Hi David,
'beam-gap is now a pair.
So I'm not sure if it should be
(car (ly:grob-property grob 'beam-gap))
or
(interval-length (ly:grob-property grob 'beam-gap))
Currently I haven't found a proper documentation:
git grep beam-gap
Documentation/misc/CHANGES-1.3:beams on whole notes. 'beam-gap' had been rename
Documentation/misc/ChangeLog-2.1: lines for falling into beam-gap.
lily/beam.cc: Interval gap_lengths = robust_scm2interval (me->get_property ("be
lily/beam.cc: "beam-gap "
scm/define-grob-properties.scm: (beam-gap ,number-pair? "Size of a gap in a
scm/define-grobs.scm: (beam-gap . ,ly:beam::calc-beam-gap)
Quoting "Documentation/misc/CHANGES-1.3":
1.3.153
=======
[...]
* Chord tremolo fixes: shift beams vertically on whole notes. Center
beams on whole notes. 'beam-gap' had been renamed to 'gap', but only
for reading.
I'm investigating further.
