Conversation handling using python-bale-bot

[okaeiz]

In python-telegram-bot, handling conversations can be done through the steps below:

1. We define a function.

async def start(update: Update, context: ContextTypes.DEFAULT_TYPE) -> int:
    """Starts the conversation and asks the user about their gender."""
    reply_keyboard = [["Boy", "Girl", "Other"]]

    await update.message.reply_text(
        "Hi! My name is Professor Bot. I will hold a conversation with you. "
        "Send /cancel to stop talking to me.\n\n"
        "Are you a boy or a girl?",
        reply_markup=ReplyKeyboardMarkup(
            reply_keyboard, one_time_keyboard=True, input_field_placeholder="Boy or Girl?"
        ),
    )

    return GENDER

2. We define the 'states'.

GENDER, PHOTO, LOCATION, BIO = range(4)

3. Then we create the handler block.

def main() -> None:
    """Run the bot."""
    # Create the Application and pass it your bot's token.
    application = Application.builder().token("TOKEN").build()

    # Add conversation handler with the states GENDER, PHOTO, LOCATION and BIO
    conv_handler = ConversationHandler(
        entry_points=[CommandHandler("start", start)],
        states={
            GENDER: [MessageHandler(filters.Regex("^(Boy|Girl|Other)$"), gender)],
            PHOTO: [MessageHandler(filters.PHOTO, photo), CommandHandler("skip", skip_photo)],
            LOCATION: [
                MessageHandler(filters.LOCATION, location),
                CommandHandler("skip", skip_location),
            ],
            BIO: [MessageHandler(filters.TEXT & ~filters.COMMAND, bio)],
        },
        fallbacks=[CommandHandler("cancel", cancel)],
    )

    application.add_handler(conv_handler)

    # Run the bot until the user presses Ctrl-C
    application.run_polling()


if __name__ == "__main__":
    main()

Can we do such things here in this library too?

✨The complete reference of the codes above is here.

hey @okaeiz

I did not understand what you meant

Please clearly state what facilities are there in that library that you want to be in python-bale-bot.

[kian-ahmadian]

Two points are not observed in this code.

• In the bot.dispatch method, the method you write inside should be like this:

...
@bot.listen("on_message")
async def when_message(message):
    ...
    await message.reply("Your coffee will be ready soon.")
    bot.dispatch("my_custom_event", message.author)

@bot.listen("on_my_custom_event")
async def when_custom_event(client: bale.user):
    ....

You did not leave the on statement for the listener.

• Nowhere in the code did you wait for the callback sent by the user. Therefore, you should have used bot.wait_for before using bot.dispatch. And then you would send the callback value for that event.

[okaeiz]

Ah, quite. Thanks for that.
Therefore, my_custom_event which is passed to bot.dispatch() is the same as on_my_custom_event which is passed to @bot.listen()?
If they are both the event name, why aren't they identical?

[kian-ahmadian]

Yes. That's right.

This is the property of this package to make it easier to write and read the code, and on the beginning

[okaeiz]

what should be my wait_for line before bot.dispatch()?
Is it something like this?

await client.wait_for("callback")

[kian-ahmadian]

...
callback = await client.wait_for("callback", ...)
# it's After get callback and user click on a inline keyboard button
bot.dispatch("send_coffee", callback)

ok?
