Hello list,
I am quite frustrated – yesterday I managed to get the shift out of
input/regression/beam-feather-breaking.ly which was one of the
last problematic files for my patch.
Today, I looked at the new results: it seems to me that
*every* other regtest file is affected now, but the one mentioned above
is missing – that's not what the patch is supposed to do.

(side note: I did not take a full test cycle, since the last
regtest results showed only major changes in a couple of files, most of them
were deliberate, and beam-feather-breaking.ly was the one with the biggest
optical difference, so I checked just this one and did a make all &&
make doc
afterwards, which went trough without complaining).
I double-checked the dimensions of the empty bar line: it is
(0.0 . 0.0) for the current master *and* my patch, so this cannot be
the culprit.
\version "2.17.4"
#(define (my-bar-line::print grob)
(let ((stencil (ly:bar-line::print grob)))
(for-each display (list "\n\nBar line extent:"
(ly:stencil-extent stencil X) " for bar line "
(ly:grob-property grob 'glyph-name)))
stencil))
music = {
\override Staff.BarLine #'stencil = #my-bar-line::print
c4 c c c \bar ""
c c c c \bar "|."
}
\score {
\new Staff {
\new Voice { \music }
}
}
Can anyone with more knowledge than me give me a hint what's wrong?
IIUC correctly, lilypond draws a bar line at the beginning of each line,
but in most cases, this is an invisible one.
If you look at the results of input/regression/lyrics-spanbar.ly,
the whole stuff is shifted that much to the right that lilypond moves
the rightmost rest to a new line! I can't believe that a bar line with
zero width can be the cause for this...
Any hints are highly appreciated!
Regards,
Marc
