I thought of the edition-engraver as well. Has a plethora of features and is used by people doing large real world type-setting. Nevertheless here some coding, returning at least a little tracking info. Though, it's a crude coding and expensive, use at own risk ;) \version "2.19.64" remark = #(define-music-function (strg)(string?) #{ \withMusicProperty #'remark #strg <> #}) %% writes remarks to <your-file-name>-remarks.txt writeRemark = #(define-void-function (mus)(ly:music?) (music-map (lambda (m) (if (and (music-is-of-type? m 'event-chord) (ly:music-property m 'remark #f)) (let* ((log-file (format #f "~a-remarks.txt" (ly:parser-output-name))) (port (open-file log-file "a")) (origin (ly:music-property m 'origin))) (format #t "\nRemark from ~a written to: ~a" origin log-file) (format port "\n~a:\t~a" origin (ly:music-property m 'remark)) (close port) m) m)) mus) mus) \writeRemark { \remark text c4 d e f \remark more-text g a b c \remark "further text: pitch is d, length 4" d e f g } Cheers, Harm _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
