Contributing
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.
