codediff

A file differencer for use in APCS(P) classes. The unix-based diff is useful for comparing files, but is not intended to use the differences for statistical analysis. codediff is intended primary to catch cheating. 💻

Installing

To install codediff, clone the git repo using git clone https://github.com/dmontgrmry/codediff.git.

Linux and Mac

codediff is written in Python 3. If Python 3 is not installed or has a version less than version 3.4.0, download and install it here. There are future plans to enable Python 2 compatability. Alternatively, run ./install after cloning the repository. The installation script will download and build Python 3 from source.

Windows

Currently, there is no installation script for Windows. If Python 3 is not installed or has a version less than version 3.4.0, download and install it here.

Great! Let's move on. 👍

Usage

Instead of running codediff via python3 codediff.py, run the executable ./codediff. To compare files and/or directories, simply append them to the end of the executable in the console. For example, running ./codediff snap_files/ would compare all the snap files in snap_files.

Additionally, codediff can scrape files off of canvas LMS. Simply tell codediff where the canvas-generated html redirect files are with the --canvas argument. For example, run ./codediff --canvas canvas_html_files/.

Checkout the help (./codediff --help) for further reading.

Also, calling ./install will install codediff for the current user and add the startup executable to PATH.

Note: Currently, only APCSP Snap! xml files are supported.
