Hello Harm,

Thanks for your help and thanks a lot to David for supplying this useful Scheme code. I’ll use that for sure!

I’ve nearly reached my goal. Further attempts lead me to the following, using a GrandStaff and:

       \override GrandStaff.SpanBar.glyph-name = "|"
       \override Staff.BarLine.glyph-name = "'"

I can’t obtain a vertical short line at the left and right ends of the spanner yet though, since:

       \override AccordionPushSpanner.bound-details.left.text =
               \markup { \draw-line #'(0 . -3) }
       \override AccordionPushSpanner.bound-details.right.text =
               \markup { \draw-line #'(0 . 3) }

don’t make a change. That would be useful it seems.

Also, the thick parts of the repeat barlines don’t go down to the lower stave, but that is maybe less useful. Maybe diatonic accordion players on this list can comment on that. For the others, let’s mention that a thick line means « push » and that its absence means « draw ».

The next important step will be to convert the actual note pitches into the fingerings that should be displayed instead.

Hello folks,

I've modified the AccordionPushSpanner example supplied by someone on this list (can't find who it was, unfortunately), giving the attached file and the score :

How can I tune the settings to align the bar lines lower tips with the single staff line, and hide the dots in the repeat bar lines, in a way similar to:

<Diatonic look.png>
The small vertical lines would be nice to have too.

Thanks for your help!




the original coding is by David Nalesnik

Attached you'll find a revised version and an example. I recommend to
read the changelog in accordion.ily

To adjust the BarLines I'd simply set bar-extent to '(0 . 0) in the lower Staff.
