Re: Slur connecting fingering numbers

[Rachel Knight]

One more question on this snippet - I encountered a place in my score with two 
thumb slides in a row. When that happens, it is nice to have the fingering 
numbers in a line. I figured out how to move the fingering number, but the slur 
did not go with it. 

r8 c'\p-3[ \acciaccatura {
\override Fingering.font-size = #-5
df16-2 ef-1\glissando}
\once \override Fingering.extra-offset = #'(0 . 1.5)
df8-1]\glissando |
  \revert Fingering.font-size
  c-1 

Would it be possible to add a property to the code so that the slur stays with 
the fingering number when moved?
If not, how would I adjust the slur in this example?

Best,
Rachel

I now come up with the attached code.

It's now possible to preserve the default glissandi. Also,
"glissando-stubs" are printable.

Still not sure if it's suitable for our docs.
Apart from the user-interface, which is still terrible, a new
context-property is defined and used: fingerSlide (boolean)

Hi Werner,

currently the code hijacks Glissando. I.e. the default glissando is no
longer printable.
I don't feel such a workaround should be in the docs.

Though, I'd like to come to a behaviour where "Finger-glissandos" are
possible without disturbing default-glissando (between NoteHeads)
That would be a nice amendment for our docs, not only for the harp,
but for guitar, violin, etc

I'll have to find a way to create glissandos and select properly.

For the creation part I've found that I can add additional glissandos
with glissandoMap. See:

val = 0

{
  \override Glissando.after-line-breaking =
  #(lambda (grob)
(ly:grob-set-property! grob 'extra-offset (cons 0 val))
(set! val (1+ val)))

  \set glissandoMap = #'((0 . 0) (0 . 0))
  c'\glissando f'
}

Is it safe to rely on it, or is it rather bug-using?

Cheers,
  Harm

This will not happen very soon. The LSR runs 2.18.2, but the used
make-tie-stencil is a 2.19 feature.

Hi Rachel,

default LilyPond drops the glissando-stencil in very tight situations. See:

{
  \override Glissando.after-line-breaking =
#(lambda (grob) (write (ly:grob-property grob 'stencil)))
  \acciaccatura { e''16 f''\glissando }
  e''8
}

Terminal displays '()

Though, my procedure printing the bows relies on a stencil being
present. Thus nothing happens.
This dependance bugs me anyway, so I'll have another look in the evening.

For now you could lengthen the glissando with:

\override Glissando.springs-and-rods = #ly:spanner::set-spacing-rods
\override Glissando.minimum-length = 2 %% adjust  to taste.

  Harm

Hi, 
The slur looks great and I was able to implement it for regular notes (the E 
and D in the example below). In my example though, I need the slur to be 
between the two notes labeled with fingering “1.” The small notes are added as 
an acciaccatura, and when I added \glissando, nothing changed. Do I need to add 
something else?
