## 🚀 Quick Start

### Installation

**Basic Installation:**
```bash
pip install mem-llm
```

**With Optional Dependencies:**
```bash
# PostgreSQL support
pip install mem-llm[postgresql]

# MongoDB support
pip install mem-llm[mongodb]

# All database support (PostgreSQL + MongoDB)
pip install mem-llm[databases]

# All optional features
pip install mem-llm[all]
```

**Upgrade:**
```bash
pip install -U mem-llm
```

### Prerequisites

**Choose one of the following LLM backends:**

#### Option 1: Ollama (Local, Privacy-First)
```bash
# Install Ollama (visit https://ollama.ai)
# Then pull a model
ollama pull granite4:tiny-h

# Start Ollama service
ollama serve
```

#### Option 2: LM Studio (Local, GUI-Based)
```bash
# 1. Download and install LM Studio: https://lmstudio.ai
# 2. Download a model from the UI
# 3. Start the local server (default port: 1234)
```

### Basic Usage

```python
from mem_llm import MemAgent

# Option 1: Use Ollama (default)
agent = MemAgent(model="granite4:3b")

# Option 2: Use LM Studio
agent = MemAgent(backend='lmstudio', model='local-model')

# Option 3: Auto-detect available backend
agent = MemAgent(auto_detect_backend=True)

# Set user and chat (same for all backends!)
agent.set_user("alice")
response = agent.chat("My name is Alice and I love Python!")
print(response)

# Memory persists across sessions
response = agent.chat("What's my name and what do I love?")
print(response)  # Agent remembers: "Your name is Alice and you love Python!"
```

That's it! Just 5 lines of code to get started with any backend.

### Function Calling / Tools (v2.0.0+) 🛠️

Enable agents to perform actions using external tools:

```python
from mem_llm import MemAgent, tool

# Enable built-in tools
agent = MemAgent(model="granite4:3b", enable_tools=True)
agent.set_user("alice")

# Agent can now use tools automatically!
agent.chat("Calculate (25 * 4) + 10")  # Uses calculator tool
agent.chat("What is the current time?")  # Uses time tool
agent.chat("Count words in 'Hello world from AI'")  # Uses text tool

# Create custom tools
@tool(name="greet", description="Greet a user by name")
def greet_user(name: str) -> str:
    return f"Hello, {name}! 👋"

# Register custom tools
agent = MemAgent(enable_tools=True, tools=[greet_user])
agent.chat("Greet John")  # Agent will call your custom tool
```

**Built-in Tools (18+ total):**
- **Math**: `calculate` - Evaluate math expressions
- **Text**: `count_words`, `reverse_text`, `to_uppercase`, `to_lowercase`
- **File**: `read_file`, `write_file`, `list_files`
- **Utility**: `get_current_time`, `create_json`
- **Memory** *(v2.0)*: `search_memory`, `get_user_info`, `list_conversations`
- **Async** *(v2.1)*: `fetch_url`, `post_json`, `read_file_async`, `write_file_async`, `async_sleep`

**Memory Tools** allow agents to access their own conversation history:
```python
agent.chat("Search my memory for 'Python'")  # Finds past conversations
agent.chat("What's my user info?")  # Gets user profile
agent.chat("Show my last 5 conversations")  # Lists recent chats
```

### Tool Validation (v2.1.0+) ✅

Add input validation to your custom tools:

```python
from mem_llm import tool

# Email validation with regex pattern
@tool(
    name="send_email",
    pattern={"email": r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'},
    min_length={"email": 5, "subject": 1},
    max_length={"email": 254, "subject": 100}
)
def send_email(email: str, subject: str) -> str:
    return f"Email sent to {email}"

# Range validation for numbers
@tool(
    name="set_volume",
    min_value={"volume": 0},
    max_value={"volume": 100}
)
def set_volume(volume: int) -> str:
    return f"Volume set to {volume}"

# Choice validation (enum-like)
@tool(
    name="set_language",
    choices={"lang": ["python", "javascript", "rust", "go"]}
)
def set_language(lang: str) -> str:
    return f"Language: {lang}"

# Custom validator function
def is_even(x: int) -> bool:
    return x % 2 == 0

@tool(name="process_even", validators={"number": is_even})
def process_even(number: int) -> str:
    return f"Processed: {number}"
```

### Async Tools (v2.1.0+) 🚀

Create async tools for non-blocking I/O:

```python
import asyncio
from mem_llm import tool

# Async tool for HTTP requests
@tool(name="fetch_data", description="Fetch data from API")
async def fetch_data(url: str) -> str:
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            return await response.text()

# Async file operations
@tool(name="process_file", description="Process large file")
async def process_large_file(filepath: str) -> str:
    async with aiofiles.open(filepath, 'r') as f:
        content = await f.read()
    return f"Processed {len(content)} bytes"

# Agent automatically handles async tools
agent = MemAgent(enable_tools=True, tools=[fetch_data, process_large_file])
agent.chat("Fetch data from https://api.example.com/data")
```

### Streaming Response (v1.3.3+) ⚡

Get real-time responses with ChatGPT-style typing effect:

```python
from mem_llm import MemAgent

agent = MemAgent(model="granite4:tiny-h")

# Stream response in real-time
for chunk in agent.chat_stream("Python nedir ve neden popülerdir?"):
    print(chunk, end='', flush=True)
```

### REST API Server (v1.3.3+) 🌐

### Memory Search & Export
Powerful memory management:

```python
# Search across all memories
results = agent.search_memories("python", limit=5)

# Export everything
data = agent.export_user_data()

# Get insights
stats = agent.get_memory_stats()
```
