Make TOC entries available to LaTeX

[Urs Liska]

Hi all,

I'm preparing an automated edition process using LuaLaTeX, Pandoc and LilyPond.

After some experimentation I have come to the conclusion that I'll have to insert the multi-movement score as a single PDF created by LilyPond (but through lyluatex to make use of caching and the layout mechanics).

I first had used lyluatex's facility to include the score's system by system and print all the titles with LaTeX, but this didn't work out - for the first time I realized that lilypond-book-preamble.ly makes the vertical staff-staff spacing as tight as possible, which often makes the page layout pretty bad. Creating the movements separately is not an option either because not all movements will start on a new page.

So now I have included a multi-movement score in the LaTeX document and don't know how to add TOC entries (in LaTeX) for the movements. I can see two possible ways, but don't know if they are really possible and if so how to approach them:

• Is it possible to insert something in the PDF output that LaTeX can pick up as TOC entries?
  (actually I doubt this is possible, but since it would be the easiest way I thought I'd ask anyway)
• Can I reliably retrieve the current page number of a given score's title block?
  With that information I could write them to a log file and read that later in LaTeX.

TIA
Urs

PS: I don't know if it matters but the file is produced using ly:book-process etc.
