You could do something at the lines of below, I doubt you'll be very
happy with it, though.
\version "2.19.65"
scI =
\score {
{ r2 }
\header {
piece = "PIECE-I"
%% needed to distinguish from "piece"-settings in other scores
pieceI = "PIECE-I"
}
}
scII =
\score {
{ r2 }
\header {
piece = "PIECE-II"
pieceII = "PIECE-II"
}
}
scI-header = #(ly:score-header scI)
scII-header = #(ly:score-header scII)
#(define-markup-command (markupWithHeader layout props markup) (markup?)
"Interpret the given markup with the header fields added to the props.
This way, one can re-use the same functions (using fromproperty
#'header:field) in the header block and as top-level markup."
(let* (
;; TODO: If we are inside a score, add the score's local header block, too!
;; Currently, I only use the global header block, stored in $defaultheader
;; Make this list an argument of the markup-command?
(scopes
(list
$defaultheader
scI-header
scII-header
))
(alists (map ly:module->alist scopes))
(prefixed-alist
(map (lambda (alist)
(map (lambda (entry)
(cons
(string->symbol (string-append "header:"
(symbol->string
(car entry))))
(cdr entry)))
alist))
alists))
(props (append prefixed-alist
props
(layout-extract-page-properties layout))))
(interpret-markup layout props markup)))
\markup
\markupWithHeader {
\wordwrap {
Pieces below are named \fromproperty #'header:pieceI and
\fromproperty #'header:pieceII . %% Can't avoid space before dot easily
}
}
\scI
\scII
Cheers,
