telegram.ext.RegexHandler

class telegram.ext.RegexHandler(pattern, callback, pass_groups=False, pass_groupdict=False, pass_update_queue=False, pass_job_queue=False, pass_user_data=False, pass_chat_data=False, allow_edited=False, message_updates=True, channel_post_updates=False, edited_updates=False, run_async=False)

Bases: telegram.ext.handler.Handler[telegram.update.Update, telegram.ext.utils.types.CCT]

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.

Note

This handler is being deprecated. For the same use case use: MessageHandler(Filters.regex(r'pattern'), callback)

Warning

When setting run_async to True, you cannot rely on adding custom attributes to telegram.ext.CallbackContext. See its docs for more info.

Parameters
  • pattern (str | Pattern) – The regex pattern.

  • callback (callable) –

    The callback function for this handler. Will be called when 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 telegram.ext.ConversationHandler.

  • pass_groups (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 (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 (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 telegram.ext.Updater and telegram.ext.Dispatcher that contains new updates which can be used to insert updates. Default is False.

  • pass_job_queue (bool, optional) – If set to True, a keyword argument called job_queue will be passed to the callback function. It will be a telegram.ext.JobQueue instance created by the telegram.ext.Updater which can be used to schedule new jobs. Default is False.

  • pass_user_data (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 (bool, optional) – If set to True, a keyword argument called chat_data will be passed to the callback function. Default is False.

  • message_updates (bool, optional) – Should “normal” message updates be handled? Default is True.

  • channel_post_updates (bool, optional) – Should channel posts updates be handled? Default is True.

  • edited_updates (bool, optional) – Should “edited” message updates be handled? Default is False.

  • run_async (bool) – Determines whether the callback will run asynchronously. Defaults to False.
