Re: Staff.connectArpeggios not connecting all arpeggios

[Mats Bengtsson]

I think you have misunderstood what the macro \arpeggioBracket does.
It doesn't draw an arpeggio itself, it just tells that all future
arpeggios should be drawn as brackets instead of squiggled lines.

Also, the macro only sets the arpeggio type in the current Voice
context, whereas if you set connectArpeggios, they will be drawn within 
the Staff context. The solution to this is to redefine the normal 
\arpeggioBracket macro (which is defined in ly/property-init.ly)
so that it does the setting at the Staff level. I have also added a new 
macro \arpeggioNormal that reverts to the default layout. Then, your 
example could look something like:

arpeggioBracket =
 \override Staff.Arpeggio #'stencil = #ly:arpeggio::brew-chord-bracket


arpeggioNormal = \revert Staff.Arpeggio #'stencil

varVoiceMelody = \relative c'' {
%1
\arpeggioBracket e4 \arpeggio \arpeggioNormal g\arpeggio 
\arpeggioBracket e\arpeggio  \arpeggioNormal e\arpeggio
|
%2
\arpeggioBracket e\arpeggio gs\arpeggio \arpeggioBracket e\arpeggio e\arpeggio
|
%3
e1\arpeggio
|
}

varVoiceInner = \relative c' {
\stemDown
%1
s4 <e g c>\arpeggio s <e g c>\arpeggio
|
%2
s4 <d b' d>\arpeggio s <e gs d' e>\arpeggio
|
%3
s1
|
}

varVoiceBass = \relative c'' {
%1
\arpeggioBracket c,2\arpeggio g2\arpeggio
|
%2
e2\arpeggio b'2\arpeggio
|
%3
e1\arpeggio
|
}

  \new Staff \with {
        \consists Span_arpeggio_engraver
  }
  {
     \set Staff.connectArpeggios = ##t
         \clef "treble"
          \key c \major
          \time 4/4
         <<
         \new Voice="voiceMelody" { \voiceOne \varVoiceMelody \oneVoice } \\
         \new Voice="voiceInner" { \voiceThree \stemNeutral \varVoiceInner
\oneVoice } \\
         \new Voice="voiceBass" { \voiceTwo \varVoiceBass \oneVoice }
         >>
         \oneVoice

  }


Of course, you could also redefine the \arpeggioBracket command to only 
do the setting \once.
