If you compare these regression test examples between
versions 2.6 and 2.7, you can notice that there is a difference.
I have just sent a bug report, asking if it's an intentional
change or a bug. What I described should at least hold in
version 2.6.

The old \turnOff macro had nothing to do with what you are asking about. Rather, the built-in rule is that you get a right edge of the bracket if it ends at a bar line that is
either a repeat or a double bar line (with one of the lines
thicker, i.e. \bar "|." or ".|"). Otherwise, the bracket
will be open ended.

Please include a small example from your score if you need more help from the mailing list.

Quoting Stan Sanderson <address@hidden>:

I posted this message this morning but have not seen it, so I am reposting.

Is is not yet possible to leave a volta bracket "open" (i.e., no descender on the right end)? The docs (Bugs) for 2.7.32 (PDF) report that

2.2->2.4:
\turnOff (used in \set Staff.VoltaBracket = \turnOff) is not properly converted.



Forgive me if I've missed it, but I couldn't find anything in regression tests or examples.


Thank you for the clarification.

The source file had originally been coded in v1.?, updated to an early v2.x and was now updated to 2.7.36. The error generated referred to the \turnOff macro.

There was a \bar "||" at the location in question. I removed it and it coded as you mentioned (although it is not a double bar line "...with one of the bars thicker.").

I spent some time looking at the documentation (current 2.7.36, from the tarball) and didn't find this property described. Probably missed it.

What is confusing is that there is an example in the Regression Tests titled "repeat-volta-skip-alternatives.ly" which appears to not follow the rule given above. The example which follows ("repeat-volta.ly") also shows a closed volta spanner at the end, although no barlines is present.

I found no examples in the "Tips and Tricks" section which might apply.

This is in no way criticism! I feel privileged to have had the opportunity to watch this Lily grow.

Stan
