Re: Extra space at the beginning of the bar

Hi Paolo,


You’d have to add an equivalent tweak for any prefatory material (Clef, KeySignature, etc.).

Doesn't work for skip events too...

1. What music do you have that doesn’t include a grob of any sort in the first moment of the measure?

Have a look at this snippet (  http://lilybin.com/p2whaw/1  ) :

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

upper = {

   c'8 c' \change Staff = "down" g \change Staff = "up" c' 

   \change Staff = "down" \stemUp g g \change Staff = "up" c' \change Staff = "down" c'

}

lower = { 

   s8\f s s\mf s s\mp s s\p s

}

\score {      

  \new PianoStaff

  <<         

    \new Staff = "up"   << \upper >>

    \new Staff = "down" << \clef bass \lower >>

  >>  

}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

... as you can see, there's no way to add extra-space at the beginning of the measure, without work-arounds (like the one you just proposed).

2. How about

    { \once \hide Rest \tweak Rest.extra-spacing-width #'(-10 . 0) r4 c'4 4 4 }

It does the job but I don't think it's a good solution. I wonder if is there a more general solution, given that in cross-staff music, it frequently happens that I have to place dynamics like the snippet above, and skip-events cause issues for the alignment of the attached items.

Again: I think that these events must be managed as graphic objects, with the extra-spacing-width and X-offset properties. I don't understand why they don't implement these interfaces and I wonder if is there a way to override this behaviour (with some _global_ scheme code)
