Iterator over the message history for the specified entity.

:tl:`messages.Search` will be used instead of :tl:`messages.getHistory`.
|
|
|
|
Args:
|
|
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`.
|
|
|
|
Notes:
|
|
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).
