Can anybody explain to me why collecting LyricText grobs in the
StanzaNumber's side-support-elements is necessary?
For the record, to answer my own question:
This is not necessary as long as the Stanza_number_align_engraver is
\consist'ed in the Score context (as it is by default). This engraver
has only one job, namely, to put /all/ LyricText grobs at a given time
into the side-support-elements array of /all/ StanzaNumber grobs, so
that the lyric syllables of /all/ Lyrics contexts get aligned together
after /all/ Stanza numbers. There's still a comment by Han-Wen in
stanza-number-engraver.cc
/*
TODO: should make engraver that collects all the stanzas on a higher
level, and then groups them to the side. Stanza numbers should be
all aligned.
*/
from 2003 which probably should have been removed when the
Stanza_number_align_engraver was added in early 2004.
It's possible to remove the Stanza_number_align_engraver from the Score
context in case one does not want the global alignment of Lyrics to
stanza numbers. If this is done, it becomes important that the
Stanza_number_engraver still collects the LyricText grobs of its own
Lyrics context in order to make sure that lyrics and stanza numbers do
not overlap.
