Re: Acciaccatura distoring spacing

[Stefano Troncaro]

Oh I see, troubleshooting in big projects like what you describe can be so painful.

Hopefully you figure out specifically what in your poly-mark-engraver.ily is conflicting with overriding the SpacingSpanner. Perhaps if you manage to isolate the problem and make a short example showing the bizarre results you described someone in this list will be able to figure out what is happening and how to fix the poly-mark-engraver.

Anyways, I'm happy you solved it!

Hi Stefano,

I have now re-read the Horizontal Spacing section, and I am a bit wiser
than I was.

When I tried it, the fix you suggested worked perfectly for the snippet
in my email.  But I had great difficulty when I applied it to my actual
score: I kept getting numerous warnings:

        programming error: Cannot determine neighbors for floating column.
        continuing, cross fingers

Also, depending where I began/ended the strict-grace-spacing, I
sometimes had really bizarre results with a barline in completely the
wrong place and actually passing through noteheads!

After about 2 hours trying to isolate the cause, I found that it was
due to the fact that my default include file itself includes poly-mark-
engraver-ily.  I disabled this, and then recompiled the whole score
(all 150 pages of it).  To my great relief I found that there were no
problems: clearly I have not actually used the poly-mark facility in
this score.

Thank you very much for your help on this.

David
