Show git branch name in fish shell

Browsing the web I found this fish shell function to show the current git branch in the fish prompt .

Add the following function in your ~/.config/fish/config.fish file

function fish_prompt --description 'Write out the prompt'
 # Just calculate these once, to save a few cycles when displaying the prompt
 if not set -q __fish_prompt_hostname
 set -g __fish_prompt_hostname (hostname|cut -d . -f 1)
 end

 if not set -q __fish_prompt_normal
 set -g __fish_prompt_normal (set_color normal)
 end

 if not set -q __git_cb
 set __git_cb ":"(set_color brown)(git branch ^/dev/null | grep \* | sed 's/* //')(set_color normal)""
 end

 switch $USER

 case root

 if not set -q __fish_prompt_cwd
 if set -q fish_color_cwd_root
 set -g __fish_prompt_cwd (set_color $fish_color_cwd_root)
 else
 set -g __fish_prompt_cwd (set_color $fish_color_cwd)
 end
 end

 printf '%s@%s:%s%s%s%s# ' $USER $__fish_prompt_hostname "$__fish_prompt_cwd" (prompt_pwd) "$__fish_prompt_normal" $__git_cb

 case '*'

 if not set -q __fish_prompt_cwd
 set -g __fish_prompt_cwd (set_color $fish_color_cwd)
 end

 printf '%s@%s:%s%s%s%s$ ' $USER $__fish_prompt_hostname "$__fish_prompt_cwd" (prompt_pwd) "$__fish_prompt_normal" $__git_cb

 end
end
