In order to build score, follow the documentation.
When updating the score repository through the command line, don't forget to update the submodules, they change often.
cd score
git pull
git submodule update --init --recursive
Some useful and easy potential contributions are listed on the website.
There are also many fixable areas in the code :
- TODO : for simple issues.
- FIXME : for critical bugs / problems.
- MOVEME : when something is not where it should be.
- REMOVEME : when something is redundant.
- RENAMEME : when the class does not match with the file it's in.
- OPTIMIZEME : when an easy-to-write-but-suboptimal algorithm is used.
Finally, one can write its own score plug-ins to add custom features to the software. An example plug-in with the most common classes reimplemented is provided here.
