## Quick Start

### Prerequisites

- Python 3.9+ (3.11+ recommended)
- Twitch account for the bot
- Perplexity API key

### Installation

```bash
# Clone the repository
git clone https://github.com/Kenearos/KI-Chat-Bot-Eugen.git
cd KI-Chat-Bot-Eugen

# Create virtual environment
python -m venv venv

# Activate virtual environment
# On Windows:
.\venv\Scripts\Activate.ps1
# On Linux/Mac:
source venv/bin/activate

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

### Configuration

#### Option 1: Setup Wizard (Recommended)
Run the interactive setup wizard to configure the bot:
```bash
python setup_wizard.py
```

The wizard will:
- Guide you through getting Twitch OAuth token
- Help you set up Perplexity API key
- Validate your credentials
- Create necessary directories and config files

#### Option 2: Manual Configuration
Copy `.env.example` to `.env` and fill in your credentials:
```bash
cp .env.example .env
```

Edit `.env` with your values:
```
TWITCH_OAUTH_TOKEN=oauth:your_token_here
TWITCH_BOT_NICKNAME=Eugen
TWITCH_CHANNEL=#your_channel_here
PERPLEXITY_API_KEY=pplx-your_key_here
```

#### Getting API Keys

**Twitch OAuth Token:**
1. Visit [twitchtokengenerator.com](https://twitchtokengenerator.com/)
2. Generate token with `chat:read` and `chat:edit` scopes
3. Copy the token (should start with `oauth:`)

**Perplexity API Key:**
1. Visit [perplexity.ai/api](https://www.perplexity.ai/api)
2. Sign up/Login
3. Generate new API key
4. Copy the key (should start with `pplx-`)

### Testing Credentials (Recommended)

Before running the bot, test your credentials:

```bash
python test_credentials.py
```

This will:
- Validate your Twitch OAuth token with detailed diagnostics
- Test your Perplexity API key and check model access
- Provide specific error messages and fixes for common issues
- Automatically detect if `sonar-pro` is unavailable and suggest `sonar` fallback

**Example output:**
```
✓ Twitch IRC:      PASS
✓ Perplexity API:  PASS
🎉 All credentials valid! Bot is ready to run.
```

### Running the Bot

```bash
python chatbot.py
```

The dashboard will open automatically showing live activity.

## Usage

Once running, the bot responds when mentioned in Twitch chat:

```
User: @Eugen what's the best class in WoW?
Eugen: @User The best class depends on your playstyle...

User: Eugen, how do I level my 3D printer?
Eugen: @User For bed leveling, start by...
```

- **eugen_claude.md**: Detailed German documentation with architecture and implementation details

## Development

The bot is built with:
- Python 3.9+
- Perplexity Sonar API for AI responses
- Twitch IRC for chat integration
- PySimpleGUI for dashboard
- Async/await for concurrent operations

## Troubleshooting

### Quick Diagnosis

**First step: Run the credential validator**
```bash
python test_credentials.py
```

This will identify exactly what's wrong and provide specific fixes.

### Common Issues

**Twitch OAuth Token Invalid:**
- ✗ Error: `Login authentication failed`
- **Fix:**
  1. Go to https://twitchtokengenerator.com
  2. Select "Bot Chat Token"
  3. Make sure you're logged in as the bot account
  4. Copy the new token (including `oauth:` prefix)
  5. Update `TWITCH_OAUTH_TOKEN` in `.env`

**Bot nickname mismatch:**
- Token must be generated by the same account as `TWITCH_BOT_NICKNAME`
- If bot nickname is `EugenBot`, you must be logged into Twitch as `EugenBot` when generating the token

**Perplexity Model Not Available:**
- ✗ Error: `400 Bad Request` or model not accessible
- **Fix:**
  - Your API key might not have access to `sonar-pro`
  - The setup wizard will automatically suggest `sonar` as fallback
  - Or manually change `PERPLEXITY_MODEL=sonar` in `.env`

**Bot doesn't respond in chat:**
- Run `python test_credentials.py` to verify credentials
- Check that bot is in the correct channel
- Check `logs/eugen.log` for errors
- Verify bot was mentioned correctly (`@Eugen` or `Eugen:`)

**IRC connection failed:**
- Check internet connection
- Verify firewall allows port 6667
- Run credential validator for detailed diagnostics

**API rate limits:**
- Check your Perplexity API credits at https://www.perplexity.ai/settings/api
- Enable `DEBUG_MODE=true` in `.env` for detailed API logs
