Subject: rests in chord symbols with volta endings
Hi,

I was trying to use https://lsr.di.unimi.it/LSR/Snippet?id=529
to add some rests to chord symbols

After using convert-ly it worked as is.

However, when using this in the context of repeat voltas,
chords in the endings appear above the ending lines,
rather than below as normal.

Does anyone have any suggestions for how to get the chord symbols below the ending lines?

\version "2.22.0"

\layout {
\context {
\type "Engraver_group"
\name ChordNamesRests
\description "Typesets chord names."

\consists "Output_property_engraver"
\consists "Separating_line_group_engraver"
\consists Chord_name_engraver \consists Current_chord_text_engraver

\consists "Rest_engraver"

noChordSymbol = ##f

\override VerticalAxisGroup.staff-staff-spacing = #'((padding . 1))
\override VerticalAxisGroup.remove-first = ##t
\override VerticalAxisGroup.remove-empty = ##t
}

\context {
\Score
\accepts ChordNamesRests
}
}

music = {
c4 d e d
f4 r g r
c,1
}

structure = {
\repeat volta 2 {
s1
}
\alternative {
{ s1 }
{ s1 }
}
}
\score {
<<
\new ChordNamesRests {
\chordmode {
\override Rest.Y-offset = #1
\music
}
}
\relative c' <<
\structure
\music
>>
>>
}

Thanks,

Elaine Alt

Well, the snippet neither adds Axis_group_engraver to ChordNamesRests, nor makes it child of some context with Axis_group_engraver like Staff. As a result, the chord name grobs are at the level of the whole system, like other system-level grobs such as volta brackets or rehearsal marks. Actually, they are more “system-level” than those, because grobs like volta brackets are moved inside the top staff after line breaking.

I don't understand why the snippet has these VerticalAxisGroup overrides. They have no effect, since there is no VerticalAxisGroup in the context.

Try
\version "2.24.1"

\layout {
  \context {
    \type Engraver_group
    \name ChordNamesRests
    \description "Typesets chord names."

    \consists Output_property_engraver
    \consists Separating_line_group_engraver
    \consists Chord_name_engraver
    \consists Current_chord_text_engraver
    \consists Rest_engraver
    noChordSymbol = ##f
    \consists Axis_group_engraver
    \override VerticalAxisGroup.staff-affinity = #DOWN
    \override VerticalAxisGroup.remove-first = ##t
    \override VerticalAxisGroup.remove-empty = ##t
  }
  \context {
    \Score
    \accepts ChordNamesRests
  }
}

music = {
  c4 d e d
  f4 r g r
  c,1
}

structure = {
    \repeat volta 2 { 
        s1
    }
    \alternative {
        { s1 }
        { s1 }
    }
}
\score {
  <<
    \new ChordNamesRests {
      \chordmode {
        \override Rest.Y-offset = #1
        \music
      }
    }
    \relative c' <<
        \structure
        \music
    >>
>>
}
Regards,

Jean

By the way: regarding the above, I invite you to read the thread

https://lists.gnu.org/archive/html/lilypond-user/2022-11/msg00199.html

Thanks for the help.

I forgot to mention that am still on 2.22, so I am still using the traditional syntax of \repeat and \alternative

It appears that this is actually the MWE, at least for 2.22

all the other lines I removed did not affect either this MWE or my actual real world score.

\version "2.22.0"

\layout {
\context {
\type Engraver_group
\name ChordNamesRests
\consists Chord_name_engraver
\consists Rest_engraver
noChordSymbol = ##f
\consists Axis_group_engraver
}
\context {
\Score
\accepts ChordNamesRests
}
}

myMusic = \relative c'' {
c4 d e d
f4 r g r
c,1
}
myChords = \chordmode {
\override Rest.Y-offset = #1
c4 d e d
f4 r g r
c,1
}

structure = {
\repeat volta 2 {
s1
}
\alternative {
{ s1 }
{ s1 }
}
}

\score {
<<
\new ChordNamesRests \transpose c c {
\myChords
}
\new Staff <<
\structure
\myMusic
>>
>>
}

Thanks,

Elaine Alt
