If you just need to find the nodes, there’s no reason to select them. Here’s a
quick function that will walk up the tree (and into groups) and give you back a
set containing all the Read nodes upstream of the input node (selectedNode() if
nothing is passed).
def recursiveFindReads(node=None, group=nuke.root(), reads=None):
if reads is None:
reads = set()
if node is None:
node = nuke.selectedNode() # Let this error on purpose if no node
selected
for n in node.dependencies(nuke.INPUTS | nuke.HIDDEN_INPUTS):
cls = n.Class()
if cls == 'Read':
reads.add(n)
elif cls == 'Group':
reads = reads.union(recursiveFindReads(node=[x for x in n.nodes()
if x.Class() == 'Output'][0], group=n, reads=reads))
else:
reads = reads.union(recursiveFindReads(node=n, group=group,
reads=reads))
return reads

Subject: Re: [Nuke-python] selecting a node from its name
One more thing - you should probably check to make sure the selected node is
not None!
if selectedNode != None:
# do the rest

what I am trying to do is write a script that finds all the read nodes
above a selected node in the graph.
so what I figure I have to do is
get the dependencies of a node and loop through testing if they are a read
node and continue recursively
for a in nuke.selectedNode().dependencies():
name = a.name()
for n in name:
select n:
if n.Class() == ?Read?:
but I don't know how to select a node from its name
can someone please help? I will accept any suggestions on how to make this
easier as well!
Thanks

I think this situation absolutely requires that a really futile and stupid
gesture be done on somebody's part. And we're just the guys to do it.
