So, in partial answer to my own question, we can achieve control over line
cap style using a markup context, and the following code works fine:
(if is-rest?
empty-stencil
(ly:stencil-add
stil
(grob-interpret-markup grob
(markup
#:override (cons (quote line-cap-style) (quote square))
(#:path
0.2
(list (list (quote moveto) start-x start-y)
(list (quote lineto) end-x end-y)))))))
However, I am still interested in the answer to my original question, if
that is possible at all?

Subject: Line cap style in scheme
I'm writing a function to make horizontal slashes through note stems.
The function make-line-stencil uses round end caps, but I prefer square or
butt style. I have asked this question before on the list, but the pointers
to possible answers referred to code for making markups, which is good,
whereas I want to set the end cap style for a path stencil.
Here's a fragment of the code in question (not meant to be a MWE, just to
give the programming context):
(if is-rest?
empty-stencil
(ly:stencil-add
stil
(make-path-stencil
(list
'moveto start-x start-y
'lineto end-x end-y)
thickness 1 1 #t)
))
Is it possible to inject calls here to set the postscript line cap style?
Andrew
