Amarok/Development/Hacking On Amarok HowTo

How to become involved

Most discussion regarding Amarok development happens in IRC. Join us in #amarok on irc.freenode.net.
Join the mailing list.
Read everything in the HACKING folder. It goes over the Amarok coding style and other important information.
Submit your patch. There are several channels to do so:

Bug Tracker: Search for the problem you are solving on KDE's bugzilla and attach the patch. If there isn't a bug for it yet, create a new bug or wishlist and then attach the patch.
IRC: IRC has the advantage that a developer might happen to be online and has the time to test your patch, it could be applied immediately or give immediate feedback.
Mailing lists: Things often get overlooked in the mailing list, so do not rely on it. However it is a good method of bringing up a subject with the development team.

Install the KDevelop IDE (Integrated Development Environment). You should use your distribution's package, or build using Konstruct.
Fire up KDevelop and from the "Project" menu, select "Open Project...", then choose the amarok.kdevelop file from the extragear/multimedia/amarok/ directory.
Compile Amarok normally once through the standard means.
From the "Build" menu select "Build Project" to build Amarok after you have made changes.
To find the source of a particular feature, a good method is to find an English string associated with the feature and then search for it via "Edit" → "Find in Files".
