Mensurstriche layout (bar lines between the staves)

Mensurstriche, bar lines between but not through staves, can be printed by setting measureBarType to "-span|" and using a grouping context that allows span bars, such as StaffGroup.

\version "2.24"

\layout {
  \context {
    \Staff
    measureBarType = "-span|"
  }
}

music = \fixed c'' {
  c1
  d2 \section e2
  f1 \fine
}

\new StaffGroup <<
  \new Staff \music
  \new Staff \music
>>
