It is very powerful and promising, but to really +get off the ground two features are missing: automated testing and +documentation generation. + +Automated testing is necessary to ensure modifications to functionality +don't break other functions within the library. There is already some +Automated Testing of the “snippets” repository with Github's Travis +server, but this has to be reconsidered and extended to cover the +standalone packages too. + +In order to be usable for a wider range of LilyPond users on a “consumer +level” openLilyLib needs proper documentation. This documentation has +to be generated from the sources, so a system is needed that requires +package authors to document the input files and provide additional usage +examples, from which documentation is generated. Ideally but not +necessarily this is implemented as a Git hook, i.e. automatically upon +each update to the repository. We don't prescribe the tools and +approaches to be used, but the most widely used language in the LilyPond +domain is Python, so there would be some bias towards that. +Alternatively a Scheme solution could be fine so generating the +documentation would actually be triggered by “compiling” a certain +LilyPond input file. In general it is advisable to make use of proven +concepts and tools from other languages. + +The eventual output of the documentation should be a static HTML site +that can be viewed locally and/or uploaded to a website.
