I did notice that the \markup defeats lyric ties.
You can special-case bare strings to return a string:
\version "2.22.1"
openQuote =
#(define-scheme-function (text) (markup?)
(if (string? text)
(string-append "“" text)
#{ \markup \concat { “ #text } #}))
closeQuote =
#(define-scheme-function (text) (markup?)
(if (string? text)
(string-append text "”" text)
#{ \markup \concat { #text ” } #}))
\relative { \time 3/4 e'4 e4. e8 d4 e d c2. }
\addlyrics { \openQuote O~In -- com -- pa -- ra -- \closeQuote ble,
said she }
It’s not a big deal—that combo only occurs once in the songs I have. But now
I’m curious. What do lyric syllables get turned into? A LyricEvent? Is it
possible to build and return a LyricEvent from a function?
Yes. Add \displayMusic before any music to see
how it could be built in Scheme. The code might
look like
openQuote =
#(define-music-function (lyric-event) (ly:music?)
(display-scheme-music lyric-event)
(make-music 'LyricEvent
lyric-event
'text
(let ((text (ly:music-property lyric-event 'text)))
(if (string? text)
(string-append "“" text)
#{ \markup \concat { “ #text } #}))))
