A MOSS written in Python. The code uses API from moss.py. It is a command line tool, you have to give it a bunch of parameters, as it is noted in the Usage.

You need to register with MOSS to obtain a userid. Instructions here

It accepts .zip file of the assignments, e.g, Canvas Exported file. And it can also work for source file like .java.

Command line requirements

• --infile : followed by the name of the .zip file. You can repeat this argument multiple times to include multiple .zip files.
• -- outfolder : followed by the name of the root folder you want to place the extracted files; it will create this folder
• --userid : Your MOSS assigned userid
• --language : Followed by the programming language, e.g, Python, Java
• --file_ext: source file extension, e.g, py, java

If you need baseline file, create a folder named base at the folder of checker.py, put the baseline files into it manually.

If you have one .zip file, an example command line looks like…

python checker.py --infile submissions.zip --outfolder hw --userid 12345 --language Java

If you have two .zip file, an example command line looks like…

python checker.py --infile submissions.zip --infile submissions2.zip --outfolder hw --userid 12345 --language Java

The program unzip all the assignments, extract each student’s source file into their own folder and then submits them all to MOSS (all file would be removed other than the source file). When it is complete, it writes a ‘report.html’ file you can open to view the results. Refer to the Reading the Results for how to interpret the results.
