Of course I can do
circlefunc = \markup\circle\etc
\markup \test \circlefunc "whatever"
You can? Have you tried? \circlefunc here is quite equivalent to
\circle .
Hm, I think I do not understand. With
test =
#(define-scheme-function (enclosure content)
(markup-function? markup?)
(list enclosure #{ \markup \box #content #}))
I can do and compile
\test \markup \circle \etc "whatever"
as well as
circlefunc = \markup\circle\etc
\markup \test \circlefunc "whatever"
but
\markup \test \circle "whatever"
fails with
/tmp/frescobaldi-7l5ntq0c/tmp1iduvtxw/document.ly:8:15: Fehler: syntax
error, unexpected MARKUP_FUNCTION, expecting \header
\markup \test
\circle "whatever"
/tmp/frescobaldi-7l5ntq0c/tmp1iduvtxw/document.ly:8:33: Fehler:
Haupt-Eingabe nicht beendet
\markup \test \circle "whatever"
schwerer Fehler: gescheiterte Dateien:
"/tmp/frescobaldi-7l5ntq0c/tmp1iduvtxw/document.ly"
So, I can't believe that \circlefunc and \circle should be actually
equivalent.
