gnome applet to track crypto prices

13 June 2021

add more FOMO to your life by constantly showing crypto prices as an applet. Wrote a small gnome applet to keep track of prices :)

Building applet

from gi.repository import Gtk as gtk
from gi.repository import AppIndicator3 as appindicator
import signal
from threading import Thread

APPINDICATOR_ID = "my-crypto-tracker"

def main():
    indicator = appindicator.Indicator.new(
        APPINDICATOR_ID,
        os.path.abspath("crypto.svg"),
        appindicator.IndicatorCategory.SYSTEM_SERVICES,
    )
    indicator.set_status(appindicator.IndicatorStatus.ACTIVE)
    indicator.set_menu(build_menu())
    gtk.main()

def build_menu():
    menu = gtk.Menu()
    item_quit = gtk.MenuItem("Quit")
    menu.append(item_quit)
    menu.show_all()
    return menu

def quit(source):
    notify.uninit()
    gtk.main_quit()

if __name__ == "__main__":
    signal.signal(signal.SIGINT, signal.SIG_DFL)

API to track crypto prices

I usually use bitbns as the source

CRYPTO_PRICE_ENDPOINT = "https://bitbns.com/order/getTickerWithVolume/"
def fetch_prices(coin_symbol):
    response = requests.get(CRYPTO_PRICE_ENDPOINT)
    response_to_json = response.json()
    coin_price = response_to_json[coin_symbol]["last_traded_price"]
    return coin_price

Update ticker to the applet

use indicator.set_label(your_thread) to keep updating the ticker
