# 🚀 Smart Auto-Complete - Setup Guide

This guide will help you set up and run the Smart Auto-Complete application.

## 📋 Prerequisites

- **Python 3.8+** (recommended: Python 3.9 or higher)
- **pip** (Python package installer)
- **API Keys** from one or both providers:
  - [OpenAI API Key](https://platform.openai.com/api-keys)
  - [Anthropic API Key](https://console.anthropic.com/)

## 🚀 Quick Installation

### Option 1: Automated Installation (Recommended)

```bash
# Run the installation script
python install.py
```

This will:
- Check Python version compatibility
- Install all required dependencies
- Set up environment configuration
- Run setup tests to verify everything works

### Option 2: Manual Installation

```bash
# 1. Install dependencies
pip install -r requirements.txt

# 2. Set up environment
cp .env.example .env

# 3. Edit .env file with your API keys
# Add your API keys to the .env file

# 4. Test the setup
python test_setup.py
```

## ⚙️ Configuration

### Environment Variables

Edit the `.env` file with your configuration:

```env
# Required: Add at least one API key
OPENAI_API_KEY=your_openai_key_here
ANTHROPIC_API_KEY=your_anthropic_key_here

# Optional: Customize settings
DEFAULT_PROVIDER=openai
MAX_SUGGESTIONS=5
DEBOUNCE_DELAY=300
CACHE_TTL=3600
```

### API Keys Setup

#### OpenAI API Key
1. Go to [OpenAI Platform](https://platform.openai.com/api-keys)
2. Create a new API key
3. Copy the key (starts with `sk-`)
4. Add to `.env` file: `OPENAI_API_KEY=sk-your-key-here`

#### Anthropic API Key
1. Go to [Anthropic Console](https://console.anthropic.com/)
2. Create a new API key
3. Copy the key (starts with `sk-ant-`)
4. Add to `.env` file: `ANTHROPIC_API_KEY=sk-ant-your-key-here`

## 🏃‍♂️ Running the Application

```bash
# Start the application
python app.py
```

The application will be available at: **http://localhost:7860**

## 🧪 Testing

### Run Setup Tests
```bash
python test_setup.py
```

### Run Unit Tests
```bash
# Install test dependencies (if not already installed)
pip install pytest pytest-cov

# Run all tests
python -m pytest tests/

# Run with coverage
python -m pytest tests/ --cov=src/
```

## 🔧 Troubleshooting

### Common Issues

#### Import Errors
```bash
# Make sure you're in the correct directory
cd Smart-Auto-Complete

# Install dependencies
pip install -r requirements.txt
```

#### API Key Issues
- Verify your API keys are correct and active
- Check that keys are properly set in `.env` file
- Ensure you have sufficient API credits

#### Port Already in Use
```bash
# If port 7860 is busy, specify a different port
python app.py --server-port 7861
```

#### Permission Errors
```bash
# On macOS/Linux, you might need:
python3 app.py

# Or use virtual environment:
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -r requirements.txt
python app.py
```

### Debug Mode

Enable debug mode for detailed logging:

```bash
# Set in .env file
DEBUG_MODE=true
LOG_LEVEL=DEBUG
```
