Thank. well that got me a step farther. However now I see that this works
without curly braces around the \markup...Examples below. I'm not that
familiar with guile so it's probably related to how variables work in
guile. The end goal is to have a fair amount of template stuff in the
function with some variables passed in to fill in some gaps.
\version "2.24.4"
hdr =
#(define-scheme-function (name) (string?)
#{
\header {
title = \markup #name
}
#})
\hdr "test"
%\header { title = test }
\score {
{c4 d e f}
}
This throws an error.
hdr =
#(define-scheme-function (name) (string?)
#{
\header {
title = \markup {#name}
}
#})
\hdr "test"
%\header { title = test }
\score {
{c4 d e f}
}
Guile signaled an error for the expression beginning here
title = \markup {#
name}
Unbound variable: #{name\x7d;}#
