Re: predicate for \lyricmode

2018-03-20 Thread Jan-Peter Voigt 
Yes, but you might write one that checks if the music expression does contain 
elements of a certain type. It is possible, but I can't tell if its reasonable.

Hi all,

is there a LilyPond predicate for a \lyricmode expression?

\version "2.19.80"

test =
#(define-void-function (text)(ly:music?)
(display text))

text = \lyricmode { a b c }
\test \text

does work, so ly:music? accepts the lyricmode expression. But is there
a narrower predicate I can use to expect lyrics to be arguments for a
function?

No.  It's just an ordinary music expression containing different
elements conveniently entered with \lyricmode .


Thank you.

No.  It's just an ordinary music expression containing different
elements conveniently entered with \lyricmode .

predicate for \lyricmode

2018-03-20 Thread Urs Liska 

Hi all,

is there a LilyPond predicate for a \lyricmode expression?

\version "2.19.80"

test =
#(define-void-function (text)(ly:music?)
   (display text))

text = \lyricmode { a b c }
\test \text

does work, so ly:music? accepts the lyricmode expression. But is there a 
narrower predicate I can use to expect lyrics to be arguments for a 
function?
