MusicXML-Import scheint buggy zu sein

[Köbi]

Hallo zusammen

Beim Importieren von MusicXML wird ein fehlerhaftes ly-File erstellt. Bei Texten (Strings) ist jedes zweite Zeichen ein hexadezimales Null (x00). Unicode? Frescobaldi kann damit allerdings nicht umgehen, es verhaut ihn. Das Problem tritt zumindest mit den Versionen 2.19.46 und 2.19.47 auf. Mit 2.18.2 funktioniert alles wie es soll. Das MusicXML ist von Capella exportiert worden und sieht korrekt aus. Ich habe es als Anhang beigelegt. Kann jemand das Problem reproduzieren? Dann würde ich versuchen, einen Bug zu erfassen.

Gruss, Köbi

Also ich habs jetzt mit 2.18.2 probiert. Terminal nicht Frescobaldi.

Mit 2.18.2 funktioniert alles wie es soll

Kann ich wirklich nicht bestätigen. Mit 2.19.48 hab ichs dann gar nicht erst probiert

Das pdf aus dem entstandenen ly-file ist auch nix.

Bei soooo heftigen allergischen Reaktionen ist für gewöhnlich schon der input kaputt.

Hallo Harm

Bei mir reagiert es definitiv anders. Beiliegend die ly-Files, die mit 2.18.2, resp. 2.19.48 erzeugt werden. Das 2.18.2-File sieht doch durchaus Ok aus.

Kann vielleicht noch jemand anders versuchen, das oben angehängte MusicXML mit den beiden Versionen zu importieren? Danke.

Gruss, Köbi

[fugenkomponist]

Ich kann harms Antwort für 2.18.2 nur bestätigen: das musicxml2ly-log sieht genauso aus, das lilypond-log ist ebenfalls furchtbar (lauter angefangene Balken, die nicht beendet werden, falsche Takt- und Taktzahlüberprüfungen, dadurch nicht mögliche erzwungene Zeilenumbrüche etc.) und das PDF sieht auch kaputt aus. In 2.19.47 sieht das musicxml2ly-log inhaltlich ähnlich, aber länger aus, lilypond bricht ab, weil ein String nicht beendet wird.

Hallo Köbi,

weitere Tests:

Ich habe musicxml2ly angewendet auf Dein IMSLP-xml-file, sowohl mit 2.18.2 als auch mit 2.19.48.

Beide musicxml2ly-Versionen geben im log einen Haufen von Warnungen, schreiben aber ein lesbare ly-files.
Diese ly-files compilieren ebenfalls mit einem Haufen von Warnungen. Tatsächlich ist das 2.19.48-pdf aber etwas besser, wenn auch ebenfalls unbrauchbar.
Wie schon gesagt halte ich das IMSLP-xml-file für kaputt.

Aber keine Fassung liefert ein unlesbares ly-file, wie bei Deiner 2.19.48-Fassung.
Ich bin auf 64-bit Ubuntu.


Da es in letzter Zeit zahlreiche Änderungen gegeben hat, die hier ins Spiel kommen könnten, wäre ein weiteres testen schön.
Um einen möglichen bug zu verifizieren oder zu falsifizieren, mache weitere Tests bitte nur direkt im Terminal, ohne Frescobaldi (um einen Einfluß von dort auszuschließen).
Gerade weil Du auf windows bist, iiuc, sind Deine Ergebnisse interessant.

Falls es sich um einen bug handelt, sollten wir versuchen ein minimal-Beispiel zu bekommen.
Versuch doch mal folgenden xml-code mit 2.19.48-musicxml2ly zu bearbeiten.
(Stammt von der musicxml-home-page, deren "Hello world"-code)

Und berichte bitte was passiert.

P.S.
lilyponds musicxml import ist generell verbesserungs-würdig.
Und ein export ist momentan überhaupt nicht codiert, Frescobaldi hat aber ein entsprechendes feature (wird aber selbst von deren Entwicklern momentan noch als experimentell bezeichnet).
Tatsächlich ist das xml-format an sich m.E. noch nicht ausgereift, sondern hängt viel zu sehr davon ab wie versiert der Ersteller mit dem jeweiligen Notensatzprogram ist.
Der Denemo-Entwickler hat versucht mit diesen Unwägbarkeiten bei xml-files besser umzugehen, was letztlich zu einer eigenen xml-Variante geführt hat, iirc.
Scheint aber besser zu funktionieren als anderes. Wäre vielleicht eine Möglichkeit!?
