RE: Help on markups

[Carl D. Sorensen]

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.
