[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] #5047 markLeng

status: New --> Accepted
Comment:

Some observations:

This happens for some other spanners as well, if they are bounded by spacers not at the same moment as the NoteColumns.
Replacing the spacer with rests work
It fails for MetronomeMark, but not for RehearsalMark!

Test code:

\version "2.19.52"

\paper { indent = 30 }

\markup \rounded-box "Test with spacers: \\markLengthOn fails"

$@(map
   (lambda (mus mrkp)
   #{
      \new Staff \with { instrumentName = #mrkp }
        << 
          { \markLengthOn \tempo "MetronomeMark" c''1 \tempo "next one" d''1 }  
          { s4 #mus s1 } 
        >>
   #})
   (list
     #{ s2\< s4\! #}
     #{ s2\startTextSpan s4\stopTextSpan #}
     #{ s2\startTrillSpan s4\stopTrillSpan #}
     #{ s2( s4) #}
     #{ s2~ s4 #}
     #{ \[s2 s4\] #})
   '("Hairpin" "TextSpanner" "TrillSpanner" "Slur" "Tie" "LigatureBracket"))

\markup \rounded-box "Same with (omitted) Rests: \\markLengthOn works"

$@(map
   (lambda (mus mrkp)
   #{
      \new Staff \with { instrumentName = #mrkp }
        << 
          { \markLengthOn \tempo "MetronomeMark" c''1 \tempo "next one" d''1 }  
          { s4 \omit Rest #mus s1 } 
        >>
   #})
   (list
     #{ r2\< r4\! #}
     #{ r2\startTextSpan r4\stopTextSpan #}
     #{ r2\startTrillSpan r4\stopTrillSpan #}
     #{ r2( r4) #}
     #{ r2~ r4 #}
     #{ \[r2 r4\] #})
   '("Hairpin" "TextSpanner" "TrillSpanner" "Slur" "Tie" "LigatureBracket"))

\markup \rounded-box "Same with spacers and \\mark: \\markLengthOn works"

$@(map
   (lambda (mus mrkp)
   #{
      \new Staff \with { instrumentName = #mrkp }
        << 
          { 
            \override Score.RehearsalMark.self-alignment-X = #LEFT
            \markLengthOn 
            \mark "RehearsalMark" c''1 \mark "next one" d''1 
          }  
          { s4 #mus s1 } 
        >>
   #})
   (list
     #{ s2\< s4\! #}
     #{ s2\startTextSpan s4\stopTextSpan #}
     #{ s2\startTrillSpan s4\stopTrillSpan #}
     #{ s2( s4) #}
     #{ s2~ s4 #}
     #{ \[s2 s4\] #})
   '("Hairpin" "TextSpanner" "TrillSpanner" "Slur" "Tie" "LigatureBracket"))

Dave Hartley reports here:

about \markLengthOn sometimes failing, if a second voice carries a Hairpin.

Minimal example:

\version "2.19.52"

\new Staff
  << 
    { \markLengthOn \tempo "MetronomeMark" c''1 \tempo "next one" d''1 } 
    { s4 s2\< s4\!  s1 }
