Hi,
as Helge wrote the toc-items are accumalated per file.
The toc-item-list is cleared after one _entire_ session, so that
lilypond book-1.ly book-2.ly
will cause no bleed over.
(try to comment the line
(call-after-session (lambda () (set! toc-item-list '())))
in toc-init.ly to force such a bleed over)
Though, there is no mechanism in place to clear that list after one of
several books in the same ly-file.
Pity to say, it's beyond my depth to provide such a mechanism.
Looks like a bug for me too.
As a workaround I extended the code from toc-init.ly
Now you could (and should) specify the book you refer to while calling
\tocItem and add an override to table-of-contents
Syntax-example:
\include "my-toc-init.ly"
\book {
\markuplist \override #'(name . book-1) \table-of-contents
\score {
\tocItem #'book-1 \markup test1.1
\layout {}
}
\score {
\tocItem #'book-1 \markup test1.2
\layout {}
}
\score {
\tocItem #'book-1 \markup test1.3
\layout {}
}
}
Example-file and my-toc-init.ly attached
Please note:
Doing it this way call-after-session gives a (not surprising) error,
so I had to comment this line.
Ofcourse now you may experience bleed overs while compiling multiple
ly-files, if you _not_ specify the book.
HTH,
Harm
