About

The Software Systems Laboratory (SSL) Git Bus Factor Project is a python tool that lets users calculate and graph the bus facto of a git repository. This tool relies on the output of the Git Commits LOC project.

This project is licensed under the BSD-3-Clause. See the LICENSE for more information.

Developer Tooling

To maximize the utility of this project and the greater SSL Metrics project, the following software packages are required:

Operating System

All tools developed for the greater SSL Metrics project must target Mac OS and Linux. SSL Metrics software is not supported or recommended to run on Windows but can be modified to do so at your own risk.

It is recomendded to develop on Mac OS or Linux. However, if you are on a Windows machine, you can use WSL to develop as well.

How To Use

Installation

You can install the tool via pip with either of the two following one-liners:

• pip install --upgrade pip ssl-metrics-meta
• pip install --upgrade pip ssl-metrics-git-bus-factor
