# Configuration file for lab.

#------------------------------------------------------------------------------
# Application(SingletonConfigurable) configuration
#------------------------------------------------------------------------------
## This is an application.

## The date format used by logging formatters for %(asctime)s
#  Default: '%Y-%m-%d %H:%M:%S'
# c.Application.log_datefmt = '%Y-%m-%d %H:%M:%S'

## The Logging format template
#  Default: '[%(name)s]%(highlevel)s %(message)s'
# c.Application.log_format = '[%(name)s]%(highlevel)s %(message)s'

## Set the log level by value or name.
#  Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
#  Default: 30
# c.Application.log_level = 30

## Configure additional log handlers.
#  
#  The default stderr logs handler is configured by the log_level, log_datefmt
#  and log_format settings.
#  
#  This configuration can be used to configure additional handlers (e.g. to
#  output the log to a file) or for finer control over the default handlers.
#  
#  If provided this should be a logging configuration dictionary, for more
#  information see:
#  https://docs.python.org/3/library/logging.config.html#logging-config-
#  dictschema
#  
#  This dictionary is merged with the base logging configuration which defines
#  the following:
#  
#  * A logging formatter intended for interactive use called
#    ``console``.
#  * A logging handler that writes to stderr called
#    ``console`` which uses the formatter ``console``.
#  * A logger with the name of this application set to ``DEBUG``
#    level.
#  
#  This example adds a new handler that writes to a file:
#  
#  .. code-block:: python
#  
#     c.Application.logging_configuration = {

# ExtensionApp(JupyterApp) configuration
#------------------------------------------------------------------------------
## Base class for configurable Jupyter Server Extension Applications.
#  
#      ExtensionApp subclasses can be initialized two ways:
#      1. Extension is listed as a jpserver_extension, and ServerApp calls
#          its load_jupyter_server_extension classmethod. This is the
#          classic way of loading a server extension.
#      2. Extension is launched directly by calling its `launch_instance`
#          class method. This method can be set as a entry_point in
#          the extensions setup.py

## Override URL shown to users.
#  
#          Replace actual URL, including protocol, address, port and base URL,
#          with the given value when displaying URL to the users. Do not change
#          the actual connection URL. If authentication token is enabled, the
#          token is added to the custom URL automatically.
#  
#          This option is intended to be used when the URL to display to the user
#          cannot be determined reliably by the Jupyter server (proxified
#          or containerized setups for example).
#  Default: ''
# c.ServerApp.custom_display_url = ''

## The default URL to redirect to from `/`
#  Default: '/'
# c.ServerApp.default_url = '/'

## Disable cross-site-request-forgery protection
#  
#          Jupyter notebook 4.3.1 introduces protection from cross-site request forgeries,
#          requiring API requests to either:
#  
#          - originate from pages served by this server (validated with XSRF cookie and token), or
#          - authenticate with a token
#  
#          Some anonymous compute resources still desire the ability to run code,
#          completely without authentication.
#          These services can disable all authentication and security checks,
#          with the full knowledge of what that implies.
#  Default: False
# c.ServerApp.disable_check_xsrf = False

## handlers that should be loaded at higher priority than the default services
#  Default: []
# c.ServerApp.extra_services = []

## Extra paths to search for serving static files.

# c.ServerApp.kernel_manager_class = 'jupyter_server.services.kernels.kernelmanager.AsyncMappingKernelManager'

## The kernel spec manager class to use. Should be a subclass of

#  between this version of Jupyter and the next stable one.
#  Default: 'jupyter_client.kernelspec.KernelSpecManager'
# c.ServerApp.kernel_spec_manager_class = 'jupyter_client.kernelspec.KernelSpecManager'

## Preferred kernel message protocol over websocket to use (default: None). If an
#  empty string is passed, select the legacy protocol. If None, the selected
#  protocol will depend on what the front-end supports (usually the most recent
#  protocol supported by the back-end and the front-end).
#  Default: None
# c.ServerApp.kernel_ws_protocol = None

## The full path to a private key file for usage with SSL/TLS.
#  Default: ''
# c.ServerApp.keyfile = ''

#  the rate.
#  Default: True
# c.ServerApp.limit_rate = True

## Hostnames to allow as local when allow_remote_access is False.
#  
#         Local IP addresses (such as 127.0.0.1 and ::1) are automatically accepted
#         as local as well.
#  Default: ['localhost']

# c.ServerApp.min_open_files_limit = 0

## DEPRECATED, use root_dir.
#  Default: ''
# c.ServerApp.notebook_dir = ''

## Whether to open in a browser after starting.
#                          The specific browser used is platform dependent and
#                          determined by the python standard library `webbrowser`
#                          module, unless it is overridden using the --browser
#                          (ServerApp.browser) configuration option.
#  Default: False
# c.ServerApp.open_browser = False

## Hashed password to use for web authentication.
#  
#                        To generate, type in a python/IPython shell:
#  
#                          from jupyter_server.auth import passwd; passwd()
#  
#                        The string should be of the form type:salt:hashed-
#  password.
#  Default: ''
# c.ServerApp.password = ''

## Forces users to use a password for the Jupyter server.
#                        This is useful in a multi user environment, for instance when
#                        everybody in the LAN can access each other's machine through ssh.
#  
#                        In such a case, serving on localhost is not secure since
#                        any user can connect to the Jupyter server via ssh.
#  Default: False
# c.ServerApp.password_required = False

## The port the server will listen on (env: JUPYTER_PORT).
#  Default: 0
# c.ServerApp.port = 0

## The number of additional ports to try if the specified port is not available
#  (env: JUPYTER_PORT_RETRIES).
#  Default: 50
# c.ServerApp.port_retries = 50

## Preferred starting directory to use for notebooks and kernels.
#  Default: ''
#c.ServerApp.preferred_dir = '/'

## DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
#  Default: 'disabled'
# c.ServerApp.pylab = 'disabled'

## If True, display controls to shut down the Jupyter server, such as menu items
#  or buttons.
#  Default: True
# c.ServerApp.quit_button = True

## (sec) Time window used to
#          check the message and data rate limits.
#  Default: 3
# c.ServerApp.rate_limit_window = 3

## Reraise exceptions encountered loading server extensions?
#  Default: False
# c.ServerApp.reraise_server_extension_failures = False

## The directory to use for notebooks and kernels.
#  Default: ''
# c.ServerApp.root_dir = ''

## The session manager class to use.
#  Default: 'jupyter_server.services.sessions.sessionmanager.SessionManager'
# c.ServerApp.session_manager_class = 'jupyter_server.services.sessions.sessionmanager.SessionManager'

## Instead of starting the Application, dump configuration to stdout
#  See also: Application.show_config
# c.ServerApp.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  See also: Application.show_config_json
# c.ServerApp.show_config_json = False

## Shut down the server after N seconds with no kernels or terminals running and
#  no activity. This can be used together with culling idle kernels
#  (MappingKernelManager.cull_idle_timeout) to shutdown the Jupyter server when
#  it's not in use. This is not precisely timed: it may shut down up to a minute
#  later. 0 (the default) disables this automatic shutdown.
#  Default: 0
# c.ServerApp.shutdown_no_activity_timeout = 0

## The UNIX socket the Jupyter server will listen on.
#  Default: ''
# c.ServerApp.sock = ''

## The permissions mode for UNIX socket creation (default: 0600).
#  Default: '0600'
# c.ServerApp.sock_mode = '0600'

## Supply SSL options for the tornado HTTPServer.
#              See the tornado docs for details.
#  Default: {}
# c.ServerApp.ssl_options = {}

## Supply overrides for terminado. Currently only supports "shell_command".
#  Default: {}
# c.ServerApp.terminado_settings = {}

## Set to False to disable terminals.
#  
#           This does *not* make the server more secure by itself.
#           Anything the user can in a terminal, they can also do in a notebook.
#  
#           Terminals may also be automatically disabled if the terminado package
#           is not available.
#  Default: True
# c.ServerApp.terminals_enabled = True

## Token used for authenticating first-time connections to the server.
#  
#          The token can be read from the file referenced by JUPYTER_TOKEN_FILE or set directly
#          with the JUPYTER_TOKEN environment variable.
#  
#          When no password is enabled,
#          the default is to generate a new, random token.
#  
#          Setting to an empty string disables authentication altogether, which
#  is NOT RECOMMENDED.
#  Default: '<generated>'
# c.ServerApp.token = '<generated>'

## Supply overrides for the tornado.web.Application that the Jupyter server uses.
#  Default: {}
# c.ServerApp.tornado_settings = {}

## Whether to trust or not X-Scheme/X-Forwarded-Proto and X-Real-Ip/X-Forwarded-
#  For headerssent by the upstream reverse proxy. Necessary if the proxy handles
#  SSL
#  Default: False
# c.ServerApp.trust_xheaders = False

## Disable launching browser by redirect file
#       For versions of notebook > 5.7.2, a security feature measure was added that
#       prevented the authentication token used to launch the browser from being visible.
#       This feature makes it difficult for other users on a multi-user system from
#       running code in your Jupyter session as you.
#       However, some environments (like Windows Subsystem for Linux (WSL) and Chromebooks),
#       launching a browser using a redirect file can lead the browser failing to load.
#       This is because of the difference in file structures/paths between the runtime and
#       the browser.
#  
#       Disabling this setting to False will disable this behavior, allowing the browser
#       to launch by using a URL and visible token (as before).
#  Default: True
# c.ServerApp.use_redirect_file = True

## Specify where to open the server on startup. This is the
#          `new` argument passed to the standard library method `webbrowser.open`.
#          The behaviour is not guaranteed, but depends on browser support. Valid
#          values are:
#  
#           - 2 opens a new tab,
#           - 1 opens a new window,
#           - 0 opens in an existing window.
#  
#          See the `webbrowser.open` documentation for details.
#  Default: 2
# c.ServerApp.webbrowser_open_new = 2

## Set the tornado compression options for websocket connections.
#  
#  This value will be returned from
#  :meth:`WebSocketHandler.get_compression_options`. None (default) will disable
#  compression. A dict (even an empty one) will enable compression.
#  
#  See the tornado docs for WebSocketHandler.get_compression_options for details.
#  Default: None
# c.ServerApp.websocket_compression_options = None

## The base URL for websockets,
#          if it differs from the HTTP server (hint: it almost certainly doesn't).
#  
#          Should be in the form of an HTTP origin: ws[s]://hostname[:port]
#  Default: ''
# c.ServerApp.websocket_url = ''
