Re: parenthesizing arpeggios

[David Nalesnik]

Hi again!

Here's something that works for arpeggios.  The attached file is a bit large because I needed to include several functions from stencil.scm to draw the parentheses.

Oh, what ever was I thinking!  No need at all for all that duplicated code...

This is all you need:

\version "2.15.36"

\relative c' {

  \override Arpeggio #'stencil = #(lambda (grob)

    (parenthesize-stencil (ly:arpeggio::print grob) 0.1 0.5 0.5 0.2))

  \override Arpeggio #'before-line-breaking = #(lambda (grob)

    (set! (ly:grob-property grob 'X-extent)

          (ly:stencil-extent (ly:grob-property grob 'stencil) X)))

  \repeat unfold 4 {

  <c g' e'>-\arpeggio

  } 

  <cis dis fis gis cis dis gis>-\arpeggio

  <cis dis fis gis cis dis>-\arpeggio

  <cis dis fis gis cis>-\arpeggio

  <cis dis fis gis>-\arpeggio

}
