My apologies. I made another change in the dashed-path markup command
that mattered. Here's the complete code for reference:
%%%%
\version "2.22.0"
#(define* (dashed-path-ps thickness on off phase exps
#:optional (cap 'round) (join 'round))
(let* ((path (module-ref (resolve-module '(scm output-ps)) 'path #f))
(ps (path thickness exps cap join))
(lines (string-split ps #\nl)))
(set! lines (cons (car lines)
(cons (ly:format "[ ~4f ~4f ] ~4f setdash" on off phase)
(cdr lines))))
(string-join lines "\n")))
#(let* ((module (resolve-module '(scm output-ps)))
(alist (module-ref module 'stencil-dispatch-alist '())))
(module-define! module 'stencil-dispatch-alist
(acons 'dashed-path dashed-path-ps alist)))
#(ly:register-stencil-expression 'dashed-path)
#(define-markup-command
(dashed-path layout props thickness commands)
(number? list?)
#:category graphic
#:properties ((line-cap-style 'round)
(line-join-style 'round)
(on 1) (off 1) (phase 0))
(let ((sten (path-markup layout props thickness commands))
(command-list (fold-right append '() commands)))
(ly:make-stencil
`(dashed-path ,thickness ,on ,off ,phase
,command-list ,line-cap-style ,line-join-style)
(ly:stencil-extent sten X)
(ly:stencil-extent sten Y))))
samplePath =
#'((moveto 0 0)
(lineto -1 1)
(lineto 1 1)
(lineto 1 -1)
(curveto -5 -5 -5 5 -1 0)
(closepath))
\markup \path #0.25 #samplePath
