No, unfortunately not at this time.  (If I remember correctly, there are
problems with the placement of the timing bracket.)

How would the code for that function look? I can't quite picture what you
mean.

Thanks!

In such a case you can

The attached file will let you do the aleatoric notation with repeat
barlines without resorting to wholesale copying (or adding things to the
end of scm\bar-line.scm).  The barlines have been recreated.  They are
scaleable.

There are now two options available with the same file: box notation, or
repeat-barline notation.  Boxes are the default.  You can select barlines
like so:

\override Frame.repeat-barlines = ##t

Both can be used in the same file, successively or simultaneously in
different staves.

Because it's so long, I've put the engraver in a file to be included.

HTH,
David

Again, I think the best course of action here is not to omit the frame;
rather, you would replace the frame with repeat-bar stencils.

The problem that I'm facing is that I can't find a convenient function in
the barline interface to produce a barline stencil.  It's possible to quote
massive portions of scm\bar-line.scm in the .ly file and then make some
adaptations to the print function for Frame and the width function for
FrameStub (see the latest version of the file at
http://www.mail-archive.com/lilypond-user@gnu.org/msg83197/frameEngraver25.ly).
That works, but it's just too awful.

Hi again. This time i'm trying to modify frameEngraver written by David 
Nalesnik (Big thanks). I'm using 2.16.2 version of LilyPond and 
frameEngraver8.ly, which you can find here:

http://lilypond.1069038.n5.nabble.com/attachment/139396/0/frameEngraver8.ly

So, what I'm trying to achieve is to replace the frame with repeat signs, so 
that you have:

|: music :|--->

This is so called indipendent repetition and it's very common in contemporary 
music.

I have no idea how to do this. Any Any ideas would be greatly appreciated...
