Requirements

Requires Python version >=3.6. Get all the other requirements using pip install -r requirements.txt in the root folder.

How to Run

In the root folder, edit runPlagGen.py line 4 in order to set your project path. Note that a single python file is supported for this version of work. Modification of hyperparameters can be done in /metaheuristics/GA/GAOptimizer.py line 18 through 22. Then run the file to see tons of refactored codes being stored in /temp.

python3 runPlagGen.py

Running above code will take some time depending on your specifications, and will yield pareto front of the best individuals after it's done.

Adding new software similarity measurements

We are currently using MOSS(https://theory.stanford.edu/~aiken/moss/) or pycode-similar(https://github.com/fyrestone/pycode_similar.git).

CustomRefactorer

Implementing new refactorings

New refactorings should subclass RefactorOperator and implement the specified methods (Look at ForToWhile.py for an example).

You will also need to add the refactorer to the _operation_classes list in CustomRefactorer.

test_refactoring.py can be used to test the implemented refactorings. Change the specified constants at the top of the file to test your implementation.
