Not strictly needed, but it helps show that the project is being actively developed which I find important.

|
|
Handler class to handle Telegram callback queries. Optionally based on a regex.
|
|
Read the documentation of the ``re`` module for more information.
|
|
|
|
Args:
|
|
callback (function): A function that takes ``bot, update`` as
|
|
positional arguments. It will be called when the ``check_update``
|
|
has determined that an update should be processed by this handler.
|
|
pass_update_queue (optional[bool]): If set to ``True``, a keyword argument called
|
|
``update_queue`` will be passed to the callback function. It will be the ``Queue``
|
|
instance used by the ``Updater`` and ``Dispatcher`` that contains new updates which can
|
|
be used to insert updates. Default is ``False``.
|
|
pass_job_queue (optional[bool]): If set to ``True``, a keyword argument called
|
|
``job_queue`` will be passed to the callback function. It will be a ``JobQueue``
|
|
instance created by the ``Updater`` which can be used to schedule new jobs.
|
|
Default is ``False``.
|
|
pattern (optional[str or Pattern]): Optional regex pattern. If not ``None`` ``re.match``
|
|
is used to determine if an update should be handled by this handler.
|
|
pass_groups (optional[bool]): If the callback should be passed the
|
|
result of ``re.match(pattern, data).groups()`` as a keyword
|
|
argument called ``groups``. Default is ``False``
|
|
pass_groupdict (optional[bool]): If the callback should be passed the
|
|
result of ``re.match(pattern, data).groupdict()`` as a keyword
|
|
argument called ``groupdict``. Default is ``False``
|
|
pass_user_data (optional[bool]): If set to ``True``, a keyword argument called
|
|
``user_data`` will be passed to the callback function. It will be a ``dict`` you
|
|
can use to keep any data related to the user that sent the update. For each update of
|
|
the same user, it will be the same ``dict``. Default is ``False``.
|
|
pass_chat_data (optional[bool]): If set to ``True``, a keyword argument called
|
|
``chat_data`` will be passed to the callback function. It will be a ``dict`` you
|
|
can use to keep any data related to the chat that the update was sent in.
|
|
For each update in the same chat, it will be the same ``dict``. Default is ``False``.
