### Aliases for git

# An alias to display all git aliases in our .gitconfig
alias galias="cat ~/.gitconfig | sed -n '/alias/,/apply/p'"

# https://gist.github.com/mwhite/6887990
# A function allowing us to call git aliases defined in our .gitconfig by using
# a 'g' prefix, rather than 'git', e.g.
# gla      # the short version 
# git la   # instead of this longer version

# For linux:
# if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
#    . /etc/bash_completion
#fi

# For Mac OSX:
#     brew install bash-completion
if [ -f $(brew --prefix)/etc/bash_completion ]; then
. $(brew --prefix)/etc/bash_completion
fi
