git-prompt - Minimal Git prompt

• Shows only the essentials to keep noise down to a minimum.
• Colors for quick assesment of the situation.
• Very fast: written in Go and compiled to native code. Calls only one external command. (Two if HEAD is detached.)
• Works with any shell that can call commands in a prompt.

Installing

First compile the program:

$ go build git-prompt.go

Then copy git-prompt to somewhere in your path and add this to the PS1 variable in your .bashrc / .zsh or other config file:

$(git-prompt)

Here's what I use:

PS1='\u@\h:\w $(git-prompt)$ '
