RE: TextScript extra-offset in Scheme

[Mike Solomon]

Not in front of my computer, but off the top of my head, there are staff -padding and use - skyline properties for the text script. You can play around with making these ##f in addition to outside staff priority and see if that helps get you closer to what you're after.

Subject: TextScript extra-offset in Scheme

Greetings Ponderers,

I am doing some work with some custom slur drawing for grace notes, for various (way too complicated to explain here) reasons. I need to position these graphic marks very precisely, and very close to the notehead. I am using Scheme functions to draw my paths, and producing a markup function to use in the music. The issue I am having is that for each mark, and I have hundreds, I need to adjust the TextScript offset to get them positioned for a good appearance, using

\once \override TextScript.extra-offset = #’(0 . -5)

for example.

What I am asking is how to adjust the TextScript.extra-offset inside define-markup-command code. I have simplified the code to the bare minimum, so it is somewhat artificial, but hopefully it is clear what I am attempting. How can I have complete control over the positioning to the offset of the line in this example? I can’t get it to cross into the staff lines, even when I globally set outside-staff-priority to ##f. Translating the stencil in the Scheme does not seem to be adequate.

\version "2.19.24"

#(define-markup-command (graphic layout props dest offset)

   (pair? pair?)

   (let* ((stil

           (interpret-markup layout props

             (markup #:draw-line dest))))

     (ly:stencil-translate stil offset)))

treble = \relative c'' {

  \clef treble

  \time 1/4

  c

  \grace {

    \stemDown

    %\override TextScript.outside-staff-priority = ##f

    bes8^\markup \graphic #'(2 . 2) #'(0 . -3)

  }

  bes4 a c

}

\score {

  \new Staff { \treble }

  \layout { }

}
