By commenting things out, I identified the following as the first line that
causes the error:
(stem-stil (ly:grob-property stem 'stencil))
So it seems like the stem grob's stencil may not have been created yet, at the
point where we are trying to get its width?
I tried the following, which moves the attempt to access the stencil behind the
"ly:stencil?" check, but it returned the same error anyway.
(stem (ly:grob-object grob 'stem))
(stem-thick (ly:grob-property stem 'thickness 1.3))
;; (stem-stil (ly:grob-property stem 'stencil))
(stem-x-width (if (ly:stencil? (ly:grob-property stem 'stencil))
(interval-length (ly:stencil-extent (ly:grob-property stem
'stencil) X))
;; if no stem-stencil use 'thickness-property
(/ stem-thick 10)))
(stem-dir (ly:grob-property stem 'direction))
;; Calculate a value to compensate the stem-extension
(stem-x-corr
(map
(lambda (q)
(+ 1 1)
)
nh-duration-log)))
