What's the status of this? I cannot find an issue on the tracker.

something?
A tracker entry should be made using the example and description
that Jan provided above. I'd rate it low.

I think i have an idea how to explain this bug.
I suppose it happens because LilyPond is not aware that the dot is in
voiceTwo context (and therefore lower than usual).
compile this:
{ g'4.*1/32 d''!32 g'4.*1/32 e''!32 }
{ \voiceTwo g'4.*1/32 \voiceOne d''!32 \voiceTwo g'4.*1/32 \voiceOne e''!32 }
In the upper line, the first accidental (on d'') is too low to move
left (it would collide with the dot). The second accidental (on e'')
is high enough to be moved over dot. Everything fine here.
Now in the second line the music is the same except that dotted notes
are in lower voice. This makes the dots move down, they are a whole
staffspace lower. However, Lily fails to notice that, and engraves the
naturals exactly like in the upper line.

This two-bar example contains several difficult music-engraving issues, especially if I include the enharmonic spellings and key cancellation from the original edition. I think the release candidate does a decent job. Yes, although I dislike the excessive overlap of the ledger line and note with the bar line at the end of the first bar. 2.12 was better in that respect. That overlap (seen only with tight spacing) bothers me as well. The re-fix to lyrics spacing under melismata put the clearance over bar lines /almost/ back to what it was in 2.12.3, but one regtest with lyrics passing close to a bar line broke if I increased the clearance any more (without doing extreme things to lyrics). This is noted as part of issue 1229. I hope we can just increase the clearance around all things in 'non-musical' columns. We would need to adjust a couple reg tests to accommodate this, but still test what we really care about. -Keith ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
