Hi Paolo,
this function was the example of my talk at the Music Engraving
Conference in Salzburg this January.
While preparing the talk I cured some glitches in the original
function above. Reworked code below.
Though, the visual outcome is bad for scaling values > 2, because the
"tip" of the arrow-head, meant to join the arpeggio-element, becomes
too large and sticks out.
Would be better to create a new arrow-head, via markup-command or else.
In any case, it looks strange to have a very huge arrow-head sitting
on a default-sized trill-like arpeggio-line, imho.
Anyway, here the Salzburg-code:
scaleArpeggioArrow =
#(define-music-function (scale)(number?)
#{
\override Arpeggio.stencil =
#(lambda (grob)
(let ((arp-dir (ly:grob-property grob 'arpeggio-direction)))
(if (null? arp-dir)
(ly:arpeggio::print grob)
(let* ((arrow-glyph
(format #f
"scripts.arpeggio.arrow.~a1"
(if (negative? arp-dir)

Hello Neyzenemre, Catalina requires the 64 bit version, and 2.20.0 64 runs fine here. Maybe you installed the 32 bit version?

I'm not aware of an automated way.
On the other hand, I find that it is not really much trouble to just reset
the bar numbers as you need to. You're already writing code for \repeat
volta and \alternative and possibly \bar "||" and so forth, so what is one
additional line of code to reset the bar number?

So, here is a function I use to show duplicate bar numbers.
You pass in the starting bar number, and the number of repeated bars.
Also, the ones I use for triple and quadruple numbers.
Usage:
\set Score.currentBarNumber = #42
\set Score.barNumberFormatter = #(double-bar-number 16)
#(define (double-bar-number increase-amount)
(lambda (barnum measure-pos alt-number context)
#{
\markup
\override #'(baseline-skip . 2)
\center-column {
#(robust-bar-number-function barnum measure-pos
alt-number context)
#(robust-bar-number-function
(+ increase-amount barnum) measure-pos alt-number
context)
}
#}
)
)
#(define (triple-bar-number increase-amount)
(lambda (barnum measure-pos alt-number context)
#{
\markup
\override #'(baseline-skip . 2)
\center-column {
#(robust-bar-number-function barnum measure-pos
alt-number context)
#(robust-bar-number-function
(+ increase-amount barnum) measure-pos alt-number
context)
#(robust-bar-number-function
(+ increase-amount (+ increase-amount barnum))
measure-pos alt-number context)
}
#}
)
)
#(define (triple-bar-number-plus-offset increase-amount offset-amount)
(lambda (barnum measure-pos alt-number context)
#{
\markup
\override #'(baseline-skip . 2)
\center-column {
#(robust-bar-number-function barnum measure-pos
alt-number context)
#(robust-bar-number-function
(+ increase-amount barnum) measure-pos alt-number
context)
#(robust-bar-number-function
(+ increase-amount (+ increase-amount (+ barnum
offset-amount))) measure-pos alt-number context)
}
#}
)
)
#(define (quadruple-bar-number increase-amount)
(lambda (barnum measure-pos alt-number context)
#{
\markup \override #'(baseline-skip . 2)
{
\center-column {
#(robust-bar-number-function barnum measure-pos

#(robust-bar-number-function

}
\center-column {

Equal space between all notes
Please, I cannot find a way to set the same horizontal space between different notes. For example, i would like to have the identical horizontal space between 2/4 notes and 1/4... A greater duration usually takes more space, while I need always the same... Thanks! -- Sent from: http://lilypond.1069038.n5.nabble.com/User-f3.html

Re: Default accidental style with timing off
After some more work I came up with the attached redefinition of the bar which does what I originally asked for.

Re: Equal space between all notes
Does a combination of proportionalNotationDuration and overriding the SpacingSpanner do the trick? The attached example, admittedly a bit of a hack, seems to work. spacing-mwe.ly Description: Binary data
Break visibility for notes?
Is there a way to specify that a note should only appear if it’s the first note
on the line? I tried using the break-visibility property but this doesn’t seem
to be working (the notes simply disappear entirely.
\version "2.19.84"
mystart = \override Voice.NoteHead.break-visibility = #begin-of-line-visible
myend = \revert Voice.NoteHead.break-visibility
music = { \repeat unfold 20 { c' } \mystart g' g' g' g' g' g' g' g' \myend
\repeat unfold 20 { c' } }
\new Staff {
\new Voice = "mel" { \music }
}

Seems fine.
A pattern I could recommend is defining a named procedure as opposed to
using a lambda with \applyContext:
foo = #(define-music-function () ()
(define (proc context)
(do-something-here))
#{ \applyContext #proc #})
This keeps potentially complex S-expressions outside LilyPond syntax,
which should improve readability.
Apart from that, I would suggest simplifying your variable names. There
is no need to call something "mything" when "thing" would suffice.
Remember that bindings have scope; and local bindings trump. You only
need unique names if you must have access to both variables.
That said, I would prefer "my-thing" over "mything". You have to be
careful with smooshing words together lest they read poorly. "curnum"
is not ideal as it looks like it could be a word in Latin. "currnum" is
slightly better, but "curr-num" would be the preference if abbreviation
is required.
Mind you, I would sidestep all that by calling it "bar-number":
(let* ((score (ly:context-find context 'Score))
(bar-number (ly:context-property score 'internalBarNumber)))
(ly:context-set-property! score 'internalBarNumber (1+ bar-number)))
