# ITU-T Report Generator - User Guide

## 🚀 Quick Start

### 1. Install Dependencies

```bash
# Activate your virtual environment (from project root)
cd ../../..  # Go to sg17collab/
venv\Scripts\activate  # Windows

# Install dependencies
cd auto-doc-latex/web-app
pip install Flask Werkzeug beautifulsoup4 lxml python-dateutil
```

**Note:** `pycurl` may fail on Windows. It's only needed for the backend scripts (scraping ITU website), not for the web interface itself.

### 2. Run the Application

```bash
cd auto-doc-latex/web-app
python app.py
```

You should see:
```
* Running on http://127.0.0.1:5000
* Debug mode: on
```

### 3. Open in Browser

Navigate to: **http://localhost:5000**

## ✏️ Manual Sections

Some sections require manual input. Look for:

- `\textit{For manual entry.}` - Fill these sections manually
- `\textit{TODO: ...}` - Placeholders for observations
- `\tdNumber` - TD number (assigned by ITU secretariat)

Typical manual sections:
- Executive summary details
- Observations on liaison statements
- Deleted work items justification

## ⚙️ Configuration

### Timeout Settings

Edit `config.py` to adjust:

```python
GENERATION_TIMEOUT = 300        # 5 minutes (in seconds)
TEMP_FILE_MAX_AGE = 1 hour     # Auto-cleanup age
MAX_CONTENT_LENGTH = 16 MB     # Max file upload size
```

### Debug Mode

To disable debug mode (production):

```python
# In app.py
app.run(
    host='127.0.0.1',
    port=5000,
    debug=False  # Change to False
)
```

## 🐛 Troubleshooting

### "Download not found or expired"
- Files are auto-deleted after 1 hour
- Generate the report again

### "Network error"
- Check internet connection
- ITU website must be accessible
- Try again in a few minutes

### "Validation error"
- Check that start date < end date
- All required fields must be filled
- Dates must be in YYYY/MM/DD format

### Flask won't start
- Check that port 5000 is not in use
- Kill existing Python processes: `taskkill /F /IM python.exe`
- Reinstall dependencies: `pip install -r requirements.txt`

---

## 🔒 Security Notes

- The app runs on `localhost` only (127.0.0.1)
- Not exposed to the internet
- Session-only (no data persistence)
- Files auto-delete after 1 hour

## 💡 Tips

- **Dates:** Use YYYY/MM/DD format (e.g., 2025/12/03)
- **Meeting Days:** Comma-separated (e.g., 2025/12/10, 2025/12/11)
- **Patience:** Report generation takes 2-5 minutes
- **Overleaf:** Best for PDF compilation (no local LaTeX needed)
- **Manual Review:** Always review generated content before submission
