Hello Richard,
I just discovered your explanation is in fact the case, and also
concluded cond wouldn't work either.
I might have to settle for an empty markup block for now.
The point of interpret-markup is to turn a markup into a stencil, so I'd
use empty-stencil:
\version "2.20.0"
#(define-markup-command (print-if-defined layout props sym text)
(symbol? markup?)
(if (defined? sym)
(interpret-markup layout props
#{ \markup \with-color #'(0.8 0.2 0.2) #text #})
empty-stencil))
symA = "Something"
\markup {
\print-if-defined #'symA "Text"
\print-if-defined #'symB "More text"
}
Best,
Jean
