I'd be really grateful if someone can also point me to
where the documentation explains why removing the the Bar_engraver also
removes the Clefs.
I don't think that this is documented in the docs, but in the sources:
In lily/clef-engraver.cc:
85 /**
86 Generate a clef at the start of a measure. (when you see
a Bar,
87 ie. a breakpoint)
88 */
89 void
90 Clef_engraver::acknowledge_bar_line (Grob_info info)
91 {
92 Item *item = info.item ();
93 if (item && scm_is_string (get_property ("clefGlyph")))
94 create_clef ();
95 }
If there is not bar line to be acknowledged, the clef will not be
printed.
I don't know whether this is the desired behaviour as there are cases
where you need the clef and line breaks, but no bar lines.
HTH a bit,
Thanks, Marc - that does help. Even if I'd thought to look in the
sources I wouldn't have really grasped what that meant. For me, for this
purpose, it isn't the desired behaviour. I wonder if there's a good
reason for it? Anyway, at least now on the email list there's a note of
the behaviour if anyone searches for it in future,
So, to summarise - to remove bar lines and have automatic line breaking
but retain the clef at the new line you can't use
\context {Staff \remove Bar_engraver}
(.e.g in layout, for a group of scores) - instead, you need to use
\override Staff.BarLine.stencil = ##f
which has to go in each score, but for batch overriding you can add the
override to the score using a variable, which can of course be used for
other purposes as well.
-------------------
\version "2.18.0"
thistest = {
\override Staff.BarLine.stencil = ##f
}
\score {
\relative c'{
\thistest
\repeat unfold 40 { c1 }
}
\header {
piece = "Using variable override stencil keeps clef engraved with
automatic line breaks"
}
}
----------------------------------------------------------
HTH someone!
