Introduction

This is a skeleton page based on a discussion with Ratler on #lunar. Git can be easier than the man pages would suggest as long as someone shows you the way.

The page name is a bit naff - how about Git 101 for Lunar Developers or Sharing Git Repositories with Lunar Developers? Other ideas?

Please feel free to add comments/corrections - engelsman

Creating a local copy of the central moonbase repository

Git convention requires user name and e-mail address to appear in commit messages, etc. Note that the first two commands set these for all your repositories.

 satellite$  git config --global user.name "Full Name"
 satellite$  git config --global user.email "username@domain.name"
 satellite$  git clone git://lunar-linux.org/lunar/moonbase.git

If you are already a true Lunar developer, rather than an enthusiastic helper, you will need to do things slightly differently so that you can propagate your changes back to the central moonbase repository using your Lunar username and password [*]:

satellite$  git config --global user.name "Full Name"
satellite$  git config --global user.email "username@lunar-linux.org"
satellite$  git clone ssh://username@lunar-linux.org/var/git/lunar/moonbase.git

[*] Or is there a better way for setting the ssh username after the initial 'git clone git://...' ?

Tracking a Lunar developer's moonbase repository

Some developers have made their copies of their personal repositories, with branches, available at a central URL. [How?] If you wanted to access florin's repository, for example, you would first have to tell your own moonbase repository about it:

 satellite$  cd moonbase.git 
 satellite$  git add remote florin git://foo-projects.org/florin/moonbase.git
 satellite$  git fetch florin

Creating a local branch copy of a Lunar developer's branch

 satellite$  cd moonbase.git
 satellite$  git branch -a               # should show remote/*/* branches
 satellite$  git checkout -b florin remotes/florin/florin

If you look in .git/config you should now see:

1. You have a new remote section pointing at florin's url;
2. You have a new branch named florin that refer to refs/heads/florin.

Copying/updating files from a remote Lunar developer's branch

 satellite$  cd moonbase.git
 satellite$  git checkout florin
 satellite$  git pull                    

Adding a new branch from a remote Lunar developer's repository

 satellite$  cd moonbase,git
 satellite$  git checkout florin
 satellite$  git remote update florin     
 satellite$  git branch -a               # should now show new 'xyz' branch
 satellite$  git checkout -b florin_xyz remotes/florin/xyz
