Hi Urs,

The NR (1.2.3 "Displaying Rhythms") states that time signatures "are printed at the beginning of a piece and whenever the time signature changes."

But if I write

music = {
  \time 3/4
  R2.*4
  \time 3/4
  R2.
}

the time signature is printed a second time although it doesn't change (to my understanding)

a) Is this intended behaviour? And if yes, shouldn't it be documented?

I would think that you should need to tell LilyPond to force the unusual situation of a redundant time signature as it's not typical practice.  It shouldn't be possible to do something unusual like this through oversight.

OK, I see.

 

b) How can I achieve that the time signature is only printed if it is actually different from the one currently in use?

This question came up here:

Hopefully the engraver (see second version) still works!

Yes, it works with 2.16 and 2.17.17.

Thank you very much!

c) How can I achieve the same (only displaying if really changed) for key signatures and clefs?

Possibly that engraver can be adapted.  (I can't try now as my job is calling).

Although I've done my first steps with Scheme by now I don't see any chance to try that myself. So I'd be extremely grateful if you could give it a try.

This will surely become part of openLilyLib, and I think it should also be included in LilyPond proper (because this 'uncommon' behaviour should be possible, I think (Trevor even thought it were a bug, isn't it))
