Re: Non-local page-break oddities

I’m getting close to finished with my first Lilypond project, a book of some 30 scores.  I tried building the \book section piecemeal, including a handful of scores and tweaking the page breaks, and then another batch, and so on.

\book {  
  \scoreI  
  \pageBreak  
  \scoreII  
  \pageBreak  
  \scoreIII  
  \pageBreak  
  \scoreIV  
  \scoreV  
  \pageBreak  
  …  
  \pageBreak  
  \scoreXXXI  
  \scoreXXXII  
  \pageBreak  
  \scoreXXXIII  
  \paper { min-systems-per-page = 2 }  
  \scoreXXXIV
}  

This doesn't do what you think. In \book, a \paper occurring anywhere applies to the entire book, not only to the scores that follow it.

The weird thing is, if I comment out all a few \scoreX statements, the page breaks fall where I want them.  But when I compile the whole book at once, some scores start to stretch across multiple pages in ugly ways.

I have tried tweaking with lines like

\paper { max-systems-per-page = 8 min-systems-per-page = 5 }

in strategic places, but that still fails when I add enough scores.

(It looks like perhaps using \bookpart around chunks of the book might help, but that re-prints the book header when I don’t want it to, and I’m not seeing how to suppress that.)

Try

  \bookpart {
    \paper {
      bookTitleMarkup = ##f
    }
    ...
  }

It’s hard to give a minimal example without publishing my whole project in public.

It's hard to understand what the problem is without the project :-(

If you are comfortable with sending it to me privately, I can take a look.

Best,

Jean
