Okay, traverse upwards with daddy_trans_l until I reach the Staff, I see.
My question was more like: How do I know when I reach the staff? I.e. Will the
following (untested) code be too slow - testing aliasses on all levels? It has
to be done for each and every accidental...
while ((!mytranslator.is_alias_b("Staff")) && mytranslator->daddy_trans_l_)
mycontext = mycontext->daddy_trans_l_;
The good thing about doing so, ofcourse, would be that we could allow for the
very nice and understandable accidental definitions a'la
\property Score.autoAccidentals = #'((measure-same-octave 0 Voice) (measure-
same-octave 0 Staff))
To typeset the union of the accidenals of the old engraver in voice context and
the old engraver in staff context.
I think I go for it and hope that it doesn't slow down lilypond too much.
