"""
|
|
Returns an iterator over the dialogs, yielding 'limit' at most.
|
|
Dialogs are the open "chats" or conversations with other people,
|
|
groups you have joined, or channels you are subscribed to.
|
|
|
|
Args:
|
|
limit (`int` | `None`):
|
|
How many dialogs to be retrieved as maximum. Can be set to
|
|
``None`` to retrieve all dialogs. Note that this may take
|
|
whole minutes if you have hundreds of dialogs, as Telegram
|
|
will tell the library to slow down through a
|
|
``FloodWaitError``.
|
|
|
|
offset_date (`datetime`, optional):
|
|
The offset date to be used.
|
|
|
|
offset_id (`int`, optional):
|
|
The message ID to be used as an offset.
|
|
|
|
offset_peer (:tl:`InputPeer`, optional):
|
|
The peer to be used as an offset.
|
|
|
|
ignore_migrated (`bool`, optional):
|
|
Whether :tl:`Chat` that have ``migrated_to`` a :tl:`Channel`
|
|
should be included or not. By default all the chats in your
|
|
dialogs are returned, but setting this to ``True`` will hide
|
|
them in the same way official applications do.
|
|
|
|
_total (`list`, optional):
|
|
A single-item list to pass the total parameter by reference.
|

Yields:

Creates a `Conversation <telethon.tl.custom.conversation.Conversation>`

with the given entity so you can easily send messages and await for
|
|
responses or other reactions. Refer to its documentation for more.
|
|
|
|
Args:
|
|
entity (`entity`):
|
|
The entity with which a new conversation should be opened.
|
|
|
|
timeout (`int` | `float`, optional):
|
|
The default timeout *per action* to be used. You
|
|
can override this on each action. By default there
|
|
is no per-action time limit but there is still a
|
|
`total_timeout` for the entire conversation.
|
|
|
|
total_timeout (`int` | `float`, optional):
|
|
The total timeout to use for the whole conversation.
|
|
After these many seconds pass, subsequent actions
|
|
will result in ``asyncio.TimeoutError``.
|
|
|
|
max_messages (`int`, optional):
|
|
The maximum amount of messages this conversation will
|
|
remember. After these many messages arrive in the
|
|
specified chat, subsequent actions will result in
|
|
``ValueError``.
|
|
|
|
exclusive (`bool`, optional):
|
|
By default, conversations are exclusive within a single
|
|
chat. That means that while a conversation is open in a
|
|
chat, you can't open another one in the same chat, unless
|
|
you disable this flag.
|
|
|
|
If you try opening an exclusive conversation for
|
|
a chat where it's already open, it will raise
|
|
``AlreadyInConversationError``.
|
|
|
|
replies_are_responses (`bool`, optional):
|
|
Whether replies should be treated as responses or not.
|
|
|
|
If the setting is enabled, calls to `conv.get_response
|
|
<telethon.tl.custom.conversation.Conversation.get_response>`
|
|
and a subsequent call to `conv.get_reply
|
|
<telethon.tl.custom.conversation.Conversation.get_reply>`
|
|
will return different messages, otherwise they may return
|
|
the same message.
|
|
|
|
Consider the following scenario with one outgoing message,
|
|
1, and two incoming messages, the second one replying::
|
|
|
|
Hello! <1
|
|
2> (reply to 1) Hi!
|
|
3> (reply to 1) How are you?
|
|

|

|
.. code-block:: python
|
|

|
async with client.conversation(chat) as conv:

|
msg1 = await conv.send_message('Hello!')
|
|
msg2 = await conv.get_response()
|
|
msg3 = await conv.get_reply()
|
|
|
|
With the setting enabled, ``msg2`` will be ``'Hi!'`` and
|
|
``msg3`` be ``'How are you?'`` since replies are also
|
|
responses, and a response was already returned.
|
|
|
|
With the setting disabled, both ``msg2`` and ``msg3`` will
|
|
be ``'Hi!'`` since one is a response and also a reply.

A `Conversation <telethon.tl.custom.conversation.Conversation>`.
