% Hi people,
% here's what i want to do:
<<
{
\overrideProperty #"Score.NonMusicalPaperColumn"
#'line-break-system-details #'((alignment-distances . (30)))
a a a a
}
{ b b b b }
>>
% the override is very long, so i wanted to create a helper music
function. I tried this
staffdist =
#(define-music-function (parser location distances)
(list?)
#{
\overrideProperty #"Score.NonMusicalPaperColumn"
#'line-break-system-details
#'((alignment-distances . #'distances))
#})
<<
{
\staffdist #'(30)
a a a a
}
{ b b b b }
>>
%{
and it doesn't do anything. I tried adding/deleting apostrophes and
parentheses, but it didn't work. I don't see any example function
operating on lists in the Extending manual, so i'm a bit lost.
I had no problem with a similar function which operates on a pair and
overrides beam positions. I have no idea why this doesn't work.
what i'm doing wrong?
Janek
