Cohesion value interpretation (Using lcom)

Score:

• ==1 - indicates a cohesive class, which is the "good" class;
• >=2 - indicates a problem. The class should be split into so many smaller classes;
• ==0 - happens when there are no methods in a class. This is also a "bad" class.

Overview

The tool has been tested on windows 64bit and ubuntu 64bit. Currently, AC2 only supports python3 projects.

Installation

Clone or download this github repository:

git clone https://github.com/dheerajrox/AC2.git

Get into the main directory:

cd AC2/src/main

Install the requirements:

pip install -r requirements.txt

Usage example

To start the server use the following command:

python main.py

Then, open your browser to 'http://localhost:5000/'

Enter a Python Github Repository link and press enter to generate annotated graphs in available views.

Compare two different versions of a repository by their respective annotated call graphs and collaboration graphs

Results

We have evaluated 10 repositories using AC2. For each repository, we have compared its first release with its subsequent releases. Results
