[JW Lua] Snippet Exchange: Swap layers

[Bart Visser]

Hi all,

I learn a lot from this list and from the examples on the website. Because most scripts are build from smaller components, I thought it would be helpful (for me and others) so share some snippets on this list. This makes it easier for new members to get going. It also gives the more experienced users small units to use in their more complicated scripts.

Below I've pasted a small snippet: Swap Layers.

function swap_layers(input_layer_x, input_layer_y)
	local region = finenv.Region()
	local selection = finale.FCMusicRegion()
	selection:SetRegion(region)

	for s = selection.StartStaff, selection.EndStaff do
		local layer_a = finale.FCNoteEntryLayer((input_layer_x-1), s, selection.StartMeasure, selection.EndMeasure)
		layer_a:Load()

		local layer_b = finale.FCNoteEntryLayer((input_layer_y-1), s, selection.StartMeasure, selection.EndMeasure)
		layer_b:Load()

		layer_a.LayerIndex = input_layer_y-1
    	layer_a:Save()
		layer_b.LayerIndex = input_layer_x-1
		layer_b:Save()
	end
end

swap_layers(1, 2)

I'll post more snippets in the coming days. If others find this useful, maybe you can post a snippet or two as well.

Cheers,


Bart Visser
