Git prompt build with Go

I had a git prompt built with Bash, but I wanted to use a language with easier string and variables manipulations. It was important to still have a prompt with great performance, so I used Go.

main R[-0|+1]  # If you're on the [default] main branch, only diff with your current remote, origin/[default]
feature* R[-1|+3] M[-2|+3]  # On a different branch with its own remote branch, diff with both the remote R and default main M
new-feature M[-2|+3]  # On a different branch without its own remote branch, diff with only the default main M
main*  # When the repo is only local, no diff

Installation

Clone this project and then run go build. Make sure the binary is in your path, and then call it in your custom bash prompt with $(gogit-prompt).
