Re: Completion_heads_engraver for line-ends only?

[David Poon]

Note that some durations still require a tie despite using barless notation (e.g. semibreve + crochet), so it wouldn't be completely heretical to have a few ties across barlines. The whole problem lies in using scores instead of partbooks. :)

I've seen one engraver use custodes at the end of a line to signal notes being carried over the line break (rather than foreshowing the next note), though I personally still find the empty space starting the following line unsettling.

I am afraid this would be exceedingly difficult technically.
Engravers run way earlier than line breaking, so the only
option would be to let the engraver create both notations
(with notes straddling over bar lines and with tied notes),
and remove one of them later, but there is a lot of code in
between that is not prepared for ignoring the collisions
that will unavoidably ensue, it would have consequences on
horizontal spacing, etc.

Also, I have to say I would find it confusing as a performer.
In your shoes, I'd go either for modern notation with ties, or
for ancient notation, but not a mixture of both.

Do you have an example?
