class RegexHandler(MessageHandler):
|
|
"""Handler class to handle Telegram updates based on a regex.
|
|
|
|
It uses a regular expression to check text messages. 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.
|
|
|
|
Attributes:
|
|
pattern (:obj:`str` | :obj:`Pattern`): The regex pattern.
|
|
callback (:obj:`callable`): The callback function for this handler.
|
|
pass_groups (:obj:`bool`): Determines whether ``groups`` will be passed to the
|
|
callback function.
|
|
pass_groupdict (:obj:`bool`): Determines whether ``groupdict``. will be passed to
|
|
the callback function.
|
|
pass_update_queue (:obj:`bool`): Determines whether ``update_queue`` will be
|
|
passed to the callback function.
|
|
pass_job_queue (:obj:`bool`): Determines whether ``job_queue`` will be passed to
|
|
the callback function.
|
|
pass_user_data (:obj:`bool`): Determines whether ``user_data`` will be passed to
|
|
the callback function.
|
|
pass_chat_data (:obj:`bool`): Determines whether ``chat_data`` will be passed to
|
|
the callback function.
|
|
|
|
Note:
|
|
This handler is being deprecated. For the same usecase use:
|
|
``MessageHandler(Filters.regex(r'pattern'), callback)``
|
|
|
|
|
|
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``.
|
|
Default is ``False``
|
|
pass_groupdict (:obj:`bool`, optional): If the callback should be passed the result of
|
|
``re.match(pattern, data).groupdict()`` as a keyword argument called ``groupdict``.
|
|
Default is ``False``
|
|
pass_update_queue (:obj:`bool`, optional): 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 :class:`telegram.ext.Updater` and :class:`telegram.ext.Dispatcher`
|
|
that contains new updates which can be used to insert updates. Default is ``False``.
|
|
pass_job_queue (:obj:`bool`, optional): If set to ``True``, a keyword argument called
|
|
``job_queue`` will be passed to the callback function. It will be a
|
|
:class:`telegram.ext.JobQueue` instance created by the :class:`telegram.ext.Updater`
|
|
which can be used to schedule new jobs. Default is ``False``.
|
|
pass_user_data (:obj:`bool`, optional): If set to ``True``, a keyword argument called
|
|
``user_data`` will be passed to the callback function. Default is ``False``.
|
|
pass_chat_data (:obj:`bool`, optional): If set to ``True``, a keyword argument called
|
|
``chat_data`` will be passed to the callback function. Default is ``False``.
|
|
message_updates (:obj:`bool`, optional): Should "normal" message updates be handled?
|
|
Default is ``True``.
|
|
channel_post_updates (:obj:`bool`, optional): Should channel posts updates be handled?
|
|
Default is ``True``.
|
|
edited_updates (:obj:`bool`, optional): Should "edited" message updates be handled? Default
|
|
is ``False``.
