I've been working on some patches to enable more flexible uses for the Keep_alive_together_engraver. Whilst I've achieved my particular use case, David K is (rightly) keen that any changes might also address (or at least not rule out) other potential improvements.
(If you're interested in the code, look here: https://codereview.appspot.com/308910043/) So if I could ask users for any situations where they can imagine this engraver helping, that currently don't work, or don't work easily. I'll start by describing my case, which came up on the list recently. Duplicating rehearsal, tempo, volta marks etc at multiple vertical positions in an orchestral score is possible with a custom MarkLine context (http://lsr.di.unimi.it/LSR/Item?id=1010), however this technique currently doesn't work in a Frenched score, as there may be passages where e.g. the brass are tacet so two MarkLines would be shown together. My fix makes it possible to set a context (Staff or MarkLine) to be kept alive only while there is another Staff in the group. See also the temporary divisi staves example here: http://lilypond.org/doc/v2.19/input/regression/a6/lily-436997bb.ly as another use of the engraver. Many thanks for your input. -- Mark Knoop _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
