Hi Fr. Samuel,
So far I’ve determined that the articulations property is a music-list, but I can’t
seem to figure out how to look inside the music-list to see if it contains a
HyphenEvent. I tried using (member 'HyphenEvent <music-list>) (and memq and
memv) to look at this, but this is always coming back false (i.e. not seeing the
HyphenEvent). Any hints from the scheme professionals?
Me not being a scheme professional by any means, nevertheless try:
#(define (hyphen? mus) (music-is-of-type? mus 'hyphen-event))
#(define (lyric? mus) (music-is-of-type? mus 'lyric-event))
#(display (map
(lambda (j) (if (lyric? j)
(any hyphen? (ly:music-property j
'articulations))))
(ly:music-property words_one 'elements)))
*Question to the acutal experts:* In some snippets I found on the
user-list, there are constructions like:
#(define (name-of music)
(ly:music-property music 'name))
#(define (lyric? music)
(eq? (name-of music) 'LyricEvent))
in contrast to my above definition of "lyric?" using music-is-of-type?.
1) Which variant is to be preferred?
2) What is the difference between 'LyricEvent and 'lyric-event ?
