dur serves as a placeholder for an argument. You should find it again in
the explanatory text on the function, which is sometimes very short. In
fact, the argument referenced here as dur is of type ly:duration? - that's
the data type. Durations may be created through the scheme function
ly:make-duration.

Re: scheme problem: colored background, layers
Hi Pierre,
thanks for taking the time to think about it.
Meanwhile, after some sleepless nights ;-) I've found another way to
get some results:
% ---
\version 2.18.0
colorSpan =
#(define-music-function (parser location y-lower y-upper color) (number?
number? color?)
#{
\override Staff.HorizontalBracket #'stencil =

(let* (
(area (ly:horizontal-bracket::print grob))
(X-ext (ly:stencil-extent area X))
(Y-ext (ly:stencil-extent area Y))
)
(set! Y-ext (cons y-lower y-upper)
)
(ly:grob-set-property! grob 'layer -10)
(ly:make-stencil (list 'color color
(ly:stencil-expr (ly:round-filled-box X-ext Y-ext 0))
X-ext Y-ext))
))
#})
{

\colorSpan #0 #5 #(rgb-color 0.5 1.0 0.5)
r4\startGroup r \stopGroup
\colorSpan #-5 #0 #(rgb-color 0.9 1.0 0.5) r\startGroup r\stopGroup }
\\
{
\override Voice.ClusterSpanner.color = #(rgb-color 0.5 0.6 1)
\override Voice.ClusterSpanner.layer = #-1
\makeClusters { s1 c'2 g' c' s s1 }
}
}
\layout {
\context {
\Voice
\consists Horizontal_bracket_engraver
\override HorizontalBracket #'thickness = #0
\override HorizontalBracket #'bracket-flare = #'(0 . 0)
\override HorizontalBracket #'Y-extent = #'(0 . 0)
\override HorizontalBracket #'edge-height = #'(0 . 0)
\override HorizontalBracket #'Y-offset = #0
\override HorizontalBracket #'shorten-pair = #'(-1 . -0.75)
}
}
% ---
Result:
http://4.bp.blogspot.com/-THmAQWfqDaw/VHztoaE6N2I/ACs/9Sqgl4ViMBc/s1600/ly-ex3.gif
This time, I abused the Horizontal_bracket_engraver that is used for
\startGroup and \stopGroup and replaced it's stencil by a rectangle.
Because it's not attached to the StaffSymbol, it can be placed in a
different layer, so the blue cluster and the staff lines both stay visible.
Anyway, LilyPond does the horizontal spacing without the need for manual
work.
This might make life easier for doing crazy things like this:

mailto:benbigno...@gmx.de:
thanks for your reply.
Unfortunately, changing the layer value from -10 to -2 doesn't
help. The problem is that the function places the staff lines and
the colored rectangle into the *same* layer, whereas I need to
leave the staff lines in layer 0 and put the rectangle into layer
-2 (or even less).
This would allow me to put other clusters *between* them like in
the first example.
Right ! Now I see the problem, 'seems that I've replied without
thinking...
I have already found another interesting snippet:
http://lsr.di.unimi.it/LSR/Item?id=953
But in that case, I would have to find the dimensions for the
rectangle by trial-and-error, whereas overriding the StaffSymbol
seems to be a very easy way...
Actually I've made this one (which is more or less a draft). I'll try
to see what I can do with it. No promise though :(
Cheers,
Pierre

Hi,

Here is my problem:
Now the staff lines and the yellow rectangle are located in the same
layer, so it's not possible to place the blue cluster between them.
Is there a way to make the scheme function put the staff lines
(StaffSymbol) and the yellow rectangle into different layers?
How about changing the layer value from -10 to -2 ?

Re: scheme problem: colored background, layers
Salut Pierre,
thanks for your reply.
Unfortunately, changing the layer value from -10 to -2 doesn't help. The
problem is that the function places the staff lines and the colored
rectangle into the *same* layer, whereas I need to leave the staff lines
in layer 0 and put the rectangle into layer -2 (or even less).
This would allow me to put other clusters *between* them like in the
first example.
I have already found another interesting snippet:
http://lsr.di.unimi.it/LSR/Item?id=953
But in that case, I would have to find the dimensions for the rectangle
by trial-and-error, whereas overriding the StaffSymbol seems to be a
very easy way...
Cordialement,
Klaus Blum

mailto:benbigno...@gmx.de:
Here is my problem:
Now the staff lines and the yellow rectangle are located in the
same layer, so it's not possible to place the blue cluster between
them.
Is there a way to make the scheme function put the staff lines
(StaffSymbol) and the yellow rectangle into different layers?
How about changing the layer value from -10 to -2 ?
bgColor =
#(define-music-function (parser location y-lower y-upper color)
(number? number? string?)

\override Staff.StaffSymbol.stencil =
$(lambda (grob)
(let* ((staff (ly:staff-symbol::print grob))

(Y-ext (ly:stencil-extent staff Y)))
(set! Y-ext (cons
(- (car Y-ext) y-lower)
(+ (cdr Y-ext) y-upper)))
;; change layer's value to -2
(ly:grob-set-property! grob 'layer -2)
(ly:stencil-add

Re: Scheme Problem
The reason that
#{
...
\repeat unfold $beats { r4 }
...
#}
doesn't work is the same that the following doesn't work in an
ordinary .ly file:
numberOfRepeats = 3
...
\repeat unfold \numberOfRepeats {...}
...
In other words, the argument of \repeat cannot be specified
using a variable in the current implementation of LilyPond.

Hi Brett,
Just a thought - the normal syntax for \repeat is
\repeat unfold 9 { music statements }
in your declaration you've put the keyword in quotes. Does it help if you
remove them? E.g.
compFor = #(define-music-function (parser location beats) (number?)
#{
\override Rest #'stencil =
#ly:percent-repeat-item-interface::beat-slash
\override Rest #'thickness = #'0.48
\override Rest #'slope = #'1.7
\repeat unfold $beats { r4 }
\revert Rest #'stencil
#})
I don't know any of the Lilypond or Scheme internals but there's a chance
that this could be confusing a parser or lexical analyzer somewhere along
the line. Software diagnostic messages are sometimes just an opener for
negotiation...

Can someone point out to me where I'm going wrong?

I don't know the exact reason but somehow the expansion into a scheme
construct doesn't work for variables in the \repeat unfold construct
(the parser expects a number but obviously doesn't resolve the $beats
before seeing it).
You can get it done this way: Look at the expansion of your function
with \displayMusic after replacing the variable with a real number (to
avoid the error) and then use the output of lilypond for defining your
music-function:
compFor = #(define-music-function (parser location beats) (number?)
#{
\override Rest #'stencil =
#ly:percent-repeat-item-interface::beat-slash
\override Rest #'thickness = #'0.48
\override Rest #'slope = #'1.7
\repeat unfold 16 { r4 }
\revert Rest #'stencil
#})
\displayMusic
\compFor #16
---
In the output of lilypond, you replace the 16 with the variable name
beats and copy that into the definition of your music function. It's
not really convenient and there's probably another way to get it done,
but at least it works.
