I'm sure that you properly studied the patch you are commenting.
For all those who did not: The following lilypond source demonstrates how to generate only explicitly requested extenders:
Well, I think we can agree that we are not going to require everybody who wants to use LilyPond to study patches rather than the documentation. Those who actually studied the documentation part of the patch would likely use \forceExtender
to actually force an explicitly requested extender (which was what I was talking about) though it is not clear how this would interact with the no-extender
property without studying the patch. The point was that we already had a user interface for forcing an extender.
At any rate: is there any problem preventing pushing the branch that this was developed in as refs/heads/dev/issue4509
so that I can take a look at making it accept explicit extender events with the previous syntax?

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.
