Can staff size variable be something other than a counter? about lyluatex HOT 4 CLOSED

Could you test last commit, please ? It should work like this. On a further step, I think I'll add a command to automatically scale default staffsize pending on document's font size.

Tested and found that while \renewcommand{\staffsize}{(* 20 17/12)} doesn't work, \renewcommand{\staffsize}{(20*17/12)} does. Since the first is the Scheme syntax for the math (in particular the multiplication) and the second is Lua syntax, I'm guessing that Lua is trying to process the contents of \staffsize before passing it on to Lilypond rather than simply treating it as a string to be passed along. However, I actually don't mind, and indeed prefer, that in this case. Lua's syntax for mathematical operations is much more natural than Scheme's.

So, bottom line: what you did works and is, I think, better than the equivalent in lilypond-book.

Perfect ! I leave this open till I've made what I told about auto scaling. Thank you !

19d85ff should definitely fix this issue ; feel free to re-open it if there are bugs.
From now, if \staffsize is defined to 0, scores will be auto-scaled to stick with font size.
