### Configuration

PYR uses environment variables for configuration:

```bash
# OpenAI Configuration
export R_MODEL="gpt-4o-mini"
export R_BASE_URL="https://api.openai.com"
export R_KEY="sk-[your-key]"
export R_PROVIDER="openai"

# Claude Configuration
export R_MODEL="claude-3-5-haiku-20241022"
export R_BASE_URL="https://api.anthropic.com"
export R_KEY="sk-ant-[your-key]"
export R_PROVIDER="anthropic"

# Ollama Configuration
export R_MODEL="qwen2.5:3b"
export R_BASE_URL="https://ollama.molodetz.nl"
export R_PROVIDER="ollama"

# Grok Configuration
export R_MODEL="grok-2"
export R_BASE_URL="https://api.x.ai"
export R_KEY="xai-[your-key]"
export R_PROVIDER="grok"
```

Or use a `.env` file:

```env
R_PROVIDER=openai
R_MODEL=gpt-4o-mini
R_KEY=sk-your-api-key
R_BASE_URL=https://api.openai.com
R_VERBOSE=true
R_SYNTAX_HIGHLIGHT=true
R_USE_TOOLS=true
```

## 📖 Usage Examples

### Interactive REPL

```bash
pyr
```

The REPL provides a rich interactive experience:

```
> help me write a Python function to sort a list
> !tools  # List available tools
> !models  # Show current model info
> !config  # Show configuration
> !exit  # Exit REPL
```

### AI Provider Examples

```bash
# Use OpenAI
pyr --provider openai --model gpt-4o-mini "explain async/await"

# Use Claude
pyr --provider anthropic --model claude-3-5-haiku-20241022 "review this code"

# Use Ollama (local)
pyr --provider ollama --model qwen2.5:3b "help with debugging"

# Use Grok
pyr --provider grok --model grok-2 "write unit tests"
```

### Context and File Integration

```bash
# Load context from file
pyr --context project-context.txt "analyze the architecture"

# Include Python files
pyr --py main.py --py utils.py "find potential bugs"

# Multiple contexts
pyr --context context1.txt --context context2.txt "compare approaches"
```

### Tool Integration Examples

The AI can automatically use tools when enabled:

- **File Operations**: Read/write files, create directories, glob patterns
- **Terminal Commands**: Execute shell commands safely
- **Web Search**: Search for information and news
- **Database Operations**: Store/retrieve key-value data
- **Python Execution**: Run Python code snippets
- **Code Search**: Search through indexed source code

Example conversation:
```
> Create a new Python file called hello.py with a greeting function

AI will use the write_file tool to create the file with proper content.

> Search for recent news about Python

AI will use the web_search_news tool to find current Python news.

> Execute this Python code: print("Hello from PYR!")

AI will use the python_execute tool to run the code and show output.
```
