Dear all, [...]2) I tried the OpenLilylib package. I wasn't familiar with that tool and had to struggle a bit with the installation. But still, with the export-example.ly seen in the manual, I get this error message: | GNU LilyPond 2.22.2 | Traitement de « export-example.ly » | Analyse... | | oll-core: library infrastructure successfully loaded. | Interprétation en cours de la musique... | init exportHumdrum: "export-example.krn" | init Staff 1 | init Voice 1/1 (1) | init Voice 1/2 (2) | init Staff 2 | init Voice 1/ (3) | init Voice 2/ (1) | init Voice 2/mel (2)/home/remy/.config/lilypond/openlilylib/lilypond-export/api.scm:278:48: In _expression_ (ly:grob-properties grob): | /home/remy/.config/lilypond/openlilylib/lilypond-export/api.scm:278:48: Unbound variable: ly:grob-properties And I only get the PDF as an output. I don't know what I missed here?
This sounds like this OLL package has not been updated for LilyPond
version 2.22.
6) Last point: I made some month ago, a short presentation and introduction to LilyPond for my colleagues in my music institution. Beyond the fact it was quite a challenge to try and convince them of the utility to take some time and learn that great tool, I received that question I couldn't answer at the time: is it possible to import or export in XML? I haven't have a use for that kind of feature until now, and I don't know how the commercial softwares handle that, but still, wouldn't that be a great argument to convince the people to go for it? Final thought, I don't know how Urs did manage to convince publishers about LilyPond and what responses he got (I would be curious though), but I am pretty sure that kind of limitation in importing/exporting in XML would be nowdays a dealbreaker for publishing companies, don't you agree?
A MusicXML export integrated into LilyPond has been discussed repeatedly,
and everybody agrees that it is desirable, but it has not been implemented
so far because, well, it's quite easier said than done. In a free (libre)
/ open source project, the only way to be sure something will get done
is to do it yourself.
