Hello, all!
I'm jumping in feet first, and would love a lifeguard to keep an eye
on me... =)
As a first project, I'm trying to create a function to add a dynamic
+text to a note event. From the docs, I realised that \displayMusic
is my friend, so:
%% CODE BEGINS
\version "2.9.6"
ppSempre = #(make-dynamic-script (markup #:line(#:dynamic "pp"
#:hspace -0.3 #:normal-text #:italic "sempre" )))
\relative c'
{
\displayMusic c4\ppSempre
}
%% CODE ENDS
which gives
%% OUTPUT BEGINS
(make-music
'EventChord
'elements
(list (make-music
'NoteEvent
'duration
(ly:make-duration 2 0 1 1)
'pitch
(ly:make-pitch -1 0 0))
(make-music
'AbsoluteDynamicEvent
'text
(markup
#:line
(#:line
(#:dynamic
"pp"
#:hspace
-0.3
#:normal-text
(#:italic "sempre")))))))
%% OUTPUT ENDS
So then I copied [most of] the output and wrapped it thusly:
%% CODE BEGINS
\version "2.9.6"
dwt =
#(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)
(list (make-music
'NoteEvent
'duration
(ly:make-duration 2 0 1 1)
'pitch
(ly:make-pitch -1 0 0))
(make-music
'AbsoluteDynamicEvent
'text
(markup
#:line
(#:line
(#:dynamic
"pp"
#:hspace
-0.3
#:normal-text
(#:italic "sempre")))))))
result-event-chord))
\relative c'
{
\dwt #'"f" #'"test" { c4 }
}
%% CODE ENDS
But I get
%% ERROR BEGINS
programming error: Spanner `DynamicLineSpanner' is not fully
contained in parent spanner `VerticalAxisGroup'.
programming error: no broken bound
programming error: no broken bound
%% ERROR ENDS
and the output has only the note and duration (correctly) with no
dynamic.
Any hints/corrections/suggestions would be appreciated.
Thanks,
Kieren.
