This repository contains a set of Python scripts I've found useful for preprocessing student's submissions before running them through Moss.

• extract.py: recursively iterates through all archive files in a directory and extracts them into a subdirectory with the corresponding name. Requires the Python unrar module to be installed, which requires the unrar library to be available on your system.

• cat-dirs.py: goes through each subdirectory in a directory, concatenating all source files in that subdirectory (and its child directories, recursively) into a single source file. Useful if each of your students' programs is in a different, named subdirectory.

• replace-spaces-in-filenames.py: goes through all files in a directory and replaces spaces in the filenames with underscores (_). Useful since the Moss upload script doesn't seem to work very well with files with spaces in their name.

The scripts are set up for processing C++ source code, but can be easily adapted to work with any other programming language (just change the list of file extensions).

These scripts are MIT licensed, see the LICENSE file for details.
