Hello, I make some tweaks to the default layout, and I would want to conditionally add an `arr.` before the arranger name on one of my custom layout. This is used to produce two music sheets, one compact and one large, the large containing the `arr. Somebody`, and the compact containing `Somebody`
I tried this: ``` \version "2.24.1" \header { arranger = "" % or arranger = "Somebody" } %something #(define (should-not-print-arranger layout props) (eq? "" 'header:arranger)) % something else % in the large.ly file: \unless \should-not-print-arranger \smaller \italic \line { "arr." \fromproperty #'header:arranger } ``` but this dont work. It works if I use `should-print-all-headers` in the `\unless` block. I have a thousand browser tabs open on different parts of the lilypond / guile documentation and source code, but I can't find what is my error, any help would be greatly appreciated.
