Grader produces files that contain the reference code and learner template with .m extension. Grader can be used in Python scripts, the Python and IPython shell.

Main Features

Here are the things that grader does well:

• Easy matlab grader code scraping(reference code, learner code, ...)

Upcoming Features

• Email notifications about students submissions and statistics

Where to get it

The source code is currently hosted on GitHub at: https://github.com/sarmientoF/grader.git

# PyPI
pip3 install git+https://github.com/sarmientoF/grader.git

How to use it

• You must login at least once with the following command, this will crate a file called .credentials.json(🚨 Do not edit this file, it is generated automatically)

import grader
grader.login(YOUR_EMAIL, YOUR_PASSWORD)

• Load your credentials everytime you use any other feature but login

import grader

if __name__ == "__main__":
    grader.loadCredentials()
    # ... other lines of code

• The following lines of code load your credential and generate the follwing file myGrader.json(this contains the structure of your grader courses, such as: Courses, Assignments, Problems ...)

import grader

if __name__ == "__main__":
    grader.loadCredentials()
    grader.getGraderJson()

• The following lines of code will create a folder called codes(this contains all the problems contained in your grader courses) and .html(this contains html pages of each grader problem)

import grader

if __name__ == "__main__": ## THIS IS MAIN THREAD
    grader.loadCredentials()
    grader.saveProblems() ## MUST BE INSIDE MAIN THREAD
