This is a module separated from WhoTouchedWhat. ModularityChecker analyzes the overall dependency between given modules by seeing how many changes are within a modules and how many crosses multiple modules.
In order to use this checker, you can run mvn install to generate the corresponding jar file.
Then run java -jar .\target\ModularityChecker-1.0-SNAPSHOT.jar .. The argument taken here is the address
at which your meta_data.json locates. You can also specify other root directory.
Inside meta_data.json, specify your repository address which you cloned locally, and the modules you want to analyze. The modules field
is a 2d array, each array inside is a module containing a series of files/folders which you consider belonging together.
All the address are separated by '/'.
A sample of meta_data.json is provided here. After the checker finish analyzing, it generates a
info.json under the same directory which you specified in the argument, containing a total modularity score,
which is the ratio of number of changes across modules (extra) to the number
of changes within one module (intra). It also tells you the contribution (total line changes) of each author towards each module.
