Re: lilypond-book fragment with ties/slurs continuing over the end of the fragment

[Vaclav Smilauer]

Mats,

thanks for the great idea. (I still think it is a hack but I am the last person
to suggest that there should be a built-in functionality for this in Lily.) I
post my solution here, but it depends on the format of the file generated by
lilypond-book. Someone can add it to tips and tricks page, if it considered
useful enough? Regards,

VS.

1. Simple case, just the first system (eats all input including the next
\includegraphics)

 \def\betweenLilyPondSystem#1\includegraphics#2{\relax}
 \begin{lilypond}...

2. Customizable case: show first N systems, discard the rest:
 
 \def\justFirstNSystemsPlease#1{
    \def\eatNextSystem##1\includegraphics##2{\relax}
    \def\betweenLilyPondSystem##1{
       \ifnum##1<#1\else\eatNextSystem\fi
    }
 }

 \justFirstNSystemsPlease{2}

 \begin{lilypond} ...
