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

class ForceReply(ReplyMarkup):
    """
    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.

    Attributes:
        force_reply (:obj:`True`): Shows reply interface to the user, as if they manually selected
            the bot's message and tapped 'Reply'.
        selective (:obj:`bool`): Optional. Force reply from specific users only.

    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 text of the Message object.
            2) If the bot's message is a reply (has reply_to_message_id), sender of the
               original message.

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