Amarok is now developed in a Git repository instead of SVN. This was done to help get into place all the needed infrastructure to convert all of KDE, including documentation.

Amarok/Development/Git contains the most up-to-date information on Amarok related git topics. KDE Git page also provides more details.

Basic Development

90% of the time this is all that is needed:

git pull --rebase
#hack, compile, build. It works!
git status #to check if you want to commit all the modified files
git commit -a
git log
git push

git pull --rebase downloads the latest changes. The --rebase option takes any unpushed local commits and applies them to the latest code, moving it to the top of the history. It is the equivalent of git pull; git rebase origin/master. See the "1. Rebase" section of Shipping Quality Code for a good explanation of what rebase does.

If you have uncommited changes you can not rebase. Instead you can git stash, do the rebase, and then git stash apply.

git status will tell you what files are modified. If you created a new file, use git add on it to "track" it. If there are some junk files, you can add a regexp to .gitignore in the root.

git commit -a will commit all unmodified files. You can use git add and then simply git commit instead if you wish to commit only certain files.

Use git log to review the local unpushed commits. Possibly also useful is git diff origin/master, which will give you a diff between the current checkout and what is in the central repo.

git push pushes all the local commits to the central repo.

Follow remote feature branch

With git, feature branches are cheap and easy. Here's how to follow a feature branch someone else has already setup.

Remember that you can't push to git:// URL's when picking what URL to use.

git remote add jeff git://git.kde.org/clones/amarok.git/mitchell/pudaction.git
git remote update
git branch -a
git branch jeff-pud jeff/pudaction-removal
git checkout jeff-pud
#and later you want to switch back to the mainline
git checkout master

git remote add adds a new remote named 'jeff' with the given URL. Think of remotes like bookmarks: you could always just explicitly pull from a URL instead.

git remote update downloads all the remotes you have without merging them, including the remote you just defined. This is a handy command if you're tracking multiple remotes.

git branch -a this lists all the branches you have, including the remote branches. Find the new branch you want to look at.

git branch this command creates a local branch called 'jeff-pud' that tracks the remote branch 'pud-action/pudaction-removal'. You figured out the name of the latter in the previous command.

git checkout is how you switch between branches.

+=== Basic Development  ===
- git clone git://gitorious.org/amarok/amarok.git
-This creates an 'amarok' directory. cd into that and use it like normal. And when you want to update:
- git pull
-will download the new changes.
-== Getting started for Developers ==
+% of the time this is all that is needed:
-===gitorious.org account setup===
+ git pull --rebase
+ #hack, compile, build. It works!
+ git status #to check if you want to commit all the modified files
+ git commit -a
+ git log
+ git push

-* Create an account on [http://gitorious.org gitorious.org] the git hosting service used by Qt and now Amarok.
+= Follow remote feature branch =
-* On your user page, (that's at http://gitorious.org/~your_nick) click on "Manage SSH keys" and add your SSH key.
+With git, feature branches are cheap and easy. Here's how to follow a feature branch someone else has already setup.
-* Again from the user page, click on "Manage aliases" and add any email addresses you've ever used in KDE SVN. This way any commits you've made in the past are tracked back to you. If your gitorious email address is the only one you ever used, then this step isn't needed.
-* Request one of the kde-developers admins to add your username to the group (the same rules apply as KDE SVN account requests). This will give you push rights to Amarok. Lydia, Ian and Jeff are all admins.
-===Setup Amarok Clone===
+Remember that you can't push to git:// URL's when picking what URL to use.
-Gitorious has one address for cloning, and another for pushing. The pushing address can be used for cloning, so the easy thing to do is just use that.
+ git remote add jeff git://git.kde.org/clones/amarok.git/mitchell/pudaction.git
+ git remote update
+ git branch -a
+ git branch jeff-pud jeff/pudaction-removal
+ git checkout jeff-pud
+ #and later you want to switch back to the mainline
+ git checkout master
- git clone git@gitorious.org:amarok/amarok.git

+''git checkout'' is how you switch between branches.
- git commit -a #the -a option commits all modified files. use git add to select them individually
-  git push
