aiokilogram
Convenience tools and wrappers for aiogram
,
the asynchronous Telegram Bot API framework.
Installation
pip install aiokilogram
Basic Examples
Class-Based Command Handlers
The aiokilogram
toolkit is centered around the notion of class-based
command handlers. Basically this means that you can group several commands
as methods in a class and assign them to message and callback patterns
at class level.
Handler classes look something like this:
from aiokilogram.handler import CommandHandler
class TestCommandHandler(CommandHandler):
async def test_handler(self, event) -> None:
await self.send_text(user_id=event.from_user.id, text=f'This is a test reply')
# other related commands go here
def register(self, dispatcher) -> None:
dispatcher.register_message_handler(self.test_handler, commands={'hello'})
# register other commands here
The whole bot application will then be run like this:
import asyncio
import os
from aiokilogram.bot import KiloBot
from aiokilogram.settings import BaseGlobalSettings
class TestBot(KiloBot):
def register(self, bot, dispatcher) -> None:
TestCommandHandler(global_settings=self._global_settings, bot=bot).register(dispatcher)
# other command handlers can be added here
def run_bot():
bot = TestBot(global_settings=BaseGlobalSettings(
tg_bot_token=os.environ['TG_BOT_TOKEN']
))
asyncio.run(bot.run())
if __name__ == '__main__':
run_bot()
For more info you can take a look at a simple boilerplate bot
Set the TG_BOT_TOKEN
env variable to run it.
Action Buttons
The package also provides a simplified mechanism of using buttons and binding handlers to their callbacks. This is useful when you want your buttons to contain a combination of several parameters and don't want to implement their serialization, deserialization and callback bindings each time.
The idea is simple.
- Define an action (a
CallbackAction
subclass) using a combination of fields:
from enum import Enum
from aiokilogram.action import CallbackAction, StringActionField, EnumActionField
class ActionType(Enum):
show_recipe = 'show_recipe'
like_recipe = 'like_recipe'
class SingleRecipeAction(CallbackAction):
action_type = EnumActionField(enum_cls=ActionType)
recipe_title = StringActionField()
- Create a page containing action buttons:
from aiokilogram.page import ActionMessageButton, MessagePage, MessageBody, MessageKeyboard
page = MessagePage(
body=MessageBody(text='Main Recipe Menu'),
keyboard=MessageKeyboard(buttons=[
ActionMessageButton(
text='Button Text',
action=SingleRecipeAction(
action_type=ActionType.show_recipe,
recipe_title='Fantastic Menemen',
),
),
# ...
])
)
- Send it as a response to some command in your handler class:
await self.send_message_page(user_id=event.from_user.id, page=page)
- Bind a method to this action class in the
register
method of the handler class:
dispatcher.register_callback_query_handler(
self.action_handler_method, action=SingleRecipeAction,
)
or you can be more precise and limit the binding to specific values of the action's fields:
dispatcher.register_callback_query_handler(
self.action_handler_method,
action=ListRecipesAction.when(action_type=ActionType.like_recipe),
)
- Deserialize the action parameters in the handler method:
action = SingleRecipeAction.deserialize(query.data)
if 'soup' in action.recipe_title.lower():
do_soup_stuff() # whatever
See boilerplate bot with buttons
Set the TG_BOT_TOKEN
env variable to run it.
