"""
|
|
Occurs whenever a message is edited. Just like `NewMessage
|
|
<telethon.events.newmessage.NewMessage>`, you should treat
|
|
this event as a `Message <telethon.tl.custom.message.Message>`.
|
|
|
|
.. warning::
|
|
|
|
On channels, `Message.out <telethon.tl.custom.message.Message>`
|
|
will be `True` if you sent the message originally, **not if
|
|
you edited it**! This can be dangerous if you run outgoing
|
|
commands on edits.
|
|
|
|
Some examples follow:
|
|
|
|
* You send a message "A", ``out is True``.
|
|
* You edit "A" to "B", ``out is True``.
|
|
* Someone else edits "B" to "C", ``out is True`` (**be careful!**).
|
|
* Someone sends "X", ``out is False``.
|
|
* Someone edits "X" to "Y", ``out is False``.
|
|
* You edit "Y" to "Z", ``out is False``.
|
|
|
|
Since there are useful cases where you need the right ``out``
|
|
value, the library cannot do anything automatically to help you.
|
|
Instead, consider using ``from_users='me'`` (it won't work in
|
|
broadcast channels at all since the sender is the channel and
|
|
not you).
