It seems that \fromproperty doesn't return an empty stencil, even if
the property given in the argument is empty.
Is there a workaround for that ?
I use a \when-property markup command to handle that:
#(define-markup-command (when-property layout props symbol markp)
(symbol? markup?)
(if (chain-assoc-get symbol props)
(interpret-markup layout props markp)
> (ly:make-stencil '() '(1 . -1) '(1 . -1))))
\when-property #'header:title \underline \fromproperty #'header:title
Yes, it works perfectly. (Ok, I don't really understand why now, but i'll
try to )
Thank you very much.
Gilles
