Sorry for the noise earlier, Kieren.
See the known issues in Notation Reference 6.4.1.:
The markup-list argument of commands such as #:line, #:center, and #:column
cannot be a variable or the result of a function call.
(markup #:line (function-that-returns-markups))
is invalid. One should use the make-line-markup, make-center-markup, or
make-column-markup functions instead,
(markup (make-line-markup (function-that-returns-markups)))
So the code that works is:
\version "2.12.2"
#(define-markup-command (test layout props stringA stringB) (string?
string?)
(interpret-markup layout props
(markup (make-column-markup (list stringA stringB)))))
\score {
c^\markup \test #"one" #"two"
}
HTH,
Carl
