Hello,
I’m trying to calculate the width of a InstrumentName markup to
automatically
set the indent. Some time ago I somewhat managed to do an
interpretMarkup by
looking up layout and parser, but I cannot remember, how I did it.
So maybe someone of you guys has a decent way of doing this?
This seems to work:
%%%%
\version "2.20.0"
measureMarkup =
#(define-scheme-function
(axis text)
((number? X) markup?)
(let* ((layout (ly:parser-lookup '$defaultpaper))
(props (ly:output-def-lookup layout 'text-font-defaults))
(sten (interpret-markup layout (list props) text)))
(* (interval-length (ly:stencil-extent sten axis))
(ly:output-def-lookup layout 'staff-space))))
foo = \markup \box \pad-x #2 \italic "Lorem ipsum"
\paper { indent = \measureMarkup \foo }
\new Staff \with { instrumentName = \foo }
{ \repeat unfold 16 { b'4 4 2 } \bar "|." }
%%%%
