Re: again: funktionsbezeichnung

[Mats Bengtsson]

Here's an alternative solution that defines a markup command to add the 
slash
to any character.

\version "2.10.0"
% Inspired by slashed-digit from scm/define-markup.scm:
#(define-markup-command (slashed-char layout props ch) (char?)
 "A character, with slash."
 (let*
     ((mag (magstep (chain-assoc-get 'font-size props 0)))
      (thickness
   (* mag
      (ly:output-def-lookup layout 'line-thickness)
      (chain-assoc-get 'thickness props 1.6)))
      (char-stencil (interpret-markup layout props ch))
      (num-x (interval-widen (ly:stencil-extent char-stencil X)
                 (* mag 0.1)))
      (num-y (ly:stencil-extent char-stencil Y))
      (is-sane (and (interval-sane? num-x) (interval-sane? num-y)))
     
      (slash-stencil
   (if is-sane
       (ly:make-stencil
        `(draw-line
          ,thickness
          ,(car num-x) ,(car num-y)
          ,(cdr num-x) ,(cdr num-y))
        num-x num-y)
       #f)))
   (ly:stencil-add char-stencil slash-stencil)))


\relative c'{ < b d f >1^\markup {  \slashed-char #"D" \super 7 } }
