# Git setup and configuration on Mac
# adapted from: http://arthurkoziel.com/2008/05/02/git-configuration/
#

# first install macports if you don't have it installed
#
#   http://guide.macports.org/#installing.macports

# make sure your local ports tree is up-to-date

sudo port selfupdate

# find out what version of git is available

port search git-core

# list the port variants available for git

port variants git-core

# install git and add the variants git-svn and git bash completion scripts

sudo port install git-core +svn+bash_completion

# you can add "+doc+gitweb" to get the html form of the documentation
# and the web application that will serve git

# Install bash completion:

cp /opt/local/etc/bash_completion.d/git ~/.git-bash-completion.sh
echo "[ -f ~/.git-bash-completion.sh ] && . ~/.git-bash-completion.sh" >> ~/.profile
. ~/.profile

# If you've already installed git using ports and want to know if there 
# is a newer version of git available

sudo port selfupdate
port outdated git-core

# Installing a newer version of git
# The old version is de-activated but will stay installed so it is 
# easy to deactivate the newer version and activate the older version 
# if that proves necessary.

sudo update git-core +svn+bash_completion
