Re: markup to render music on left, show code on right) without typing music twice

[Sam Speer]

Are you willing to use include files? Here's a way to do it in pure LP:

\version "2.24.4"
\markup {
  \justify-line {
    " "
    \score { \include "incl.ly" }
    \combine \arrow-head #X #LEFT ##f \draw-line #'(3 . 0)
    \verbatim-file "incl.ly"
    " "
  }
}
