Add guides for each selected nodes

Scripting
1

Trying to write a script that adds guides for each selected node/anchor separately. Just started learning python. So far I could manage adding as many guides to the baseline as the number of nodes in the selected glyph :smiley:

font = Glyphs.font
selectedLayer = font.selectedLayers[0]


for node in path.nodes: # (or path.anchors etc.))
	guideLine = GSGuide()
	print (guideLine)
	guideLine.position = NSPoint(0, 0)
	guideLine.angle = 0
	selectedLayer.guides.append(guideLine)

You haven’t defined path; the code may work because it takes previously used variable from cache (?), but you’ll get weird results and spend days finding the problem :smiley:

You can iterate over selected nodes with Layer.selection, no need to go through every point.
To change guide’s position just take the position from the node position. Probably separate x and y? Check if a guide at that x/y already exists? :slight_smile:

font = Glyphs.font
selectedLayer = font.selectedLayers[0]

for node in selectedLayer.selection: 
	guideLine = GSGuide()
	guideLine.position = node.position
	guideLine.angle = 0
	selectedLayer.guides.append(guideLine)

Thank you so much for the explanation and correction
