Re: Note duration line (contemporary)

[Jeffrey Trevino]

Hi all,

It's good to know how to do this. For metric notation, I found that it's also useful to stop the duration line before the barline, instead of continuing it to a subsequent notehead, if the following note is in the next bar:

#(define flat-gliss
  (lambda (grob)
    (let ((left-Y (assoc-get 'Y (ly:grob-property grob 'left-bound-info))))
      (ly:grob-set-nested-property! grob '(right-bound-info Y) left-Y))))

\relative c'' {
  \override Glissando #'after-line-breaking = #flat-gliss
  \override Glissando #'thickness = #8
  \override Glissando #'to-barline = ##t
  c1\glissando
  g'\glissando
  g,
}

There's one more important tweak, remaining, though, and I can't figure it out: Is there a way to make the ends of the lines square instead of round? I don't see a property for this in line-interface.

best,
Jeff

I didn't get anything to work using an override of  #'bound-details
#'right #'Y, but you can override 'after-line-breaking like so:

\version "2.17.7"

#(define flat-gliss
  (lambda (grob)
    (let ((left-Y (assoc-get 'Y (ly:grob-property grob 'left-bound-info))))
      (ly:grob-set-nested-property! grob '(right-bound-info Y) left-Y))))

\relative c'' {
  \override Glissando #'after-line-breaking = #flat-gliss
  \override Glissando #'thickness = #5
  c1\glissando
  g'\glissando
  g,
}

HTH,
David
