Experimenting with custom-line-breaks-engraver, I've found that it doesn't work correctly if the number of bars to be printed per line exceeds 9, e.g.       \consists #(custom-line-breaks-engraver '(10))

A 37 bar song comes out with 10, 10, 5, 5 and 7 bars per line, instead of the expected 10, 10, 10 and 7.

Specifying (10 10 10 7) doesn't work either.

(If you use the overrides described below, you will need to specify your song fully like the above.)

 

This isn't a real problem for me, as I usually use 4 bars to the line for lead sheets (or 8 bars to the line if the notation is sparse and the song is long).

I don't have any knowledge of Scheme to correct such a brilliantly useful piece of work - it's going to save me hours of time messing about with \noBreak and \break commands!

I can't say I've used the custom-line-breaks-engraver, but whenever I need to engrave something particularly tight, I like to use the following two overrides:

\layout {

  \override Score.NonMusicalPaperColumn.line-break-permission = ##f

  \override Score.NonMusicalPaperColumn.page-break-permission = ##f

}

These force LilyPond to break only when YOU tell it to, via \break and \page Break. You may not need the page-break one.

Yes, exactly.  There is a note to this effect in the snippet description of this engraver found here: http://lsr.di.unimi.it/LSR/Item?id=838. In the code, there are commented-out lines which demonstrate the overrides needed for forcing your wishes on LilyPond when the program considers the result too cramped.

Hope this helps,

David.
