When I was working on `The Phantom of the Opera' a few weeks ago,
I noticed that the brackets over alternative endings get misaligned
when the alternative is placed at the beginning of a line.
I used version 1.3.47 at that time. After upgrading to 1.3.52 and
doing some tests, I noticed that in this case:
1: The bracket for the first alternative starts *after* the clef and
time signature; brackets for the other alternatives start *before*
the clef.
2: The brackets at the beginning of a line are too short.
There should be a small gap (half the interline spacing) between
brackets.
I included a sample file which demonstrates the behaviour I described
above, as well as a suggestion for dealing with situation #2 (in the
hope that it won't break other things).
Sample file:
---------------
\header{
filename = "spantest.ly";
title = "Spanner test";
composer = "";
enteredby = "Johan Schoone";
}
$data = \notes \relative c' { \time 4/4; \key c \major;
\repeat "volta" 3 { c d e f g a b c b a g f e d c r
c e g c e, g c e g, c e g c, e g c c g e c g' e c g e' c g e c' g e c }
\alternative { { <c1 e1 g1 c1> } { <c2 e2 g2 c2> r } { c4 e g c } }
\repeat "volta" 3 { c, d e f g a b c b a g f e d c r
c e g c e, g c e g, c e g c, e g c c g e c g' e c g e' c g e c' g e c }
\alternative { { <c1 e1 g1 c1> } { <c2 e2 g2 c2> r } { c4 e g c } }
\repeat "volta" 3 { c, d e f g a b c b a g f e d c r
c e g c e, g c e g, c e g c, e g c c g e c g' e c g e' c g e c' g e c }
\alternative { { <c1 e1 g1 c1> } { <c2 e2 g2 c2> r } { c4 e g c } }
\repeat "volta" 3 { c, d e f g a b c b a g f e d c r
c e g c e, g c e g, c e g c, e g c c g e c g' e c g e' c g e c' g e c }
\alternative { { <c1 e1 g1 c1> } { <c2 e2 g2 c2> r } { c4 e g c } }
}
\score{
\context Staff { \$data }
\paper {
% linewidth = 18.0\cm;
% textheight = 27.0\cm;
}
}
