Copy and Paste for Framer.sketchplugin

// (shift cmd c)

// This plugin copies FramerJS boiler plate code for the currently selected layer.
// Example:

/*

	# Import Table Cell from Sketch
	tableCell = layers.Table_Cell

	# Add states for Table Cell
	tableCell.states.add
		hidden: {opacity: 0}

	# Animation options for Table Cell
	tableCell.states.animationOptions =
		curve: "ease-in"
		time: 0.25

	# Interaction for Table Cell
	tableCell.on Events.Click, ->
		tableCell.states.next()
