I'm writing my first JW Lua script, to put double barlines at key- and time-signature changes.

allmeasures = finale.FCMeasures()
allmeasures:LoadAll()
lastmeasure = finale.FCMeasure()
for measure in each(allmeasures) do
    if measure.ItemNo > 1 then
        if not measure.TimeSignature:IsIdentical(lastmeasure.TimeSignature)
        or not measure.KeySignature:IsIdentical(lastmeasure.KeySignature)
        then
            lastmeasure.Barline = finale.BARLINE_DOUBLE
            lastmeasure:Save()
        end
    end
    lastmeasure = measure
end


It's getting the error

[string "allmeasures = finale.FCMeasures() ..."]:6: attempt to index field 'TimeSignature' (a userdata value)

What am I doing wrong?

If I try this instead

if not measure.GetTimeSignature():IsIdentical(lastmeasure.TimeSignature)


I get "[string "allmeasures = finale.FCMeasures() ..."]:6: bad argument #1 to 'GetTimeSignature' (FCMeasure expected, got table)"

Does "each()" produce a table rather than a FCMeasure?

Your script was almost correct. each() indeed produces FCMeasure objects in your script.

TimeSignature is a property and should be preceeded with a '.'

GetTimeSignature() and IsIdentical() are method calls and should be preceeded with a ':'

This version should work:

local allmeasures = finale.FCMeasures()
allmeasures:LoadAll()
lastmeasure = finale.FCMeasure()
for measure in each(allmeasures) do
    if measure.ItemNo > 1 then
        if not measure.TimeSignature:IsIdentical(lastmeasure.TimeSignature)
        or not measure.KeySignature:IsIdentical(lastmeasure.KeySignature)
        then
            lastmeasure.Barline = finale.BARLINE_DOUBLE
            lastmeasure:Save()
        end
    end
    lastmeasure = measure
end

Except for the "local", that's what I had in my original posting, and I still get

[string "local allmeasures = finale.FCMeasures() ..."]:6: attempt to index field 'TimeSignature' (a userdata value).

I suspect I don't have the latest versions of everything. Will investigate.

D-oh! I just needed the latest JW Lua. Since JW Plug-in Manager doesn't manage it I had never updated it. Thanks for your help and sorry for the false alarm. I am excited to be learning this and predict great things to be gained.

Is there access to the displayed time signature, by the way? Since I rarely use that, it's no big deal if not, but ideally these double barlines are based on what the player sees, not the underlying Finale time signatures. Conceivably, one could have a split measure or something.

These FCMeasure properties should work:
FCMeasure.UseTimeSigForDisplay (boolean)
FCMeasure.TimeSignatureForDisplay (FCTimeSignature object)

Jari,

Looks like FCNote:GetString() doesn't observe "simplify key" in the transposition. For example, in the concert key of F# major, the Bb Clarinet's key signature would be Ab major, and GetString() returns "E#" for a written F. Any work-around?

(If you would prefer I take my questions to the mailing list, I'm happy to do so.)

That would be better, as it is the de facto clearing house for all things JW Lua related, not this forum.  Besides, there are list members who do not look at this forum.
