Automatic cross-staff chords - testing help

[Davide Bonetti]

Hi,

Great work.

I've done some testing and found some bugs. Below the code I've tested, 
attached the PDF with the result (on second page, first page are your 
examples).

\autoSplitChord doesn't works with curly braces, it returns blank output 
(like a blank space in the score), so it's not possible to work with:
- chordmode
- more than one chord a time
- moltiple voices

Also, \autoSplitChord doesn't works with single notes, it returns blank 
space.

It accepts variables, but the result is the same.

Pippo = <c e g c' e'>1
PippoDue = \chordmode {c1:/g}
PippoTre = c1
PippoQuattro = {<c e g>}

\new PianoStaff
\with { \consists #Span_stem_engraver }
<<
  \new Staff = "up"
  {
    \key c\major
    %chord with stem up
    \autoSplitChord #UP <f a a' f'>2         %works
    %chord without stem
    \autoSplitChord <g c' e'>4            %works
    %chord with stem down
    \autoSplitChord #DOWN <g c' e'>        %works
    %chord, whole note
    \autoSplitChord <c g e' c''>1        %works
    %chordmode
    \autoSplitChord \chordmode {c:/g}         %blank output
    %chord entered in curly braces
    \autoSplitChord {<c g e' c''>}         %blank output
    %more than one chord, in curly braces
    \autoSplitChord {<c e g> <d     f a>}  %blank output
    %single note
    \autoSplitChord c                 %blank output
    %single note in a chord
    \autoSplitChord <c'>            %works
    %chord entered in polyphonic style
    \autoSplitChord <<c\\e'\\g''\\g,>>        %works
    %polyphonic style, different durations
    \autoSplitChord <<c1\\e'2\\g''\\g,>>    %warning & strange output
    %polyphonic style, with some curly braces
    \autoSplitChord <<c1 \\ {e2 f}\\d'1>>    %notes in curly braces are 
not printed
    %polyphonic style, with curly braces
    \autoSplitChord <<
      {c4 d e f}
      \\
      {c' d' e' f'}
    >>                        %blank output
    %chord in a variable
    \autoSplitChord \Pippo            %works
    %chord in a variable with chordmode
    \autoSplitChord \PippoDue            %blank output
    %single note in a variable
    \autoSplitChord \PippoTre            %blank output
    %chord in curly braces in a variable
    \autoSplitChord \PippoQuattro        %blank output
  }
  \new Staff = "down"
  {
    \key c\major
    \clef bass
    s1
  }
>>

Thank you for the work.

Cheers

Davide
