My apologies to all on the list for wasting bandwidth.  I eventually
stumbled on the answer to my question, which is to use
\override Rest.staff-position = 6
and
\override MultiMeasureRest.staff-position = 6
or similar.

The relevant variable is hidden away in the Internals Reference under
"staff-symbol-referencer-interface".  I confess that, although I had
looked at the lists of variables under the all the other interfaces
listed at the bottom of the IR pages for Rest etc., I hadn't looked at
this one because the name is so unpromising.

Yet I now find that the only variable listed there is the very one I
wanted!

Vertical position of rests in DrumVoice

[David Sumbler]

I am having difficulty controlling the vertical postioning of rests in
a DrumStaff which has several DrumVoices representing different
instruments.

The easy method of using a note-name followed by '\rest' doesn't seem
to work in a DrumStaff.  I have tried, for instance, 'sn8\rest', but
this produces a syntax error.

The other method I tried is overriding Rest.voiced-position and
MultiMeasureRest.voiced-position in the relevant Voice context, but
this seems to work inconsistently - something else is overriding it. 
And in the case of the MultiMeasureRest nothing I do will move a whole-
bar rest below the bottom line of the staff, even though in the same
voice minim rests are being placed one or two lines below the staff by
Lilypond itself.

How do I take full control of the vertical positioning of these rests?

David

Harm,


a walk-through: [...]


Trivial as it may seem to the more experienced LilyPond hackers, this 
might be a candidate for inclusion in the documentation! Especially the 
repeated application of the "display what's on hand" trick is enormously 
helpful, I think. Thank you!

Hi Joram,

a walk-through:

(1) Create code example:

{ r2 r1 }

(2) Initiate a most simple override

a) Try to go for the desired property directly, i.e. \override
Rest.staff-position = ...
b) Set it to a procedure, i.e. \override Rest.staff-position =
#(lambda (grob) ...)
Probably let the grob be displayed in terminal to ensure adressing the
correct one, i.e.:
{
  \override Rest.staff-position = #(lambda (grob) (display grob))
  r2 r1
}

(3) Get the duration
Here the 'duration-log will be enough, let it display to ensure corrrect coding

{
  \override Rest.staff-position =
  #(lambda (grob)
(let ((dur (ly:grob-property grob 'duration-log)))
(newline)
(display dur)))
  r2 r1
}

(4) Add a condition relying on the value of duration-log and provide
appropriate values for 'staff-position

{
\override Rest.staff-position =
#(lambda (grob)
  (let ((dur (ly:grob-property grob 'duration-log)))
(if (= 0 dur)
6
-6)))
r2 r1
}

Ofcours 6, -6 are not really appropriate values ...

This works quite well! I've made some quick tests and the scores are looking
much better (I am algorithmically adjusting the value of the
NoteColumn.X-offset depending on the size of the beamed group). I will make
some more tests, but it looks like this solves my issue. Many thanks!

Hi Gilberto,

I played around with the SpacingSpanner and
proportionalNotationDuration but to no convincing avail.

Best I can think of is:

{
  \override Staff.Stem.stemlet-length = #1.25
  c'16[ d'
  \once\override NoteColumn.X-offset = 1
  r deses']
}

Perhaps someone else comes up with a better method...

Position of rests inside beamed groups

[Gilberto Agostinho]

Hello all,

I am writing a composition in which all rests inside beamed groups have
stemlets. The problem is that because of my use of accidentals on every
single note and because spacing is sometimes a bit critical, there is very
little space between the rests's stemlets and the previous regular stem:

 

I thought of using Rest.X-extent to solve this, but the problem is that I
only need to increase the X-extent on the left side of rests and
unfortunately the stemlet position is always calculated as the half point
between two other stems. See:

\version "2.19.53"
{
  \override Staff.Stem.stemlet-length = #1.25
  c'16[ d' r f'] 
  \override Rest.X-extent = #'(-3.0 . 1.0)
  c'16[ d' r f'] 
}

 

Would anyone have some advice on how to better tackle this?

Many thanks!
Gilberto

Hi Peter,

Are you using \cueDuring? If so, you can change #direction to #UP or 
#DOWN, which places the small cue notes either above or below the rests. 
See 
http://lilypond.org/doc/v2.18/Documentation/notation/writing-parts#formatting-cue-notes


If not, perhaps you could provide a minimal example? See 
http://www.lilypond.org/tiny-examples.html

Greg.

Re: Vertical position of rests on a custom staff

[Paul Morris]

To conclude the saga...  Thanks to David Kastrup's tip my function can now 
automatically position all rests and their dots where they need to be, no 
matter what voice they are in.  Once again LilyPond can handle just about 
anything.  See attached file.

I'm now curious about the difference between using ly:grob-property-data and 
ly:grob-property.   The docs say:

  Function: ly:grob-property grob sym val
  Return the value for property sym of grob. If no value is found, return val 
or '() if val is not specified. 

  Function: ly:grob-property-data grob sym
  Return the value for property sym of grob, but do not process callbacks.

http://www.lilypond.org/doc/v2.16/Documentation/internals/scheme-functions

I assume this means that if a property is set to a function rather than a 
static value, then ly:grob-property would process the function to return a 
value, but ly:grob-property-data would not.  Is that right?  

Thanks again,

Yes.  For things like stem directions, there may be a default callback
which makes the decision about whether to put the stem upwards or
downwards, and calling this fallback might trigger other typesetting
decisions prematurely.  Also, one does not get to see whether the
ultimate direction decision was due to \voiceOne or such a tie-breaking
callback.

This may or may not be the case for rest direction, but because I was
too lazy to double-check, I went for ly:grob-property-data.

Ok, good to know.  It sounds like if ly:grob-property-data works for a given
case, then it's the safer choice of the two.  Thanks for the explanation.

Well, depends on what kind of data one tries testing for.

Re: Vertical position of rests on a custom staff

[Paul Morris]

Hi Pierre,  I tried your suggestion:

 restmusic =   \relative f {
   \override Rest #'Y-offset = #0
   \cadenzaOn
   ...
 }

But it put the whole and half rests on a ledger line in the middle of the 
custom staff, which was not really what I wanted.  

I tried to figure out a way to globally override the rest positioning for 
different voices on the same staff -- something like this:
http://www.lilypond.org/doc/v2.16/Documentation/notation/changing-context-default-settings#changing-all-contexts-of-the-same-type

But it doesn't look like it's possible to specify, at the level of a custom 
staff context, that the rests in the 1st voice on this type of staff get 
positioned here, and those in the 2nd voice get positioned there, etc.

So I revised my function so it would let you manually turn off/on the custom 
rest positions when you have more than one voice on a staff (see attached 
files).

After getting that working I checked to see if anything changed between v. 2.16 
to 2.17.19  And I'm really glad to say that in 2.17.19 the positioning of the 
rests was almost exactly what I wanted by default!  The only ones that needed 
re-positioning were the rarer ones that were longer than a whole rest.  Also 
the dots on about half of the rests also still needed re-positioning.  

If I'd known this before I probably wouldn't have gone to the trouble of 
writing my function.  It seems like overkill now.  (A good reason to start 
using or at least testing with the dev version sooner in the future.)  At any 
rate, big thanks to all those working on improving LilyPond with each new 
version.

I revised my function for use with 2.17.19 -- see attached.  While it would be 
nice if you didn't have to manually turn the overrides on and off when there 
are more than one voice on a staff, at least now this is only needed for rests 
that are longer than a whole rest, which do not occur that often.

 can see this on the right hand side of the PDF.

 Any thoughts on how to work around this?

Make your function do different things depending on the value of
(ly:grob-property-data 'direction grob)

This will be +1 or -1 for \voiceOne and \voiceTwo (or their
equivalents), and something else (0 or a function) when in \oneVoice
mode.

  The only ones that needed re-positioning were the rarer ones
  that were longer than a whole rest.  Also the dots on about half of
  the rests also still needed re-positioning.
 
 Could you elaborate?

See the attached files.  This one makes it clearer than the previous one.  The 
red rests and blue dots are the ones my function has moved.  

The 3 longest rests are lower on the custom staff than I wanted, so my function 
moves them up to where they usually are on the standard staff, but then the 
dots became centered vertically on the longest two rests.  So my function moves 
those dots up where they usually appear.

Dots were also centered vertically on quarter, 8th, and 16th rests on the 
custom staff, so my function moves them up to their usual position.  

I also show some staves with different line patterns where the Y-offset of the 
rests is manually set to 0.  Sometimes the dots are centered on the rests, and 
sometimes they are in their usual position (half a staff space higher).  

This is odd since the dot position apparently depends on the staff line 
pattern.  I suppose that the dots might be centered by default on the rest and 
then be shifted up to avoid a line through the middle of the rest.  (However, 
on one of the staves they appear in their usual position even though there is 
no line to avoid.)

Vertical position of rests on a custom staff

[Paul Morris]

Hello everyone,  

I am working on adjusting the vertical position of rests on a custom staff and 
have run into a problem.  I basically want the rests to be positioned as they 
are on the standard staff, but in my custom staff there is no center line so 
the rests become oriented to the next line above that (except for whole rests 
which stay the same).  See the attached files.

adjustment then puts them in the wrong place.  You can see this on the right 
hand side of the PDF.

Any thoughts on how to work around this?  I'm away from email for a day or two, 
but wanted to go ahead and send this while I was working on it.

Hi Paul,

try this :

restmusic =   \relative f {
  \override Rest #'Y-offset = #0
  \cadenzaOn
  ...
}
