"""Handler class to handle string updates based on a regex which checks the update content.
Read the documentation of the ``re`` module for more information. The ``re.match`` function is
used to determine if an update should be handled by this handler.
2016-04-16 16:36:12 +02:00
Note:
This handler is not used to handle Telegram :attr:`telegram.Update`, but strings manually
put in the queue. For example to send messages with the bot using command line or API.
2020-10-04 17:20:33 +02:00
Warning:
When setting ``run_async`` to :obj:`True`, you cannot rely on adding custom
attributes to :class:`telegram.ext.CallbackContext`. See its docs for more info.
2016-04-16 16:36:12 +02:00
Args:
pattern (:obj:`str` | :obj:`Pattern`): The regex pattern.
callback (:obj:`callable`): The callback function for this handler. Will be called when
:attr:`check_update` has determined that an update should be processed by this handler.
Callback signature for context based API:
``def callback(update: Update, context: CallbackContext)``
The return value of the callback is usually ignored except for the special case of
:class:`telegram.ext.ConversationHandler`.
pass_groups (:obj:`bool`, optional): If the callback should be passed the result of
``re.match(pattern, data).groups()`` as a keyword argument called ``groups``.
