"""This module contains an object that represents a Telegram ForceReply."""

class ForceReply(TelegramObject):
    """
    Upon receiving a message with this object, Telegram clients will display a reply interface to
    the user (act as if the user has selected the bot's message and tapped 'Reply'). This can be
    extremely useful if you want to create user-friendly step-by-step interfaces without having
    to sacrifice privacy mode.

    Objects of this class are comparable in terms of equality. Two objects of this class are
    considered equal, if their :attr:`selective` is equal.

    .. versionchanged:: 14.0
        The (undocumented) argument ``force_reply`` was removed and instead :attr:`force_reply`
        is now always set to :obj:`True` as expected by the Bot API.

    Args:
        selective (:obj:`bool`, optional): Use this parameter if you want to force reply from
            specific users only. Targets:

            1) Users that are @mentioned in the :attr:`~telegram.Message.text` of the
               :class:`telegram.Message` object.
            2) If the bot's message is a reply (has ``reply_to_message_id``), sender of the
               original message.

        input_field_placeholder (:obj:`str`, optional): The placeholder to be shown in the input
            field when the reply is active; 1-64 characters.

            .. versionadded:: 13.7

        **kwargs (:obj:`dict`): Arbitrary keyword arguments.

    Attributes:
        force_reply (:obj:`True`): Shows reply interface to the user, as if they manually selected
            the bots message and tapped 'Reply'.
        selective (:obj:`bool`): Optional. Force reply from specific users only.
        input_field_placeholder (:obj:`str`): Optional. The placeholder shown in the input
            field when the reply is active.
