hi- i'm writing some software that generates .ly files and want to offer the option to automatically add (woodwind) fingering chart annotations to the engraving. the project is in haskell and i'd rather not learn scheme or lilypond internals. the problem is determining the octave -- i want to support relative octave entry (http://lilypond.org/doc/v2.18/Documentation/notation/writing-pitches#relative-octave-entry), but i don't want to reimplement relative octave detection (not because it's hard, but i in principle don't want to duplicate logic).
i would think automatic fingering annotation would be a desirable feature in lilypond itself -- perhaps a markup flag where i request the standard fingering for the note, maybe some way of selecting a predefined alternate fingering (nice to have would be rules for determining prefered fingerings from the previous note, a way to define fingering libraries to choose from, etc). i assume that wouldn't be anyone's priority to implement, so either i could try to myself from within lilypond, or (my preference) i need some way to ask lilypond for the octave -- either an API or command-line program or something where i give an .ly snippet and lilypond gives me back the absolute pitches. what do you think would be the best way? thanks! -erik _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
