Hi all,


\version "2.21"
{ \omit Script c''1^\fermata_\espressivo }

obviously both Script grobs will be omitted; same, of course, with

\version "2.21"
\layout { \context { \Score \omit Script } }
{ c''1^\fermata_\espressivo }

Is there a way (e.g., via callback or improved \omit function definition) to make \omit more surgical? For example, can one effectively say

     \omit #'(fermata) Script

so that only fermatas get omitted?

Perhaps something like:

Or, with a little bit more sugar:

\version "2.22"

omitScriptTypes =
#(define-music-function (types) (symbol-list?)
      (lambda (grob)
        (if (memq
              (ly:event-property (ly:grob-property grob 'cause)
      \override Script.stencil = #stencil

example = { a'4\fermata a'\tenuto a'\espressivo a'\marcato }

  \omitScriptTypes fermata
  \omitScriptTypes fermata, tenuto
  \omitScriptTypes tenuto, espressivo, marcato
  \omitScriptTypes #'()

(I'm a bit surprised that the articulation type is stored in a string instead of a symbol; maybe there's another property that I'm overlooking, as my call to string->symbol isn't really what you would call elegant.)
