jianpu-ly is a Python program (compatible with both Python 2 and Python 3) that assists with printing jianpu (numbered musical notation) in the GNU Lilypond music typesetter. ​The jianpu is written on a modified-appearance “stave” in Lilypond, which means Lilypond’s typesetting capabilities (lyric spacing, slurs, beams etc) will apply to the jianpu without needing to add a 5-line stave. ​If you prefer, the generated code for the jianpu stave may also be placed in a score with other types of stave.
