## 🔗 Smart File Combining (NEW in v1.1.0!)

### **Solve Multi-File Import Issues**
ObfusLite now includes powerful file combining functionality that solves the common problem where obfuscated multi-file applications can't find their modules.

#### **The Problem:**
```python
# main.py
from utils import helper_function  # ❌ Fails after obfuscation
from config import settings       # ❌ Import errors

# After obfuscating each file separately, imports break!
```

#### **The Solution:**
```bash
# Combine all files into one before obfuscating
obfuslite combine main.py --obfuscate

# Creates a single, self-contained file that works perfectly!
```

#### **CLI Usage:**
```bash
# Basic combine
obfuslite combine main.py

# Combine with custom output
obfuslite combine main.py -o my_app.py

# Combine and auto-obfuscate
obfuslite combine main.py --obfuscate -t fast_xor -l 2

# Advanced obfuscation
obfuslite combine main.py --obfuscate -t quantum -l 3
```

#### **GUI Usage:**
1. Launch GUI: `obfuslite gui`

3. **Compile with PyInstaller**:
   ```bash
   pyinstaller --onefile obfuscated_app.py
   ```

### Batch Processing Workflow
1. **Use GUI Batch Processing** to obfuscate multiple files
2. **Export as ZIP** for organized distribution
3. **Compile main entry point**:
   ```bash
   pyinstaller --onefile main_obfuscated.py
   ```

The resulting .exe will contain your obfuscated code that reconstructs itself at runtime.

        if file.endswith('.py'):
            file_path = os.path.join(root, file)

            with open(file_path, 'r') as f:
                code = f.read()

            result = obfuscator.obfuscate(code, technique='fast_xor')
            standalone = obfuscator.create_standalone_file(result)

            output_path = file_path.replace('.py', '_protected.py')

4. Add to GUI dropdown menu

Example:
```python
from obfuslite.encoders.base import BaseEncoder

class MyCustomEncoder(BaseEncoder):
    def encode(self, data: str) -> Dict[str, Any]:
        # Your encoding logic here
        pass

    def decode(self, encoded_data: Any, metadata: Dict[str, Any]) -> str:
        # Your decoding logic here
        pass

# Register the technique
from obfuslite import Obfuscator
obfuscator = Obfuscator()
obfuscator.register_technique('custom', MyCustomEncoder())
```
