Re: Winged repeat bar line unique over multiple staves

[Alexis Maleval]

Thank you Simon.

Thomas,
your solution works very well too and it’s seems easier to use.
Thank you very much for your help.

Best regards,
Alexis.

Re: Winged repeat bar line unique over multiple staves

Hi Alexis, 

Schneidy has created a snippet for that issue:
http://lsr.di.unimi.it/LSR/Item?id=991

There's a little drawback: You have to (manually) adjust the bracket height
to match the staff group height. 
I've tried a little modification to avoid this: You can add the wings to the
topmost and lowermost staff in the group:

Probably this isn’t possible yet;


Yep. I rewrote the bar line stuff some years ago and stumbled across the 
fact that winged span bars are not possible.


I did not find an easy way to implement them, so I gave up :(

To be honest, the whole span bar creation routine is not really open for 
enhancements IIRC.

Oh.  But that's all single-staff.  And single-staff _does_ work in a
straightforward manner already like Alexis showed.

Meanwhile the bar-line-interface was heavily changed.
Making this old code compile with recent lily-version would mean to
entirely rewrite it.

Lemme think a bit more about the problem. In the past I tried
different methods to solve it, none of it convincing.
But maybe I'll get a better or at least new idea soon ...

Btw, please don't use inline images, attach them.  I'm not the only
one always filtering them/reading mails text-only.

Thanks,

Re: Winged repeat bar line unique over multiple staves

Hi,
I would like to know how to prevent a winged repeat bar line to be split when it
has to cover 2 staves.


Probably this isn’t possible yet; a BarLine is put together from the bar 
lines of every single staff plus the SpanBars between the staves. So I 
think one would need the following things:


1. Not only thick bar line with and without wings but also thick bar 
lines with only one wing (top or bottom).

2. A possibility to find out which of these is needed for each staff.
3. Compatibility with \defineBarLine.

Here some code which doesn’t solve your problem but shows 1. the use of 
\defineBarLine and 2. shows the difference between BarLines and SpanBars 
(colors).


%

\version "2.19.38"

\defineBarLine "[|:" #'("|" "[|:" ".|")
\defineBarLine ":|]" #'(":|]" "" " |.")
\defineBarLine ":|][|:" #'(":|]" "[|:" " |..|")

\layout {
  \context {
\Score
startRepeatType = #"[|:"
endRepeatType = #":|]"
doubleRepeatType = #":|][|:"
\override SpanBar.color = #blue
\override BarLine.color = #red
  }
}

\new StaffGroup <<
  \new Staff \relative {
c'1 \repeat volta 2 c \repeat volta 2 c c
  }
  \new Staff \relative {
c'1 \repeat volta 2 c \repeat volta 2 c c
  }
