Extract bot name from a command

[vehlwn]

1. pyTelegramBotAPI 4.15.3
2. Arch Linux
3. Python 3.11.6

Is there any way to filter messages by bot tag like /get@botName? For now I'm registering my commands with bot.register_message_handler(help_handler, commands=["help"]) and when there are multiple bots in a group command /help@other_bot triggers @other_bot as well as my bot. I've found functions extract_arguments and extract_command in telebot.util module, bot no function to extract mentioned bot name from a command (https://pytba.readthedocs.io/en/latest/util.html#telebot.util.extract_arguments).

PS: I think it's more of a bug than discussion because teloxide in Rust and telegraf in NodeJS do have bot name parsing enabled in commands out of the box.

I managed to make a temporary solution but I want this to be a built in feature.

import telebot.async_telebot
import telebot.asyncio_filters

bot = telebot.async_telebot.AsyncTeleBot(TOKEN)

class MatchBotUsernameFilter(telebot.asyncio_filters.SimpleCustomFilter):
    key = "match_bot_username"

    def __init__(self, bot_name: str) -> None:
        super().__init__()
        self.bot_name = bot_name

    async def check(self, message: telebot.types.Message) -> bool:
        text = message.text or ""
        words = text.split(maxsplit=1)
        full_command = words[0].split("@")
        if len(full_command) >= 2:
            bot_username = full_command[1]
            return bot_username == self.bot_name
        return True

@bot.message_handler(commands=["help"], match_bot_username=True)
async def start_message(message):
    await bot.reply_to(message, "Show this message")

async def main():
    me = await bot.get_me()
    if me.username is None:
        raise RuntimeError("Bot must have username")
    bot_name = me.username
    bot.add_custom_filter(MatchBotUsernameFilter(bot_name))
    await bot.infinity_polling()

if __name__ == "__main__":
    asyncio.run(main())
