Hi Urs,
I guess you are missing the wrapping lambda:
lilystring =
#(define-scheme-function (mus)(ly:music?)
(with-output-to-string
(lambda () #{ \displayLilyMusic #mus #})
))
test = \lilystring \relative { c'4 }
#(display test)

I have a ly:music? argument and want to store the LilyPond
representation as a string, that is I want to have a string with the
content that \displayLilyMusic prints to the console.
From what I know I have to provide a port to which \displayLilyMusic's
output is redirected and that I can then store. But For some reason
(well, that includes the "conciseness" of the Guile reference manual
...) I don't get it done.
\version "2.19.80"
#(define format-ly-music (mus)
(dont-know-what-to-do-here))
#(define my-var (format-ly-music #{ c' #}))
looks like a MWE for what I need.
From the reference I would have thought that call-with-output-string
would be what I need, but I don't get it to work as it complains about
the "unspecified" argument.
Any pointers?
Thanks in advance
Urs
