Oh, the $(if ) method can perfectly handle variables which are a book. It is just LilyPond that does not accept a book identifier at top level. So you have to write something like \book { $(if includeGuitar GuitarBook) } and rely on an empty book not having an effect. Yes, this is a bit awkward. If you are fine with downloading, compiling, and installing _source_ to a degree that you do it without asking twice just because of some outdated information, tracking the development version (including testing out patches as they come) will not likely be a big step for you. And anyway: it is likely that you have now LilyPond 2.15.9 plastered all over /usr/local already, and you might as well plaster the current development version over it instead of trying to remove all that so that it does not shadow "standard" precompiled versions. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
