrowserState, NetworkManager, SearchManager, PageLoader

# Initialize components
state = BrowserState()
network = NetworkManager(state)
search_mgr = SearchManager(state, network)
page_loader = PageLoader(state, network)

# Use components directly
results = search_mgr.search("python tutorial")
for result in results[:3]:
    print(f"Title: {result['title']}")
    print(f"URL: {result['url']}")
    print()

Custom Search Function

def search_and_analyze(query, max_results=5):
    """Search and return analyzed results"""
    results = search_mgr.search(query)
    
    analysis = {
        'query': query,
        'total_results': len(results),
        'engines_used': list(set(r['engine'] for r in results)),
        'domains': list(set(urlparse(r['url']).netloc for r in results)),
        'top_results': results[:max_results]
    }
    
    return analysis

# Usage
analysis = search_and_analyze("artificial intelligence")
print(f"Found {analysis['total_results']} results")
for result in analysis['top_results']:
    print(f"- {result['title']}")

Subprocess Integration

Performance Optimization

Reduce Startup Time

# Cache NaviDuck initialization
import pickle
import hashlib

def cached_search(query, cache_dir="cache"):
    """Cache search results"""
    os.makedirs(cache_dir, exist_ok=True)
    
    # Create cache key
    cache_key = hashlib.md5(query.encode()).hexdigest()
    cache_file = os.path.join(cache_dir, f"{cache_key}.pkl")
    
    # Check cache
    if os.path.exists(cache_file):
        with open(cache_file, 'rb') as f:
            return pickle.load(f)
    
    # Perform search
    result = perform_search(query)
    
    # Save to cache
    with open(cache_file, 'wb') as f:
        pickle.dump(result, f)
    
    return result

Parallel Processing

from concurrent.futures import ThreadPoolExecutor, as_completed

def parallel_searches(queries, max_workers=4):
    """Perform multiple searches in parallel"""
    results = {}
    
    with ThreadPoolExecutor(max_workers=max_workers) as executor:
        # Submit all searches
        future_to_query = {
            executor.submit(perform_search, query): query
            for query in queries
        }
        
        # Collect results as they complete
        for future in as_completed(future_to_query):
            query = future_to_query[future]
            try:
                results[query] = future.result()
            except Exception as e:
                results[query] = f"Error: {e}"
    
    return results

Security Considerations

Sanitize Inputs

import re

def sanitize_input(user_input):
    """Sanitize user input for NaviDuck commands"""
    # Remove dangerous characters
    sanitized = re.sub(r'[;&|`$]', '', user_input)
    
    # Limit length
    if len(sanitized) > 1000:
        sanitized = sanitized[:1000]
    
    return sanitized

# Usage
safe_query = sanitize_input(user_query)

Rate Limiting

from collections import deque
import time

class RateLimiter:
    def __init__(self, max_calls, period):
        self.max_calls = max_calls
        self.period = period
        self.calls = deque()
    
    def can_call(self):
        """Check if call is allowed"""
        now = time.time()
        
        # Remove old calls
        while self.calls and now - self.calls[0] > self.period:
            self.calls.popleft()
        
        if len(self.calls) < self.max_calls:
            self.calls.append(now)
            return True
        
        return False

# Usage
limiter = RateLimiter(max_calls=10, period=60)  # 10 calls per minute

if limiter.can_call():
    perform_search(query)
else:
    print("Rate limit exceeded. Please wait.")

💡 Automation Wisdom

Golden Rules for Automation

1. Start simple - Automate one task at a time
2. Test thoroughly - Edge cases matter
3. Add monitoring - Know when things fail
4. Document clearly - Future you will thank you
5. Share and learn - Community improves everything

Remember:

"Automation is not about replacing humans, but about amplifying human capability. Automate the routine, so you can focus on the remarkable."

❓ Automation FAQ

Q: Can I run NaviDuck without the terminal interface? A: Yes, through subprocess or future API. Currently subprocess is the way.

Q: Is it safe to automate sensitive searches? A: Be cautious. Use appropriate privacy measures (Tor, VPN) for sensitive tasks.

Q: How many concurrent searches can I run? A: Limited by your system and network. Start with 2-3, monitor performance.

Q: Can I automate NavAI questions? A: Yes, same as searches: ai your question

Q: Will automation get me blocked from search engines? A: Use delays between requests and respect rate limits to avoid blocks.

Q: Can I schedule automations on a cloud server? A: Yes, if the server has Python and internet access.

Q: How do I handle CAPTCHAs in automation? A: NaviDuck auto-switches engines on CAPTCHA. For automation, use Tor-friendly engines.

Q: Can I contribute automation scripts to NaviDuck? A: Absolutely! Share on GitHub or community forums.
