Handler class to handle string commands. Commands are string updates
|
|
that start with ``/``.
|
|
|
|
Args:
|
|
command (str): The name of the command this handler should listen for.
|
|
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_args (optional[bool]): If the handler should be passed the
|
|
arguments passed to the command as a keyword argument called `
|
|
``args``. It will contain a list of strings, which is the text
|
|
following the command split on single or consecutive whitespace characters.
|
|
Default is ``False``
|
|
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``.
