Requirements

To handle zipped submissions, a respective unpacking tool must be present on the host system.

• 7z: Most Linux distros provide a p7zip package.
• rar: Provide for the unrar executable.

Using pip

pip3 install --user coloredlogs patool

Using a virtual environment with pipenv

pipenv install installs the requirements defined in Pipfile,
pipenv shell spawns a shell process to work in the virtual environment.

Usage

usage: autograde.py [-h] -a ASSIGNMENT [--dangerous] [-i] [-f] [-n] [-o OUTPUT] inputfiles [inputfiles ...]

positional arguments:
  inputfiles

optional arguments:
  -h, --help            show this help message and exit
  -a ASSIGNMENT, --assignment ASSIGNMENT
                        Name of the assignment
  --dangerous           Ignore validation warnings
  -i, --interactive     Pass --interactive to halt on validation errors
  -f, --force           Pass --force to nbgrader autograde
  -n, --noop            Do not run autograde and feedback
  -o OUTPUT, --output OUTPUT
                        Output directory for html feedback

For example, when running
./autograde.py -a assignment-2 Submissions.zip

the following steps will be executed:

1. retrieve the correct notebook filename from ./source/assignment-2/
2. collect student or group submissions from Submissions.zip:
   • unpack (nested) zipped submissions
   • valid submissions go into ./submitted/(student|group)/assignment-2/
   • submissions excluded by a validator go into ./dangerous/ instead
3. autograde each valid submission if it was not already autograded
4. list a summary of errors and problems encountered so far
5. wait and ask you to optionally perform additional formgrading using your browser
6. generate feedback for each submission and collect all .html files into upload/assignment-2/
