nbgrader fetch assignmentΒΆ

Fetch an assignment from the nbgrader exchange

Options
=======
The options below are convenience aliases to configurable class-options,
as listed in the "Equivalent to" description-line of the aliases.
To see all configurable class-options for some <cmd>, use:
    <cmd> --help-all

--debug
    set log level to DEBUG (maximize logging output)
    Equivalent to: [--Application.log_level=DEBUG]
--quiet
    set log level to CRITICAL (minimize logging output)
    Equivalent to: [--Application.log_level=CRITICAL]
--replace
    replace missing files, even if the assignment has already been fetched
    Equivalent to: [--ExchangeFetchAssignment.replace_missing_files=True]
--log-level=<Enum>
    Set the log level by value or name.
    Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
    Default: 30
    Equivalent to: [--Application.log_level]
--student=<Unicode>
    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: '*'
    Equivalent to: [--CourseDirectory.student_id]
--assignment=<Unicode>
    The assignment name. This MUST be specified, either by setting the config
    option, passing an argument on the command line, or using the --assignment
    option on the command line.
    Default: ''
    Equivalent to: [--CourseDirectory.assignment_id]
--notebook=<Unicode>
    File glob to match notebook names, excluding the '.ipynb' extension. This
    can be changed to filter by notebook.
    Default: '*'
    Equivalent to: [--CourseDirectory.notebook_id]
--db=<Unicode>
    URL to the database. Defaults to sqlite:///<root>/gradebook.db, where <root>
    is another configurable variable.
    Default: ''
    Equivalent to: [--CourseDirectory.db_url]
--course-dir=<Unicode>
    The root directory for the course files (that includes the `source`,
    `release`, `submitted`, `autograded`, etc. directories). Defaults to the
    current working directory.
    Default: ''
    Equivalent to: [--CourseDirectory.root]
--timezone=<Unicode>
    Timezone for recording timestamps
    Default: 'UTC'
    Equivalent to: [--Exchange.timezone]
--course=<Unicode>
    A key that is unique per instructor and course. This can be specified,
    either by setting the config option, or using the --course option on the
    command line.
    Default: ''
    Equivalent to: [--CourseDirectory.course_id]

Class options
=============
The command-line option below sets the respective configurable class-parameter:
    --Class.parameter=value
This line is evaluated in Python, so simple expressions are allowed.
For instance, to set `C.a=[0,1,2]`, you may type this:
    --C.a='range(3)'

    will be released to students. This corresponds to the `nbgrader_step`
    variable in the `directory_structure` config option.
    Default: 'release'
--CourseDirectory.root=<Unicode>
    The root directory for the course files (that includes the `source`,

    The name of the directory that contains the assignment solution after
    grading has been completed. This corresponds to the `nbgrader_step` variable
    in the `directory_structure` config option.
    Default: 'solution'
--CourseDirectory.source_directory=<Unicode>
    The name of the directory that contains the master/instructor version of

--CourseDirectory.student_id=<Unicode>
    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:

    for more details.
    Default: '*'
--CourseDirectory.student_id_exclude=<Unicode>
    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: ''
--CourseDirectory.submitted_directory=<Unicode>
    The name of the directory that contains assignments that have been submitted
    by students for grading. This corresponds to the `nbgrader_step` variable in

Examples
--------

    Fetch an assignment that an instructor has released. For the usage of students.

            You can run this command from any directory, but usually, you will have a
            directory where you are keeping your course assignments.

            To fetch an assignment by name into the current directory:

                nbgrader fetch_assignment assignment1

            To fetch an assignment for a specific course, you must first know the
            `course_id` for your course.  If you don't know it, ask your instructor.
            Then, simply include the argument with the '--course' flag.

                nbgrader fetch_assignment assignment1 --course=phys101

            This will create an new directory named `assignment1` where you can work
            on the assignment. When you are done, use the `nbgrader submit` command
            to turn in the assignment.
