SupertTuxKart uses git for source code, and SVN for data files. So if you don't have those, install them first.
The core code repository is hosted on our github page. Example clone command:
git clone https://github.com/supertuxkart/stk-code.git stk-code
It is about 130 MB in size.
Data files are hosted on sourceforge and use SVN. Example checkout command :
svn checkout https://svn.code.sf.net/p/supertuxkart/code/stk-assets stk-assets
It is about 650 MB in size.
These two repositories should be downloaded in the same folder, so that folders "stk-code" and "stk-assets" are next to each other.
The media repository is not required to play the game. It contains the source files for assets (blender files, lossless music and sound files, etc.) and is meant for artists. It is around 1.5GB in size.
The media repository is hosted on sourceforge and uses SVN. Example checkout command :
svn checkout https://svn.code.sf.net/p/supertuxkart/code/media/trunk stk-media-repo

Here are some guidelines for developers who have write access to git/SVN. These guidelines may change over time, esp. if we get more developers working at the same time, and if we get closer to a release. The development trunk is considered to be pretty unstable (though see below for guidelines). Some of the recommendations are done based on the fact that there are not many developers, but many people "play-testing".
- Subscribe to the STK-development list (see Community). Developers usually post what they are working on here, so that the likelihood of conflicts can be decreased. Additionally, known high-profile bugs are posted here, too.
- It might be worth subscribing to the stk-commit email list (see Community). All commit messages are automatically sent to this address, so you will always be aware of what is happening, and if your work interferes with what other people are doing.
- The development version should always compile. While it's not possible to test on all platforms, do your best to write portable code. Other developers and testers will usually quickly point out (and fix) any problems.
- Commit frequently. Frequent commits have the advantage that they act as a backup (some people have lost their work because of a harddrive crash), and they make time consuming conflicts less likely.
- Test your commits to make sure they do what they are supposed to do. It might not possible to do very thorough tests (e.g. a single change of a physics parameter means that you would have to race each kart - potentially on each track), so listen for bug reports from testers. It might be worth even asking for specific feedback from testers.
- Make sure that at least normal racing always works. This is the functionality other developers most likely need. If there is a known minor problem (e.g. 'restarting' might not work), post this to the mailing list to avoid unnecessary bug reports, or put it in the bug tracker if you are not going to fix it quickly. These kind of minor known bugs are acceptable during most of the development cycle. When getting closer to a release, we switch to bug-fixing mode and avoid committing new features that can introduce bugs.
- Try to include all changes for a single feature in one commit (i.e. don't commit each file separately, and try not to mix several features in one commit - though the latter is acceptable since it might be a lot of work to split a change set into different commits).
