I have a question: Does Lilypond have an API that can be simply called from other programs to render some markup (stored as a string) into a SVG file?
We want to use Lilypond in an Unity app/game, wich will be used by many musicians and thus requires some decent staff rendering. We basically program in C#, but there is an easy bridge to interface with C/C++ libraries. So calling an API should not be a huge problem, but does it even exist and is documented somewhere?
I asked in the IRC a few hors ago, and received a brief "No, it doesn't exist". Bit is that really the abrupt end of the story, or is there some other possibility to call Lilypond from an external program?
