Markup : convert to v2.18/v2.19 generate error

[Pierre Perol-Schneider]

Hi All,

I'm trying to convert this v2.16 file : http://lilypond-french-users.1298960.n2.nabble.com/attachment/7581913/0/arnaud.ly

but this gives me
"error: unexpected post-event".

So I've come up with this function :

ti =
#(define-music-function (parser location button) (string?)
  (if cadb
    #{
      \markup
      \override #'(direction . 0)
      \fontsize #-1.5 #button
    #}
    #{
      \markup
      \override #'(direction . (rang button))
      \underline \fontsize #-1.5 #(touchnum button)
    #}))

but I'm still stuck with another error :

error: music function cannot return \markup \override #'(direction rang button) \underline \fontsize #-1.5 "3"

Herewith is a tiny example that shows the problem.

TIA, cheers,

Pierre
