Authors:

- Brian Granger

## 3 Classes

class `IPython.html.notebookapp.``NotebookWebApplication`(ipython_app, kernel_manager, notebook_manager, cluster_manager, session_manager, log, base_url, settings_overrides, jinja_env_options)

  Bases: `tornado.web.Application`

  `__init__`(ipython_app, kernel_manager, notebook_manager, cluster_manager, session_manager, log, base_url, settings_overrides, jinja_env_options)

class `IPython.html.notebookapp.``NbserverListApp`(**kwargs)

  Bases: `IPython.core.application.BaseIPythonApplication`

class `IPython.html.notebookapp.``NotebookApp`(**kwargs)

  Bases: `IPython.core.application.BaseIPythonApplication`

  `cleanup_kernels`()

    Shutdown all kernels.

    The kernels will shutdown themselves when this process no longer exists, but explicit shutdown allows the KernelManagers to cleanup the connection files.

  `init_components`()

    Check the components submodule, and warn if it’s unclean

  `init_kernel_argv`()

    construct the kernel arguments

  `init_webapp`()

    initialize tornado webapp and httpserver

  `notebook_info`()

    Return the current working directory and the server url information

  `remove_server_info_file`()

    Remove the nbserver-<pid>.json file created for this server.

    Ignores the error raised when the file has already been removed.

  `server_info`()

    Return a JSONable dict of information about this server.

  `start`()

    Start the IPython Notebook server app, after initialization

    This method takes no arguments so all configuration and initialization must be done prior to calling this method.

  `static_file_path`

    return extra paths + the default location

  `write_server_info_file`()

    Write the result of server_info() to the JSON file info_file.

## 3 Functions

`IPython.html.notebookapp.``random_ports`(port, n)

  Generate a list of n random ports near the given port.

  The first 5 ports will be sequential, and the remaining n-5 will be randomly selected in the range [port-2*n, port+2*n].

`IPython.html.notebookapp.``load_handlers`(name)

  Load the (URL pattern, handler) tuples for each component.

`IPython.html.notebookapp.``list_running_servers`(profile='default')

  Iterate over the server info files of running notebook servers.

  Given a profile name, find nbserver-* files in the security directory of that profile, and yield dicts of their information, each one pertaining to a currently running notebook server instance.
