\uppercase function

[Kieren MacMillan]

Hi all!

Anyone have a good \uppercase function they could share?

I tried to make one, and it doesn’t throw an error, but also doesn’t work:

\version "2.25.2"

#(define-markup-command (uppercase layout props arg) (markup?)
   (interpret-markup layout props (string-upcase (markup->string arg))))

\header {
  title = "My Awesome Piece"
}

\paper {
  scoreTitleMarkup = \markup \uppercase \fromproperty #'header:title
}

{ c1 }

Thanks,
Kieren.
