git
xcode-select: note: no developer tools were found at ‘/Applications/Xcode.app’, requesting install. Choose an option in the dialog to download the command line developer tools.
I did not install anything when the ensuing dialog appeared.
As Craig said, the answer is none. When you install Xcode, they are installed within Xcode, but it’s an extra step to have them installed separately – which you may need to do if you plan to use them from the command line.
I’m pleased to see that ruby is already installed without having to install the developer command line tools.
I new that “git” wasn’t going to be there it was ruby that I’m interested in. I was using an attempt to run git as proof that the developer command line tools weren’t installed and that situation was as I expected.
I searched for a listing of what command line tools are included when the developer tools are installed but I couldn’t find any information. Thus the request.
