Hi David et al.,

What’s the current status on “measure-attached spanners”?
<http://lists.gnu.org/archive/html/lilypond-user/2013-12/msg01032.html>

I haven't been able to look at this, unfortunately.

Now it's possible to come up with a rudimentary grob, but doing this right seems like it would be quite a task, since there will be all sorts of complications like

--Should this be an enhancement of TextSpanner, or a new grob? (The latter would be easier, I would think.)

--The ability to break the spanner line to accommodate the text, with tweakable surrounding space

--Situations like ri -- tar --- dan --- do (which we really should support with TextSpanners)

--Ability to center text on the "musical" space (discounting prefatory material like meter and key signature) or between barlines..

--What to do with such spanners broken across lines.

This would be a great capability to have, of course, and I've thought about it recently.  (I have to make chord-spelling exercises with centered Roman numerals, and I don't like using the extra-offset trick I've been using.)

And I'd love to work on it, too, but time is limited and I can't offer more than "maybe sometime" :(
