I produce a lot of conductor's scores (with one system to a page) but
I've always found the spacing to detract a lot from the overall
excellence of the typesetting. I've just tried out the new code on one
of my scores and I must say I am very impressed with the result. In
fact, I'm going to print my most recent score and replace the one I
delivered a couple of weeks ago. It is far, far better.
I don't usually use a lot of the fancier layout stuff, so I'm
wondering what you have removed from this version. However, I would
most certainly use some of the grouping schemes Reinhold mentioned in
his message.
As of my latest push, I think there are no regressions in the configurability, although some tweaks got a bit uglier (to fix a lyric line, you need to override next-staff-spacing on the staff above it).
What I would ideally like (for systems-per-page = #1) is for the top
line of the top staff and the bottom line of the bottom staff to be
the same for every page, and everything suitably spread out
between. In other words, the top and bottom staves should be given
absolute positions and everything else is calculated afterwards.
With first-system-spacing and last-system-spacing in the paper block, this is now achievable:
\paper {
first-system-spacing = #'((space . 20) (stretchability . 0))
last-system-spacing = #'((space . 20) (stretchability . 0))
}
It isn't perfect, though, because it doesn't (yet) consider the top-matter or the bottom-matter. For example, the top staff of the first page will be above the top staff of the second page because the first page doesn't have a page number and the second one does.
