Git prompt for bash

Bash prompt written in pure bash script.

Under the hood the git prompt provided by git is used. As that script does all the logic already, but outputs a rather cryptic status line, the only thing this script does is replace the output by more intuitive icons.

Comparing the output of this script...

master ✕✓? ↑1↓5

...with the original git prompt

master *+% u+1-5

Usage

1. Download the script

   curl https://raw.githubusercontent.com/koffeinfrei/bash-git-prompt/master/bash-git-prompt > ~/.bash-git-prompt

2. Add the following to your .bash_profile (or .bashrc or whatever bash initialize script you use):

   # 1. Exposes the function `__git_ps1_improved`
   source ~/.bash-git-prompt
   
   # 2. Include the function `__git_ps1_improved` in your `PS1`.
   #    This is just an example of a prompt with `\w` outputting your current
   #    directory.
   PS1="\w $(__git_ps1_improved) ➜ "
