Re: Dotted notes

Hi,

today I'm too tired to work on anything complicated ...
Though, some remarks:

Please post some code. so that we can debug what's wrong and why.
The code was developed with 2.19.81 so at least the example works for me.

Really?
I still see a collision with

\paper {
  #(define fonts
    (set-global-fonts
      #:music "beethoven"
      #:brace "beethoven"
      #:factor (/ staff-height pt 20)))
}

{ d'16.. }

"Difficult" doesn't scare me, Au contraire. Anything else is boring :)

This code (\dotsAndDotColumnPadding) will most likely never been
implemented in the source.

Postprocessing a delivered stencil is a _method_ I sometimes use, when
no other method sounds doable.

What should be documented?
- get the stencil-expression
- do the wished modifications with appropriate procedures
- set 'stencil to a new stencil with this new stencil-expression and
appropriate extents
That's all :)

As said, it's a method. Of sort 'last resort' :)

Though, it would be nice to have some user-settable grob-properties :
Probably a padding-property to adjust the space between NoteColumn and
DotColumn and a dot-padding-property to adjust the space between the
dots themselves.


Cheers,
