Thanks, and sorry about the delay. Added as

I think it's probably just a limitation that needs to be documented:
tuplets must begin with a note or a rest. (I've had strange results
with \bar as well).
Your example also showed something odd with the beaming of 2/8
measures. (see attached) Carl, I believe it was you who worked on
beaming recently, does this look like the desired/intended default
behavior to you?
{
\time 2/8
c'8
c'8
\times 2/3 {
c'8
c'8
c'8
}
c'8
c'8
}
Cheers,
Valentin

Tempo / tuplet bracket bug
Hi,
The following snippet exhibits a bug in the form of contention between
metronome mark and tuplet instantiation:
%%% BEGIN TEMPO INSTANTIATION BUG %%%
\version "2.13.9"
\new Staff {
\time 2/8
\times 2/3 {
\tempo 8=52
c'8 (
c'8
c'8
}
\time 2/8
c'8
c'8 )
}
%%% END TEMPO INSTANTIATION BUG %%
The interpreter gives the following warnings:
GNU LilyPond 2.13.9
Processing `0329.ly'
Parsing...
Interpreting music...
programming error: stopped tuplet bracket has left nor right bound.
continuing, cross fingers
0329.ly:10:10: warning: unterminated slur
c'8
(
0329.ly:16:10: warning: cannot end slur
c'8
)
Preprocessing graphical objects...
Solving 1 page-breaking chunks...[1: 1 pages]
Drawing systems...
And the output is attached here as tuplet-bracket-bound-bug.png.
The problem apparently has to do with the lexical spot at which the tempo
mark instantiates. Moving the tempo mark prior to the tuplet \times command
provides a workaround:
%%% BEGIN WORKAROUND %%%
\version "2.13.9"
\new Staff {
\time 2/8
\tempo 8=52
\times 2/3 {
c'8 (
c'8
c'8
}
\time 2/8
c'8
c'8 )
}
%%% END WORKAROUND %%%
Note that what makes this one particularly slippery is that the output from
the buggy example (shown in the png attached here) is actually syntactically
wrong: the measure of 2/8 prints with three eighth notes (because the tuplet
bracket goes missing). The rhythmic inaccuracy is easy enough to spot in
this pared-down example; but in a situation of considerably more rhythmic
complexity this can be lethal. (In the realworld score that I am working on
that surfaced the bug it was, in fact, only the very visible absence of an
extended slur that made this one possible to find.)
Trevor.
