Initial project setup including the main agent script, configuration files, profile JSON state, systemd service unit, startup script, deployment documentation, and Python dependencies. Includes .env, venv/, and __pycache__/ which should likely be excluded via .gitignore to avoid committing secrets and artifacts.

``/``. The handler will add a :obj:`list` to the
|
|
:class:`CallbackContext` named :attr:`CallbackContext.args`. It will contain a list of strings,
|
|
which is the text following the command split on single whitespace characters.
|

|
Note:
|
|
This handler is not used to handle Telegram :class:`telegram.Update`, but strings manually
|
|
put in the queue. For example to send messages with the bot using command line or API.

|
|
Warning:
|
|
When setting :paramref:`block` to :obj:`False`, you cannot rely on adding custom
|
|
attributes to :class:`telegram.ext.CallbackContext`. See its docs for more info.
|
|
|
|
Args:
|
|
command (:obj:`str`): The command this handler should listen for.
|
|
callback (:term:`coroutine function`): The callback function for this handler. Will be
|
|
called when :meth:`check_update` has determined that an update should be processed by
|
|
this handler. Callback signature::
|
|
|
|
async 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`.
|
|
block (:obj:`bool`, optional): Determines whether the return value of the callback should
|
|
be awaited before processing the next handler in
|
|
:meth:`telegram.ext.Application.process_update`. Defaults to :obj:`True`.
