Hi Joram,
I second Andrew's call for an example.
Would be nice do know more exactly what you're trying to achieve.
Please post some example you would like to see working, even if it
fails currnetly.
That said, probably the code below may be a starting point.
It's only a proof-of-concept based on fromproperty-markup. Right now
it's likely easy to break.
Anyway:
\version "2.19.51"
#(define-markup-command (test layout props arg)(symbol?)
#:properties ((proc '()))
(let* ((target (chain-assoc-get arg props))
(target-string (markup->string target))
(output
(if (or (null? proc) (string-null? target-string))
target
(proc target-string))))
(if (markup? output)
;; prevent infinite loops by clearing the interpreted property:
(interpret-markup
layout
(cons
(list (cons symbol `(,property-recursive-markup ,symbol))) props)
output)
empty-stencil)))
#(define (test-proc xy)
(lambda (strg)
(if (string? strg)
(format #f "My ~a is: ~a" xy (string-upcase strg))
strg)))
\paper {
oddFooterMarkup =
\markup \column \box {
\override #`(proc . ,(test-proc "title")) \test #'header:title
\override #`(proc . ,(test-proc "subtitle")) \test #'header:subtitle
\override #`(proc . ,(test-proc "subsubtitle")) \test
#'header:subsubtitle
\override #`(proc . ,(test-proc "composer")) \test #'header:composer
\override #`(proc . ,(test-proc "meter")) \test #'header:meter
}
}
\header {
composer = \markup { "xxyyzz" "foo" }
title = "title"
meter = \markup \rounded-box { "meter" \musicglyph #"scripts.segno" }
subtitle = \markup \draw-line #'(10 . 0)
subsubtitle = \markup \with-color #red"subsubtitle"
}
\markup \null
Cheers,
Harm
