or just 

function fish_prompt --description 'Write out the prompt'
        # Just calculate this 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 set -q VIRTUAL_ENV
        echo -n -s (set_color red) "(" (basename "$VIRTUAL_ENV") ")" (set_color normal) " "
    end

    set -l color_cwd
    set -l suffix
    switch $USER
        case root toor
            if set -q fish_color_cwd_root
                set color_cwd $fish_color_cwd_root
            else
                set color_cwd $fish_color_cwd
            end
            set suffix '#'
        case '*'
            set color_cwd $fish_color_cwd
            set suffix '>'
    end

    echo -n -s "$USER" @ "$__fish_prompt_hostname" ' ' (set_color $color_cwd) (prompt_pwd) (set_color normal) "$suffix "
end

and you're good to go
