haskell-refactor-tool

This is a prototype which was made in the context of a research on automatic code refactoring for the GIICIS group.

Features

Libraries

This tool uses two main external libraries.

• Homplexity for measuring code quality.
• Haskell-Tools for applying refactors with the tool HT-Refact.

Modes

Three modes:

• Interactive. Accept or deny a sorted list of refactors manually.
• SA (Simulated Annealing). Automatic code refactor using SA algorithm. (Not completed)
• Random. Automatic code Refactor using random algorithm.

Limits.

• Can refactor a few types of code-smells. This is because there aren't many possible refactors. However this can be fixed if other tool is used or by developing new refactors for Haskell-Tools library.
• Refactor one file at the time.

Usage

We have created a Dockerfile that contains the exact versions of the libraries required for running this script and it's uploaded to this repository.

Building image

docker build . -t refactor-image

Using the container (example).

Mount a volume that contains both the code you want to refactor and all the scripts in this repository.

docker run -v ~/code:/code -ti refactor-image  /bin/bash
cd code
python3 main.py --file haskell/Main1.hs --iterations 1 --type manual --maxTempIterations 50

This is not ideal. The building process can take some time and the image is heavy but it's a temporary solution that we have used. We will improve this.
