[JW Lua] Determining the current page

[Charles O. Lawrence]

Herbert et al,

 

You may find that using the algorithm in a simple function might make your
code easier to write and follow, especially if you need it many times.
Something like this:

 

function isEven(a)

return (a%2) == 0 end

 

-- usage

for x=-10,10 do

    if isEven(x) then

        print(x," is even")

    else

        print(x," is odd")

    end

end

Is it also possible to determine if the page in focus is a left or right
page via the FCUI?

 

AFAIK, the first page is always a right page in Finale, so this should do
it:

isrightpage = (finenv.UI().CurrentPage % 2) ~= 0

(The '%' is modulo in Lua. '~=' is "not equal to" in Lua.)




Best regards,
