Re: Overrun of right margin

Hi Andrew, hi Aaron,

Yep (also for future archive searchers) I can confirm that the right margin overrun results from the Lily default that glissando aren't breakable, as Aaron identifies.

It should be enough to include just ...

\override Score.Glissando.breakable = ##t

... to prevent this one particular instance of right margin overrun.

There are, of course, other conditions that can also cause right margin overrun. Jean Bréfort pointed to barline-crossing durations earlier in this thread, which can also cause right margin overrun. If you *want* barline-crossing durations (complexism or music before 1600) then you need to remove Lily's Forbid_line_break_engraver from every voice context in which barline-crossing durations occur. Something like ...

\context {

\Voice

\remove Forbid_line_break_engraver

}

... does the trick for all voices in your score.

Andrew, if you're engraving a lot of complexist music, I suggest removing the Forbid_line_break_engraver as a matter of course.

Trevor.

This is probably because glissandi are unbreakable by default. If you
have one overlapping a bar line, then LilyPond cannot break there.

Consider the following:

%%%%
\version "2.19.82"
{
\override Glissando.minimum-length = #5
\override Glissando.springs-and-rods = #ly:spanner::set-spacing-rods
\override Glissando.breakable = ##t
\repeat unfold 32 { f'8\glissando e''8\glissando } f'1
}
%%%%

If you omit setting 'breakable to true, you'll see the result extends
all on one line.
