A clone of the git vcs written in Go.
This work is based on the book Building Git by James Coglan. This book is excellent and I highly recommend it!
I will try to tag the repository state according to the chapter titles.
This year I've been working on improving my understanding of git. Like many developers, I've long survived on just enough git proficiency to scraped by. But I wanted to get better.
The first thing I did was spend some time learning interactive rebasing. That was a big leap forward. I also bought Katie Sylor-Miller and Julia Evans' zine Oh Shit, Git!. It's a great primer and cookbook for working with git, and fun to read as well!
But I wanted to really understand git's internals better, and I also like coding projects, so when I saw James's book, I bought it immediately.
I'm not a huge fan of Ruby, and I work professionally in Go, so I thought it would be really fun to read the book and implement git in Go as I read. An advantage of doing this is that I don't have to resist the urge to just copy/paste the code examples into my project — they ain't gonna compile. And Go and Ruby are very different languages, so there really wasn't a temptation to just transliterate James's Ruby code into Go.
This process has been really challenging and extremely rewarding. I'm less than a third of the way through the book (unless this README has gone stale) and I already feel like I've leveled up my understanding of git internals multiple times. In addition, I'm learning aspects of Go that I haven't encountered personally or professionally, so win win!
I am also interested in (finally) learning Rust, so I'm eyeing a future project of doing this all again in a new language! :D

Just like using git, except it's buggy and most of the features aren't implemented!
