Hello,
I think that a very useful function would be a way to highlight or change the color for all the objects that are causing a collision.
Is there already some code for that?
Well, you would need to define what exactly _is_a collision?
Printing one grob above the other?
No, can't be a sufficient condition.
Look at this code:
{
\override Stem.color = #red
\override Stem.layer = -1000
b8[
\override Stem.layer = 1000
b8]
}
Obviously the Clef collides with StaffSymbol, as well as the TimeSignature.
The NoteHeadcollides with the LedgerLine and Stem.
The Stem collides with the Beam, which collides with the StaffSymbol.
Ofcourse all this is wished.
How to limit to unwished things?
And if unwished things happens, then because Grobs are not aware of each other. Making it difficult to get something like a "collision yes/no"-info out of LilyPond....
I don't see how to solve.
Cheers,
