Hey!
Total hack, but if you check out scm/stencil.scm, you’ll see how parentheses
are made…
(define-public (parenthesize-stencil
stencil half-thickness width angularity padding)
"Add parentheses around @var{stencil}, returning a new stencil."
(let* ((y-extent (ly:stencil-extent stencil Y))
(lp (make-parenthesis-stencil
y-extent half-thickness (- width) angularity))
(rp (make-parenthesis-stencil
y-extent half-thickness width angularity)))
(set! stencil (ly:stencil-combine-at-edge stencil X LEFT lp padding))
(set! stencil (ly:stencil-combine-at-edge stencil X RIGHT rp padding))
stencil))
So it looks like you can substitute in make-connected-path-stencil for
make-parenthesis-stencil, using sensible parameters for the connected path
based on the y extent and the width.

Hi all,
I don't seem to find the right thing, neither in the docs, the LSR nor
the list archive. I need to put square brackets around some accidentals
in order to differentiate them from default parentheses.
I don't find the way to create the respective stencil for this.
It has to be possible to do that \once, and I assume I'll run into the
situation where I will need both round and square ones within a chord.
Any help available?
Thanks
Urs
