#
#  The values will be stored in the database. Please see the API documentation on

#  is another configurable variable.
#  Default: ''
# c.CourseDirectory.db_url = ''

## Format string for the directory structure that nbgrader works over during the
#  grading process. This MUST contain named keys for 'nbgrader_step',

## Make all instructor files group writeable (g+ws, default g+r only) and
#  exchange directories group readable/writeable (g+rws, default g=nothing only )
#  by default.  This should only be used if you carefully set the primary groups
#  of your notebook servers and fully understand the unix permission model.  This
#  changes the default permissions from 444 (unwriteable) to 664 (writeable), so
#  that other instructors are able to delete/overwrite files.
#  Default: False
# c.CourseDirectory.groupshared = False

## List of file names or file globs. Upon copying directories recursively,
#  matching files and directories will be ignored with a debug message.
#  Default: ['.ipynb_checkpoints', '*.pyc', '__pycache__', 'feedback']
# c.CourseDirectory.ignore = ['.ipynb_checkpoints', '*.pyc', '__pycache__', 'feedback']

## List of file names or file globs. Upon copying directories recursively, non
#  matching files will be ignored with a debug message.
#  Default: ['*']
# c.CourseDirectory.include = ['*']

## Maximum size of files (in kilobytes; default: 100Mb). Upon copying directories

#  Default: 100000
# c.CourseDirectory.max_file_size = 100000

## File glob to match notebook names, excluding the '.ipynb' extension. This can
#  be changed to filter by notebook.
#  Default: '*'
# c.CourseDirectory.notebook_id = '*'

## The name of the directory that contains the version of the assignment that
#  will be released to students. This corresponds to the `nbgrader_step` variable
#  in the `directory_structure` config option.
#  Default: 'release'
# c.CourseDirectory.release_directory = 'release'

## The root directory for the course files (that includes the `source`,

#  current working directory.
#  Default: ''
# c.CourseDirectory.root = ''

## The name of the directory that contains the master/instructor version of
#  assignments. This corresponds to the `nbgrader_step` variable in the
#  `directory_structure` config option.
#  Default: 'source'
# c.CourseDirectory.source_directory = 'source'

## File glob to match student IDs. This can be changed to filter by student.
#  Note: this is always changed to '.' when running `nbgrader assign`, as the
#  assign step doesn't have any student ID associated with it. With `nbgrader
#  submit`, this instead forces the use of an alternative student ID for the
#  submission. See `nbgrader submit --help`.
#
#  If the ID is purely numeric and you are passing it as a flag on the command
#  line, you will need to escape the quotes in order to have it detected as a
#  string, for example `--student=""12345""`. See:
#
#      https://github.com/jupyter/nbgrader/issues/743
#
#  for more details.
#  Default: '*'
# c.CourseDirectory.student_id = '*'

## Comma-separated list of student IDs to exclude.  Counterpart of student_id.
#
#  This is useful when running commands on all students, but certain students
#  cause errors or otherwise must be left out.  Works at least for autograde,
#  generate_feedback, and release_feedback.
#  Default: ''
# c.CourseDirectory.student_id_exclude = ''

## The name of the directory that contains assignments that have been submitted
#  by students for grading. This corresponds to the `nbgrader_step` variable in
#  the `directory_structure` config option.

# NotebookClient(LoggingConfigurable) configuration
# ------------------------------------------------------------------------------
## Encompasses a Client for executing cells in a notebook

## List of error names which won't stop the execution. Use this if the
#  ``allow_errors`` option it too general and you want to allow only specific
#  kinds of errors.
#  Default: []
# c.NotebookClient.allow_error_names = []

## If ``False`` (default), when a cell raises an error the execution is stopped
#  and a ``CellExecutionError`` is raised, except if the error name is in
#  ``allow_error_names``. If ``True``, execution errors are ignored and the
#  execution is continued until the end of the notebook. Output from exceptions
#  is included in the cell output in both cases.
#  Default: False
# c.NotebookClient.allow_errors = False

## An ordered list of preferred output type, the first encountered will usually
#  be used when converting discarding the others.
#  Default: ['text/html', 'application/pdf', 'text/latex', 'image/svg+xml', 'image/png', 'image/jpeg', 'text/markdown', 'text/plain']
# c.NotebookClient.display_data_priority = ['text/html', 'application/pdf', 'text/latex', 'image/svg+xml', 'image/png', 'image/jpeg', 'text/markdown', 'text/plain']

## If a cell execution was interrupted after a timeout, don't wait for the
#  execute_reply from the kernel (e.g. KeyboardInterrupt error). Instead, return
#  an execute_reply with the given error, which should be of the following form::
#
#      {
#          'ename': str,  # Exception name, as a string
#          'evalue': str,  # Exception value, as a string

#      }
#  Default: None
# c.NotebookClient.error_on_timeout = None

#  Default: []
# c.NotebookClient.extra_arguments = []

## If False (default), errors from executing the notebook can be allowed with a
#  ``raises-exception`` tag on a single cell, or the ``allow_errors`` or
#  ``allow_error_names`` configurable options for all cells. An allowed error
#  will be recorded in notebook output, and execution will continue. If an error
#  occurs when it is not explicitly allowed, a ``CellExecutionError`` will be
#  raised. If True, ``CellExecutionError`` will be raised for any error that
#  occurs while executing the notebook. This overrides the ``allow_errors`` and
#  ``allow_error_names`` options and the ``raises-exception`` cell tag.
#  Default: False
# c.NotebookClient.force_raise_errors = False

## If execution of a cell times out, interrupt the kernel and continue executing
#  other cells rather than throwing an error and stopping.
#  Default: False
# c.NotebookClient.interrupt_on_timeout = False

## The time to wait (in seconds) for IOPub output. This generally doesn't need to
#  be set, but on some slow networks (such as CI systems) the default timeout
#  might not be long enough to get all messages.
#  Default: 4
# c.NotebookClient.iopub_timeout = 4

## Path to file to use for SQLite history database for an IPython kernel.
#
#          The specific value ``:memory:`` (including the colon
#          at both end but not the back ticks), avoids creating a history file. Otherwise, IPython
#          will create a history file for each kernel.
#
#          When running kernels simultaneously (e.g. via multiprocessing) saving history a single
#          SQLite file can result in database errors, so using ``:memory:`` is recommended in
#          non-interactive contexts.
#  Default: ':memory:'
# c.NotebookClient.ipython_hist_file = ':memory:'

## The kernel manager class to use.
#  Default: 'builtins.object'

# c.NotebookClient.on_cell_complete = None

## A callable which executes when a cell execution results in an error. This is
#  executed even if errors are suppressed with ``cell_allows_errors``. Called
#  with kwargs ``cell`, ``cell_index`` and ``execute_reply``.
#  Default: None
# c.NotebookClient.on_cell_error = None

## A callable which executes just before a code cell is executed. Called with
#  kwargs ``cell`` and ``cell_index``.
#  Default: None
# c.NotebookClient.on_cell_execute = None

## A callable which executes just after a code cell is executed, whether or not

## A callable which executes before a cell is executed and before non-executing
#  cells are skipped. Called with kwargs ``cell`` and ``cell_index``.
#  Default: None
# c.NotebookClient.on_cell_start = None

## A callable which executes after the kernel is cleaned up. Called with kwargs
#  ``notebook``.
#  Default: None
# c.NotebookClient.on_notebook_complete = None

## A callable which executes when the notebook encounters an error. Called with
#  kwargs ``notebook``.
#  Default: None

#  setup, and cells are about to execute. Called with kwargs ``notebook``.
#  Default: None

## If ``False`` (default), then the kernel will continue waiting for iopub
#  messages until it receives a kernel idle message, or until a timeout occurs,
#  at which point the currently executing cell will be skipped. If ``True``, then
#  an error will be raised after the first timeout. This option generally does
#  not need to be used, but may be useful in contexts where there is the
#  possibility of executing notebooks with memory-consuming infinite loops.

#  Default: None
# c.NotebookClient.timeout = None

## A callable which, when given the cell source as input, returns the time to
#  wait (in seconds) for output from cell executions. If a cell execution takes
#  longer, a TimeoutError is raised.
#
#  Returning ``None`` or ``-1`` will disable the timeout for the cell. Not
#  setting ``timeout_func`` will cause the client to default to using the
#  ``timeout`` trait for all cells. The ``timeout_func`` trait overrides
#  ``timeout`` if it is not ``None``.
