Not authoritative; but I just checked a custom node that is Executable and
indeed a 'beforeRender' knob is added by Nuke.

Subject: Re: [Nuke-python] How to check if a Node is executable?
To: nuke-python@support.thefoundry.co.uk
nuke.allNodes('Write') will only return nodes of the Write Class, so just
"Write" nodes. Many other nodes (classes) can be executed, like GenerateLUT,
CurveTool, WriteGeo, DeepWrite, etc.
I think it's a safe bet to check for the existence of knob named "before
render", otherwise you would have to check for knobs named "go", "render",
"execute", "generate", etc which would be odd.
Personally I don't know of any other way to identify executable nodes aside
that one at least.

Aren't executable nodes always of type Write?If so, this could be what you're
looking for?
Select some node and run the script to check whether it's executable or not.
[snip]
def isExecNode( someNode ): execNodes = nuke.allNodes('Write')
print execNodes for execNode in execNodes: if
someNode.name() in execNode.name():
return True else: return
False
if isExecNode( nuke.selectedNode() ): print 'Execute node: ' +
nuke.selectedNode().name()
else: print 'Do not execute node: ' + nuke.selectedNode().name()
[/snip]

Hi everyone,
Is there an official way to check if a node is executable? I was just going to
check if it has a 'beforeRender' knob, but wasn't sure that covers all cases.
As always, thanks so much!-Paul
