Thanks Jan.
So I revised my code, and now it works. For the sake of somebody else
who might someday struggle with a similar thin,
Here's a working code fragment.
#(def-markup-command (markup-dot paper props radius) (number?)
"Syntax: \\markup-dot dot-radius
eg: \\markup-dot #0.25 for dot with 1/2 staff space diameter"
(ly:make-stencil (list 'dot 0 3 radius) (cons radius radius) (cons
radius radius) )
)
\score {
\notes {
c''2.^\markup \markup-dot #0.5
}
}
Thanks for your help. I think now I can put together a simple chord
diagram -- we'll see!
Carl

A good effort with an understandable mistake. You cannot use (dot )
directly, the interface functions in output-*.scm are output commands
for `Stencil's with that name.
So, you'll have to make a 'dot' stencil. How to do that? Use
ly:make-stencil. See, eg, scm/stencil.scm:
(define-public (make-filled-box-stencil xext yext)
"Make a filled box."
..)
Good luck,
Jan.
