I have the script setup in my .bashrc file which gives me the useful git information in my prompt. This is great for small repos, but when I cd into a large repo, it can take a 30+ seconds, for the prompt to respond since it needs to review the git repo first.

It is possible to set up my .bashrc so that I can either whitelist my small repos for the git prompt to display, or blacklist my large repos so it doesn't load the git prompt?
Alternatively, I'd be happy with a flag/variable that I have to set to enable the git prompt.

The relevant part of my .bashrc looks like this:

# Git prompt options
source ~/

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]$(__git_ps1 " (\[\033[01;33m\]%s\[\033[00m\])")\$ '
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(__git_ps1 " (\[\033[01;33m\]%s\[\033[00m\])")\$ '
unset color_prompt force_color_prompt

Look at the code - the real work is done in a function __git_ps1, which is called from inside the prompt.

Replace this function by your own function, e.g.

# this is only a outline of possible code 
function myFancyGitPS1() {
   case $(pwd) in
           __git_ps1 " (\[\033[01;33m\]%s\[\033[00m\])"
