Re: List of articulations into a scheme variable

[Paolo Prete]

Hello Simon,
my goal is to create a set of functions for manipulating a single note passed 
as a parameter, in many ways.This is the basic of music variation.
For example:
(function 1)c'4 >  r8 c'8
(function 2)c'4 >  c'16 c'16 c'16 c'16
(function 3)c'4 >  r4 \grace c'8 
etc.

 Hi Paolo,

as more questions like these pour in, it would indeed be interesting to 
know what you are trying to achieve/why you need this function. :-)

Best, Simon

How can I extract and print the list of articulations, keeping them 
into a new variable, from an argument passed as ly:music to a scheme 
function?
I tried with the snippet below: it compiles but the articulations are 
not shown.



fun = #(define-music-function (parser location note) (ly:music?)
  (let
    (
 (mypitch (ly:music-property note 'pitch '()))
 (myduration (ly:music-property note 'duration '()))
 (myarticulations (ly:music-property note 'articulations '()))
    )
#{$mypitch $myduration $myarticulations  #}))

{
 \fun c'8-> e' f'
}


Thanks for your help.

myarticulations isn't an articulation but a list of articulations.  Try
$@myarticulations to splice them in.
