Re: Include file handling in lilypond-book

[Karljurgen Feuerherm]

Hi Marc,

Good suggestion, but yes, I tried that, didn’t work. It seems that the include 
file is read, because the compiler doesn’t whine about undefined Ggrace, but 
that the variable is not expanded. I’m thinking a deficiency in the python 
script?

I don't know if I remember correctly, but I think I stumbled upon this 
problem before.
Have you tried to include a relative path?

\include "./lilypond-variables.ly"

   ^^

HTH,

Marc

Include file handling in lilypond-book

[Karljurgen Feuerherm]

Hello,

Putting together an exercise book using XeLaTeX and the lilypond environment. 
Everything works relatively well until I try to use an include file with 
variable definitions.

MWE:

% !TEX encoding = UTF-8 Unicode
% !TEX TS-program = LilyPond-Book
% !LILYPOND tex = xelatex
\documentclass{memoir}

% \newcommand{\Ggrace}{\grace { g''32 }}
\begin{document}
\begin{lilypond}
{
  \include "lilypond-variables.ly"
  \time 2/4
  \grace { g''32 } g'4  \Ggrace a'4  \Ggrace b'4  \Ggrace c''4
  \Ggrace d''4 \Ggrace e''4 \Ggrace f''4 g''4
  a''2 g''4 f''4 \Ggrace e''4
  \Ggrace d''4 \Ggrace c''4 \Ggrace b'4  \Ggrace a'4
  \Ggrace g'4
  \bar "||"
}
\end{lilypond}
\end{document}

LILYPOND-VARIABLES.LY:

Ggrace = {  \grace { g''32 }  }

The in-line g grace note is typeset just fine. The variable references, 
however, either choke, or (if I trash files after choking) are not expanded 
upon typesetting.

(I had originally tried to do this with a *tex include file with \newcommands, 
but that did not work either.)

The code below works fine in Frescobaldi:

\include "lilypond-variables.ly"
{
 \time 2/4
  \grace { g''32 } g'4  \Ggrace a'4  \Ggrace b'4  \Ggrace c''4
  \Ggrace d''4 \Ggrace e''4 \Ggrace f''4 g''4
  a''2 g''4 f''4 \Ggrace e''4
  \Ggrace d''4 \Ggrace c''4 \Ggrace b'4  \Ggrace a'4
  \Ggrace g'4
  \bar "||"
}

So I’m assuming there’s a trick to the placement/invocation of the include file 
which I’m not privy to…? Using macOS Sierra 10.12.5 (16F73) and TL 2016; 
LilyPond-Book engine 2.0.4 (2014/03/23).

Thanks!
