- aiogram 3.x

## 🚀 Installation

```bash
pip install aiogram-smart-messages
```

## 📚 Quick Start

### 1. Basic Setup

```python
from aiogram import Bot, Dispatcher
from aiogram.types import Message
from aiogram_smart_messages.message_engine import MessageEngine
from aiogram_smart_messages.renderer.bot_messages import SmartMessageRenderer
from aiogram_smart_messages.logger import get_logger

# Initialize bot and logger
bot = Bot(token="YOUR_BOT_TOKEN")
dp = Dispatcher()
logger = get_logger("my_bot")
engine = MessageEngine(bot)

# Send a simple message
@dp.message(commands=["start"])
async def cmd_start(message: Message):
    await SmartMessageRenderer.send(
        engine=engine,
        source=message,
        role="user",
        namespace="main",
        menu_file="welcome",
        block_key="greeting",
        lang="en",
        context={"username": message.from_user.first_name}
    )
```

### 2. JSON Message Structure

Create message files in your project structure:
```
my_bot/
├── main/
│   ├── messages/
│   │   ├── user/
│   │   │   ├── en/
│   │   │   │   └── welcome.json
│   │   │   └── ru/
│   │   │       └── welcome.json
```

Example `welcome.json`:
```json
{
  "greeting": {
    "text": "Hello, {username}! Welcome to our bot.",
    "buttons": [
      [
        {"type": "callback", "text": "Get Started", "data": "start"},
        {"type": "url", "text": "Help", "data": "https://example.com/help"}
      ],
      [
        {"type": "webapp", "text": "Open App", "data": "https://app.example.com"}
      ]
    ]
  },
  "main_menu": {
    "text": "Choose an option:",
    "photo": "menu_photo.jpg",
    "caption": "Main Menu",
    "buttons": [
      [
        {"type": "callback", "text": "Settings ⚙️", "data": "settings"},
        {"type": "callback", "text": "Profile 👤", "data": "profile"}
      ]
    ]
  }
}
```

### 3. Advanced Usage

#### Send with Context Variables

```python
from aiogram_smart_messages.decorators import with_error_logging

@with_error_logging(logger=logger, error_label="WELCOME_MESSAGE")
async def send_personalized_welcome(message: Message, user_data: dict):
    await SmartMessageRenderer.send(
        engine=engine,
        source=message,
        role="user",
        namespace="main",
        menu_file="welcome",
        block_key="greeting",
        lang=user_data.get("language", "en"),
        context={
            "username": user_data["name"],
            "balance": user_data["balance"],
            "level": user_data["level"]
        }
    )
```

#### Edit Messages

```python
from aiogram.types import CallbackQuery

@dp.callback_query(lambda c: c.data == "settings")
async def show_settings(callback: CallbackQuery):
    await SmartMessageRenderer.edit(
        engine=engine,
        source=callback,
        role="user",
        namespace="main",
        menu_file="settings",
        block_key="main",
        lang="en"
    )
    await callback.answer()
```

#### Smart Edit or Send

Automatically decides whether to edit or resend based on media content:

```python
@dp.callback_query(lambda c: c.data.startswith("view_"))
async def view_item(callback: CallbackQuery):
    item_id = callback.data.split("_")[1]
    
    await SmartMessageRenderer.smart_edit_or_send(
        engine=engine,
        source=callback,
        role="user",
        namespace="shop",
        menu_file="catalog",
        block_key="item_details",
        lang="en",
        context={"item_id": item_id}
    )
```

#### Reply to Messages

```python
@dp.message(lambda m: m.text and "help" in m.text.lower())
async def help_reply(message: Message):
    await SmartMessageRenderer.reply(
        engine=engine,
        source=message,
        role="user",
        namespace="main",
        menu_file="help",
        block_key="quick_help",
        lang="en"
    )
```

#### Send Documents

```python
from aiogram.types import FSInputFile

@dp.callback_query(lambda c: c.data == "download_report")
async def send_report(callback: CallbackQuery):
    doc = FSInputFile("reports/monthly_report.pdf")
    
    await SmartMessageRenderer.send_document(
        engine=engine,
        source=callback.message.chat.id,
        document=doc,
        caption="Your monthly report",
        custom_markup=None
    )
    await callback.answer("Report sent!")
```

### 4. Building Keyboards Manually

```python
from aiogram_smart_messages.builder import KeyboardBuilder

# Inline keyboard
inline_buttons = [
    [
        {"type": "callback", "text": "Option 1", "data": "opt1"},
        {"type": "callback", "text": "Option 2", "data": "opt2"}
    ],
    [
        {"type": "url", "text": "Visit Website", "data": "https://example.com"}
    ]
]
inline_kb = KeyboardBuilder.build_inline_keyboard(inline_buttons)

# Reply keyboard
reply_buttons = [
    [{"text": "Main Menu"}, {"text": "Settings"}],
    [{"type": "webapp", "text": "Open App", "data": "https://app.example.com"}]
]
reply_kb = KeyboardBuilder.build_reply_keyboard(
    reply_buttons,
    resize_keyboard=True,
    one_time_keyboard=True
)
```

### 5. Using Decorators

#### Error Logging Decorator

```python
from aiogram_smart_messages.decorators import with_error_logging

@with_error_logging(
    logger=logger,
    fallback=None,
    error_label="DATABASE_ERROR"
)
async def get_user_data(user_id: int):
    # Your database logic here
    data = await db.fetch_user(user_id)
    return data

# With re-raise for critical operations
@with_error_logging(
    logger=logger,
    reraise=True,
    error_label="CRITICAL_PAYMENT"
)
async def process_payment(amount: float):
    # Critical operation that should fail loudly
    await payment_gateway.charge(amount)
```

#### Retry Decorator

```python
from aiogram_smart_messages.decorators import with_retry

@with_retry(
    max_attempts=3,
    delay=1.0,
    backoff=2.0,
    logger=logger
)
async def fetch_external_api():
    # Will retry up to 3 times with exponential backoff
    response = await http_client.get("https://api.example.com/data")
    return response.json()
```

### 6. Logger Configuration

```python
from aiogram_smart_messages.logger import get_logger
import logging

# Basic logger
logger = get_logger("my_bot")

# Custom configuration
logger = get_logger(
    name="my_bot",
    level=logging.DEBUG,
    format_string="%(asctime)s - %(name)s - %(levelname)s - %(message)s"
)

# Use logger
logger.info("Bot started")
logger.warning("Rate limit approaching")
logger.error("Failed to send message")
logger.debug("Processing callback: %s", callback_data)
```

### 7. Advanced Features

#### Extra Keyboard Buttons

Add dynamic buttons to existing keyboard layouts:

```python
extra_buttons = [
    {"type": "callback", "text": "🔙 Back", "data": "back"}
]

await SmartMessageRenderer.send(
    engine=engine,
    source=message,
    role="user",
    namespace="main",
    menu_file="menu",
    block_key="main",
    lang="en",
    extra_kb=extra_buttons,
    extra_kb_position="bottom"  # or "top"
)
```

#### Override Block Data

Send messages without loading from JSON:

```python
custom_block = {
    "text": "Dynamic message",
    "buttons": [
        [{"type": "callback", "text": "OK", "data": "ok"}]
    ]
}

await SmartMessageRenderer.send(
    engine=engine,
    source=message,
    role="user",
    override_block=custom_block
)
```

#### Custom Keyboard Markup

Use your own pre-built keyboards:

```python
from aiogram.types import InlineKeyboardMarkup, InlineKeyboardButton

custom_keyboard = InlineKeyboardMarkup(inline_keyboard=[
    [InlineKeyboardButton(text="Custom", callback_data="custom")]
])

await SmartMessageRenderer.send(
    engine=engine,
    source=message,
    role="user",
    namespace="main",
    menu_file="menu",
    block_key="main",
    lang="en",
    custom_markup=custom_keyboard
)
```

## 🔧 Configuration

The library uses the following configuration structure:
- `module` - Top-level module name (default: "main_bot")
- `namespace` - Feature namespace (e.g., "main", "admin_panel", "shop")
- `role` - User role (e.g., "user", "admin", "common")
- `lang` - Language code (e.g., "en", "ru", "es")

## 🐛 Error Handling

The library provides comprehensive error handling with clear labels:

```python
# Labels used in SmartMessageRenderer:
# - SEND_SMART_MESSAGE
# - EDIT_SMART_MESSAGE  
# - REPLY_SMART_MESSAGE
# - SEND_DOCUMENT

# Custom error handling
@with_error_logging(
    logger=logger,
    fallback={"status": "error"},
    error_label="CUSTOM_OPERATION"
)
async def my_operation():
    # Your code here
    pass
```
