You could do:
\version "2.19.65"
\score {
{
r2 r
\break
\bar "S"
R1
\bar "|."
}
\layout {
\context {
\Staff
\consists
#(make-engraver
((stop-translation-timestep engraver)
(format #t "\nwhichBar: ~a"
(ly:context-property
(ly:translator-context engraver)
'whichBar)))
(acknowledgers
((bar-line-interface engraver grob source-engraver)
(ly:grob-set-property! grob 'after-line-breaking
(lambda (grob)
(format #t "\nglyph: ~a"
(ly:grob-property grob 'glyph))
(format #t "\nglyph-name: ~a"
(ly:grob-property grob 'glyph-name)))))))
}
}
}
Note the difference for the grob-properties, due to line-break.
Cheers,
Harm
