Re: How to change coda mark symbol in \repeat segno structure?

[Jean Abou Samra]

This should do the trick:

\version "2.24.2"

{
  \repeat segno 2 {
c'1
\alternative {
  \volta 1 {
\once \set Score.codaMarkFormatter =
  #(lambda args
 #{ \markup "foo bar" #})
c'1
  }
  \volta 2 \volta #'() { \section \sectionLabel Coda }
}
  }
  c'1
}

How to change coda mark symbol in \repeat segno structure?

[Vlado Ilić]

Hello,

I'm trying to change coda symbol that appears when using  \repeat segno
structure.If i understand correctly, Mark_engraver is responsible for it
and Layout Object is CodaMark.
I've tried setting \override CodaMark.text = \markup {"test"} in Voice,
Staff and Score context but nothing changes.
What am I missing?

Re: strange detached beam issue

[Jin Choi]

Thanks, you were right. There was an unterminated Slur.outside-staff-priority 
override that was causing the problem. This snippet displays the flying beam:

\version "2.24.1"

top = { \change Staff = "upper" \voiceTwo }
bottom = { \change Staff = "lower" \voiceOne }

upper = \relative c'' {
  \override Slur.outside-staff-priority = #300
  
 \time 2/2
 \key c \major
 \voiceOne
 r8 bes'\mf( a gis a ees d cis |
 d bes a gis a ees d cis |
 d) bes'\dim( a\! gis a ees d cis |
 d[ \bottom bes a gis] a[ ees d)] r8 |
 \top 
 \oneVoice
 r8\p
}

lower = \relative c' {
 \clef bass
 a4 r8 \top bes'( a gis a ees |
 d cis d \bottom \voiceTwo bes a gis a ees |
 d cis d bes' a gis a ees |
 d cis d bes a gis a cis | 
 \oneVoice
 fis,4)

}

\score {
 \layout {
   \context {
 \Staff
 \consists Merge_rests_engraver
   }
   \context {
 \PianoStaff
 \override StaffGrouper.staff-staff-spacing.basic-distance = #11
 \override TextScript.avoid-slur = #'outside
 \override TupletBracket.bracket-visibility = ##f
   }
 }  
 \new PianoStaff {
   <<
   \new Staff = "upper" \upper
   \new Staff = "lower" \lower
   >>
 }
}

The reason it was removed is that the feature has been added to LilyPond itself.
Use \vshape instead of \shape to see the control points, then remove the "v".

Re: s-curve slurs across staves?

[Jin Choi]

It was “Adjusting slurs and ties in LilyPond”, from this group’s archives:
https://lists.gnu.org/archive/html/lilypond-user/2019-10/pdfn4OnsjHZAm.pdf

Some of the features look very handy to describe control points as polar 
coordinates, but I don’t want to drop in a whole mass of code just for that.

I did find a snippet (also from this group’s archives) for displaying the 
actual control points, which helped immensely with tweaking Lukas’s example, 
and also discussion of being able to do it in Frescobaldi under Layout Control 
Mode, which appears to have moved to Tools/Viewers/Layout Control Options but 
now has no option for displaying control points.

arranger.ly with lilypond 2.25 : intlog2 fatal error

[Raphael HARDY]

‌Hello!
I'm regularly using the arranger.ly library to make scores for children 
orchestras
When trying to use it with lilypond v2.25, I sometimes get
fatal error: intlog2 with negative argument: 0

For example using this small code that works as expected on 2.24 and triggers 
the fatal error on 2.25

\version "2.25.7"
%\version "2.24.2"
\include "arranger.ly"
\language "english"

global = { s1 * 4 } % get a 4 bars score

all = #'( flute ) % add instrument(s)

#(begin
  (init all)
  (fill 'flute #{ c''4 #} 1 5 ) ; fill 4 bars with quarter notes
  (rm 'flute '(3 -4) #{ r4 #} ) ; insert a rest one beat before bar 3
  )

\flute

%%

I can see where arranger.ly uses ly:intlog2 but I don't understand the error. 
Any idea on what could be the cause?

Two reasons:

- I wasn't aware that figures support " " without a \markup
- To me, <_/> and in particular  feel closer to having semantic input.

But thanks, in particular for the nice design using \beam! :-)

The slash is pronounced the best of several possibilites by
C. Ph. E. Bach [...]

Thanks.  Please open an issue for SMuFL at

   https://github.com/w3c/smufl/issues

so that this slash symbol gets added to the figured bass glyphs.

Obviously, you can customize it with


\version "2.25.7"

slashMarkup =
\markup
\beam #0.5 #2.0 #0.3

\layout {
  \override Score.BassFigure.stencil =
  #(grob-transformer
'stencil
(lambda (grob orig)
  (if (equal? "/" (ly:grob-property grob 'text))
  (grob-interpret-markup grob slashMarkup)
  orig)))
}

<<
   \new FiguredBass \figuremode {
 <"/"> <6> <"/"> <6>
   }
   \new Staff \with { \clef bass } {
 f4 e d c
   }

Hi,

I'm Jurgen, volunteering for Software Freedom Day 
. Some friends at the FSF recommended me 
to reach out to your team with this:


For Software Freedom Day (Sept. 16th), the team Software Freedom Day 
team creating the best Software Freedom Song, can win a nice prize 
donated by MuseScore.


I think it would be cool if someone using Lilypond would create a song 
about Software Freedom!


You can find more details here: 
https://www.digitalfreedomfoundation.org/index.php/171-software-freedom-day-music-challenge


You can join us to chat on Matrix 
 if you have more 
questions.


Hope to be hearing from you!

All the best,
