Add jianpu support

[jhuang97]

Jianpu is a musical notation system using numbers, which is popular in China and elsewhere. I have previously used some web app that can edit and display jianpu along with song lyrics; it had its own special markup language. For me, it would be nice to be able to edit jianpu scores in Musescore and switch a staff between jianpu and staff notation.

There have already been multiple attempts at implementing jianpu in Musescore:

• Efforts in 2017-2018. Added a new StaffGroup and StaffType for jianpu, and created several new classes for elements of jianpu notation, including Jianpu notes and chords. However, these changes were on top of a much earlier version of Musescore. 141581 jianpu #2957, fix #141581: Jianpu linked staff display and saving to XML score file #3614
• More recent attempt by Auase, getting as far as rendering single-line Jianpu. First pull request: Realize the basic functions of Jianpu #19395. Second pull request with much discussion: Realize the basic functions of Jianpu #19421.

The current status about Jianpu is that Auase had created those PRs you mention, but those could not directly be merged because they needed to be improved (at least code-technically). Auase is planning to work on these PRs again in the future, but is currently busy with other things, and not yet sure when he/she has time to come back to it.

We will wait patiently and hope it can be realized as soon as possible

In case anyone wants a hacky workaround, here's a plugin MuseScore-Integer-Notation

[jhuang97]

That looks pretty cool, even though it's not exactly the same as jianpu

[jhuang97]

When you re-position the notes vertically, you align the top notes, not the bottom notes. Is the idea that the top notes are more likely to be the melody notes?

[King-of-Infinite-Space]

Honestly I didn't think much about it, but your interpretation sounds reasonable. Could make bottom align an option next time.

Not sure if there's been any progress on this, but Muse VP of Product Tantacrul released a video 'Notation Must Die: The Battle For How We Read Music' on his YouTube channel in November 2023. It has a brief clip showcase of jianpu support in Musescore.

At that time, it was 'in development', but I'd love to know where it's up to now 1.5 years later. It seems the latest version doesn't have the functionality enabled yet.

EDIT: after doing some more searching, it was likely linked to the closed PR #19421, so progress seems to have stalled.
