Re: variables in \book { }

[Jan-Peter Voigt]

Hi Graham,

I didn't went through the whole thread, but IIUC, the problem is about
defining variables inside a pair of braces. Sometimes I use a helper
function to define variables:

%%% snip %%%
\version "2.19.35"

% a little helper function using ly:parser-define!
pdefine = #(define-scheme-function (sym val)(symbol? scheme?)
(ly:parser-define! sym val))

\book {
% define "music"
  \pdefine music \relative { c' d e f }
  \score {
    \music
  }
}
%%% snip %%%
of course, you might also just write
$(ly:parser-define! 'music #{ \relative { c' d e f } #})
without defining "pdefine" (or whatever you like to name it, but avoid
"define" ;) )

HTH
