My Elements of Quantum Computing professor gave us .pptx slides.
me: cringe bro
me: ok np, libreoffice --headless --convert-to pdf:writer_pdf_Export slides.pptx to the rescue
always me: no way, I'm too lazy let's write a Telegram bot
the Telegram bot:
from telegram.ext import Filters, MessageHandler, Updater
import subprocess
import os
TELEGRAM_TOKEN = os.environ["TELEGRAM_TOKEN"]
def convert(file):
cmd = f"libreoffice --headless --convert-to pdf:writer_pdf_Export {file} "
process = subprocess.Popen(cmd.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
def d(update, context):
context.bot.get_file(update.message.document).download()
with open("/tmp/slides.pptx", 'wb') as f:
context.bot.get_file(update.message.document).download(out=f)
def main():
u = Updater(TELEGRAM_TOKEN)
u.dispatcher.add_handler(MessageHandler(Filters.document, d))
u.start_polling()
u.idle()
if __name__ == '__main__':
main()
telegram api: telegram.error.BadRequest: File is too big
me: oh shit, how big this .pptx can be?
Oh, it's that fuckin big!!!
