Apoligies about the nbsp's, not sure if it was Safari or gmail that put those in there.
Is there a way to access the pitch variable and put that where I have the \x so something like (and sorry about the javascript-y syntax) but something like x.pitch (but in scheme syntax of course) so \relative #( x.pitch #) {.....} or however it would look. I am tying to generate a bunch of exercise files of which there will be hundreds (and potentially thousands) of groups of notes and I want them arranged a certain way. And the note that I want the groups to be relative to changes based on the note that starts the group, and there are far too many to put the specific relative note in by hand. So I was hoping for a way to pass the entire group of notes into a function and use whatever note starts that group as the \relative note by way of a variable. There are probably other ways to skin this cat, and I may just have to change the way I generate the notes, but if I can access the pitch value and make \relative see it somehow, that might work. Thanks for the help!

The newfangled scheme functions (did I commit them already?) don't support ly:export (that would have been real hard to do), and anyway, ly:export only works for things that can be put into an identifier. You can't expect \relative \x to work, but you could make \x { ... } work in itself for making things relative to something. And \relative is a noop for unrelativable music. > How does one dereference a variable inside of a function? > > For instance if I sent in \x how do I say "use the value of x"?

What problem are you actually trying to solve? I don't see that this makes much sense. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
