A few days ago I was looking for something, and stumbled across
https://lsr.di.unimi.it/LSR/Item?id=1017
And I thought that it might help here. I was able to modify it a bit to
pare down the info it returns, as it returns *everything* about each
occurence of the grob in question. The result:

\version "2.25.10"

#(define print-all-script-priority
   (grob-transformer 'after-line-breaking
 (lambda (grob orig)
   (format #t "\n~a:" grob)
   (format #t "\n~a:" "Text-Interface")
   (format #t "\n\t~a:  ~a" "text"
   (ly:grob-property grob 'text))
   (format #t "\n~a:" "Text-Script-Interface")
   (format #t "\n\t~a:  ~a\n" "script-priority"
   (ly:grob-property grob 'script-priority))
   )))

grobPropertiesInfo =
#(define-music-function (grob-name)(symbol?)
   #{
 \override $grob-name . after-line-breaking =
 #print-all-script-priority
   #})

\relative c {
  \set strokeFingerOrientations = #'(up)
  \set fingeringOrientations = #'(up)

  \grobPropertiesInfo #'StrokeFinger
  \grobPropertiesInfo #'Fingering
  

  \override Fingering.script-priority = #118
  
}

This produces the output:

It seems to me, that in order to make this work, two things need to
happen:

1. The whole score collection has to be traversed and \midi counted
   This could be done via toplevel-score-handler and some global
   variable.

2. If there are no midi blocks, add one.  This is tricker.  Assuming
   there is a toplevel-of-everything-handler, it would be necessary
   to find a score (which one though?) and then add a midi block.


I took a shot at the first one:

#(define midi-count 0)

#(define (has-midi? score)
 (any (lambda (x) (ly:output-def-lookup x 'is-midi #f))
  (ly:score-output-defs score)))

#(define (count-midi-in-score score)
   (if (has-midi? score) (set! midi-count (+ midi-count 1)))
   score)

toplevel-score-handler =
#(lambda (score)
   (collect-scores-for-book (count-midi-in-score score)))

midi-count now contains the right number.

What can I do with it?

Yes, sorry.

I wouldn't call it a “proper” fix because it's a bit too dependent on details 
that can easily change (specifically, whether the default `NoteName` text is a 
markup that `markup->string` works well on). That's why I recommend 
`noteNameFunction` instead, it's also simpler.

There's may be one extra paren in there because it threw a syntax
error.  I removed one paren and it seems to work:

germanNoteNames =
#(lambda (grob)
   (let* ((default-name (markup->string (ly:grob-property grob 'text)))
  (new-name (assoc-get default-name newnames)))
 (ly:grob-set-property! grob 'text new-name)
   (ly:text-interface::print grob)))

Tested on the mwe I made earlier today.

Is that a proper fix, or is something else wrong?

Re: Changes to Notename - lost some functionality

[Jean Abou Samra]

This code is too big for me to digest it, but the basic problem is that 

```
   (let* ((default-name (ly:grob-property grob 'text))
  (new-name (assoc-get default-name newnames)))
```

is doing a lookup in your `newnames` alist with the value of `text` as the key. 
In more recent versions, `text` is not a string but a full markup, which you 
can see if you add `(display default-name)`. So the lookup fails, `assoc-get` 
returns false (`#f`), and you set the grob's text to false, which leads to a 
warning because false isn't a markup.

The quick fix here is to change

```
(let* ((default-name (ly:grob-property grob 'text)))
```

to

```
(let* ((default-name (markup->string (ly:grob-property grob 'text
```

in order to first get an approximate string representation of that markup that 
corresponds to the keys in your alist.

But instead of this fragile method of changing note names, it would be a lot 
better to write a custom `noteNameFunction`, e.g.,

```
\version "2.24.2"

\new NoteNames {
  \set noteNameFunction =
#(lambda (pitch context)
   ;; Write logic to compute the note name from `pitch` as a markup.
   "TODO")
  c' d' e'
}
```

Re: Hide a note inside a drumscore

[Sebastien Richard]

Thanks for your reply

I tried your exemple with the tie which also work great

In the full drumscore the tie gets "pushed" down. I'm trying to figure out a 
way to reposition it but I can't get any command to do so (tried "\tweak 
positions" and "\override Tie.positions")

Any ideas ?

You are thinking too complicated.

up = \drummode {
  \slurDown \grace {sn16 sn(} 4
}
\score {
  \new DrumStaff
  << \new DrumVoice { \voiceOne \up } >>

But I consider it very likely that you actually don't want a slur but a

Continuation slur and key signature with many sharps

[Knute Snortum]

Hi List,

Here is something that pops up now and then when I'm engraving with
LilyPond: if a key signature has a lot of sharps, like the key of e major,
sometimes a continuation slur will be too close to the key signature.  Here
is a snippet:

%%%
\version "2.25.11"

\paper {
  ragged-right = ##t
}

\relative {
  \key e \major % ugly
  % b major is okay
  % f sharp major is ugly too
  cis''1( | \break
  cis1) |
}
%%%

The output is attached.  What is your opinion on this?  Is it an "ugly"
issue or not a problem?

Thank you for your reply!

The results of that snippet are easily accomplished with simple code and 
simple code is what I am using as a substitute for what I was trying to 
get.  For example:


s1\> s1_\markup\italic{molto} s2. s8\!

I actually was trying to get "molto" inside the hairpin.

The issue you are running into is that overrides won't work on a single item 
when there's more than one of them happening at the same moment in the music. 
As these are (basically) notes within a chord, they're at the same moment. And 
the \hide command is just a shortcut for an override on the grob's Transparent 
property. In the case of simultaneous grobs, you want the \tweak command. 
http://lilypond.org/doc/v2.25/Documentation/notation/tweak-and-single

So, your code would become:

\version "2.24.2"

up = \drummode {
  \slurDown \grace { sn16 sn( }  4
}

\score {
  \new DrumStaff <<
\new DrumVoice {

Changes to Notename - lost some functionality

[Sebastian Käppler]

Dear lilypond experts,

I seem to have missed some changes to LilyPond between 2.19.82 and current
versions. I use a quite big script to automatically generate some music
theory tasks for my students (in German). I'll post the complete example
below. However, my code for creating note names doesn't work anymore. The
line printed bold probably is causing problems:
\context NoteNames \with {
%%% Show notenames only for reading tasks
   * \override NoteName.stencil = #(if (and (not solution) (equal? mode
#\r)) blankNoteNames germanNoteNames)*
\override NoteName.Y-offset = -2
\override NoteName.X-offset = -1
  }

germanNoteNames is:
germanNoteNames =
#(lambda (grob)
   (let* ((default-name (ly:grob-property grob 'text))
  (new-name (assoc-get default-name newnames)))
 (ly:grob-set-property! grob 'text new-name)
   (ly:text-interface::print grob)))

I can run this code, but get "Trying to interpret a non-markup object: #f". The
blanks (or note names) are printed, but I don't get actual note names.

Any help on this would be appreciated, I'm a bit lost now where to start.
I've attached the current version of my script below, with example code at
the end of the file. My last working version and it's "documentation" can
be found at
https://gist.github.com/TheNothingMan/6f5daf540d55b4ad9138e3ff5d3ffbd0

Thank you very much for any help!
