Git Bash Colored Branch Name On Mac Os X

I have moved recently to Mac OS X (10.8.2) and I am still using git-svn to work with our corporate repository with git. First of all I wanted to add git bash completion:

 curl https://raw.github.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash
 echo "source ~/.git-completion.bash" >> ~/.bash_profile"

Then I wanted to beautify command prompt and put this line to ~/.profile:

 export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\] \$ "

The next step was to add git branch name to the command prompt.

 curl https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh -o ~/.git-prompt.bash

Then put following line to the beginning of ~/.profile

 source ~/.git-prompt.bash

Next we need to modify the PS1 variable.

 export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\e[0;32m$(__git_ps1 " (%s)")\e[m \$ "

This will work, but only once! It evaluates expression for only one time. After googling around I have found that one of possible solutions is to escapte dollar sign (’$’) at the beginning of __git_ps1 invocation. However, this doesn’t solve problem and breaks PS1 at all. The solution is to use single quote characters to define string for PS1 variable. This tells bash to evaluate expression each time.

The working example:

 export PS1='\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\e[0;32m$(__git_ps1 " (%s)")\e[m \$ '

I haven’t found it in google, hope someone finds it helpful.
