Requested by Xavier Scheuer x.scheuer@gmail.com

This is by far the most popular enhancement request from the French
users mailing list: Bar numbering of repeat volta alternatives.

Currently LilyPond counts the measures of each "alternative" as
normal, unrepeated, measures hence incrementing the currentBarNumber
in both alternative "1." and "2.". Several references supports what is
actually asked by many users: bar numbering of alternatives should not
be counted twice.

\version "2.15.20"

\relative c' {
  \override Score.BarNumber #'break-visibility = #'#(#t #t #t)
  \repeat volta 2 {
    c1 |  % 1
    c1 |  % 2
    c1 |  % 3
  }
  \alternative {
    {
      c1 |  % currently: 4  % request: 4 or 4a
    }
    {
      c1 |  % currently: 5  % request: 4 or 4b !!
    }
  }
  \textLengthOn
  c1^"currently: 6  request: 5 !!" |  % currently: 6  % request: 5 !!
  \textLengthOff
  c1 |  % currently: 7  % request: 6
  % etc.
}

Please do not discard this (popular) request again.
I'd suggest to have at least the possibility to switch on this
feature, for example via a variable setting such as
\set barNumberAlternativeOnce = ##t

Well-know music publishing houses that use this numbering includes
Simrock, Breitkopf, Bärenreiter, Henle.

E.g. Henle et Breitkopf: |1. 34 | 35 :||2. 34 | 35 etc.,
Bärenreiter: |1. 34a | 35a :|| 2. 34b | 35b.

I do not know what say music engraving books like Ross, Read or Gould
but here is what says Jean-Pierre Coulon in his "Repository of
music-notation mistakes" or "Essay on the true art of music engraving":

"When first ending-second ending measures are present, measure numbers
of only the first ending measure act on the numbering. If necessary,
corresponding measure numbers have the subscripts a and b."

Section 5.4 page 9.

The implementation and what to do in the case of alternatives of
different measures duration are open to discussion.
But keep in mind that in 90% of the cases there are only 2 alternatives
which have the same measures duration. In the remaining cases
the first alternative is often the shortest.

Thanks for your attention.

Cheers,
Xavier (and many French users)

So I think this is ok.

Also does this imply some documentation - to show users how to use this feature (turn it on/off - whatever we decide the default is)?

If so can we have a new tracker and a simple example I can then stick in somewhere.

The display-lily-tests.log output is a showstopper. Without explicitly enabling this kind of functionality, we should not even be getting different music types.

And I totally don't like "RenvoiMusic" for indicating a different variant (?) of repeat alternatives. There is no reason whatsoever to introduce _French_ into our variable names when there is, as far as I know, no such French term in English music terminology (there is a host of Italian terms and the occasional German one).

Anyway, because of the showstopper, I am putting the patch status back to needs_work.

The use of this

\set Score.alternativeNumberingStyle = #'number

\set Score.alternativeNumberingStyle = #'numbers-with-letters

deserves an explanation (as a snippet) in the notation reference,
NR 1.4.1 Long repeats and maybe a cross-reference in NR 1.2.5 Bars >
Bar numbers

and this new feature deserves an entry in 'Documentation/changes.tely'
IMHO

Thank you!

This issue should be tagged as Fixed_2_15_21 (2_15_22 if you consider
the second commit) and someone could verify it, IMHO.
