Hi,Paul!
I am impressed by your code! You have really made things automated! To note
about improvement, accidentals in jianpu look identical to those in standard
notation, but the baseline is about 0.75 height position of numeric note head
height button up. Lines indicating duration (aka. beams) should be horizontally
linked together the same way as 5-stave notation.
I have tried changing "\key c \major" to "\key d \major", and found that rules
dealing with accidentals are still in the old way(eg. the second note should be
flat-7, not natural-7).
Thanks!
David Zhang

I went ahead and worked some more on this. (It took me long enough to figure
out how to do this stuff, so I might as well put it to use so others can
benefit too.)
See the attached file for another revision that implements these things:
- dots indicating octaves
- lines indicating note and rest durations
- correctly determines Jianpu note number (c major key: c = 0, c minor key: c =
6, etc.)
It works by incorporating these symbols into the note head stencil.
This is just a quick sketch that can be improved and refined in terms of
spacing and other details. Some things still to do are handling dotted notes
(I haven’t been able to access the dots grob from note head grob, so this seems
tricky) and Jianpu accidental signs (which will require their own engraver).
HTH,
