Convert multiple line segments into curve segments

Glyphs
1

I’d love the ability to convert multiple line segments into curve segments. My habit is to put down all nodes at once first. So for example in a glyph like S , there is a lot of Option-Clicking to do. Is this a feature that exists somewhere?

That is currently not possible. And there will always be segments (except in an “o”) that doesn’t need curves. So I wonder what is more efficient: Adding all needed segments one by one or converting all and removing the unneeded ones.

There a script which does that.
Will post once I get to my laptop.

def lerp(t, a, b):
	return NSPoint(int((1-t)*a.x + t*b.x), int((1-t)*a.y + t*b.y))

Layer = Glyphs.font.selectedLayers[0]
testSelection = len(Layer.selection) > 0

for p in Layer.paths:
	if p.closed:
		start = -1
	else:
		start = 0
	for idx in range(len(p.nodes) - 1, start, -1):
		node = p.nodes[idx]
		if testSelection and not node.selected:
			continue
		if node.type == LINE:
			prevNode = p.nodes[idx - 1]
			off1 = GSNode(lerp(0.33, prevNode.position, node.position), OFFCURVE)
			off2 = GSNode(lerp(0.66, prevNode.position, node.position), OFFCURVE)
			p.nodes.insert(idx, off2)
			p.nodes.insert(idx, off1)
			node.type = CURVE
			# node.connection = GSSMOOTH

hope this code is helpful.
