Installation
Common installation:
pip install -U reaction

Getting started
consumer.py:
import asyncio
from typing import List, Any
from reaction.rpc import RabbitRPC


class rpc(RabbitRPC):
URL = 'amqp://user:password@host'


@rpc()
def sync_square(*values) -> List[float]:
return [v ** 2 for v in values]


@rpc()
async def async_square(*values) -> List[float]:
await asyncio.sleep(1)
return [v ** 2 for v in values]


if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.create_task(sync_square.consume())
loop.create_task(async_square.consume())
loop.run_forever()

client.py:
import asyncio
from consumer import sync_square, async_square

if __name__ == '__main__':
loop = asyncio.get_event_loop()
x = loop.run_until_complete(sync_square.call(2, 3))
y = loop.run_until_complete(async_square.call(4, 5, 6))
print(x) # 4, 9
print(y) # 16, 25, 36
loop.close()

Telegram bot is ready to classify ants & bees, but you have to send files "as a photo"

Telegram bot quick howto
Install async telegram client first:
$ pip install aiotg

Then create your bot:
tgbot.py
from consumer import async_square
from aiotg import Bot, Chat

bot = Bot(api_token='telegram bot token goes here')


@bot.command('/start')
async def start(chat: Chat, match):
return chat.reply('Send me /square command with one float argument')


@bot.command(r"/square (.+)")
async def square_command(chat: Chat, match):
val = match.group(1)
try:
val = float(val)
square = await async_square.call(val)
resp = f'Square for {val} is {square}'
except:
resp = 'Invalid number'
return chat.reply(resp)


bot.run()
