🚀 Quick Start

Installation

pip install telegram-menu-builder

Basic Usage

from telegram import Update
from telegram.ext import Application, CallbackQueryHandler, ContextTypes
from telegram_menu_builder import MenuBuilder, MenuRouter

# Create a menu
async def show_settings(update: Update, context: ContextTypes.DEFAULT_TYPE) -> None:
    menu = (MenuBuilder()
        .add_item("🌍 Language", handler="set_language")
        .add_item("👤 Profile", handler="edit_profile")
        .add_item("🔔 Notifications", handler="notifications")
        .columns(2)
        .add_back_button()
        .build())
    
    await update.message.reply_text("⚙️ Settings", reply_markup=menu)

# Route callbacks
router = MenuRouter()

@router.handler("set_language")
async def handle_language(update: Update, context: ContextTypes.DEFAULT_TYPE, data: dict) -> None:
    # Handle language selection
    pass

# Register with application
app = Application.builder().token("YOUR_TOKEN").build()
app.add_handler(CallbackQueryHandler(router.route))

📚 Advanced Examples

Multi-Level Menus with Parameters

menu = (MenuBuilder()
    .add_item(
        "📝 Edit User",
        handler="edit_user",
        user_id=123,
        field="email",
        breadcrumb=["settings", "users"],
        validation_required=True
    )
    .add_item(
        "🗑️ Delete User",
        handler="delete_user",
        user_id=123,
        confirm=True
    )
    .columns(1)
    .add_back_button(handler="user_list", page=2)
    .build())

Submenu Navigation

# Main menu
main_menu = MenuBuilder()

# Create submenu
user_submenu = (MenuBuilder()
    .add_item("Add User", handler="add_user")
    .add_item("List Users", handler="list_users")
    .add_back_button())

# Add submenu to main menu
main_menu.add_submenu("👥 Users", user_submenu)

Custom Storage Backend

from telegram_menu_builder import StorageBackend, MenuBuilder
from redis.asyncio import Redis

class RedisStorage(StorageBackend):
    def __init__(self, redis_client: Redis) -> None:
        self.redis = redis_client
    
    async def set(self, key: str, data: dict, ttl: int) -> None:
        await self.redis.setex(key, ttl, json.dumps(data))
    
    async def get(self, key: str) -> dict | None:
        value = await self.redis.get(key)
        return json.loads(value) if value else None

# Use custom storage
storage = RedisStorage(redis_client)
builder = MenuBuilder(storage_manager=storage)

🏗️ Architecture

The library follows a clean architecture with separation of concerns:

MenuBuilder (API Layer)
    ↓
MenuAction (Data encoding/decoding)
    ↓
StorageManager (Strategy selection)
    ↓
StorageBackend (Interface)
    ├── MemoryStorage
    ├── RedisStorage
    └── SQLStorage

Callback Data Encoding

The library intelligently encodes callback data based on size:

1. Inline (< 60 bytes): Encoded directly in callback_data
2. Short-term (60-500 bytes): Stored in Redis/Memory with TTL
3. Persistent (> 500 bytes): Stored in database

# Automatic strategy selection
action = MenuAction(
    handler="complex_handler",
    params={
        "user_id": 123,
        "filters": {"active": True, "role": "admin"},
        "breadcrumb": ["main", "users", "edit"],
        "metadata": {...}
    }
)
# Library automatically chooses best storage strategy

🏗️ Architecture Highlights

Intelligent Callback Data Management

• Automatic Strategy Selection: Chooses between inline, short-term, and persistent storage
• Compression: Zlib compression for inline data
• Deduplication: Same data = same storage key
• 64-byte Limit: Automatically handles Telegram's callback_data constraint

Type Safety

• Pydantic v2: Runtime validation with static type support
• Pyright Strict: 100% type coverage with strict checking
• MyPy Compatible: Dual type checker validation
• Python 3.12+: Modern type hints (generics, Self, Protocol)

Storage Architecture

CallbackData → Encoder → Strategy Selector
                              ├─ Inline (< 60 bytes)
                              ├─ Short-term Storage (60-500 bytes, TTL)
                              └─ Persistent Storage (> 500 bytes)

🙏 Acknowledgments

• Built for python-telegram-bot v20+
• Inspired by real-world Telegram bot development challenges
• Type checking powered by Pyright
• Validation powered by Pydantic v2
