As a demonstration of the bleed-over between files processed on the
command line, the following file (let's say named
`frameEngraver4test.ly') will process without error if run with
'frameEngraver4.ly' on the command line:
lilypond frameEngraver4 frameEngraver4test.ly
The file:
\version "2.17.6"
frameStart =
#(make-span-event 'FrameEvent START)
frameEnd =
#(make-span-event 'FrameEvent STOP)
\relative c'' {
\override Stem #'transparent = ##t
\override Beam #'transparent = ##t
\once \override Frame #'extender-length = #8
\frameStart dis'8[ e f \frameEnd ges] s2
\once \override Frame #'extender-length = #11
\frameStart d,8[ e f \frameEnd g] s2
\once \override Staff.BarLine #'X-extent = #'(+inf.0 . -inf.0) %
line can cross bar line
s2
\once \override Frame #'extender-length = #3.5
\frameStart fis'8[ bes,, aes, \frameEnd e'']
}
\layout {
\context {
\Global
\grobdescriptions #my-grob-descriptions
#my-event-classes
}
\context {

\consists \frameEngraver
}
}
