brew install git bash-completion bash-git-prompt
Configure things:
git config --global user.name "Your Name"
git config --global user.email "[email protected]"
git config --global alias.co checkout
git config --global apply.whitespace nowarn
Setup an SSH key
ssh-keygen
Hit return a couple of times -- leave password blank if you want.
cat ~/.ssh/id_rsa.pub | pbcopy
Paste that code into your settings page on your repository host(s).
Get happy Git colors. Paste the following into your ~/.gitconfig file:
[color]
branch = auto
diff = auto
status = auto
[color "branch"]
current = yellow reverse
local = yellow
remote = green
[color "diff"]
meta = yellow bold
frag = magenta bold
old = red bold
new = green bold
[color "status"]
added = yellow
changed = green
untracked = cyan
Create a ~/.gitexcludes file and paste in this:
.DS_Store
There, now you don't have to ignore that every time.
Add the following to your ~/.bash_profile or ~/.bashrc:
source /usr/local/git/contrib/completion/git-completion.bash
source /usr/local/Cellar/git/2.12.2/share/zsh/site-functions/git-completion.bash
if [ -f /usr/local/share/gitprompt.sh ]; then
GIT_PROMPT_THEME=Default
. /usr/local/share/gitprompt.sh
fi
That will add tab auto-completion for Git branches, display the current branch on your prompt, and show a '*' after the branch name if there are unstaged changes in the repository, and a '+' if there are staged (but uncommitted) changes. It will look something like this:
[user@computer ~/Sites/example.com (master*)]$
If you want to have a different email address for a particular project (a personal project on your work computer, perhaps?), just run this command inside that project's folder:
git config user.email "[email protected]"
It's the same command as before, this time just omitting the --global.
