Hello,
I wonder if it is possible to return markup AND score from a single
scheme
function, something like this:
example = #(define-scheme-function (parser location) ()
#{
\markup "Test"
\score {
c'4
}
#}
)
I created some scripts for teaching and want to include task-markup
before
each score. Using markup and my functions outside of scheme works, but
I
couldn't get it to work from a single function.
Seems to be that the parser cannot figure out what is meant by #{
\markup ... \score ... #} even though both of those items are permitted
to appear at the top-level. With #{ \markup ... #} or #{ \score ... #},
the parser appears to do the right thing.
While there is probably some clever trick that permits #{ \markup ...
\score ... #} to parse correctly, I am not seeing it. So, here are two
potential options: either nest the score within the markup or vice
versa:
%%%%
\version "2.19.82"
\markup "Hello, World!" \score { { a'4 b' g'2 } }
scoreInsideMarkup =
#(define-scheme-function (label notes) (string? ly:music?)
#{ \markup { \column { $label \score { $notes } } } #})
markupInsideScore =
#(define-scheme-function (label notes) (string? ly:music?)
#{ \score { { \tweak X-offset #(/ -15 1.7573)
\mark \markup \fontsize #-2 $label $notes } } #})
\scoreInsideMarkup "Hello, World!" { a'4 b' g'2 }
\markupInsideScore "Hello, World!" { a'4 b' g'2 }
%%%%
Note that when using a RehearsalMark, a suitable adjustment to the
alignment and font size is needed to match the appearance of the other
two.
