|
|
Iterator over the messages for the given chat.
|
|
|
|
If either `search`, `filter` or `from_user` are provided,
|
|
:tl:`messages.Search` will be used instead of :tl:`messages.getHistory`.
|
|
|
|
.. note::
|
|
|
|
Telegram's flood wait limit for :tl:`GetHistoryRequest` seems to
|
|
be around 30 seconds per 10 requests, therefore a sleep of 1
|
|
second is the default for this limit (or above).
|
|
|
|
Arguments
|
|
entity (`entity`):
|
|
The entity from whom to retrieve the message history.
|
|
|
|
It may be ``None`` to perform a global search, or
|
|
to get messages by their ID from no particular chat.
|
|
Note that some of the offsets will not work if this
|
|
is the case.
|
|
|
|
Note that if you want to perform a global search,
|
|
you **must** set a non-empty `search` string.
|
|
|
|
limit (`int` | `None`, optional):
|
|
Number of messages to be retrieved. Due to limitations with
|
|
the API retrieving more than 3000 messages will take longer
|
|
than half a minute (or even more based on previous calls).
|
|
|
|
The limit may also be ``None``, which would eventually return
|
|
the whole history.
|
|
|
|
offset_date (`datetime`):
|
|
Offset date (messages *previous* to this date will be
|
|
retrieved). Exclusive.
|
|
|
|
offset_id (`int`):
|
|
Offset message ID (only messages *previous* to the given
|
|
ID will be retrieved). Exclusive.
|
|
|
|
max_id (`int`):
|
|
All the messages with a higher (newer) ID or equal to this will
|
|
be excluded.
|
|
|
|
min_id (`int`):
|
|
All the messages with a lower (older) ID or equal to this will
|
|
be excluded.
|
|
|
|
add_offset (`int`):
|
|
Additional message offset (all of the specified offsets +
|
|
this offset = older messages).
|
|
|
|
search (`str`):
|
|
The string to be used as a search query.
|
|
|
|
filter (:tl:`MessagesFilter` | `type`):
|
|
The filter to use when returning messages. For instance,
|
|
:tl:`InputMessagesFilterPhotos` would yield only messages
|
|
containing photos.
|
|
|
|
from_user (`entity`):
|
|
Only messages from this user will be returned.
|
|
This parameter will be ignored if it is not an user.
|
|
|
|
wait_time (`int`):
|
|
Wait time (in seconds) between different
|
|
:tl:`GetHistoryRequest`. Use this parameter to avoid hitting
|
|
the ``FloodWaitError`` as needed. If left to ``None``, it will
|
|
default to 1 second only if the limit is higher than 3000.
|
|
|
|
ids (`int`, `list`):
|
|
A single integer ID (or several IDs) for the message that
|
|
should be returned. This parameter takes precedence over
|
|
the rest (which will be ignored if this is set). This can
|
|
for instance be used to get the message with ID 123 from
|
|
a channel. Note that if the message doesn't exist, ``None``
|
|
will appear in its place, so that zipping the list of IDs
|
|
with the messages can match one-to-one.
|
|
|
|
.. note::
|
|
|
|
At the time of writing, Telegram will **not** return
|
|
:tl:`MessageEmpty` for :tl:`InputMessageReplyTo` IDs that
|
|
failed (i.e. the message is not replying to any, or is
|
|
replying to a deleted message). This means that it is
|
|
**not** possible to match messages one-by-one, so be
|
|
careful if you use non-integers in this parameter.
|
|
|
|
reverse (`bool`, optional):
|
|
If set to ``True``, the messages will be returned in reverse
|
|
order (from oldest to newest, instead of the default newest
|
|
to oldest). This also means that the meaning of `offset_id`
|
|
and `offset_date` parameters is reversed, although they will
|
|
still be exclusive. `min_id` becomes equivalent to `offset_id`
|
|
instead of being `max_id` as well since messages are returned
|
|
in ascending order.
|
|
|
|
You cannot use this if both `entity` and `ids` are ``None``.
|
|
|
|
Yields
|
|
Instances of `telethon.tl.custom.message.Message`.
|
|
|

|

|
|
|

|
|
Sends a message to the specified user, chat or channel.
|
|
|
|
The default parse mode is the same as the official applications
|
|
(a custom flavour of markdown). ``**bold**, `code` or __italic__``
|
|
are available. In addition you can send ``[links](https://example.com)``
|
|
and ``[mentions](@username)`` (or using IDs like in the Bot API:
|
|
``[mention](tg://user?id=123456789)``) and ``pre`` blocks with three
|
|
backticks.
|
|
|
|
Sending a ``/start`` command with a parameter (like ``?start=data``)
|
|
is also done through this method. Simply send ``'/start data'`` to
|
|
the bot.
|
|
|
|
See also `Message.respond() <telethon.tl.custom.message.Message.respond>`
|
|
and `Message.reply() <telethon.tl.custom.message.Message.reply>`.
|
|
|
|
Arguments
|
|
entity (`entity`):
|
|
To who will it be sent.
|
|
|
|
message (`str` | `Message <telethon.tl.custom.message.Message>`):
|
|
The message to be sent, or another message object to resend.
|
|
|
|
The maximum length for a message is 35,000 bytes or 4,096
|
|
characters. Longer messages will not be sliced automatically,
|
|
and you should slice them manually if the text to send is
|
|
longer than said length.
|
|
|
|
reply_to (`int` | `Message <telethon.tl.custom.message.Message>`, optional):
|
|
Whether to reply to a message or not. If an integer is provided,
|
|
it should be the ID of the message that it should reply to.
|
|
|
|
parse_mode (`object`, optional):
|
|
See the `TelegramClient.parse_mode
|
|
<telethon.client.messageparse.MessageParseMethods.parse_mode>`
|
|
property for allowed values. Markdown parsing will be used by
|
|
default.
|
|
|
|
link_preview (`bool`, optional):
|
|
Should the link preview be shown?
|
|
|
|
file (`file`, optional):
|
|
Sends a message with a file attached (e.g. a photo,
|
|
video, audio or document). The ``message`` may be empty.
|
|
|
|
force_document (`bool`, optional):
|
|
Whether to send the given file as a document or not.
|
|
|
|
clear_draft (`bool`, optional):
|
|
Whether the existing draft should be cleared or not.
|
|
Has no effect when sending a file.
|
|
|
|
buttons (`list`, `custom.Button <telethon.tl.custom.button.Button>`, :tl:`KeyboardButton`):
|
|
The matrix (list of lists), row list or button to be shown
|
|
after sending the message. This parameter will only work if
|
|
you have signed in as a bot. You can also pass your own
|
|
:tl:`ReplyMarkup` here.
|
|
|
|
All the following limits apply together:
|
|
|
|
* There can be 100 buttons at most (any more are ignored).
|
|
* There can be 8 buttons per row at most (more are ignored).
|
|
* The maximum callback data per button is 64 bytes.
|
|
* The maximum data that can be embedded in total is just
|
|
over 4KB, shared between inline callback data and text.
|
|
|
|
silent (`bool`, optional):
|
|
Whether the message should notify people in a broadcast
|
|
channel or not. Defaults to ``False``, which means it will
|
|
notify them. Set it to ``True`` to alter this behaviour.
|
|
|
|
Returns
|
|
The sent `custom.Message <telethon.tl.custom.message.Message>`.

Forwards the given messages to the specified entity.
|
|
|
|
If you want to "forward" a message without the forward header
|
|
(the "forwarded from" text), you should use `send_message` with
|
|
the original message instead. This will send a copy of it.
|
|
|
|
See also `Message.forward_to() <telethon.tl.custom.message.Message.forward_to>`.
|
|
|
|
Arguments
|
|
entity (`entity`):
|
|
To which entity the message(s) will be forwarded.
|
|
|
|
messages (`list` | `int` | `Message <telethon.tl.custom.message.Message>`):
|
|
The message(s) to forward, or their integer IDs.
|
|
|
|
from_peer (`entity`):
|
|
If the given messages are integer IDs and not instances
|
|
of the ``Message`` class, this *must* be specified in
|
|
order for the forward to work. This parameter indicates
|
|
the entity from which the messages should be forwarded.
|
|
|
|
silent (`bool`, optional):

Whether the message should notify people in a broadcast

channel or not. Defaults to ``False``, which means it will

notify them. Set it to ``True`` to alter this behaviour.
|
|
|
|
as_album (`bool`, optional):
|
|
Whether several image messages should be forwarded as an
|
|
album (grouped) or not. The default behaviour is to treat
|
|
albums specially and send outgoing requests with
|
|
``as_album=True`` only for the albums if message objects
|
|
are used. If IDs are used it will group by default.
|
|
|
|
In short, the default should do what you expect,
|
|
``True`` will group always (even converting separate
|
|
images into albums), and ``False`` will never group.
|
|
|
|
Returns
|
|
The list of forwarded `telethon.tl.custom.message.Message`,
|
|
or a single one if a list wasn't provided as input.
|
|
|
|
Note that if all messages are invalid (i.e. deleted) the call
|
|
will fail with ``MessageIdInvalidError``. If only some are
|
|
invalid, the list will have ``None`` instead of those messages.
