Hi,
thanks for your answer. I'm trying to modify poststampCopyPaste script:
http://cameroncarson.com/scripting/
Problem is it stores only single input. My idea was to replace postInput
with array where input of every PostageStamp is stored. Otherwise None
value is stored. If I had same node order after paste I could simply
check ith entry in postInput and if it is != None use it as input for
pasted PostageStamp.

nuke.selectedNodes() will return the selected nodes in the order they appear
on the node stack. In other words, the most recently selected or created
node will be at the top of the stack (and thus at the front of the returned
list).
When you paste them, they are created in script order (imagine reading
through a Nuke script in a text editor and creating nodes as you encounter
their class names). Thus, the most recently created node (the "bottom" node
in a simple tree) will end up at the top of the stack after pasting.
However, there is no way to predict the order in which a user selected a
collection of nodes. You could try to re-sort the selection into topological
order using one or more simple graph algorithms, but without knowing the
exact method Nuke uses to decompose a DAG, it may be hard to cover all
cases.
If you can provide a little more information about what you're trying to do,
it may help inform some solutions.

Subject: [Nuke-python] Node order after nodeCopy and nodePaste
Hi,
I'm modifying default copy paste behaviour
for n in nuke.selectedNodes():
#store some params in global array
nuke.nodeCopy(nukescripts.cut_paste_file())
nuke.nodePaste(nukescripts.cut_paste_file())
for n in nuke.selectedNodes():
#restore some params from global array
Problem is that node order in first loop is different from order in
second. For example
Copy:
ColorBars1
PostageStamp1
Paste:
PostageStamp2
ColorBars2
Is there any pattern which could be used to correlate copied and pasted
nodes?
regards
Adam
