Programming error when using very many grace notes [was: Re: ]

[Malte Meyn]

Hi Alex,

please say which LilyPond version you are using. Issues 2 and 3 probably 
are no bugs but partly intended behaviour (although I really much would 
like at least a warning and maybe an error when a line is longer than it 
should be like TeX’s “Overfull hbox”). And I cannot reproduce your first 
issue so please give us a minimal example like the following that 
illustrates your problem:

%%%%%%%%%%%%%%% BEGIN MINIMAL EXAMPLE (all three issues)
\version "2.18.2"

\relative {
  % issue 2: very long instrument name
  \set Staff.instrumentName = "This is a very long instrument"
  % issue 3: too many notes per line
  \repeat unfold 64 d'64
  % issue 1: very many grace notes
  \repeat unfold 1024 { \grace e8 d }
}
%%%%%%%%%%%%%%% END MINIMAL EXAMPLE

Now here comes a solution for issue 2 and 3:
2. Change the indent (and if you use shortInstrumentName also the 
short-indent) as shown in this pdf: 
http://joramberger.de/files/LilypondSpacing.pdf
3. Use a very small font size or, probably better, allow line breaks at 
some reasonable points in the measure:

  \repeat unfold 16 d'64 \bar ""
  \repeat unfold 16 d64 \bar ""
  \repeat unfold 16 d64 \bar ""
  \repeat unfold 16 d64
