what must I write to shorten an unbeamed stem by, say, one unit?
A naive approach would be
\once \override Stem.length #(- ly:stem::calc-length 1)
which doesn't work of course...
David Nalesnik wrote a very versatile function that makes such
things very easy. You can find it in a thread titled "generalizing
offsets to properties" on -devel.
Indeed, very nice! Thanks for the link. Unfortunately, it doesn't
work with Stem.length at all because this is not an `offset'.
Have you tried using
\once \override Stem.length-fraction = #(magstep -n)
where n is a numeric value. Unfortunately the amount of shortening is
not consistent across all notes for a particular value of n. e.g.
\relative f' {
c
\once \override Stem #'length-fraction = #(magstep -3) c
e
\once \override Stem #'length-fraction = #(magstep -3) e
}
will shorten the stem on the E more than it will the stem on the C.
