Java Git Overview

This is a personal project of mine where I attempt to answer the question "What if git was written in a much slower programming language?" :). In actuality my goal for this project was just to learn more about the inner workings of git and practice my Java skills.

This is not a one-to-one clone of git however as I only studied the general workings of git before trying to implement my own version (which is almost certainly flawed). I also don't think the code I have written is perfect (I have certainly repeated myself in a few areas). Still it has been a good project allowing me to learn more of the inner workings of git, filesystems, and Java.

Pitfalls to be aware of

I would NOT recommend using jit to track your projects. This is something I worked on for only ~1 month and certainly has bugs.

Known issues:

1. Handling deleted files is still an open issue
   • Something about the way I chose to implement the index file and staging area is making this a non trivial problem
   • Currently have plans for a specific function in Status command to detect when a previously tracked file has been deleted

How to use

1. Download the app.jar file from the folder gradle/app/build/libs/app.jar.
2. Run the jar file with java -jar /path/to/jarFile Main <option>
   • To see different command options just run java -jar /path/to/jarFile Main <option>

Future Work

1. Currently working on Checkout command to make the VCS complete. Should let users checkout a specific commit hash and rebuild their directory from it.
   • Future goals include adding a branching feature like git as well
2. Implement Log and Blame Commands to make it easier to review commit history
