Date Selection tool for Telegram Bots

A simple inline calendar for Telegram bots written in Python using python-telegram-bot. Based on calendar-telegram.

Description

The file telegramcalendar.py proved the API to create an inline keyboard for a Telegram Bot. The user can either select a date or move to the next or previous month by clicking a singe button.

Internals

The file telegramcalendar.py provides the user with two methods:

• create_calendar: This method returns a InlineKeyboardMarkup object with the calendar in the provided year and month.
• process_calendar_selection: This method can be used inside a CallbackQueryHandler method to check if the user has selected a date or wants to move to a different month. It also creates a new calendar with the same text if necessary.

Usage

To use the telecram-calendar-keyboard you need to have python-telegram-bot installed first. A full working example on how to use telegram-calendar-keyboard is provided in bot_example.py. As you can see below, you create a calendar and add it to a message with a reply_markup parameter and then you can process it in a callbackqueyhandler method using the process_calendar_selection method:

def calendar_handler(bot,update):
    update.message.reply_text("Please select a date: ",
                        reply_markup=telegramcalendar.create_calendar())


def inline_handler(bot,update):
    selected,date = telegramcalendar.process_calendar_selection(bot, update)
    if selected:
        bot.send_message(chat_id=update.callback_query.from_user.id,
                        text="You selected %s" % (date.strftime("%d/%m/%Y")),
                        reply_markup=ReplyKeyboardRemove())
