Hello, all --
Okay, I've got at least this much going:
%% CODE SNIPPET BEGINS
\version "2.9.6"
addDynText = #(define-music-function (parser location dyn text event-
chord) (string? string? ly:music?)
(let ((result-event-chord (ly:music-deep-copy
event-chord)))
(set! (ly:music-property result-event-chord
'elements)
(cons
(make-music 'AbsoluteDynamicEvent 'text (markup #:line
(#:dynamic dyn #:normal-text (#:italic text))))
(ly:music-property
result-event-chord 'elements )))
result-event-chord ))
\relative c'
{
\addDynText #'"pp" #'"sempre" <c d e>4 c
\addDynText #'"f" #'"(no, really)" <c d e>8 c c4
}
%% CODE SNIPPET ENDS
However...
1. I'd like the syntax to be easier -- maybe something like
<c d e>8\addDynText #'( f . "(no, really)" )
or something even slicker, if anyone has a recommendation. Anyway, I
don't know how to do that -- it would involve (car args) and so on,
and I'm not there yet.
2. I don't know how to (or even where to look to find out how to)
change the self-alignment-X or X-offset property of an
'AbsoluteDynamicEvent within the Scheme code. I tried to work it out
by looking at the existing Lilypond (Scheme) code, to no avail (yet).
3. I'd love someone to tell me that I'm on the right track -- e.g.,
that I'm not bypassing the parser inadvertently, or creating some
endless loop, or double-garbage-collecting, or "this would be better
in C++", or whatever.
Hints, pointers, code samples, solutions, etc., would be greatly
appreciated. =)
Thanks,
Kieren.
