Re: Absolute font-size for TextScript

[Kieren MacMillan]

Hi Paolo,

> is it possible to set an absolute font-size for *all* the TextScript objects?

I use this (from an include file):

%%%%
allowGrobCallback =
#(define-scheme-function (parser location syms) (symbol-list?)
   (let ((interface (car syms))
         (sym (cadr syms)))
     #{
       \with {
         \consists #(lambda (context)
                      `((acknowledgers .
                          ((,interface . ,(lambda (engraver grob 
source-engraver)
                                            (let ((prop (ly:grob-property grob 
sym)))
                                              (if (procedure? prop) 
(ly:grob-set-property! grob sym (prop grob)))
                                              ))))
                          ))
                      )
       }
     #}))

absFontSize =
#(define-scheme-function (parser location pt)(number?)
   (lambda (grob)
     (let* ((layout (ly:grob-layout grob))
            (ref-size (ly:output-def-lookup (ly:grob-layout grob) 
'text-font-size 12)))
       (magnification->font-size (/ pt ref-size))
       )))

\layout {
  \context {
    \Score
    \allowGrobCallback font-interface.font-size
  }
}
%%%%

> if this has already been implemented as a built-in feature

No… but I would love to see it (or something "better"?) added to the base 
distro.

Hope that helps!
Kieren.
