Hello Valentin,
thanks for your help!
I try to explain better what I need to do. Suppose that my score is divided
into three sections. The first one has not only notes, but a title too.
I need to render the sections all together or individually. The first
obvious way to do that is write the score in the form:
%%%%%
\markup { "My-Title" }
{
% SECTION 1 (title + notes)
{ c'1 c' d' d'\pageBreak }
%SECTION 2
{ c'1 c' d' d'\sustainOn\pageBreak }
%SECTION 3
{ c'1 c'\sustainOff d' d' }
}
%%%%%
and then comment or comment out parts of the score that I don't need to
render. So, for example, if I need to render only section 2, I would
comment section 3 and section 1 but I have to comment the markup block
separately as well: this is unwanted, because the markup belongs to section
1 context. Instead, it would be more appropriate to exclude automatically
the markup block when section one is not included.
Note that putting the sections into separate files, as you suggested, does
not solve the problem: instead of commenting blocks of code, I would have
to exclude both the file associated to the markup and the file associated
to section 1, if I want to render section 2.
Now, if I try to by-pass the problem with a \book context, I can embed the
markup into section 1:
%%%%%
\book {
% SECTION 1 (title + notes)
\markup { "My-Title" }
{ c'1 c' d' d'\pageBreak }
%SECTION 2
{ c'1 c' d' d'\sustainOn\pageBreak }
%SECTION 3
{ c'1 c'\sustainOff d' d' }
}
%%%%%
In this way, I could embed the markup into section 1, but it won't work for
another reason: the presence of the pedal needs that all the sections
belong to the same context. Note too that if I tweak sections of a score
into separate scores, I would have a logical mismatch between the syntax
used for blocks of code and what that blocks of code effectively represent,
which is unwanted too.
Hope this is more clear. Unfortunately the problem is tricky (and I hope
I'm wrong, so that there is already a right approach for it)
Best,
Paolo
