Hi!
I need to obtain a list of accordion registers.
I know I can engrave them using:
#(use-modules (scm accreg))
\markup \line {
\discant "1"
\discant "10"
\discant "101"
\discant "121"
\discant "21"
\discant "11"
\discant "120"
\discant "110"
\discant "1+0"
\discant "100"
\discant "11+0"
}
But I want to pass them in a markup function as a list.
regList = #'("1" "10" "101" "121" "21" "11" "120" "110" "1+0" "100"
"11+0")
I've tried map, for-each, do, let loop.... but I can't find a way to
do this.
Someone can help me?
thanks
Davide
Hi,
Just to add to Harm's answer, there is list splicing, like this:
\version "2.23.0"
#(use-modules (scm accreg))
regList = #'("1" "10" "101" "121" "21" "11" "120" "110" "1+0" "100"
"11+0")
\markup \line {
#@(map (lambda (s) #{ \markup \discant #s #}) regList)
\eyeglasses
}
% Alternate method
%
(https://lilypond.org/doc/v2.22/Documentation/extending/how-markups-work-internally)
\markup \line {
#@(map make-discant-markup regList)
\eyeglasses
}
The advantage is that you can have more than just this list of
arguments in the \line (I put \eyeglasses for the sake of example).

Best,
Jean
