Re: hide and omit behaviour

[Andrew Bernard]

Hi Joram,

Rather than trying to figure pushing and popping state from a notional stack, I 
just do what you want with some simple functions. Crude but effective.

I have quickly adapted these three functions from ones I use to turn on or off 
tuplet brackets and numbers at will. I think you get the idea. Does this help?

\version "2.19.26"

% tuplet functions

tupletNumberOff = {
        %\once \override TupletBracket.bracket-visibility = ##f
        \once \override TupletNumber.stencil = #point-stencil
}

tupletNumberOffAll = {
        %\override TupletBracket.bracket-visibility = ##f
        \override TupletNumber.stencil = #point-stencil
}

tupletNumberOn = {
        %\override TupletBracket.bracket-visibility = ##t
        \revert TupletNumber.stencil
}


{
  \tupletSpan 4
        \tuplet 3/2 {
        a8-"default" a a
        \omit TupletNumber
        a-"omit" a a
        \undo \omit TupletNumber
        a8-"undo" a a
        \omit TupletNumber
        a-"omit" a a
        \once \undo \omit TupletNumber
        a-"once undo" a a
        a-"why not omitted again?" a a
        }
        r2
}

{
  \tupletSpan 4
        \tuplet 3/2 {
        a8 a a
        \tupletNumberOffAll
        a a a
        a8 a a
        a a a
        \tupletNumberOn
        a a a
        \tupletNumberOffAll
        a a a
        }
        r2
}
