All,
Going off the of the thread here:
and some personal email exchanges, I tried out a few things (found a working solution, though not ideal) and ran into something curious. I'd like to do something like the following, but it doesn't seem to work:
%%%%%%%%%
\version "2.19.36"
myStartTextSpan = #(define-music-function (mus) (ly:music?)
#{
\once \override TextSpanner.bound-details.left.text = "rit."
$mus \startTextSpan
#})
myStopTextSpan = #(define-music-function (mus) (ly:music?)
#{
$mus \stopTextSpan
<>^\markup \italic "a tempo"
#})
\relative c' {
\myStartTextSpan b'1
c1
\myStopTextSpan e,1
g1
}
%%%%%%%%%
This results in "unexpected EVENT_IDENTIFIER" errors at both
$mus \startTextSpan
and
$mus \stopTextSpan
When I put everything into a single _expression_ without using music functions, it works as expected:
\version "2.19.36"
\relative c' {
\override TextSpanner.bound-details.left.text = "rit."
b'1\startTextSpan
c1
e,1\stopTextSpan
<>^\markup \italic "a tempo"
g1
}
This is just a simple example. The real use-case has numerous other \override statements that should occur prior to \startTextSpan, but the general idea is the same.
Anyone know what's going on here?
Best,
Abraham
