Git branch and dirty state in Bash prompt.

function parse_git_dirty {
  [[ $(git status 2> /dev/null | tail -n1) != "nothing to commit (working directory clean)" ]] && echo "*"
}
function parse_git_branch {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/[\1$(parse_git_dirty)]/"

git status --porcelain

Nice. How can I change the color of the branch to maybe light green?

@banta Use ANSI color escape sequences: https://www.google.se/search?q=bash+ansi+color+prompt

@banta This may be helpful: https://github.com/henrik/dotfiles/blob/master/bash/prompt.sh

thanks for this! my version of git prints out "nothing to commit, working directory clean", so change that string if your dirty checking isn't working.

Change nothing to commit (working directory clean) to nothing to commit, working directory clean if you're getting a persistent * even if your working directory is clean.

Thank you. Color coded branch name depending on state at https://gist.github.com/srguiwiz/de87bf6355717f0eede5 , green or red.

So I took this and improved on it a bit. Check it out here: https://github.com/jcgoble3/gitstuff/blob/master/gitprompt.sh This uses more reliable code that doesn't rely on a specific output that could change in a new version of Git, and is a bit cleaner and easier to read. Feel free to use it or improve on it more.

Works fine, edited slightly. git status --porcelain like @xbx suggested then changed the "nothing to commit (working directory clean) to nothing to commit, working directory clean" string to "". This makes it stable across Git versions and regardless of user configuration

Thanks for this! I added git status --porcelain to make things more robust, added in color per @srguiwiz's fork, and fixed an issue where colors weren't escaped (causing line-wrapping issues).

Updated color-coded branch here: https://gist.github.com/chrisnolet/46206e21d59f8250bb979a8516a9a034

This doesn't work anymore because git status ends with "nothing to commit, working tree clean" now (at least with my version).

You can replace the contents of parse_git_dirty with [[ -z $(git status --porcelain) ]] || echo "*"

git status --porcelain

function dirty(){
	if [[ $(git status --porcelain)  ]];
		then 
			echo "dirty"; 
		else 
			echo "clean" 
	fi
}

Another version for zsh (now the default shell on macOS) with color-coding: https://gist.github.com/chrisnolet/d3582cd63eb3d7b4fcb4d5975fd91d04

function parse_git_dirty {
        if [[ $(git status --porcelain 2> /dev/null)  ]];
                then
                        echo "*";
                else
                        echo ""
        fi
}

I appreciate that this old Gist still lures people in :)

These days I use Git's supplied prompt script with the GIT_PS1_SHOWDIRTYSTATE=1 setting: https://github.com/henrik/dotfiles/blob/602afb2644b61d0b1b82c09fabe94c60b9c29c74/bash/prompt.sh
