Your snippet behaves exactly like you tell it. Or in other words:
You tell it to omit numbers and then say "don't omit once" and it
does exactly that. After it is back to omitting mode.

The following snippet shows this:

\version "2.18.2"
{
  \tupletSpan 4
  \tuplet 3/2 {
a8-"default" a a
\omit TupletNumber
a-"omit" a a
\once \undo \omit TupletNumber
a8-"once undo" a a
%\omit TupletNumber
a-"default again" a a
a a a
a-"still default" a a
  }
  r2
}

Michael

I don't know but I guess the "\once" does not work in this case
because it pops the "\omit" off the stack and does not push it back.

Not sure pushing things back is part of the "\once" functionality.

As I understand "\once" something like 
"\once \show TupletNumber"
would work but I don't know of it's existance...

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?

Andrew

% 

\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
}

It isn't.  Correct.  Plain context properties don't have either stack or
the subproperty complications of \override, so \once\unset, as opposed
to \once\revert, indeed works.

Try looking in the manual for how to set the _style_ of tuplet numbers.
I think this works by overriding the stencil callback, so just doing
\once followed by whatever would reestablish the normal tuplet look is
likely to work.

As usually, your guess is right and very helpful. That works perfectly:
\once \override TupletNumber.stencil = #ly:tuplet-number::print

Thanks also for all other replies to my question.

Hi Andrew,

thanks, but I wonder why do you use a #point-stencil instead of ##f –
which would be equivalent to my \omit version (if I understand things

what's wrong with \partial

[Jinsong Zhao]

Hi there,

The following snippet can't give correct output. It produced the 
following warnings:


warning: barcheck failed at: -1/4
\partial2 d4
 |

\version "2.19.26"
\relative c' {
\clef "treble"
\key g \major
\tempo 4 = 100
\numericTimeSignature
\time 3/4

\partial2 d4 |
g4 g g |
}

If \partial2 was replaced with r2, there is no warnings. However, I 
don't want the rest sign at the beginning of this piece.


I appreciate you for any suggestions.

Best regards,
Jinsong

Re: what's wrong with \partial

Hello Jinsong,

That’s because your barcheck is in the wrong spot. You have two 4’s in the 
upbeat.

\version "2.19.26"
\relative c' {
\clef "treble"
\key g \major
\tempo 4 = 100
\numericTimeSignature
\time 3/4

\partial 2 d4 g4 |
g g
}

Re: what's wrong with \partial

[bobr...@centrum.is]

Try this:

Change \partial 2 to \partial 4

"\partial 2" means that the first measure contains a half-note's worth of time. 
 It does *not* mean the first part of the measure you want to leave out.  You 
obviously want only one quarter note in the partial measure so you need 
'\partial 4'.

You probably mean

\partial expect a duration (of the partial). You have it inversed.

Sometimes, e.g. with NoteHeads IIRC, it causes problems if you have no 
stencil at all. That’s what a point-stencil is useful for – it’s 
invisible and has no extent, but it provides a reference point.

However in this case I don’t think it would be necessary.

Setting it to #f was causing fatal crashes in Fedora 22 until the amazing 
developers got it fixed. Using #point-stencil was found to avoid the problem.

Style question for bar checks

[Noeck]

Hi,

this is a question of ly code style:
Would you recommend putting the bar check always after the note or in
some circumstances also after an including brace?

Background: In many cases it is wrong to put a bar check outside braces
because it is then outside the music expression and appears as its own
music expression. Like:

  \alternative {
{ a2 b } |  % wrong
{ a2 a } |  % wrong
  }

This makes me think one should perhaps always write `a | }`
instead of `a } |` – but how about this case?

  a2 \tuplet 3/2 { a4 a a } |

Would anyone prefer this?

  a2 \tuplet 3/2 { a4 a a | }

Cheers,
Joram

If there is more than one measure in each alternative sequence,
then the | go inside each the {} for each sequence.
If each alternative sequence is shorter than one measure, 
the | has to go outside the entire \alternative {{} {}} |

Alternatives that fit exactly one measure could be written either way.
I prefer a single | outside the \alternative

The tuplet is less than a measure long, so the | makes more sense outside.

I make fewer mistakes when I use Michael Hendry's style

shapeII (openlilylib) with v2.19.25

[Simon Albrecht]

Hello,

I have a problem with \shapeII (from openlilylib; in the override-like 
form) using v2.19.25. The following snippet:


\version "2.19.25"
\include "notation-snippets/shaping-bezier-curves/shapeII.ily"

{
  \shapeII #'((0 . 2)) #'(Slur)
  c''( b)
}


has been working up to v2.19.23, but with .25 I get

/tmp/frescobaldi-5ZX7nT/tmpQSaLj0/test-shapeII.ly:5:3 <0>: error: wrong 
type for argument 3. Expecting music, found (list (quote Slur))


\shapeII #'((0 . 2)) #'(Slur)

/tmp/frescobaldi-5ZX7nT/tmpQSaLj0/test-shapeII.ly:5:3 <1>: error: error 
in #{ ... #}


\shapeII #'((0 . 2)) #'(Slur)


and the override has no effect.
The problem does not lie with the symbol-list-or-music? predicate in 
itself, as I might have suspected (but of course such a defect would 
have shown up much earlier), and I don’t know where to search for the 
problem.

You are cheating with your question because you are omitting relevant
context.  If this is part of

   \alternative { a2 \tuplet 3/2 { a4 a a | } }

then you are obviously asking for trouble by moving | outside.  As a
rule of thumb, if the final | would be the first to occur at its level
at all, I lean towards moving it outside.

Both are exactly equivalent. I only accidentally pasted the #'(Slur) 
version which I had also used in testing – it doesn’t change the problem 
either way. Normally I write Slur, of course.

\tweak no longer accepts a symbol/symbol-list as its last argument and
needs to get replaced with \propertyTweak when used in that facility.

Simon,

please create an ossue on GitHub with this information.
Should be updated with a version switch.

Or the calling code just splits between \tweak/\override based on
argument type.  Then you don't need a version switch.

Done. I included the new file in the issue.

Hello,

I have a problem with \shapeII (from openlilylib; in the override-like
form) using v2.19.25. The following snippet:

\version "2.19.25"
\include "notation-snippets/shaping-bezier-curves/shapeII.ily"

{
   \shapeII #'((0 . 2)) #'(Slur)
   c''( b)
}


has been working up to v2.19.23, but with .25 I get

/tmp/frescobaldi-5ZX7nT/tmpQSaLj0/test-shapeII.ly:5:3 <0>: error:
wrong type for argument 3. Expecting music, found (list (quote Slur))

\shapeII #'((0 . 2)) #'(Slur)

/tmp/frescobaldi-5ZX7nT/tmpQSaLj0/test-shapeII.ly:5:3 <1>: error:
error in #{ ... #}

\shapeII #'((0 . 2)) #'(Slur)


and the override has no effect.
The problem does not lie with the symbol-list-or-music? predicate in
itself, as I might have suspected (but of course such a defect would
have shown up much earlier), and I don’t know where to search for the
problem.

\tweak no longer accepts a symbol/symbol-list as its last argument and
needs to get replaced with \propertyTweak when used in that facility.


Thanks, that did it.
Yours, Simon
