Receive a desktop notification when a steemmonster opponent is matched

Waiting at the seeking enemy screen of steemmonsters is quite boring, and when I get distracted, I will lose due to timeout...

Installation

You need beem:

pip install beem

For windows:

pip install win10toast

and for mac:

pip install pync

It should work out of the box for linux (notify-send must be available).

Store the following script as sm_opponent_ready.py:

from beem.blockchain import Blockchain
from beem.nodelist import NodeList
from beem.account import Account
import requests
from beem import Steem
import json
import os
import platform
import subprocess
from time import sleep
import argparse

app_name = 'sm-notifier'

is_mac = platform.system().lower() == 'darwin'
is_win = platform.system().lower() == 'windows'
if is_mac:
    from pync import notify as mac_notify
if is_win:
    from win10toast import ToastNotifier
    toaster = ToastNotifier()


def notify(msg, link=None):
    """Platform agnostic notifier"""
    if is_mac:
        mac_notify("", title=msg, open=link)
    elif is_win:
        toaster.show_toast(app_name, msg)
    else:
        subprocess.run(['notify-send', app_name, msg])

            if current_block > submit_expiration_block_num:
                error_occured = True  

and run it with

python sm_opponent_ready.py holger80

Replace holger80 with your account name.

When python 3.x is installed, pip and python may be replayed by pip3 and python3.

You will now get a notification, when an opponent is found and you will be reminded when you did not select a team yet.

The script scans new blocks for custom_json transaction with a sm_find_match id. When one is found, the https://steemmonsters.com/battle/status?id= API is asked if an opponent was matched. The API data are requested in a loop, until both opponents submitted a team.

Please let me know if you find this script useful and If I can improve something on it.
