Re: possible bug?

Hi Erik,

Just showing one other bar that looks suddenly awfull with strict spacing

<<

\new Staff \relative c'' {

es4-- r8

  \tuplet 5/4 {f32([ ges as ges f)]}

  es8^.[ \acciaccatura {a} bes^!] es,4-- |

}

Thanks, that really is not desirable.

The \newSpacingSection command also introducing no problems, I see no good solution with current LilyPond.

The problem is that the setting to treat grace columns as loose (strict-grace-spacing) is fixed for the spacing spanner. It's almost trivial to add an \override'able setting to PaperColumns in general, but this requires re-compiling LilyPond. With a new property Score.PaperColumn.force-loose-grace-spacing, I can achieve

with

\version "2.23.6"

<<
  \new Staff \relative c'' {
    \override Score.PaperColumn.force-loose-grace-spacing = ##t
    g8[ b16 as] g8[ b] a16[ g b a] g8[ \appoggiatura { g32 a } b8]|
    \revert Score.PaperColumn.force-loose-grace-spacing
    es4-- r8 \tuplet 5/4 {f32([ ges as ges f)]} es8^.[ \acciaccatura { a } bes^!] es,4-- |
  }
  \new Staff \relative c'' {
    g8[ b16 as] g8[ b] a16[ g b a] e16[ d f e]
  }

You don't need to try compiling this with your version of LilyPond, as it won't work. But this should be discussed on the developers list; I'll try to take care of this tomorrow.
