Well, up to now unpure-pure containers are the most cryptic and ununderstood topic for me. Over the years I tried to understand them again and again, with little success. After your hint above I looked through our docs again. I found: NR 5.5.6 unpure-pure containers http://www.lilypond.org/doc/v2.19/Documentation/notation/unpure_002dpure-containers unpure-pure-container.ly in /input/regression CG 10.13 Understanding pure properties http://www.lilypond.org/doc/v2.19/Documentation/contributor/understanding-pure-properties I have to say the documentation became better over the years in the sense of being more verbose and yes, this is an advantage. But it lacks of examples. The one in the NR works with _and_ without unpure-pure-container. So the only compilable and working example (i.e. where unpure-pure-container make the difference) is the one from the reg-tests. Furthermore, almost always the topic is overriding directly Y-offset/extent or properties affecting those. Ok, setting OttavaBracket.text may affect Y-spacing, though I've no idea idea how to do it with a unpure-pure-container. May I ask you how to do it with this code-example? { \override Staff.OttavaBracket.after-line-breaking = #(lambda (grob) (ly:grob-set-property! grob 'text "foo")) \ottava #1 c''4 4 4 4 4 4 \ottava #0 4 4 \break \ottava #1 c''4 4 4 4 4 4 \ottava #0 4 4 \break \ottava #1 c''4 4 4 4 \break 4 4 \ottava #0 4 4 } Cheers, Harm _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
