"""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:: 20.0
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;
:tg-const:`telegram.ForceReply.MIN_INPUT_FIELD_PLACEHOLDER`-
:tg-const:`telegram.ForceReply.MAX_INPUT_FIELD_PLACEHOLDER`
characters.
.. versionadded:: 13.7
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.
