If you're not that patient, however, or you'd rather do them yourself, I've suggested a few things below. > > 1. on the regression test included in the patch, the output looks like: > ______ ______ ______ > > | 1| |2 | | 3| > |blabla| |blabla| |blabla| > |blabla| |blabla| | | > |blabla| |blabla| | | (with ragged-bottom=##t) > | > | | | | |taglin| > > ------ ------ ------ > That is, although the text could fit on two pages, three pages are > created, with a lot of white space left at their bottom. I suspect that this is because Line_details (Prob*) (in constrained-breaking.hh) makes up values for certain properties instead of reading them from properties of the Prob*. If that doesn't fix it, have a look at the force-calculating routines in Page_spacer::calc_subproblem and try to see why it is prefering solutions with more pages. > > 2. setting the next-space or next-padding properties to zero results to > wrong spacing.

The first page has a relatively small force which hardly affects the blablah springs but has a big effect on the system spring. The second page requires a very strong force to fit the lines in at all, so it stretches out the stiff blabla springs. I'm not sure how you would fix it,though. _______________________________________________ lilypond-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/lilypond-devel
