[Denemo-devel] Typeset view has "Check Score" on it

[Richard Shann]

When the typeset score shows "Check Score" watermarked onto it the score
often prints ok, and you can be left wondering what is wrong.

 A new feature (since the last release I think) is that it is now worth
your while on Windows getting up the LilyPond window and right clicking
and choosing Typeset. You then get the error message *and* red
highlighting from the point where the error occurs. So you scroll down
until you find the red.
In a case I was sent recently there are two voices but the Voice
One/Voice Two settings are placed just before the notes start, leaving
the rests without any indication of which voice they belong to. It gives
the error where the rest occurs before the voice one/two marking
The message is:

/tmp/Denemowshnyl/denemoprintB.ly:888:10: warning: cannot resolve rest
collision: rest direction not set
         
         r<>  \mf \voiceOne <> ^\markup {"div. nat." } e'8-\accent \cr
r8 g'-\accent\AutoBarline
/tmp/Denemowshnyl/denemoprintB.ly:888:10: warning: cannot resolve rest
collision: rest direction not set


which is pretty techie, but the gist is that the rests in the two voices
are colliding because you haven't "set the rest direction", meaning (I
think) that you haven't said one rest is in voice one and the other in
voice two.

It still prints something, but all you need to do is move the Voice
One/Two settings before the rests and all is well.
