Features

• 🚀 Easy to use - Simple decorator-based API
• 🔧 Type-safe - Full type hints and Pydantic validation
• 🎯 Command system - Built-in command handling with regex validation
• ⌨️ Custom keyboards - Dynamic keyboard generation and management
• 📨 Message handling - Flexible message processing system
• 🔄 WebSocket support - Real-time communication with RosChat server

• 📝 Logging - Built-in logging with configurable levels

Installation

From PyPI (when published)

pip install python-roschat-bot

From source

git clone https://github.com/yourusername/python-roschat-bot.git
cd python-roschat-bot
pip install -e .

Quick Start

1. Environment Configuration

First, create a .env file in your project root with the following configuration:

# Copy the example file
cp .env.example .env

Then edit .env with your bot credentials:

TOKEN=your_bot_token_here_minimum_64_characters_long
BASE_URL=https://your-roschat-server.com
BOT_NAME=YourBotName
QUERY=type-bot
REJECT_UNAUTHORIZED=false
KEYBOARD_COLS=3

2. Basic Bot Setup

import logging
from python_roschat_bot import RosChatBot, EventOutcome

# Configure logging
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

# Initialize the bot
bot = RosChatBot(logger=logger)

# Connect to the server (REQUIRED before registering handlers)
bot.connect()

# Register your handlers here...

# Start the bot (REQUIRED to begin processing messages)
bot.start_polling()

Core Concepts

Handler Functions Structure

All handler functions must follow this structure:

def your_handler(incoming: EventOutcome, bot: RosChatBot) -> None:
    # Your logic here
    pass

Decorators

The library provides three main decorators for different types of interactions:

1. Command Handler (@bot.command)

Handles slash commands (e.g., /start, /help):

@bot.command('/start')
def handle_start_command(incoming: EventOutcome, bot: RosChatBot) -> None:
    bot.send_message(incoming.cid, "Welcome! Use /help for available commands.")

@bot.command('/help')
def handle_help_command(incoming: EventOutcome, bot: RosChatBot) -> None:
    help_text = """
Available commands:
/start - Start the bot
/help - Show this help message
/keyboard - Show custom keyboard
    """
    bot.send_message(incoming.cid, help_text)

2. Message Handler (@bot.message)

Handles all incoming messages (except commands):

@bot.message()
def handle_all_messages(incoming: EventOutcome, bot: RosChatBot) -> None:
    if incoming.data and incoming.data.text:
        bot.send_message(incoming.cid, f"You said: {incoming.data.text}")

3. Button Handler (@bot.button)

Handles custom keyboard button presses:

@bot.button(['option1', 'option2', 'option3'])
def handle_button_press(incoming: EventOutcome, bot: RosChatBot) -> None:
    button_name = incoming.callback_data
    bot.send_message(incoming.cid, f"You pressed: {button_name}")

Bot Methods

Message Operations

bot.send_message(cid: int, data: str | dict, callback: Callable = None)

Sends a message to a specific chat.

# Send text message
bot.send_message(incoming.cid, "Hello, world!")

# Send structured data
bot.send_message(incoming.cid, {
    "type": "text",
    "content": "Formatted message"
})

bot.mark_message_received(msg_id: int, callback: Callable = None)

Marks a message as received (read receipt).

bot.mark_message_received(incoming.id)

bot.mark_message_watched(msg_id: int, callback: Callable = None)

Marks a message as watched (seen receipt).

bot.mark_message_watched(incoming.id)

bot.message_delete(msg_id: int, callback: Callable = None)

Deletes a specific message.

bot.message_delete(incoming.id)

Keyboard Operations

bot.turn_on_keyboard(cid: int, callback: Callable = None)

Shows the custom keyboard for a chat.

@bot.command('/keyboard')
def show_keyboard(incoming: EventOutcome, bot: RosChatBot) -> None:
    bot.turn_on_keyboard(incoming.cid)
    bot.send_message(incoming.cid, "Keyboard activated!")

bot.turn_off_keyboard(cid: int, callback: Callable = None)

Hides the custom keyboard for a chat.

@bot.command('/hide_keyboard')
def hide_keyboard(incoming: EventOutcome, bot: RosChatBot) -> None:
    bot.turn_off_keyboard(incoming.cid)
    bot.send_message(incoming.cid, "Keyboard hidden!")

Complete Example

import logging
from python_roschat_bot import RosChatBot, EventOutcome

# Configure logging
logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)
logger = logging.getLogger(__name__)

# Initialize bot
bot = RosChatBot(logger=logger)

# Connect to server (REQUIRED)
bot.connect()

# Command handlers
@bot.command('/start')
def start_command(incoming: EventOutcome, bot: RosChatBot) -> None:
    bot.send_message(incoming.cid, "Welcome! I'm your RosChat bot.")
    bot.turn_on_keyboard(incoming.cid)

@bot.command('/help')
def help_command(incoming: EventOutcome, bot: RosChatBot) -> None:
    help_text = """
Available commands:
/start - Start the bot and show keyboard
/help - Show this help message
/status - Show bot status

Available buttons:
- Info: Get bot information
- Settings: Bot settings
- Contact: Contact support
    """
    bot.send_message(incoming.cid, help_text)

@bot.command('/status')
def status_command(incoming: EventOutcome, bot: RosChatBot) -> None:
    status = f"""
Bot Status:
- Connected: ✅
- Commands registered: {len(bot.command_registry)}
- Buttons registered: {len(bot._button_registry)}
    """
    bot.send_message(incoming.cid, status)

# Button handlers
@bot.button(['info', 'settings', 'contact'])
def handle_buttons(incoming: EventOutcome, bot: RosChatBot) -> None:
    button = incoming.callback_data
    
    if button == 'info':
        bot.send_message(incoming.cid, "I'm a RosChat bot created with python-roschat-bot library!")
    elif button == 'settings':
        bot.send_message(incoming.cid, "Settings panel (not implemented yet)")
    elif button == 'contact':
        bot.send_message(incoming.cid, "Contact: [e-mail]")

# Message handler (handles all non-command messages)
@bot.message()
def handle_messages(incoming: EventOutcome, bot: RosChatBot) -> None:
    if incoming.data and incoming.data.text:
        # Echo the message back
        bot.send_message(incoming.cid, f"You said: {incoming.data.text}")
        
        # Mark as received
        if incoming.id:
            bot.mark_message_received(incoming.id)

# Start the bot (REQUIRED)
bot.start_polling()

Error Handling

The library provides a comprehensive exception hierarchy:

from python_roschat_bot import (
    RosChatBotError,
    AuthorizationError,
    BotConnectionError,
    InvalidDataError,
    WebSocketPortError
)

try:
    bot.connect()
except AuthorizationError as e:
    print(f"Authorization failed: {e}")
except BotConnectionError as e:
    print(f"Connection failed: {e}")
except WebSocketPortError as e:
    print(f"WebSocket port error: {e}")
