Look at the grace part of its moment? I think music columns have a
property "when" or so recording it.
So look at the grace time component of note->get_column ()->get_property
("when") or so?

Ah yes, of course. And of course I only sketched the changes in
extender-engraver.cc and not yet in lyric-extender.cc and the latter
will likely render some of the former nonsensical.

Ouch. I think I am currently at the limit of my concentration and need
to go into bed. Coughing and hurting all over.
I'll try to get back to it later today.

Actually, this is a content vs. presentation issue. The current approach has
lyric extenders ‘hardcoded’ within the lyricmode input, whereas often it
depends on layout whether I want an extender printed or not:
– In tight horizontal spacing, we might not need an extender, but when spacing
is stretched, it might become necessary. This can come through different
\(page/line\) breaking, parallel contexts present only in some editions \(part
vs. score\), Completion\_heads\_engraver \(mensural without
barlines/transcription with barlines\).
– Long syllables might not need an extender, where short syllables do.
– Often, all voices share the same text, but have extenders in different
places. If extenders need not be given explicitly, the lyricmode input code can
be reused much easier.
After all, the extenders don’t add any additional meaning, but only serve to
improve legibility in such cases where they do.
This would require:
– Recognising the end of a word by absence of a hyphen.
– Comparing printed length of the melisma notes vs. the syllable, likely after
line breaking. After all, extenders will never influence horizontal spacing.
They might, however, affect vertical spacing. \(unless we chose to omit \(or
shift\) the extender in that case?\)
– Personally, I think very short extenders shouldn’t be printed. There should
be some kind of threshold.
It’s also one of the usecases where a proper representation of a ‘lyric word’
would be helpful, along with [issue 2458](#2458).
