Prompt for command line including git branch

in my .bashrc in ~ Put the following:  

#⚡ cat .bashrc
export EDITOR=/usr/bin/vim

if [ -f /opt/local/etc/bash_completion ]; then
        . /opt/local/etc/bash_completion
fi

set -o vi

alias ll='ls -l'

showBranch(){
    if [$(pwd | grep "projects|www") != ""]; then
        git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/±\1/' | tr "\n" ' '
        hg branch 2> /dev/null | sed -e 's/\(.*\)/☿\1 /'
    fi
}

export PS1='\e[01;32m\u\e[34m@\H \e[01;31m\w \e[32;40m$(showBranch) \n\[\e[30m\]#\[\e[33m\]⚡ \[\e[0m\]'
